 - Current checkpoints cover the Elwynn waterfall from front/side and Goldshire Inn/Blacksmith windows. Headless runs are dry-run only because the headless display server cannot produce viewport PNGs.
 
+## 2026-07-13 Renderer Shutdown Ownership
+
+- `StreamingWorldLoader` drains its asynchronous work before teardown, leaves parented streamed nodes to SceneTree ownership, then explicitly frees detached M2/WMO prototype nodes and clears resource caches.
+- `ADTBuilder` explicitly frees a temporary `Water` root when an ADT liquid payload produces no child geometry. Dry tiles must not leave empty nodes in ObjectDB.
+- `src/tools/verify_render_runtime_cache_shutdown.gd` regression-checks detached prototype and resource-cache release plus empty-liquid-root ownership. The unified render-baseline runner executes it before capture.
+- A focused 8-second GUI checkpoint and a seven-checkpoint single-pass GUI run finish without Node, renderer resource or RID leak diagnostics. A timing-dependent anonymous zero-reference `RefCounted` ObjectDB warning can remain at engine teardown; it is tracked separately and is not suppressed.
+- This is shutdown-only ownership behavior and does not alter checkpoint rendering, cache formats or the `Blizzlike335` compatibility profile.
+
+## 2026-07-13 Explicit Streaming Focus
+
+- `StreamingWorldLoader` consumes an immutable `StreamingFocus` containing a
+  typed `GodotWorldPosition`; runtime streaming no longer discovers the active
+  `Camera3D` from the viewport or child nodes.
+- Eastern Kingdoms and Kalimdor runtime scenes explicitly use the player as the
+  streaming source. Checkpoint capture and terrain/occluder probes explicitly
+  use their dedicated camera through the same public refresh path.
+- The editor viewport camera remains behind a dedicated editor-only adapter.
+  `camera_path` is retained solely for optional automatic overview positioning.
+- Streaming radii, LOD decisions, cache formats and renderer quality profiles
+  are unchanged by this migration.
+
+## 2026-07-13 Coordinate Conversion Boundary Gate
+
+- Sky/area lookup, streaming tile ownership, player spawn/terrain sampling and
+  terrain diagnostics now cross world-coordinate spaces through typed
+  `CoordinateMapper` methods.
+- Renderer distance, LOD, ray and model-local M2/WMO calculations remain in
+  their existing Godot/local spaces; they are not axis conversions.
+- The repository gate rejects new manual world-center, WoW/Godot and
+  Godot-position-to-ADT formulas. The unified renderer baseline runs this gate.
+- Native ADT/WDT parsers keep one shared world conversion in
+  `wow_chunk_reader.h`; the independent M00 calibration formula remains a test oracle.
+- Coordinate contract version 2, renderer radii, cache formats and visual
+  quality profiles are unchanged.
+
+## 2026-07-13 Golden Server Spawn Renderer Evidence
+
+- The pinned AzerothCore Human Warrior start at server position
+  `(-8949.95, -132.493, 83.5312)` maps through `CoordinateMapper` to Godot
+  `(17199.159666667, 83.5312, 26016.616666667)`, ADT `(32,48)` and MCNK `(3,12)`.
+- `server_spawn_render_manifest.json` drives the ordinary Eastern Kingdoms
+  checkpoint capture pipeline at that location; no live database or production
+  spawn entity is introduced.
+- A renderer-native emissive marker starts at the exact mapped origin and keeps
+  depth testing enabled so GUI evidence exposes its relationship to terrain.
+- `verify_server_spawn_renderer.gd` rejects drift between the pinned fixture,
+  manifest target/player coordinates and expected ADT ownership. The unified
+  renderer baseline runs this contract check before capture.
+- This closes a coordinate/renderer integration criterion only. It does not
+  claim TrinityCore row equivalence or visual parity with the original client.
+
+## 2026-07-15 WorldRenderFacade First Seam
+
+- Runtime streaming scenes, checkpoint capture and renderer probes now submit
+  typed focus through `WorldRenderFacade`; those callers no longer call the
+  monolithic streamer's focus methods or configure its focus source directly.
+- Baseline capture reads queue/cache/activity counts through
+  `renderer_metrics_snapshot()`. The facade returns a deep copy, so diagnostics
+  cannot mutate renderer-owned state.
+- `StreamingWorldLoader` remains the internal implementation and still owns all
+  queues, tasks, caches, nodes and RIDs. The facade adds no parallel state or
+  replacement scheduler.
+- This package does not alter targets, budgets, cache versions, placement,
+  visibility, materials or animation. Environment, entity visuals and ground
+  query remain explicit follow-up facade contracts in M03.
+
+## 2026-07-15 StreamingTargetPlanner Extraction
+
+- Runtime and editor wanted/retained ADT set calculation now lives in the
+  scene-free `StreamingTargetPlanner`.
+- `StreamingTargetPolicy` preserves existing chunk/tile radii, warm/prewarm/
+  retain margins and the clamped boundary-prefetch threshold.
+- `StreamingTargetPlan` freezes its focus/wanted/retained result; the streamer
+  still owns available paths, load-queue distance sorting, loaded-tile LOD/detail
+  state, async work, caches, nodes and RIDs.
+- Asset-free fixtures cover center, edge/corner prefetch, catalog filtering,
+  clamp and editor behavior plus bounded High-like iteration timing.
+- Cache versions, quality profiles, queue priority and visible rendering rules
+  are unchanged by the extraction.
+
+## 2026-07-16 RenderBudgetScheduler Extraction
+
+- The scene-free `RenderBudgetScheduler` now owns the per-frame counters for 16
+  named renderer operation lanes. It owns no queue, task, cache, Node or RID.
+- `StreamingWorldLoader` snapshots its existing exported limits once per process
+  frame and asks for a boolean permit immediately before each historically
+  budgeted operation.
+- Chunk removals and creations intentionally share one `chunk_geometry` lane;
+  the existing removal-first drain order and combined limit are preserved.
+- Loader teardown cancels permit issuance before waiting for asynchronous work.
+  Existing worker/result staleness checks and resource cleanup remain unchanged.
+- Asset-free contracts cover exact bounds, independent/shared lanes, frame reset,
+  invalid inputs, terminal cancellation, detached diagnostics and hot-path timing.
+- Defaults, quality presets, queue order, cache versions and visible rendering
+  rules are unchanged. Asset-backed p95/p99 comparison remains required.
+
+## 2026-07-16 Streamer Internal Access Gate
+
+- `verify_renderer_internal_access.gd` derives private queue, task, cache and
+  tile-state field names from `StreamingWorldLoader` declarations and rejects
+  external member/reflection access in gameplay and Godot `EditorPlugin` package sources.
+- The gate follows the implementation inventory instead of duplicating a manual
+  list, so a newly named private renderer field is covered automatically when it
+  matches those ownership categories.
+- Scene composition may still reference the loader script and the facade's
+  implementation path; those are composition details, not mutable queue access.
+- Renderer diagnostic probes are added explicitly as their facade contracts land.
+- This is a source-only boundary check and changes no renderer behavior or fidelity.
+
+## 2026-07-16 Rendered Ground Query Facade
+
+- `WorldRenderFacade.sample_ground_height()` accepts `GodotWorldPosition` and
+  returns renderer-owned immutable `RenderedGroundSample` from already loaded
+  quality/tile-LOD render meshes, avoiding a render-to-gameplay dependency.
+- Its factories load the predeclared Script path instead of relying on a warm
+  global-class cache; a dedicated cold-start verifier covers this bootstrap path.
+- `renderer_ground_query_snapshot()` preserves the terrain probe's tile readiness,
+  queue position, mesh bounds and nearby seam-fallback diagnostics as a detached
+  Dictionary; callers receive no queue, tile-state, Mesh or Node reference.
+- `probe_render_terrain_height.gd` now uses this facade snapshot and no longer reads
+  `_tile_states`, `_tile_load_queue`, `_tile_loading_tasks` or `_available_tiles`.
+- Gameplay continues using the independently composed M02 `TerrainQuery`/
+  `AdtTerrainQuery`. Loaded render meshes are diagnostic and are not authoritative
+  movement collision.
+- The ray height, 3x3 tile search and `2/5/10/20/40`-unit nearby fallback are
+  preserved. No terrain geometry, cache, streaming or visual behavior changed.
+
+## 2026-07-16 Terrain Chunk LOD Planner Extraction
+
+- `TerrainChunkLodPlanner` now owns the pure mapping from populated parsed ADT
+  chunk indices to desired terrain LOD 0/1/2.
+- `TerrainChunkLodPolicy` snapshots the existing enabled flag, three raw chunk
+  radii and chunk size once per streaming-target application.
+- Horizontal XZ distance to the chunk center, inclusive squared thresholds,
+  sparse-index omission and historical negative-radius squaring are unchanged.
+- `StreamingWorldLoader` still owns tile/chunk state, queues, operation budgets,
+  creation/removal, Mesh/Node/RID finalization and tile-LOD fallback.
+- Cache formats, quality presets and visible behavior are unchanged. The
+  scene-free contract is formula evidence only; asset-backed p95/p99 and visual
+  acceptance remain required.
+
+## 2026-07-16 Terrain Chunk Geometry Queue Planner Extraction
+
+- `TerrainChunkGeometryQueuePlanner` now compares current and desired chunk state
+  and returns fresh chunk create/remove request arrays.
+- LOD mismatches and absent chunks retain the existing request shape; creates
+  remain sorted by horizontal distance from chunk origin to streaming focus.
+- Desired tile LOD still removes every current chunk, while sparse parsed chunk
+  records retain the existing tile-origin distance fallback.
+- `StreamingWorldLoader` still owns queue storage/drains, removal-first execution,
+  the shared `chunk_geometry` budget lane and every Mesh/Node/RID side effect.
+- Cache formats, quality profiles and visual rules are unchanged. Asset-backed
+  p95/p99 and visual acceptance remain required.
+
+## 2026-07-16 M2 Unique Placement Registry Extraction
+
+- `M2UniquePlacementRegistry` now owns positive ADT `MDDF.uniqueId` reservations
+  across streamed tiles using the existing `uid:<decimal>` keys.
+- Missing/zero/negative IDs remain untracked; duplicates inside one reservation
+  call are suppressed and another tile records one skipped key until owner release.
+- Owner release still lets the loader find eligible waiting tiles and enqueue the
+  existing detail retry path. First ownership remains tile-processing-order based.
+- `StreamingWorldLoader` still owns tile state, retry queues, grouping/build tasks,
+  M2 caches, MultiMesh/Node/Mesh/material/RID creation and all operation budgets.
+- M2/ADT cache formats, transforms, profiles and visible rules are unchanged.
+  Asset-backed cross-boundary p95/p99 and visual acceptance remain required.
+
+## 2026-07-16 M2 Placement Transform Resolver Extraction
+
+- `M2PlacementTransformResolver` now owns the pure ADT M2 basis and local
+  origin-compensation formulas used by worker grouping, placeholders and direct
+  instance creation.
+- Regular models retain `Basis.from_euler`; `ElwynnCliffRock01/02` retain their
+  narrow shell correction; `NewWaterfall` and `ElwynnTallWaterfall01` retain
+  calibrated world yaw, local fall-axis twist and tall-sheet anchor compensation.
+- Path separator/case/MDX handling, constants and caller-specific final scale
+  clamps are unchanged. The resolver owns no Node, task, cache or RID.
+- Cache formats, placement positions and visible rules are unchanged by the
+  extraction. Asset-backed visual recheck and general placement parity remain gaps.
+
+## 2026-07-16 M2 Placement Grouper Extraction
+
+- `M2PlacementGrouper` now owns pure worker-side validation, historical path
+  normalization and ordered tile-local transform grouping of ADT M2 placements.
+- Invalid records, backslash replacement, lowercase `.mdx/.mdl` conversion,
+  first-seen ordering and the `0.0001` scale clamp are unchanged.
+- The loader retains tasks, mutex/result queues, stale-result checks, tile/build
+  state, caches and all Node/MultiMesh/Mesh/material/RID finalization.
+- Cache formats, batching, profiles and visible rules are unchanged. Asset-backed
+  traversal p95/p99, visual recheck and spatial-cell grouping remain pending.
+
+## 2026-07-17 M2 Build Batch Planner Extraction
+
+- `M2BuildBatchPlanner` now owns pure static/animated batch-limit selection,
+  remaining-count capping and next-offset/group-completion calculation.
+- Existing animated/static limits still clamp to at least one; resource readiness,
+  queue rotation, serial progression and `M2_BUILD` permit consumption are unchanged.
+- The loader retains build jobs/queues, tile cancellation, animation/mesh caches,
+  retries and all Node/MultiMesh/Mesh/material/RID finalization.
+- Cache formats, quality profiles, batching output and visible rules are unchanged.
+  Asset-backed p95/p99 and spatial-cell batching evidence remain pending.
+
+## 2026-07-17 M2 Runtime Mesh Rebuild Classifier Extraction
+
+- `M2RuntimeMeshRebuildClassifier` now owns the memoized decision used when a
+  stale cached M2 mesh may need an in-memory rebuild from raw data.
+- Existing triggers are unchanged: any billboard flag/positive billboard vertex
+  count, or a referenced non-identity UV rotation/absolute rotation speed above
+  `0.000001` across at most four texture stages.
+- Invalid batch variants and combo/transform indices remain skipped. The first
+  decision for a normalized path remains cached until the same two historical
+  map/shutdown clear sites.
+- `StreamingWorldLoader` still loads raw M2 data, checks
+  `M2_MATERIAL_REFRESH_VERSION`, calls `M2Builder`, adopts/falls back to Meshes
+  and owns ResourceLoader/finalization budgets.
+- No cache version, shader, material, geometry or visible rule changed. Synthetic
+  predicate timing is not asset-backed descriptor-pressure/p95/p99 evidence.
+
+## 2026-07-17 WMO Placement Resolver Extraction
+
+- `WmoPlacementResolver` now owns lowercase/slash cache-key normalization,
+  positive MODF `uid:<decimal>` identity with the legacy tile/index fallback and
+  world `Transform3D` composition.
+- Lightweight render roots, cached scenes and live prototypes now share the same
+  position/Euler/unclamped-scale formula.
+- The loader retains registry refs, jobs/queues, cache/load state, resource
+  fallback, cancellation and all Node/Mesh/MultiMesh/material/RID ownership.
+- Cache formats, placement values, profiles and visible rules are unchanged.
+  Asset-backed placement/p95/p99 and general WMO parity remain pending.
+
+## 2026-07-17 WMO Render Resource Cache State Extraction
+
+- `WmoRenderResourceCacheState` now owns validated lightweight-WMO render
+  Resources, negative entries and normalized-path to pending-cache-path records.
+- `StreamingWorldLoader` still constructs cache paths, calls `ResourceLoader`,
+  polls requests and validates `WMOStreamingResource` script identity plus
+  `FORMAT_VERSION` before completing cache state.
+- Map reset and orderly request draining clear pending/negative state while
+  retaining accepted Resources; final runtime cache release clears all state.
+- Missing render-cache files still are not negatively cached, preserving retry
+  and cached-scene/live fallback behavior. Formats, profiles and visuals are unchanged.
+- Asset-backed corrupt-cache, traversal/leak p95/p99 and paired fidelity evidence
+  remain pending.
+
+## 2026-07-17 WMO Scene Resource Cache State Extraction
+
+- `WmoSceneResourceCacheState` now owns validated cached-WMO PackedScenes,
+  negative entries and normalized-path to pending-`.tscn` records.
+- `StreamingWorldLoader` still checks file existence and
+  `wmo_max_runtime_scene_mb`, calls `ResourceLoader`, instantiates a validation
+  probe, checks WMOBuilder cache metadata and frees the probe before adoption.
+- Missing files, oversize scenes, request errors, load failures and stale scenes
+  retain their prior negative-cache and live-prototype fallback behavior.
+- Map reset clears pending/negative state while retaining accepted scenes; final
+  shutdown releases all scene state. Formats, profiles and visuals are unchanged.
+- Asset-backed oversize/stale fixtures, traversal/leak p95/p99 and paired fidelity
+  evidence remain pending.
+
+## 2026-07-17 ADT Water Load Pipeline State Extraction
+
+- `AdtWaterLoadPipelineState` now owns ADT water pending FIFO/deduplication,
+  active WorkerThreadPool task IDs and the mutex-protected parsed-result mailbox.
+- `StreamingWorldLoader` still selects concurrency, starts/waits tasks, invokes
+  `ADTLoader`, consumes `WATER_FINALIZE` permits, rejects stale tile/path/root
+  results and owns `water_loaded` timing. Main-thread Water subtree construction
+  and attachment are delegated separately as described below.
+- Tile release still cancels only pending water requests; active work completes
+  and its result is discarded when tile ownership is stale. Shutdown waits task
+  IDs before clearing state; reset does not interrupt workers.
+- Pending-plus-active `water` metrics, parsing, formats, materials, profiles and
+  visible behavior are unchanged.
+- Asset-backed MH2O/MCLQ fidelity, long-traversal leak/p95/p99 and paired capture
+  evidence remain pending.
+
+## 2026-07-17 ADT Water Scene Finalizer Extraction
+
+- `AdtWaterSceneFinalizer` now owns the two main-thread operations that turn
+  validated parsed ADT data into a Water subtree: the existing
+  `ADTBuilder.build_tile_water_scene` call and attachment to the tile root.
+- Both raw tile finalization and delayed cached-tile water results use the same
+  service. Optional persisted Editor ownership is assigned recursively only
+  when the loader supplies its existing edited-scene owner.
+- The service is stateless and retains no Node, Mesh, material or RID. The tile
+  SceneTree subtree remains the lifetime owner; dry data still causes ADTBuilder
+  to free its temporary empty Water root.
+- Parsing, task/result state, concurrency, stale validation, `WATER_FINALIZE`
+  permits, `enable_water` and `water_loaded` timing remain loader-owned.
+- Geometry, materials, coordinates, cache formats, profiles and visible output
+  are unchanged. Synthetic geometry/ownership evidence is not an MH2O/MCLQ or
+  original-client parity claim; asset-backed traversal/p95/p99 remains pending.
+
+## 2026-07-16 World Environment Snapshot Facade
+
+- `WorldEnvironmentSnapshot` carries one immutable finite time-of-day value,
+  normalized to `[0, 24)` hours; invalid non-finite input is explicit.
+- `WorldRenderFacade.apply_environment_snapshot()` delegates the snapshot to the
+  scene-owned `WowSkyController`. The facade owns no `Environment`, sun, skybox,
+  shader global or DBC sampling state.
+- Checkpoint capture now submits its manifest time through the facade instead of
+  locating `WowSkyController` and mutating `use_system_time`, `time_speed` and
+  `fixed_time_hours` directly.
+- Applying a snapshot performs the same three fixed-clock assignments as the old
+  capture path. Light/Area/Skybox DBC lookup, interpolation, fog, sun and shader
+  behavior remain unchanged; weather and indoor environment state are follow-up work.
+
+## 2026-07-16 World Entity Presentation Facade
+
+- `EntityPresentationSnapshot` contract version 1 combines session `EntityId`,
+  typed Godot world position, visual PackedScene path, finite yaw/scale and visibility.
+- `WorldRenderFacade.present_entity()` and `remove_entity()` delegate to an explicit
+  scene-owned `WorldEntityPresenter`; both runtime scenes compose that service.
+- The presenter owns only visual subtrees. Same-path snapshots update transform/
+  visibility, changed paths replace after successful instantiation, and removal
+  detaches plus queues the owned root for deletion.
+- The local player, authoritative state, GUID mapping and asset/display selection
+  remain outside this service. Runtime emits no entity commands yet, so baseline
+  output is unchanged.
+- PackedScene loading is currently synchronous on create/replace and is a documented
+  prototype limitation, not an accepted network-scale frame-critical path.
+
+## 2026-07-16 Terrain Quality Mesh Cache Extraction
+
+- `TerrainQualityMeshCache` now owns full-quality terrain revisit Mesh references,
+  tile-key LRU order and source admission outside `StreamingWorldLoader`.
+- The historical rules are unchanged: successful restore touches newest; store
+  trims oldest to `terrain_quality_mesh_cache_limit`; zero/negative capacity keeps
+  no entries; control-splat/splat sources are never retained in this revisit cache.
+- The loader keeps three narrow adapters: restore into tile state, store after a
+  full-quality result and clear during existing world reset/shutdown.
+- ADT parsing, quality tasks/results, tile state, cache format versions, material/
+  Node/RID finalization, budgets and visible terrain behavior remain loader-owned.
+
 ## Practical Rule For Future Work
 
 If something improves quality but creates visible hitch, it is not done. Move it to bake/cache/background work, split finalization over frames, or prewarm it before the player can see it.

+
+## Outcome
+
+Add private build 12340 evidence for the remaining sky-transition and native animated-M2 coverage, rerun all paired comparisons, and hand the resulting audit to the milestone integrator.
+
+## Non-goals
+
+- Committing proprietary screenshots or extracted assets.
+- Claiming renderer parity from mismatched world placement or animation phase.
+- Marking M00 DONE; only the milestone integrator may change target status or Evidence.
+
+## Paths
+
+- Exclusive: this claim and animation/sky evidence documentation
+- Shared/hotspots: `docs/M00_FINAL_PAIRED_EVIDENCE.md`, `docs/modules/world-renderer.md`
+- Generated/ignored: normalized private references under `sources/OpenWCReferenceCheckpoints`; captures and reports under `user://`
+
+## Contracts and data
+
+- Public API/events: unchanged
+- Schema/format version: unchanged
+- Migration/compatibility: existing five-reference comparison remains valid
+- Consumers: M00 milestone integrator
+
+## Dependencies
+
+- Requires: user-captured build 12340 screenshots at 19:00 and two real `GryphonRoost01` animation phases
+- Blocks: final integrator decision on M00 completion
+- External state: private screenshots remain outside Git
+
+## Verification
+
+- Commands: private-reference preparation, full baseline runner, comparator self-test, coordination and documentation gates
+- Fixtures: seven private build 12340 checkpoint references plus a second animation-phase provenance frame
+- Fidelity evidence: sky-transition screenshot and observed wing pose change over three seconds
+- Performance budget: existing M00 capture budgets
+
+## Documentation deliverables
+
+- Inline public API docs: unchanged
+- Module specification: paired coverage and remaining limitations
+- Data-flow diagram: unchanged
+- Sequence/state/dependency diagrams: unchanged
+- Source map/status updates: final paired evidence audit
+
+## Simplicity and naming
+
+- Important names introduced: none
+- Simplest considered solution: normalize private captures outside Git and reuse the existing comparator
+- Rejected complexity/abstractions: adding a video comparator or committing an asset corpus
+- Unavoidable complexity and justification: animation phase and synthetic placement require human evidence classification alongside pixel metrics
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: exact-size private references registered; real ADT placement verified; canonical and visual captures completed; fourteen comparisons audited
+- Next: milestone integrator reviews synthetic/real placement classification and GUI RID risk
+- Blocked by:
+
+## Handoff
+
+- Commit: this work-package commit
+- Results: `compared=14`, `failed=14`, `missing=0`; mean error `0.066893..0.176955`; original-client Gryphon wing phase changed over three seconds
+- Remaining risks: synthetic probe placement differs from the original-client world placement; GUI RID/resource diagnostics remain separate
+- Documentation updated: `docs/M00_FINAL_PAIRED_EVIDENCE.md`, `docs/modules/world-renderer.md`

+Jointly refine Goldshire checkpoint pitch and FOV against a WMO-ready build 12340 reference.
+
+## Non-goals
+
+- Changing runtime player camera defaults.
+- Changing manifest values without an interior optimum and human approval.
+- Optimizing yaw beyond the ready-scene coarse result.
+
+## Paths
+
+- Exclusive: joint FOV option in camera-pose sweep and framing evidence
+- Shared/hotspots: camera-pose operational documentation and renderer module findings
+- Generated/ignored: candidate PNGs and ranking JSON under `user://`
+
+## Contracts and data
+
+- Public API/events: additive `-CameraFovValues`; scalar `-CameraFov` remains compatible
+- Schema/format version: ranking schema remains version 1 with existing per-candidate FOV field
+- Migration/compatibility: scalar sweeps retain existing candidate paths
+- Consumers: M00 fidelity workflow
+
+## Dependencies
+
+- Requires: WMO-ready 8-second capture contract
+- Blocks: Goldshire manifest framing decision
+- External state: private build 12340 reference remains outside Git
+
+## Verification
+
+- Commands: joint-grid plan regression, real ready-scene sweep, comparator self-test, repository gates
+- Fixtures: private Goldshire Inn reference
+- Fidelity evidence: joint pitch/FOV ranking and human inspection
+- Performance budget: offline diagnostic
+
+## Documentation deliverables
+
+- Inline public API docs: PowerShell parameter
+- Module specification: framing finding
+- Data-flow diagram: FOV joins pose grid
+- Sequence/state/dependency diagrams: unchanged
+- Source map/status updates: operational guide
+
+## Simplicity and naming
+
+- Important names introduced: `CameraFovValues`, `effectiveCameraFovValues`
+- Simplest considered solution: one additional loop around the existing grid
+- Rejected complexity/abstractions: generic optimizer
+- Unavoidable complexity and justification: projection and pitch jointly affect framing
+- Measured optimization evidence: bounded 1x5x3 grid
+
+## Status
+
+- State: ready-for-review
+- Done: additive joint FOV grid, compatibility-preserving paths, plan regression, ready-scene 15-candidate ranking and human inspection
+- Next: add approved landmark/region scoring before any manifest camera calibration
+- Blocked by:
+
+## Handoff
+
+- Commit: this work-package commit
+- Results: numeric best FOV 62/yaw 10/pitch -25 at mean 0.078843 and ratio 0.667721 was visually rejected as grass-dominated; FOV 38/yaw 10/pitch -10 better matched building scale at mean 0.084220
+- Remaining risks: full-frame metric does not preserve landmark framing; no manifest values were changed
+- Documentation updated: `docs/CAMERA_POSE_SWEEP.md`, `docs/modules/world-renderer.md`

+- Results: before the fix the focused capture retained 6 mesh, 6 material, 4 shader, 6 texture, 6 instance and RenderingDevice RIDs (30 resources); after the fix focused and seven-checkpoint captures retained none
+- Remaining risks: D3D12 descriptor fallback remains unrelated; Godot can report a timing-dependent anonymous `RefCounted` whose reference count is already zero, without retained Node/resource/RID ownership
+- Documentation updated: `RENDER.md`, `docs/modules/world-renderer.md`, `docs/M00_FINAL_PAIRED_EVIDENCE.md`; existing renderer shutdown sequence updated, no new diagram required

+- Inline public API docs: PowerShell default
+- Module specification: corrected readiness/fidelity finding
+- Data-flow diagram: readiness precondition
+- Sequence/state/dependency diagrams: unchanged

+
+## Simplicity and naming
+
+- Important names introduced: none
+- Simplest considered solution: reuse the manifest's measured 8-second stabilization default

+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Route remaining GDScript world/tile axis conversions through `CoordinateMapper`
+and add a repository-wide gate that rejects new manual world-center, axis-swap
+or world-to-ADT tile formulas outside explicit contract/native-oracle boundaries.
+
+## Non-goals
+
+- Rewriting model-local M2/WMO vertex or placement orientation transforms.
+- Moving renderer distance/LOD geometry out of Godot space.
+- Replacing the native parser boundary with GDScript calls from worker threads.
+- Changing coordinate contract semantics, renderer radii or cache formats.
+
+## Paths
+
+- Exclusive: `src/tools/verify_coordinate_conversion_boundaries.gd`
+- Shared/hotspots: `src/domain/coordinates/coordinate_mapper.gd`, coordinate
+  tests/docs/ADR, streamer/player/sky/terrain-probe consumers,
+  `docs/CODING_STANDARD.md`, this claim
+- Generated/ignored: Godot import metadata, extracted assets and renderer caches
+
+## Contracts and data
+
+- Additive mapper methods: Godot position to ADT tile/local and ADT tile/local
+  to Godot position
+- Native exception: one formula definition in `src/native/src/wow_chunk_reader.h`;
+  ADT/WDT loaders may call it but may not define copies
+- Oracle exception: `verify_render_coordinate_calibration.gd` retains one
+  independent M00 formula to detect common-mode mapper regressions
+- Model-local transforms are outside the world-coordinate gate
+
+## Dependencies
+
+- Requires: coordinate contract v2 and M01 seams through `7c64e8d`
+- Blocks: M01 coordinate-centralization exit criterion and milestone evidence audit
+- External state: no dependency or proprietary input
+
+## Verification
+
+- Commands: conversion-boundary gate, mapper/golden fixtures, streaming focus,
+  identities, renderer calibration/manifest and repository gates
+- Fixtures: Godot/ADT tile center, local offsets and exact boundaries
+- Fidelity evidence: existing build-12340 points and raw ADT/server fixture remain unchanged
+- Performance budget: mapper allocations occur only at adapter/update boundaries;
+  renderer distance/LOD math remains in Godot scalars
+
+## Documentation deliverables
+
+- Inline public API docs: new mapper methods
+- Module specification/ADR: boundary APIs, allowed exceptions and gate behavior
+- Coding standard: mandatory review rule for cross-space conversions
+- Data-flow diagram: existing coordinate module diagram updated for direct adapters
+- State/sequence diagrams: unchanged; pure synchronous mapping
+
+## Simplicity and naming
+
+- Important names introduced: `godot_to_adt_tile`, `godot_to_adt_tile_local`,
+  `adt_tile_local_to_godot`, `verify_coordinate_conversion_boundaries`
+- Simplest considered solution: extend the existing mapper and scan source text
+  for narrow high-signal formula signatures
+- Rejected complexity/abstractions: generic coordinate algebra framework,
+  native-to-GDScript calls on parser workers and a broad numeric-literal ban
+- Unavoidable complexity and justification: one native boundary and one
+  independent test oracle must remain explicit to avoid worker coupling and common-mode tests
+- Measured optimization evidence: existing renderer distance/LOD scalar math is unchanged
+
+## Status
+
+- State: ready-for-review
+- Done: mapper extensions, consumer migration, repository gate, review rule,
+  integrated renderer gate, regression fixtures and documentation
+- Next: integrator review, merge and M01 completion-evidence audit
+- Blocked by:
+
+## Handoff
+
+- Commit: `47dec6c`
+- Branch: `work/sindo-main-codex/m01-coordinate-boundary-gate`
+- Outcome: all audited GDScript world/tile conversions in sky, streaming,
+  player spawn/ground sampling and terrain probes route through typed
+  `CoordinateMapper` boundaries. A repository scan rejects new manual
+  world-center, legacy axis-conversion, world-to-tile, tile-local and
+  tile-center formulas.
+- Contract/schema: additive `godot_to_adt_tile`,
+  `godot_to_adt_tile_local` and `adt_tile_local_to_godot` APIs; no persisted
+  format, cache version or renderer radius changes.
+- Verification: CoordinateConversionBoundaries PASS (`83` files, one native
+  boundary, one independent oracle, four consumers, six classifier guards);
+  CoordinateMapper PASS (`5` golden points, `8` tile boundaries, `2` raw MCNK,
+  `5` yaw cases); renderer calibration PASS (`5` points, maximum error
+  `0.000015`); renderer manifest PASS (`7/7/7`); unified render baseline dry-run,
+  headless project load, runtime cache shutdown, coordination, documentation
+  and whitespace gates passed.
+- GUI regression: final ADT-boundary capture compared `2/2`, missing `0`,
+  failed `0` (cold mean `0.0002324`, changed ratio `0.0013741`; warm mean
+  `0.0000226`, changed ratio `0.0001285`). Earlier full capture produced all
+  `14` images; `11/14` met the strict changed-pixel threshold. The three
+  threshold-only differences retained low mean error (`<= 0.00622`) and were
+  visually classified as cold M2 readiness and liquid animation phase, with
+  unchanged camera, geometry alignment, area and streaming focus.
+- Fidelity: existing build-12340 calibrated points, raw ADT fixture and server
+  spawn fixture remain unchanged. Native parser workers retain exactly one
+  formula in `wow_chunk_reader.h`; the calibration verifier retains exactly one
+  independent formula so mapper and oracle cannot share a common-mode defect.
+- Rebuild: none. Local ignored extracted assets/native binary/cache junctions
+  were used for runtime checks and are not part of the commit.
+- Remaining risks: source scanning intentionally recognizes narrow high-signal
+  formula signatures rather than parsing arbitrary algebra; native formula
+  parity still relies on calibration/raw fixtures. Model-local M2/WMO basis
+  transforms and Godot-space LOD distance math are intentionally outside scope.
+- Recommended merge order: after `7c64e8d`; this package closes the remaining
+  M01 manual axis-conversion checklist item, but only the milestone integrator
+  may update target Evidence/status or set `OPENWC_TARGET_DONE`.
+- Documentation: coding review rule, coordinate-mapping module API/input-output/
+  data-flow/capability/risk/source-map sections, ADR 0001 and `RENDER.md` were
+  updated. Existing pure synchronous data-flow diagram remains authoritative;
+  no state/sequence diagram changed.

+- Target: M01
+- Program: FND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m01-coordinate-mapper`
+- Lease expires UTC: 2026-07-15
+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Introduce scene-free value objects for canonical WoW, server, ADT placement,
+ADT tile/chunk/local and Godot world coordinate spaces, plus the single pure
+`CoordinateMapper` contract for position and world-yaw conversions.
+
+## Non-goals
+
+- Migrating `StreamingWorldLoader`, native parsers, sky, player or renderer code.
+- Defining model-specific MDDF/MODF Euler rotation corrections.
+- Introducing `StreamingFocus`, typed IDs or a test framework dependency.
+- Claiming visual parity from arithmetic round trips.
+
+## Paths
+
+- Exclusive: `src/domain/coordinates/**`, `src/tools/verify_coordinate_mapper.gd`,
+  `docs/modules/coordinate-mapping.md`, `docs/adr/0001-canonical-world-coordinates.md`
+- Shared/hotspots: `docs/modules/README.md`, this claim
+- Generated/ignored: Godot import metadata and local test output
+
+## Contracts and data
+
+- Public API/events: immutable coordinate value objects and pure mapper methods
+- Schema/format version: no persisted format; contract version 1 in module docs
+- Migration/compatibility: additive contract; existing renderer conversions remain
+  unchanged until a later consumer migration package
+- Consumers: future renderer, network, gameplay and server-data adapters
+- Rollout order: contract and fixtures first, then native/parser and renderer consumers
+
+## Dependencies
+
+- Requires: merged M00 build 12340 coordinate calibration evidence
+- Blocks: M01 renderer coordinate migration and `StreamingFocus`
+- External state: no proprietary inputs; reference formulas are source-only evidence
+
+## Verification
+
+- Commands: headless coordinate contract probe, headless project load,
+  coordination and documentation gates
+- Fixtures: five build 12340 camera points, ADT map center/edge/boundary points,
+  server/ADT/Godot round trips and yaw normalization cases
+- Fidelity evidence: M00 observed build 12340 positions plus independent
+  OpenRealm/WoWee and TrinityCore grid formulas
+- Performance budget: constant-time scalar arithmetic with no allocation beyond result values
+
+## Documentation deliverables
+
+- Inline public API docs: every public value object and mapper method
+- Module specification: purpose, public API, inputs/outputs, ownership, errors and source map
+- Data-flow diagram: server/ADT/canonical/Godot mappings
+- Dependency diagram: canonical contract consumers and forbidden scene dependency
+- Sequence/state diagrams: not applicable; mapper is synchronous and stateless
+- ADR: coordinate axes, units, tile indexing and compatibility rollout
+
+## Simplicity and naming
+
+- Important names introduced: `CanonicalWowWorldPosition`, `ServerWorldPosition`,
+  `AdtPlacementPosition`, `AdtTileCoordinate`, `AdtChunkCoordinate`,
+  `AdtTileLocalPosition`, `GodotWorldPosition`, `WorldYaw`, `CoordinateMapper`
+- Simplest considered solution: scalar immutable value objects and one pure mapper
+- Rejected complexity/abstractions: generic vector-space framework, matrices,
+  dependency injection and a third-party test framework
+- Unavoidable complexity and justification: distinct source spaces prevent silent axis swaps
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: repository/reference audit, ADR, immutable value objects, pure mapper,
+  build 12340/boundary/yaw fixtures, module specification and repository gates
+- Next: integrator review and merge before renderer/native consumer migration
+- Blocked by:
+
+## Handoff
+
+- Commit: `f45695c`
+- Branch: `work/sindo-main-codex/m01-coordinate-mapper`
+- Outcome: additive contract for canonical/server/ADT/Godot positions, ADT
+  tile/chunk/local ownership and world-facing yaw; no existing consumer changed
+- Public contracts: contract version 1 documented in
+  `docs/modules/coordinate-mapping.md`; no persisted schema or cache change
+- Verification: coordinate mapper PASS (5 golden points, 8 tile boundaries,
+  5 yaw cases); M00 coordinate calibration PASS (5 points, maximum error
+  `0.000015`); renderer manifest, coordination, documentation, dependency and
+  whitespace checks passed; headless project load completed with expected
+  missing proprietary-data diagnostics in the isolated worktree
+- Fidelity: observed build 12340 positions match within `0.002` yard; formulas
+  cross-checked against TrinityCore, OpenRealm and WoWee; visual parity is not claimed
+- Migration/rebuild: none for this additive package; consumers migrate only
+  after merge and must preserve renderer checkpoints
+- Remaining risks: native loaders and renderer still use manual conversions;
+  MDDF/MODF Euler mapping is intentionally unresolved; server-spawn integration
+  and finite-value adapter validation remain later M01 packages
+- Recommended merge order: this contract first, coordinate fixtures/server-spawn
+  audit second, renderer/native consumers third, manual-conversion search gate last
+- Documentation: ADR 0001; coordinate-mapping module spec with data-flow and
+  dependency diagrams; inline API documentation on all public symbols

+- Lease expires UTC: 2026-07-15
+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Add scene-free, immutable identity values for stable authored content,
+session-local entities, opaque WoW wire GUIDs and namespaced server entries so
+callers cannot silently interchange their numeric/string representations.
+
+## Non-goals
+
+- Allocating Content IDs, Entity IDs or server entries.
+- Decoding WoW GUID high types before the build-12340 protocol package.
+- Defining map/spell/item/quest/display/sound IDs in this package.
+- Migrating gameplay, network or Content Project consumers that do not exist yet.
+
+## Paths
+
+- Exclusive: `src/domain/identity/`, `src/tools/verify_domain_identities.gd`,
+  `docs/modules/domain-identities.md`, `docs/adr/0002-domain-identity-namespaces.md`
+- Shared/hotspots: `docs/ARCHITECTURE.md`, this claim
+- Generated/ignored: Godot import metadata
+
+## Contracts and data
+
+- `ContentId`: canonical lowercase UUID text persisted with schema-owned content
+- `EntityId`: positive session-local integer, never a persisted content/server identity
+- `WowGuid`: opaque high/low unsigned 32-bit words preserving wire bits
+- `ServerEntryId`: positive integer plus non-empty adapter/table namespace
+- Migration: additive types only; no existing persisted data changes
+
+## Dependencies
+
+- Requires: M01 coordinate/focus seams through `77cd17a`
+- Blocks: Content Project schemas, server adapters, network entity mapping and gameplay registry
+- External state: no dependency or proprietary input
+
+## Verification
+
+- Commands: identity contract/boundary verifier, dependency search,
+  coordination/documentation gates and headless project load
+- Fixtures: valid/invalid UUIDs, session IDs, full unsigned GUID words and
+  duplicate numeric server entries in different namespaces
+- Fidelity evidence: GUID words remain opaque and lossless until build-12340
+  packet fixtures establish semantic decomposition
+- Performance budget: constant-time scalar/string validation outside frame loops
+
+## Documentation deliverables
+
+- Inline public API docs: every value and validation/equality method
+- Module specification: persistence, ownership, namespace mapping and recovery
+- Data-flow diagram: authored/runtime/wire/server identities into adapters
+- State/sequence diagrams: lifecycle diagram for content/session/wire/server identity
+- ADR: namespace separation and UUID persistence decision
+
+## Simplicity and naming
+
+- Important names introduced: `ContentId`, `EntityId`, `WowGuid`, `ServerEntryId`
+- Simplest considered solution: four independent values with explicit fields
+- Rejected complexity/abstractions: generic ID base class, registry service,
+  UUID generator and speculative GUID high-type enum
+- Unavoidable complexity and justification: server entry namespace and split GUID
+  words prevent collisions and signed 64-bit loss
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: four identity values, boundary verifier, ADR, module specification,
+  architecture mapping and repository gates
+- Next: integrator review and merge before the manual axis-conversion gate
+- Blocked by:
+
+## Handoff
+
+- Commit: `c1dc07c`
+- Branch: `work/sindo-main-codex/m01-domain-identities`
+- Outcome: authored content, runtime entities, WoW wire GUIDs and namespaced
+  server entries now have separate immutable scene-free value objects
+- Contract/schema: identity contract version 1; `ContentId` uses canonical
+  lowercase UUID text. No existing schema/cache is migrated; containing future
+  schemas still require their own version and duplicate/reference policy
+- Verification: DomainIdentities PASS (`5` ContentId, `5` EntityId, `6` WowGuid,
+  `5` ServerEntryId cases); StreamingFocus, coordinate golden fixtures and
+  CoordinateMapper PASS; M00 calibration PASS with maximum error `0.000015`;
+  renderer manifest PASS (`7` checkpoints); headless project load exit `0`;
+  coordination, documentation, naming/dependency and whitespace checks passed
+- Fidelity: `WowGuid` preserves two complete unsigned 32-bit wire words and
+  explicitly does not claim build-12340 high-type semantics without packet
+  fixtures; zero GUID remains an uninterpreted observable sentinel
+- Rebuild: none; no dependency or proprietary input. Clean-worktree project
+  load reports expected missing ignored extracted assets/character resources
+- Remaining risks: no ID allocator, mapping registry or server namespace
+  vocabulary exists yet; UUID shape does not enforce generator version/variant;
+  GDScript callers must use domain `equals` or canonical keys rather than
+  reference `==`
+- Recommended merge order: after StreamingFocus at `77cd17a`, before the M01
+  manual axis-conversion rule/search gate
+- Documentation: ADR 0002, domain-identities module API/input-output/data-flow/
+  lifecycle/persistence/recovery/capability/source-map sections, module registry
+  and architecture Domain mapping added or updated

+## Outcome
+
+Add a versioned, non-proprietary fixture and headless validator joining one

+
+## Non-goals
+
+- Committing ADT files, SQL dumps or original-client screenshots.

+
+## Contracts and data

+- Public API/events: no new production API; fixture schema version 1
+- Coordinate contract: version 2, unchanged
+- Migration/compatibility: additive test data; fixture consumers reject unknown schema versions
+- Consumers: M01 coordinate mapper, future native/renderer/server adapter migrations
+
+## Dependencies
+
+- Requires: merged coordinate contract version 2 at `b55bfca`
+- Blocks: coordinate consumer migration and golden server-spawn renderer integration
+- External state: source evidence reduced to pinned revision, numeric rows and SHA-256 hashes
+
+## Verification
+
+- Commands: fixture validator, coordinate mapper probe, M00 calibration,
+  manifest, coordination and documentation gates
+- Fixtures: AzerothCore Human Warrior start; raw `Azeroth_32_48.adt` MCNK
+  `(3,12)`; five build 12340 camera points
+- Fidelity evidence: exact source provenance and mapper outputs with bounded tolerances
+- Performance budget: negligible headless JSON and scalar arithmetic

+## Documentation deliverables
+
+- Inline public API docs: fixture-validator header and field validation functions
+- Module specification: fixture schema, provenance, verification and source map

+- State/sequence/dependency diagrams: unchanged; synchronous stateless validation
+
+## Simplicity and naming

+- Simplest considered solution: one JSON fixture and one existing-style headless script
+- Rejected complexity/abstractions: test framework dependency, SQL parser, ADT bytes in Git
+- Unavoidable complexity and justification: three independent source categories need explicit provenance
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: pinned source research, schema 1 fixture, headless validator, module

+- Blocked by:
+
+## Handoff
+
+- Commit: `ce4f7ec`
+- Branch: `work/sindo-main-codex/m01-coordinate-fixtures`
+- Outcome: one versioned fixture now joins a pinned AzerothCore Human Warrior
+  spawn, private raw MCNK metadata and five original-client build 12340 points
+  through coordinate contract version 2
+- Contract/schema: additive test fixture schema 1; production coordinate API and
+  contract version 2 are unchanged; proprietary bytes remain outside Git
+- Verification: golden fixture PASS (`1` server spawn, `1` raw ADT chunk, `5`
+  original-client points); CoordinateMapper PASS (`5` golden points, `8` tile
+  boundaries, `2` raw MCNK cases, `5` yaw cases); M00 calibration PASS with
+  maximum error `0.000015`; renderer manifest PASS (`7` checkpoints); coordination,
+  documentation, dependency and whitespace checks passed
+- Fidelity: AzerothCore source pinned at revision

+  `Azeroth_32_48.adt` SHA-256
+  `D66E27FD82B461AE38B78562952AED428E619777A3F3E35DD8FF97444644770A`;
+  server and raw data independently resolve tile `(32,48)` and chunk `(3,12)`
+- Rebuild: no proprietary input is required to rerun the committed fixture;

+- Integrator: sindo-main-codex, continuing the user-directed milestone workflow on 2026-07-14
+
+## Outcome
+
+Audit every merged M01 work package on current `master`, record final evidence,
+close M01 and activate M02 only if all target verification and documentation
+criteria pass.
+
+## Non-goals
+
+- Change coordinate, identity, streaming or renderer behavior.
+- Start M02 implementation.
+- Add new compatibility or visual-parity claims.
+- Commit proprietary assets, generated UIDs, caches or capture output.
+
+## Paths

+## Contracts and data
+
+- Public APIs, schemas, cache formats and migrations: unchanged
+- Coordinate contract remains version 2
+- Fixture schema remains version 1
+- Consumers: milestone sequence and M02 work packages
+
+## Dependencies
+
+- Requires: all seven M01 READY commits integrated through master `c8e99f2`
+- Blocks: M02 activation
+- External state: server-spawn GUI hashes and original-client numeric evidence are recorded; proprietary files remain outside Git
+
+## Verification
+
+- Commands: all M01 domain/fixture/boundary/focus/identity/spawn gates,
+  unified renderer dry-run, coordination/documentation checks and diff hygiene
+- Fidelity evidence: five build-12340 points, raw ADT metadata, pinned
+  AzerothCore spawn and cache-complete GUI marker capture
+- Performance: no runtime change; preserve recorded renderer cold/warm evidence
+
+## Documentation deliverables

+- Blocked by:
+
+## Handoff
+
+- Commit: `dd412e6`
+- Branch: `work/sindo-main-codex/m01-integrator-closeout`
+- Outcome: M01 is `DONE` with all seven checklist items and complete Evidence;
+  M02 is the only `ACTIVE` target and `targets/README.md` points to it.
+- Integration audit: all seven M01 READY commits are ancestors of master
+  `c8e99f2`; their claims now carry `OPENWC_INTEGRATION:ACCEPTED` markers.
+- Verification: unified renderer dry-run passed project load, material/dedupe/
+  shutdown gates, manifest `7/7/7`, calibration maximum error `0.000015`,
+  coordinate boundary (`84` files) and server-spawn renderer `(32,48)/(3,12)`;
+  coordinate mapper, golden fixtures, StreamingFocus and domain identity gates
+  passed. Coordination and documentation gates passed; coordination reports
+  only five already-expired M00 claim warnings.
+- Fidelity: closeout preserves five build-12340 coordinate observations, raw ADT
+  evidence, pinned AzerothCore spawn mapping and cache-complete Northshire GUI
+  evidence without claiming original-client visual parity or TrinityCore row
+  equivalence.
+- Rebuild/migration: none. Coordinate contract remains version 2; fixture schema
+  remains version 1; renderer cache formats are unchanged.
+- Remaining risks: recorded in M01 Evidence—TrinityCore populated spawn,
+  placement Euler parity, native parser boundary and broader renderer parity.
+- Documentation: M01 target Evidence/checklist, target index and roadmap current
+  state updated. Existing coordinate, identity and renderer module specs/API/
+  diagrams were audited and passed the documentation gate.

+
+## Non-goals
+
+- Connecting to a live AzerothCore or TrinityCore database.
+- Claiming TrinityCore spawn equivalence without a pinned populated TDB row.
+- Changing coordinate formulas, streaming radii, terrain, player movement or
+  production character presentation.
+- Adding proprietary assets or screenshots to Git.

+  coordinate/world-renderer module documentation, `RENDER.md`, this claim
+- Generated/ignored: Godot UIDs/import metadata and `user://` PNG/JSON evidence
+
+## Contracts and data
+
+- Fixture schema and coordinate contract version remain unchanged.
+- Additive diagnostic checkpoint metadata may request a renderer-native marker;
+  existing M00 checkpoints remain byte-for-byte compatible.
+- The spawn remains sourced from pinned AzerothCore revision
+  `68fcf0098b16388093989627f37be530fc91f07d`.
+
+## Dependencies
+
+- Requires: merged M01 packages through `a07a487`
+- Blocks: M01 golden server-spawn renderer criterion and milestone closeout
+- External state: GUI capture requires the existing local extracted/cached
+  renderer corpus; headless contract verification remains non-proprietary
+
+## Verification
+
+- Commands: dedicated spawn verifier, coordinate fixture/mapper/boundary gates,
+  renderer baseline dry-run, GUI checkpoint capture and human inspection
+- Fixture: AzerothCore race `1`, class `1`, map `0`, server position
+  `(-8949.95, -132.493, 83.5312)`
+- Expected renderer result: Godot position
+  `(17199.159666667, 83.5312, 26016.616666667)`, ADT `(32,48)`, MCNK `(3,12)`
+- Fidelity classification: server/coordinate integration evidence only; it does
+  not establish full original-client visual parity
+
+## Documentation deliverables
+
+- Inline API/tool documentation for new verifier and marker metadata
+- Coordinate-mapping module capability/evidence update
+- World-renderer checkpoint input/output/source-map update when marker support is added
+- Existing synchronous coordinate data-flow diagram updated only if flow changes
+
+## Simplicity and naming
+
+- Important names: `server_spawn_render_manifest`,
+  `verify_server_spawn_renderer`, `diagnostic_spawn_marker`
+- Simplest approach: reuse the existing checkpoint capture pipeline with one
+  dedicated manifest and a renderer-native diagnostic marker
+- Rejected complexity: live DB adapter, new scene-test framework and production
+  spawn entity implementation before the network/gameplay milestones
+- Performance: one diagnostic checkpoint outside production runtime
+
+## Status
+
+- State: ready-for-review
+- Done: fixture-to-renderer manifest/verifier, renderer-native marker, unified
+  baseline integration, cold/warm GUI evidence, documentation and log cleanup
+- Next: integrator review, merge cleanup/handoff and M01 closeout audit
+- Blocked by:
+
+## Handoff
+
+- Commits: implementation `24ddc99`; required cleanup `318e6ae`
+- Branch: `work/sindo-main-codex/m01-server-spawn-renderer`
+- Outcome: the pinned AzerothCore Human Warrior start is routed through
+  `CoordinateMapper` into the ordinary Eastern Kingdoms capture scene. A
+  depth-tested magenta marker begins at the exact mapped spawn origin.
+- Contract/schema: additive diagnostic manifest schema 1 and marker metadata;
+  coordinate contract version 2, production renderer APIs, cache formats and
+  `Blizzlike335` behavior are unchanged.
+- Verification: `SERVER_SPAWN_RENDERER PASS spawn=1 checkpoint=1 tile=32_48
+  chunk=3_12 profile=Blizzlike335`; unified renderer dry-run passed project,
+  materials, M2 dedupe, shutdown, `7/7/7` manifest, five-point calibration,
+  coordinate-boundary and server-spawn steps; coordinate golden fixtures,
+  mapper, StreamingFocus, domain identities, documentation and whitespace gates
+  passed. Coordination passed with five expired M00-claim warnings only.
+- GUI evidence: two `1280x900` cold/warm PNGs captured under
+  `user://server_spawn_renderer_m01_gui_run2`; focus tile `(32,48)`, terrain
+  quality `100/100`, missing cache `0`, queues drained, report results `2`.
+  Human inspection confirms the marker is on rendered terrain beside the road
+  at Northshire Abbey rather than below terrain or in an adjacent tile. PNG
+  hashes: cold `c08c43bcb75e5b3277105afb0d4e5a76caae9db91a7db64488770ffa03e32589`,

+- Fidelity: source remains AzerothCore revision
+  `68fcf0098b16388093989627f37be530fc91f07d`; server
+  `(-8949.95,-132.493,83.5312)` maps to Godot
+  `(17199.159666667,83.5312,26016.616666667)`, ADT `(32,48)`, MCNK `(3,12)`.
+  This proves coordinate/renderer integration, not original-client visual parity
+  or TrinityCore populated-row equivalence.
+- Runtime notes: D3D12 descriptor-heap initialization fell back to Vulkan;
+  optional ignored character/ambient GLB imports were unavailable. Neither
+  affected terrain/marker evidence. The known anonymous ObjectDB teardown
+  warning remained; no Node, renderer resource or RID leak diagnostic occurred
+  in the cache-complete run.
+- Repository hygiene: four accidentally committed local GUI logs are removed by
+  `318e6ae`; root `*.stdout.log`/`*.stderr.log` files are now ignored. Generated
+  PNG/JSON evidence and proprietary corpus remain outside Git.
+- Remaining risks: the diagnostic marker is not a production network entity;
+  live server adapters belong to M06/M08. Exact original-client character spawn
+  presentation and TrinityCore database equivalence remain unverified.
+- Documentation: `RENDER.md`, renderer-baseline procedure, coordinate-mapping
+  and world-renderer module API/input-output/data-flow/capability/source-map
+  sections updated. No lifecycle/state diagram changed because the verifier and
+  mapper path are synchronous; capture reuses the documented renderer lifecycle.
+- Recommended merge order: `318e6ae` after master merge `747fae8`. Then the M01
+  milestone integrator may accept all M01 claims, update target Evidence/checks
+  and evaluate `OPENWC_TARGET_DONE`.

+## Ownership
+
+- Target: M01
+- Program: RND/FND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m01-streaming-focus`
+- Lease expires UTC: 2026-07-15
+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Introduce a scene-free `StreamingFocus` value and make runtime/test streaming
+consume it through an explicit source or public setter instead of discovering
+the active `Camera3D` from a viewport.
+
+## Non-goals
+
+- Extracting `WorldRenderFacade` or `StreamingTargetPlanner` from the monolithic loader.
+- Adding direction, velocity, frustum or multi-focus planning.
+- Decomposing the player controller before M02.
+- Changing terrain, M2, WMO, liquid, cache or LOD formulas.
+
+## Paths
+
+- Exclusive: `src/domain/streaming/`, `src/tools/verify_streaming_focus.gd`
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,
+  `src/scenes/streaming/eastern_kingdoms_streaming.tscn`,
+  `src/scenes/streaming/kalimdor_streaming.tscn`, renderer diagnostic tools,
+  `docs/modules/world-renderer.md`, this claim
+- Generated/ignored: local extracted assets, renderer caches and Godot import metadata
+
+## Contracts and data
+
+- Public API: immutable `StreamingFocus`; loader `set_streaming_focus` and
+  `refresh_streaming_focus`
+- Source adapter: explicit `streaming_focus_source_path` may reference any `Node3D`
+- Migration: runtime scenes use player focus; capture/probe tools explicitly use
+  their dedicated camera as the source
+- Compatibility: streaming radii/LOD/cache behavior and coordinate contract v2 unchanged
+
+## Dependencies
+
+- Requires: coordinate contract version 2 and golden fixtures at `52e1b2b`
+- Blocks: M01 renderer/test focus exit criterion and later renderer facade extraction
+- External state: no new dependency or proprietary input
+
+## Verification
+
+- Commands: streaming focus contract/integration verifier, renderer baseline
+  manifest/calibration, headless scene smoke, coordination/documentation gates
+- Fixtures: Node3D player-style source and explicit capture-style setter
+- Fidelity evidence: existing seven renderer checkpoints and build-12340 coordinate
+  calibration must remain unchanged
+- Performance budget: one scalar focus snapshot per configured streaming interval;
+  no new per-tile or per-chunk work
+
+## Documentation deliverables
+
+- Inline public API docs: focus value and loader public methods
+- Module specification: inputs/outputs, ownership, lifecycle, failure/recovery and source map
+- Data-flow diagram: player/editor/capture source to focus contract to loader
+- State/sequence diagram: focus sampling and refresh threshold sequence
+
+## Simplicity and naming
+
+- Important names introduced: `StreamingFocus`, `streaming_focus_source_path`,
+  `set_streaming_focus`, `refresh_streaming_focus`
+- Simplest considered solution: one immutable value plus one explicit scene adapter path
+- Rejected complexity/abstractions: provider interface hierarchy, service locator,
+  multi-focus registry and predictive motion fields
+- Unavoidable complexity and justification: editor viewport remains a separate
+  adapter because its camera is owned by `EditorInterface`
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: contract, runtime/editor/capture migration, headless regression,
+  module diagrams, renderer documentation and cold/warm GUI capture
+- Next: integrator review and merge before typed identity work
+- Blocked by:
+
+## Handoff
+
+- Commit: `7815385`
+- Branch: `work/sindo-main-codex/m01-streaming-focus`
+- Outcome: runtime streaming consumes immutable `StreamingFocus`; Eastern
+  Kingdoms and Kalimdor scenes explicitly follow the player, while capture and
+  terrain/occluder probes explicitly follow their dedicated camera
+- Contract/API: new scene-free `StreamingFocus(GodotWorldPosition)` plus loader
+  `set_streaming_focus`, `refresh_streaming_focus` and
+  `streaming_focus_source_path`; `camera_path` remains only for optional overview positioning
+- Verification: StreamingFocus PASS (`1` contract, `2` runtime scenes, `3`
+  capture tools); coordinate golden fixtures and CoordinateMapper PASS; M00
+  calibration PASS with maximum error `0.000015`; manifest PASS (`7`
+  checkpoints); runtime-cache shutdown PASS; headless runtime scene exit `0`;
+  coordination, documentation, dependency and whitespace checks passed
+- Renderer checkpoint: standard 8-second GUI capture completed `14` images
+  (`7` cold + `7` warm) and wrote schema-1 `report.json`; focus tiles changed
+  through the public contract; no Node/resource/RID leak diagnostic appeared
+- Fidelity: checkpoint camera positions, coordinate contract v2, streaming radii,
+  LOD formulas, cache formats and quality profiles are unchanged; this is
+  regression evidence, not a new `1:1` parity claim
+- Rebuild: none; GUI verification used local ignored extracted assets/cache
+  junctions. Missing worktree `.godot/imported` copies for several incidental M2
+  GLBs produced existing cache-load fallback diagnostics only
+- Remaining risks: the monolithic loader still owns planning/jobs/presentation;
+  direction, velocity, frustum and multiple foci remain M03 planner work. The
+  known timing-dependent zero-reference `ObjectDB` shutdown warning occurred,
+  without Node/resource/RID leak diagnostics
+- Recommended merge order: after coordinate fixtures at `52e1b2b`, before typed
+  identity and renderer-facade extraction
+- Documentation: `world-renderer.md` inputs/outputs, public API, lifecycle,
+  data-flow and sequence diagrams, ownership, recovery, verification,
+  capability matrix, risks and source map updated; `RENDER.md` updated

+
+## Dependencies

+- Requires: merged M01 coordinate/streaming-focus contracts on master `62eece9`

+- External state: none; tests use synthetic Input Map events
+
+## Verification

+- Fixtures: synthetic action strengths and configured default bindings
+- Fidelity evidence: current W/S/A/D, Shift, E/Q and Space sandbox behavior remains

+- Unavoidable complexity: none
+- Measured optimization evidence: not applicable

+## Status

+- State: ready-for-review
+- Done: twelve remappable actions, immutable `MoveIntent`, stateless

+- Blocked by:
+
+## Handoff
+
+- Commit: `6bd2e84`
+- Branch: `work/sindo-main-codex/m02-player-input`
+- Outcome: the runtime player no longer polls physical keyboard keys. Movement
+  action strengths cross an immutable `MoveIntent` seam; camera and immediate
+  sandbox-flight events use the same remappable action catalog.
+- Public contract: additive `MoveIntent`, `PlayerInputActions` and
+  `PlayerInputSource`; no schema, cache, coordinate or renderer contract change.
+- Verification: `PLAYER_INPUT PASS actions=12 intent_cases=6 controller=1
+  regression_scene=1`; asset-free scene smoke exited `0`; coordinate boundary
+  (`88` files) and StreamingFocus gates passed; unified renderer dry-run passed
+  all eight pre-capture gates and produced seven dry-run checkpoint results;
+  coordination/documentation/diff gates passed.
+- Fidelity: W/S/A/D, Shift, E/Q, Space, right mouse, wheel and Escape remain the
+  default sandbox bindings. Regression drives forward movement, camera zoom and
+  immediate flight toggle through the real controller. This does not establish
+  exact build-12340 default bindings, turn/strafe policy or gameplay movement parity.
+- Local verification inputs: the isolated worktree reused the existing ignored
+  native DLL and generated ADT resource scripts. Proprietary extracted data and
+  the character GLB were absent, so the renderer dry-run logged the expected
+  missing-corpus diagnostics while all contract steps returned success.
+- Rebuild/migration: none. Action names are additive; persisted user-binding
+  migration does not exist yet and is documented as a gap.
+- Remaining risks: production profile gating for sprint/free flight, exact
+  3.3.5a bindings, local movement/terrain/camera/presentation extraction and
+  broader movement/camera state tests remain M02 work.
+- Documentation: inline API comments plus `docs/modules/player-input.md` with
+  inputs/outputs, data-flow and sequence diagrams, ownership, recovery,
+  capability status, known gaps and source map.

+
+## Outcome
+
+Add a profile-aware, remappable `Blizzlike335` input path whose default movement
+bindings match the extracted build-12340 binding table while preserving the
+existing `RenderSandbox` controls. Add deterministic turn intent and keyboard
+turn consumption at the server-contract default turn rate.

+- Claim complete movement or camera parity from binding and turn-rate evidence.

+- Generated/ignored: local `.godot`, native DLL and proprietary extracted corpus
+
+## Contracts and data
+
+- `MoveIntent` gains an immutable, clamped signed turn axis.
+- `PlayerInputSource` selects explicit sandbox or compatibility action sets at
+  construction and routes compatibility A/D to strafe while camera rotation is held.
+- `LocalPlayerMovementController` converts turn intent into a deterministic yaw
+  delta without reading engine input or owning a scene transform.
+- A sanitized JSON fixture records selected binding facts, source hashes and the
+  pinned TrinityCore 3.3.5 server-contract commit.
+
+## Dependencies
+
+- Requires: merged sandbox capability package on master `c3094c9`.
+- Blocks: final M02 integration audit and milestone closeout.
+- External state: local extracted build-12340 binding files are evidence inputs
+  only; committed tests are reproducible without them.
+
+## Verification
+
+- Fixture schema/provenance and selected default-binding regression.
+- Pure profile composition, A/D turn, Q/E strafe and camera-held A/D strafe cases.
+- Deterministic turn-rate and controller integration regression.
+- Existing M02 and repository gates remain required.
+
+## Documentation deliverables
+
+- Updated input/movement public API, profile matrix, data flow, sequence,
+  failure/recovery, fidelity provenance and source maps.
+
+## Simplicity and naming
+
+- Important names: `turn_axis`, `BLIZZLIKE_STRAFE_LEFT`, `TURN_LEFT`.
+- Simplest approach: one profile selection at composition plus one scalar intent.
+- Rejected complexity: input-context framework, command bus and persisted binding store.
+- Unavoidable complexity: compatibility A/D behavior depends on camera-rotate state.
+- Measured optimization evidence: not applicable.
+
+## Status
+
+- State: ready-for-review

+  camera-yaw synchronization, sanitized provenance fixture, regression coverage
+  and updated module specifications

+
+## Handoff
+
+- Branch/commit: `work/sindo-main-codex/m02-input-profile-335` at `8776a6b`.
+- Outcome: `RenderSandbox` retains A/D strafe and debug E/Q/Space/Shift behavior;
+  `Blizzlike335` now samples W/S and Up/Down forward/back, Q/E strafe, A/D and
+  Left/Right turn, with A/D routed to strafe while right-mouse rotation is active.
+- Public contracts: `MoveIntent.turn_axis`; profile-selecting
+  `PlayerInputSource.new(profile_id)`; pure compatibility composition;
+  `LocalPlayerMovementController.calculate_yaw_delta_radians(...)`; camera yaw
+  synchronization after keyboard turn. Unknown input profiles fail closed to
+  `Blizzlike335`.
+- Project configuration: four additive compatibility actions; existing action
+  names and sandbox mappings remain valid. W/S also gain the original Up/Down
+  secondary defaults.
+- Verification: player input `actions=16 intent_cases=9 profiles=3 fixture=1
+  controller=1 regression_scene=3`; movement `cases=15 state_transitions=2`;
+  capabilities `profiles=3 sprint=2 flight=2 scenes=2`; terrain
+  `contract=4 interpolation=1 cache=1 failures=2`; camera
+  `state_cases=12 policy_cases=3`; presentation `appearance_cases=9
+  animation_cases=10`; coordinate boundaries `files=101`; StreamingFocus
+  `runtime_scenes=2 capture_tools=3`.
+- Renderer: unified dry-run passed project/material/dedupe/cache/manifest/
+  calibration/coordinate/server-spawn gates and planned all seven checkpoints;
+  coordinate gate reported `files=103`. Missing proprietary GLB/DBC/ADT inputs
+  produced the expected diagnostics only.
+- Repository gates: documentation `module_specs=8`; coordination
+  `fallback_claims=31`, with the same five unrelated expired M00 warnings.
+- Fidelity: local build-12340 `DefaultBindings.wtf` SHA-256
+  `35FFA0E4E2356A13A0633A848F9E57ABE7DF9D8A16C2245E15D33013AD2F56A5`
+  and `Bindings.xml` SHA-256
+  `2E01276AFB7462F1417710F13B4BF1A456341F7F28CC8AE0D6D9C7442D7F6793`
+  were rechecked and selected facts sanitized into the committed fixture.
+  TrinityCore revision `2853a621d6af91a803787a2b8a509f4ce3e0300d` supplies the
+  3.141594 rad/s player server-contract turn rate. WoWee revision
+  `626243e937fb93965fa583a6507ed5a1aa7dda4b` supports right-mouse A/D routing.
+- Fidelity limits: server turn rate and public reference routing are not direct
+  original-client timing/behavior proof. Jump, autorun and left-button
+  camera/select defaults are recorded but not implemented. This package does
+  not claim complete input, movement or camera parity.
+- Migration/cache: no persisted settings or cache schema. Future saved bindings
+  must migrate stable action names; current project users receive additive actions.
+- Documentation: updated input, movement and camera APIs, inputs/outputs, data
+  flow, sequence, ownership, failure/recovery, configuration, fidelity and source maps.
+- Recommended merge order: merge after sandbox capabilities (already on master),
+  then run the final M02 integration/evidence audit without marking the target
+  done solely from this package.

+## Handoff
+
+- Commit: `435e1c9`
+- Branch: `work/sindo-main-codex/m02-local-movement`
+- Outcome: `ThirdPersonWowController` no longer owns velocity, flight state,
+  acceleration or directional speed calculation. It selects an explicit
+  Godot-world basis, applies returned displacement, and retains terrain and
+  presentation adapters for later M02 packages.
+- Public contract: additive `LocalPlayerMovementController` with read-only
+  Godot-world velocity/flight state, `toggle_sandbox_flight` and `advance`.
+  Input, coordinate, cache and renderer contracts remain unchanged.
+- Verification: `LOCAL_PLAYER_MOVEMENT PASS cases=12 state_transitions=2
+  scene_boundary=1`; `PLAYER_INPUT PASS actions=12 intent_cases=6 controller=1
+  regression_scene=1`; asset-free scene smoke exited `0`; coordinate boundary
+  and StreamingFocus passed; renderer dry-run passed all eight pre-capture gates
+  and seven checkpoint plans; coordination/documentation/diff gates passed.
+- Fidelity: exact existing defaults are regression-locked—forward `7.0`,
+  backward/strafe `4.5`, acceleration `28.0`, sandbox sprint `6x`, vertical
+  flight `7.0`, velocity reset on toggle and camera-relative pitched flight.
+  This preserves the sandbox baseline but is not original-client evidence.
+- Local verification inputs: the isolated worktree reused the existing ignored
+  native DLL and generated ADT resource scripts. Proprietary extracted data and
+  character GLB were absent, so renderer dry-run logged expected missing-corpus

+- Lease expires UTC: 2026-07-16
+- Integrator: M02 milestone integrator
+
+## Outcome
+
+Introduce an immutable local-player movement capability contract and require it
+at the movement boundary so debug sprint and free flight execute only in the
+explicit `RenderSandbox` profile and are rejected by `Blizzlike335`.
+
+## Non-goals
+
+- Claim that current movement values or `Blizzlike335` locomotion are 1:1.
+- Build a global application/profile framework before the application shell exists.

+  `docs/modules/player-input.md`
+- Generated/ignored: local `.godot`, native DLL, generated resources and renderer corpus
+
+## Contracts and data
+
+- `PlayerMovementCapabilities` owns immutable profile ID plus explicit debug
+  sprint/flight booleans and safe named factories.
+- `LocalPlayerMovementController` requires the capability value; missing input
+  falls back to `Blizzlike335`, never sandbox.
+- Player scene maps its exported profile selection once at the composition boundary.
+- Input actions and `MoveIntent` remain unchanged; rejected debug requests have no effect.
+
+## Dependencies
+
+- Requires: merged character presentation package on master `8c71e46`.
+- Blocks: final M02 integration audit and milestone closeout.
+- External state: none; verification is asset-free.

+## Verification
+
+- Pure profile factory/default and immutability regression.
+- Sprint accepted in RenderSandbox and ignored in Blizzlike335.
+- Flight toggle/vertical basis accepted in RenderSandbox and rejected in Blizzlike335.
+- Real regression scene verifies both profile compositions.
+- Existing input/movement/terrain/camera/presentation and renderer gates remain required.
+- Fidelity evidence: negative proof that debug capabilities cannot affect the
+  compatibility profile; no positive movement parity claim.
+
+## Documentation deliverables
+
+- Inline public API and profile semantics on the capability/controller boundary.
+- Updated movement and input specs: API, inputs/outputs, data flow, lifecycle,
+  failure/recovery, capability matrix and source map.
+
+## Simplicity and naming
+
+- Important name: `PlayerMovementCapabilities`.
+- Simplest approach: one immutable value injected into the existing controller.
+- Rejected complexity: autoload singleton, generic feature-flag service and global profile registry.
+- Unavoidable complexity: one profile-to-capability mapping at scene composition.
+- Measured optimization evidence: not applicable.
+
+## Status
+
+- State: ready-for-review
+- Done: added immutable capability contract, gated sprint/free-flight, covered
+  pure and real-scene profiles and updated movement/input specifications
+- Next: milestone integrator reviews and merges `742c415`

+
+## Handoff
+
+- Branch/commit: `work/sindo-main-codex/m02-sandbox-capabilities` at `742c415`.
+- Outcome: debug sprint and free flight now require explicit
+  `PlayerMovementCapabilities.render_sandbox()`; `Blizzlike335`, unknown and
+  null capability inputs reject both effects.
+- Public contract: immutable profile ID plus `allows_debug_sprint` and
+  `allows_debug_free_flight`; named factories map configuration once at the
+  composition boundary. The movement controller exposes its effective profile ID.
+- Runtime composition: `ThirdPersonWowController.movement_profile_id` defaults
+  to `RenderSandbox`, preserving renderer-scene behavior. Selecting
+  `Blizzlike335` keeps ordinary movement while ignoring Shift/Space/E/Q effects.
+- Verification: capability `profiles=3 sprint=2 flight=2 scenes=2 boundary=1`,
+  movement `cases=12 state_transitions=2`, input `actions=12 intent_cases=6`,
+  terrain `contract=4 interpolation=1 cache=1 failures=2`, camera
+  `state_cases=12 policy_cases=3`, presentation
+  `appearance_cases=9 animation_cases=10`, coordinate boundaries
+  `files=101 consumers=5`, and StreamingFocus `runtime_scenes=2 capture_tools=3` passed.
+- Renderer: dry-run passed project/material/dedupe/cache/manifest/calibration/
+  coordinate/server-spawn gates and planned all seven checkpoints; the combined
+  run reported coordinate `files=103`. Missing proprietary GLB/DBC/ADT inputs
+  produced the expected diagnostics only.
+- Repository gates: documentation `module_specs=8`, coordination
+  `fallback_claims=30`; five unrelated expired M00 claim warnings remain.
+- Fidelity: this package provides negative evidence that sandbox-only debug
+  movement cannot alter the `Blizzlike335` profile. It does not prove ordinary
+  movement, bindings, flight or timing match build 12340.
+- Migration: direct `LocalPlayerMovementController.new(...)` callers that need
+  debug behavior must now pass `render_sandbox()`; omitted/null capability is
+  intentionally compatibility-safe. Existing repository scenes require no edit.
+- Cache/persistence: no schema, cache, binding or stored-profile migration.
+- Local ignored inputs: native extension DLL, UID cache and generated ADT
+  resource scripts supported renderer verification and are not committed.
+- Risks: runtime renderer scenes still default to `RenderSandbox`; the future
+  application shell must explicitly choose its profile. `Blizzlike335` currently
+  guarantees only debug exclusion, not complete movement fidelity.
+- Recommended merge order: merge after presentation (already on master), then
+  perform the final M02 integration/evidence audit before any target closeout.
+- Documentation: updated movement/input API, inputs/outputs, data flow, state,
+  sequence, ownership, failure/recovery, capabilities, verification and source maps.

+- Branch: `work/sindo-main-codex/m02-terrain-query`
+- Lease expires UTC: 2026-07-16
+- Integrator: M02 milestone integrator
+
+## Outcome
+
+Introduce a typed `TerrainQuery` boundary and move ADT loading, caching, chunk
+selection and height interpolation out of `ThirdPersonWowController` without
+changing current spawn/ground-snap behavior.
+
+## Non-goals
+
+- Change ADT topology, coordinate formulas, terrain mesh or renderer caches.
+- Add physics collision, slopes, water, jump/fall/swim or server movement.
+- Reuse the streaming renderer cache before its public terrain-query contract exists.
+- Extract camera or character presentation.
+- Mark M02 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/gameplay/terrain/`, `src/tools/verify_terrain_query.gd`,
+  `docs/modules/terrain-query.md`, this claim
+- Shared/hotspots: `src/scenes/player/third_person_wow_controller.gd`,

+  `docs/modules/local-player-movement.md`,
+  `docs/modules/README.md`
+- Generated/ignored: local `.godot`, native DLL, generated ADT resources and renderer corpus
+
+## Contracts and data
+
+- Public API: `TerrainQuery.sample_ground_height(GodotWorldPosition)` returning
+  immutable `TerrainGroundSample`
+- Production adapter: `AdtTerrainQuery` with owned per-tile parse cache
+- Test/data-source seam: optional ADT tile loader callable at construction
+- Coordinate contract version, ADT format, renderer cache and persistence: unchanged
+- Consumers: current player scene; future movement/collision policies
+
+## Dependencies
+
+- Requires: merged movement controller on master `5206c42`
+- Blocks: camera/presentation extraction from the player hotspot
+- External state: production uses existing native `ADTLoader`; synthetic tests need no proprietary data
+
+## Verification
+
+- Commands: synthetic height/cache/failure verifier, player input/movement
+  regressions, asset-free scene, coordinate/StreamingFocus gates, renderer dry-run
+  and repository gates
+- Fixtures: synthetic 145-height chunk payload and injected flat terrain query
+- Fidelity evidence: preserves existing outer-grid bilinear interpolation,
+  spawn ground offset and per-tick snap formula only
+- Performance budget: one cached tile lookup and local interpolation per ground query;
+  no new I/O after first tile load
+
+## Documentation deliverables
+
+- Inline public API docs for query, sample and ADT adapter
+- Terrain-query module spec with inputs/outputs, data-flow, cache lifecycle and sequence diagrams
+- Updated movement/coordinate consumer boundaries, source maps and module registry
+
+## Simplicity and naming
+
+- Important names: `TerrainQuery`, `TerrainGroundSample`, `AdtTerrainQuery`
+- Simplest approach: one narrow query contract, one typed result and one existing-format adapter
+- Rejected complexity: general collision framework, terrain service locator and renderer-cache coupling
+- Unavoidable complexity: ADT 145-height layout and chunk lookup stay isolated in adapter
+- Measured optimization evidence: existing per-tile cache retained; no new optimization
+
+## Status
+
+- State: ready-for-review
+- Done: typed query/sample contract, cached ADT adapter, player migration,
+  synthetic interpolation/cache/failure tests, injected scene regression and documentation
+- Next: M02 integrator reviews and merges before camera-rig extraction
+- Blocked by:
+
+## Handoff
+
+- Commit: `a45d521`
+- Branch: `work/sindo-main-codex/m02-terrain-query`
+- Outcome: `ThirdPersonWowController` no longer loads ADTs, caches tile
+  dictionaries, selects chunks or interpolates height grids. It consumes a
+  replaceable typed `TerrainQuery` and retains only existing offset/snap policy.
+- Public contracts: additive immutable `TerrainGroundSample`, replaceable
+  `TerrainQuery`, cached `AdtTerrainQuery` and player `set_terrain_query`.
+  Coordinate contract version, ADT/native format and renderer caches are unchanged.
+- Verification: `TERRAIN_QUERY PASS contract=4 interpolation=1 cache=1
+  failures=2 player_injection=1`; player-input and local-movement regressions
+  passed; asset-free scene exited `0`; coordinate boundary passed with five
+  required consumers and StreamingFocus passed; renderer dry-run passed eight
+  pre-capture gates and seven checkpoint plans; coordination/documentation/diff gates passed.
+- Fidelity: synthetic fractional-grid fixture locks the inherited 145-height
+  outer-grid bilinear result within `0.002` Godot units; injected scene locks
+  spawn offset `0.05` and physics snap. This is sandbox-regression evidence,
+  not build-12340 triangle/hole/collision parity.
+- Local verification inputs: isolated worktree reused the existing ignored
+  native DLL and generated ADT resource scripts. Proprietary extracted data and
+  character GLB were absent, so renderer dry-run logged expected missing-corpus
+  diagnostics while all contract steps returned success.
+- Rebuild/migration: none; caches are transient and existing formats remain unchanged.
+- Remaining risks: first ADT parse remains synchronous as before; unavailable
+  tiles cache until query replacement; player still owns snap policy; exact
+  ADT triangle choice, holes, slopes, liquids and collision remain open.
+- Documentation: inline public APIs plus `docs/modules/terrain-query.md` with
+  inputs/outputs, data-flow, cache state and cross-boundary sequence diagrams,
+  ownership, failure/recovery, capability status and source map. Coordinate and
+  movement consumer specifications were updated.

+
+## Outcome
+
+Audit every merged M02 package on current master, record final structural and

+gates pass.
+
+## Non-goals
+
+- Change player, movement, terrain, camera, presentation or renderer behavior.
+- Claim complete WoW 3.3.5a locomotion/camera parity.
+- Implement recorded jump/fall/swim/fly, collision or timing gaps.
+- Commit proprietary assets, generated UIDs, caches or user scene changes.
+
+## Paths

+
+## Dependencies

+
+## Handoff
+
+- Commit: `1bf5b52`.
+- Branch: `work/sindo-main-codex/m02-integrator-closeout`.
+- Outcome: M02 is `DONE` with all eight structural checklist items and complete
+  classified Evidence; M03 is the only `ACTIVE` target and the target index/
+  roadmap point to renderer-facade extraction.
+- Integration audit: all seven READY implementation commits are ancestors of
+  merged master `eb122d5`; their claims now carry the corresponding
+  `OPENWC_INTEGRATION:ACCEPTED` merge markers.
+- Verification: input `16/9/3/1/3`, movement `15` cases and `2` transitions,
+  capability `3` profiles and `2` scenes, terrain `4/1/1/2`, camera `12/3`,
+  presentation `9/10/3`, coordinate boundaries `103` files and StreamingFocus
+  `2` runtime scenes/`3` capture tools all passed. Unified renderer dry-run
+  passed project/material/dedupe/shutdown gates, manifest `7/7/7`, calibration
+  maximum error `0.000015`, server-spawn renderer and seven checkpoint plans.
+- Repository gates: documentation passed with `8` module specs and `7` required
+  files. Coordination passed with one active target; `13` expired M00 claim
+  warnings are historical and unrelated to M02.
+- Fidelity: direct build-12340 binding hashes/facts are preserved in the
+  sanitized fixture. TrinityCore turn rate and WoWee mouse routing remain
+  explicitly reference-only. Translation speeds/camera values are sandbox
+  regressions, and jump/fall/swim/fly parity remains unimplemented/unverified.
+  Debug sprint/free flight is negatively proven absent from `Blizzlike335`.
+- Remaining risks: target Evidence carries exact follow-up scope for M09/M10/M12:
+  movement/camera timing, jump/fall/swim/fly, autorun/LMB semantics, active
+  collision, terrain/liquid policy, persisted bindings, server authority and
+  prediction/reconciliation. No complete `1:1` claim is made.
+- Runtime/cache/migration: no behavioral change, dependency, cache schema or
+  persisted settings migration in closeout.
+- Documentation: M02 target Evidence/checklist, seven acceptance markers,
+  target index and roadmap state updated. Existing input, movement, terrain,
+  camera and presentation API/module specs and diagrams passed the documentation gate.

+
+## Non-goals
+
+- Enable a new collision/raycast behavior before build-12340 comparison.
+- Change initial yaw/pitch, zoom limits, sensitivity, FOV, far plane or camera path.
+- Implement first-person, follow lag, shoulder offsets or cinematic cameras.

+  `NoCameraCollisionPolicy` returns requested distance unchanged
+- Scene paths and renderer camera path remain unchanged
+- Schema/cache/coordinate contracts: unchanged
+- Consumers: player composition, sandbox flight movement and renderer viewport
+
+## Dependencies
+
+- Requires: merged TerrainQuery package on master `f5bb64e`
+- Blocks: character appearance/animation extraction from remaining player hotspot
+- External state: none; tests use asset-free camera/player scene

+- Commands: dedicated orbit/zoom/clamp/policy verifier, input/movement/terrain
+  regressions, asset-free scene, coordinate/StreamingFocus gates, renderer dry-run
+  and repository gates
+- Fixtures: initial state, remappable action events, mouse deltas and fixed-distance policy
+- Fidelity evidence: preserve current `-18°` pitch, `8` distance, `1` zoom step,
+  `2..18` clamp, `0.003` sensitivity and no-collision output
+- Performance budget: constant-time state/transform update; no raycast in baseline policy
+
+## Documentation deliverables
+
+- Inline API/export documentation for rig and collision policies
+- Camera module spec with inputs/outputs, data-flow, state and sequence diagrams
+- Updated input/movement consumer diagrams/source maps and module registry
+
+## Simplicity and naming

+
+## Status

+
+## Handoff
+
+- Outcome: `ThirdPersonCameraRig` now owns capture, orbit, zoom and camera
+  transforms; `ThirdPersonWowController` only dispatches camera events and
+  consumes the rig basis for sandbox flight.
+- Public contracts: `initialize_for_character`, `handle_camera_input`,
+  `godot_world_flight_movement_basis`, `set_collision_policy`, read-only state,
+  and `CameraCollisionPolicy.resolve_camera_distance`.
+- Verification: camera `state_cases=12 policy_cases=3 scenes=3`, input
+  `actions=12 intent_cases=6`, movement `cases=12 state_transitions=2`, terrain
+  `contract=4 interpolation=1 cache=1 failures=2`, coordinate boundary
+  `files=98 consumers=5`; documentation, coordination and diff checks passed.
+- Renderer dry-run: seven checkpoint plans and report completed; expected
+  diagnostics only for unavailable proprietary corpus/character GLB.
+- Fidelity: preserves the sandbox defaults (`-18 degrees`, distance `8`, zoom
+  `2..18` step `1`, sensitivity `0.003`, pivot `1.7`, far `50000`) and the prior
+  no-collision behavior. No build-12340 parity claim is made.
+- Local ignored inputs: native extension DLL and generated ADT resource scripts
+  were used for the renderer dry-run and are not part of the commit.
+- Migration: none; `ThirdPersonPlayer/CameraPivot/Camera3D` remains stable.
+- Risks: active collision and exact original-client camera semantics remain
+  unverified; exported initial values are captured at ready; mouse mode is
+  process-global.
+- Documentation: added the camera API/module spec plus data-flow, state and
+  sequence diagrams; updated player-input and local-movement consumer maps.

+- Reused unchanged: geoset controller, texture compositor and outfit resolver
+- Generated/ignored: local `.godot`, native DLL, generated resources and renderer corpus
+
+## Contracts and data
+
+- Appearance API loads/replaces one character root under the existing `Visual` node.
+- Animation API binds an `AnimationPlayer` from that root and accepts a typed
+  moving/stationary presentation state.
+- Scene paths, model defaults, DBC/cache/coordinate contracts remain unchanged.
+- Consumers: player scene composition and renderer viewport only.
+
+## Dependencies
+
+- Requires: merged camera package on master `68e6f60`.
+- Blocks: final M02 sandbox-profile gate and target integration audit.
+- External state: asset-free tests use a synthetic mesh and AnimationPlayer.
+
+## Verification
+
+- Dedicated appearance composition, replacement, grounding and failure regression.
+- Dedicated animation discovery, fallback, looping, blend and state regression.
+- Player source-boundary and three-scene wiring checks.
+- Existing input/movement/terrain/camera regressions, coordinate gates and renderer dry-run.
+- Fidelity evidence: preserve current sandbox model path, scale, yaw, outfit,
+  Stand/Idle and Run/Walk selection only; no original-client parity claim.
+
+## Documentation deliverables
+
+- Inline public API/export documentation for both presenters.
+- Module specification with inputs/outputs, data-flow, lifecycle/state and sequence diagrams.
+- Updated movement consumer/source map and module registry.
+
+## Simplicity and naming
+
+- Important names: `CharacterAppearancePresenter`, `CharacterAnimationPresenter`.
+- Simplest approach: two small scene components on the existing `Visual` subtree.
+- Rejected complexity: generic presenter framework, async asset scheduler and duplicated character systems.
+- Unavoidable complexity: scene-tree composition and AnimationPlayer discovery run on the main thread.
+- Measured optimization evidence: not applicable.
+
+## Status
+
+- State: ready-for-review
+- Done: extracted both presenters, migrated all runtime/regression scenes,
+  added asset-free regressions and completed required module documentation
+- Next: milestone integrator reviews and merges `97bb53f`
+- Blocked by:

+
+## Handoff
+
+- Branch/commit: `work/sindo-main-codex/m02-character-presentation` at `97bb53f`.
+- Outcome: `CharacterAppearancePresenter` owns model/geoset/compositor/outfit
+  composition and `CharacterAnimationPresenter` owns AnimationPlayer discovery,
+  loop preparation and moving/stationary playback. The player is now only the
+  composition and horizontal-velocity adapter.
+- Changed composition: both runtime scenes and the player regression scene keep
+  `ThirdPersonPlayer/Visual`; they add `Visual/AnimationPresenter`.
+- Public contracts: appearance load/read-root/ready signal and animation
+  bind/present/read-state APIs documented in the module specification.
+- Verification: presentation `appearance_cases=9 animation_cases=10 scenes=3`,
+  input `actions=12 intent_cases=6`, movement `cases=12 state_transitions=2`,
+  terrain `contract=4 interpolation=1 cache=1 failures=2`, camera
+  `state_cases=12 policy_cases=3`, coordinate boundaries `files=99 consumers=5`,
+  and StreamingFocus `runtime_scenes=2 capture_tools=3` passed.
+- Renderer: dry-run passed project/material/dedupe/cache/manifest/calibration/
+  coordinate/server-spawn gates and planned all seven checkpoints. Missing
+  proprietary HumanMale GLB, DBC and ADT corpus produced expected diagnostics.
+- Repository gates: documentation `module_specs=8`, coordination
+  `fallback_claims=29`; five unrelated expired M00 claim warnings remain.
+- Fidelity: current model path, scale `1`, yaw `90 degrees`, class `1`, blend
+  `0.15 seconds`, starter outfit and Stand/Idle/Run/Walk selection are preserved.
+  No build-12340 appearance or animation parity claim is made.
+- Migration: repository scenes are migrated. External/custom scenes must move
+  model/class/scale/yaw exports from the player node to the scripted `Visual`
+  node and add `Visual/AnimationPresenter`. No cache/database rebuild is needed.
+- Local ignored inputs: native extension DLL, UID cache and generated ADT
+  resource scripts supported the dry-run and are not committed.
+- Risks: synchronous model load may hitch; first descendant AnimationPlayer wins;
+  moving state is a sandbox threshold boolean; complete equipment/animation
+  fidelity remains open.
+- Recommended merge order: merge this package after camera (already on master),
+  then implement the sandbox profile gate and perform the final M02 integration audit.
+- Documentation: added character-presentation API, inputs/outputs, data-flow,
+  lifecycle/state, sequence, ownership/failure and source-map sections; updated
+  the module registry and movement presentation consumer map.

+## Outcome
+
+Extract ADT water pending-request FIFO/deduplication, active worker task IDs and
+worker-safe result mailbox from the loader while preserving loader-owned parse,
+budget, stale-result and scene finalization behavior.
+
+## Non-goals
+
+- Instantiate `ADTLoader`, start/wait WorkerThreadPool tasks or parse ADT bytes.
+- Consume `WATER_FINALIZE` permits or choose concurrency/profile limits.
+- Build/attach/free water Nodes, materials, Meshes or RIDs.
+- Change tile/path stale checks, empty-data behavior or `water_loaded` timing.
+- Change MH2O/MCLQ parsing or claim liquid fidelity/performance parity.

+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated ADT resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Pending requests preserve FIFO and tile-key deduplication.
+- Tile release removes all matching pending entries but does not cancel active work.
+- Active task IDs are loader-created opaque integers keyed by tile.
+- Worker publication and main-thread result pop/clear are mutex protected.
+- Result order and Dictionary payload identity remain unchanged.
+- Clear releases bookkeeping only; loader waits tasks at orderly shutdown.
+- Water parsing, coordinate, material, profile and visual rules are unchanged.
+
+## Dependencies
+
+- Requires: current master `4387c66`; accepted scheduler and renderer lifecycle
+- Blocks: further liquid parse/finalization decomposition
+- External state: none; verification uses synthetic task IDs and payloads
+
+## Verification
+
+- Commands: dedicated FIFO/dedupe/task/result/cancel/clear/thread/source/timing
+  verifier; shutdown, water/material and adjacent renderer/streaming/coordinate/
+  documentation/coordination gates
+- Fixtures: synthetic tile/path requests, task IDs and water dictionaries
+- Fidelity evidence: exact current queue/task/result transitions preserved
+- Performance budget: 100 cycles over 256 requests/results under 1 second
+
+## Documentation deliverables
+
+- Inline public API docs
+- Module specification with inputs/outputs, ownership and source map
+- Data-flow, lifecycle/state, worker sequence and dependency diagrams
+- World-renderer, module registry and RENDER status updates
+
+## Simplicity and naming

+- Important names introduced: `AdtWaterLoadPipelineState`
+- Simplest considered solution: one RefCounted with FIFO/dedupe/task maps and one mutex mailbox
+- Rejected complexity/abstractions: generic async scheduler, signals, callbacks,
+  WorkerThreadPool wrapper, parser/material ownership or multi-lane framework
+- Unavoidable complexity and justification: result mailbox crosses worker/main threads
+- Measured optimization evidence: bounded synthetic lifecycle loop

+
+## Outcome
+
+Extract main-thread ADT water subtree construction, tile-root attachment and
+optional recursive editor ownership from `StreamingWorldLoader` while retaining
+the existing `ADTBuilder` geometry/material implementation.
+
+## Non-goals
+
+- Parse or reinterpret MH2O/MCLQ data.
+- Own pending requests, WorkerThreadPool tasks or parsed-result delivery.
+- Consume `WATER_FINALIZE` permits or validate tile/path/result staleness.
+- Mark tile state `water_loaded` or choose whether water is enabled.
+- Change liquid geometry, materials, coordinates, cache formats or profiles.
+
+## Paths

+- Generated/ignored: `.godot`, native DLL, generated ADT resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Empty water data or invalid tile root produces no Node and no scene mutation.
+- Existing `ADTBuilder.build_tile_water_scene` remains the only geometry/material source.
+- A non-empty built Water root is attached exactly once to the supplied tile root.
+- Optional editor ownership is assigned recursively only when explicitly enabled
+  and an edited scene root is available.
+- The returned Node is borrowed and remains owned by the tile SceneTree subtree.
+
+## Dependencies
+
+- Requires: accepted water pipeline package on current master `e1b2886`
+- Blocks: further liquid finalization/material responsibility extraction
+- External state: none; verification uses synthetic liquid dictionaries
+
+## Verification
+
+- Commands: dedicated empty/invalid/build/attach/editor-owner/source/timing
+  verifier; water pipeline, materials, shutdown, facade, internal-access,
+  manifest, documentation and coordination gates
+- Fixtures: synthetic one-cell liquid mask/heights and temporary Node roots
+- Fidelity evidence: exact existing ADTBuilder output and two attachment paths preserved
+- Performance budget: 100 empty finalization attempts under 1 second
+
+## Documentation deliverables
+
+- Inline public API docs
+- Module specification with inputs/outputs, ownership and source map
+- Data-flow, lifecycle/state, main-thread sequence and dependency diagrams
+- Water-pipeline, world-renderer, module registry and RENDER status updates

+  require recursive owner assignment after SceneTree attachment
+- Measured optimization evidence: bounded synthetic no-water loop
+
+## Status

+## Handoff
+
+- Commit: `235be3a`
+- Results: scene finalizer PASS (`cases=8`, `iterations=100`,
+  `elapsed_ms=0.042`; initial `0.024ms`); synthetic liquid produced one
+  four-vertex/six-index surface with tile attachment and recursive owner; water
+  pipeline (`119.648ms`), WMO/M2/terrain/facade/scheduler/streaming/coordinate,
+  materials, shutdown, internal-access `36` and 32 headless contract regressions
+  PASS; documentation and coordination gates PASS; checkpoint dry-run PASS `7/7`.
+- Remaining risks: main-thread mesh/material construction remains synchronous
+  behind one existing permit; the Dictionary builder boundary remains untyped;
+  proprietary MH2O/MCLQ traversal/leak/p95/p99/original-client evidence is absent.
+  A verifier launched concurrently with the initial cold editor import observed
+  the pre-existing global-class cache race; serialized editor parse and shutdown
+  rerun passed, with only expected missing private asset diagnostics.
+- Documentation updated: inline public API; new
+  `docs/modules/adt-water-scene-finalizer.md`; water-pipeline spec, module registry,
+  world renderer and `RENDER.md`; data-flow/state/sequence/dependency diagrams,

+- Branch: `work/sindo-main-codex/m03-renderer-facade`
+- Lease expires UTC: 2026-07-17
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Introduce `WorldRenderFacade` as the only runtime/tool caller surface for typed
+streaming focus updates and read-only renderer metrics, while retaining
+`StreamingWorldLoader` as the unchanged internal implementation.
+
+## Non-goals
+
+- Extract the pure target planner or budget scheduler in this package.
+- Add environment or entity-presentation commands before their contracts exist.
+- Replace the M02 `TerrainQuery` gameplay boundary in this package.
+- Change streaming radii, queues, cache formats, visuals or quality presets.
+- Mark M03 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/render/world_render_facade.gd`,
+  `src/tools/verify_world_render_facade.gd`, this claim
+- Shared/hotspots: both runtime streaming scenes, three renderer capture/probe
+  tools, `src/tools/verify_streaming_focus.gd`, `docs/modules/world-renderer.md`,
+  `docs/modules/README.md`, `RENDER.md`
+- Generated/ignored: local `.godot`, native build outputs, caches and proprietary
+  renderer corpus
+
+## Contracts and data
+
+- Public API: `set_streaming_focus`, `refresh_streaming_focus`,
+  `renderer_metrics_snapshot`
+- Scene adapter: explicit `streaming_focus_source_path` owned by the facade
+- Internal implementation seam: `streaming_world_loader_path`; callers must not
+  read streamer queues or call its methods directly
+- Schema/cache/coordinate contracts: unchanged
+- Consumers: runtime scenes, capture tool and renderer probes
+
+## Dependencies
+
+- Requires: M01 `StreamingFocus` and merged M02 closeout on master `4f566b1`
+- Blocks: environment/entity/ground facade contracts and planner extraction
+- External state: none; contract verification uses a test double
+
+## Verification
+
+- Commands: dedicated facade verifier, streaming-focus regression, renderer
+  baseline manifest/dry-run, coordinate boundary and repository gates
+- Fixtures: typed focus, source Node3D and read-only metrics test double
+- Fidelity evidence: no renderer configuration, planner, queue, placement,
+  visibility, material, animation or cache behavior changes
+- Performance budget: one source position sample per process frame; target
+  recomputation remains throttled inside the existing streamer
+
+## Documentation deliverables
+
+- Inline public API docs for facade properties and methods
+- Updated world-renderer module specification
+- Updated data-flow, sequence and dependency diagrams
+- Updated source map/status and renderer notes
+
+## Simplicity and naming
+
+- Important names: `WorldRenderFacade`, `renderer_metrics_snapshot`
+- Simplest approach: one small Node adapter delegating to the existing streamer
+- Rejected complexity: service container, generic command bus, streamer rewrite
+  or duplicate queue/cache state
+- Unavoidable complexity: scene-relative source and implementation paths are
+  resolved on the main thread with explicit diagnostics
+- Measured optimization evidence: not applicable; behavior-preserving seam
+
+## Status
+
+- State: ready-for-review
+- Done: introduced the facade, migrated two runtime scenes and three renderer
+  tools, added regression coverage and updated renderer documentation
+- Next: M03 integrator reviews and merges `3d528e3`
+- Blocked by:

+<!-- OPENWC_HANDOFF:READY:M03-RND-FACADE-001:3d528e3 -->

+
+## Handoff
+
+- Commit: `3d528e3`
+- Integration: accepted in master merge `a100ced`
+- Results: `WorldRenderFacade` is the runtime/tool surface for typed focus and
+  detached metrics; the existing streamer remains the sole owner of queues,
+  caches, tasks, nodes and RIDs.
+- Verification: facade `delegation=3 runtime_scenes=2 tools=3`; streaming focus
+  `contract=1 runtime_scenes=2 capture_tools=3`; coordinate boundary
+  `files=105 native_boundary=1 oracle=1 consumers=5 classifier_cases=6`;
+  render manifest `checkpoints=7 coverage=7 caches=7`; seven-checkpoint headless
+  dry-run; coordination/documentation/diff gates passed.
+- Fidelity: no changes to renderer target calculation, budgets, queue order,
+  cache versions, placement, visibility, materials or animation. The dry-run
+  retained all seven checkpoint plans. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts
+  were copied from master only to run the worktree smoke. Proprietary extracted
+  ADT and character GLB data were unavailable, producing the expected dry-run
+  degraded-data diagnostics.
+- Remaining risks: environment, entity visuals and ground query are not yet
+  facade contracts; streamer exported configuration remains transitional scene
+  composition; focus-source sampling adds one small main-thread adapter step per
+  process frame while target refresh remains streamer-throttled.
+- Documentation updated: inline facade API, `docs/modules/world-renderer.md`
+  public API/inputs/outputs/data-flow/sequence/ownership/recovery/status/source
+  map, and `RENDER.md` file map plus implementation note.

+
+## Outcome
+
+Add immutable, versioned world-entity presentation input and stable facade

+
+## Non-goals
+
+- Define authoritative entity/gameplay/network state or allocate/map identities.

+- Reused unchanged: `EntityId`, `GodotWorldPosition`, existing asset-free
+  character presentation model fixture
+- Generated/ignored: `.godot`, native DLL, generated resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Contract version: `EntityPresentationSnapshot.CONTRACT_VERSION = 1`
+- Snapshot: valid session-local `EntityId`, typed Godot world position, visual
+  PackedScene path, finite yaw radians, positive finite uniform scale and visibility
+- Public API: `WorldRenderFacade.present_entity`, `remove_entity`,
+  `entity_presentation_snapshot`
+- Presenter behavior: present is idempotent by entity key; same visual updates
+  transform/visibility, changed visual replaces the owned subtree; remove is explicit
+- Schema/cache/coordinate contracts: no persisted schema or cache change
+
+## Dependencies
+
+- Requires: integrated M03 environment facade master `a85e416`, M01 identity and
+  coordinate contracts
+- Blocks: completion of the first M03 facade checklist item and later entity renderer extraction
+- External state: none; tests use a repository-owned asset-free PackedScene fixture
+
+## Verification
+
+- Commands: cold snapshot contract; presenter lifecycle/ownership regression;
+  facade delegation and runtime wiring; identity/coordinate/internal-access;
+  renderer manifest/shutdown/planner/scheduler/focus and repository gates
+- Fixtures: invalid identity/position/yaw/scale/path, spawn, idempotent update,
+  visual replacement, missing asset, removal, detached diagnostic snapshot and teardown
+- Fidelity evidence: no runtime commands are produced yet, so existing scene output
+  and seven baseline plans remain unchanged
+- Performance budget: constant-time entity lookup; synchronous resource load only
+  on first presentation/visual replacement and explicitly excluded from hot-path acceptance
+
+## Documentation deliverables
+
+- Inline public API docs: snapshot, facade commands and presenter lifecycle
+- Module specification: new world-entity-presentation specification
+- Data-flow diagram: read model through facade into owned visual subtree
+- Sequence/state/dependency diagrams: present/update/replace/remove/failure/teardown
+- Source map/status updates: module registry, world renderer and `RENDER.md`
+
+## Simplicity and naming
+
+- Important names introduced: `EntityPresentationSnapshot`, `WorldEntityPresenter`,

+- Simplest considered solution: one immutable full visual snapshot and one
+  dictionary-owned Node3D presenter below an explicit scene service
+- Rejected complexity/abstractions: ECS, event bus, command hierarchy, factory
+  registry, pooling, async loader framework or duplicate identity registry
+- Unavoidable complexity and justification: renderer must own and deterministically
+  replace/free visual subtrees while authoritative state remains external
+- Measured optimization evidence: no optimization claim; lifecycle is asset-free tested
+
+## Status

+
+## Handoff
+
+- Commit: `1807c3a`
+- Results: facade now exposes idempotent `present_entity`, explicit
+  `remove_entity` and detached diagnostics. Both runtime scenes compose a
+  `WorldEntityPresenter` that owns one replaceable visual subtree per valid
+  session `EntityId`; local player and authoritative state remain separate.
+- Verification: entity `snapshot_cases=8 lifecycle_cases=14 runtime_scenes=2`;
+  facade `delegation=9 entity_contract=6`; identities `5/5/6/5`; character
+  presentation `9/10/3/1`; coordinate boundary `files=119`; internal access

+  (`20000` iterations), planner (`250` iterations), focus, editor parse, dry-run,
+  coordination, documentation and diff gates passed.
+- Fidelity: runtime produces no world-entity commands yet, so all seven baseline
+  plans and existing player/world output remain unchanged. No build-12340
+  display, equipment, animation, effects or visibility parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT scripts supported
+  editor/dry-run only. Missing proprietary ADT/DBC/character corpus produced the
+  expected degraded diagnostics.
+- Remaining risks: PackedScene create/replace loads synchronously and is not an

+
+## Non-goals
+
+- Change Light/Area/Skybox DBC selection, interpolation, fog, sun or shader rules.
+- Add weather, indoor lighting, new clock semantics or build-12340 parity claims.
+- Extract the sky service or move its Environment/Node/RID ownership.

+## Contracts and data
+
+- Public API: immutable `WorldEnvironmentSnapshot` and
+  `WorldRenderFacade.apply_environment_snapshot`
+- Snapshot input: finite time-of-day hours normalized into one 24-hour day
+- Adapter: explicit `world_environment_controller_path`; facade/controller retain

+- Schema/cache/coordinate contracts and runtime defaults: unchanged
+- Consumer: deterministic renderer checkpoint capture; future world-state adapter
+
+## Dependencies
+
+- Requires: integrated M03 facade/ground-query master `cb103e1`
+- Blocks: completion of the facade environment checklist slice and later sky extraction
+- External state: none for contract tests; visual comparison still needs proprietary corpus
+
+## Verification
+
+- Commands: dedicated cold snapshot contract, facade delegation/wiring regression,

+- Fixtures: normalization, non-finite rejection, missing/wrong controller,

+
+## Documentation deliverables
+
+- Inline public API docs: snapshot, facade adapter and sky-controller application
+- Module specification: update existing world-renderer specification
+- Data-flow diagram: snapshot producer through facade into DBC sky controller

+- Important names introduced: `WorldEnvironmentSnapshot`, `apply_environment_snapshot`
+- Simplest considered solution: one immutable time snapshot over the existing sky implementation
+- Rejected complexity/abstractions: generic weather graph, duplicated lighting DTO,

+
+## Handoff
+
+- Commit: `2ee647a`
+- Results: `WorldEnvironmentSnapshot` normalizes finite time into one day and
+  exposes non-finite failure explicitly. `WorldRenderFacade` delegates the
+  immutable value to the existing sky controller; checkpoint capture no longer
+  locates or mutates that controller directly.
+- Verification: snapshot `contract=5`; facade `delegation=6 ground_contract=2
+  environment_contract=7 runtime_scenes=2 tools=3`; internal access `43/7/9/1`;
+  terrain, coordinate (`files=116 consumers=5`), manifest (`7/7`), shutdown,
+  scheduler (`20000` iterations), planner (`250` iterations), focus, editor parse,
+  dry-run capture, coordination, documentation and diff gates passed.
+- Fidelity: applying a snapshot retains the previous three fixed-clock assignments
+  and leaves DBC profile/area/skybox lookup, interpolation, fog, sun, shader,
+  cache and streaming rules unchanged. Dry-run retained all seven plans and
+  reported dusk as `time=19.00`. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts
+  were copied from master for parse/dry-run only. Missing proprietary ADT/DBC/
+  character data produced expected degraded diagnostics.
+- Remaining risks: the snapshot currently covers exact world time only; weather,
+  indoor state and asset-backed paired zone-transition evidence remain open.
+- Documentation updated: inline value/facade/controller API plus world-renderer
+  API/input-output/data-flow/sequence/ownership/failure/capability/source-map and
+  `RENDER.md` implementation notes.
+- Integration: accepted in master merge `c69abd6`; post-merge snapshot, facade,

+
+<!-- OPENWC_CLAIM:M03-RND-FACADE-GROUND-QUERY-001:sindo-main-codex:2026-07-18 -->

+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-facade-ground-query`
+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Expose typed ground-height sampling and a detached readiness diagnostic through
+`WorldRenderFacade`, using already loaded render terrain meshes, and migrate the
+terrain-height probe away from direct streamer state/queue access.
+
+## Non-goals
+
+- Replace the M02 gameplay-owned `TerrainQuery`/`AdtTerrainQuery` composition.
+- Make rendered mesh sampling authoritative for movement, collision or server state.
+- Add slopes, holes, liquid, WMO/M2 collision or async query callbacks.
+- Change terrain meshes, streaming policy, queue order, cache formats or visuals.
+- Complete environment/entity-visual facade contracts or mark M03 complete.
+
+## Paths
+
+- Exclusive: this claim
+- Shared/hotspots: `src/render/world_render_facade.gd`,
+  `src/scenes/streaming/streaming_world_loader.gd`,
+  `src/tools/probe_render_terrain_height.gd`,
+  `src/tools/verify_world_render_facade.gd`,
+  `src/tools/verify_renderer_internal_access.gd`, `docs/modules/world-renderer.md`,
+  `docs/modules/terrain-query.md`, `RENDER.md`, `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated ADT resource scripts,
+  extracted renderer corpus and probe reports
+
+## Contracts and data
+
+- Input: immutable `GodotWorldPosition` in Godot world units
+- Output: renderer-owned immutable `RenderedGroundSample` plus optional detached diagnostic Dictionary
+- Sampling source: loaded quality or tile-LOD Mesh and its live tile transform
+- M02 ADT query cache, renderer cache versions and coordinate contracts: unchanged
+
+## Dependencies
+
+- Requires: M02 terrain query contract and integrated M03 facade/access gate `53d84cc`
+- Blocks: removal of renderer diagnostic internal-access exception and later terrain service extraction
+- External state: asset-backed probe is optional; contract tests use a facade double
+
+## Verification
+
+- Commands: facade query/snapshot isolation contract, internal-access gate,
+  terrain-query regression, focus/coordinate/manifest/shutdown regressions and repository gates
+- Fixtures: available/unavailable sample, detached diagnostic, probe source migration
+- Fidelity evidence: mesh ray/nearest fallback algorithm moves unchanged from the probe
+- Performance budget: on-demand diagnostic query only; no per-frame query added
+
+## Documentation deliverables
+
+- Inline facade/streamer API docs
+- World-renderer API/data-flow/sequence/ownership/recovery/source-map updates
+- Terrain-query backend status/ownership clarification and renderer implementation note
+
+## Simplicity and naming
+
+- Important names: `sample_ground_height`, `renderer_ground_query_snapshot`
+- Simplest approach: one typed facade query over one existing diagnostic read model
+- Rejected complexity: duplicate ADT cache, physics service, callback bus, query node,
+  generic spatial interface or new dependency
+- Unavoidable complexity: triangle-mesh ray query retains the existing bounded
+  nearby fallback for seam/edge diagnostic behavior
+
+## Status
+
+- State: ready-for-review
+- Done: added renderer-owned typed sample, facade query/snapshot, migrated terrain
+  probe, expanded internal-access/coordinate gates and updated module docs
+- Next: M03 integrator reviews and merges `b697a89` plus cold-start fix `9408d88`
+- Blocked by:
+
+<!-- OPENWC_HANDOFF:READY:M03-RND-FACADE-GROUND-QUERY-001:9408d88 -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-FACADE-GROUND-QUERY-001:d6e5b53 -->
+
+## Handoff
+
+- Commits: implementation `b697a89`; cold-start fix `9408d88`
+- Results: `WorldRenderFacade` delegates loaded-mesh ground sampling and returns
+  renderer-owned `RenderedGroundSample`; detached diagnostic snapshots preserve
+  the probe report while hiding queue/tile/Mesh/Node references. Gameplay remains
+  on the independent M02 `TerrainQuery` composition.
+- Verification: facade `delegation=5 ground_contract=2 runtime_scenes=2 tools=3`;
+  cold rendered-ground value `contract=3` from an empty Godot class cache;
+  internal access `private_symbols=43 gameplay=7 editor_sources=9 renderer_tools=1`;
+  terrain query contracts passed; coordinate boundary `files=113 consumers=5`;
+  renderer manifest `7/7`; shutdown ownership, scheduler/planner, coordination,
+  documentation and diff gates passed.
+- Fidelity: the probe's 5000-unit ray height, 3x3 tile search, highest-hit choice,
+  readiness fields and `2/5/10/20/40` nearby fallback moved unchanged. No terrain
+  geometry, streaming, cache, material, placement or visual rule changed. No
+  build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts
+  were copied from master only for editor/streamer parse and then removed.
+  Proprietary extracted world data was unavailable, producing expected degraded diagnostics.
+- Remaining risks: triangle-mesh generation is on-demand/main-thread and diagnostic;
+  it is unsuitable for per-physics-frame gameplay; exact asset-backed probe output
+  still depends on local corpus readiness; environment/entity facade contracts remain.
+- Documentation: inline facade/loader/value API; world-renderer API/data-flow/
+  sequence/ownership/recovery/capability/source map; terrain-query authority
+  clarification and renderer implementation notes updated.
+- Integration: implementation accepted in master merge `80cb084`; cold-start fix
+  accepted in merge `d6e5b53`. Post-merge cold/facade/access/terrain/coordinate/
+  manifest/shutdown/scheduler/planner/focus and repository gates passed.

+- Branch: `work/sindo-main-codex/m03-streamer-internal-access-gate`
+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Add an automated repository boundary gate proving gameplay code and Godot
+`EditorPlugin` implementations do not access `StreamingWorldLoader` private
+queue, task, cache or tile-state fields.
+
+## Non-goals
+
+- Change renderer behavior, queues, jobs, cache formats or facade contracts.
+- Ban scene composition references to the loader script or facade adapter path.
+- Migrate renderer-only diagnostic probes that inspect internal readiness/terrain;
+  those require the later metrics/ground-query facade contract.
+- Mark M03 complete.
+
+## Paths
+
+- Exclusive: `src/tools/verify_renderer_internal_access.gd`, this claim
+- Shared/hotspots: `docs/modules/world-renderer.md`, `RENDER.md`,
+  `targets/03-renderer-facade.md`
+- Read-only scan scope: `src/gameplay/**/*.gd`, `src/editor/**/*.gd`, Godot
+  `EditorPlugin` package scripts under `src/**/*.gd` and `addons/**/*.gd`, and
+  the streamer field declarations
+
+## Contracts and data
+
+- Input: repository GDScript source and actual private streamer declarations
+- Output: deterministic pass/fail diagnostics with consumer path and symbol
+- Runtime, scene, cache, coordinate and asset contracts: unchanged
+
+## Dependencies
+
+- Requires: integrated facade and scheduler master `a023d76`
+- Blocks: safe service extraction and M03 dependency regression acceptance
+- External state: none
+
+## Verification
+
+- Commands: dedicated internal-access gate, facade regression, coordination,
+  documentation and diff gates
+- Fixtures: gameplay source discovery, EditorPlugin discovery and synthetic
+  forbidden symbol detection
+- Fidelity evidence: source-only enforcement; no runtime or visual code changes
+- Performance budget: one bounded repository source scan in a headless test process
+
+## Documentation deliverables
+
+- World-renderer boundary/verification/known-gap/source-map updates
+- Renderer implementation note documenting diagnostic-tool exception
+- No new module spec because this package adds a verifier to the existing renderer module
+
+## Simplicity and naming
+
+- Important name: `verify_renderer_internal_access.gd`
+- Simplest approach: derive forbidden fields from the current streamer instead
+  of maintaining a second hand-written queue list
+- Rejected complexity: language plugin, custom linter framework or runtime proxy
+- Unavoidable complexity: recursive source discovery expands each actual
+  `EditorPlugin` root to its package scripts while excluding reference mirrors
+
+## Status
+
+- State: ready-for-review
+- Done: derived 43 private renderer symbols, scanned seven gameplay and nine
+  EditorPlugin-package sources, added synthetic positive/negative fixtures and docs
+- Next: M03 integrator reviews and merges `b58bf2c`
+- Blocked by:
+
+<!-- OPENWC_HANDOFF:READY:M03-RND-INTERNAL-ACCESS-GATE-001:b58bf2c -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-INTERNAL-ACCESS-GATE-001:7e35de7 -->
+
+## Handoff
+
+- Commit: `b58bf2c`
+- Results: repository gate derives private queue/task/cache/state declarations
+  from the streamer and rejects external member/reflection access in gameplay and
+  EditorPlugin package sources. Current scope passes with `43/7/9` inventory counts.
+- Verification: internal access, facade and budget scheduler headless contracts;
+  Godot editor scan with local ignored dependencies; coordination, documentation
+  and diff gates passed.
+- Fidelity: source-only enforcement changes no runtime configuration, queue order,
+  cache version, placement, material, animation or visibility behavior. No
+  build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and two generated ADT resource scripts
+  were copied from master only for facade/editor smoke and then removed. Proprietary
+  extracted world data was unavailable, producing expected degraded-data diagnostics.
+- Remaining risks: renderer diagnostic terrain probe remains an explicit exception;
+  whitespace-obfuscated dynamic reflection is outside the lightweight source gate;
+  future non-EditorPlugin authoring code is already prohibited by repository policy.
+- Documentation: world-renderer boundary/verification/capability/known-gap/source
+  map and `RENDER.md` implementation note updated; no new module was introduced.
+- Integration: accepted in master merge `7e35de7`; post-merge access gate
+  `private_symbols=43 gameplay=7 editor_sources=9`, facade/scheduler/planner and
+  repository gates passed.

+# M03-RND-M2-RUNTIME-REBUILD-CLASSIFIER-001 — M2 runtime rebuild classifier
+
+<!-- OPENWC_CLAIM:M03-RND-M2-RUNTIME-REBUILD-CLASSIFIER-001:sindo-main-codex:2026-07-20 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-m2-runtime-rebuild-classifier`
+- Lease expires UTC: 2026-07-20
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Extract the memoized decision that stale cached M2 meshes require an in-memory
+runtime rebuild because raw batches contain billboard vertices or referenced UV
+rotation transforms.
+
+## Non-goals
+
+- Load raw M2 files or cache Resources.
+- Build, replace or mutate Meshes, materials, Nodes or RIDs.
+- Change `M2_MATERIAL_REFRESH_VERSION` or cache formats.
+- Interpret animation, particles, ribbons or general M2 shader fidelity.
+- Change path normalization, ResourceLoader transitions or finalize budgets.
+
+## Paths
+
+- Exclusive: `src/render/m2/m2_runtime_mesh_rebuild_classifier.gd`,
+  `src/tools/verify_m2_runtime_mesh_rebuild_classifier.gd`,
+  `docs/modules/m2-runtime-mesh-rebuild-classifier.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,
+  `docs/modules/world-renderer.md`, `docs/modules/README.md`, `RENDER.md`,
+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated ADT/M2 resources, caches
+  and proprietary renderer corpus
+
+## Contracts and data
+
+- Billboard metadata requires rebuild when `has_billboard` is true or
+  `billboard_vertex_count` is positive in any Dictionary batch.
+- UV rotation requires non-empty transforms and combos plus a referenced
+  non-identity `Vector4` rotation or absolute rotation speed above `0.000001`.
+- Only up to four texture stages per batch are inspected; invalid variants and
+  out-of-range combo/transform indices are skipped.
+- The first decision for a normalized path is memoized until clear, matching the
+  existing loader cache lifetime.
+
+## Dependencies
+
+- Requires: current accepted master `90b1dac`
+- Blocks: further M2 mesh request/cache/finalization extraction
+- External state: none; verification uses synthetic raw M2 Dictionaries
+
+## Verification
+
+- Commands: dedicated billboard/UV/index/stage/cache/clear/source/timing verifier;
+  M2 builder/grouper/transform/registry, materials, shutdown, facade,
+  internal-access, manifest, documentation and coordination gates
+- Fixtures: synthetic batches, transform combos and rotation dictionaries
+- Fidelity evidence: exact existing predicate thresholds, stage cap and cache lifetime preserved
+- Performance budget: 100 classifications over 256 paths under 1 second
+
+## Documentation deliverables
+
+- Inline public API docs
+- Module specification with inputs/outputs, ownership and source map
+- Data-flow, lifecycle/state, sequence and dependency diagrams
+- World-renderer, module registry and RENDER status updates
+
+## Simplicity and naming
+
+- Important names introduced: `M2RuntimeMeshRebuildClassifier`
+- Simplest considered solution: one RefCounted with one memoized query and clear
+- Rejected complexity/abstractions: generic predicate cache, strategy interface,
+  ResourceLoader wrapper, signals or typed rewrite of raw parser Dictionaries
+- Unavoidable complexity and justification: four-stage combo indirection is the
+  existing build-12340 M2 material boundary
+- Measured optimization evidence: bounded synthetic classification loop
+
+## Status
+
+- State: accepted
+- Done: classifier/cache implemented; loader query and both clear sites migrated;
+  synthetic predicate/cache verifier and required documentation added
+- Next: continue M2 mesh request/cache/finalization extraction
+- Blocked by:
+
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-M2-RUNTIME-REBUILD-CLASSIFIER-001:38f831e -->
+
+## Handoff
+
+- Commit: `19ca8f4`
+- Results: classifier PASS (`cases=12`, `iterations=100`,
+  `elapsed_ms=64.585`; initial `35.461ms`); billboard flag/count, invalid
+  variants/indices, UV rotation/speed/epsilon, four-stage cap, memoization,
+  detached diagnostics and clear contracts PASS; 33 M2/WMO/liquid/terrain/
+  facade/scheduler/streaming/coordinate/material/shutdown regressions PASS;
+  internal-access decreased to `35`; documentation and coordination gates PASS;
+  checkpoint dry-run PASS `7/7`.
+- Remaining risks: raw parser data remains Dictionary-based; the first decision
+  for a path remains authoritative until clear; classification covers the current
+  four-stage material implementation only; private asset descriptor-pressure,
+  traversal, p95/p99 and paired original-client evidence remain absent.
+- Documentation updated: inline public API; new
+  `docs/modules/m2-runtime-mesh-rebuild-classifier.md`; module registry, world
+  renderer and `RENDER.md`; data-flow/state/sequence/dependency diagrams,
+  ownership, failure/recovery, thresholds, cache lifetime and source map included.
+- Integration: merged as `38f831e`; post-merge classifier (`cases=12`,
+  `iterations=100`, `elapsed_ms=45.439`), materials, shutdown, M2 batch planner,
+  facade, internal-access (`private_symbols=35`), `7/7` manifest, documentation
+  and coordination gates passed.

+
+## Outcome
+
+Extract cross-tile positive `MDDF.uniqueId` reservation ownership from the

+
+## Non-goals
+
+- Move tile state, candidate requeue, group/build tasks or result queues.
+- Move MultiMesh/Node/Mesh/material creation, animation or resource loading.
+- Change unique-key format, first-owner semantics or unkeyed placement behavior.
+- Change placement transforms, detail radius, cache versions or quality profiles.
+- Add dependencies or mark the broad M2 service complete.

+- Generated/ignored: `.godot`, native DLL, generated ADT resources, caches and

+
+## Contracts and data
+
+- Input: tile key and raw ADT M2 placement dictionaries
+- Reserve output: fresh filtered placements, owned unique keys and skipped keys
+- Release input/output: tile key plus claimed keys; only current owner releases
+- Positive IDs map to `uid:<decimal>`; zero/negative/missing IDs remain untracked
+- Registry is session-memory only and clears on renderer world reset
+- Queue/cache/schema/coordinate versions: unchanged
+
+## Dependencies
+
+- Requires: current master `57ae1b8`
+- Blocks: broader M2 service extraction and dependency/performance acceptance
+- External state: none; tests use synthetic placement dictionaries
+
+## Verification
+
+- Commands: dedicated unkeyed/duplicate/cross-tile/release/clear/detached-
+  diagnostic and bounded timing verifier; loader source boundary; M2 unique-id
+  smoke plus facade/terrain/internal-access/manifest/shutdown/scheduler gates
+- Fidelity evidence: exact positive-ID key format and first-owner/retry behavior

+
+## Documentation deliverables
+
+- Inline registry API documentation
+- New module spec with inputs/outputs, data-flow, lifecycle, sequence, ownership,
+  failure, recovery, performance and source map
+- World renderer/module registry/`RENDER.md` updates
+
+## Simplicity and naming
+
+- Important name: `M2UniquePlacementRegistry`
+- Simplest solution: one private key-to-owner dictionary and explicit operations
+- Rejected complexity: generic identity registry, signals, callbacks, Resources,
+  locks or ownership graph
+- Unavoidable complexity: raw placement dictionaries remain at ADT adapter boundary
+- Measured optimization evidence: bounded synthetic reserve/release verifier

+  internal inventory remains `42`; editor parse and documentation/coordination/
+  diff gates PASS; checkpoint dry-run planned `7/7`
+- Remaining risks: private Azeroth corpus was absent, so the asset-backed ADT
+  placement probe could not open the map and is not counted as passed evidence;
+  first ownership remains processing-order based; M2 grouping/build/tasks/caches/
+  finalization and asset-backed p95/p99 remain pending

+- Branch: `work/sindo-main-codex/m03-render-budget-scheduler`
+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Extract the streamer's per-frame main-thread operation quotas into a scene-free
+`RenderBudgetScheduler`, preserving existing queue priority and quota values and
+stopping permit issuance after renderer teardown cancellation.
+
+## Non-goals
+
+- Move queue, worker-task, cache, Node, Resource or RID ownership out of the streamer.
+- Change queue ordering, concurrency limits, exported defaults or visual behavior.
+- Add a generic job framework, priority graph, time-based adaptive budgeting or dependency.
+- Change cache formats, renderer profiles or target milestone status.
+
+## Paths
+
+- Exclusive: `src/render/streaming/render_budget_scheduler.gd`,
+  `src/tools/verify_render_budget_scheduler.gd`,
+  `docs/modules/render-budget-scheduler.md`, this claim

+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated cache resources and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Input: immutable per-frame map from documented operation lane IDs to
+  non-negative operation limits
+- Output: boolean permits and remaining/consumed diagnostic snapshots
+- Lifecycle: `begin_frame` resets permits; `cancel` permanently rejects permits
+  for the current scheduler instance
+- Queue contents, ordering, task concurrency and schema/cache versions: unchanged
+- Consumer: `StreamingWorldLoader` main-thread queue/finalize drains
+
+## Dependencies
+
+- Requires: integrated M03 facade and streaming planner on master `650d584`
+- Blocks: renderer performance regression gate and per-service extraction
+- External state: none; tests use synthetic lane limits and no world assets
+
+## Verification
+
+- Commands: dedicated scheduler verifier, facade/planner/focus/coordinate
+  regressions, renderer manifest/dry-run and repository gates
+- Fixtures: shared lane priority, independent lanes, zero/negative limits,
+  frame reset, unknown lane and cancellation
+- Fidelity evidence: operation defaults and loop order are captured before
+  migration; all seven renderer checkpoint plans remain valid
+- Performance budget: permit checks are constant-time dictionary operations and
+  create no Node, Resource, worker task, cache entry or RID
+
+## Documentation deliverables
+
+- Inline API docs for scheduler lifecycle, permits and diagnostics
+- New module specification with input/output table, data-flow, sequence and
+  lifecycle diagrams
+- Updated world-renderer flow/ownership/source map, module registry and renderer notes
+
+## Simplicity and naming
+
+- Important name: `RenderBudgetScheduler`
+- Simplest approach: one small main-thread service with named quota lanes
+- Rejected complexity: generic job graph, callbacks, queue ownership, adaptive
+  timing controller, service container or third-party dependency
+- Unavoidable complexity: chunk removal and creation intentionally share one
+  lane so removal retains priority while consuming the same historical budget
+- Measured optimization evidence: no optimization claim; exact bounded extraction
+
+## Status
+
+- State: ready-for-review
+- Done: extracted all 16 historical operation quotas, migrated ordered drains,
+  added terminal teardown cancellation, asset-free verification and module docs
+- Next: M03 integrator reviews and merges `e52f703`
+- Blocked by:

+<!-- OPENWC_HANDOFF:READY:M03-RND-SCHEDULER-001:e52f703 -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-SCHEDULER-001:7ece2ab -->
+
+## Handoff
+
+- Commit: `e52f703`
+- Results: `RenderBudgetScheduler` owns only per-frame lane counters and terminal
+  cancellation; `StreamingWorldLoader` retains queue order, task/cache/node/RID
+  ownership and operation execution. Chunk removal/create share one historical budget.
+- Verification: scheduler `cases=6 iterations=20000 elapsed_ms=7.495`; planner
+  `cases=5 average_ms=1.879`; facade/focus contracts passed; coordinate boundary
+  `files=111 consumers=6`; renderer manifest `checkpoints=7 coverage=7 caches=7`;
+  shutdown ownership, documentation, coordination and diff gates passed.
+- Fidelity: exported defaults, quality presets, queue order, operation sites,
+  cache versions and visible rendering rules are unchanged. Seven checkpoint
+  plans remain valid. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and two generated ADT resource scripts
+  were copied from master only for the worktree parse/smoke and then removed.
+  Proprietary extracted ADT data was unavailable, producing expected degraded-data diagnostics.
+- Remaining risks: queue storage length and worker concurrency remain streamer-owned;
+  cancellation stops permit issuance but does not interrupt in-flight work; exact
+  p95/p99 impact still requires an asset-backed baseline.
+- Documentation: new scheduler module spec with API, input/output, data-flow,
+  sequence, lifecycle, ownership, cancellation, performance and source-map sections;
+  world renderer, module registry and renderer implementation notes updated.
+- Integration: accepted in master merge `7ece2ab`; post-merge scheduler timing
+  `cases=6 iterations=20000 elapsed_ms=10.216`, all listed regressions and gates passed.

+
+## Contracts and data
+
+- Input: immutable `GodotWorldPosition`, available-tile key set and immutable

+- Tile-key representation remains the streamer's existing `<x>_<y>` internal key
+- Schema/cache/coordinate versions: unchanged
+- Consumers: `StreamingWorldLoader` runtime/editor refresh paths
+
+## Dependencies
+
+- Requires: M01 typed coordinates/focus and integrated facade package `a100ced`

+## Verification
+
+- Commands: dedicated planner verifier, facade/focus/coordinate regressions,

+- Fixtures: center, edge, corner, unavailable-tile, clamped-radius and editor cases
+- Fidelity evidence: expected tile sets are captured from current formulas; full

+- Updated world-renderer data-flow/sequence/ownership/source map
+- Updated module registry and renderer notes

+- Fidelity: center/corner/catalog/clamp/editor fixtures preserve the extracted
+  formulas; seven-checkpoint dry-run retained all plans. No radius, threshold,
+  load priority, cache version, placement, material, animation or visibility
+  rule changed. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts

+## Outcome
+
+Extract the full-quality terrain revisit Mesh cache, its LRU ownership and

+`TerrainQualityMeshCache`, preserving all call sites and observable behavior.
+
+## Non-goals
+
+- Move ADT parsing, tile state, quality-upgrade tasks/results or SceneTree/RID finalization.
+- Change cache capacity defaults, quality profiles, source priority or cache formats.
+- Cache control-splat/splat meshes that the current loader deliberately rejects.
+- Extract chunk LOD, terrain material building, ground query or other asset services.
+- Add dependencies, persistence, background work or mark the terrain service complete.

+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Public service API: `store`, `restore`, `clear`, detached `diagnostic_snapshot`
+- Entry: tile key, retained Mesh reference and source string
+- Admission: non-empty key, non-null Mesh, source other than
+  `control_splat_cache`, `splat_cache` or `splat`
+- LRU: successful restore touches newest; store touches then trims oldest to
+  `max(0, capacity)`; invalid restored records are removed
+- Persistence/cache format: none; session-memory ownership only
+
+## Dependencies
+
+- Requires: integrated facade contracts master `61bad09`
+- Blocks: later terrain service extraction and cache/finalization acceptance audit
+- External state: none; tests use synthetic ArrayMesh references
+
+## Verification
+
+- Commands: dedicated cache contract/LRU/ownership regression; streamer source
+  boundary; shutdown/facade/internal-access/manifest/planner/scheduler and repository gates
+- Fixtures: admission/rejection, replacement, LRU touch/eviction, zero/negative
+  capacity, invalid record cleanup, clear and detached diagnostics
+- Fidelity evidence: same sources/capacity/call sites; all seven baseline plans unchanged
+- Performance budget: dictionary lookup plus bounded single-entry LRU operations;
+  no Node, task, file, cache serialization or RID creation
+
+## Documentation deliverables
+
+- Inline public API docs: store/restore/clear/diagnostics and ownership
+- Module specification: new terrain quality mesh cache specification
+- Data-flow diagram: upgrade result through cache to revisit state
+- Sequence/state/dependency diagrams: store/restore/evict/reset and failure paths
+- Source map/status updates: module registry, world renderer and `RENDER.md`
+
+## Simplicity and naming
+
+- Important names introduced: `TerrainQualityMeshCache`
+- Simplest considered solution: one RefCounted with dictionary plus ordered tile-key array
+- Rejected complexity/abstractions: generic cache framework, weak references,
+  callbacks, Resource cache integration, background eviction or persistence
+- Unavoidable complexity and justification: Mesh references must survive unloaded
+  tile state while LRU keeps revisit memory bounded
+- Measured optimization evidence: exact ownership extraction, no optimization claim
+
+## Status
+

+
+## Handoff
+
+- Commit: `97480e0`
+- Results: `TerrainQualityMeshCache` now owns retained full-quality Mesh
+  references, source admission and oldest-to-newest LRU. The loader retains only
+  restore-to-state, store-after-upgrade and clear lifecycle adapters.
+- Verification: cache `contract_cases=15 loader_calls=3`; facade/entity/ground/
+  terrain regressions; internal access `private_symbols=42 gameplay=7
+  editor_sources=9 renderer_tools=1`; manifest `7/7`; shutdown; scheduler
+  `20000` iterations; planner `250` iterations; focus; editor parse; dry-run;
+  coordination, documentation and diff gates passed.
+- Fidelity: `baked_full` revisit retention, three excluded splat sources, LRU
+  touch/trim, profile capacities and all call sites remain unchanged. All seven
+  checkpoint plans remain valid. No visible or build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT scripts supported
+  parse/dry-run only; missing proprietary ADT/DBC/character data produced expected diagnostics.
+- Remaining risks: entry count does not measure Mesh bytes; ordered-array touch
+  remains linear; asset-backed revisit flash, memory and p95/p99 evidence remain pending;
+  terrain build/tasks/state/finalization are still monolithic.
+- Documentation updated: new terrain cache API/input-output/data-flow/lifecycle/
+  sequence/ownership/failure/configuration/migration/diagnostic/source-map spec;
+  world renderer, registry and `RENDER.md` updated.
+- Integration: accepted in master merge `630a0c1`; post-merge cache, facade,

+
+## Outcome
+
+Extract chunk-geometry create/remove desired-operation calculation from the
+streamer into a scene-free `TerrainChunkGeometryQueuePlanner`.
+
+## Non-goals
+
+- Move queue storage/drains, render budgets, tile-LOD queues or async tasks.
+- Move chunk Mesh/Node/RID creation/removal or terrain state ownership.
+- Change removal-first execution, nearest-first create order or LOD selection.
+- Change coordinate conversions, radii, cache formats or quality profiles.
+- Add dependencies or mark the broad terrain service checklist complete.
+
+## Paths
+
+- Exclusive: `src/render/terrain/terrain_chunk_geometry_queue_planner.gd`,

+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated ADT resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Input: loader-owned tile-state read model plus immutable `GodotWorldPosition`
+- Output: fresh create/remove request arrays; planner retains no queue state
+- Removal: current chunks absent from desired state, or all current chunks while
+  tile LOD is desired
+- Creation: missing or LOD-mismatched chunks, sorted by origin XZ distance
+- Queue/cache/schema/coordinate versions: unchanged
+
+## Dependencies
+
+- Requires: integrated terrain LOD planner master `b568768`
+- Blocks: broader terrain service extraction and dependency/performance acceptance
+- External state: none; tests use synthetic tile/chunk dictionaries
+
+## Verification
+
+- Commands: dedicated removal/create/mismatch/tile-fallback/sparse/order and
+  bounded timing verifier; loader source boundary; facade/cache/LOD/internal-access/
+  manifest/shutdown/scheduler/streaming planner and repository gates
+- Fidelity evidence: extracted branch/order/distance rules and loader drain order
+- Performance budget: bounded linear planning plus existing create sort; no engine
+  resource, task, cache or persistent allocation framework
+
+## Documentation deliverables
+
+- Inline planner API documentation
+- New module spec with inputs/outputs, data-flow, lifecycle, sequence, ownership,
+  failure, performance and source map
+- World renderer/module registry/`RENDER.md` updates
+
+## Simplicity and naming
+
+- Important name: `TerrainChunkGeometryQueuePlanner`
+- Simplest solution: one stateless planner returning two fresh arrays
+- Rejected complexity: generic operation graph, queue class, callback strategy,
+  spatial index or ownership transfer
+- Unavoidable complexity: raw dictionaries remain at the loader/ADT adapter boundary
+- Measured optimization evidence: bounded synthetic multi-tile verifier

+# Renderer Camera Pose Sweep
+
+This offline M00 diagnostic recovers reproducible checkpoint framing when an original-client screenshot has no recorded camera yaw or pitch. It ranks a bounded grid; it does not change renderer or player-camera defaults and does not prove the exact build 12340 camera pose without human approval.
+
+## Camera contract
+
+`capture_render_checkpoints.gd` accepts additive `--camera-yaw-offset` and `--camera-pitch-offset` values in degrees. Yaw rotates the no-roll checkpoint basis around Godot world `Vector3.UP`; pitch then rotates around the camera-local right axis. Zero offsets preserve the manifest target exactly. `--single-pass` captures only `cold_process` and is intended for pose calibration, not performance baselines.
+
+## Workflow
+
+```powershell
+.\tools\sweep_render_checkpoint_camera_pose.ps1 `
+  -ReferenceDirectory 'D:\private-fixtures\wow-3.3.5a-checkpoints' `
+  -Checkpoint elwynn_adt_boundary `
+  -YawOffsets -15,-10,-5,0,5,10,15 `
+  -PitchOffsets -10,-5,0,5,10 `
+  -CameraFovValues 38,50,62 `
+  -ViewportWidth 1280 -ViewportHeight 960 `
+  -WaitSeconds 8
+```
+
+Each candidate receives its own output directory and comparison report. `-CameraFovValues` adds FOV as another bounded grid dimension; omit it to retain the scalar `-CameraFov` workflow and legacy candidate paths. The viewport must exactly match the reference image dimensions; the runner fails on `size_mismatch` instead of inventing a score. The default 8-second wait matches the M00 manifest and is a readiness precondition: lowering it requires evidence that the checkpoint's WMO/M2 content has already appeared. `ranking.json` sorts candidates by mean perceptual error and then changed-pixel ratio. Use `-PlanOnly` to validate the Cartesian grid and output paths without rendering. Run a coarse grid first, then a finer grid around the best candidate.
+
+```mermaid
+flowchart LR
+    Y[Yaw offsets in degrees] --> G[Bounded Cartesian grid]
+    P[Pitch offsets in degrees] --> G
+    G --> C[Single-pass checkpoint captures]
+    R[Original-client reference] --> D[Perceptual comparator]
+    C --> D
+    D --> J[ranking.json]
+    J --> H[Human framing approval]
+```
+
+## Interpretation and recovery
+
+The smallest error is a candidate, not automatic fidelity approval. Geometry, materials, lighting and FOV can move the perceptual optimum away from the true original-client pose. Inspect the best images manually and retain the original reference outside Git. A missing matching reference or candidate is a hard error; correct the checkpoint filter or filenames and rerun. Generated PNG and JSON outputs are disposable local evidence.
+
+## Verification
+
+The headless capture dry-run must report requested yaw and pitch offsets. Comparator `--self-test` covers paired metrics. Sweep `-PlanOnly` covers deterministic grid expansion and output naming without requiring a display. A real ranked sweep requires a display and a private build 12340 reference image.
+
+## Goldshire Inn evidence — 2026-07-12
+
+The private `2560x1440` build 12340 `goldshire_inn_large_wmo` reference was evaluated at FOV 62 degrees. A coarse 5x5 grid over yaw/pitch `[-20, -10, 0, 10, 20]` reduced mean error from `0.099632` at `(0, 0)` to `0.077575` at `(-10, -20)`. Extending pitch produced `0.070901` at `(0, -40)` and `0.063574` at `(0, -60)` with changed-pixel ratio `0.549556`.
+
+These values are invalid camera-pose evidence because the sweep used a 2-second wait. A subsequent readiness audit showed 9 WMO instances and no inn after 2 seconds, 113 instances with the inn visible after 8 seconds, and 328 instances after 15 seconds. The apparent monotonic improvement rewarded grass while the landmark was still absent; it does not demonstrate a spatial/placement defect. The manifest pose remains unchanged pending a ready-scene rerun.
+
+The ready-scene 3x3 rerun at FOV 62 degrees ranked `(yaw=10, pitch=-10)` first with mean error `0.087952` and changed-pixel ratio `0.665527`, compared with `0.101402`/`0.702489` at zero offsets. Human inspection confirms that the inn is present and the direction is plausible. Pitch remains on the tested boundary and the building scale differs from the reference, so these offsets are coarse evidence only; a joint pitch/FOV refinement is required before changing manifest camera values.
+
+## Goldshire joint pitch/FOV refinement — 2026-07-12
+
+A WMO-ready joint grid fixed yaw at 10 degrees and evaluated pitch `[-25, -20, -15, -10, -5]` across FOV `[38, 50, 62]`. Full-frame error ranked FOV 62/pitch -25 first at `0.078843` with changed-pixel ratio `0.667721`. Human inspection rejects it as a manifest calibration: the view is dominated by grass and crops the inn. FOV 38/pitch -10 is closer to the reference building scale but ranks only `0.084220`, and horizontal landmark alignment remains different.
+
+The grid therefore has no approved joint optimum. Full-frame color error continues to trade landmark framing against large terrain regions. The manifest remains unchanged. The next registration method must score an approved inn/road/tree landmark region or explicit landmark coordinates rather than the entire image.
+
+## Common landmark region — 2026-07-12
+
+The comparator accepts an optional common screen rectangle through `--region x,y,width,height`; the sweep runner exposes it as `-ComparisonRegion x,y,width,height`. Coordinates are integer pixels in the shared reference/candidate image space. Both images must have identical dimensions and the rectangle must be fully inside them. Omitting the option preserves full-frame behavior.
+
+The existing 15 WMO-ready Goldshire candidates were rescored inside `[300,100,1400,650]`, covering the reference facade/chimney and nearby trees. ROI error ranked FOV 38/yaw 10/pitch -15 first at `0.081777` with changed-pixel ratio `0.697185`. This is an interior pitch candidate and improves on the full-frame grass preference, but human inspection still rejects manifest calibration: the facade is too large, its upper part is cropped, and the rectangle retains substantial road/terrain pixels. A common rectangle is useful diagnostic weighting, not semantic landmark registration. Explicit approved landmark coordinates or a mask remain necessary.
+
+During this run the sweep orchestration was hardened in two ways: expected comparator exit code `1` is now collected through an explicit child process, and viewport dimensions are explicit. A reference/candidate `size_mismatch` now fails before ranking instead of producing an empty metric.

+# M00 Final Paired Evidence — 2026-07-13
+
+## Scope and result
+
+The final local M00 audit used Godot 4.6.1, the existing cache state, the manifest-standard 8-second readiness wait, and `2560x1440` visual candidates. Seven private WoW 3.3.5a build 12340 references produced fourteen cold/warm comparisons with no missing pair. Private images and generated reports remain outside Git.
+
+Every pair exceeded the strict regression tolerance. Comparator exit code `1` means a valid report with measured visual gaps; only codes outside `0/1` are infrastructure failures. This evidence establishes coverage and current differences, not renderer parity.
+
+```powershell
+.\tools\run_render_baseline.ps1 `
+  -Output user://render_baseline_m00_complete_2026-07-13 `

+  -VisualComparisonWidth 2560 `
+  -VisualComparisonHeight 1440
+```
+
+The initial shell timeout detached the canonical capture process after it started. The process completed all fourteen canonical captures and wrote `report.json`; the documented visual-capture and comparator stages were then invoked separately with the same arguments. The final output directory contains both complete reports.

+Cold and warm values are close for all seven references. The measured gaps are therefore not explained by first-visit cache readiness. Goldshire timing evidence separately demonstrated that the 8-second wait is necessary for WMO publication.

+
+An ADT scan found no `GryphonRoost01` placement in Goldshire. The M00 checkpoint deliberately injects the model there as a synthetic probe. The original-client observation therefore uses two real Lakeshire placements. The three-second pose change establishes `Observed` native animation behavior, but the full-frame comparison cannot establish spatial or animation-phase parity.
+
+## Fidelity interpretation
+
+M00 now has private build 12340 evidence for every required coverage category: terrain, ADT boundary, dense M2, large WMO, liquid, animated M2 and sky transition. The sky reference is approximately paired by map position/time and manually approved composition. Animated-M2 evidence is asset-paired but placement-unpaired because the OpenWC probe is synthetic.
+
+The reports demonstrate current differences and do not claim `1:1`. Camera calibration experiments also show that unknown manual yaw/pitch/FOV cannot be recovered reliably from full-frame color error alone. Region scoring reduces terrain bias but still requires semantic landmark approval.
+
+## Operational risks
+
+A follow-up shutdown ownership fix removed the GUI renderer leaks found by the final visual capture. Before the fix, the focused animated-M2 checkpoint retained 6 mesh, 6 material, 4 shader, 6 texture, 6 instance and associated RenderingDevice RIDs, for 30 resources in use. After the fix, both the focused 8-second capture and a seven-checkpoint single-pass capture completed without Node, resource or RID leak diagnostics.
+
+Godot can still emit a timing-dependent ObjectDB warning for one or more anonymous `RefCounted` objects whose reported reference count is already zero. The warning has no retained Node, renderer resource or RID ownership in the verified captures. It remains recorded as an engine-teardown diagnostic rather than being hidden, but it is distinct from the resolved GUI renderer leak.
+
+## Integrator decision checklist
+
+- Seven required reference checkpoints: cold/warm report complete, `compared=14`, `missing=0`.
+- Animated M2: build-12340 native motion observed in two phases; synthetic/real placement mismatch explicitly classified.
+- Sky transition: build-12340 19:00 evidence present with approximate paired camera and human-approved composition.
+- Renderer visual differences: registered as gaps, not parity claims.
+- GUI renderer RID/resource diagnostics: resolved by explicit shutdown ownership and covered by a headless regression verifier; the residual zero-reference `RefCounted` engine-teardown warning remains tracked separately.
+- Target status, target Evidence and `OPENWC_TARGET_DONE` marker: integrator-only actions.

 Первый paired run после калибровки создал десять сравнений (пять reference × cold/warm), без missing pairs. Все пары ожидаемо превысили строгий tolerance: mean perceptual error `0.0707..0.1746`, changed-pixel ratio `0.5504..0.8187`. Human inspection показал, что это пока не чистая material/lighting ошибка: при тех же WoW-derived координатах OpenWC terrain-overview camera находится под terrain/placements, WMO camera — внутри таверны, liquid camera — внутри скал; ADT и dense-M2 композиции также существенно смещены. До исправления coordinate/placement mismatch эти значения являются gap evidence, а не основанием расширять tolerance.
 
 Capture tool строит camera basis явно из target и world-up. Это исключает неоднозначный roll `look_at` при автоматической съёмке. `ViewportTexture.get_image()` сохраняется без дополнительного vertical flip для Godot 4.6.1.

+## Coordinate calibration

+    W --> G[Manifest Godot camera XYZ]
+    G --> R[Godot to WoW round-trip]
+    R --> E[Maximum numeric error]
+```
+
+На пяти точках maximum mapping/round-trip error равен `0.000015`. Это исключает текущую формулу `gx = center - wy`, `gy = wz`, `gz = center - wx` как источник крупного paired mismatch. Результат не доказывает renderer parity: следующая диагностика должна отдельно проверить terrain height, placement transforms и фактическое camera direction/FOV. Production `CoordinateMapper` остаётся задачей M01; M00 probe не создаёт второй публичный coordinate contract.
+
+## Terrain height diagnostic
+
+Rendered terrain проверяется без нового runtime API: offline probe использует уже загруженный tile mesh, строит `TriangleMesh` и выполняет вертикальный ray в tile-local space.
+
+```powershell
+godot --headless --path . --script res://src/tools/probe_render_terrain_height.gd -- --wait 2
+```
+
+```mermaid
+flowchart LR
+    C[Calibrated camera XZ] --> S[Streaming tile state]
+    S --> M[Active terrain mesh]
+    M --> T[Tile-local TriangleMesh ray]
+    T --> H[Terrain height and camera clearance]
+```
+
+Измеренный clearance: terrain overview `89.044`, ADT boundary `44.788`, dense M2 `90.178`, large WMO `12.034`, waterfall примерно `76.128` Godot units. Следовательно, все пять камер находятся над rendered terrain; visual obstruction принадлежит placements/WMO/composition, а не terrain height.
+
+Waterfall XZ сначала давал `no_intersection`, хотя tile `30_49` был available, полностью загружен, имел `control_splat_cache` quality mesh и LOD0 mesh, а probe находился внутри mesh AABB. Ray со смещением `2.0` units пересёк тот же mesh на высоте `113.872`; точная XZ попала на triangle seam/edge numerical miss. Probe теперь сообщает `sampled_nearby`, distance и source tile вместо ложного streaming ownership gap. `--require-all` остаётся строгим режимом для действительно неснятых точек.
+
+## Camera occluder diagnostic
+
+Scene-tree placement composition проверяется transformed AABB без изменения renderer:
+
+```powershell
+godot --headless --path . --script res://src/tools/probe_render_camera_occluders.gd -- --wait 3

+    A --> I[Segment intersection test]
+    S --> I
+    P --> J[JSON occluder report]
+    I --> J
+```
+
+Ни одна из пяти камер не находится внутри опубликованной scene-tree geometry. Terrain-overview segment пересекает четыре Stormwind WMO groups, large-WMO segment — три Goldshire Inn groups, waterfall segment — liquid surface; ADT boundary и dense-M2 segments не пересекают placement AABB. Поэтому прежнее визуальное впечатление «камера внутри WMO/placements» не подтверждается. Основной paired gap сейчас — неточно воспроизведённые manual look direction/target/FOV reference-кадров: например, автоматический Goldshire target направляет луч через фасад внутрь WMO, тогда как reference был вручную скадрирован на весь фасад. Probe охватывает только scene-tree MeshInstance/MultiMesh; RID-only instances не имеют доступного semantic path и явно исключены из coverage.
+
+## Empirical FOV sweep
+
+В build 12340 `GetCVar("cameraFoV")` возвращает `nil`, а `/console cameraFoV` и `ConsoleExec("cameraFoV")` не выдают значения. Поэтому capture tool поддерживает additive `--camera-fov`, а comparator — `--only`, позволяющий ограничить sweep одним reference checkpoint.
+
+```mermaid
+flowchart LR
+    F[Candidate vertical FOV] --> C[Dedicated checkpoint camera]
+    C --> P[Filtered checkpoint PNGs]
+    R[One original-client reference] --> D[Perceptual comparator --only]
+    P --> D
+    D --> M[Ranked metrics]
+```
+
+Первый sweep обнаружил capture defect: разные FOV иногда создавали одинаковые hashes, потому что scene camera могла перехватить viewport после входа в tree. Capture теперь вызывает `camera.make_current()` после добавления world и перед каждым checkpoint. После исправления ADT-boundary ranking стал: `26° → 0.079588`, `38° → 0.079633`, `50° → 0.084353`, `62° → 0.088360`, `86° → 0.097993` mean error. Plateau `26–38°` и несовпавший changed-pixel optimum показывают доминирование manual look direction/framing; эти данные не обосновывают изменение нормативного manifest FOV `62°`. Для настоящей калибровки reference capture должен сохранять воспроизводимые yaw/pitch/zoom или независимый projection fixture.

+# ADR 0001: Canonical world coordinate contract
+
+- Status: Accepted for M01 contract implementation
+- Date: 2026-07-13
+- Work packages: `M01-FND-COORDS-001`, corrected by `M01-FND-COORD-TILE-AXIS-002`
+- Decision owners: M01 foundation/integration owners
+
+## Context
+
+OpenWC currently performs coordinate conversion in native ADT/WDT loaders,
+`StreamingWorldLoader`, sky, player and renderer diagnostic scripts. The same
+numbers are frequently carried in `Vector3` or dictionaries, so the coordinate
+space is implicit. Existing names also mix ADT filename indices, renderer X/Z
+indices and MDDF/MODF placement fields.
+
+M00 recorded five positions observed in WoW 3.3.5a build 12340. They verify the
+current client-position to Godot-position arithmetic within `0.002` yard, but
+they do not define a cross-layer contract and do not prove camera composition
+or visual parity.
+
+Independent references agree on a 64 by 64 ADT grid and an approximately
+`533.3333` yard tile size. They do not all use the word “canonical” for the same
+axis order. OpenWC therefore needs names tied to observable formats instead of
+adopting an internal convention from one reference project.
+
+## Decision
+
+### Canonical position
+
+`CanonicalWowWorldPosition(X, Y, Z)` preserves the numeric X/Y/Z order used by
+the WoW client, movement protocol and TrinityCore/AzerothCore world positions.
+X and Y are horizontal; Z is height. Units are WoW yards.
+
+`ServerWorldPosition` is a distinct type but converts component-for-component
+to canonical. The type boundary prevents a server record from being passed
+directly to renderer code and leaves room for adapter validation without a
+silent axis swap.
+
+### World extent and ADT indices
+
+The contract uses:
+
+```text
+ADT_TILE_SIZE_YARDS = 1600 / 3
+ADT_TILES_PER_MAP_AXIS = 64
+WOW_WORLD_HALF_EXTENT_YARDS = 32 * ADT_TILE_SIZE_YARDS
+
+tileX = floor(32 - canonical.Y / ADT_TILE_SIZE_YARDS)
+tileY = floor(32 - canonical.X / ADT_TILE_SIZE_YARDS)
+```
+
+`AdtTileCoordinate(tile_x, tile_y)` always means the indices in
+`Map_tileX_tileY.adt`. Results are intentionally not clamped: the exact
+south-east extent produces index 64 and remains diagnosable as out of bounds.
+Normal valid indices are 0 through 63.
+
+An `AdtTileLocalPosition` is measured east and south from the tile's
+north-west corner. Filename `tile_x` and MCNK `chunk_x` grow east; filename
+`tile_y` and MCNK `chunk_y` grow south, with valid indices 0 through 15. These
+direction names avoid pretending that ADT file axes are Godot X/Z axes.
+
+### ADT placement fields
+
+MDDF/MODF position fields are represented in on-disk X/height/Z order:
+
+```text
+adt.X      = halfExtent - canonical.X
+adt.height = canonical.Z
+adt.Z      = halfExtent - canonical.Y
+```
+
+Model-local MDDF/MODF Euler corrections are not world orientation. They remain
+outside this contract until a placement-orientation package has format- and
+model-specific fixtures.
+
+### Godot renderer basis
+
+The compatibility renderer keeps one Godot unit equal to one WoW yard and uses
+Y-up coordinates from the north-west map extent:
+
+```text
+godot.X = halfExtent - canonical.Y  # east
+godot.Y = canonical.Z               # up
+godot.Z = halfExtent - canonical.X  # south
+```
+
+`GodotWorldPosition` contains scalars rather than `Vector3`. A scene/render
+adapter may construct `Vector3` only at its boundary.
+
+### World yaw
+
+Server/canonical yaw zero faces increasing WoW X; positive yaw turns toward
+increasing WoW Y. In the mapped Godot basis, Godot forward `-Z` and positive
+Y-axis yaw produce the same numeric world angle. Mapper conversions therefore
+normalize the value to `[-PI, PI)` without adding an offset.
+
+This identity applies to world-facing yaw only. It does not apply to M2/WMO
+asset axes or placement Euler triples.
+
+### Contract version 2 correction evidence
+
+Contract version 1 incorrectly calculated filename `tile_x` from canonical X
+and `tile_y` from canonical Y. The private WotLK corpus contains the observed
+Elwynn point in `Azeroth_31_49.adt`, SHA-256
+`18185B5FAC9566D9C57A9C19ABD75F108370D1795639B6077167C0EFD3672FAE`; the
+transposed `Azeroth_49_31.adt` does not exist. Raw MCNK headers in that file
+show `indexX` decreasing world Y (east) and `indexY` decreasing world X (south).
+OpenRealm independently calculates filename X from world Y and filename Y from
+world X. Contract version 2 corrects the formulas before any consumer migration.
+
+### Enforced conversion boundaries
+
+GDScript production consumers use `CoordinateMapper` for canonical/Godot and
+Godot/ADT tile-local conversion. `StreamingWorldLoader`, player spawn/terrain
+sampling, sky/area lookup and terrain diagnostics may construct `Vector3` only
+at their scene/tool boundary.
+
+The native ADT/WDT parser path retains one equivalent formula definition in
+`src/native/src/wow_chunk_reader.h`; worker parsers cannot call GDScript. The
+M00 renderer calibration keeps one independent formula as a test oracle so a
+shared mapper defect cannot make both implementation and evidence agree.
+Repository verification rejects additional world-center, world/tile or named
+WoW/Godot formulas outside those explicit exceptions. Model-local M2/WMO basis
+transforms are separate format contracts and are not classified as world-space mapping.
+
+## Alternatives considered
+
+### Make renderer coordinates canonical
+
+Rejected because protocol, database and ADT adapters would silently inherit a
+presentation-specific offset and Y-up basis.
+
+### Adopt WoWee's internal canonical axis names unchanged
+
+Rejected because that reference swaps server X/Y into its chosen north/west
+ordering. OpenWC preserves observable client/server field names and makes the
+render/ADT transformations explicit instead.
+
+### Use `Vector3` plus comments
+
+Rejected because comments cannot prevent server, ADT and Godot values from
+being passed across the wrong boundary.
+
+### Generic vector-space or matrix framework
+
+Rejected as unnecessary complexity for fixed affine transforms and integer
+grid ownership rules.
+
+## Consequences
+
+- Network and server-data adapters can expose typed positions without knowing
+  Godot.
+- Renderer consumers must explicitly map and then create Godot vectors at their
+  own boundary.
+- ADT filename indices can no longer be confused with renderer X/Z tile names.
+- GDScript world/tile consumers use mapper APIs; renderer distance and LOD math
+  remains ordinary Godot-space geometry.
+- Native ADT/WDT loaders share one boundary formula and the M00 calibration
+  keeps one independent non-production oracle.
+- New manual axis conversions are review/test violations enforced by the
+  repository-wide source gate.
+- Persisted schemas are unchanged. Future serialized positions must include an
+  explicit coordinate-space/version discriminator.
+
+## Verification
+
+- Five M00 build-12340 client camera positions map to the recorded Godot
+  checkpoints within `0.002` yard.
+- Server, ADT placement, Godot and tile-local conversions round-trip.
+- Exact center, tile, chunk and world-extent boundaries have explicit tests.
+- The observed Elwynn position resolves to the real `Azeroth_31_49.adt` file;
+  MCNK `(0,0)` to `(15,15)` origins confirm X-east and Y-south chunk growth.
+- World-yaw normalization and round-trip cases cover cardinal angles and wrap.
+- Direct Godot/ADT tile-local conversions round-trip and production consumers
+  are checked by `verify_coordinate_conversion_boundaries.gd`.

+# ADR 0002: Separate domain identity namespaces

+- Status: Accepted for M01 contract implementation
+- Date: 2026-07-13
+- Work package: `M01-FND-DOMAIN-IDENTITIES-001`
+- Decision owners: M01 foundation/integration owners
+
+## Context
+
+OpenWC must relate authored content, runtime objects, WoW protocol objects and
+TrinityCore/AzerothCore rows. All four domains can expose an integer or string,
+but their identity lifetimes and collision rules are different. A raw `int`, a
+generic `id` field or one universal ID class would allow an entity sequence to
+be persisted as content identity, a database entry to be sent as a wire GUID,
+or equal entry numbers from different tables to collide.
+
+The Content Project requires stable references before server entries are
+allocated. Runtime entities require cheap session-local identity even when no
+server object exists. WoW 3.3.5a GUIDs carry opaque 64 wire bits whose semantic
+decomposition must be established by protocol fixtures. Server templates use
+numeric entries scoped by an adapter/table namespace.
+
+## Decision
+
+### ContentId
+
+`ContentId` stores canonical lowercase UUID text in the `8-4-4-4-12` shape.
+It is the only identity in this decision intended for stable authored-content
+references and serialization. Construction normalizes whitespace and letter
+case; `is_valid()` reports malformed input without crashing an import.
+
+The value validates text shape, not UUID version or variant bits. A future
+Content Project allocator chooses the UUID generation policy and owns duplicate
+detection. Every persisted schema that contains a `ContentId` still declares
+its own schema version and field migration.
+
+### EntityId
+
+`EntityId` stores a positive integer allocated by one runtime session owner.
+It is valid only inside that session and must not be persisted as content,
+protocol or server identity. Sequence reuse policy belongs to the future entity
+registry, not the value object.
+
+### WowGuid
+
+`WowGuid` stores opaque `high_32_bits` and `low_32_bits` integers. Each word is
+validated against `0..0xffffffff`, preserving every unsigned wire bit without
+combining it into GDScript's signed 64-bit integer. The all-zero value remains
+an observable protocol sentinel and receives no gameplay interpretation here.
+
+High-type masks, packed-GUID codecs and object-kind extraction are explicitly
+deferred to the build-12340 protocol package and require packet fixtures.
+
+### ServerEntryId
+
+`ServerEntryId` stores a positive numeric entry together with a normalized,
+non-empty adapter/table namespace. Equal numbers in different namespaces are
+different identities. Mapping a server entry to a `ContentId` is explicit
+adapter/snapshot data; neither value derives the other.
+
+### Equality and keys
+
+The types expose domain-named `equals` methods because `RefCounted` `==`
+compares object references. Stable keys are available only where their lifetime
+allows them: `ContentId.to_key()`, `WowGuid.to_hex_string()` and
+`ServerEntryId.to_key()`. `EntityId` exposes only `to_debug_key()` to discourage
+persistence.
+
+## Alternatives considered
+
+### One generic `Id<T>` abstraction
+
+Rejected because GDScript has no compile-time generic type distinction and the
+shared API would obscure different validation, lifetime and persistence rules.
+
+### Use strings everywhere
+
+Rejected because prefixes are a convention rather than a type boundary and
+would still permit accidental cross-layer assignment.
+
+### Store WowGuid in one integer
+
+Rejected because unsigned 64-bit GUIDs can exceed GDScript's positive signed
+integer range. Split words preserve the wire representation losslessly.
+
+### Use server entries as ContentId
+
+Rejected because entries are allocated by a particular backend/table, can
+collide between namespaces and do not exist while authoring offline content.
+
+### Generate UUIDs inside ContentId
+
+Rejected because randomness/allocation is a side effect requiring duplicate,
+fixture and deterministic-build policy. This value object only normalizes and
+validates an allocator-provided value.
+
+## Consequences
+
+- Cross-layer contracts must name the identity type they accept.
+- Content references remain stable before and after server deployment.
+- Runtime entity registries need explicit mappings to wire GUIDs/content IDs.
+- Server adapters must supply a namespace and maintain entry-to-content maps.
+- Malformed external values remain representable long enough for adapters to
+  produce diagnostics, but consumers must call the relevant validation method.
+- Additional typed IDs such as map, spell, item and quest remain separate
+  follow-up contracts rather than aliases of these four values.
+
+## Verification
+
+- UUID normalization, shape validation and value equality are fixture-tested.
+- Zero/positive session sequences establish `EntityId` validity boundaries.
+- Maximum unsigned GUID words round-trip to exactly sixteen hexadecimal digits;
+  overflow is rejected and zero remains detectable.
+- Equal server entry numbers in creature/gameobject namespaces do not compare equal.
+- Dependency search verifies that identity values do not inherit Node/Resource
+  or expose `Vector3`.

+# ADT Water Load Pipeline State
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | M03 / `M03-RND-ADT-WATER-LOAD-PIPELINE-001` |
+| Owners | ADT water pending FIFO/dedupe, active task IDs and worker-safe result mailbox |
+| Last verified | Worktree `work/sindo-main-codex/m03-adt-water-load-pipeline`, 2026-07-17 |
+| Profiles/capabilities | ADT MH2O/MCLQ water loading; profile-independent state |
+
+## Purpose
+
+Own the cross-frame and cross-thread bookkeeping for asynchronous ADT water
+loads outside `StreamingWorldLoader`: FIFO requests, queued-key deduplication,
+opaque active task IDs and parsed-result delivery. The loader retains task
+execution, parsing, budgets, stale-result decisions and scene finalization.
+
+## Non-goals
+
+- Start, cancel or wait WorkerThreadPool tasks.
+- Instantiate `ADTLoader` or interpret MH2O/MCLQ data.
+- Select concurrency limits or consume render permits.
+- Create, attach or free Nodes, Meshes, materials or RIDs.
+- Change liquid visuals, coordinates, tile acceptance or loaded-state timing.
+

+```
+
+## Lifecycle/state
+
+A tile request progresses through `Absent`, `Queued`, `Active` and
+`ResultReady`; the loader wait/completion returns bookkeeping to `Absent` before
+validating/attaching the result. Queued tile release cancels only `Queued`.
+Active work is not interrupted; a later stale result is drained and discarded.
+
+```mermaid
+stateDiagram-v2
+    [*] --> Absent
+    Absent --> Queued: accepted enqueue
+    Queued --> Absent: pending cancellation or invalid dequeue
+    Queued --> Active: loader starts task
+    Active --> ResultReady: worker publishes result
+    ResultReady --> Absent: loader waits and completes task
+    Queued --> Absent: clear
+    Active --> Absent: clear bookkeeping only
+    ResultReady --> Absent: clear
+```

+
+## Ownership, threading and resources
+
+- Main thread owns pending and active-task collection mutation.
+- Worker threads may call only `publish_result`; result observe/pop/clear also lock.
+- Parsed water Dictionary identity is retained until main-thread pop.
+- Loader owns WorkerThreadPool task lifetime and must wait before orderly shutdown clear.
+- Loader owns tile states and the tile subtree; `AdtWaterSceneFinalizer` performs
+  the main-thread ADTBuilder call and attachment without retaining Nodes.
+- `clear` cannot cancel a worker; post-reset publication becomes a stale result
+  and is discarded because no active task/tile ownership remains.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty/duplicate request | Enqueue guards | Reject unchanged | Contract verifier | Correct caller state |
+| Tile removed while queued | Loader release | Remove matching pending requests | Source/lifecycle verifier | Reload can enqueue later |
+| Tile removed while active | Loader stale check after result | Wait task, remove active ID, discard result | Existing metrics | Reload can enqueue later |
+| Parser unavailable/empty | Worker publishes empty Dictionary | Loader marks `water_loaded` without Node | Existing behavior | Future tile reload |
+| Path changed | Loader compares result path | Discard after task completion | Source regression | Current tile can request again |
+| Shutdown | Loader snapshots/waits active IDs | Clear all bookkeeping/results | Shutdown/source verifier | New loader starts empty |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| `enable_water` | Loader setting | Quality/custom | Yes | Gates enqueue/process, unchanged |
+| `max_concurrent_water_tasks` | Loader setting | Quality/custom | Yes | Bounds active tasks outside state |
+| `water_finalize_ops_per_tick` | Loader setting | Quality/custom | Yes | Bounds result pops via scheduler |
+
+## Persistence, cache and migration
+
+No state is serialized or cached. ADT source/cache formats and liquid material
+versions are unchanged; no migration or rebuild is required.
+
+## Diagnostics and observability
+
+- `total_load_count` preserves the prior pending-plus-active `water` metric.
+- Snapshot exposes FIFO tile/path, sorted active keys and result tile/path only.
+- Parsed liquid payloads, Nodes and task internals are not exposed.
+- No logs or correlation IDs are introduced.
+
+## Verification
+
+- `verify_adt_water_load_pipeline_state.gd`: invalid/dedupe/FIFO behavior,
+  active IDs, payload identity, real Thread publication, pending cancellation,
+  clear, detached diagnostics, loader boundaries and bounded timing.
+- Existing material/shutdown/facade/streaming regressions cover adjacent behavior.
+- Fidelity evidence is preservation of current scheduling/finalize transitions;
+  no MH2O/MCLQ visual or original-client parity claim is made.
+- Performance budget: 100 cycles of 256 request/task/result transitions under 1 second.
+
+## Extension points
+
+- ADT parse execution can later move behind a parser/job adapter without changing state.
+- Water scene materialization is now delegated to `AdtWaterSceneFinalizer`,
+  independently of this async bookkeeping service.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| ADT water load pipeline state | Implemented extraction | FIFO/task/thread/source/timing verifier | Asset-backed traversal/leak evidence pending |
+| ADT liquid parsing | Existing/loader-owned adapter | Native ADTLoader and dry-run paths | MH2O/MCLQ fidelity fixtures pending |
+| Water scene finalization | Implemented extraction | Dedicated synthetic scene/ownership verifier | Asset-backed traversal/hitch evidence pending |
+
+## Known gaps and risks
+
+- `clear` intentionally does not interrupt active WorkerThreadPool work.
+- Result payload Dictionaries are retained by reference and must not be mutated after publication.
+- Result availability and pop use separate mutex acquisitions; one serialized
+  main-thread consumer preserves ordering, but the API is not a multi-consumer queue.
+- No proprietary liquid corpus, traversal/leak run, p95/p99 or paired capture is included.

+| Target/work package | M03 / `M03-RND-ADT-WATER-SCENE-FINALIZER-001` |
+| Owners | Main-thread ADT water subtree build, attach and optional editor ownership |
+| Last verified | Worktree `work/sindo-main-codex/m03-adt-water-scene-finalizer`, 2026-07-17 |
+| Profiles/capabilities | Existing ADT MH2O/MCLQ scene output; profile-independent adapter |
+
+## Purpose
+
+Provide one liquid-specific main-thread boundary for converting parsed ADT
+water data through the existing `ADTBuilder`, attaching the resulting `Water`
+subtree to a caller-owned tile root and assigning optional persisted Editor
+ownership. The service is stateless and retains no Node or Resource.
+
+## Non-goals
+
+- Parse or validate MH2O/MCLQ binary structures.
+- Replace ADTBuilder geometry, material or coordinate calculations.
+- Own water request/task/result state, permits or concurrency.
+- Validate tile/path/root freshness beyond receiving a valid root.
+- Mark `water_loaded`, enable water or remove water subtrees.
+
+## Context and boundaries

+```
+
+Allowed dependencies are `ADTBuilder` and Godot Node/mesh types needed to adopt
+its output. WorkerThreadPool, scheduler, tile-state dictionaries, facade,
+gameplay, network and editor plugin packages are forbidden.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `attach_water_scene(water_data, tile_origin_godot_units, tile_root, editor_owner)` | Command/query | Build and attach one existing-format water subtree | Renderer main thread; returned Node is borrowed for tile lifetime | Empty data, invalid root or dry build returns null without attachment |
+
+`editor_owner` is optional. When supplied it must be an ancestor suitable for
+Godot `Node.owner`; ownership is recursively assigned to the generated subtree.
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|

+| Input | Optional edited scene root | Loader Editor policy | Finalizer | SceneTree-owned borrowed Node | One call |
+| Output | Attached `Water` Node3D or null | Finalizer | Loader/SceneTree | Tile root owns attached Node | Tile subtree lifetime |
+
+Side effects are limited to ADTBuilder mesh/material creation, `add_child` and
+optional recursive `Node.owner` assignment. No cache, filesystem, task or tile
+state is mutated.

+```
+
+## Ownership, threading and resources
+
+- The method is main-thread only because it creates Mesh/Material/Node objects
+  and mutates the SceneTree.
+- `ADTBuilder` owns temporary construction. It frees an empty `Water` root and
+  returns null for dry/invalid liquid geometry.
+- After `add_child`, the caller's tile subtree owns the returned Water root and
+  all MeshInstance children; the finalizer retains no references.
+- Optional editor ownership affects serialization ownership only and does not
+  replace SceneTree lifetime ownership.
+- Parsed Dictionaries are borrowed and not mutated.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty parsed data | Input guard | Return null, no builder call | Contract verifier | Loader preserves existing loaded timing |
+| Missing/freed tile root | Input guard | Return null, no scene mutation | Contract verifier | Stale-result validation normally rejects earlier |
+| Dry or malformed liquid arrays | ADTBuilder returns null | No attachment | Builder/shutdown regression | Reload after corrected source |
+| Tile/path stale | Loader before call | Finalizer is not invoked | Existing loader behavior | Current tile may enqueue again |
+| Shutdown/cancellation | Loader drains/cancels before call | No retained finalizer work | Shutdown verifier | New loader starts stateless |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| `enable_water` | Loader setting | Quality/custom | Yes | Gates both caller paths; not owned here |
+| `water_finalize_ops_per_tick` | `1` | Quality/custom | Yes | Budgets async calls before finalizer |
+| `editor_persist_generated_nodes` | `false` | Editor only | Yes | Supplies or omits editor owner |
+
+## Persistence, cache and migration
+
+The service writes no files and changes no cache/resource schema. Existing ADT,
+terrain cache and liquid material versions remain valid; no rebuild or migration
+is required. Persisted Editor ownership follows the loader's existing opt-in.
+
+## Diagnostics and observability
+
+- Logs: none; existing loader/builder diagnostics remain authoritative.
+- Metrics: no independent counters; existing water queue/finalize metrics remain.
+- Debug views: generated `Water/Liquid_<id>` names remain unchanged.
+- Correlation IDs: tile/path correlation stays in loader pipeline state.
+
+## Verification
+
+- `verify_adt_water_scene_finalizer.gd`: empty/invalid/dry guards, one-cell
+  geometry, attachment, recursive owner, loader delegation and bounded timing.
+- `verify_adt_water_load_pipeline_state.gd`: adjacent async ownership and loaded timing.
+- Renderer material and shutdown verifiers cover material construction and dry-root cleanup.
+- Fidelity evidence is the unchanged ADTBuilder implementation and unchanged two
+  loader call positions; no new original-client liquid parity claim is made.
+- Performance budget: 100 empty calls under one second.
+
+## Extension points
+
+- A future liquid renderer may replace the internal builder only after paired
+  MH2O/MCLQ fixtures establish equivalent geometry/material behavior.
+- Removal/eviction remains ordinary tile subtree ownership and needs no parallel API.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| ADT water scene finalization seam | Implemented extraction | Synthetic geometry/attach/owner/source verifier | Asset-backed traversal and hitch metrics pending |
+| ADT liquid geometry/materials | Existing implementation | ADTBuilder/material/checkpoint evidence | MH2O/MCLQ and original-client parity incomplete |
+| Async water scheduling | Existing extracted state | Water pipeline verifier | Active worker interruption remains loader-owned |
+
+## Known gaps and risks
+
+- The service intentionally wraps the existing Dictionary-based ADTBuilder boundary.
+- It does not verify that `editor_owner` is an ancestor; the loader supplies the
+  edited scene root under the existing policy.
+- Mesh/material creation remains synchronous main-thread work behind the existing permit.
+- No proprietary liquid corpus, long traversal leak run, p95/p99 or paired capture is included.

+Appearance replacement removes the old root from the scene immediately and

+completion cannot publish a replaced model.

+
+## Ownership, threading and resources
+
+- The runtime scene owns one appearance presenter on `Visual` and one animation
+  presenter below it.
+- The appearance presenter exclusively owns the generated `CharacterModel`
+  subtree; imported shared resources remain Godot-owned.
+- The animation presenter borrows an AnimationPlayer reference until rebind or
+  subtree replacement; the player scene orders rebind through the ready signal.
+- Loading, node mutation, bounds calculation, outfit setup and playback occur
+  on the main thread. There are no workers, locks, RIDs or cancellation tokens.
+- The player controller owns neither model resources nor animation state.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty model path | Load guard | Clears old root and returns `false` | Contract regression | Configure a path and retry |
+| Invalid model resource | Failed PackedScene cast | Remains empty | Named warning with path | Correct/extract asset and retry |
+| Replaced deferred completion | Root identity check | Stale completion ignored | Replacement regression | No action required |
+| Missing DBC/outfit inputs | Existing resolver returns false/empty | Base model remains visible | Existing resolver diagnostics | Restore extracted inputs and reload |
+| Missing AnimationPlayer | Recursive discovery returns null | Presenter becomes unbound | Contract return/read state | Bind a root with animations |
+| Missing candidate animation | Candidate selection returns empty | Current playback unchanged | Verifier/source diagnostics | Extend verified candidate policy later |
+
+There is no background load cancellation. Replacement is the recovery path and
+invalid model state is explicit through the return value and null read model.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Character model | Human male sandbox GLB | Current sandbox | Before reload | Model scene input |
+| Character class ID | `1` | Current sandbox | Before reload | Starter outfit lookup |
+| Uniform scale | `1.0` | Current sandbox | Before reload | Character root scale |
+| Yaw offset | `90` degrees | Current sandbox | Before reload | Imported model correction |
+| Extracted content root | `res://data/extracted` | Local content | Per load override | DBC/item texture input |
+| Animation blend | `0.15` seconds | Current sandbox | Before bind/transition | Playback cross-fade/default blend |
+| Stationary candidates | `Stand`, then `Idle` | Current sandbox | Fixed | Exact then substring selection |
+| Moving candidates | `Run`, then `Walk` | Current sandbox | Fixed | Exact then substring selection |
+
+## Persistence, cache and migration
+
+Presenter state is transient. No saved settings, user profile, database schema
+or cache format changes. Existing scene paths remain
+`ThirdPersonPlayer/Visual` and add only `Visual/AnimationPresenter`; model and
+extracted-data paths retain their defaults. Moving the model exports from the
+player node to `Visual` is a scene-authoring ownership change, not persisted
+runtime data migration.
+
+## Diagnostics and observability
+
+- Logs: invalid model path warns with the responsible presenter and path.
+- Read models: current character root, animation binding and active name.
+- Tests: dedicated verifier reports appearance, animation, scene and player boundaries.
+- Metrics/correlation IDs: not applicable to this synchronous sandbox presenter.
+
+## Verification
+
+- Unit/contract: synthetic model fixture verifies load, scale, yaw, grounding,
+  compositor composition, ready signal, replacement and empty-model clearing.
+- Animation: synthetic libraries verify nested discovery, exact and substring
+  candidate selection, loop policy, blend configuration and duplicate suppression.
+- Boundary: player source contains no model loading, outfit, bounds or
+  AnimationPlayer logic; appearance and animation dependencies remain separate.
+- Integration: Eastern Kingdoms, Kalimdor and player regression scenes compose
+  both presenters; existing input/movement/terrain/camera tests remain required.
+- Fidelity evidence: only preservation of the current sandbox defaults and
+  selection rules. No build-12340 appearance or animation parity is claimed.
+- Performance: one synchronous model composition per load and constant-time
+  locomotion calls except on state transition; asset streaming remains future work.
+
+## Extension points
+
+- Replace starter outfit inputs with a versioned appearance/equipment snapshot.
+- Replace boolean locomotion input with a typed presentation state after
+  movement/network contracts define walk, run, jump, fall, swim, mount and emotes.
+- Add asynchronous/preloaded model providers behind the appearance command
+  without moving resource loading back into gameplay.
+- Add verified animation IDs/variation policy after build-12340 fixtures exist.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Independent appearance composition | Implemented | Synthetic fixture and three scene wirings | Integrator target update |
+| Independent locomotion animation | Implemented | Exact/fallback/loop/blend regression | Add typed presentation state later |
+| Current starter outfit | Partial | Existing resolver reused unchanged | Needs extracted DBC fixture and client comparison |
+| Current skin/geoset composition | Partial | Existing components reused | Full equipment/customization fidelity incomplete |
+| Build-12340 animation semantics | Planned | No original-client fixture | Capture animation IDs/transitions/timing |
+| Runtime equipment/network updates | Planned | No snapshot contract | M08/M09/M12 work |
+
+## Known gaps and risks
+
+- Model loading remains synchronous and can hitch when not preloaded.
+- Exact appearance, equipment, animation choice, playback speed and blending are unverified.
+- The moving input is a sandbox threshold boolean, not authoritative locomotion state.
+- The first descendant AnimationPlayer wins; multi-player imported scenes need a
+  more explicit binding contract if they appear.
+- Existing geoset/compositor/outfit implementations retain their own fidelity gaps.

+
+## Lifecycle/state
+
+The module is stateless. Each call reads immutable scalar inputs and returns a
+new value object. There is no initialization, shutdown, cancellation or retry
+state machine.
+
+## Main sequence
+
+No cross-layer asynchronous sequence occurs inside this module. Producers parse
+or validate their external format first, call the mapper synchronously, and
+then pass only typed results across the next boundary.
+
+## Ownership, threading and resources
+
+- Value objects own only scalar fields and, for chunks, one immutable tile reference.
+- Callers own returned `RefCounted` references.
+- Methods do not mutate inputs or shared state and are safe for worker use.
+- No Node, RID, file, socket, database or cache resource is acquired.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Tile/chunk outside standard grid | `is_within_map_grid()` | Unclamped indices are preserved | Caller reports source and map context | Reject or apply explicit map policy |
+| Tile-local value outside half-open tile | Consumer boundary validation | Value is preserved | Caller reports source coordinate | Recompute ownership or reject malformed input |
+| Null value object | Static typing/call failure | Programming contract violation | GDScript error with call site | Fix producer; no fallback value |
+| NaN/infinite scalar | Adapter validation | Arithmetic propagates invalid value | Adapter must report source field | Reject malformed external input |
+
+There is no cancellation because every conversion is constant-time scalar math.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Contract version | 2 | All | No | Corrected filename/chunk axes in ADR 0001 |
+| Godot units per WoW yard | 1 | `Blizzlike335` and current tools | No | Preserves current renderer scale |
+| ADT grid | 64 tiles/axis, 16 chunks/tile | WotLK 3.3.5a | No | Defines index and boundary math |
+
+## Persistence, cache and migration
+
+Production code adds no persisted format, cache or migration. Test schema 1 in
+`coordinate_golden_points.json` persists explicit source provenance, coordinate
+contract version 2, tolerances, source-space values and expected outputs. It
+contains no proprietary bytes, database dump or original-client image. Existing
+dictionaries, native `Vector3` payloads and renderer conversion helpers remain compatible.
+Consumer migration is ordered after this contract and must remove old manual
+conversions only after its producer/consumer tests pass.
+
+Any future serialized coordinate must store a schema version and explicit space;
+raw three-number arrays are not an accepted new persistence contract.
+
+## Diagnostics and observability
+
+- Logs: none in production mapper.
+- Metrics: none; conversion cost is constant and outside frame-budget concern.
+- Debug views: headless contract probe prints one PASS summary.
+- Correlation IDs: supplied by external adapters if an invalid source is reported.
+
+## Verification
+
+- Unit/contract tests: `src/tools/verify_coordinate_mapper.gd`.
+- Cross-source golden test: `src/tools/verify_coordinate_golden_fixtures.gd`.
+- Boundary enforcement: `src/tools/verify_coordinate_conversion_boundaries.gd`.
+- Server-spawn renderer contract: `src/tools/verify_server_spawn_renderer.gd`
+  validates the dedicated manifest against the same pinned fixture before GUI capture.
+- Integration/E2E: sky, player spawn, streamer, terrain probe and the extracted
+  `AdtTerrainQuery` use mapper boundaries;
+  `StreamingFocus` provides typed renderer focus, and the pinned AzerothCore
+  Human Warrior spawn is captured in the Eastern Kingdoms renderer at ADT
+  `(32,48)`, chunk `(3,12)`.
+- Fidelity evidence: five build-12340 camera positions from the M00 manifest map
+  within `0.002` yard; a pinned AzerothCore human-warrior spawn and one raw MCNK
+  header observation independently confirm tile `(32,48)` and chunk `(3,12)`;
+  independent reference formulas are recorded in ADR 0001.
+- Performance budgets: constant-time arithmetic; no scene or file access.
+- Manual diagnostics: not required for the pure contract; renderer checkpoints
+  are required when consumers migrate.
+
+## Extension points
+
+- Add typed map IDs around positions without changing axis semantics.
+- Add a format-specific placement-orientation adapter with its own fixtures.
+- Add serialization only with explicit space/version fields and migrations.
+- Add consumer adapters that construct engine-native vectors at their boundary.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Canonical/server/Godot position mapping | Implemented | Headless round-trip, five M00 golden points and migrated GDScript consumers | Network/server adapters remain future consumers |
+| ADT placement mapping | Implemented | Synthetic/direct round-trip fixtures | Compare native parsed placements during migration |
+| ADT tile/local/chunk ownership | Implemented | Center/extent boundaries, raw `Azeroth_31_49.adt` evidence and direct Godot adapter round-trip | Native parser remains explicit boundary |
+| World-facing yaw mapping | Implemented | Cardinal/wrap round-trip fixtures | Placement Euler remains separate |
+| Scene-free production contract | Implemented | Source boundary, headless tests and repository-wide conversion gate | Maintain gate with new consumers |
+| Cross-source coordinate fixture | Implemented | Pinned AzerothCore spawn, raw ADT MCNK metadata and five build-12340 points pass one headless verifier | Add live adapter/renderer integration |
+| TrinityCore populated spawn equivalence | Not verified | The base development schema has no pinned populated row used by this fixture | Pin and verify a TDB snapshot before claiming parity |
+| Visual/server-spawn integration | Implemented | Dedicated manifest/verifier plus cold/warm GUI capture of the mapped AzerothCore spawn | This is coordinate/renderer integration evidence, not original-client visual parity |
+
+## Known gaps and risks
+
+- Native ADT/WDT parsing retains one shared boundary formula because worker
+  parsers cannot call GDScript; the gate prevents additional definitions.
+- Contract version 1 briefly transposed ADT filename/chunk axes; version 2 fixes
+  the defect before any consumer migration.
+- MDDF/MODF rotation comments and implementations disagree across existing paths;
+  this package deliberately does not generalize them into world yaw.
+- Finite-number validation belongs to external format adapters and is not yet implemented.
+- Arithmetic agreement does not prove terrain, placement, camera direction or visual parity.
+- The golden server row is verified against pinned AzerothCore data only; no
+  TrinityCore equivalence claim is made without a pinned populated TDB snapshot.

+## Purpose
+
+Provide non-interchangeable, scene-free identity values for authored content,
+runtime entities, WoW wire objects and namespaced server entries. Each value
+states its lifetime and serialization rules instead of exposing a generic `id`.
+
+## Non-goals
+
+- Allocating, reserving or globally registering IDs.
+- Parsing packet bytes or server database rows.
+- Mapping GUID high types or server entries to gameplay object kinds.
+- Defining Content Project, snapshot or replay schemas.
+- Replacing future typed map/spell/item/quest/display/sound IDs.
+
+## Context and boundaries

+    Raw[Raw int or string] -. forbidden across boundary .-> Consumers
+```
+
+Allowed dependencies:
+
+- GDScript scalar/string operations and `RefCounted` lifetime;
+- callers in content, gameplay, network and server adapter layers.
+
+Forbidden dependencies:
+
+- Node, Resource, SceneTree, renderer and UI state;
+- packet buffers, SQL connections or database table implementations;
+- implicit conversion between identity namespaces;
+- random/global allocation inside the value objects.

+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|

+
+## Data flow
+
+```mermaid
+flowchart TD
+    ContentSource[Authored document] -->|UUID text| ContentId
+    ServerRow[Backend table row] -->|adapter + table + entry| ServerEntryId
+    Packet[World packet] -->|high/low wire words| WowGuid

+    WowGuid --> RuntimeMap[Explicit runtime mapping]
+    EntityId --> RuntimeMap
+    DeployMap --> Snapshot[Versioned snapshot/change set]
+    RuntimeMap --> WorldState[Session world state]
+```
+
+## Lifecycle/state
+
+```mermaid
+stateDiagram-v2
+    state ContentIdentity {
+        [*] --> Parsed
+        Parsed --> Persisted: valid ContentId
+        Persisted --> Referenced
+    }
+    state RuntimeIdentity {
+        [*] --> Allocated
+        Allocated --> Active
+        Active --> Released: session owner removes entity
+        Released --> [*]

+        Observed --> Mapped: WowGuid or ServerEntryId
+        Mapped --> Stale: disconnect or snapshot replacement
+        Stale --> [*]
+    }
+```
+
+The values themselves are stateless and immutable. Allocation, release,
+mapping and stale-state ownership belong to future registries/adapters.
+
+## Main sequence
+
+Identity construction and validation are synchronous. An external adapter reads
+its format, constructs the matching value, validates it, then publishes an
+explicit mapping or typed domain event. No value object performs I/O or retries.
+
+## Ownership, threading and resources
+
+- Values own only copied strings/integers and are caller-owned `RefCounted` references.
+- Public methods do not mutate values or shared state and are worker-safe.
+- Content/session/wire/server mapping records are owned by their future layer,
+  not by these values.
+- No Node, RID, file, socket, database, lock or cache resource is acquired.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Malformed ContentId | `is_valid()` | Invalid value remains inspectable | Source field/path supplied by parser | Regenerate or repair authored ID |
+| Invalid EntityId sequence | `is_valid()` | Registry must reject publication | Session/correlation context | Fix allocator/session mapping |
+| GUID word overflow | `has_valid_word_ranges()` | Codec must reject packet/replay value | Packet offset/opcode context | Reject malformed input; do not truncate |
+| Empty GUID | `is_empty()` | Preserved as protocol sentinel | Adapter decides whether field permits empty | Apply opcode/field-specific rule |
+| Missing server namespace/entry | `is_valid()` | Snapshot adapter rejects mapping | Backend/table/row context | Correct adapter schema mapping |
+| Unknown/stale mapping | Registry/snapshot lookup | No implicit numeric fallback | Typed IDs in diagnostic | Refresh snapshot/session or reject event |
+
+There is no cancellation inside constant-time value operations.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Identity contract version | 1 | All | No | Four separate namespaces and validation rules |
+| ContentId text form | Lowercase `8-4-4-4-12` UUID | Authoring/runtime/tools | No | Stable persisted key |
+| GUID decomposition | Opaque two-word storage | `wotlk_335a_build_12340` | No | Prevents unverified high-type assumptions |
+
+## Persistence, cache and migration
+
+- `ContentId.uuid_text` is the only stable persisted identity introduced here.
+- Containing schemas must store their own schema version and duplicate/reference policy.
+- `EntityId` must never be persisted across sessions.
+- `WowGuid` may appear in versioned packet replays as explicit high/low words or
+  the exact sixteen-digit hex form; a replay schema owns that choice.
+- `ServerEntryId` may appear in snapshots only with both namespace and entry.
+- This package is additive and migrates no existing data or cache.
+
+## Diagnostics and observability
+
+- Stable diagnostics use `ContentId.to_key`, `WowGuid.to_hex_string` and
+  `ServerEntryId.to_key`.
+- Runtime diagnostics may use `EntityId.to_debug_key` with a session correlation ID.
+- Production metrics/logging belong to registries and adapters; values emit none.
+
+## Verification
+
+- Contract test: `src/tools/verify_domain_identities.gd`.
+- Fixtures cover UUID normalization/malformed shape, positive/zero session IDs,
+  maximum/overflow GUID words, zero GUID and cross-table server entry collisions.
+- Dependency gate confirms no Node/Resource/Vector3 exposure.
+- Fidelity boundary: GUID bit meaning remains unclaimed until build-12340 packet fixtures.
+- Performance: constant-time integer checks and a bounded 36-character UUID scan.
+
+## Extension points
+
+- Content Project allocator and duplicate/reference validation.
+- Session-owned entity registry and explicit `WowGuid ↔ EntityId` mappings.
+- Backend capability adapters that define server entry namespaces.
+- Separate typed map/spell/item/quest/display/sound values.
+- Fixture-backed build-12340 GUID high-type decoding in the protocol layer.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Stable authored ContentId | Implemented contract | UUID normalization/validation fixtures | Allocator and schema arrive with Content Project |
+| Session-local EntityId | Implemented contract | Positive/zero/equality fixtures | Registry lifecycle arrives with gameplay world state |
+| Lossless opaque WowGuid | Implemented contract | Full unsigned words and hex fixture | Packet codec/high-type semantics need build-12340 fixtures |
+| Namespaced ServerEntryId | Implemented contract | Cross-table collision fixture | Backend namespace capability mapping arrives with server adapters |
+| Cross-namespace mappings | Planned | Architecture/ADR boundary | Implement only in owning registries/adapters |
+
+## Known gaps and risks
+
+- No allocator or duplicate registry exists yet.
+- GDScript `==` compares references; consumers must use domain `equals` methods
+  or canonical keys until a registry owns keying.
+- UUID shape validation deliberately does not enforce generation version/variant.
+- Server namespace vocabulary is adapter-owned and not yet centrally catalogued.
+- GUID high-type/object-kind semantics remain unverified rather than guessed.

+| Last verified | M02-GMP-INPUT-PROFILE-335-001 worktree, 2026-07-15 |
+| Profiles/capabilities | `RenderSandbox` debug movement; `Blizzlike335` selected bindings and keyboard turn with debug sprint/flight rejected |
+
+## Purpose
+
+Own current local velocity, acceleration and sandbox flight state independently
+of the player scene. Convert an immutable `MoveIntent` plus an explicit
+Godot-world movement basis into deterministic per-tick displacement and convert
+signed turn intent into a yaw delta without querying terrain, cameras, input
+devices or visual assets.
+
+## Non-goals
+
+- Apply world transforms or own a `CharacterBody3D`.
+- Query terrain height, collision, water or slopes.
+- Implement jump, fall, swim, server prediction or reconciliation.
+- Select the player basis versus camera-pivot basis; the scene adapter owns that decision.
+- Claim build-12340 movement fidelity from sandbox regression alone.

+
+## Ownership, threading and resources
+
+- The player scene creates and exclusively owns one movement controller.
+- The composition root creates one immutable capability value; the controller
+  retains it and exposes only its effective profile ID.
+- Velocity and flight state have the same lifetime as that controller.
+- All mutations currently occur on the main input/physics thread.
+- Read-only value returns are copies; consumers cannot mutate owned state.
+- No Nodes, Resources, RIDs, files, jobs or worker threads are created.
+- The supplied `Basis` is a Godot-world direction basis, not a typed world-position contract or coordinate conversion.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Negative physics delta | `advance` guard | Returns zero displacement; velocity unchanged | Unit regression | Resume with valid non-negative delta |
+| Missing scene basis owner | Scene composition defect | Controller cannot be called correctly | Scene/parser error or boundary test | Restore explicit scene dependency |
+| Flight toggle during motion | Command path | Velocity clears before next step | State-transition regression | Continue from zero velocity |
+| Flight/sprint request in `Blizzlike335` | Capability check | Request has no effect | Profile regression | Select explicit `RenderSandbox` only for tooling/debug scenes |
+| Unknown/null profile capability | Factory/constructor safe default | Uses `Blizzlike335`; debug movement disabled | Capability regression | Correct composition profile ID |
+| Missing terrain data | `TerrainGroundSample.is_available == false` | Scene skips existing ground snap | Stable terrain failure code | Replace/recover query backend |
+
+There is no asynchronous cancellation, retry or rollback. Recreating the
+controller resets velocity and flight state deterministically.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Forward speed | `7.0` units/s | Current sandbox | Fixed for controller lifetime | Target forward velocity |
+| Backward speed | `4.5` units/s | Current sandbox | Fixed for controller lifetime | Target backward velocity |
+| Strafe speed | `4.5` units/s | Current sandbox | Fixed for controller lifetime | Target lateral velocity |
+| Acceleration | `28.0` units/s² | Current sandbox | Fixed for controller lifetime | Acceleration and deceleration |
+| Flight vertical speed | `7.0` units/s | Sandbox debug | Fixed for controller lifetime | Vertical free-flight target |
+| Sprint multiplier | `6.0` | Sandbox debug | Fixed for controller lifetime | Multiplies planar and vertical targets |
+| Camera-relative basis | Selected only while flight is enabled | Sandbox debug | Per tick | Preserves existing pitched flight direction |
+| Debug sprint permission | Enabled | `RenderSandbox` only | Immutable | Allows sprint request multiplier |
+| Debug free-flight permission | Enabled | `RenderSandbox` only | Immutable | Allows toggle and vertical movement |
+| Compatibility-safe debug permissions | Disabled | `Blizzlike335` | Immutable | Ignores sprint/toggle requests |
+| Keyboard turn rate | `3.141594` rad/s | `Blizzlike335` composition | Fixed for controller lifetime | Server-contract default applied to signed turn intent |
+
+## Persistence, cache and migration
+
+Movement state is transient and not serialized. No schema, cache, migration or
+saved settings change is introduced. Future reconnect/replay state requires a
+separate versioned movement snapshot contract.
+
+## Diagnostics and observability
+
+- Logs: verifier emits `LOCAL_PLAYER_MOVEMENT PASS` or named invariant failures.
+- Metrics: none yet; update is constant-time vector math.
+- Debug views: current character facing and animation remain observable scene outputs.
+- Correlation IDs: not applicable to synchronous local sandbox state.
+
+## Verification
+
+- Unit/contract: `src/tools/verify_local_player_movement.gd` covers forward,
+  backward, strafe, rotated basis, acceleration, deceleration, sprint, flight,
+  pitched camera basis, state reset, signed keyboard turn and invalid delta.
+- Capability: `verify_player_movement_capabilities.gd` covers three profile-ID
+  cases, safe defaults, sprint/flight allow/reject behavior and two real scene compositions.
+- Boundary: verifier rejects Node/Input/Camera/ADT dependencies and movement
+  integration/state remaining in the player scene.
+- Scene integration: `verify_player_input.gd` drives the asset-free player
+  regression scene through forward motion and immediate flight toggle.
+- Fidelity evidence: translation defaults remain regression-locked against the
+  pre-extraction sandbox. The compatibility keyboard turn default is pinned to
+  TrinityCore 3.3.5 `playerBaseMoveSpeed[MOVE_TURN_RATE]`; that server contract
+  does not alone prove original-client timing parity.
+- Performance budget: constant-time vector math, no per-tick I/O or scene lookup;
+  `MoveIntent` allocation remains owned by the input package.
+
+## Extension points
+
+- Terrain/collision policy can consume displacement without changing input or velocity ownership.
+- A future server-aware predictor may replace this controller behind the scene composition boundary.
+- A typed movement snapshot may expose deterministic replay state when M08/M09 require it.
+- A future application profile can map to this narrow capability value without
+  coupling the movement controller to the application shell.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Scene-free local velocity state | Implemented | Pure controller and source boundary regression | Integrate target checklist after review |
+| Existing planar acceleration/speeds | Implemented | Exact numeric unit cases and real scene regression | Compare with build 12340 before fidelity claim |
+| Compatibility keyboard turn | Implemented | Pinned server-core value, signed pure cases and real-scene profile regression | Direct original-client timing comparison remains required |
+| Existing camera-relative free flight | Implemented in `RenderSandbox` | Pitched-basis, profile and toggle/reset cases | Original-client flight semantics remain out of scope |
+| Typed sprint/free-flight exclusion | Implemented | Pure and real-scene profile regressions | Application shell must select profile explicitly later |
+| Terrain height query | Implemented | Typed `TerrainQuery` and injected player regression | Ground-snap policy remains scene-owned |
+| Terrain collision movement policy | Planned | Height-only query does not model collision | Add slopes/holes/collision later |
+| Jump/fall/swim | Planned | M02/M09 roadmap | Requires terrain/liquid and server contracts |
+| Prediction/reconciliation | Planned | M08/M09 roadmap | Requires movement snapshot/network contract |
+
+## Known gaps and risks
+
+- Translation/acceleration defaults preserve the existing sandbox and are not original-client evidence.
+- Configuration is captured at scene `_ready`; runtime mutation of exported speed
+  properties does not reconfigure an existing controller.
+- Ground snap remains in the player scene, but its ADT data access is now behind
+  a replaceable `TerrainQuery`.
+- Runtime renderer scenes intentionally default to `RenderSandbox`; a future
+  game-client composition must explicitly select `Blizzlike335`.
+- `Blizzlike335` currently means only debug movement exclusion and must not be
+  interpreted as evidence that remaining movement semantics are 1:1.
+- The module uses Godot math value types; a future engine-independent gameplay
+  predictor may require scalar/domain movement contracts.

+
+## Lifecycle/state
+
+The planner is stateless. It has no initialization, reset, cancellation,
+recovery or shutdown work. Each call returns a complete detached value plan.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Loader as StreamingWorldLoader build loop
+    participant Planner as M2BuildBatchPlanner
+    participant Materializer as Animated/MultiMesh adapter
+    participant Scheduler as RenderBudgetScheduler
+    Loader->>Planner: plan_batch(count, offset, path kind, limits)

+    Loader->>Materializer: materialize selected transform slice
+    Loader->>Loader: adopt cursor/group completion
+    Loader->>Scheduler: consume M2_BUILD permit
+```
+
+## Ownership, threading and resources
+
+- The planner owns only call-local scalar values and the returned Dictionary.
+- The loader owns build-job Dictionaries, queue ordering, tile checks, resource
+  readiness/retry, serial numbers and group-index mutation.
+- Materializers own main-thread Node/MultiMesh construction under loader roots.
+- The scheduler owns the frame-local `M2_BUILD` counter.
+- Pure planning is thread-safe, though the current adapter calls it on main thread.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Zero/negative selected limit | Scalar clamp | Effective size becomes one | Contract fixture | Correct profile value later |
+| Empty transform group | Remaining count zero | Count zero; group completes | Contract fixture | Loader advances group |
+| Offset at/past end | Remaining count clamp | Count zero; offset resets | Contract fixture | Loader advances group |
+| Negative offset | No new validation | Historical arithmetic is preserved | Contract fixture | Loader inputs should remain valid |
+| Resource pending/missing | Outside planner | Loader rotates or advances as before | Existing cache/build diagnostics | Resource loader retry/fallback |
+| Tile cancelled | Outside planner | Loader cancels job before planning/materialization | Existing lifecycle gates | Eligible tile may requeue |
+
+## Configuration and capabilities
+
+The planner introduces no setting. It consumes existing
+`m2_animated_instances_per_tick` and `m2_multimesh_batch_size` values after the
+loader determines whether an animated prototype is available.
+
+## Persistence, cache and migration
+
+No persistence, schema or cache format participates. ADT/M2 cache versions,
+quality presets and rebuild instructions are unchanged.
+
+## Diagnostics and observability
+
+The planner emits no logs. Its verifier covers deterministic formula/source
+boundaries and records bounded 20,000-plan timing. Existing loader metrics retain
+queue depth, build activity and hitch observability.
+
+## Verification
+
+- `verify_m2_build_batch_planner.gd`: static/animated selection, invalid-limit
+  clamp, remaining cap, exact completion, empty/past-end and negative-offset
+  behavior, loader/dependency source boundaries and bounded timing.
+- Grouper, transform resolver, unique registry/dedupe, facade, internal-access,
+  manifest, shutdown, scheduler, streaming, coordinate, documentation and
+  coordination regressions remain required.
+- Fidelity evidence is formula extraction only. Asset-backed frame pacing and
+  visual output require the renderer checkpoint/performance workflow.
+
+## Extension points
+
+- A later package may define typed build-job state once queue/resource transitions
+  are extracted together with explicit cancellation and recovery.
+- Spatial-cell batching must use measured culling/performance evidence and must
+  not silently change this model-path batch cursor.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Static/animated batch cursor planning | Implemented extraction | Contract/source/timing verifier | Asset-backed p95/p99 pending |
+| Build queue/resource state machine | Remains in loader | Existing lifecycle regressions | Stateful extraction pending |
+| Spatial-cell batching | Planned | Renderer roadmap | Culling evidence/design pending |
+
+## Known gaps and risks
+
+- The result remains a Dictionary while loader build jobs are untyped Dictionaries.
+- Negative offsets are preserved rather than rejected to avoid a hidden behavior change.
+- Planning timing does not measure resource loading or materialization.
+- Private asset-backed p95/p99 and visual comparison remain unavailable.

+| Last verified | Worktree `work/sindo-main-codex/m03-m2-placement-grouper`, 2026-07-16 |
+| Profiles/capabilities | Existing static M2 worker-grouping path |
+
+## Purpose
+
+Convert valid raw ADT M2 placement records into ordered tile-local transforms
+grouped by the historically normalized relative model path.
+
+## Non-goals
+
+- Reserve cross-tile unique IDs or choose placement ownership.
+- Own WorkerThreadPool tasks, mutexes, result queues or tile lifecycle.
+- Load models, choose animated/static rendering or build MultiMesh batches.
+- Create Node, Mesh, material, Resource or RID objects.
+- Change path case, transform rules, batching or visual fidelity.

+WorkerThreadPool, mutexes, ResourceLoader, files, gameplay, network and editor UI
+are forbidden.
+
+## Public API

+```
+
+## Lifecycle/state
+
+The grouper retains no state. Every call constructs one stateless transform
+resolver and fresh output containers. Reset, cancellation and shutdown require
+no grouper action.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Loader as Loader worker callback
+    participant Grouper as M2PlacementGrouper
+    participant Resolver as M2PlacementTransformResolver
+    Loader->>Grouper: group_placements(origin, names, placements)
+    loop valid placement
+        Grouper->>Resolver: resolve basis and origin offset
+        Resolver-->>Grouper: value-only basis and offset
+        Grouper->>Grouper: append local Transform3D
+    end
+    Grouper-->>Loader: fresh path groups
+    Loader->>Loader: mutex-protected result enqueue
+```
+
+## Ownership, threading and resources
+
+- The grouper owns only call-local containers and transforms.
+- The loader owns tasks, mutex/result queue, tile/build state, caches, model
+  loading, Nodes, MultiMesh, Mesh, materials and RIDs.
+- Worker use is safe because the grouper and resolver mutate no shared state.
+- The caller owns returned containers; mutation cannot affect later calls.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Non-Dictionary placement | Type guard | Skip | Contract fixture | Repair parser input |
+| Invalid name ID | Bounds guard | Skip | Contract fixture | Repair name table/placement |
+| Empty path | Empty guard | Skip | Contract fixture | Supply valid MMDX entry |
+| Missing position/rotation/scale | Defaults | Zero position/rotation and scale 1 | Contract fixture | Expected fallback |
+| Zero/negative scale | Historical clamp | Basis scale uses `0.0001` | Contract fixture | Supply valid ADT scale |
+| Cancellation after grouping | Loader state check | Discard stale result | Loader regressions | Re-request eligible detail |
+
+Cancellation stays loader-owned because grouping has no task or partial state.
+
+## Configuration and capabilities
+
+No setting or profile branch is introduced. Preserved behavior includes
+backslash replacement without lowercasing, case-sensitive lowercase `.mdx/.mdl`
+conversion, first-seen ordering, tile-local subtraction and scale clamp `0.0001`.
+
+## Persistence, cache and migration
+
+No persistence or cache format participates. ADT and M2 cache versions are
+unchanged, so no rebuild or migration is required.
+
+## Diagnostics and observability
+
+The service emits no logs. Its verifier records contract results, source
+boundaries and bounded synthetic 100-by-256 placement timing. Loader metrics
+continue to own task/build/cache observability.
+
+## Verification
+
+- `verify_m2_placement_grouper.gd`: invalid input, path behavior, ordering,
+  defaults, local origin, regular/waterfall transforms, scale clamp, fresh output,
+  loader/source boundary and timing.
+- `verify_m2_placement_transform_resolver.gd`: three transform consumers remain
+  covered as two direct loader adapters plus the grouper adapter.
+- Registry/dedupe, facade, internal-access, manifest, shutdown, documentation and
+  coordination regressions remain required.
+- Fidelity evidence is exact extraction; no new asset-backed parity claim is made.
+
+## Extension points
+
+- `M2BuildBatchPlanner` now owns pure batch sizing/cursor progression; the
+  remaining build-job state machine stays behind explicit loader budgets.
+- Spatial cells require measured culling evidence and are outside this contract.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Pure path/transform grouping | Implemented extraction | Contract/source/timing verifier | Asset-backed traversal timing pending |
+| Worker/build orchestration | Remains in loader | Existing regressions | Separate stateful extraction required |
+| Spatial MultiMesh cells | Partial | Current path batches | Culling-driven design/evidence pending |
+
+## Known gaps and risks
+
+- Raw placement dictionaries remain the ADT parser boundary.
+- Uppercase extensions remain unchanged even though transform exception matching
+  is case-insensitive.
+- Grouping is by model path, not spatial culling cell.
+- Asset-backed p95/p99 and visual comparison remain unavailable.

+
+## Purpose
+
+Resolve the unscaled Godot-space orientation and optional local origin offset
+used by the pure placement grouper, placeholder rendering and instance creation.
+
+## Non-goals
+
+- Convert WoW/server/ADT coordinates or own placement positions.
+- Apply final scale clamps, build transforms, group placements or create Nodes.
+- Add, generalize or configure model-specific corrections.
+- Change M2 materials, animation, caches, visibility or quality profiles.
+- Claim general build-12340 placement parity.

+```
+
+## Lifecycle/state
+
+The resolver is stateless. It may be shared between the main thread and worker
+calls because each result is computed solely from value inputs. Construction,
+world reset and shutdown require no clear, cancellation or resource release.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Caller as Grouper or StreamingWorldLoader
+    participant Resolver as M2PlacementTransformResolver
+    participant Consumer as Grouper/placeholder/instance path
+    Caller->>Resolver: resolve_basis(rotation, path)
+    Resolver-->>Caller: unscaled Basis
+    Caller->>Resolver: resolve_origin_offset(rotation, path, scale)
+    Resolver-->>Caller: local offset
+    Caller->>Consumer: compose historical scaled Transform3D
+```
+
+## Ownership, threading and resources
+
+- The resolver retains no mutable state or engine resources.
+- The grouper owns worker-path final transforms; the loader owns placement records,
+  tasks, queues, caches and MultiMesh/Node/Mesh/material/RID creation and cleanup.
+- Pure methods are safe for grouper worker use and main-thread consumers.
+- Returned `Basis`/`Vector3` values have no lifetime coupling to the resolver.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty/unknown path | Allowlist miss | Regular Euler basis and zero offset | Contract fixture | Expected fallback |
+| Mixed case/backslashes/MDX | Normalization | Same calibrated model match | Contract fixture | None required |
+| Zero/negative scale for anchored offset | Numeric clamp | Use `0.0001` compensation scale | Contract fixture | Caller may supply valid ADT scale later |
+| World reset/shutdown | No retained state | No action | Existing shutdown verifier | New calls remain independent |
+
+There is no asynchronous operation or cancellation inside the resolver.
+
+## Configuration and capabilities
+
+The resolver introduces no settings. The preserved constants and allowlists are:
+
+- world yaw `PI` for `ElwynnCliffRock01/02`;
+- world yaw `PI/2` for `NewWaterfall` and `ElwynnTallWaterfall01`;
+- measured local axes/twist signs for both waterfall sheets;
+- measured tall-waterfall anchor `(-2.667799, 89.62273, 0.00129)`.
+
+## Persistence, cache and migration
+
+No persistence, schema or cache format participates. Existing ADT/M2 cache
+versions and rebuild instructions remain unchanged.
+
+## Diagnostics and observability
+
+The resolver emits no logs. The contract verifier compares formulas/constants,
+checks two direct loader consumers plus the grouper consumer and records bounded
+synthetic timing. Visual
+and asset-backed evidence remains in the renderer checkpoint workflow.
+
+## Verification
+
+- `verify_m2_placement_transform_resolver.gd`: regular fallback, path
+  normalization, both cliff rocks, both waterfalls, twist anchor, negative-scale
+  compensation, three consumers, source boundary and 10,000-pair timing.
+- M2 unique/dedupe, terrain, facade, internal-access, manifest, shutdown,
+  scheduler, streaming and coordinate regressions remain required.
+- Fidelity evidence is exact extraction of existing calibrated formulas. The
+  private asset/camera comparison that motivated them is not reproduced here.
+
+## Extension points
+
+- `M2PlacementGrouper` composes this resolver for the worker grouping path.
+- New model corrections require separate measured fidelity evidence; this module
+  is not a generic override registry.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Consistent transform rules across three M2 paths | Implemented | Formula/source/timing contract | Asset-backed visual recheck pending |
+| General ADT M2 placement parity | Partial | Existing checkpoint notes | Broader fixture coverage required |
+
+## Known gaps and risks
+
+- Four model-specific exceptions are empirical compatibility rules.
+- Most placements use raw Godot Euler behavior; independent client-wide
+  transform validation is incomplete.
+- Callers intentionally retain different final scale clamps.
+- Grouping, build, cache and render ownership remain in the streamer.

+
+## Ownership, threading and resources
+
+- The classifier owns only normalized-path boolean entries.
+- The loader owns raw loading, cache/resource selection, Mesh replacement and
+  material refresh metadata.
+- Raw Dictionaries are borrowed and never retained; only the computed boolean is cached.
+- Current calls and clears are serialized on the renderer main thread.
+- No Node, Resource, Mesh, material or RID reference crosses into the classifier.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Non-Dictionary batch/transform | Type guard | Skip entry or use identity defaults | Synthetic verifier | Correct parser data on next cleared lifetime |
+| Missing transforms/combos | Empty guard | No UV-driven rebuild | Synthetic verifier | Billboard classification still applies |
+| Invalid combo/transform index | Bounds guard | Skip stage | Synthetic verifier | Correct raw data and clear |
+| Repeated path with changed data | Cache hit | Preserve first decision | Memoization fixture | Map/reset clear recomputes |
+| Load/build failure | Outside classifier | Existing mesh fallback remains | Loader diagnostics | Existing reload/fallback path |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Maximum texture stages inspected | `4` | Existing M2 material path | No | Preserves historical four-stage shader boundary |
+| UV rotation-speed epsilon | `0.000001` exclusive | Existing M2 material path | No | Larger absolute speed requires rebuild |
+| `M2_MATERIAL_REFRESH_VERSION` | Loader constant `2` | All | Code version | Gates whether classifier is called |
+
+## Persistence, cache and migration
+
+Memoized booleans are runtime-only and are cleared at the two historical loader
+reset/shutdown sites. No persisted cache version or rebuild instruction changes.
+
+## Diagnostics and observability
+
+- Logs: none.
+- Metrics: `cached_path_count` is contract-level only and not added to runtime logs.
+- Debug views: detached path-to-boolean snapshot.
+- Correlation IDs: normalized M2 relative path.
+
+## Verification
+
+- `verify_m2_runtime_mesh_rebuild_classifier.gd`: billboard flag/count, invalid
+  variants, identity/non-identity rotation, positive/negative speed, exact
+  epsilon, four-stage cap, invalid indices, memoization, clear, source boundary
+  and 100-by-256 timing.
+- Existing M2 builder/material verifiers cover downstream shader/cache behavior.
+- Fidelity evidence is exact predicate/cache extraction. No new asset-backed or
+  original-client parity claim is made.
+- Performance budget: 25,600 classifications and clears under one second.
+
+## Extension points
+
+- A typed raw M2 material descriptor may replace the Dictionary only with parser
+  fixtures and a compatibility adapter.
+- Mesh request/cache/finalization state can be extracted separately without
+  changing this rebuild predicate.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Billboard rebuild classification | Implemented extraction | Flag/count fixtures | Asset-backed cache refresh timing pending |
+| UV-rotation rebuild classification | Implemented extraction | Combo/stage/threshold fixtures | More build-12340 material fixtures pending |
+| Runtime memoization lifetime | Implemented extraction | First-decision/clear/source fixtures | Byte/count runtime metric not exposed |
+| M2 mesh loading/finalization | Existing loader-owned | Material/shutdown regressions | Separate state extraction pending |
+
+## Known gaps and risks
+
+- Raw parser data remains Dictionary-based.
+- The first decision wins even if different raw data is passed for the same path;
+  this intentionally preserves prior cache behavior.
+- Only four texture stages are inspected, matching current material support.
+- No private asset traversal, descriptor-pressure, p95/p99 or paired visual run is included.

+
+## Purpose
+
+Ensure a positive ADT `MDDF.uniqueId` has at most one owning streamed tile while
+allowing unkeyed placements through and returning skipped keys for loader-driven
+candidate retry after the owner unloads.
+
+## Non-goals
+
+- Own tile state, retry queues, worker/group/build jobs or detail radius rules.
+- Group placements or create MultiMesh, Mesh, Node, material or RID resources.
+- Validate M2 paths, transforms, animation, materials or build-12340 fidelity.
+- Persist reservations or define a generic identity/ownership framework.
+- Change cache formats, quality profiles or placement visibility.

+
+## Ownership, threading and resources
+
+- The registry owns one private key-to-owner-string dictionary.
+- The loader owns tile-held owned/skipped arrays, retry discovery, task/build
+  lifecycle and every MultiMesh/Node/Mesh/material/RID side effect.
+- Calls currently occur on the renderer main thread. The registry has no lock and
+  must not be mutated concurrently.
+- Returned arrays and diagnostic dictionaries are fresh; source placement
+  dictionaries are passed through shallowly and must remain read-only.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Invalid placement variant | Type guard | Ignore entry | Contract test | Repair parser/adapter input |
+| Missing/non-positive ID | Key rule | Pass placement without ownership | Smoke/contract test | Expected legacy behavior |
+| Cross-tile duplicate | Owner lookup | Skip placement and return key once | Tile skipped-key state | Owner release triggers eligible candidate retry |
+| Non-owner release | Owner comparison | Ignore; preserve owner | Contract test | Release from recorded tile |
+| Reset/shutdown | Loader lifecycle | Clear all reservations | Shutdown regression/count | New world reserves afresh |
+
+There is no asynchronous work or cancellation inside the registry. Loader-owned
+tasks are cancelled independently before/reset around registry clearing.
+
+## Configuration and capabilities
+
+The registry introduces no settings. It applies to all positive IDs in the
+existing static M2 placement path. Detail radius, M2 enablement, build budgets
+and animation allowlists remain loader/profile configuration.
+
+## Persistence, cache and migration
+
+Reservations are runtime-only and are not serialized. M2 `.tscn/.glb`, animation,
+mesh/material refresh and ADT cache versions remain unchanged. No rebuild or
+migration is required.
+
+## Diagnostics and observability
+
+- `active_count()` continues to feed `m2_active_unique_ids` baseline metrics.
+- Detached diagnostics sort by unique key for deterministic inspection and expose
+  only strings/counts.
+- Contract timing covers repeated 256-placement reserve/release cycles. Asset-
+  backed streaming p95/p99 remains milestone acceptance work.
+
+## Verification
+
+- `verify_m2_unique_placement_registry.gd`: invalid/unkeyed handling, within-call
+  duplicate suppression, same-owner repeat, cross-tile skip, owner-checked release,
+  retry, idempotent clear, detached/sorted diagnostics, source boundary and timing.
+- `verify_m2_unique_dedupe.gd`: existing `uid:11785` cross-tile smoke now targets
+  the extracted public contract rather than loader-private methods.
+- Facade, terrain, internal-access, manifest, shutdown, scheduler, streaming and
+  coordinate regressions remain required.
+- Fidelity evidence is dedupe behavior preservation only. No new build-12340
+  visual parity claim is made.
+
+## Extension points
+
+- Expose detached ownership diagnostics through facade metrics only if needed.
+- Extract grouping/build orchestration as separate services with explicit budgets.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Cross-tile positive-ID ownership | Implemented extraction | Dedicated contract plus legacy smoke | Asset-backed boundary traversal timing pending |
+| Candidate retry and M2 build | Remains in loader | Existing release adapter/source boundary | Broader M2 service extraction required |
+
+## Known gaps and risks
+
+- Placement dictionaries are shallow pass-through values at the ADT boundary.
+- Same-owner reservations across separate calls intentionally pass again; the
+  caller's existing root/task guards prevent duplicate build requests.
+- First owner follows tile processing order, matching prior behavior rather than
+  a canonical geometric owner rule.
+- Group/build/load/animation caches and render finalization remain monolithic.

+
+## Purpose
+
+Convert remappable Godot Input Map actions into an immutable, scene-free
+`MoveIntent` that can be consumed by the independently testable local movement
+controller. Select either the preserved renderer-sandbox layout or the verified
+build-12340 movement bindings at the scene composition boundary.
+
+## Non-goals
+
+- Define authoritative server movement, prediction or reconciliation.
+- Own character transform, terrain queries, camera state or animation state.
+- Implement jump, autorun, left-button select/move or persisted binding settings.
+- Remove process-wide debug actions; Blizzlike335 sampling ignores them and the
+  movement capability boundary also rejects directly constructed debug requests.
+

+    Profile[PlayerMovementCapabilities] --> Movement
+    Movement --> Controller[ThirdPersonWowController adapter]
+    Controller --> Camera[ThirdPersonCameraRig]
+```
+
+Allowed dependencies:
+
+- `PlayerInputSource` may read Godot's process-wide `Input` adapter.
+- The scene controller may consume `MoveIntent` and camera-specific action names.
+- `MoveIntent` may contain scalar axes and request flags only.
+
+Forbidden dependencies:
+
+- `MoveIntent` must not read `Input`, inherit `Node`/`Resource`, or contain world coordinates.
+- The input source must not mutate player transforms, camera nodes or animation state.
+- Renderer, terrain parsers and network codecs must not read Input Map actions.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `MoveIntent` | Immutable value | Carries normalized forward, strafe, vertical and turn axes plus the sandbox sprint request | Created and consumed on the main physics tick; caller retains reference | Constructor clamps axes; no I/O failure |

+| `PlayerInputActions` | Constants | Provides stable action names shared by configuration and adapters | Process lifetime | Missing project actions are detected by verification |
+| `PlayerInputSource.new(profile_id)` | Constructor | Selects sandbox or compatibility action layout once | Scene lifetime | Unknown IDs fail closed to `Blizzlike335` |
+| `PlayerInputSource.sample_move_intent()` | Adapter method | Samples the selected action layout for one physics tick | Main thread; returned intent is independent of adapter lifetime | Missing actions resolve to zero strength and are a configuration defect |
+| `PlayerInputSource.compose_move_intent(...)` | Pure factory | Clamps strengths, cancels opposites and normalizes diagonal planar input | Any thread with scalar inputs | None |
+| `PlayerInputSource.compose_blizzlike_335_move_intent(...)` | Pure factory | Composes Q/E strafe, A/D turn and right-mouse A/D strafe semantics | Any thread with scalar inputs | None |

+| Input | Mouse action events | Godot `_unhandled_input` dispatch | `ThirdPersonCameraRig` through player dispatch | Engine-owned event | Current input dispatch only |
+| Output | `MoveIntent` | `PlayerInputSource` | `LocalPlayerMovementController` through scene composition | Immutable caller-held value | One physics tick |
+| Output | Debug sprint request/vertical axes | `PlayerInputSource` | Capability-gated movement controller | Immutable intent fields | One physics tick |
+| Output | Signed turn axis | `PlayerInputSource` | `LocalPlayerMovementController` | Immutable scalar | One physics tick |
+| Output | Camera action names | `PlayerInputActions` | `ThirdPersonCameraRig` | Static constants | Process lifetime |
+
+Side effects:
+
+- `PlayerInputSource` has no side effects beyond reading current engine input.
+- `ThirdPersonCameraRig` owns mouse mode, orbit state and camera transforms;
+  player remains only the event-dispatch composition boundary.
+- No filesystem, cache, network, database or renderer-resource mutation occurs.

+
+## Lifecycle/state
+
+The adapter is stateless. The scene composition root creates one
+`PlayerInputSource` and `LocalPlayerMovementController` in `_ready`; each physics
+tick produces a new immutable intent. Flight enabled/disabled state is owned by
+the movement controller and is not hidden in the input adapter. RenderSandbox
+retains debug requests in its intent; Blizzlike335 does not sample them, and the
+immutable movement capability also rejects directly constructed requests.

+    Player->>Move: calculate yaw delta, then advance(intent, selected basis, delta)
+    Move-->>Player: displacement and velocity state
+```
+
+## Ownership, threading and resources
+
+- The controller owns the input-source reference for its scene lifetime.
+- Each `MoveIntent` is immutable and retained only by its consumer.
+- Sampling and controller mutation occur on the main physics thread.
+- The module creates no Nodes, Resources, RIDs, workers or background jobs.
+- Input Map definitions are project configuration; runtime remapping remains
+  engine-owned and does not mutate the domain value.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Required action missing | Headless contract verifier | Godot returns zero input for that action | `PLAYER_INPUT` failure naming action | Restore action or user mapping |
+| Conflicting opposite actions | Pure composition | Strengths cancel deterministically | Covered by contract test | Release/remap one action |
+| Strength outside range | Pure composition | Value clamps to `[0, 1]` before axis calculation | Covered by contract test | Input adapter may be corrected independently |
+| Controller disabled/unloaded | Scene lifecycle | Sampling stops with physics processing | Existing scene lifecycle | Re-enable or recreate scene |
+| Debug request in `Blizzlike335` | Input profile and movement capability checks | Input adapter omits it; directly constructed request has no effect | Profile/capability regressions | Use `RenderSandbox` only when debug movement is intended |
+
+There is no asynchronous operation to cancel and no persisted state to roll back.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Forward/backward | Physical W/S and Up/Down | Both | Yes, through Input Map | Produces signed forward axis |
+| Strafe left/right | Physical A/D | `RenderSandbox` | Yes | Preserves renderer baseline |
+| Strafe left/right | Physical Q/E | `Blizzlike335` | Yes | Matches selected build-12340 defaults |
+| Keyboard turn | Physical A/D and Left/Right | `Blizzlike335` | Yes | Produces signed turn axis |
+| Camera-held A/D | Physical A/D while right mouse is held | `Blizzlike335` | Yes | Produces strafe and suppresses keyboard turn |
+| Camera rotate | Right mouse button | Current render sandbox | Yes | Captures/releases mouse for orbit |
+| Camera zoom | Mouse wheel | Current render sandbox | Yes | Adjusts current camera distance |
+| Debug sprint | Shift | Executable only in `RenderSandbox` | Yes | Requests multiplier; `Blizzlike335` ignores it |
+| Debug flight up/down/toggle | E/Q/Space | Executable only in `RenderSandbox` | Yes | Requests free flight; `Blizzlike335` remains grounded |
+
+## Persistence, cache and migration
+
+The action names are additive project configuration. No saved binding schema,
+cache or migration exists yet. Renaming an action is a contract change and must
+provide a settings migration once user settings are persisted.
+
+## Diagnostics and observability
+
+- Logs: dedicated verifier emits `PLAYER_INPUT PASS` or one failure per invariant.
+- Metrics: none; sampling cost is one small value allocation per physics tick.
+- Debug views: none.
+- Correlation IDs: not applicable to local synchronous input.
+
+## Verification
+
+- Unit/contract tests: `src/tools/verify_player_input.gd` validates all actions,
+  both profile defaults, axis cancellation/clamping/normalization, turn routing,
+  safe profile fallback, fixture provenance and debug request flags.
+- Integration/E2E: `src/tests/scenes/player_input_regression.tscn` is loaded by
+  the verifier, which drives sandbox forward/camera/flight plus compatibility
+  keyboard turn and right-mouse strafe through real scene controllers.
+- Profile integration: `verify_player_movement_capabilities.gd` drives sprint
+  and flight actions through real `RenderSandbox` and `Blizzlike335` scene instances.
+- Fidelity evidence: sanitized fixture `player_input_profile_335.json` pins the

+  movement/camera commands. TrinityCore 3.3.5 revision
+  `2853a621d6af91a803787a2b8a509f4ce3e0300d` pins the server-contract player
+  turn rate. WoWee revision `626243e937fb93965fa583a6507ed5a1aa7dda4b`
+  supports right-mouse A/D strafe routing. Both are compatibility references,
+  not direct original-client timing/conditional-behavior proof.
+- Performance budgets: no I/O, jobs or scene lookup per sample; one immutable
+  intent allocation per physics tick.
+- Manual diagnostics: run the Eastern Kingdoms scene and remap one movement
+  action in Project Settings before checking movement.
+
+## Extension points
+
+- A gamepad/accessibility adapter may call `compose_move_intent` without changing
+  movement consumers.
+- A later input-context owner may suppress gameplay actions while preserving the
+  same intent contract.
+- A future server-aware movement predictor may replace the current local
+  movement consumer without changing `PlayerInputSource`.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Remappable current sandbox controls | Implemented | `verify_player_input.gd` action/default checks | Add persisted user binding settings later |
+| `PlayerInputSource → MoveIntent` seam | Implemented | Pure composition and controller boundary checks | Local movement consumer is now extracted |
+| Selected 3.3.5a movement defaults | Implemented | Pinned private-source hashes, sanitized selected bindings and profile regressions | Jump, autorun and left-button behavior remain planned |
+| Compatibility-profile exclusion of sprint/flight | Implemented | Typed capability and two real-scene regressions | Application shell selection remains future work |
+| Jump/fall/swim/fly gameplay semantics | Planned | M02 target and gameplay roadmap | Implement after terrain/movement state extraction |
+
+## Known gaps and risks
+
+- Only selected movement/camera binding facts are implemented; the fixture explicitly records unimplemented defaults.
+- Input Map still exposes debug bindings process-wide; the movement consumer now
+  rejects their effects outside `RenderSandbox`.
+- Camera state is extracted; active collision remains an explicit planned policy.
+- There is no persisted user keybinding format or UI yet.

+## Metadata

+| Profiles/capabilities | Runtime and Editor main-thread operation quotas; profile values supplied by streamer composition |
+
+## Purpose
+
+Issue a bounded number of permits for each renderer operation lane during one
+process frame. The scheduler centralizes quota accounting and teardown
+cancellation without taking ownership of queues or render work.
+
+## Non-goals
+
+- Own, sort, drain or cap the stored length of a renderer queue.
+- Submit, cancel or await worker and `ResourceLoader` tasks.
+- Execute callbacks or mutate the SceneTree, resources, caches or RIDs.
+- Adapt limits from elapsed time or create a general job/dependency framework.
+- Select renderer quality or compatibility profiles.

+Cancellation is intentionally terminal. A new renderer scene creates a new

+```
+
+## Ownership, threading and resources
+
+- `StreamingWorldLoader` owns every queue, task registry, cache, Node, Resource and RID.
+- The scheduler owns two small per-frame counter dictionaries and one terminal flag.
+- The streamer preserves operation order. In particular, chunk removals and
+  creations share `CHUNK_GEOMETRY`, with removals drained first.
+- All current scheduler calls occur on the Godot main thread. The service has no
+  mutex and is not safe for concurrent mutation.
+- A scheduler instance lives exactly as long as its loader instance.
+
+## Errors, cancellation and recovery
+
+| Condition | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Negative/zero limit | `begin_frame` clamp | Lane issues no permits | Contract verifier | Correct configuration or accept disabled lane |
+| Unknown lane | Permit lookup miss | Returns `false`/zero | Contract verifier | Add the lane to the frame snapshot |
+| Exhausted lane | Remaining count is zero | Work remains in caller queue for a later frame | Queue-depth/hitch metrics | Next `begin_frame` replenishes permits |
+| Renderer teardown | Streamer calls `cancel` before task waits | New permits stop immediately | Shutdown ownership regression | New scene creates a new scheduler |
+| In-flight operation at cancel | Caller already consumed permit | Scheduler does not interrupt it | Ownership docs | Caller completes/cleans it through existing shutdown path |
+
+This cancellation scope is permit issuance, not worker cancellation. Existing
+task/result staleness and shutdown waits remain streamer responsibilities.
+
+## Configuration and capabilities
+
+The streamer's existing exported values populate 16 lanes: tile finalization,
+terrain upgrade/control-splat/splat-cache/splat-build, water finalization, shared
+chunk geometry, tile-load starts, tile LOD create/remove, M2 animation/mesh
+finalization and build, WMO instance/group build, and detail synchronization.
+Defaults and quality-preset assignments are unchanged. `tile_finalize` retains
+its historical minimum of one; other negative values behave as zero.
+
+## Persistence, cache and migration
+
+The module is runtime-only and serializes nothing. It changes no cache, asset,
+scene, protocol or database format and requires no version bump or migration.
+
+## Diagnostics and observability
+
+- `consumed_permits_snapshot` exposes detached per-frame counts for tests and
+  future facade metrics without exposing mutable scheduler state.
+- Existing queue depths, named hitch sections and `HITCH`/`PERF` logs remain in
+  `StreamingWorldLoader`.
+- No scheduler logging occurs on the hot permit path.
+
+## Verification
+
+- `src/tools/verify_render_budget_scheduler.gd` covers exact exhaustion,
+  independent lanes, shared removal/create priority, frame reset, invalid/unknown
+  lanes, detached diagnostics, terminal cancellation and source boundaries.
+- The verifier performs 20,000 permit checks with a generous 150 ms regression
+  ceiling on the headless runner; this is a guard, not a renderer p95 claim.
+- Integration regressions must retain the seven renderer checkpoint plans and
+  existing focus/planner/facade contracts.
+- Fidelity evidence is behavior-preserving: exported values, process order,
+  cache versions and visual operations are unchanged. No build-12340 parity
+  claim follows from this extraction.
+
+## Extension points
+
+- Add facade consumption metrics using detached snapshots.
+- Move a service's queue drain behind its own boundary while retaining these lane IDs.
+- Add measured time-aware policy only after asset-backed p95/p99 evidence proves
+  fixed operation counts insufficient; do not embed callbacks in this scheduler.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Per-lane frame bounds | Implemented | Exact exhaustion and independent-lane contracts | Asset-backed p95/p99 baseline remains |
+| Shared removal/create priority | Implemented | Synthetic shared `CHUNK_GEOMETRY` contract | Other service priorities remain streamer-owned |
+| Teardown permit cancellation | Implemented | Terminal cancellation contract and loader source gate | Worker stale-result cancellation remains streamer-owned |
+| Detached consumption diagnostics | Implemented | Snapshot isolation contract | Not yet exposed through facade metrics |
+
+## Known gaps and risks
+
+- Queue storage length is not capped; only per-frame draining is bounded.
+- Worker concurrency and stale-result cancellation remain existing streamer logic.
+- Exact p95/p99 impact requires local extracted assets and paired baseline runs.
+- Lane IDs are dynamic dictionary keys; the verifier guards the current contract.

+
+## Purpose
+
+Calculate which available ADT tiles are wanted and retained for one typed focus

+
+## Lifecycle/state
+
+The planner is stateless. A call creates local center/set dictionaries, freezes
+the result dictionaries in `StreamingTargetPlan`, returns the plan and retains
+no reference to inputs or output. There is no retry, cancellation or shutdown
+state machine.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Stream as StreamingWorldLoader
+    participant Planner as StreamingTargetPlanner
+    participant Mapper as CoordinateMapper

+    Planner->>Plan: freeze focus/wanted/retained result
+    Plan-->>Stream: immutable target plan
+    Stream->>Stream: apply queues, LOD and detail state
+```
+
+## Ownership, threading and resources
+
+- `StreamingWorldLoader` owns the available catalog and must not mutate it during a planning call.
+- `StreamingTargetPolicy` and typed focus remain caller-owned immutable values.
+- The planner owns temporary center/set values only until plan construction.
+- `StreamingTargetPlan` owns its read-only result dictionaries.
+- The planner creates no Node, Resource, RID, thread, mutex or task.
+- Current runtime calls occur on the main thread; scene-free contracts permit a
+  future worker call only after catalog publication/ownership is explicit.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty/unavailable catalog | No membership matches | Valid plan with empty sets | Streamer retains existing missing-data diagnostics | Load a valid WDT/directory catalog and replan |
+| Focus outside catalog/grid | Typed coordinate does not match keys | Valid focus tile with filtered empty/partial sets | Caller diagnostic if required | Supply valid focus/map or catalog |
+| Negative prewarm/retain margin | Policy effective-radius query | Margin clamps to zero | Contract test | Correct configuration if negative value was unintended |
+| Boundary threshold outside range | Policy query | Clamp to `0.0..0.49` | Contract test | Correct configuration or accept safe clamp |
+| Plan no longer current | New focus/config/catalog revision | Caller discards ephemeral plan | Streamer refresh diagnostics | Replan from current inputs |
+
+Cancellation is not applicable: planning is synchronous, bounded and owns no
+external work. A returned stale plan is simply not retained by the planner.
+
+## Configuration and capabilities
+
+| Setting/capability | Default source | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| `lod2_radius_chunks` | Streamer scene/profile | Renderer | Yes at composition/debug boundary | Converts chunk coverage to minimum ADT radius |
+| `lod2_tile_radius` | Streamer scene/profile | Renderer | Yes | Minimum visible ADT radius |
+| `warm_tile_margin` | Streamer scene/profile | Renderer | Yes | Extends chunk-derived visible radius |
+| `prewarm_tile_margin` | Streamer scene/profile | Renderer | Yes | Extends wanted/load radius |
+| `retain_tile_margin` | Streamer scene/profile | Renderer | Yes | Extends retained hysteresis radius |
+| `boundary_prefetch_threshold` | Streamer scene/profile | Renderer | Yes | Adds adjacent/corner prefetch centers near tile boundaries |
+| Editor preview radius | Editor scene | Authoring preview | Yes | Square wanted/retained preview set |
+
+The planner does not select `Blizzlike335` or `Enhanced`; it applies the values
+already selected by renderer composition.
+
+## Persistence, cache and migration
+
+- Planner contracts are runtime-only and are not serialized.
+- Existing tile keys and cache paths are unchanged.
+- No cache/resource/schema version bump or migration is required.
+
+## Diagnostics and observability
+
+- Logs remain emitted by `StreamingWorldLoader` after applying a plan.
+- `StreamingTargetPlan` exposes focus/wanted/retained data for deterministic tests.
+- Dedicated verifier reports case count, iteration count, total time and average plan time.
+- No correlation ID is required for synchronous ephemeral plans.
+
+## Verification
+
+- Unit/contract: `src/tools/verify_streaming_target_planner.gd` covers center
+  radii, edge/corner cross product, catalog filtering, clamps, editor behavior,
+  input/result ownership and scene-free dependencies.
+- Integration: streamer source gate confirms both runtime/editor delegation and
+  removal of `_predictive_focus_tiles` from the monolith.
+- Fidelity evidence: expected sets encode the pre-extraction formulas; renderer
+  checkpoint dry-run must retain all seven checkpoint plans.
+- Performance budget: 250 synthetic High-like corner plans average at most
+  `4.0 ms` each on the headless regression runner; measured result is recorded
+  in test output.
+- Manual diagnostics: unchanged `StreamingWorld` focus/wanted/queued log.
+
+## Extension points
+
+- Direction/velocity/frustum priority can extend policy/input only with fixtures
+  and a compatibility-safe default reproducing the current position-only plan.
+- Multi-focus planning may union additional typed centers without giving the
+  planner ownership of queues or consumers.
+- Queue ordering remains a separate scheduler/application responsibility.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Runtime wanted/retained sets | Implemented | Center/corner/catalog fixtures | Add paired traversal performance evidence |
+| Boundary prefetch centers | Implemented | Edge/corner cross-product fixture | Direction/velocity prediction not implemented |
+| Editor preview set | Implemented | Negative/radius-one fixtures | Editor viewport integration remains existing adapter |
+| Scene-free deterministic execution | Implemented | Dependency/source gate and 250-iteration run | Worker execution is unnecessary today |
+| Queue priority/LOD | Not in module | Preserved in streamer | Separate extraction packages |
+
+## Known gaps and risks
+
+- Tile-key sets preserve the streamer's internal string representation; a typed
+  catalog migration is deferred until it can remove, rather than duplicate, that source of truth.
+- Planner time scales with the union of square radii/prefetch centers. The
+  current bounded regression covers High-like corner input but not pathological custom radii.
+- Exact p95/p99 frame impact still requires renderer baseline runs with local assets.
+- Direction, velocity and camera frustum do not influence target selection yet.

+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `TerrainChunkGeometryQueuePlanner.plan(tile_states, focus_position)` | Pure query | Return fresh `create_requests` and `remove_requests` arrays | Synchronous; caller owns result | Null/wrong focus returns two empty arrays |
+
+Script-identity validation uses a preload and therefore works from a cold Godot
+global-class cache.
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Tile-state read model with current chunks and desired LODs | Streamer | Planner | Loader-owned; read only | One rebuild |
+| Input | Desired tile LOD | Tile LOD calculation | Planner | Scalar in loader state | One rebuild |
+| Input | Parsed chunk origins and tile fallback origin | ADT result/loader | Planner | Loader-owned; read only | Map session |
+| Input | `GodotWorldPosition` | Streamer focus adapter | Planner | Immutable caller reference | One rebuild |
+| Output | Remove `{tile, chunk}` records | Planner | Loader removal queue | Fresh caller array/dictionaries | Until drained/rebuilt |
+| Output | Create `{tile, chunk, lod, dist_sq}` records | Planner | Loader creation queue | Fresh nearest-first array/dictionaries | Until drained/rebuilt |
+
+Distance is horizontal XZ squared distance from the chunk origin, not its center.
+Y is intentionally ignored. A missing/sparse parsed origin falls back to the
+tile state's existing origin exactly as before extraction.

+## Data flow
+
+```mermaid

+```
+
+## Lifecycle/state
+
+The planner is stateless. Each loader queue rebuild supplies current read models
+and receives new arrays. The loader adopts and drains those arrays until another
+rebuild replaces them. Planner destruction requires no cleanup or cancellation.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Loader as StreamingWorldLoader
+    participant Planner as TerrainChunkGeometryQueuePlanner
+    participant Budget as RenderBudgetScheduler

+
+## Ownership, threading and resources
+
+- The planner owns only call-local arrays and dictionaries until return.
+- The loader owns adopted queue storage, drain ordering, tile/chunk state and all
+  Mesh/Node/material/RID side effects.
+- Calls and drains currently run on the renderer main thread. The planner has no
+  lock, task, retained resource or concurrent mutation.
+- Removal and creation continue to share the existing `chunk_geometry` budget lane.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null/wrong focus script | Identity guard | Return empty request arrays | Contract verifier | Supply typed focus and rebuild |
+| Sparse/out-of-range chunk data | Origin resolver | Use tile fallback origin | Synthetic fixture | Normal ADT completion restores precise origin |
+| Tile LOD becomes desired | Desired tile LOD check | Remove every current chunk; no chunk creates | Queue metrics | Existing tile-LOD create path takes over |
+| Queue rebuild before drain | Loader lifecycle | Replace old desired-operation arrays | Existing queue metrics | Latest state wins |
+| Shutdown/map reset | Loader lifecycle | Loader clears queues; planner has nothing to cancel | Shutdown verifier | New session replans |
+
+## Configuration and capabilities
+
+The planner introduces no settings. It consumes already-calculated desired LOD
+state. Operation limits, profile defaults and removal-first drain order remain
+loader/scheduler configuration.
+
+## Persistence, cache and migration
+
+No serialization, cache entry or format changes. Baked terrain, control-splat
+and splat caches require no rebuild or migration.
+
+## Diagnostics and observability
+
+The planner emits no logs. Existing queue metrics observe the adopted arrays.
+The contract verifier reports semantic cases and bounded multi-tile timing.
+Asset-backed p95/p99 remains milestone acceptance work.
+
+## Verification
+
+- `verify_terrain_chunk_geometry_queue_planner.gd`: missing/mismatched/unchanged
+  chunks, tile-LOD removal, sparse origin fallback, XZ-only distance, stable
+  removals, nearest creates, invalid focus, loader boundary and bounded timing.
+- Existing LOD planner, terrain cache, facade, internal-access, manifest,
+  shutdown, scheduler, streaming and coordinate regressions remain required.
+- Fidelity evidence is exact branch/request/order preservation only. No new
+  build-12340 visual parity claim is made.
+
+## Extension points
+
+- Extract tile-LOD operation planning as its own bounded contract if justified.
+- Add explicit typed tile-state adapters only when more than one consumer exists.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Pure chunk create/remove planning | Implemented extraction | Asset-free semantic/source/timing verifier | Asset-backed p95/p99 pending |
+| Queue execution/resource ownership | Remains in loader | Drain source boundary and scheduler regression | Further terrain decomposition required |
+
+## Known gaps and risks
+
+- Raw tile/chunk dictionaries remain a transitional ADT adapter boundary.
+- The planner performs a second linear tile-state pass beside tile-LOD planning;
+  bounded synthetic timing is green, but asset-backed frame metrics are pending.
+- Equal-distance create ordering retains comparator behavior without a tie-breaker.
+- Terrain geometry finalization and state mutation remain monolithic.

+# Terrain Chunk LOD Planner
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented extraction |
+| Target/work package | M03 / `M03-RND-TERRAIN-LOD-PLANNER-001` |
+| Owners | Pure desired chunk-LOD calculation only |
+| Last verified | Worktree `work/sindo-main-codex/m03-terrain-chunk-lod-planner`, 2026-07-16 |
+| Profiles/capabilities | Existing Performance/Balanced/High/Custom radii |
+
+## Purpose
+
+Calculate the desired terrain LOD for each populated parsed ADT chunk from one
+typed Godot-space focus and one immutable renderer-policy snapshot.
+
+## Non-goals
+
+- Own tile/chunk state, queues, budgets, tasks, Mesh, Node, material or RID.
+- Select tile LOD, create/remove geometry or apply a completed plan.
+- Normalize custom radii, change profile defaults or claim visual parity.
+- Parse ADT data or convert between WoW and Godot coordinate spaces.
+
+## Context and boundaries
+
+```mermaid
+flowchart LR
+    Focus[GodotWorldPosition] --> Planner[TerrainChunkLodPlanner]
+    Chunks[Parsed ADT chunk records] --> Planner
+    Config[Streamer LOD configuration] --> Policy[TerrainChunkLodPolicy]
+    Policy --> Planner
+    Planner --> Desired[chunk index to LOD 0/1/2]
+    Desired --> Loader[StreamingWorldLoader state adapter]
+    Loader --> Queue[Existing create/remove queues and budgets]
+```
+
+Allowed dependencies are the typed Godot position, immutable policy and
+call-local Array/Dictionary/Vector3 values. SceneTree, RenderingServer, gameplay,
+network, files, tasks and persistent caches are forbidden.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `TerrainChunkLodPolicy.new(...)` | Immutable value | Snapshot enabled flag, three raw radii and chunk size | Caller-owned; one planning refresh | Values are preserved without normalization |
+| `TerrainChunkLodPlanner.plan(chunks, focus_position, policy)` | Pure query | Map populated source indices to LOD 0/1/2 | Synchronous; result caller-owned | Invalid/null typed inputs or disabled policy return empty |
+
+The planner validates scripts by preloaded identity so it works from a cold
+Godot global-class cache.
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Parsed chunk array with `origin: Vector3` | ADT load result | Planner | Loader-owned; read only | One call |
+| Input | `GodotWorldPosition` | Streamer focus adapter | Planner | Immutable caller reference | One call |
+| Input | `TerrainChunkLodPolicy` | Streamer exported configuration | Planner | Immutable caller reference | One call |
+| Output | `{source_chunk_index: 0/1/2}` | Planner | Loader desired state | Fresh caller dictionary | One call |
+
+The Y coordinate is intentionally ignored. Empty chunk records and chunks beyond
+the third radius are absent from the result.
+
+## Data flow
+
+```mermaid
+flowchart TD
+    Start[plan] --> Valid{Typed inputs and enabled?}
+    Valid -->|no| Empty[Return empty dictionary]
+    Valid -->|yes| Radii[Square raw radius times chunk size]
+    Radii --> Iterate[Visit source chunk indices in order]
+    Iterate --> Populated{Record populated?}
+    Populated -->|no| Iterate

+    Threshold -->|LOD0/1/2| Record[Record source index]
+    Threshold -->|outside| Iterate
+    Record --> Iterate
+    Iterate --> Done[Return desired mapping]
+```
+
+## Lifecycle/state
+
+The planner is stateless. A policy is constructed for one refresh, read during
+synchronous planning and released. The returned dictionary is then owned by the
+loader state. There is no cancellation, recovery state or retained resource.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Stream as StreamingWorldLoader
+    participant Policy as TerrainChunkLodPolicy
+    participant Planner as TerrainChunkLodPlanner
+    Stream->>Policy: snapshot enabled/radii/chunk size
+    Stream->>Planner: plan(chunks, typed focus, policy)
+    Planner-->>Stream: fresh desired LOD dictionary
+    Stream->>Stream: existing tile state, queue and budget application
+```
+
+## Ownership, threading and resources
+
+- Planner and policy own no engine resources, nodes, RIDs, tasks or caches.
+- The loader retains parsed chunks, desired state and every application side effect.
+- Current calls run synchronously on the renderer main thread; the pure inputs
+  also make isolated contract testing possible without a world scene.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null/wrong focus or policy script | Identity guard | Empty plan | Contract verifier | Supply typed values next refresh |
+| Disabled chunk LOD | Policy flag | Empty plan; existing tile-LOD fallback applies | Existing renderer state | Enable profile option |
+| Empty chunk record | Record guard | Preserve sparse source index; omit record | None | Not an error |
+| Custom negative radius | No normalization | Existing squared-radius behavior is retained | Regression fixture | Change caller configuration if undesired |
+
+There is no asynchronous work or cancellation token.
+
+## Configuration and capabilities
+
+The policy snapshots `use_chunk_terrain_lods`, `lod0_radius_chunks`,
+`lod1_radius_chunks`, `lod2_radius_chunks` and the existing `CHUNK_SIZE`. Inclusive
+squared thresholds and raw custom values deliberately preserve prior behavior.
+
+## Persistence, cache and migration
+
+No serialization or cache format changes. Existing baked terrain, control-splat
+and splat cache versions remain unchanged and require no rebuild.
+
+## Diagnostics and observability
+
+The service emits no logs. The contract verifier reports semantic cases and a
+bounded synthetic timing. Asset-backed p95/p99 remains milestone acceptance work.
+
+## Verification
+
+- `verify_terrain_chunk_lod_planner.gd`: center and vertical invariance,
+  inclusive thresholds, sparse/outside chunks, disabled/custom-negative policy,
+  loader delegation and 250-by-256 bounded planning.
+- Renderer cache, facade, internal-access, baseline, scheduler, target-planner,
+  focus, ground-query and coordinate-boundary regressions remain required.
+- Fidelity evidence is formula preservation only; no new build-12340 visual
+  equivalence claim is made.
+
+## Extension points
+
+- Add measured direction/velocity only through an explicit policy/contract change.
+- Keep queue prioritization and LOD application as separately bounded services.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Pure chunk desired-LOD calculation | Implemented extraction | Asset-free semantic/source-boundary contract | Asset-backed p95/p99 pending |
+| Queue/state/finalization ownership | Remains in loader | Source-boundary regression | Further terrain decomposition required |
+
+## Known gaps and risks
+
+- Raw negative and non-monotonic custom radii retain historical squared/ordered
+  semantics, even though such settings may be surprising.
+- The planner is linear in parsed chunk count and allocates one result dictionary.
+- Terrain build, quality upgrades and geometry lifecycle remain monolithic.

+| Last verified | Worktree `work/sindo-main-codex/m03-terrain-quality-cache`, 2026-07-16 |
+| Profiles/capabilities | Performance/Balanced/High/Custom capacity; session-memory only |
+
+## Purpose
+
+Retain eligible full-quality terrain Mesh references after ADT tile state unload,
+so a revisit can restore quality without flashing to a lower-quality fallback,
+while bounding retained references with the existing least-recently-used policy.
+
+## Non-goals
+
+- Parse/build terrain, own tile state or schedule quality-upgrade tasks.
+- Create/finalize Nodes or RIDs, mutate materials or choose terrain LOD.
+- Persist cache entries or change baked/control-splat/splat format versions.
+- Cache control-splat/splat sources whose active radius has separate ownership.
+- Provide a generic cache framework or change profile capacity defaults.

+
+Allowed dependencies: `Mesh`, Dictionary/Array scalar containers and the loader

+```
+
+## Ownership, threading and resources
+
+- The cache owns its dictionary, ordered tile keys and retained Mesh references.
+- The loader retains tile state, async tasks/results, quality selection and all
+  Node/RID/material finalization.
+- Returned records are new dictionaries; their Mesh is a shared reference.
+- Calls currently occur on the main renderer thread. The service has no lock and
+  must not be mutated concurrently.
+- `clear` deterministically drops references during the existing world reset path.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty key/null Mesh | Store guard | Reject unchanged | Boolean/test | Fix caller result |
+| Splat/control source | Admission list | Reject unchanged | Boolean/test | Keep source in active-radius ownership |
+| Zero/negative capacity | Clamp and trim | Entry immediately evicted; cache empty | Snapshot/count | Increase profile capacity |
+| Miss/invalid entry | Restore validation | Remove invalid and return empty | Empty record | Existing loader fallback/rebuild |
+| World reset/shutdown | Loader lifecycle | Clear every reference/key | Shutdown regression | Refill during next session |
+
+There is no asynchronous work or cancellation token inside this service.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| `terrain_quality_mesh_cache_limit` | Existing loader value | `0/24/48` in current presets | Read on every store | Maximum retained entries |
+| Admitted source | Non-splat (currently `baked_full`) | All | No hidden override | Revisit retention |
+| Excluded sources | `control_splat_cache`, `splat_cache`, `splat` | All | No | Preserve active quality ownership |
+
+## Persistence, cache and migration
+
+- This is an in-memory reference cache, not a serialized cache format.
+- `REQUIRED_BAKED_TILE_FORMAT_VERSION=5`, control splat v3 and splat v1 remain
+  loader/resource validation contracts and are unchanged.
+- No migration or rebuild is required. Entry keys retain the existing tile-key form.
+
+## Diagnostics and observability
+
+- Detached diagnostics report count and oldest-to-newest tile key/source entries.
+- Mesh, material, Node and RID references are deliberately absent.
+- Performance is bounded dictionary lookup plus one ordered-array erase/append;
+  no new optimization or scale claim is made.
+
+## Verification
+
+- `verify_terrain_quality_mesh_cache.gd`: admission, exclusions, Mesh identity,
+  source, LRU touch/eviction, detached diagnostics, negative capacity and clear.
+- Loader source boundary proves cache composition/delegation and removal of its
+  former LRU array/touch/trim implementation.
+- Existing shutdown, facade, internal-access, manifest, planner and scheduler
+  regressions remain required.
+- Fidelity: source rules, capacities and three loader adapter sites are unchanged;
+  no visible terrain or build-12340 parity change is claimed.
+
+## Extension points
+
+- Expose scalar cache counts through facade metrics when needed.
+- Move additional terrain responsibilities only as separate bounded services.
+- Replace ordered-array LRU only after measured scale evidence.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Bounded quality Mesh retention | Implemented extraction | Contract/LRU fixtures | Asset-backed memory/revisit timing pending |
+| Deterministic reset ownership | Implemented | Clear path plus shutdown regression | Full terrain service still monolithic |
+| Persistent terrain cache formats | Unchanged | Loader version constants | Separate acceptance audit remains |
+
+## Known gaps and risks
+
+- Ordered-array touch is linear in entry count, matching prior behavior.
+- Mesh memory size is not measured; capacity remains entry-count based.
+- Only revisit Mesh ownership moved; build/tasks/state/finalization remain loader-owned.
+- Asset-backed flash/revisit timing and p95/p99 evidence remain pending.

+| Last verified | `a45d521`, 2026-07-14 |
+| Profiles/capabilities | Current sandbox ADT ground height; loaded-render-mesh diagnostic query; authoritative physics backend planned |
+
+## Purpose
+
+Provide a replaceable, scene-free ground-height query for player movement.
+Isolate native ADT loading, per-tile caching, chunk selection and legacy outer
+height-grid interpolation from the player scene behind a typed
+`GodotWorldPosition → TerrainGroundSample` contract.
+
+## Non-goals
+
+- Own player transforms, movement velocity or ground-snap policy.
+- Provide collision normals, slopes, holes, liquids, WMO/M2 collision or ray queries.
+- Change ADT topology, coordinate conversion, renderer caches or native parser format.
+- Claim original-client terrain-contact parity from height regression alone.
+- Couple gameplay to the monolithic streaming renderer before a public backend exists.

+- Existing native `ADTLoader` at the ADT adapter boundary.
+- Dynamic dictionaries only inside the native-format adapter.
+- Player scene composition may inject any `TerrainQuery` implementation.
+- Renderer diagnostics reuse `GodotWorldPosition` through `WorldRenderFacade`
+  but return renderer-owned `RenderedGroundSample`, preserving the render/gameplay boundary.
+
+Forbidden dependencies:
+
+- `TerrainQuery` contract depending on Nodes, cameras, input or renderer state.
+- Player scene loading/parsing ADT data or owning a parsed tile cache.

+|---|---|---|---|---|---|
+| Input | `GodotWorldPosition` | Player scene adapter | `TerrainQuery` | Immutable caller-held value | One query |
+| Input | Extracted directory/map name | Scene composition | `AdtTerrainQuery` | Copied strings | Query lifetime |
+| Input | ADT file/dictionary | Filesystem/native loader or injected loader | `AdtTerrainQuery` | Adapter-owned cached dictionary | Query lifetime |
+| Output | `TerrainGroundSample` | Terrain query | Player ground-snap adapter | Immutable caller-held value | One query |
+| Output | Failure code | Terrain query | Diagnostics/tests | Immutable `StringName` | Sample lifetime |
+
+Side effects:
+
+- Production adapter performs lazy file existence check and native ADT parse on first tile query.
+- Adapter mutates only its per-query tile/failure caches.
+- No scene tree, transform, renderer RID, network, database or persisted setting mutation occurs.

+```
+
+## Ownership, threading and resources
+
+- Player scene owns the active `TerrainQuery` reference.
+- `AdtTerrainQuery` exclusively owns tile/failure dictionaries until released.
+- Current production calls and cache mutations occur on the main physics thread.
+- Native loader result dictionaries do not cross the adapter boundary.
+- Samples and typed positions are immutable caller-held values.
+- The module creates no Nodes, Resources, RIDs or background jobs.
+- Future worker-backed queries require an explicit async/result contract rather
+  than concurrent mutation of the current dictionaries.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Base contract used directly | Base method | Unavailable sample | `terrain_query_not_implemented` | Inject implementation |
+| Native loader absent | ClassDB check | Cache unavailable tile | `adt_loader_unavailable` | Load extension and replace query |
+| ADT file absent | File check | Cache unavailable tile | `adt_source_missing` | Restore corpus and replace query |
+| Native parse empty/fails | Result validation | Cache unavailable tile | `adt_load_failed` | Inspect source/parser; replace query |
+| Injected loader returns wrong type | Type check | Cache unavailable tile | `adt_loader_result_invalid` | Fix adapter |
+| Chunk absent | Chunk lookup | Unavailable sample | `adt_chunk_missing` | Validate ADT dictionary |
+| Height array shorter than 145 | Size check | Unavailable sample | `adt_chunk_heights_invalid` | Fix parser/source |
+| Non-finite interpolated height | Sample invariant | Unavailable sample | `terrain_height_not_finite` | Inspect source values |
+| Null query injection | Scene guard | Existing query retained | Player composition error | Pass valid query |
+
+There are no asynchronous operations to cancel. Replacing/releasing the query
+is the deterministic cache-reset and recovery path.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Extracted directory | Player `extracted_dir` | Current sandbox | Captured at creation | ADT source root |
+| Map directory name | Player `map_name` | Current sandbox | Captured at creation | ADT filename/path |
+| Loader override | Invalid callable | Test/custom data source | Constructor only | Bypasses production ClassDB/file loading |
+| Tile cache | Enabled | All current uses | Cleared by replacing query | Avoids repeated parse/failure work |
+| Height policy | 9x9 outer-grid bilinear | Current sandbox | Fixed | Preserves pre-extraction behavior |
+
+## Persistence, cache and migration
+
+The cache is in-memory and unversioned because it holds native loader output for
+one query lifetime. No disk cache, schema or migration changes are introduced.
+Existing ADT/native/cache format versions remain unchanged.
+
+## Diagnostics and observability
+
+- Logs: dedicated verifier emits `TERRAIN_QUERY PASS` or named failures.
+- Structured status: every unavailable sample has a stable `failure_code`.
+- Metrics: synthetic verifier counts loader calls to prove one load per tile.
+- Debug views: none.
+- Correlation IDs: not applicable to synchronous local query.
+
+## Verification
+
+- Contract: available/unavailable/base/non-finite result invariants.
+- Pure synthetic adapter: typed coordinate mapping, exact chunk selection,
+  145-height layout and bilinear interpolation within `0.002` units (Vector3
+  source precision), plus cached second query.
+- Failures: empty tile and invalid height array produce stable codes.
+- Integration: asset-free player scene accepts injected flat query and preserves
+  spawn offset `0.05` plus physics ground snap.
+- Boundary: source regression rejects ADT loader/cache/chunk helpers in player.
+- Fidelity evidence: existing interpolation and snap behavior only; no
+  original-client or collision parity claim.
+- Performance budget: one dictionary cache lookup and scalar interpolation per
+  cached query; native parse only on first tile access.
+
+## Extension points
+
+- Streaming renderer or physics backend may implement `TerrainQuery` without changing player/movement.
+- The current facade intentionally uses a separate renderer-owned result and is
+  not a `TerrainQuery` implementation. A future adapter must explicitly translate
+  readiness/results and define gameplay authority before composition.
+- Future result may grow separate slope, surface, liquid or collision contracts;
+  incompatible additions require a versioned contract rather than Dictionary fields.
+- Test/authoring data sources may use constructor loader override.
+- Async streaming requires a separate availability/update model.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Typed replaceable ground-height query | Implemented | Contract and injected player regression | Integrate target checklist after review |
+| Existing ADT height interpolation | Implemented | Synthetic fractional-grid fixture | Compare terrain contact with build 12340 |
+| Per-tile success/failure cache | Implemented | Loader call-count regression | Add explicit invalidation only with authoring/hot reload |
+| Renderer loaded-mesh diagnostic backend | Implemented | M03 facade typed sample and detached snapshot contract | Not composed into gameplay; triangle Mesh ray is diagnostic only |
+| Authoritative renderer/physics backend | Planned | Boundary permits replacement | Define holes/slopes/collision/readiness semantics before gameplay composition |
+| Holes/slopes/collision | Planned | Outside height-only contract | Later movement/physics package |
+| Liquid/swim query | Planned | Outside contract | M09/M12 world gameplay |
+
+## Known gaps and risks
+
+- Bilinear outer-grid height is the inherited sandbox approximation; exact ADT
+  triangle choice, holes and collision are not represented.
+- Query is synchronous; first access may parse an ADT on the main thread exactly
+  as before extraction. A streaming/backend replacement is future work.
+- Unavailable results remain cached until query replacement.
+- Player still owns ground offset/snap policy; only data access is extracted.
+- Existing native dictionaries remain dynamic inside the adapter.

+
+## Ownership, threading and resources
+
+- Parent player scene owns the CameraPivot rig and Camera3D child.
+- Rig holds non-owning scene references to character and camera.
+- Rig owns scalar camera state and the RefCounted collision policy.
+- All input/state/scene mutations occur on the main thread.
+- Policy output is a scalar; policies must not mutate supplied nodes.
+- No background tasks, resources, RIDs or caches are created.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Camera3D missing | `_ready` lookup | State continues; transform application skipped | `ThirdPersonCameraRig` error with path | Restore child/path and recreate scene |
+| Character missing | Initialization | Orbit state updates without character yaw mutation | Composition/test failure | Call initializer with player node |
+| Null collision policy | Setter guard | Current policy retained | Rig error | Pass valid policy |
+| Policy returns negative/too large | Rig clamp | Distance clamped to `[0, requested]` | Policy regression tests | Fix/replace policy |
+| Rig removed while captured | `_exit_tree` | Mouse made visible | Lifecycle regression | Recreate rig normally |
+
+There is no asynchronous cancellation or persisted rollback. Recreating the rig
+restores configured defaults.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Initial pitch | `-18°` | Current sandbox | State-owned after ready | Initial orbit elevation |
+| Pitch limits | `-65°..35°` | Current sandbox | Exported | Mouse clamp |
+| Mouse sensitivity | `0.003` rad/pixel | Current sandbox | Exported | Orbit delta |
+| Pivot height | `1.7` units | Current sandbox | Exported | Camera eye origin |
+| Initial distance | `8` units | Current sandbox | Exported before ready | Requested zoom |
+| Zoom limits/step | `2..18`, step `1` | Current sandbox | Exported | Requested distance clamp |
+| Far plane | `50000` units | Renderer sandbox | Exported | Camera far plane |
+| Collision policy | `NoCameraCollisionPolicy` | Current sandbox | Replaceable | Identity distance/no raycast |
+
+## Persistence, cache and migration
+
+Camera state and policy are transient. No SavedVariables/settings schema, cache
+or migration is introduced. Scene paths remain
+`ThirdPersonPlayer/CameraPivot/Camera3D`, so renderer diagnostics and capture
+tools require no path migration.
+
+## Diagnostics and observability
+
+- Logs: missing camera/null policy emit explicit component errors.
+- Read models: yaw, pitch, requested/resolved distance and capture state.
+- Tests: dedicated verifier reports state/policy/scene counts.
+- Metrics/correlation IDs: not applicable to constant-time local presentation.
+
+## Verification
+
+- State regression: initial yaw/pitch/distance/height/far plane, capture/release,
+  mouse orbit, character yaw, pitch clamps and zoom clamps.
+- Input-profile integration verifies keyboard yaw synchronization, preventing a
+  later right-mouse orbit from restoring stale character yaw.
+- Policy regression: fixed-distance test policy changes Camera3D Z; identity
+  policy restores requested distance; baseline policy contains no physics query.
+- Scene integration: Eastern Kingdoms, Kalimdor and asset-free regression scenes
+  attach the rig to the existing CameraPivot.
+- Boundary: player no longer owns capture/yaw/pitch/distance or camera transform helper.
+- Existing input/movement/terrain regressions and renderer dry-run remain required.
+- Fidelity evidence: current numeric defaults and identity collision behavior
+  only; original-client orbit/collision comparison remains open.
+- Performance: constant-time scalar/transform work once per physics tick and
+  input event; no default raycast.
+
+## Extension points
+
+- Add an opt-in raycast collision policy after reference fixtures define mask,
+  margin, recovery smoothing and first-person limit.
+- Add follow/shoulder/cinematic rigs as separate components, not branches inside this rig.
+- Persist user camera settings through a future versioned settings module.
+- Input contexts may suppress camera actions before dispatch without changing rig state.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Independent third-person rig | Implemented | Three scene wirings and player boundary regression | Integrate target checklist after review |
+| Existing orbit/zoom behavior | Implemented | Numeric state/transform regression | Compare against build 12340 |
+| Camera-relative sandbox flight basis | Implemented | Basis and movement regressions | Restrict flight to sandbox profile |
+| Replaceable collision policy | Implemented | Fixed and identity policy tests | Implement verified collision policy |
+| Active camera collision | Planned | Identity policy intentionally preserves baseline | Capture original-client occluder fixtures first |
+| First-person/follow policies | Planned | Outside current sandbox baseline | Later completeness work |
+
+## Known gaps and risks
+
+- Default collision policy performs no occluder avoidance, matching the previous sandbox.
+- Exact WoW camera orbit direction, pitch limits, zoom curve, collision margin and
+  recovery smoothing are unverified.
+- Exported initial values are captured at ready; runtime mutation may require an
+  explicit reconfiguration API later.
+- Mouse mode remains process-global Godot state and must be coordinated with future UI contexts.

+
+## Ownership, threading and resources
+
+- The registry owns only placement-key Dictionaries and reference-key sets.
+- The loader owns the parallel placement-key-to-Node map and every Node action.
+- The loader also owns WMO roots, tile state, caches, requests, jobs, queues,
+  retries, cancellation and render-resource lifetime.
+- Current calls are serialized on the renderer main thread. The registry has no
+  lock and must not be mutated concurrently.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty placement/reference key | API guard | Reject without mutation | Contract verifier | Repair caller input |
+| Duplicate add | Existing set member | Idempotent retain | Sorted snapshot | No recovery required |
+| Unknown/non-owner release | Missing placement/reference | Ignore without mutation | Contract verifier | Release from actual owner or reset |
+| Tile build cancellation | Loader-owned condition | Loader cancels job, then releases recorded refs | Existing queue metrics | Retry when tile becomes wanted |
+| Final release | Empty set after erase | Return true and erase registry record | Active count | Loader cancels/free Node exactly once |
+| Map reset/shutdown | Loader lifecycle | Loader frees Nodes/jobs and clears registry | Shutdown regression | Next map begins empty |
+
+## Configuration and capabilities
+
+There is no setting, profile branch or capacity knob. WMO tile radius, cache
+limits, render budgets and visibility settings remain loader-owned.
+
+## Persistence, cache and migration
+
+No data is serialized and no cache/schema/version changes. Placement and
+reference keys exist only for the current renderer map session.
+
+## Diagnostics and observability
+
+`active_count` backs existing WMO instance metrics. `diagnostic_snapshot`
+returns deterministic detached records for tests and future read-only
+diagnostics; mutating the returned arrays cannot alter registry state.
+
+## Verification
+
+- `verify_wmo_placement_registry.gd`: invalid/first/idempotent/shared/non-owner/
+  final/global/clear behavior, deterministic detached diagnostics, source
+  ownership boundaries and bounded 100-by-256 shared-reference cycles.
+- WMO resolver, material, runtime-cache shutdown and the renderer regression
+  suite verify the unchanged loader adapters and surrounding lifecycle.
+- Fidelity evidence is exact preservation of the repository's prior shared-ref
+  and final-release semantics. Asset-backed 3.3.5a comparison is still pending.
+
+## Extension points
+
+- WMO build/resource state can be extracted separately without moving Nodes
+  into this registry.
+- A future diagnostic adapter may expose the detached snapshot through the
+  facade without exposing mutable loader internals.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| WMO placement reference ownership | Implemented extraction | Contract/source/timing verifier | Asset-backed cross-tile corpus pending |
+| WMO build/resource scheduling | Remains in loader | Existing runtime regressions | Separate state/cancellation package |
+| WMO visual/portal/material fidelity | Partial | Renderer baseline/material checks | Original-client paired evidence pending |
+
+## Known gaps and risks
+
+- Correctness assumes the loader records each successful placement reference in
+  the tile `wmo_refs` array before unregister.
+- Old caches without positive UID retain resolver-defined per-tile identity.
+- No proprietary WMO corpus or original-client paired capture is in this package.

+# WMO Placement Resolver
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | M03 / `M03-RND-WMO-PLACEMENT-RESOLVER-001` |
+| Owners | Pure WMO cache-key, placement-identity and world-transform rules |
+| Last verified | Worktree `work/sindo-main-codex/m03-wmo-placement-resolver`, 2026-07-17 |
+| Profiles/capabilities | Existing ADT/WDT WMO placement paths |
+
+## Purpose
+
+Provide one scene-free boundary for normalized WMO cache keys, MODF placement
+identity and world-space Godot transforms across render-cache, cached-scene and
+live-prototype instance paths.
+
+## Non-goals
+
+- Parse ADT/WDT or convert canonical WoW coordinates.
+- Own WMO registry references, tile state, jobs, queues or retries; reference
+  ownership belongs to `WmoPlacementRegistry`.
+- Load/validate cached scenes or lightweight render resources.
+- Create Nodes, Mesh/MultiMesh, materials or RIDs.
+- Implement portals, rooms, visibility, materials, doodads or WMO parity.
+
+## Context and boundaries

+
+Allowed dependencies are Dictionary/String values and Godot `Vector3`, `Basis`
+and `Transform3D` math. Node, SceneTree, RenderingServer, ResourceLoader,
+WorkerThreadPool, mutexes, files, gameplay, network and editor UI are forbidden.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `normalize_relative_path(relative_wmo_path)` | Pure query | Return lowercase slash-normalized cache/lookup key | Any thread; value result | Empty input returns empty |

+| `resolve_world_transform(placement)` | Pure query | Compose world-space position, Godot Euler rotation and uniform scale | Any thread; value result | Missing fields use zero/zero/one defaults; scale is not clamped |
+

+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Relative WMO path | WDT/ADT name table | Path normalizer | Caller String | One call |
+| Input | Raw placement Dictionary | WDT global or ADT MODF parser result | Identity/transform queries | Read-only shallow value | One call |
+| Input | Tile key and placement index | Loader build job | Synthetic identity fallback | Copied scalar/String | Registry entry lifetime |

+| Output | World `Transform3D` | Resolver | Three WMO instance adapters | Value copy | Instance lifetime after assignment |
+
+The resolver retains no source Dictionary, output or engine resource.

+```
+
+## Lifecycle/state
+
+The resolver is stateless. Construction, world reset, map switch, cancellation
+and shutdown require no resolver operation.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Loader as StreamingWorldLoader
+    participant Resolver as WmoPlacementResolver
+    participant Registry as WmoPlacementRegistry
+    participant Instance as Render/cached/live instance
+    Loader->>Resolver: normalize_relative_path(path)

+    Loader->>Resolver: resolve_world_transform(placement)
+    Resolver-->>Loader: value Transform3D
+    Loader->>Instance: assign transform and attach/build
+```
+
+## Ownership, threading and resources
+
+- The resolver owns only call-local scalar/value calculations.
+- `WmoPlacementRegistry` owns placement-key reference sets. The loader owns its
+  key-to-Node map, cache/load-request state, jobs/queues, resource fallback and
+  cancellation.
+- The loader and builders own every Node/Mesh/MultiMesh/material/RID lifecycle.
+- Pure calls are thread-safe; current consumers execute on the main thread.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty path | Empty String | Empty normalized key | Contract fixture | Loader cache path rejects/degrades |
+| Missing/non-positive UID | Integer rule | Tile/index key prevents same-tile collisions | Contract fixture | Rebake old ADT cache to restore cross-tile UID dedupe |
+| Missing transform fields | Dictionary defaults | Zero position/rotation; scale one | Contract fixture | Repair parser/cache input |
+| Zero/negative scale | No historical clamp | Preserve zero/mirrored basis | Contract fixture | Preserve source behavior |
+| Resource missing/pending | Outside resolver | Loader retry/fallback path unchanged | Existing loader diagnostics | Restore cache/raw asset |
+| Tile unregister/reset | Outside resolver | Loader releases refs/nodes/jobs | Shutdown/registry regressions | New placements resolve afresh |
+
+## Configuration and capabilities
+
+The resolver introduces no setting or profile branch. WMO radii, visibility,
+shadow/occlusion flags, cache size limits and build budgets remain loader-owned.
+
+## Persistence, cache and migration
+
+No format is written. Existing WMO `.tscn`/lightweight render cache versions and
+ADT/WDT formats are unchanged. Older placement caches without positive UID retain
+the existing per-tile fallback and require no migration for this extraction.
+
+## Diagnostics and observability
+
+The resolver emits no logs. Its verifier records path/identity/transform/source
+contracts and bounded 20,000-triple timing. WMO queue/cache/instance metrics remain
+in the facade/loader diagnostic snapshot.
+
+## Verification
+
+- `verify_wmo_placement_resolver.gd`: slash/case/empty path, positive UID,
+  missing/zero/negative UID fallback, default and rotated/scaled transform,
+  unclamped scale, historical Node3D property equivalence, stateless results,
+  all loader adapters, dependency boundary
+  and bounded timing.
+- Existing WMO material/cache/shutdown and renderer baseline regressions remain
+  required alongside M2/terrain/facade/internal-access/coordinate gates.
+- Fidelity evidence is exact extraction of current placement rules. No new
+  original-client WMO visual/portal/material parity claim is made.
+
+## Extension points
+
+- `WmoPlacementRegistry` consumes these stable keys; later packages may extract
+  WMO build/resource state without changing the resolver.
+- Render-group build cursor and resource-selection state require separate
+  lifecycle/cancellation contracts.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Consistent WMO placement identity/transform | Implemented extraction | Contract/source/timing verifier | Asset-backed placement comparison pending |
+| WMO placement registry | Implemented extraction | Ownership/source/timing verifier | Asset-backed cross-tile corpus pending |
+| WMO build services | Remains in loader | Existing runtime regressions | Stateful extraction pending |
+| Portals/rooms/material fidelity | Partial | M00 checkpoint/material evidence | Broader WMO implementation pending |
+
+## Known gaps and risks
+
+- Raw placement Dictionaries remain the parser/cache boundary.
+- Old caches without UID cannot dedupe one WMO across ADT tile boundaries.
+- WMO scale remains intentionally unclamped, including zero/negative input.
+- Asset-backed visual/p95/p99 evidence is unavailable in this package.

+
+## Purpose
+
+Own pending lightweight-WMO render build records and their FIFO placement-key
+order outside the monolithic loader. Each typed job retains its placement key,
+scene root, render resource and mesh/MultiMesh cursors while the loader performs
+all validation, planning, materialization, permit consumption and destruction.
+
+## Non-goals
+
+- Free or queue-free Nodes, Resources or RIDs.
+- Create MeshInstance3D/MultiMeshInstance3D or refresh materials.
+- Own frame permits, placement references, render cache state or load I/O.
+- Change duplicate enqueue, stale-key cleanup, cancellation or ordering.
+- Change cache versions, WMO transforms, shadows, visibility or fidelity rules.

+
+The queue may strongly reference Node3D and Resource through typed jobs, but it
+must not destroy, mutate or inspect their render content. RenderingServer, RID,
+Mesh/MultiMesh instances, files, worker threads, mutexes, gameplay, network and

+
+The queue can be `Empty`, `Pending` or `StaleFront`. Duplicate enqueue followed

+
+## Ownership, threading and resources
+
+- Queue owns its job Dictionary and FIFO key Array.
+- Job owns strong references, but loader owns Node/Resource semantic lifetime.
+- Loader checks `is_instance_valid`, creates/frees Nodes and controls caches.
+- Loader invokes planner and adopts cursor output on the main thread.
+- Queue/job contain no mutex; all mutation is serialized by the renderer drain.
+- `clear` may release the last Resource reference but never calls engine free APIs.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty key/null root/resource | Enqueue guards | Reject without mutation | Contract verifier | Repair caller input |
+| Duplicate key | Existing keyed job | Replace job and append key | Queue diagnostics | Historical stale handling remains |
+| Stale FIFO key | `job_for` returns null | Loader pops front without permit | Contract/source verifier | Continue drain |
+| Root invalidated externally | Loader validity check | Loader cancels keyed job | Shutdown/runtime diagnostics | Placement can rebuild later |
+| Resource absent | Loader check | Loader cancels keyed job | Runtime diagnostics | Reload/requeue placement |
+| Final placement release | Placement registry returns final | Loader cancels build then frees Node | Registry/shutdown regressions | Later placement starts fresh |
+| Reset/shutdown | Loader lifecycle | Queue clear releases references | Shutdown verifier | Next map starts empty |
+
+## Configuration and capabilities
+
+The module introduces no settings or profile branches. WMO group permit count,
+quality presets, cache limits, visibility and shadows remain loader-owned.
+
+## Persistence, cache and migration
+
+No data is serialized. WMO cache format/version/path and load request behavior
+are unchanged. No migration or cache rebuild is required.
+
+## Diagnostics and observability
+
+`pending_count` preserves existing queue metrics, including stale/duplicate keys.
+The detached snapshot exposes FIFO order, cursor values and root/resource presence
+without exposing mutable jobs or engine objects. No runtime logs are emitted.
+
+## Verification
+
+- `verify_wmo_render_build_queue.gd`: invalid inputs, FIFO, typed references,
+  cursor adoption, duplicate replacement, stale pop, first-key cancel, clear,
+  engine lifetime, detached sorted diagnostics, source boundaries and timing.
+- WMO planner/registry/resolver/material/shutdown and renderer regressions verify
+  unchanged ordering, permit use, destruction and surrounding lifecycle.
+- Fidelity evidence is exact preservation of current queue/Dictionary semantics;
+  no original-client visual or asset-backed performance claim is made.
+
+## Extension points
+
+- Cache/load-request ownership can be extracted separately without changing jobs.
+- A later typed materialization command may consume the borrowed job and planner
+  output while this queue remains the pending-state owner.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| WMO render build pending-state ownership | Implemented | Lifecycle/source/timing verifier | Asset-backed traversal/leak evidence pending |
+| WMO group planning | Implemented | Build-step planner verifier | Asset-backed p95/p99 pending |
+| WMO render Resource state | Implemented extraction | Cache-state lifecycle/source/timing verifier | Asset-backed traversal/leak evidence pending |
+| WMO materialization/cache I/O | Partial | Existing runtime regressions | Cached-scene and I/O seams remain |
+
+## Known gaps and risks
+
+- Jobs intentionally retain strong Node/Resource references until cancel/clear.
+- Duplicate enqueue preserves a stale-key edge case rather than normalizing it.
+- Resource array shape remains a WMO cache-builder invariant.
+- No proprietary WMO corpus, traversal profile or original-client paired capture
+  is included in this package.

+
+The planner depends only on `RefCounted`, integers, `StringName` and a fresh
+Dictionary result. Node, Resource, Mesh, MultiMesh, RID, SceneTree, files,
+threads, locks, caches, gameplay, network and editor UI are forbidden.

+
+The planner retains no input or output. Scene-tree mutation, material refresh,
+job writes, permit consumption and cancellation are loader side effects.
+
+## Data flow
+

+```
+
+## Lifecycle/state
+
+The planner is stateless. State belongs to the loader job. Repeated loader calls
+advance through `mesh` steps, then `multimesh` steps, then `complete`. Planner
+construction, cancellation, map reset and shutdown require no cleanup.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Loader as StreamingWorldLoader
+    participant Planner as WmoRenderBuildStepPlanner
+    participant Scene as SceneTree
+    participant Budget as RenderBudgetScheduler
+    Loader->>Planner: plan_step(counts, cursors)

+    end
+```
+
+## Ownership, threading and resources
+
+- The planner owns only call-local scalar comparisons and the returned value map.
+- `WmoRenderBuildQueue` owns typed jobs, FIFO keys and strong Node3D/Resource
+  references. The loader owns mesh-array interpretation and engine lifetime.
+- The loader creates and owns every MeshInstance3D/MultiMeshInstance3D and
+  performs material refresh and editor-owner assignment on the main thread.
+- `RenderBudgetScheduler` owns permits; the planner neither reads nor consumes one.
+- Pure calls are thread-safe because the planner has no mutable state.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty arrays | Both `0 < 0` comparisons false | Return `complete` | Contract verifier | Loader removes job |
+| Cursor at/beyond count | Raw integer comparison | Skip that range | Contract verifier | Continue next range or complete |
+| Negative cursor/count | Raw historical comparison | No clamp; select exactly as prior loader condition | Edge fixture | Caller should maintain valid job cursors |
+| Missing/invalid Resource | Loader validation before planning | Loader cancels job | Existing shutdown/runtime diagnostics | Reload/requeue placement |
+| Root freed | Loader validity check before planning | Loader cancels job | Runtime-cache shutdown verifier | Placement may rebuild later |
+| Placement final release | Loader/registry lifecycle | Loader cancels queued build | Registry regression | Later placement starts at cursor zero |
+
+## Configuration and capabilities
+
+The planner has no setting or profile branch. `wmo_render_group_ops_per_tick`,
+quality presets, shadow/visibility settings and cache limits remain loader-owned.
+
+## Persistence, cache and migration
+
+No data is persisted. WMO render resource format/version, cache path and job
+Dictionary fields are unchanged. No migration or cache rebuild is required.
+
+## Diagnostics and observability
+
+The planner emits no logs. Its verifier reports operation/cursor/source contracts
+and bounded timing. Queue lengths, active WMO count and hitch sections remain in
+existing loader/facade diagnostics.
+
+## Verification
+
+- `verify_wmo_render_build_step_planner.gd`: mesh-first order, cursor increments,
+  completion, empty and raw negative integer behavior, fresh results, loader
+  delegation, dependency boundary and 20,000-plan timing.
+- WMO registry/resolver/material/shutdown plus renderer regressions verify the
+  unchanged ownership and surrounding runtime path.
+- Fidelity evidence is exact extraction of existing mesh-before-MultiMesh and
+  one-index-per-permit behavior. No asset-backed build-12340 visual claim is made.
+
+## Extension points
+
+- `WmoRenderBuildQueue` now owns typed pending state; cache/load requests and
+  materialization remain separate extraction seams.
+- Materialization can later receive typed commands without changing this planner.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| WMO render build step planning | Implemented | Pure contract/source/timing verifier | Asset-backed traversal p95/p99 pending |
+| WMO build job/queue ownership | Implemented | Typed lifecycle/source/timing verifier | Asset-backed traversal/leak evidence pending |
+| WMO visual/portal/material fidelity | Partial | Renderer baseline/material checks | Original-client paired evidence pending |
+
+## Known gaps and risks
+
+- Loader build jobs remain untyped Dictionaries.
+- Resource array shape/length consistency remains a cache-builder invariant.
+- No proprietary WMO corpus, traversal profile or paired client capture is part
+  of this extraction.

+# WMO Render Resource Cache State
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | M03 / `M03-RND-WMO-RENDER-RESOURCE-CACHE-001` |
+| Owners | Validated lightweight-WMO render Resources, negative cache and pending request paths |
+| Last verified | Worktree `work/sindo-main-codex/m03-wmo-render-resource-cache`, 2026-07-17 |
+| Profiles/capabilities | Lightweight WMO render-cache path; profile-independent |
+
+## Purpose
+
+Own the mutually exclusive cached, missing and pending states for normalized
+lightweight-WMO render paths outside the monolithic streamer. The state holder
+accepts only caller-validated `Resource` references and records cache paths for
+threaded requests whose I/O lifecycle remains in `StreamingWorldLoader`.
+
+## Non-goals
+
+- Normalize WMO paths or construct `.res` cache paths.
+- Call `ResourceLoader`, inspect files or validate script/format versions.
+- Own WMO cached scenes, live prototypes, placements, build jobs or engine Nodes.
+- Change fallback order, retry timing, quality profiles or visible output.
+- Persist, migrate or build WMO caches.
+
+## Context and boundaries
+
+```mermaid
+flowchart LR
+    Placement[Normalized WMO render lookup] --> Loader[StreamingWorldLoader]
+    Loader --> State[WmoRenderResourceCacheState]
+    State -->|cached Resource| Loader

+    ResourceLoader -->|status and loaded Resource| Loader
+    Loader --> Validate[Script and FORMAT_VERSION validation]
+    Validate -->|accepted Resource or missing| State
+    Loader --> Fallback[Cached scene or live-prototype fallback]
+```
+
+The module may retain validated `Resource` references and copied path Strings.
+It has no FileAccess, ResourceLoader, Node, RID, worker, mutex, gameplay, network
+or editor dependency. Cache validation stays at the I/O boundary in the loader.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |

+## Data flow
+
+```mermaid

+    Lookup[Lookup normalized path] --> Cached{Cached?}
+    Cached -->|yes| Return[Return validated Resource]
+    Cached -->|no| Blocked{Missing or pending?}

+    Validate -->|valid| Adopt[complete with Resource]
+    Validate -->|invalid| Missing
+```
+
+## Lifecycle/state
+
+Each normalized path is `Absent`, `Pending`, `Cached` or `Missing`. Valid request
+completion leaves exactly one terminal state. Transient clear moves `Pending` and
+`Missing` to `Absent` but retains `Cached`; full clear moves every state to
+`Absent` and releases retained Resources.
+
+```mermaid
+stateDiagram-v2

+    Absent --> Pending: remember valid request
+    Pending --> Cached: validated Resource completion
+    Pending --> Missing: load/validation failure
+    Pending --> Absent: clear transient/full
+    Missing --> Absent: clear transient/full
+    Cached --> Absent: full clear

+        Loader->>State: complete with Resource or as missing
+    end
+```
+
+## Ownership, threading and resources
+
+- The state owns three Dictionaries and strong references to accepted Resources.
+- The loader owns normalization, cache paths, ResourceLoader calls and validation.
+- All mutation is serialized by the renderer main-thread lookup/drain lifecycle.
+- No mutex or callback is needed; detached request snapshots permit safe removal.
+- The loader/build queue borrow Resources without transferring ownership.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty path/cache path | Request guard | Reject unchanged | Contract verifier | Repair caller input |
+| Duplicate or occupied path | State membership | Reject request unchanged | Contract/source verifier | Await terminal/reset |
+| Threaded load failed | Loader status | Complete as missing | Existing renderer metrics | Transient reset permits retry |
+| Wrong script/old format | Loader validation | Complete as missing | Cache-version source gate | Rebuild cache, then reset |
+| Shutdown while pending | Loader drains ResourceLoader snapshot | Clear transient afterward | Shutdown verifier | Next runtime starts absent |
+| Final cache release | Loader shutdown lifecycle | Full clear releases Resources | Shutdown verifier | Recreated with loader |
+
+## Configuration and capabilities
+
+The module adds no setting or profile branch. `wmo_render_cache_dir`, resource
+format version, request scheduling and WMO build budgets remain loader-owned.
+
+## Persistence, cache and migration
+
+The state is runtime-only and serializes nothing. `WMOStreamingResource` script
+identity and `FORMAT_VERSION` validation remain unchanged in the loader; no cache
+migration or rebuild is introduced by this extraction.
+
+## Diagnostics and observability
+
+`pending_request_count` preserves the existing `wmobuild` metric contribution.
+Diagnostics expose only sorted normalized-path keys for cached/missing/pending
+states; Resource references and cache file paths are not exposed. No logs emit.
+
+## Verification
+
+- `verify_wmo_render_resource_cache_state.gd`: invalid input, detached requests,
+  successful/missing terminal transitions, exclusivity, partial/full reset,
+  sorted diagnostics, ownership/source boundary and bounded timing.
+- `verify_render_runtime_cache_shutdown.gd`: full release of accepted Resources
+  and negative state through the loader lifecycle.
+- WMO queue/planner/registry/resolver and surrounding renderer regressions verify
+  unchanged fallback/build behavior. This package makes no visual parity claim.
+
+## Extension points
+
+- Cached WMO scene request state is a separate typed module because its size
+  limit, PackedScene validation and missing-file behavior differ.
+- A later loader I/O adapter may consume the detached request snapshot while
+  preserving this state contract and cache-version boundary.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Lightweight WMO render Resource state | Implemented extraction | Lifecycle/source/timing and shutdown verifiers | Asset-backed traversal/leak evidence pending |
+| Cache script/version validation | Preserved in loader | Source boundary and WMO regressions | Dedicated corrupt-cache fixture could follow |
+| Cached WMO scene state | Implemented extraction | Scene-cache lifecycle/source/timing verifier | Asset-backed traversal/leak evidence pending |
+| WMO materialization | Partial/loader-owned | Queue/planner regressions | Further safe extraction |
+
+## Known gaps and risks
+
+- Strong Resource references live until final cache release, matching prior state.
+- Missing cache files remain unrecorded for render Resources, so lookup can retry;
+  this intentionally differs from the cached-scene path.
+- No proprietary WMO corpus, corrupt-version fixture, leak run, traversal p95/p99
+  or paired original-client capture is included.

+Each normalized path is `Absent`, `Pending`, `Cached` or `Missing`. Direct file,

+
+## Ownership, threading and resources
+
+- State owns three Dictionaries and strong references to accepted PackedScenes.
+- Loader owns paths, file measurement, requests, validation and all Node lifetime.
+- All mutation is serialized on the renderer main thread; no mutex is required.
+- Detached request snapshots allow terminal removal while polling.
+- Scene instantiation borrows the PackedScene and does not transfer cache ownership.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Recovery |
+|---|---|---|---|
+| Missing `.tscn` | Loader ResourceLoader existence check | Direct missing state | Transient reset permits later retry |
+| Oversize `.tscn` | Loader byte limit | Missing plus unchanged debug log | Raise limit/rebuild, then reset |
+| Request-start/load failure | Loader error/status | Direct or terminal missing | Reset and retry later |
+| Wrong type/stale metadata | Loader PackedScene/probe validation | Terminal missing; probe freed | Rebuild cache and reset |
+| Shutdown while pending | Loader drains snapshot | Clear transient, then full cache release | New loader starts absent |
+
+## Configuration and capabilities
+
+No setting is added. `wmo_cache_dir`, `wmo_max_runtime_scene_mb`, request timing,
+quality profiles and WMO build budgets stay loader-owned.
+
+## Persistence, cache and migration
+
+The module is runtime-only. Existing WMOBuilder cache metadata/version checks
+remain unchanged and execute before state adoption. No cache format, migration or
+rebuild is introduced.
+
+## Diagnostics and observability
+
+Pending count preserves the existing `wmobuild` metric contribution. The snapshot
+exposes sorted scene/missing/request keys only. Existing oversize logging remains
+in the loader; the state emits no logs.
+
+## Verification
+
+- `verify_wmo_scene_resource_cache_state.gd`: invalid input, direct missing,
+  exclusivity, request completion, partial/full reset, diagnostics, boundaries
+  and bounded timing.
+- `verify_render_runtime_cache_shutdown.gd`: loader full release of scenes,
+  negative and pending state.
+- Adjacent WMO/renderer regressions verify unchanged lookup/fallback behavior.
+  This extraction makes no visual or build-12340 parity claim.
+
+## Extension points
+
+- A later I/O adapter may consume request snapshots while retaining this contract.
+- Scene instantiation/material preparation can be extracted separately because it
+  owns Nodes and main-thread side effects rather than cache state.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Cached WMO PackedScene state | Implemented extraction | Lifecycle/source/timing and shutdown verifiers | Asset-backed traversal/leak evidence pending |
+| Size and cache metadata validation | Preserved in loader | Source boundary and WMO regressions | Oversize/stale asset fixtures could follow |
+| ResourceLoader I/O and live fallback | Partial/loader-owned | Existing runtime behavior | Separate extraction if justified |
+
+## Known gaps and risks
+
+- PackedScenes remain strongly referenced until final shutdown cache release.
+- Negative caching suppresses retries until transient reset, matching prior behavior.
+- No proprietary WMO corpus, stale/oversize asset fixture, leak run, traversal
+  p95/p99 or paired original-client capture is included.

+| Profiles/capabilities | Contract version 1; asset-free scene presentation only |
+
+## Purpose
+
+Accept immutable session-local entity visual snapshots through
+`WorldRenderFacade`, create or update renderer-owned visual subtrees idempotently,
+and remove them explicitly without making the renderer authoritative for entity,
+gameplay, network or content state.
+
+## Non-goals
+
+- Allocate `EntityId` or map it to `WowGuid`, display ID or server entry.
+- Present the separately composed local player through this service.
+- Define build-12340 model, equipment, animation, effects or visibility rules.
+- Own gameplay/world state, packet decoding, terrain or streaming decisions.
+- Provide asynchronous loading, pooling, batching, persistence or cache formats.
+
+## Context and boundaries

+
+Side effects:
+
+- synchronously loads a PackedScene only for first presentation or visual-path change;
+- instantiates, attaches, transforms, detaches and queues visual Node3D subtrees;
+- does not mutate authoritative state, streamer queues, caches, files, DB or network;
+- does not retain caller snapshots after an entity entry is replaced or removed.

+
+## Ownership, threading and resources
+
+- `EntityPresentationSnapshot` owns copied scalars/strings and immutable references
+  to caller-owned identity/position values; it owns no Node, Resource or RID.
+- `WorldEntityPresenter` owns its dictionary and every visual root attached below it.
+- A dictionary entry retains the latest snapshot only while the entity is presented;
+  diagnostics expose no Node, Resource or snapshot reference.
+- Scene load, instantiation, transform mutation, replacement and removal are main-thread only.
+- Successful replacement instantiates first, then detaches the previous root, so an
+  invalid/missing new asset cannot erase the last valid presentation.
+- Parent SceneTree teardown owns attached children; `_exit_tree` drops the index so
+  no stale lookup survives world unload.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Invalid identity/type | Snapshot/service validation | Reject without mutation | `entity_presentation_invalid_entity_id` | Supply valid session `EntityId` |
+| Non-finite position/yaw | Snapshot validation | Reject without mutation | Stable position/yaw failure code | Repair adapter read model |
+| Empty path or invalid scale | Snapshot validation | Reject without mutation | Stable path/scale failure code | Supply valid visual descriptor |
+| Missing/non-PackedScene asset | Resource existence/load check | New visual absent; old replacement retained | Named presenter warning | Restore asset mapping and resend snapshot |
+| Non-Node3D scene root | Instance type check | Free invalid instance; retain old | Named presenter warning | Fix visual scene root |
+| Unknown remove | Dictionary lookup | No mutation; return `false` | Caller command result | Reconcile registry/presentation lifecycle |
+| World teardown | Scene lifecycle | SceneTree frees children; index clears | Shutdown regression | Recreate service with next world |
+
+There is no background job to cancel. Synchronous asset load is an explicit
+prototype limitation and must be replaced/budgeted before network-scale use.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Contract version | `1` | All | No | Identity/path/position/yaw/scale/visibility full snapshot |
+| Present semantics | Idempotent by `EntityId` | Runtime/tools | No | Duplicate snapshots do not duplicate roots |
+| Resource loading | Synchronous on create/replace | Prototype only | No | Not accepted as frame-critical production path |
+| Local player | Separate composition | Current sandbox | No | Prevents facade service from owning gameplay player root |
+
+## Persistence, cache and migration
+
+- No snapshot, entity key or resource instance is persisted.
+- `EntityId` remains session-local and must never enter content/cache schemas.
+- Resource paths are current renderer adapter inputs, not stable content identity.
+- Contract version 1 is additive. Changing identity lifetime, coordinate basis or
+  persisted representation requires a migration and ADR.
+
+## Diagnostics and observability
+
+- `entity_presentation_snapshot()` reports contract version, entity count and a
+  sorted list of `EntityId.to_debug_key`, visual path and visibility.
+- The snapshot is deep-detached by the facade and contains no Node/Resource/RID.
+- Load/type failures include the visual path but never proprietary bytes.
+- Future performance telemetry should measure create/replace duration and active
+  entity/material/RID counts before introducing pooling or batching.
+
+## Verification
+
+- `src/tools/verify_world_entity_presentation.gd` covers eight value-contract and
+  fourteen lifecycle/ownership cases with repository-owned asset-free scenes.
+- `src/tools/verify_world_render_facade.gd` covers command delegation, detached
+  diagnostics and both runtime scene service paths.
+- Identity, coordinate, renderer-internal-access, shutdown, manifest, planner,
+  scheduler and documentation gates remain required.
+- Fidelity boundary: runtime emits no entity commands yet, so existing seven
+  checkpoint scenes remain unchanged. No build-12340 display/animation parity is claimed.
+
+## Extension points
+
+- AssetRepository/display-ID adapter that produces validated visual descriptors.
+- Async/budgeted load and main-thread finalize behind the same facade commands.
+- Animation/equipment/effect snapshots after build-12340 fixtures define behavior.
+- Spatial batching/MultiMesh only after profiling proves per-Node overhead.
+- Entity registry adapter that maps `WowGuid` to session `EntityId` outside render.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Typed entity visual input | Implemented contract | Versioned immutable validation fixtures | Asset/display mapping not implemented |
+| Present/update/remove lifecycle | Implemented boundary | Asset-free create/update/replace/remove tests | Network-scale async/budget path missing |
+| Deterministic ownership | Implemented | One presenter-owned root per EntityId; teardown checks | RID/material budgets remain future work |
+| WoW entity visual fidelity | Planned | No claim | Requires build-12340 display/equipment/animation fixtures |
+
+## Known gaps and risks
+
+- Synchronous PackedScene load may hitch and is not a production hot-path design.
+- Resource path is renderer adapter data, not stable authored content identity.
+- Full snapshots currently cover transform/visibility only, not animation/equipment/effects.
+- One Node3D per entity is unprofiled at world scale; batching is deliberately deferred.
+- The local player remains separately composed until gameplay/network architecture is ready.

 ## Public API
 
-Текущая система ещё не имеет стабильного facade. Фактический integration surface — `StreamingWorldLoader` Node3D и exported properties. M03 должен заменить этот surface на `WorldRenderFacade`.
+Runtime, capture and probe callers use `WorldRenderFacade` for focus, immutable
+environment/entity presentation input, metrics and rendered-ground diagnostics.
+`StreamingWorldLoader`, `WowSkyController` and `WorldEntityPresenter` remain
+internal scene implementations.
+Gameplay modules and Godot `EditorPlugin` package sources are repository-gated
+from externally reading/writing loader-private queue, task, cache and tile-state fields.

 ## Ownership, threading and resources
 
 - `StreamingWorldLoader` владеет tile states, queues, task registries, active world instances и render caches session scope.
+- `WorldRenderFacade` owns only scene-relative adapter paths. It does not own the
+  streamer, environment controller, focus source, returned metrics, queues,
+  caches, nodes or RIDs.
+- `WorldEnvironmentSnapshot` is an immutable caller-owned scalar value. Neither
+  facade nor sky controller retains it; the controller copies normalized hours
+  into its existing fixed-clock fields on the main thread.
+- `WowSkyController` continues to own DBC sampling state and mutations of its
+  duplicated Godot `Environment`, sun, skybox node and world shader globals.
+- `WorldEntityPresenter` owns one optional visual Node3D subtree per presented
+  `EntityId`; it owns no authoritative entity state and excludes the local player.
+- Entity presentation snapshots remain caller-owned inputs. Detached diagnostics
+  expose only identity debug keys, paths and visibility, never Node/Resource/RID.
+- `TerrainQualityMeshCache` owns only full-quality revisit Mesh references and
+  LRU keys. The loader retains terrain tasks/results, tile state, source choice,
+  cache versions and every material/Node/RID finalization side effect.
+- `TerrainChunkLodPlanner` is stateless and owns only call-local horizontal
+  distance calculations. The loader retains parsed chunks, desired state,
+  queues, budgets and all Mesh/Node/RID application side effects.
+- `TerrainChunkGeometryQueuePlanner` is stateless and owns only call-local
+  create/remove request calculation and sorting. The loader adopts the fresh
+  arrays and retains removal-first drains, budgets and render side effects.
+- `M2UniquePlacementRegistry` owns only positive unique-key to tile-key strings.
+  The loader retains owned/skipped tile arrays, candidate retry, grouping/build
+  tasks, caches and all MultiMesh/Node/Mesh/material/RID side effects.
+- `M2PlacementTransformResolver` is stateless and retains no resources. The
+  grouper owns worker-path final transforms; direct placeholder/instance
+  transforms and every build/render side effect remain loader-owned.
+- `M2PlacementGrouper` is stateless and owns only call-local grouped transforms.
+  The loader retains tasks, mutex/result queues, stale checks and build state.
+- `M2BuildBatchPlanner` is stateless and owns only call-local scalar plans. The
+  loader retains queue/resource transitions, cursor adoption and materialization.
+- `WmoPlacementResolver` is stateless and owns only call-local cache-key,
+  identity and transform values. `WmoPlacementRegistry` owns only placement-key
+  reference sets. `WmoRenderBuildStepPlanner` owns only a call-local operation
+  and cursor plan. `WmoRenderBuildQueue` owns typed pending jobs, FIFO keys and
+  strong root/resource references without freeing engine objects.
+  `WmoRenderResourceCacheState` owns validated render Resources, negative entries
+  and pending cache paths. `WmoSceneResourceCacheState` similarly owns validated
+  PackedScenes, negative entries and pending `.tscn` paths. The loader retains
+  ResourceLoader/FileAccess I/O, size and cache-version validation, live fallback,
+  materialization, permits, validity reactions and every Node lifecycle action.
+- `AdtWaterLoadPipelineState` owns pending request order/deduplication, opaque
+  active task IDs and the worker-safe parsed-result mailbox. The loader retains
+  WorkerThreadPool start/wait, ADTLoader parsing, concurrency/finalize permits,
+  stale tile/path/root checks and `water_loaded` timing. `AdtWaterSceneFinalizer`
+  performs the existing ADTBuilder call, tile attach and optional recursive
+  Editor ownership on the main thread without retaining the generated subtree.
+- `M2RuntimeMeshRebuildClassifier` owns only normalized-path boolean decisions
+  for billboard/UV-rotation material refresh. The loader retains raw M2 loading,
+  refresh-version checks, Mesh rebuild/adoption and both historical clear sites.
+- Rendered-ground query results and diagnostic snapshots are caller-owned values;
+  the facade never returns Mesh, Node, tile-state or queue references.
+- Loaded-mesh ground sampling is renderer diagnostics, not authoritative gameplay
+  collision. M02 `TerrainQuery` composition and ADT cache ownership remain unchanged.
+- `StreamingTargetPlanner` is stateless and owns only call-local calculations;
+  its immutable plan is consumed synchronously by the streamer.
+- `RenderBudgetScheduler` owns only per-frame lane counters and a terminal
+  cancellation flag. The streamer retains queue ordering and all operation side effects.
+- Focus producers own the immutable `StreamingFocus` reference; the loader retains
+  the latest reference and converts it to `Vector3` only inside the render boundary.
 - Worker tasks не должны менять SceneTree и shared Resource concurrently.
 - Parsed/grouped results передаются обратно через guarded result queues.
 - Mesh/material/node/RID finalization выполняется main thread и ограничивается exported budgets.
-- Shutdown/map switch обязан отменить/дождаться jobs и освободить RIDs; M00 всё ещё фиксирует leaked-resource risk.
+- Shutdown/map switch обязан дождаться WorkerThreadPool jobs и зарегистрированных threaded ResourceLoader requests до очистки очередей, nodes, caches и RIDs.
+- Parented streamed nodes остаются owned by SceneTree during shutdown; detached M2/WMO prototype caches are explicitly `free()`d after asynchronous work drains.
+- A temporary liquid root with no generated child geometry is explicitly freed by `ADTBuilder` instead of being returned or abandoned.
 - Cache resources считаются immutable после публикации.

 - Performance budgets: M00 report records cold/warm p95 and max hitch; no final acceptance threshold yet.
 - Manual diagnostics: [`../RENDER_BASELINE.md`](../RENDER_BASELINE.md) and [`../../RENDER.md`](../../RENDER.md).
 
 ## Extension points
 
 - Target `WorldRenderFacade` for runtime/editor/capture callers.
-- Target `StreamingFocus` independent of Camera3D.
+- Extend `StreamingFocus` with measured direction/velocity needs when the pure planner is extracted.
 - Extracted planner, budget scheduler, terrain, M2, WMO, liquid, sky and character services.
 - Separate Blizzlike/Enhanced material and quality profiles.

 ## Known gaps and risks
 
 - Monolithic streamer mixes planning, jobs, caches and presentation.
-- Direct camera path remains until M01/M03.
+- `camera_path` remains only for optional automatic overview positioning; it no
+  longer drives runtime streaming or discovers the active viewport camera.
 - Original-client paired fidelity evidence incomplete.
 - Первый paired run выявил coordinate/placement mismatch: несколько совпадающих server-derived camera positions оказываются под terrain или внутри WMO/rocks OpenWC.
-- D3D12 descriptor and shutdown RID/resource issues remain.
+- Terrain-height probe исключил under-terrain состояние для всех пяти точек; waterfall exact-XZ miss классифицирован как TriangleMesh seam/edge и подтверждён nearby sample в 2 units.
+- Camera-occluder probe не нашёл camera containment в пяти точках; paired mismatch локализован прежде всего в manual look direction/target/FOV calibration, с явным ограничением по RID-only geometry.
+- Empirical FOV sweep выявил, что checkpoint camera должна явно вызывать `make_current()`; после исправления projection ranking остаётся inconclusive из-за неизвестного manual yaw/pitch/framing reference.
+- Camera-pose sweep can now rank bounded yaw/pitch grids without changing manifest defaults; perceptual ranking remains diagnostic and requires human framing approval.
+- The first Goldshire pose grid was invalidated by WMO readiness: the inn is absent after 2 seconds but visible after the manifest-standard 8-second wait. Pose comparisons must stabilize asynchronous checkpoint content first.
+- A ready-scene Goldshire 3x3 grid improved mean error from `0.101402` at zero offsets to `0.087952` at yaw `10`/pitch `-10`; pitch/FOV refinement remains required before manifest calibration.
+- Joint Goldshire pitch/FOV refinement had no human-approved optimum: full-frame error preferred grass-heavy FOV 62/pitch -25, while FOV 38/pitch -10 better matched building scale. Landmark/region scoring is required before calibration.
+- Common-region scoring `[300,100,1400,650]` moved Goldshire's numeric optimum to FOV 38/yaw 10/pitch -15, but human inspection still found an oversized/cropped facade; semantic landmarks or masks remain required.
+- Final paired audit compared fourteen cold/warm images for seven private build 12340 references with zero missing pairs; mean error ranges `0.066893..0.176955`. Animated-M2 native motion is observed across two original-client phases, but its real Lakeshire placement differs from the synthetic Goldshire probe. Sky-transition evidence uses the checkpoint map position/time with manually approved approximate framing.
+- D3D12 descriptor issues remain. Explicit shutdown ownership removes the GUI capture's Node/resource/RID leaks in focused and seven-checkpoint runs; a timing-dependent ObjectDB warning for anonymous zero-reference `RefCounted` objects remains as a separate engine-teardown diagnostic.
 - M2/WMO/material/particle/ribbon/portal parity incomplete.
 - Public API is mostly exported configuration rather than stable contracts.
+- Rendered-ground sampling generates a triangle mesh on demand and retains the
+  historical nearby seam fallback. It is appropriate for diagnostics, not a
+  per-physics-frame gameplay query or a claim of exact terrain collision parity.
