+## 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 requests raw M2 data and owns ResourceLoader,
+  returned-Mesh adoption and finalization budgets. Refresh-version checks,
+  M2Builder rebuild and fallback now belong to `M2RuntimeMeshFinalizer`.
+- 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 M2 Mesh Load Pipeline State Extraction
+
+- `M2MeshLoadPipelineState` now owns static M2 successful threaded-load request
+  records and the FIFO populated when ResourceLoader polling reaches loaded or
+  failed terminal status.
+- Pending polling snapshots preserve Dictionary insertion order; terminal FIFO
+  order follows completion transition order. Existing `m2_mesh` metrics still
+  count pending plus finalize records at all three sites.
+- Shutdown still drains every pending ResourceLoader path before state clear;
+  map reset and shutdown retain the same two clear sites.
+- `StreamingWorldLoader` still selects `.tscn`/`.glb` paths, excludes animated
+  pivot-prefix GLBs, performs all ResourceLoader calls, consumes
+  `M2_MESH_FINALIZE`, extracts/prepares Meshes and updates Mesh/missing caches.
+- Cache formats, material refresh, profiles and visible output are unchanged.
+  Synthetic state timing is not asset-backed I/O, leak or p95/p99 evidence.
+
+## 2026-07-17 M2 Animation Load Pipeline State Extraction
+
+- `M2AnimationLoadPipelineState` now owns animated M2 successful threaded-load
+  request records and the FIFO populated at loaded/failed terminal transitions.
+- Pending snapshots preserve insertion order, while finalization follows completion
+  order. All three historical `m2_animation` metrics still count both stages.
+- Shutdown still drains pending ResourceLoader paths before clear; map reset and
+  shutdown preserve the same two clear sites.
+- `StreamingWorldLoader` retains GLB eligibility/cache selection, every
+  ResourceLoader call, `M2_ANIMATION_FINALIZE` permits, scene instantiation,
+  material repair and prototype/static-fallback decisions.
+- Cache formats, animation behavior and visible output are unchanged. Synthetic
+  timing is not asset-backed I/O, leak, animation-fidelity or p95/p99 evidence.
+
+## 2026-07-18 M2 Animated Scene Finalizer Extraction
+
+- `M2AnimatedSceneFinalizer` now owns terminal animated PackedScene candidate
+  instantiation, depth-first Mesh/AnimationPlayer traversal, static-prototype
+  material override mapping and rejected detached-root destruction.
+- Material repair retains source/target depth-first ordering, source-index clamp,
+  per-surface override priority and first discovered material fallback.
+- A candidate still requires at least one AnimationPlayer. Accepted exact Node3D
+  and player count return to the loader; invalid candidates are freed, including
+  the previously unhandled non-Node3D imported-root case.
+- `StreamingWorldLoader` retains ResourceLoader I/O/statuses, finalize permits,
+  material-prototype selection/loading, prototype adoption/static fallback,
+  animation playback policy and diagnostic logging.
+- Cache formats, profiles and visible rules are unchanged. Synthetic scene and
+  material fixtures are not asset-backed animation-fidelity or p95/p99 evidence.
+
+## 2026-07-18 M2 Animation Playback Controller Extraction
+
+- `M2AnimationPlaybackController` now owns the stable path/index phase formula,
+  ordinary/fish/bird animation-name priority, substring/first-name fallbacks and
+  AnimationPlayer linear-loop/play/seek mutation.
+- Exact-script native animators retain depth-first pairing, the same five copied
+  fields, optional `prepare_runtime`, phase assignment and debug-state sampling.
+- Native debug records are detached and sampled only when `debug_streaming` is
+  enabled; `StreamingWorldLoader` retains path normalization and exact log text.
+- Loader still duplicates/transforms/attaches instances, applies visibility,
+  shadows and Editor ownership, owns build cursors/permits and obtains player inventory.
+- Cache formats, playback priorities, phase behavior and visible rules are unchanged.
+  Synthetic timing is not asset-backed animation fidelity or p95/p99 evidence.
+
+## 2026-07-17 M2 Mesh Resource Cache State Extraction
+
+- `M2MeshResourceCacheState` now owns normalized-path references to prepared
+  static M2 Mesh resources. Lookup returns the exact retained reference and a
+  later store for one path keeps the historical replacement behavior.
+- The cache retains map-refresh lifetime and clears only at the existing final
+  runtime-cache shutdown site after asynchronous work is drained.
+- `StreamingWorldLoader` still owns normalization, `.tscn`/`.glb` selection,
+  ResourceLoader I/O, Mesh extraction, material refresh/rebuild, cache adoption
+  decisions, permits and MultiMesh materialization. Prototype/negative state is
+  now a sibling cache service.
+- Cache formats, refresh metadata, profiles and visible output are unchanged.
+  Synthetic cache timing is not asset-backed memory/leak or p95/p99 evidence.
+
+## 2026-07-17 M2 Mesh Resource Extractor
+
+- `M2MeshResourceExtractor` now selects the first Mesh from direct Mesh
+  Resources, temporary PackedScene instances and existing prototype/rebuild
+  Node subtrees using the prior depth-first child order.
+- PackedScene extraction still instantiates exactly once and synchronously frees
+  the temporary root before returning the borrowed Mesh reference.
+- `StreamingWorldLoader` still owns ResourceLoader I/O and raw M2 consumers,
+  material refresh/rebuild, cache/missing adoption, permits and MultiMesh builds.
+- Cache formats, traversal rules, profiles and visible output are unchanged.
+  Synthetic traversal timing is not asset-backed leak or p95/p99 evidence.
+
+## 2026-07-17 M2 Runtime Mesh Finalizer
+
+- `M2RuntimeMeshFinalizer` now owns material refresh version `2`, stale-Mesh
+  rebuild classification, M2Builder rebuild and original-Mesh fallback.
+- Current Meshes still skip raw `.m2` loading. `M2RawModelRepository` now owns
+  FileAccess/ClassDB M2Loader I/O and supplies raw data through the loader only
+  when the finalizer reports a stale Mesh; both historical clear sites persist.
+- Billboard/UV-rotation predicates, rebuild extraction, metadata key and failure
+  fallback are unchanged. Cache adoption decisions, permits and MultiMesh
+  materialization remain loader-owned; negative outcomes belong to prototype state.
+- Synthetic triangle rebuild/fallback timing is not asset-backed material,
+  descriptor-pressure/leak or p95/p99 evidence.
+
+## 2026-07-17 M2 Raw Model Repository
+
+- `M2RawModelRepository` now owns the repeated extracted-file and optional
+  native `M2Loader` boundary for static `load_m2` and animated
+  `load_m2_animated` raw Dictionaries.
+- `StreamingWorldLoader` delegates the stale-Mesh refresh, static prototype and
+  native animated prototype reads. It retains normalization, `.tscn/.glb`
+  fallback order, builders, permits and Node/Mesh use; prototype/negative state
+  is now isolated in `M2PrototypeCacheState`.
+- The repository retains no path, native object or parsed data. Empty paths,
+  absent files/classes/methods and invalid results produce the same empty-value
+  fallback contract; path join/globalization and native method names are exact.
+- No cache format, parser, material, geometry, animation or visible rule changed.
+  Synthetic missing-input timing is not asset-backed I/O/p95/p99 or fidelity evidence.
+
+## 2026-07-17 M2 Prototype Cache State
+
+- `M2PrototypeCacheState` now owns the exact static and animated prototype Node
+  references plus missing-model and static-animation negative path outcomes.
+- Sync static, native animated, threaded GLB animation, Mesh finalize and
+  material-prototype paths delegate lookup/adoption/negative transitions to the
+  service. First valid prototype remains canonical for each normalized path.
+- Map refresh still retains all four states. Final shutdown still occurs after
+  asynchronous drain and now calls one idempotent release operation that frees
+  detached prototypes, queues defensive in-tree Nodes and clears path outcomes.
+- `StreamingWorldLoader` retains normalization, ResourceLoader/native I/O,
+  builders, animation policy, fallback order, permits and materialization.
+- No cache format, visible rule or profile changed. Synthetic ownership/timing
+  evidence is not an asset-backed traversal/leak/p95/p99 or fidelity claim.
+
+## 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
+
+Support a bounded empirical FOV sweep when build 12340 does not expose a readable camera FOV CVar.
+
+## Non-goals
+
+- Claiming exact WoW FOV from a single manually aimed screenshot.
+- Changing runtime player camera defaults.

+
+- Exclusive: FOV/filter CLI additions in checkpoint tools
+- Shared/hotspots: renderer baseline documentation

+
+## Outcome
+
+Identify ownership of GUI render-baseline shutdown leaks and apply the smallest regression-covered fix that lets queued world resources release before engine teardown.
+
+## Non-goals
+
+- Renderer architecture decomposition.
+- Hiding or filtering Godot leak diagnostics.
+- Changing M00 status, Evidence or `OPENWC_TARGET_DONE`.
+
+## Paths

+- Exclusive: capture shutdown sequencing and its regression diagnostic

+- External state: proprietary references are not required for the focused shutdown regression
+
+## Verification
+
+- Commands: focused GUI single-checkpoint capture with verbose shutdown, headless project load, manifest/self-tests, repository gates
+- Fixtures: existing non-proprietary render-baseline manifest and local extracted corpus
+- Fidelity evidence: no visual behavior change; focused PNG hash/report remains valid
+- Performance budget: shutdown-only change

+- Inline public API docs: shutdown method semantics if introduced
+- Module specification: shutdown ownership and observed leak status
+- Data-flow diagram: unchanged
+- Sequence/state/dependency diagrams: update shutdown sequence only if behavior changes

+
+## Simplicity and naming
+
+- Important names introduced: `_release_runtime_caches_for_shutdown`, `_free_detached_node_cache`, `_queue_free_streamed_node`
+- Simplest considered solution: explicitly release capture-owned scene references and drain deferred deletion
+- Rejected complexity/abstractions: global RID registry or suppressed engine diagnostics
+- Unavoidable complexity and justification: async streaming jobs must finish before resource ownership can drain
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: reproduced the focused leak; assigned detached prototype/resource caches and empty liquid roots to explicit owners; added a headless regression; verified zero Node/resource/RID leak lines in focused and seven-checkpoint GUI captures
+- Next: integrator review and disposition of the residual engine-level zero-reference `RefCounted` diagnostic
+- Blocked by:
+
+## Handoff
+
+- Commit: this work-package commit
+- 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
+- Source map/status updates: camera-pose operational guide
+
+## Simplicity and naming
+
+- Important names introduced: none
+- Simplest considered solution: reuse the manifest's measured 8-second stabilization default

+- Unavoidable complexity and justification: WMO publication is asynchronous
+- Measured optimization evidence: 2/8/15 second snapshots
+
+## Status
+
+- State: ready-for-review
+- Done: timing audit invalidated the 2-second evidence; sweep default now matches the 8-second manifest; ready-scene 3x3 grid and human inspection completed

+
+## 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.

+- 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

+- 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`,

+- 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

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

+- 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

+- Unavoidable complexity and justification: three independent source categories need explicit provenance
+- Measured optimization evidence: not applicable
+
+## Status

+- 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

+- 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

+- 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

+- 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.

+## Outcome
+
+Route the pinned AzerothCore Human Warrior spawn fixture through

+ADT tile/chunk.
+
+## 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

+## 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.

+  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

+## Status

+- 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.

+- 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`

+  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

+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.
+- Remove debug Input Map actions or change their current sandbox bindings.
+- Implement jump, fall, swim, collision, server authority or reconciliation.
+- Mark M02 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/gameplay/movement/player_movement_capabilities.gd`,
+  `src/tools/verify_player_movement_capabilities.gd`, this claim
+- Shared/hotspots: `src/gameplay/movement/local_player_movement_controller.gd`,
+  `src/scenes/player/third_person_wow_controller.gd`, movement/input verifiers,
+  player regression scene, `docs/modules/local-player-movement.md`,
+  `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`
+- Blocked by:

+
+## 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.

+
+## Outcome
+
+Introduce a typed `TerrainQuery` boundary and move ADT loading, caching, chunk

+
+## Non-goals
+

+- Reuse the streaming renderer cache before its public terrain-query contract exists.
+- Extract camera or character presentation.

+- 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

+
+## Non-goals
+
+- Change player, movement, terrain, camera, presentation or renderer behavior.

+
+## 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.

+  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

+## 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.

+components without changing the current sandbox presentation.
+

+- 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
+

+
+## 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.

+
+<!-- OPENWC_CLAIM:M03-RND-ADT-WATER-LOAD-PIPELINE-001:sindo-main-codex:2026-07-20 -->

+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-adt-water-load-pipeline`
+- Lease expires UTC: 2026-07-20
+- Integrator: M03 milestone integrator
+
+## 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.
+
+## Paths
+
+- Exclusive: `src/render/liquid/adt_water_load_pipeline_state.gd`,
+  `src/tools/verify_adt_water_load_pipeline_state.gd`,
+  `docs/modules/adt-water-load-pipeline-state.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,
+  `src/tools/verify_render_runtime_cache_shutdown.gd`,
+  `docs/modules/world-renderer.md`, `docs/modules/README.md`, `RENDER.md`,
+  `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
+
+## Status
+
+- State: accepted
+- Done: pipeline state implemented; loader enqueue/start/publish/drain/release/
+  reset/shutdown/metrics adapters migrated; required documentation added
+- Next: continue liquid parse/finalization extraction or another remaining M03
+  service boundary
+- Blocked by:

+
+## Handoff
+
+- Commit: `b7c036f`
+- Results: water pipeline PASS (`cases=12`, `iterations=100`,
+  `elapsed_ms=86.170`; initial direct cold run `94.576ms`); real Thread result
+  publication, FIFO/dedupe/task/cancel/clear/source contracts PASS; WMO caches/
+  queue/planner/registry/resolver, materials, shutdown and 18 adjacent M2/terrain/
+  facade/scheduler/streaming/coordinate regressions PASS; documentation and
+  coordination gates PASS; checkpoint dry-run PASS `7/7`.
+- Remaining risks: clear does not interrupt active WorkerThreadPool work and a
+  post-reset publication remains stale until drained/cleared, matching prior
+  behavior; payload Dictionaries require no mutation after publication; parser,
+  main-thread water materialization and asset-backed MH2O/MCLQ traversal/leak/
+  p95/p99/original-client evidence remain pending.
+- Documentation updated: inline public API; new
+  `docs/modules/adt-water-load-pipeline-state.md`; module registry, world renderer
+  and `RENDER.md`; data-flow/state/sequence/dependency diagrams, ownership,
+  threading, failure/recovery, profiles, performance limit and source map included.
+- Integration: merged as `f470775`; post-merge water pipeline (`cases=12`,
+  `iterations=100`, `elapsed_ms=86.935`), shutdown, renderer materials, facade,
+  internal-access (`private_symbols=36`), `7/7` manifest, documentation and
+  coordination gates passed.

+- Branch: `work/sindo-main-codex/m03-adt-water-scene-finalizer`
+- Lease expires UTC: 2026-07-20
+- Integrator: M03 milestone integrator
+
+## 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
+
+- Exclusive: `src/render/liquid/adt_water_scene_finalizer.gd`,
+  `src/tools/verify_adt_water_scene_finalizer.gd`,

+  `targets/03-renderer-facade.md`
+- 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
+
+## Simplicity and naming
+
+- Important names introduced: `AdtWaterSceneFinalizer`
+- Simplest considered solution: one RefCounted with one explicit attach operation
+- Rejected complexity/abstractions: generic scene finalizer, signals, callbacks,
+  builder interface, queue ownership or alternate liquid renderer
+- Unavoidable complexity and justification: editor-persisted generated subtrees
+  require recursive owner assignment after SceneTree attachment
+- Measured optimization evidence: bounded synthetic no-water loop
+
+## Status
+
+- State: accepted
+- Done: stateless finalizer implemented; both loader water paths migrated;
+  synthetic scene/owner regression and required documentation added
+- Next: continue liquid parsing/task execution extraction or another remaining M03 boundary
+- Blocked by:
+
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-ADT-WATER-SCENE-FINALIZER-001:874fd0f -->
+
+## 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,
+  ownership, main-thread effects, failure/recovery, migration and source map included.
+- Integration: merged as `874fd0f`; post-merge finalizer (`cases=8`,

+  renderer materials, facade, internal-access (`private_symbols=36`), `7/7`

+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- 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 -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-FACADE-001:a100ced -->
+
+## 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.

+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Add immutable, versioned world-entity presentation input and stable facade
+commands for idempotent present/update and removal, backed by a renderer-owned
+scene service with explicit entity subtree ownership.
+
+## Non-goals
+
+- Define authoritative entity/gameplay/network state or allocate/map identities.
+- Move the local player controller/presenters behind the world-entity service.
+- Implement build-12340 display IDs, equipment, animation, effects or visibility rules.
+- Add background loading, pooling, MultiMesh conversion or a generic ECS/framework.

+
+## Paths

+  `docs/modules/README.md`, `RENDER.md`, `targets/03-renderer-facade.md`
+- 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`,
+  `present_entity`, `remove_entity`
+- 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
+
+- State: ready-for-review
+- Done: immutable contract-v1 snapshot, presenter ownership lifecycle, facade
+  commands, runtime composition, asset-free regressions and module documentation
+- Next: M03 integrator reviews and merges `1807c3a`

+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-FACADE-ENTITY-001:606770c -->
+
+## 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
+  `43/7/9/1`; environment/ground/terrain, manifest `7/7`, shutdown, scheduler
+  (`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
+  accepted network-scale hot path; resource paths are adapter inputs rather than
+  stable content IDs; animation/equipment/effects and scale profiling remain open.
+- Documentation updated: new world-entity-presentation API/input-output/data-flow/
+  lifecycle/sequence/ownership/failure/configuration/migration/diagnostic/source-map
+  spec; world renderer, module registry and `RENDER.md` updated.
+- Integration: accepted in master merge `606770c`; post-merge entity/facade,

+
+## 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,
+  internal-access, manifest, shutdown, scheduler, planner and focus gates passed.

+- 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
+

+  `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

+
+## 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.

+- Branch: `work/sindo-main-codex/m03-m2-animation-playback`
+- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-m2-animation-playback`
+
+## Outcome
+
+Extract deterministic animated M2 playback selection/phase, AnimationPlayer
+mutation and native animator data/start behavior from `StreamingWorldLoader`.
+
+## Non-goals
+
+- Duplicate or attach animated instances/batch roots.
+- Own visibility, shadow, Editor owner or build-job cursor rules.
+- Load/finalize/cache scenes or change animation eligibility.
+- Change candidate priority, phase formula, logging text or visible playback.
+
+## Paths
+
+- Exclusive: `src/render/m2/m2_animation_playback_controller.gd`,
+  `src/tools/verify_m2_animation_playback_controller.gd`,
+  `docs/modules/m2-animation-playback-controller.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`, M2 animated

+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated resources/caches and proprietary corpus
+
+## Contracts and data
+
+- Phase remains `abs(hash("path:index")) % 1000 / 1000.0`.
+- Exact animation-name priority remains ordinary Stand/Idle/Run/Walk, fish
+  Run/Walk/Swim/Stand/Idle/Death, birds Run/Walk/Swim/Stand/Idle, then
+  case-insensitive substring fallback and first-name fallback.
+- Every AnimationPlayer animation becomes linear-looping before selected play;
+  positive-length selection seeks to deterministic phase.
+- Native animators match exact script identity in depth-first order, copy the
+  same five fields, call prepare_runtime when available and set phase.
+- Runtime debug state is sampled only when existing debug mode requests it;
+  loader retains final log formatting/path normalization.
+
+## Dependencies
+
+- Requires: accepted animated scene finalizer package on master `c0a7bfb`
+- Blocks: animated M2 instance materializer extraction
+- External state: AnimationPlayer and M2NativeAnimator APIs remain engine/scene contracts
+
+## Verification
+
+- Commands: dedicated phase/selection/loop/play/seek/native-copy/start/diagnostic/
+  source/timing verifier; animated finalizer/pipeline/prototype/build/shutdown/
+  material/facade/internal-access/manifest regressions; docs/coordination/dry-run gates
+- Fixtures: synthetic AnimationPlayers and real M2NativeAnimator nodes
+- Fidelity evidence: exact priority, phase and mutation/reference contracts
+- Performance budget: 20,000 selection/phase operations under 1 second
+
+## Documentation deliverables
+
+- Inline API docs
+- Module spec with inputs/outputs, ownership and source map
+- Data-flow, lifecycle/state, sequence and dependency diagrams
+- Adjacent finalizer/build/world-renderer/module-registry/RENDER updates
+
+## Simplicity and naming
+
+- Important name introduced: `M2AnimationPlaybackController`
+- Simplest solution: stateless main-thread RefCounted over supplied Nodes/players
+- Rejected complexity: signals, playback state machine, generic animation framework
+- Unavoidable complexity: native and imported AnimationPlayer paths coexist
+- Measured optimization evidence: bounded selection/phase loop
+
+## Status

+- State: accepted
+- Done: playback controller, loader adapters, verifier and required documentation
+- Next: extract animated M2 instance/batch materialization
+- Blocked by:
+
+## Handoff
+
+- Commit: `9b73571`
+- Results: playback controller passes 15 phase/selection/loop/play/seek/native-
+  copy/start/diagnostic/source cases and 20,000 phase-selection pairs in
+  23.415 ms; all 49 autonomous headless verifiers pass, while the proprietary
+  ADT placement probe is unavailable without `data/extracted`; checkpoint
+  dry-run passes 7/7; documentation and coordination gates pass; loader-private
+  inventory remains 30.
+- Remaining risks: private animation-name/timing/native visual comparison,
+  descriptor pressure, leaks and p95/p99 remain unavailable; default selection
+  is still heuristic and no paired original-client comparison is claimed.
+- Documentation updated: inline API; `m2-animation-playback-controller.md` with

+
+## Contracts and data
+
+- One normalized path owns at most one pending request.
+- Pending records preserve Dictionary insertion order for polling snapshots.
+- Terminal completion removes the request and appends its record/status to FIFO.
+- Finalize pop remains oldest-first; duplicate/unknown transitions are rejected.
+- Total work count remains pending plus finalize records.

+- Input: tile-local origin, MMDX name table and raw ADT M2 placement array
+- Output: fresh Dictionary keyed by historically normalized relative M2 path;
+  each value is a fresh ordered Array of tile-local `Transform3D` values
+- Invalid variants, out-of-range name IDs and empty paths are skipped
+- Backslashes become slashes; lowercase `.mdx/.mdl` suffixes become `.m2`
+- Transform basis/origin delegates to `M2PlacementTransformResolver`; final basis
+  scale retains the grouping-path clamp `max(scale, 0.0001)`
+- Cache/schema/coordinate versions: unchanged
+
+## Dependencies
+
+- Requires: current master `c34e538`, `M2PlacementTransformResolver`
+- Blocks: broader M2 worker/build decomposition
+- External state: none; tests use synthetic names and placement dictionaries
+
+## Verification

+- Commands: dedicated invalid/name/path/group-order/default/transform/scale and
+  bounded timing verifier; loader source boundary; resolver/registry/dedupe plus
+  facade/internal-access/manifest/shutdown/documentation/coordination gates
+- Fidelity evidence: exact loop rules and transform composition moved unchanged
+- Performance budget: linear over placement count with fresh output containers;
+  no Node, Resource, RID, task, mutex, cache or file access
+
+## Documentation deliverables
+
+- Inline grouper API documentation
+- New module spec with inputs/outputs, data-flow, lifecycle, ownership, failure,
+  performance, fidelity limitations and source map
+- Transform resolver, renderer/module registry and `RENDER.md` updates

+- Input: ADT-loader Godot Euler rotation, normalized/original M2 relative path,

+- Output: `Basis` and local origin-offset `Vector3`; no retained state
+- Regular models use `Basis.from_euler`; two cliff rocks retain narrow YZX-style

+
+## Contracts and data
+
+- Normalized non-empty paths key static and animated detached `Node3D` prototypes.
+- Missing-model and static-animation outcomes are independent path sets.
+- Exact cached Node reference is returned; first adoption for an occupied path wins.
+- Shutdown frees valid detached nodes synchronously, queues in-tree nodes for free,
+  clears all four states and remains idempotent.
+- Map refresh retains the state exactly as before; only final shutdown clears it.
+
+## Dependencies
+
+- Requires: accepted raw model repository package on master `ca77d32`

+- Commit: `cd664eb`
+- Results: prototype state passes 16 admission/identity/negative/lifecycle/source

+  pass, while the proprietary ADT placement probe is unavailable without

+- Remaining risks: strong prototypes remain unbounded until shutdown; successful

+- Refresh version remains `2`; already-current Meshes return unchanged without raw data.
+- Stale Meshes require caller-supplied raw data only when refresh is necessary.
+- Empty/ordinary raw data marks the original Mesh current and returns it.
+- Billboard/UV-rotation data attempts M2Builder rebuild and returns the rebuilt

+
+- Move tile state, candidate requeue, group/build tasks or result queues.

+
+## 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

+- 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
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,

+  `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.

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

+
+## 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.

+- 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,

+- 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

+
+## 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/

+  world renderer, registry and `RENDER.md` updated.
+- Integration: accepted in master merge `630a0c1`; post-merge cache, facade,

+
+## Outcome
+
+Extract chunk-level terrain LOD desired-state calculation from the streamer into

+
+## Non-goals
+
+- Move chunk/tile queues, loaded state, Mesh/Node/RID creation or budget drains.
+- Change radii, chunk size, threshold inclusivity, priority sorting or tile LOD policy.
+- Normalize/reorder custom radii or reinterpret negative values.

+## Contracts and data
+
+- Input: ADT chunk adapter records, immutable `GodotWorldPosition`, immutable

+## Contracts and data
+
+- Input: resolved WMO placement key and tile/global reference key

+# 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.

 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.

+# 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`.

+
+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

+
+## 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.

+# ADT Water Scene Finalizer
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented extraction |
+| 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
+
+```mermaid

+```
+
+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 | Parsed ADT water-containing Dictionary | ADTLoader/raw tile path | Finalizer/ADTBuilder | Caller retains Dictionary; not mutated | One main-thread call |

+| Input | Valid tile root | StreamingWorldLoader | Finalizer | Caller/SceneTree-owned | Must outlive call and attached subtree |
+| 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.

+  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.

+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.

+| Owners | Gameplay local movement state; scene composition owns the instance |
+| 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.

+## Purpose
+
+Materialize one ordered animated M2 build batch on the main thread. The service
+duplicates an accepted prototype, preserves historical names and transforms,
+applies visibility/shadow settings recursively, starts native/imported playback,
+attaches a non-empty batch and returns detached native diagnostic entries.
+
+## Non-goals
+
+- Plan build batches, advance job cursors or consume render budgets.
+- Load, finalize, select or cache animated prototypes.
+- Select animations or implement native animator deformation.
+- Format logs, normalize paths, assign Editor owners or clean up tile roots.
+- Materialize static M2 `MultiMesh` batches.

+```
+
+## Ownership, threading and resources
+
+- Loader/build state borrows the accepted prototype and ordered transform Array.
+- Each successful duplicate becomes a child of the detached batch immediately.
+- A non-empty batch transfers to the supplied parent; the parent owns its lifetime.
+- A batch with no successful duplicates is queued for deletion and no reference returns.
+- Playback/finalizer services borrow each duplicate only during synchronous calls.
+- Returned diagnostic entries contain the stable instance index and a detached state.
+- All Node duplication, mutation and attachment is main-thread-only.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null parent/prototype | Entry guard | Return `{}` without mutation | Contract verifier | Correct composition/cache state |
+| Empty transforms or non-positive count | Entry guard | Return `{}` | Contract verifier | Planner supplies a non-empty slice |
+| Duplicate is not Node3D | Cast result | Skip that entry and preserve order of successes | Child-count contract | Repair prototype scene root |
+| Every duplicate fails | Empty batch check | Queue empty batch, return `{}` | Empty-result contract | Rebuild/import prototype |
+| Shutdown during/after call | Outside service | Call is synchronous; loader owns cancellation and subtree release | Shutdown regression | Loader cancels job/releases parent |
+
+Transform bounds remain a planner/build-job precondition exactly as before the
+extraction; this service does not clamp or silently reorder an invalid slice.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Duplicate flags | Signals + groups + scripts | All | No | Preserves historical instance behavior |
+| Visibility end/margin | Loader renderer settings / chunk size | All | Yes, between calls | Applied to every GeometryInstance3D descendant |
+| Shadow mode | Loader `m2_cast_shadows` | All | Yes, between calls | Enables/disables descendant shadow casting |
+| Native diagnostics | Loader `debug_streaming` | Debug | Yes | Collects indexed state only when requested |
+
+## Persistence, cache and migration
+
+No data is serialized and no cache/schema version changes. Editor owner
+assignment remains a loader concern after attachment, so generated-scene
+persistence behavior and migration remain unchanged.
+
+## Diagnostics and observability
+
+- The materializer emits no logs, metrics or debug views.
+- Native state remains detached and is tagged with the absolute instance index.
+- Loader preserves the existing normalized-path `M2_NATIVE_ANIMATOR` log text.
+- No correlation ID is introduced; path/index remains the existing identity.
+
+## Verification
+
+- `verify_m2_animated_instance_materializer.gd` covers invalid input, names,
+  order, transforms, recursive visibility/margin/shadows, playback, native field
+  references, indexed diagnostics, prototype immutability and ownership boundaries.
+- Playback/finalizer/pipeline/build/prototype/shutdown/material/facade/internal-
+  access regressions protect adjacent behavior.
+- Fidelity evidence is exact extraction of existing flags/order/settings/calls;
+  no original-client visual comparison or proprietary asset result is claimed.
+- Performance budget: 1,000 synthetic Node3D instances under one second.
+
+## Extension points
+
+A later facade-owned animated presentation command may supply the same explicit
+batch contract. Async SceneTree mutation, callbacks and a generic scene factory
+are intentionally excluded until measurements show a need.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Ordered animated instance/batch materialization | Implemented extraction | Synthetic batch contract verifier | Proprietary asset traversal pending |
+| Recursive visibility/shadow settings | Implemented extraction | Nested geometry fixture | Visual distance/shadow comparison pending |
+| Native/imported playback startup | Delegated to implemented controller | Playback + materializer verifiers | Full WoW animation-state mapping pending |
+| Editor persistence | Existing loader-owned | Source boundary and editor helper | Editor integration fixture remains separate |
+
+## Known gaps and risks
+
+- The existing build planner must continue to guarantee valid transform bounds.
+- Default animation selection and native deformation retain their documented gaps.
+- No private asset, paired original-client, descriptor-pressure, leak or p95/p99 run exists.
+- Recursive render mutation remains proportional to duplicate subtree size.

+```
+
+## Ownership, threading and resources
+
+- Every method runs synchronously on the renderer main thread.
+- A valid candidate is detached and finalizer-owned until acceptance.
+- Acceptance transfers the exact Node3D to the loader/prototype cache path.
+- Rejection frees the candidate synchronously, including wrong-type roots.
+- Traversal results borrow Nodes; source materials remain Resource-owned.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null/unsupported Resource | Type guard | Return null | Dedicated verifier | Loader marks static |
+| Wrong root type | Instantiated type guard | Free and return null | Node-count regression | Rebuild cache |

+| Missing source surface | Material lookup | First source material fallback | Mapping fixture | Repair static source |
+| No AnimationPlayer | Descendant inventory | Free and return empty | Lifetime regression | Loader marks static |
+| Shutdown/cancellation | Not owned | No retained state | N/A | Loader drains first |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Finalize permit | `m2_animation_finalize_ops_per_tick = 1` | Existing profiles | Yes | Caller bounds calls |
+| Material mapping | Depth-first/index-clamped | All | No | Preserves current appearance |
+| Required players | At least one | All | No | Rejects non-animated scenes |
+
+## Persistence, cache and migration
+
+The service retains no state and serializes nothing. GLB/cache formats, material
+versions and prototype lifetimes are unchanged; no rebake is required.
+
+## Diagnostics and observability
+
+- Accepted result reports player count for the existing `M2_ANIM_CACHE` log.
+- Traversal order is deterministic depth-first preorder.
+- The service owns no logging or metrics.
+
+## Verification
+
+- `verify_m2_animated_scene_finalizer.gd` covers invalid Resources, wrong-root
+  release, exact transfer, player traversal/count, override priority, fallback,
+  source-index mapping, source boundaries and timing.
+- Adjacent animation pipeline/prototype/shutdown/material/build tests protect callers.
+- Fidelity evidence is exact mapping/lifecycle extraction; no asset-backed or
+  original-client visual parity claim is made.
+- Performance budget: 10,000 depth-eight player inventories under one second.
+
+## Extension points
+
+Animation playback policy and native animator field copying now belong to
+`M2AnimationPlaybackController`; accepted instance/batch materialization is owned
+by `M2AnimatedInstanceMaterializer`.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| PackedScene candidate | Implemented extraction | Type/lifetime fixture | Proprietary corrupt corpus pending |
+| Material repair | Implemented extraction | Exact-reference mapping | Asset-backed comparison pending |
+| Player validation | Implemented extraction | Nested traversal/transfer | Multi-player GLB corpus pending |
+
+## Known gaps and risks
+
+- Material matching remains positional rather than semantic.
+- Accepted prototypes remain unbounded until final loader shutdown.
+- No private traversal, descriptor-pressure, p95/p99 or paired-client run exists.

+## Purpose
+
+Own cross-frame bookkeeping between a successful animated M2 ResourceLoader
+request, terminal polling and budgeted main-thread scene finalization. This is
+an exact state extraction; animation eligibility and loading remain in
+`StreamingWorldLoader`, while scene finalization and retained Node lifecycle

+
+## Non-goals

+- Select cache paths, interpret ResourceLoader statuses or perform I/O.
+- Decide animated/static fallback or own prototype Nodes.
+- Instantiate PackedScenes, repair materials or consume render permits.

+## Persistence, cache and migration
+
+State is not serialized. Cache formats and prototype lifetimes are unchanged;

+
+## Diagnostics and observability
+
+- `total_work_count()` preserves all three historical `m2_animation` metrics.
+- Snapshots expose only paths and opaque statuses, never Resources or Nodes.
+- Normalized M2 path is the correlation key; existing loader logs are unchanged.
+
+## Verification
+
+- `verify_m2_animation_load_pipeline_state.gd` covers validation, dedupe,

+  source boundaries and 100-by-256 timing.
+- Adjacent renderer, scheduler, prototype and shutdown regressions cover callers.
+- Fidelity evidence is exact state/lifecycle extraction; no visual 3.3.5a parity

+- Performance budget: 25,600 request/complete/pop transitions under one second.
+
+## Extension points
+
+ResourceLoader polling may later move behind a separate adapter without

+
+## Ownership, threading and resources
+
+- Materializer owns prototype duplication, instance/batch roots and SceneTree attachment.
+- Materializer uses finalizer traversal for borrowed AnimationPlayer references.
+- Controller borrows Nodes/Script/players only for the synchronous call.
+- Native arrays are assigned by reference exactly as before extraction.
+- Diagnostic Dictionaries are deep-duplicated before return.
+- Main thread performs all engine-object mutation; pure phase math is thread-safe.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Missing roots/script | Inventory guard | No native copy/start | Contract fixture | Correct composition |
+| Fewer target animators | Pair-count minimum | Copy available pairs only | Native copy fixture | Rebuild import/prototype |
+| No matching name | Ordered fallback | Substring, first name, then empty | Selection fixtures | Add compatible animation |
+| Empty animation selection | Empty result | Skip loop/play/seek for that player | Selection fixture | Static/native path continues |
+| Zero-length selected animation | Length guard | Play without seek | Playback contract | Imported timing remains engine-owned |
+| Cancellation/shutdown | Outside service | No retained state | N/A | Loader owns subtree release |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Phase buckets | 1000 | All | No | Stable per path/index desynchronization |
+| Loop mode | `LOOP_LINEAR` | All | No | Every available imported animation loops |
+| Native diagnostics | `debug_streaming` | Debug | Yes | Samples state only when requested |
+
+## Persistence, cache and migration
+
+No state or format is serialized. GLB/native cache formats, prototype lifetime
+and material versions are unchanged; no rebake is required.
+
+## Diagnostics and observability
+
+- Optional native states remain detached and contain existing prepared,
+  processing, mesh, bone, surface and length fields.
+- Loader retains `M2_NATIVE_ANIMATOR` log formatting and path normalization.
+- Controller emits no logs or metrics.
+
+## Verification
+
+- `verify_m2_animation_playback_controller.gd` covers exact phase, ordinary/
+  fish/bird priorities, substring/first fallback, loop/play/seek, native exact-
+  script order, five-field copy, phase, detached diagnostics and boundaries.
+- Finalizer/build/prototype/material/shutdown regressions protect adjacent behavior.
+- Fidelity evidence is exact policy/mutation extraction; no private asset or
+  original-client animation comparison is claimed.
+- Performance budget: 20,000 phase-and-selection pairs under one second.
+
+## Extension points
+
+Server-driven animation state may later replace default selection through a
+separate presentation contract; this fallback controller must remain available
+for world doodads and compatibility fixtures.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Imported default selection/playback | Implemented extraction | Synthetic priority/play/seek verifier | Asset-backed animation-name corpus pending |
+| Native data/phase startup | Implemented extraction | Exact-reference/native state verifier | Native visual fidelity remains experimental |
+| Instance/batch materialization | Implemented extraction | Materializer contract verifier | Asset-backed traversal pending |
+
+## Known gaps and risks
+
+- Hash phase intentionally depends on existing Godot String hashing behavior.
+- Default-name heuristics are not a complete WoW animation-state mapping.
+- No proprietary traversal, animation timing comparison, p95/p99 or paired-client run exists.

+# M2 Build Batch Planner
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | M03 / `M03-RND-M2-BUILD-BATCH-PLANNER-001` |
+| Owners | Pure static/animated M2 batch sizing and group cursor progression |
+| Last verified | Worktree `work/sindo-main-codex/m03-m2-build-batch-planner`, 2026-07-17 |
+| Profiles/capabilities | Existing static MultiMesh and animated-instance build paths |
+
+## Purpose
+
+Select the effective per-tick M2 batch limit, cap it to remaining transforms and
+plan the next group offset without accessing loader state or renderer resources.
+
+## Non-goals
+
+- Own M2 build jobs, queues, tile state, retries or cancellation.
+- Decide whether an animated prototype or static mesh is ready.
+- Rotate queues or consume `RenderBudgetScheduler` permits.
+- Create or modify Nodes, MultiMesh, Mesh, materials or RIDs.
+- Introduce spatial cells or change profile batch limits.
+
+## Context and boundaries

+
+Allowed dependencies are integer/boolean scalar math and a fresh Dictionary.
+Node, SceneTree, RenderingServer, ResourceLoader, WorkerThreadPool, mutexes,
+renderer caches, gameplay, network, editor UI and files are forbidden.

+    Complete -->|no| Continue[group_complete false; next_offset offset + count]
+```
+
+## 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)
+    Planner-->>Loader: batch_count, next_offset, group_complete
+    Loader->>Loader: resolve/request prototype or mesh
+    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.

+
+## Ownership, threading and resources
+
+- Main thread serializes all state mutation and snapshots.
+- State owns only request/finalize Dictionaries containing Strings and status integers.
+- Loader owns ResourceLoader request lifetime and drains active paths before shutdown clear.
+- `M2MeshResourceCacheState` owns prepared static Mesh references and
+  `M2RuntimeMeshFinalizer` owns refresh/rebuild/fallback. The loader owns shared
+  adoption decisions, raw I/O and remaining engine resources; the prototype
+  cache service owns missing outcomes.
+- Snapshot and diagnostic records are detached; caller mutation cannot affect state.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty/duplicate request | State guard | Reject unchanged | Contract verifier | Correct caller/request later |
+| Request start failure | Loader return code | No state insert; mark missing | Existing loader behavior | Cache/source correction |
+| Non-terminal status | Loader poll | Keep pending | Existing queue metric | Poll next frame |
+| Terminal load failure | Status in popped record | Loader marks missing | Existing missing behavior | World/cache reload |
+| Empty defensive path | Loader before poll | Discard and mark missing | Source regression | Correct request producer |
+| Shutdown | Loader drains pending Resource paths | Clear state | Shutdown verifier | New loader starts empty |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| `m2_mesh_finalize_ops_per_tick` | `1` | Quality/custom | Yes | Bounds terminal FIFO pops outside state |
+| Cache extension order | `.tscn`, `.glb` | Existing M2 path | No | Loader selects request path |
+| Animated pivot-prefix GLB exclusion | Existing rule | All | No | Loader filters before request |
+
+## Persistence, cache and migration
+
+No pipeline state is serialized. M2 cache formats, material refresh version and
+rebuild policy are unchanged; no migration or rebake is required.
+
+## Diagnostics and observability
+
+- `total_work_count` preserves all three historical `m2_mesh` metrics.
+- Diagnostic snapshots expose only paths/statuses, never loaded Resources or Meshes.
+- Existing loader logs and hitch sections remain unchanged.
+- Normalized M2 path is the correlation key.
+
+## Verification
+
+- `verify_m2_mesh_load_pipeline_state.gd`: validation, dedupe, insertion-order
+  polling, terminal transition, completion FIFO, opaque status, discard, metrics,
+  detached diagnostics, loader ownership and 100-by-256 timing.
+- Classifier/material/shutdown/M2 placement/build regressions cover adjacent behavior.
+- Fidelity evidence is exact state/lifecycle extraction; no asset-backed or
+  original-client visual parity claim is made.
+- Performance budget: 25,600 request/complete/pop transitions under one second.
+
+## Extension points
+
+- Mesh/missing cache adoption can move to a separate finalizer without changing this state.
+- Animated M2 has distinct candidate/static fallback semantics and remains separate.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Static M2 request/finalize state | Implemented extraction | Contract/source/timing verifier | Asset-backed long traversal pending |
+| ResourceLoader I/O | Existing loader-owned | Shutdown/material regressions | I/O adapter extraction optional |
+| Mesh cache | Implemented extraction | Mesh resource cache state verifier | Asset-backed memory/leak run pending |
+| First-Mesh extraction | Implemented extraction | Resource/order/lifetime verifier | Asset-backed corrupt-scene fixture pending |
+| Mesh preparation | Implemented extraction | Runtime finalizer transition/rebuild verifier | Asset-backed material comparison pending |
+| Mesh materialization | Existing loader-owned | Renderer/material tests | Further safe extraction pending |
+
+## Known gaps and risks
+
+- Records remain Dictionaries because ResourceLoader polling is a dynamic Godot boundary.
+- Clear does not drain ResourceLoader; caller ordering is mandatory.
+- Status integers are intentionally opaque inside state.
+- No private asset traversal, leak/descriptor-pressure or p95/p99 run is included.

+# M2 Mesh Resource Cache State
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented extraction |
+| Target/work package | M03 / `M03-RND-M2-MESH-RESOURCE-CACHE-001` |
+| Owners | Prepared static M2 Mesh resource references by normalized path |
+| Last verified | Worktree `work/sindo-main-codex/m03-m2-mesh-resource-cache`, 2026-07-17 |
+| Profiles/capabilities | Existing static M2 cached and raw fallback paths |
+
+## Purpose
+
+Own the runtime cache of prepared static M2 `Mesh` references outside
+`StreamingWorldLoader`. Dedicated services extract and prepare each Mesh; the
+loader remains responsible for finding, loading, adopting and materializing it.
+
+## Non-goals
+
+- Own the shared M2 missing-path, prototype or animated-scene caches.
+- Call ResourceLoader/FileAccess or select `.tscn`/`.glb` paths.
+- Extract a Mesh from a Resource or Node.
+- Refresh materials, rebuild Meshes or create MultiMesh instances.
+- Add eviction, persistence, cache versions or quality-profile behavior.
+
+## Context and boundaries

+
+The cache may retain `Mesh` resources and copied normalized-path Strings. It has
+no Node, ResourceLoader, filesystem, worker, scheduler, missing-state, builder,
+gameplay, network or editor dependency.
+
+## Public API
+

+```
+
+## Ownership, threading and resources
+
+- Renderer main-thread adapters serialize every cache operation.
+- The cache owns normalized-path Strings and strong Mesh references.
+- Borrowed Mesh lookups do not transfer ownership or duplicate resources.
+- `M2MeshResourceExtractor` owns first-Mesh selection and temporary PackedScene
+  instances. `M2PrototypeCacheState` owns missing/prototype/animated state; the
+  loader owns MultiMeshes and adoption decisions.
+- The loader drains asynchronous work before the final cache clear.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty path or null Mesh | Cache guard | Reject unchanged | Contract verifier | Correct caller input |
+| Unknown lookup | Membership query | Return null | Existing loader path | Request/load or missing decision |
+| Replacement | Existing key | Retain new exact reference | Contract verifier | Normal subsequent lookup |
+| Load/preparation failure | Loader boundary | Do not store; loader marks missing | Existing renderer behavior | Cache/source correction and reload |
+| Final shutdown | Loader lifecycle | Clear releases references | Shutdown/source verifier | New loader starts empty |
+
+## Configuration and capabilities
+
+The module adds no setting, budget or profile branch. Cache path order, finalize
+permits and batching remain loader-owned; refresh version `2` belongs to
+`M2RuntimeMeshFinalizer`.
+
+## Persistence, cache and migration
+
+The state is runtime-only and serializes nothing. Existing `.tscn`/`.glb`
+formats, import caches and material refresh metadata are unchanged; no migration
+or rebake is required.
+
+## Diagnostics and observability
+
+`mesh_count` and `normalized_paths_snapshot` expose scalar ownership diagnostics
+without Mesh references. Existing renderer metrics/logging are unchanged because
+the historical Mesh cache had no queue contribution or log site.
+
+## Verification
+
+- `verify_m2_mesh_resource_cache_state.gd`: invalid input, exact reference,
+  replacement, lookup, detached path snapshot, idempotent clear, loader source
+  ownership and 100-by-256 bounded timing.
+- Mesh pipeline/classifier/material/shutdown/M2 build/facade regressions cover
+  adjacent behavior.
+- Fidelity evidence is exact cache/lifetime extraction; no original-client
+  visual-parity or asset-backed performance claim is made.
+
+## Extension points
+
+- `M2RuntimeMeshFinalizer` returns a prepared Mesh for `store_mesh` without
+  changing cache ownership.
+- Eviction requires measured memory pressure and explicit lifetime semantics.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Prepared static M2 Mesh cache | Implemented extraction | Contract/source/timing verifier | Asset-backed memory/leak run pending |

+| M2 Mesh extraction | Implemented extraction | Resource/order/lifetime verifier | Asset-backed corrupt-scene fixture pending |
+| M2 Mesh preparation | Implemented extraction | Runtime finalizer transition/rebuild verifier | Asset-backed material comparison pending |
+
+## Known gaps and risks
+
+- Strong Mesh references intentionally remain until final shutdown.
+- Missing/prototype/animated lookup state is now a separate sibling service.
+- No proprietary M2 traversal, leak/descriptor-pressure, p95/p99 or paired

+
+## Purpose
+
+Select the first M2 Mesh from a direct Resource, PackedScene or existing Node
+subtree while keeping traversal and temporary-node lifetime outside
+`StreamingWorldLoader`.
+
+## Non-goals
+
+- Request/load Resources or choose cache paths.
+- Load raw M2 data, refresh materials or rebuild Meshes.
+- Own Mesh/prototype/missing caches or pending/finalize queues.
+- Create MultiMeshes, attach Nodes or consume render permits.
+- Change first-Mesh selection order or visible output.

+
+The extractor may inspect `Resource`, `PackedScene`, `Node`, `MeshInstance3D`

+```
+
+## Ownership, threading and resources
+
+- The renderer main thread performs all traversal and PackedScene instantiation.
+- Direct and subtree Mesh references are borrowed without duplication.
+- A PackedScene temporary root is extractor-owned and synchronously freed.
+- Existing prototype/rebuild subtrees remain caller-owned and are never mutated.
+- Cache retention remains a cache-state concern; runtime material preparation
+  belongs to `M2RuntimeMeshFinalizer`.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null/unsupported Resource | Type guard | Return null | Contract verifier | Loader marks missing/falls back |

+| Null MeshInstance Mesh | Null traversal result | Parent continues with later siblings | Order verifier | Normal sibling search |
+| Shutdown/cancel | No retained state | No action | Ownership docs | Caller owns surrounding job |
+
+## Configuration and capabilities
+
+The module adds no settings or profile branches. Cache format order, material
+refresh version, render permits and batching remain unchanged outside it.
+
+## Persistence, cache and migration
+
+The extractor is stateless and serializes nothing. Existing `.tscn`/`.glb`
+formats, cache versions and rebuild metadata are unchanged; no migration or
+rebake is required.
+
+## Diagnostics and observability
+
+The module emits no logs and retains no counters. Loader correlation remains the
+normalized M2 path. Its verifier measures traversal time and temporary Node count.
+
+## Verification
+
+- `verify_m2_mesh_resource_extractor.gd`: direct/invalid Resources, depth-first
+  child order, null-Mesh sibling continuation, subtree ownership, PackedScene
+  exact Mesh identity, temporary Node release, source boundaries and 10,000
+  bounded traversals.
+- M2 pipeline/cache/classifier/material/shutdown/build regressions cover adjacent
+  behavior. No asset-backed visual parity claim is made.
+
+## Extension points
+
+- `M2RuntimeMeshFinalizer` consumes the Mesh returned here and the loader stores
+  its result in `M2MeshResourceCacheState`.
+- Broader generic scene traversal is intentionally excluded until another real
+  consumer requires the same exact contract.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Direct/PackedScene first-Mesh extraction | Implemented extraction | Resource/order/lifetime verifier | Asset-backed corrupt-scene fixture pending |
+| Prototype/rebuild subtree selection | Implemented extraction | Synthetic preorder verifier | Asset-backed M2 traversal pending |
+| Material refresh/rebuild finalization | Implemented extraction | Runtime finalizer transition/rebuild verifier | Asset-backed material comparison pending |
+
+## Known gaps and risks
+
+- PackedScene instantiation remains synchronous main-thread work behind the
+  existing finalize permit.
+- The first Mesh rule intentionally ignores additional MeshInstances.
+- No proprietary M2 corpus, corrupt cache, leak/descriptor-pressure, p95/p99 or
+  paired original-client capture is included.

+
+## 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.

+
+## 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

+        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.

+# M2 Placement Transform Resolver
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | M03 / `M03-RND-M2-PLACEMENT-TRANSFORM-001` |
+| Owners | Pure ADT M2 placement basis and model-specific origin compensation |
+| Last verified | Worktree `work/sindo-main-codex/m03-m2-placement-transform`, 2026-07-16 |
+| Profiles/capabilities | Existing static M2 paths; four calibrated model exceptions |
+
+## 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.
+
+## Context and boundaries

+
+Allowed dependencies are `Vector3`, `Basis`, scalar math and path-string
+normalization. Node, SceneTree, RenderingServer, ResourceLoader, tasks, caches,
+files, gameplay, network and editor UI are forbidden.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `resolve_basis(rotation_radians, relative_m2_path)` | Pure query | Return unscaled regular or calibrated placement orientation | Worker/main thread; call-local result | Unknown paths use `Basis.from_euler` |
+| `resolve_origin_offset(rotation_radians, relative_m2_path, scale_value)` | Pure query | Compensate the measured tall-waterfall twist anchor | Worker/main thread; call-local result | Regular/unanchored paths return zero; scale clamps to `0.0001` for compensation |
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Godot Euler rotation in radians | ADT loader placement record | Resolver | Scalar copy | One call |
+| Input | Relative M2 path | ADT MMDX/name table | Resolver allowlist | Caller string | One call |
+| Input | Raw placement scale | ADT placement record | Offset compensation | Scalar copy | One call |
+| Output | Unscaled `Basis` | Resolver | Grouper/placeholder/instance adapter | Value copy | One call |
+| Output | Local `Vector3` offset | Resolver | Grouper/placeholder/instance adapter | Value copy | One call |
+
+Callers preserve their historical basis scale minima: grouping/instance use
+`0.0001`, while placeholders use `0.01`.
+
+## Data flow
+
+```mermaid
+flowchart TD
+    BasisCall[resolve_basis] --> ModelName[Normalize separators/case/basename]
+    ModelName --> Waterfall{Waterfall sheet?}
+    Waterfall -->|yes| WaterfallBasis[+90 degree world yaw * Euler * local-axis twist]

+    Anchored -->|yes| Compensation[(base anchor - twisted anchor) * clamped scale]
+```
+
+## 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.

+# M2 Prototype Cache State
+
+## Metadata
+
+| Field | Value |
+|---|---|

+| Profiles/capabilities | Static, GLB animated and native animated M2 prototype reuse |
+
+## Purpose
+
+Own the four shutdown-lifetime M2 prototype lookup states previously stored in
+`StreamingWorldLoader`: static and animated `Node3D` references, missing model
+paths and paths whose animation fallback is static-only.
+
+## Non-goals
+
+- Normalize paths, choose cache files, call ResourceLoader or parse raw M2 data.
+- Build, repair or instantiate prototypes, Meshes, materials or MultiMeshes.
+- Own animation/Mesh request queues, permits or tile/build state.
+- Add eviction, persistence, retries, profile rules or format changes.

+## Data flow

+
+## Ownership, threading and resources
+
+- Renderer main-thread adapters serialize all operations.
+- The state owns strong references to adopted static and animated prototype Nodes.
+- A duplicate detached candidate is released immediately; the first valid Node
+  stays canonical for that path.
+- Lookups borrow exact Node references without transferring ownership.
+- Detached Nodes are synchronously `free()`d at shutdown. Defensive in-tree
+  Nodes use `queue_free()` to preserve SceneTree rules.
+- Negative entries own only copied normalized-path Strings.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty path/null/invalid Node | Admission guard | Reject/null/false | Dedicated verifier | Correct caller input |
+| Unknown positive lookup | Map miss | Return null | Path snapshot | Loader continues existing load/fallback |
+| Duplicate candidate | Occupied valid path | Release candidate; return first | Identity fixture | None required |
+| Model source/load failure | Loader result | Mark missing outcome | Existing fallback behavior | New loader session/source repair |
+| Animation unavailable/unsafe | Loader policy/result | Mark static-only outcome | Existing fallback behavior | New loader session/cache repair |
+| Shutdown | Loader lifecycle | Release positive and clear all state | Shutdown verifier | New loader begins empty |
+| Cancellation | Not owned | No state transition inside this service | N/A | Loader drains/cancels before shutdown clear |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Positive cache lifetime | Final loader shutdown | All | No | Reuses detached prototypes across map refresh |
+| Negative cache lifetime | Final loader shutdown | All | No | Preserves historical fallback suppression |
+| Eviction capacity | Unbounded historical behavior | All | No | No mid-session Node destruction |
+
+Animation enablement, candidate/allow/deny rules, cache paths and per-frame
+permits remain loader configuration.
+
+## Persistence, cache and migration
+
+This is runtime-only state and serializes nothing. `.tscn/.glb`, material refresh
+and native M2 formats are unchanged; no migration or rebake is introduced.
+
+## Diagnostics and observability
+
+- `diagnostic_snapshot` exposes four sorted path arrays without Node references.
+- Existing `M2_ANIM_CACHE` and native animation logs remain loader-owned.
+- Existing renderer queue metrics remain unchanged because these tables never
+  contributed work counts.
+- Normalized relative path remains the correlation key.
+
+## Verification
+
+- `verify_m2_prototype_cache_state.gd`: invalid admission, exact static/animated
+  identity, independent positive/negative states, first-wins duplicate release,
+  detached/in-tree shutdown ownership, idempotent clear, detached diagnostics,
+  loader source boundaries and 100-by-256 bounded path-state timing.
+- Runtime-cache shutdown regression verifies final release through the real loader.
+- Raw repository/finalizer/extractor/Mesh cache/pipeline/material/animation/M2
+  build regressions protect adjacent behavior.
+- Fidelity evidence is exact cache transition and lifetime extraction. No new
+  proprietary asset or original-client visual comparison is claimed.
+
+## Extension points
+
+Eviction or byte/count budgets require measured memory evidence and explicit
+prototype-user lifetime rules. Animation request-state extraction can consume
+this service without moving ResourceLoader or builder ownership into it.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Static prototype retention | Implemented extraction | Identity/source/shutdown verifier | Asset-backed traversal/leak run pending |
+| Animated prototype retention | Implemented extraction | Independent identity/shutdown verifier | Legal animated success fixture pending |
+| Missing/static-only outcomes | Implemented extraction | Independent negative-state verifier | Recovery still requires new loader session |
+| Bounded eviction | Historical unbounded behavior | Documented lifetime | Add only after memory profiling |
+
+## Known gaps and risks
+
+- Strong Node references intentionally live until final shutdown.
+- Negative outcomes do not retain reason codes and cannot be individually retried,
+  preserving historical behavior.
+- No proprietary long traversal, descriptor pressure, leak, p95/p99 or paired
+  original-client evidence is included.

+
+## Purpose
+
+Provide one stateless boundary between renderer orchestration and the optional

+## Non-goals
+
+- Normalize relative paths or choose `.tscn`/`.glb` cache fallbacks.
+- Cache successful data, missing paths, Meshes, Nodes or animation decisions.

+
+## Ownership, threading and resources
+
+- The repository owns only call-local path, native instance and result values.
+- The loader owns path normalization and fallback selection;
+  `M2PrototypeCacheState` owns prototype/negative adoption.
+- Native `M2Loader` owns parsing behavior and returns a new Dictionary value.
+- Calls are synchronous on the caller's thread; current renderer callers use the
+  main thread. The module starts no tasks and touches no SceneTree objects.
+- No file handle, native instance, Dictionary or engine Resource is retained.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Empty normalized path | String guard | Return `{}` | Dedicated verifier | Correct caller normalization |
+| Native extension absent | `ClassDB.class_exists` | Return `{}` | Existing renderer fallback | Install/load extension and retry |
+| Extracted file absent | `FileAccess.file_exists` | Return `{}` | Prototype cache records historical missing state through loader | Restore extraction and start a new loader session |
+| Instance/method absent | Null/`has_method` guard | Return `{}` | Source contract verifier | Repair extension registration |
+| Parse/non-Dictionary result | Result type check | Return `{}` | Existing loader fallback | Repair asset/parser and retry |
+| Cancellation requested | Not supported inside synchronous native call | Call completes | None | Caller controls whether to start call |
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Native class name | `M2Loader` | All | No | Exact GDExtension registration |
+| Static method | `load_m2` | All | No | Existing static parser path |
+| Animated method | `load_m2_animated` | Experimental animated path | No | Existing native animation parser |
+| Extracted directory | Loader `extracted_dir` | Scene configuration | Yes, caller-owned | Root used for path join |
+
+## Persistence, cache and migration
+
+The module adds no persistence or cache. Native methods, normalized relative
+paths and `.tscn/.glb`/material versions are unchanged, so no migration or rebake
+is required.
+
+## Diagnostics and observability
+
+- Logs: none; loader retains existing fallback and debug output.
+- Metrics: none; rejected-input timing is verifier-only.
+- Debug views: none.
+- Correlation ID: normalized relative M2 path in the caller.
+
+## Verification
+
+- `verify_m2_raw_model_repository.gd` covers empty/missing/repeated failures,
+  exact static/animated method ownership, three loader delegations, forbidden
+  dependencies and 10,000 empty-path rejects under one second.
+- Adjacent finalizer/extractor/cache/pipeline/animation/material/shutdown tests
+  protect caller behavior and ownership.
+- Fidelity evidence is structural: exact path join/globalization and native
+  method names are preserved. No proprietary M2 or original-client visual claim
+  is made by this extraction.
+
+## Extension points
+
+Future asset-backed verification may add a legal fixture around these value
+contracts. Caching, asynchronous I/O and parser replacement require separate
+measured work packages rather than expansion of this repository.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Static raw M2 read | Implemented extraction | Source/invalid/missing verifier | Legal success fixture pending |
+| Native animated raw M2 read | Implemented extraction | Exact method/source contract | Legal animated fixture pending |
+| Stateless failure behavior | Verified synthetic | Repeated missing call and source boundary | Asset-backed corrupt input pending |
+
+## Known gaps and risks
+
+- Native parsing remains synchronous and has no mid-call cancellation.
+- The repository deliberately does not distinguish missing dependency, missing
+  file and parser failure; loader fallback behavior historically treats them alike.
+- Proprietary asset traversal, descriptor pressure, p95/p99 and visual comparison
+  remain outside this structural extraction.

+| Last verified | Worktree `work/sindo-main-codex/m03-m2-runtime-mesh-finalizer`, 2026-07-17 |
+| Profiles/capabilities | Static cached and prototype M2 runtime material preparation |
+
+## Purpose
+
+Finalize an extracted static M2 Mesh for runtime use by accepting already-loaded
+raw M2 data, preserving material refresh version `2`, rebuilding only billboard/
+UV-rotation cases and returning the historical original-Mesh fallback.
+
+## Non-goals
+
+- Read raw `.m2` files or call ClassDB/FileAccess/ResourceLoader.
+- Own request/finalize queues, Mesh/missing/prototype caches or MultiMeshes.
+- Select cache paths or extract a Mesh from the originally loaded Resource.
+- Change classifier predicates, builder materials, refresh version or profiles.

+
+The finalizer may use Mesh metadata, raw value Dictionaries, M2Builder and the
+two existing scene-free M2 services. Raw-file I/O, cache state, render permits,
+Nodes outside temporary rebuild roots and other application layers are forbidden.

+```
+
+## Ownership, threading and resources
+
+- Renderer main thread executes metadata changes and M2Builder work.
+- `M2RawModelRepository` owns raw M2 file/native calls; loader supplies its value result.
+- Finalizer owns classifier memoization and temporary rebuild prototype lifetime.
+- M2Builder owns construction rules; extractor selects the first rebuilt Mesh.
+- Cache/prototype adapters decide where the returned Mesh reference is retained.
+
+## Errors, cancellation and recovery
+
+| Failure/state | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null Mesh | Guard | Return null | Contract verifier | Caller marks missing |
+| Current Mesh | Metadata query | Return exact reference; no raw load | Contract verifier | None needed |
+| Raw file/parse unavailable | Empty Dictionary from loader | Mark/reuse original | Existing renderer behavior | Source/cache repair |
+| Ordinary stale Mesh | Classifier false | Mark/reuse original | Classifier verifier | None needed |
+| Builder produces no Mesh | Extractor null | Mark/reuse original | Finalizer fallback fixture | Source/builder repair |
+| Reset/shutdown | Loader lifecycle | Clear classifier decisions | Source/clear verifier | Recompute next session |
+
+## Configuration and capabilities
+
+`MATERIAL_REFRESH_VERSION` remains `2` and is now owned by this finalizer.
+Finalize permits, cache paths, extracted directory configuration and quality
+profiles remain unchanged in the loader.
+
+## Persistence, cache and migration
+
+No new format is serialized. Existing Mesh metadata key
+`wow_m2_material_refresh_version`, M2Builder `MATERIAL_FORMAT_VERSION == 2` and
+`.tscn/.glb` caches are unchanged; no migration or rebake is introduced.
+
+## Diagnostics and observability
+
+`cached_rebuild_decision_count` exposes only a scalar count. Existing renderer
+logs/queue metrics are unchanged. Normalized M2 path remains the correlation key.
+
+## Verification
+
+- `verify_m2_runtime_mesh_finalizer.gd`: null/current/raw requirement, empty and
+  ordinary marking, synthetic triangle billboard rebuild, rebuild failure
+  fallback, refresh metadata, classifier clear, source boundary and 100-by-256
+  bounded finalization.
+- Classifier/extractor/cache/pipeline/material/shutdown/M2 build regressions cover
+  adjacent behavior. No asset-backed or original-client visual claim is made.
+
+## Extension points
+
+- Asset-backed fixture coverage can be added without changing the finalizer's
+  value-data contract.
+- Refresh versions above `2` require explicit cache/fidelity evidence and docs.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Runtime Mesh refresh/fallback | Implemented extraction | Synthetic transition/rebuild verifier | Asset-backed corrupt/stale cache pending |
+| Rebuild predicate | Implemented extraction dependency | Classifier fixtures | Original-client material comparison pending |
+| Raw M2 refresh I/O | Implemented repository dependency | Repository source/invalid verifier | Legal success fixture pending |
+
+## Known gaps and risks
+
+- Required rebuild remains synchronous main-thread work behind existing permits.
+- Synthetic geometry proves transition/build behavior, not full asset materials.
+- No proprietary M2 traversal, descriptor-pressure/leak, p95/p99 or paired
+  original-client capture is included.

+
+## Purpose
+
+Determine whether a stale cached M2 mesh must be rebuilt in memory from raw M2
+data to restore billboard custom attributes or UV-rotation material inputs. The
+first decision is memoized by normalized relative path for the current map/
+runtime-cache lifetime.
+
+## Non-goals
+
+- Read M2 files or invoke `M2Loader`/`M2Builder`.
+- Own cached Meshes, scenes, materials, Nodes or RIDs.
+- Select cache paths, perform ResourceLoader transitions or consume permits.
+- Change refresh/cache format versions or shader behavior.
+- Classify animation, particles, ribbons or general visual fidelity.

+
+## Ownership, threading and resources
+
+- The classifier owns only normalized-path boolean entries.
+- The finalizer owns classifier lifetime, rebuild decisions and refresh metadata.
+- The loader owns raw loading, cache/resource selection and Mesh adoption.
+- 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 |
+| `MATERIAL_REFRESH_VERSION` | Finalizer 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 |
+| Runtime Mesh finalization | Implemented extraction | Finalizer transition/rebuild fixtures | Asset-backed material comparison 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.

+
+## 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.

+| Target/work package | M02 / M02-GMP-INPUT-001, M02-GMP-SANDBOX-CAPABILITIES-001, M02-GMP-INPUT-PROFILE-335-001 |
+| Owners | Gameplay input boundary; `sindo-main-codex` for current package |
+| Last verified | M02-GMP-INPUT-PROFILE-335-001 worktree, 2026-07-15 |
+| Profiles/capabilities | Distinct RenderSandbox and Blizzlike335 action layouts; debug execution remains RenderSandbox-only |
+
+## 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.
+
+## Context and boundaries
+
+```mermaid

+    Intent --> Movement[LocalPlayerMovementController]
+    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 |
+| `MoveIntent.has_translation()` | Query | Reports whether any translation axis is non-zero | Any thread while value remains immutable | None |
+| `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 |
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Movement action strengths | Godot `InputMap`/`Input` | `PlayerInputSource` | Engine-owned snapshot | Sampled on main physics tick |
+| 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.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Engine as Godot Input
+    participant Source as PlayerInputSource
+    participant Intent as MoveIntent
+    participant Move as LocalPlayerMovementController

+    Source-->>Player: sample_move_intent()
+    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
+  private build-12340 `DefaultBindings.wtf`/`Bindings.xml` hashes and selected
+  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.

+- 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.
+
+## Source map
+
+| Path | Responsibility |
+|---|---|
+| `src/render/streaming/render_budget_scheduler.gd` | Scene-free lane counters, permits, diagnostics and cancellation |
+| `src/scenes/streaming/streaming_world_loader.gd` | Limit composition, fixed drain order, queue/resource ownership and operation execution |
+| `src/tools/verify_render_budget_scheduler.gd` | Asset-free behavior, dependency and bounded timing regression |

+# Streaming Target Planner
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | `M03-RND-STREAMING-PLANNER-001` |
+| Owners | Renderer workstream / M03 integrator |
+| Last verified | `e887c3b`, 2026-07-15 |
+| Profiles/capabilities | Runtime and Editor preview ADT target selection; profile values supplied by caller |
+
+## Purpose
+
+Calculate which available ADT tiles are wanted and retained for one typed focus
+without accessing the SceneTree, worker tasks, renderer queues, caches or GPU
+resources. Runtime planning preserves prewarm, hysteresis and boundary-prefetch
+behavior; editor planning preserves the square preview radius.
+
+## Non-goals
+
+- Mutate load/finalize/eviction queues.
+- Prioritize queued tile paths by world distance.
+- Calculate chunk or tile LOD levels after a tile is loaded.
+- Own the available WDT tile catalog or cache paths.
+- Create, cancel or await jobs.
+- Implement M2, WMO, liquid or terrain attachment.

+
+## 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
+    participant Plan as StreamingTargetPlan
+    Stream->>Planner: plan_runtime(catalog, typed focus, policy)
+    Planner->>Mapper: focus tile and tile-local position
+    Mapper-->>Planner: typed coordinates
+    Planner->>Planner: prefetch centers and available key sets
+    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.
