 - 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 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
+
+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

+- 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.

+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Correct the additive coordinate contract so `AdtTileCoordinate(tile_x, tile_y)`
+matches actual `Map_tileX_tileY.adt` filenames and MCNK `indexX/indexY` axes.
+
+## Non-goals
+
+- Migrating renderer/native consumers.
+- Changing canonical, server, Godot or ADT placement position arithmetic.
+- Adding server-spawn fixtures or `StreamingFocus`.
+- Committing proprietary ADT bytes.
+
+## Paths
+
+- Exclusive: `src/domain/coordinates/coordinate_mapper.gd`,
+  `src/domain/coordinates/adt_chunk_coordinate.gd`,

+- Shared/hotspots: `docs/adr/0001-canonical-world-coordinates.md`,

+- Generated/ignored: local extracted ADT and Godot import metadata
+
+## Contracts and data
+
+- Public API/events: method names unchanged; corrected tile/chunk axis semantics
+- Schema/format version: coordinate contract version increments from 1 to 2
+- Migration/compatibility: no released consumer exists; contract was merged but
+  not yet consumed, so correction precedes consumer rollout
+- Consumers: future renderer, network, gameplay and server-data adapters
+
+## Dependencies
+
+- Requires: merged `M01-FND-COORDS-001` at `1c0dfc7`
+- Blocks: coordinate golden fixtures and all coordinate consumers
+- External state: private `Azeroth_31_49.adt` used read-only for evidence
+
+## Verification
+
+- Commands: coordinate mapper probe, M00 calibration, manifest, documentation
+  and coordination gates
+- Fixtures: build 12340 Elwynn point must resolve to `Azeroth_31_49.adt`;
+  MCNK `(0,0)` and `(15,15)` establish chunk-axis direction
+- Fidelity evidence: local ADT SHA-256
+  `18185B5FAC9566D9C57A9C19ABD75F108370D1795639B6077167C0EFD3672FAE`;
+  OpenRealm independently indexes filename X from world Y and filename Y from world X
+- Performance budget: unchanged constant-time scalar arithmetic
+
+## Documentation deliverables
+
+- Inline public API docs: corrected tile/chunk direction comments
+- Module specification: contract version, formulas, capability evidence and risk
+- Data-flow diagram: corrected filename/chunk axes
+- ADR: corrected decision and evidence
+- Sequence/state diagrams: not applicable; pure synchronous mapper
+
+## Simplicity and naming
+
+- Important names introduced: none
+- Simplest considered solution: swap the two filename formulas and corresponding
+  local/chunk ownership calculations
+- Rejected complexity/abstractions: compatibility flag for a contract with no consumers
+- Unavoidable complexity and justification: ADT filename axes differ from client X/Y order
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: raw-corpus diagnosis, filename/local/chunk axis correction, contract
+  version 2 documentation and regression fixtures
+- Next: integrator review and merge before coordinate consumer work
+- Blocked by:
+
+## Handoff
+
+- Commit: `a7072e3`
+- Branch: `work/sindo-main-codex/m01-coordinate-tile-axis-fix`
+- Outcome: `tile_x/chunk_x` now grow east from canonical Y and
+  `tile_y/chunk_y` grow south from canonical X; public method names unchanged
+- Contract/schema: coordinate contract version 2; no persisted format, cache or migration
+- Verification: coordinate mapper PASS (5 build-12340 points, 8 boundaries,
+  2 recorded raw MCNK origins, 5 yaw cases); M00 calibration PASS with maximum
+  error `0.000015`; renderer manifest, coordination, documentation, dependency
+  and whitespace checks passed
+- Fidelity: private `Azeroth_31_49.adt` hash and raw MCNK origins recorded in
+  ADR 0001; OpenRealm independently uses the same filename-axis ordering
+- Rebuild: none; private/generated prerequisites remain outside Git
+- Remaining risks: server spawn fixture, native placement conversion and
+  MDDF/MODF Euler semantics remain subsequent M01 packages
+- Recommended merge order: merge this correction before golden fixture or consumer migration
+- Documentation: ADR 0001 and coordinate-mapping module data flow, contract
+  version, capability evidence and known risks updated

+## Outcome
+
+Introduce scene-free value objects for canonical WoW, server, ADT placement,

+
+## Non-goals

+- Migrating `StreamingWorldLoader`, native parsers, sky, player or renderer code.

+- 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,

+- Fixtures: five build 12340 camera points, ADT map center/edge/boundary points,

+- Module specification: purpose, public API, inputs/outputs, ownership, errors and source map
+- Data-flow diagram: server/ADT/canonical/Godot mappings

+- 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,

+- Unavoidable complexity and justification: distinct source spaces prevent silent axis swaps
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review

+- 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

+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Add scene-free, immutable identity values for stable authored content,

+callers cannot silently interchange their numeric/string representations.
+
+## Non-goals

+
+## 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

+- Lease expires UTC: 2026-07-16
+- 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
+
+- Exclusive: M01/M02 target status, M01 final Evidence and M01 claim acceptance markers

+- Public APIs, schemas, cache formats and migrations: unchanged
+- Coordinate contract remains version 2
+- Fixture schema remains version 1
+- Consumers: milestone sequence and M02 work packages
+
+## Dependencies
+
+- Requires: all seven M01 READY commits integrated through master `c8e99f2`
+- Blocks: M02 activation
+- External state: server-spawn GUI hashes and original-client numeric evidence are recorded; proprietary files remain outside Git
+
+## Verification
+
+- Commands: all M01 domain/fixture/boundary/focus/identity/spawn gates,
+  unified renderer dry-run, coordination/documentation checks and diff hygiene
+- Fidelity evidence: five build-12340 points, raw ADT metadata, pinned
+  AzerothCore spawn and cache-complete GUI marker capture
+- Performance: no runtime change; preserve recorded renderer cold/warm evidence
+
+## Documentation deliverables
+
+- M01 final target Evidence and checklist
+- M01 claim integration-acceptance markers
+- Target index and roadmap transition to M02
+- API/module specifications and diagrams are audited, not changed unless a gap is found
+
+## Simplicity and naming
+
+- Important names introduced: none beyond the closeout work-package ID

+
+## Status
+
+- State: ready-for-review
+- Done: accepted seven M01 packages, reran post-merge gates, recorded complete
+  target Evidence, closed M01 and activated M02
+- Next: merge closeout commit before starting an M02 implementation claim
+- 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.

+<!-- OPENWC_INTEGRATION:ACCEPTED:M01-QAR-SERVER-SPAWN-RENDERER-001:c8e99f2 -->
+
+## Ownership
+
+- Target: M01
+- Program: QAR/RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m01-server-spawn-renderer`
+- Lease expires UTC: 2026-07-15
+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Route the pinned AzerothCore Human Warrior spawn fixture through
+`CoordinateMapper` into the live Eastern Kingdoms renderer and produce
+repeatable headless contract checks plus GUI screenshot evidence at the mapped
+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.
+
+## Paths
+
+- Exclusive: `src/tools/server_spawn_render_manifest.json`,
+  `src/tools/verify_server_spawn_renderer.gd`
+- Shared/hotspots: `src/tools/capture_render_checkpoints.gd`, renderer runner,
+  coordinate/world-renderer module documentation, `RENDER.md`, this claim
+- Generated/ignored: Godot UIDs/import metadata and `user://` PNG/JSON evidence
+
+## Contracts and data
+
+- Fixture schema and coordinate contract version remain unchanged.
+- Additive diagnostic checkpoint metadata may request a renderer-native marker;
+  existing M00 checkpoints remain byte-for-byte compatible.
+- The spawn remains sourced from pinned AzerothCore revision
+  `68fcf0098b16388093989627f37be530fc91f07d`.
+
+## Dependencies
+
+- Requires: merged M01 packages through `a07a487`
+- Blocks: M01 golden server-spawn renderer criterion and milestone closeout
+- External state: GUI capture requires the existing local extracted/cached
+  renderer corpus; headless contract verification remains non-proprietary
+
+## Verification
+
+- Commands: dedicated spawn verifier, coordinate fixture/mapper/boundary gates,
+  renderer baseline dry-run, GUI checkpoint capture and human inspection
+- Fixture: AzerothCore race `1`, class `1`, map `0`, server position
+  `(-8949.95, -132.493, 83.5312)`
+- Expected renderer result: Godot position
+  `(17199.159666667, 83.5312, 26016.616666667)`, ADT `(32,48)`, MCNK `(3,12)`
+- Fidelity classification: server/coordinate integration evidence only; it does
+  not establish full original-client visual parity
+
+## Documentation deliverables
+
+- Inline API/tool documentation for new verifier and marker metadata
+- Coordinate-mapping module capability/evidence update
+- World-renderer checkpoint input/output/source-map update when marker support is added
+- Existing synchronous coordinate data-flow diagram updated only if flow changes
+
+## Simplicity and naming
+
+- Important names: `server_spawn_render_manifest`,
+  `verify_server_spawn_renderer`, `diagnostic_spawn_marker`
+- Simplest approach: reuse the existing checkpoint capture pipeline with one
+  dedicated manifest and a renderer-native diagnostic marker
+- Rejected complexity: live DB adapter, new scene-test framework and production
+  spawn entity implementation before the network/gameplay milestones
+- Performance: one diagnostic checkpoint outside production runtime
+
+## Status
+
+- State: ready-for-review
+- Done: fixture-to-renderer manifest/verifier, renderer-native marker, unified
+  baseline integration, cold/warm GUI evidence, documentation and log cleanup
+- Next: integrator review, merge cleanup/handoff and M01 closeout audit
+- Blocked by:
+
+## Handoff
+
+- Commits: implementation `24ddc99`; required cleanup `318e6ae`
+- Branch: `work/sindo-main-codex/m01-server-spawn-renderer`
+- Outcome: the pinned AzerothCore Human Warrior start is routed through
+  `CoordinateMapper` into the ordinary Eastern Kingdoms capture scene. A
+  depth-tested magenta marker begins at the exact mapped spawn origin.
+- Contract/schema: additive diagnostic manifest schema 1 and marker metadata;
+  coordinate contract version 2, production renderer APIs, cache formats and
+  `Blizzlike335` behavior are unchanged.
+- Verification: `SERVER_SPAWN_RENDERER PASS spawn=1 checkpoint=1 tile=32_48
+  chunk=3_12 profile=Blizzlike335`; unified renderer dry-run passed project,
+  materials, M2 dedupe, shutdown, `7/7/7` manifest, five-point calibration,
+  coordinate-boundary and server-spawn steps; coordinate golden fixtures,
+  mapper, StreamingFocus, domain identities, documentation and whitespace gates
+  passed. Coordination passed with five expired M00-claim warnings only.
+- GUI evidence: two `1280x900` cold/warm PNGs captured under
+  `user://server_spawn_renderer_m01_gui_run2`; focus tile `(32,48)`, terrain
+  quality `100/100`, missing cache `0`, queues drained, report results `2`.
+  Human inspection confirms the marker is on rendered terrain beside the road
+  at Northshire Abbey rather than below terrain or in an adjacent tile. PNG
+  hashes: cold `c08c43bcb75e5b3277105afb0d4e5a76caae9db91a7db64488770ffa03e32589`,
+  warm `1b75237a090ea163836372a8e39e778c909773f4508063adc3f70a3e12a85a62`.
+- 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`.

+- 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

+- Public API: immutable `MoveIntent`; `PlayerInputSource.sample_move_intent`

+- Persistence/schema/cache: unchanged
+- Consumers: current sandbox player controller; later local movement controller
+
+## Dependencies
+
+- Requires: merged M01 coordinate/streaming-focus contracts on master `62eece9`
+- Blocks: later M02 movement-controller extraction
+- External state: none; tests use synthetic Input Map events
+
+## Verification
+
+- Commands: dedicated player-input verifier, headless project load, coordinate
+  boundary gate, coordination/documentation gates and diff hygiene
+- Fixtures: synthetic action strengths and configured default bindings
+- Fidelity evidence: current W/S/A/D, Shift, E/Q and Space sandbox behavior remains

+- Performance budget: one immutable intent allocation per physics tick; no I/O

+- Rejected complexity: input provider hierarchy, event bus and generic command framework
+- Unavoidable complexity: none
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: twelve remappable actions, immutable `MoveIntent`, stateless
+  `PlayerInputSource`, controller migration, asset-free regression scene,
+  dedicated verifier and module specification
+- Next: M02 integrator reviews and merges before local movement extraction
+- 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
+

+- 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.

+
+## 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`

+  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.

+- Add jump/fall/swim, server prediction or reconciliation.
+- Change current movement speeds, acceleration, camera-relative flight or ground snap.
+- Gate debug movement by build profile; that remains a separate M02 package.
+- Mark M02 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/gameplay/movement/`,
+  `src/tools/verify_local_player_movement.gd`,
+  `docs/modules/local-player-movement.md`, this claim
+- Shared/hotspots: `src/scenes/player/third_person_wow_controller.gd`,
+  `src/tools/verify_player_input.gd`, `docs/modules/player-input.md`,
+  `docs/modules/README.md`
+- Generated/ignored: local `.godot`, native DLL, generated ADT resources and renderer corpus
+
+## Contracts and data
+
+- Public API: stateful `LocalPlayerMovementController`
+- Inputs: immutable `MoveIntent`, local Godot movement basis and physics delta seconds
+- Outputs: local Godot displacement and read-only velocity/flight state
+- Schema/cache/coordinate contracts: unchanged
+- Consumer: current sandbox player scene; later gameplay composition root
+
+## Dependencies
+
+- Requires: merged input seam on master `14dead1`
+- Blocks: terrain query and camera/presentation extraction from the player hotspot
+- External state: none; unit tests use synthetic intents and bases
+
+## Verification
+
+- Commands: dedicated pure movement verifier, player-input regression, asset-free
+  scene smoke, coordinate/StreamingFocus gates, renderer dry-run and repository gates
+- Fixtures: identity/rotated/pitched bases, acceleration steps, sprint and flight transitions
+- Fidelity evidence: exact current 7.0/4.5/4.5 speeds, 28.0 acceleration,
+  6x sandbox sprint and camera-relative free flight are regression-locked only
+- Performance budget: one small state update per physics tick; no allocation, I/O or scene lookup
+
+## Documentation deliverables
+
+- Inline public API docs for movement state/configuration and update methods
+- Local movement module specification with data-flow, state and sequence diagrams
+- Updated player-input consumer diagram/status and module registry
+
+## Simplicity and naming
+
+- Important name: `LocalPlayerMovementController`
+- Simplest approach: one stateful RefCounted owning velocity and flight toggle
+- Rejected complexity: generic locomotion framework, ECS component hierarchy and event bus
+- Unavoidable complexity: movement basis remains an explicit local-space input
+  so the pure controller does not discover player/camera Nodes
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review
+- Done: scene-free movement state/controller, player scene migration, twelve
+  numeric cases, two flight transitions, integrated regression and module documentation
+- Next: M02 integrator reviews and merges before TerrainQuery extraction
+- Blocked by:
+
+## Handoff
+
+- Commit: `435e1c9`
+- Branch: `work/sindo-main-codex/m02-local-movement`
+- Outcome: `ThirdPersonWowController` no longer owns velocity, flight state,
+  acceleration or directional speed calculation. It selects an explicit
+  Godot-world basis, applies returned displacement, and retains terrain and
+  presentation adapters for later M02 packages.
+- Public contract: additive `LocalPlayerMovementController` with read-only
+  Godot-world velocity/flight state, `toggle_sandbox_flight` and `advance`.
+  Input, coordinate, cache and renderer contracts remain unchanged.
+- Verification: `LOCAL_PLAYER_MOVEMENT PASS cases=12 state_transitions=2
+  scene_boundary=1`; `PLAYER_INPUT PASS actions=12 intent_cases=6 controller=1
+  regression_scene=1`; asset-free scene smoke exited `0`; coordinate boundary
+  and StreamingFocus passed; renderer dry-run passed all eight pre-capture gates
+  and seven checkpoint plans; coordination/documentation/diff gates passed.
+- Fidelity: exact existing defaults are regression-locked—forward `7.0`,
+  backward/strafe `4.5`, acceleration `28.0`, sandbox sprint `6x`, vertical
+  flight `7.0`, velocity reset on toggle and camera-relative pitched flight.
+  This preserves the sandbox baseline but is not original-client evidence.
+- Local verification inputs: the isolated worktree reused the existing ignored
+  native DLL and generated ADT resource scripts. Proprietary extracted data and
+  character GLB were absent, so renderer dry-run logged expected missing-corpus
+  diagnostics while every contract step returned success.
+- Rebuild/migration: none; transient movement state is not persisted.
+- Remaining risks: exported speed changes after `_ready` do not reconfigure the
+  controller; exact build-12340 movement semantics, terrain/collision state,
+  jump/fall/swim, server prediction and debug profile gating remain open.
+- Documentation: inline public API plus `docs/modules/local-player-movement.md`
+  with inputs/outputs, data-flow, state and sequence diagrams, ownership,
+  recovery, capability status, risks and source map; player-input consumer
+  diagrams/status were updated.

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

+
+## 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.

+
+## Dependencies

+- Fixtures: synthetic 145-height chunk payload and injected flat terrain query

+- 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

+- Rebuild/migration: none; caches are transient and existing formats remain unchanged.

+
+## 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.

+- Enable a new collision/raycast behavior before build-12340 comparison.
+- Change initial yaw/pitch, zoom limits, sensitivity, FOV, far plane or camera path.

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

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

+- Unavoidable complexity: rig mutates Camera3D/character Node transforms on main thread
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: ready-for-review

+
+## 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

+# M02-RND-CHARACTER-PRESENTATION-001 — Character presentation boundary
+
+<!-- OPENWC_CLAIM:M02-RND-CHARACTER-PRESENTATION-001:sindo-main-codex:2026-07-16 -->
+
+## Ownership
+
+- Target: M02
+- Program: RND/GMP
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m02-character-presentation`
+- Lease expires UTC: 2026-07-16
+- Integrator: M02 milestone integrator
+
+## Outcome
+
+Move character GLB composition, geoset/texture/outfit setup and locomotion
+animation selection from `ThirdPersonWowController` into independently
+replaceable `CharacterAppearancePresenter` and `CharacterAnimationPresenter`
+components without changing the current sandbox presentation.
+
+## Non-goals
+
+- Add new model, equipment, animation or build-12340 behavior.
+- Change character asset formats, DBC parsing, texture composition or geoset rules.
+- Add network-driven appearance/movement snapshots.
+- Change input, movement, terrain, camera or renderer streaming behavior.
+- Mark M02 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/scenes/character/character_appearance_presenter.gd`,
+  `src/scenes/character/character_animation_presenter.gd`,
+  `src/tools/verify_character_presentation.gd`,
+  `docs/modules/character-presentation.md`, this claim
+- Shared/hotspots: `src/scenes/player/third_person_wow_controller.gd`, runtime
+  streaming scenes, player regression scene, `src/tools/verify_player_input.gd`,
+  `docs/modules/local-player-movement.md`, `docs/modules/README.md`
+- Reused unchanged: geoset controller, texture compositor and outfit resolver
+- Generated/ignored: local `.godot`, native DLL, generated resources and renderer corpus
+
+## Contracts and data
+
+- Appearance API loads/replaces one character root under the existing `Visual` node.
+- Animation API binds an `AnimationPlayer` from that root and accepts a typed
+  moving/stationary presentation state.
+- Scene paths, model defaults, DBC/cache/coordinate contracts remain unchanged.
+- Consumers: player scene composition and renderer viewport only.
+
+## Dependencies
+
+- Requires: merged camera package on master `68e6f60`.
+- Blocks: final M02 sandbox-profile gate and target integration audit.
+- External state: asset-free tests use a synthetic mesh and AnimationPlayer.
+
+## Verification
+
+- Dedicated appearance composition, replacement, grounding and failure regression.
+- Dedicated animation discovery, fallback, looping, blend and state regression.
+- Player source-boundary and three-scene wiring checks.
+- Existing input/movement/terrain/camera regressions, coordinate gates and renderer dry-run.
+- Fidelity evidence: preserve current sandbox model path, scale, yaw, outfit,
+  Stand/Idle and Run/Walk selection only; no original-client parity claim.
+
+## Documentation deliverables
+
+- Inline public API/export documentation for both presenters.
+- Module specification with inputs/outputs, data-flow, lifecycle/state and sequence diagrams.
+- Updated movement consumer/source map and module registry.
+
+## Simplicity and naming
+
+- Important names: `CharacterAppearancePresenter`, `CharacterAnimationPresenter`.
+- Simplest approach: two small scene components on the existing `Visual` subtree.
+- Rejected complexity: generic presenter framework, async asset scheduler and duplicated character systems.
+- Unavoidable complexity: scene-tree composition and AnimationPlayer discovery run on the main thread.
+- Measured optimization evidence: not applicable.
+
+## Status
+
+- State: ready-for-review
+- Done: extracted both presenters, migrated all runtime/regression scenes,
+  added asset-free regressions and completed required module documentation
+- Next: milestone integrator reviews and merges `97bb53f`
+- Blocked by:
+
+<!-- OPENWC_HANDOFF:READY:M02-RND-CHARACTER-PRESENTATION-001:97bb53f -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M02-RND-CHARACTER-PRESENTATION-001:8c71e46 -->
+
+## 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.

+# M03-RND-FACADE-001 — Renderer facade first seam
+
+<!-- OPENWC_CLAIM:M03-RND-FACADE-001:sindo-main-codex:2026-07-17 -->

+## 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.

+- Branch: `work/sindo-main-codex/m03-facade-entity`
+- 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
+
+- Exclusive: `src/render/entities/entity_presentation_snapshot.gd`,
+  `src/render/entities/world_entity_presenter.gd`,

+  scenes, `src/tools/verify_world_render_facade.gd`, `docs/modules/world-renderer.md`,
+  `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,

+
+## Dependencies
+
+- Requires: integrated M03 facade/ground-query master `cb103e1`

+
+## Verification
+
+- Commands: dedicated cold snapshot contract, facade delegation/wiring regression,

+- Fixtures: normalization, non-finite rejection, missing/wrong controller,
+  exact snapshot delegation and existing runtime scene wiring
+- Fidelity evidence: preserve existing fixed-time application and all DBC-derived

+
+## Documentation deliverables
+
+- Inline public API docs: snapshot, facade adapter and sky-controller application
+- Module specification: update existing world-renderer specification
+- Data-flow diagram: snapshot producer through facade into DBC sky controller
+- Sequence/state/dependency diagrams: application/failure path and ownership notes
+- Source map/status updates: world-renderer module, module registry if needed, `RENDER.md`
+
+## Simplicity and naming
+
+- Important names introduced: `WorldEnvironmentSnapshot`, `apply_environment_snapshot`
+- Simplest considered solution: one immutable time snapshot over the existing sky implementation
+- Rejected complexity/abstractions: generic weather graph, duplicated lighting DTO,

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

+- Integration: accepted in master merge `c69abd6`; post-merge snapshot, facade,

+
+## Outcome
+
+Expose typed ground-height sampling and a detached readiness diagnostic through

+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.

+- 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

+
+## 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,

+
+## 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.

+
+<!-- OPENWC_CLAIM:M03-RND-INTERNAL-ACCESS-GATE-001:sindo-main-codex:2026-07-18 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- 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.

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

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

+
+## 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

+
+## Dependencies
+
+- Requires: current master `57ae1b8`

+- Commands: dedicated unkeyed/duplicate/cross-tile/release/clear/detached-
+  diagnostic and bounded timing verifier; loader source boundary; M2 unique-id
+  smoke plus facade/terrain/internal-access/manifest/shutdown/scheduler gates
+- Fidelity evidence: exact positive-ID key format and first-owner/retry behavior
+- Performance budget: dictionary membership over placement count; no Node,
+  Resource, RID, task, file or persistent cache
+
+## Documentation deliverables
+
+- Inline registry API documentation
+- New module spec with inputs/outputs, data-flow, lifecycle, sequence, ownership,
+  failure, recovery, performance and source map
+- World renderer/module registry/`RENDER.md` updates
+
+## Simplicity and naming
+
+- Important name: `M2UniquePlacementRegistry`
+- Simplest solution: one private key-to-owner dictionary and explicit operations
+- Rejected complexity: generic identity registry, signals, callbacks, Resources,
+  locks or ownership graph
+- Unavoidable complexity: raw placement dictionaries remain at ADT adapter boundary
+- Measured optimization evidence: bounded synthetic reserve/release verifier

+- 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.
+

+- 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`

+
+## 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

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

+`TerrainQualityMeshCache`, preserving all call sites and observable behavior.
+
+## Non-goals
+
+- Move ADT parsing, tile state, quality-upgrade tasks/results or SceneTree/RID finalization.
+- Change cache capacity defaults, quality profiles, source priority or cache formats.
+- Cache control-splat/splat meshes that the current loader deliberately rejects.

+
+## 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`

+- Fidelity evidence: same sources/capacity/call sites; all seven baseline plans unchanged
+- Performance budget: dictionary lookup plus bounded single-entry LRU operations;
+  no Node, task, file, cache serialization or RID creation
+
+## Documentation deliverables
+
+- Inline public API docs: store/restore/clear/diagnostics and ownership
+- Module specification: new terrain quality mesh cache specification
+- Data-flow diagram: upgrade result through cache to revisit state
+- Sequence/state/dependency diagrams: store/restore/evict/reset and failure paths
+- Source map/status updates: module registry, world renderer and `RENDER.md`
+
+## Simplicity and naming
+
+- Important names introduced: `TerrainQualityMeshCache`
+- Simplest considered solution: one RefCounted with dictionary plus ordered tile-key array
+- Rejected complexity/abstractions: generic cache framework, weak references,
+  callbacks, Resource cache integration, background eviction or persistence
+- Unavoidable complexity and justification: Mesh references must survive unloaded
+  tile state while LRU keeps revisit memory bounded
+- Measured optimization evidence: exact ownership extraction, no optimization claim

+# 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`.

+# Character Presentation
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented boundary / Partial fidelity |
+| Target/work package | M02 / M02-RND-CHARACTER-PRESENTATION-001 |
+| Owners | Character appearance composition and locomotion animation presentation |
+| Last verified | `97bb53f`, 2026-07-14 |
+| Profiles/capabilities | Current render sandbox character experiment |
+
+## Purpose
+
+Compose the current sandbox character GLB, geosets, skin textures and starter
+outfit below the existing `Visual` node, then independently present its
+stationary or moving animation. Keep visual asset loading and AnimationPlayer
+state out of gameplay movement and the player scene composition root.
+
+## Non-goals
+
+- Define authoritative character identity, equipment or movement state.
+- Change the existing GLB, geoset, texture-compositor, DBC or outfit formats.
+- Implement full build-12340 animation selection, blending or equipment visuals.
+- Load world assets, query terrain, process input or control the camera.
+- Introduce asynchronous streaming, background scene mutation or persistence.
+
+## Context and boundaries

+|---|---|---|---|---|---|
+| Input | Model resource path, class, scale and yaw | Runtime scene composition | Appearance presenter | Exported configuration | Captured at load |
+| Input | Extracted content root | Player scene configuration | Appearance presenter | Copied string | Captured at load |
+| Input | Packed character scene | Godot resource loader | Appearance presenter | Shared resource; presenter owns instance | Scene lifetime |

+        Stationary --> Unbound: bind missing player
+        Moving --> Unbound: bind missing player
+    }
+```
+
+Appearance replacement removes the old root from the scene immediately and
+queues it for deletion. Deferred completion checks root identity, so a stale
+completion cannot publish a replaced model.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Scene as ThirdPersonWowController
+    participant Appearance as CharacterAppearancePresenter
+    participant Existing as Geoset/Compositor/Outfit
+    participant Animation as CharacterAnimationPresenter
+    participant Player as AnimationPlayer
+    Scene->>Appearance: load_character_appearance(content root)
+    Appearance->>Appearance: load, instantiate and attach root

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

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

+# Domain Identities
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | `M01-FND-DOMAIN-IDENTITIES-001` |
+| Owners | Foundation/domain |
+| Last verified | Worktree `work/sindo-main-codex/m01-domain-identities`, 2026-07-13 |
+| Profiles/capabilities | All profiles; identity contract version 1 |
+
+## Purpose
+
+Provide non-interchangeable, scene-free identity values for authored content,
+runtime entities, WoW wire objects and namespaced server entries. Each value
+states its lifetime and serialization rules instead of exposing a generic `id`.
+
+## Non-goals
+
+- Allocating, reserving or globally registering IDs.
+- Parsing packet bytes or server database rows.
+- Mapping GUID high types or server entries to gameplay object kinds.
+- Defining Content Project, snapshot or replay schemas.
+- Replacing future typed map/spell/item/quest/display/sound IDs.
+
+## Context and boundaries
+
+```mermaid
+flowchart LR
+    Authoring[Content Project allocator] --> ContentId[ContentId]
+    Session[Entity registry] --> EntityId[EntityId]

+```
+
+Allowed dependencies:
+
+- GDScript scalar/string operations and `RefCounted` lifetime;
+- callers in content, gameplay, network and server adapter layers.
+
+Forbidden dependencies:
+
+- Node, Resource, SceneTree, renderer and UI state;
+- packet buffers, SQL connections or database table implementations;
+- implicit conversion between identity namespaces;
+- random/global allocation inside the value objects.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `ContentId` | Immutable value | Stable authored identity as canonical lowercase UUID text | Any thread; persisted content lifetime | `is_valid()` reports malformed shape |
+| `ContentId.equals` | Pure method | Value equality across references | Call duration | Null compares false |
+| `ContentId.to_key` | Pure method | Canonical serialization/dictionary key | Stable across schema lifetime | Caller must validate first |
+| `EntityId` | Immutable value | Positive session-local runtime sequence | One runtime session | `is_valid()` rejects zero/negative |
+| `EntityId.equals` | Pure method | Equality within an explicitly shared session | Call duration | Cross-session comparison is a caller error |
+| `EntityId.to_debug_key` | Pure method | Non-persistent diagnostic label | Session/log lifetime | Must not be serialized as content |
+| `WowGuid` | Immutable value | Opaque unsigned high/low wire words | Packet/replay/entity mapping lifetime | `has_valid_word_ranges()` reports overflow |
+| `WowGuid.is_empty` | Pure method | Detect all-zero wire sentinel | Call duration | Does not assign semantic meaning |
+| `WowGuid.to_hex_string` | Pure method | Sixteen-digit diagnostic/replay key | Wire/replay lifetime | Caller validates ranges first |
+| `ServerEntryId` | Immutable value | Adapter/table namespace plus positive entry | Snapshot/deployment mapping lifetime | `is_valid()` rejects missing namespace/non-positive entry |
+| `ServerEntryId.to_key` | Pure method | Namespaced mapping key | Snapshot/schema lifetime | Caller validates first |
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | UUID text | Future Content Project allocator/parser | `ContentId` | Copied normalized string | Build/content lifetime |
+| Input | Session sequence | Future entity registry | `EntityId` | Copied integer | One runtime session |
+| Input | Two unsigned 32-bit words | Future build-12340 packet codec | `WowGuid` | Copied integers | Packet/replay/entity lifetime |
+| Input | Namespace and numeric entry | Future core snapshot adapter | `ServerEntryId` | Copied normalized string/integer | Snapshot/deployment lifetime |
+| Output | Validation/equality/key results | Identity values | Adapters/registries/schemas | Returned scalar/string | Call duration |
+
+Side effects:
+
+- none;
+- no allocation registry, random generation, file/cache write, packet read,
+  database query, scene mutation or logging.
+
+## Data flow
+
+```mermaid
+flowchart TD
+    ContentSource[Authored document] -->|UUID text| ContentId
+    ServerRow[Backend table row] -->|adapter + table + entry| ServerEntryId
+    Packet[World packet] -->|high/low wire words| WowGuid
+    Registry[Session entity allocator] -->|positive sequence| EntityId
+    ServerEntryId --> DeployMap[Explicit deployment mapping]
+    ContentId --> DeployMap
+    WowGuid --> RuntimeMap[Explicit runtime mapping]
+    EntityId --> RuntimeMap
+    DeployMap --> Snapshot[Versioned snapshot/change set]
+    RuntimeMap --> WorldState[Session world state]
+```
+
+## Lifecycle/state
+
+```mermaid
+stateDiagram-v2
+    state ContentIdentity {
+        [*] --> Parsed
+        Parsed --> Persisted: valid ContentId
+        Persisted --> Referenced
+    }
+    state RuntimeIdentity {
+        [*] --> Allocated
+        Allocated --> Active
+        Active --> Released: session owner removes entity
+        Released --> [*]

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

+## Metadata

+|---|---|
+| Status | Implemented |
+| Target/work package | M02 / M02-GMP-MOVEMENT-001, M02-GMP-SANDBOX-CAPABILITIES-001, M02-GMP-INPUT-PROFILE-335-001 and presentation consumers |
+| 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 |

+| 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.

+- 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.

+| Last verified | Worktree `work/sindo-main-codex/m03-m2-unique-registry`, 2026-07-16 |
+| Profiles/capabilities | Existing static M2 placement path; session-memory only |
+
+## Purpose
+
+Ensure a positive ADT `MDDF.uniqueId` has at most one owning streamed tile while
+allowing unkeyed placements through and returning skipped keys for loader-driven
+candidate retry after the owner unloads.
+
+## Non-goals
+
+- Own tile state, retry queues, worker/group/build jobs or detail radius rules.
+- Group placements or create MultiMesh, Mesh, Node, material or RID resources.
+- Validate M2 paths, transforms, animation, materials or build-12340 fidelity.
+- Persist reservations or define a generic identity/ownership framework.
+- Change cache formats, quality profiles or placement visibility.

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

+| 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.
+

+    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

+    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.

+## Metadata

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

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

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

+- Calculate chunk or tile LOD levels after a tile is loaded.
+- Own the available WDT tile catalog or cache paths.

+
+## 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 Planner as StreamingTargetPlanner

+    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.

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

+# Terrain Chunk LOD Planner
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented extraction |
+| Target/work package | M03 / `M03-RND-TERRAIN-LOD-PLANNER-001` |
+| Owners | Pure desired chunk-LOD calculation only |
+| Last verified | Worktree `work/sindo-main-codex/m03-terrain-chunk-lod-planner`, 2026-07-16 |
+| Profiles/capabilities | Existing Performance/Balanced/High/Custom radii |
+
+## Purpose
+
+Calculate the desired terrain LOD for each populated parsed ADT chunk from one
+typed Godot-space focus and one immutable renderer-policy snapshot.
+
+## Non-goals
+
+- Own tile/chunk state, queues, budgets, tasks, Mesh, Node, material or RID.
+- Select tile LOD, create/remove geometry or apply a completed plan.
+- Normalize custom radii, change profile defaults or claim visual parity.
+- Parse ADT data or convert between WoW and Godot coordinate spaces.
+
+## Context and boundaries
+
+```mermaid
+flowchart LR
+    Focus[GodotWorldPosition] --> Planner[TerrainChunkLodPlanner]
+    Chunks[Parsed ADT chunk records] --> Planner
+    Config[Streamer LOD configuration] --> Policy[TerrainChunkLodPolicy]
+    Policy --> Planner
+    Planner --> Desired[chunk index to LOD 0/1/2]
+    Desired --> Loader[StreamingWorldLoader state adapter]
+    Loader --> Queue[Existing create/remove queues and budgets]
+```
+
+Allowed dependencies are the typed Godot position, immutable policy and
+call-local Array/Dictionary/Vector3 values. SceneTree, RenderingServer, gameplay,
+network, files, tasks and persistent caches are forbidden.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `TerrainChunkLodPolicy.new(...)` | Immutable value | Snapshot enabled flag, three raw radii and chunk size | Caller-owned; one planning refresh | Values are preserved without normalization |
+| `TerrainChunkLodPlanner.plan(chunks, focus_position, policy)` | Pure query | Map populated source indices to LOD 0/1/2 | Synchronous; result caller-owned | Invalid/null typed inputs or disabled policy return empty |
+
+The planner validates scripts by preloaded identity so it works from a cold
+Godot global-class cache.
+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Parsed chunk array with `origin: Vector3` | ADT load result | Planner | Loader-owned; read only | One call |
+| Input | `GodotWorldPosition` | Streamer focus adapter | Planner | Immutable caller reference | One call |
+| Input | `TerrainChunkLodPolicy` | Streamer exported configuration | Planner | Immutable caller reference | One call |
+| Output | `{source_chunk_index: 0/1/2}` | Planner | Loader desired state | Fresh caller dictionary | One call |
+
+The Y coordinate is intentionally ignored. Empty chunk records and chunks beyond
+the third radius are absent from the result.
+
+## Data flow
+
+```mermaid
+flowchart TD
+    Start[plan] --> Valid{Typed inputs and enabled?}
+    Valid -->|no| Empty[Return empty dictionary]
+    Valid -->|yes| Radii[Square raw radius times chunk size]
+    Radii --> Iterate[Visit source chunk indices in order]
+    Iterate --> Populated{Record populated?}
+    Populated -->|no| Iterate
+    Populated -->|yes| Center[origin XZ plus half chunk]
+    Center --> Distance[Squared horizontal distance]
+    Distance --> Threshold{First inclusive threshold}
+    Threshold -->|LOD0/1/2| Record[Record source index]
+    Threshold -->|outside| Iterate
+    Record --> Iterate
+    Iterate --> Done[Return desired mapping]
+```
+
+## Lifecycle/state
+
+The planner is stateless. A policy is constructed for one refresh, read during
+synchronous planning and released. The returned dictionary is then owned by the
+loader state. There is no cancellation, recovery state or retained resource.
+
+## Main sequence
+
+```mermaid
+sequenceDiagram
+    participant Stream as StreamingWorldLoader
+    participant Policy as TerrainChunkLodPolicy
+    participant Planner as TerrainChunkLodPlanner
+    Stream->>Policy: snapshot enabled/radii/chunk size
+    Stream->>Planner: plan(chunks, typed focus, policy)
+    Planner-->>Stream: fresh desired LOD dictionary
+    Stream->>Stream: existing tile state, queue and budget application
+```
+
+## Ownership, threading and resources
+
+- Planner and policy own no engine resources, nodes, RIDs, tasks or caches.
+- The loader retains parsed chunks, desired state and every application side effect.
+- Current calls run synchronously on the renderer main thread; the pure inputs
+  also make isolated contract testing possible without a world scene.
+
+## Errors, cancellation and recovery
+
+| Failure | Detection | Behavior | Diagnostic | Recovery |
+|---|---|---|---|---|
+| Null/wrong focus or policy script | Identity guard | Empty plan | Contract verifier | Supply typed values next refresh |
+| Disabled chunk LOD | Policy flag | Empty plan; existing tile-LOD fallback applies | Existing renderer state | Enable profile option |
+| Empty chunk record | Record guard | Preserve sparse source index; omit record | None | Not an error |
+| Custom negative radius | No normalization | Existing squared-radius behavior is retained | Regression fixture | Change caller configuration if undesired |
+
+There is no asynchronous work or cancellation token.
+
+## Configuration and capabilities
+
+The policy snapshots `use_chunk_terrain_lods`, `lod0_radius_chunks`,
+`lod1_radius_chunks`, `lod2_radius_chunks` and the existing `CHUNK_SIZE`. Inclusive
+squared thresholds and raw custom values deliberately preserve prior behavior.
+
+## Persistence, cache and migration
+
+No serialization or cache format changes. Existing baked terrain, control-splat
+and splat cache versions remain unchanged and require no rebuild.
+
+## Diagnostics and observability
+
+The service emits no logs. The contract verifier reports semantic cases and a
+bounded synthetic timing. Asset-backed p95/p99 remains milestone acceptance work.
+
+## Verification
+
+- `verify_terrain_chunk_lod_planner.gd`: center and vertical invariance,
+  inclusive thresholds, sparse/outside chunks, disabled/custom-negative policy,
+  loader delegation and 250-by-256 bounded planning.
+- Renderer cache, facade, internal-access, baseline, scheduler, target-planner,
+  focus, ground-query and coordinate-boundary regressions remain required.
+- Fidelity evidence is formula preservation only; no new build-12340 visual
+  equivalence claim is made.
+
+## Extension points
+
+- Add measured direction/velocity only through an explicit policy/contract change.
+- Keep queue prioritization and LOD application as separately bounded services.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Pure chunk desired-LOD calculation | Implemented extraction | Asset-free semantic/source-boundary contract | Asset-backed p95/p99 pending |
+| Queue/state/finalization ownership | Remains in loader | Source-boundary regression | Further terrain decomposition required |
+
+## Known gaps and risks
+
+- Raw negative and non-monotonic custom radii retain historical squared/ordered
+  semantics, even though such settings may be surprising.
+- The planner is linear in parsed chunk count and allocates one result dictionary.
+- Terrain build, quality upgrades and geometry lifecycle remain monolithic.
+

+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented extraction |
+| Target/work package | M03 / `M03-RND-TERRAIN-CACHE-SERVICE-001` |

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

+```
+
+Allowed dependencies: `Mesh`, Dictionary/Array scalar containers and the loader
+adapter. Forbidden dependencies: Node/SceneTree/RID, tasks/mutexes, ADT parsing,
+gameplay/network/editor UI, files and persistent Resource cache ownership.
+
+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `TerrainQualityMeshCache.store(tile_key, mesh, source, capacity)` | Command | Admit/touch a Mesh and trim oldest entries | Owning renderer thread/session | Returns false for rejected input or immediate zero-capacity eviction |
+| `TerrainQualityMeshCache.restore(tile_key)` | Query/touch | Return a fresh Mesh/source record and mark newest | Owning renderer thread | Empty on miss; invalid record is removed |
+| `TerrainQualityMeshCache.clear()` | Lifecycle command | Release all retained Mesh references and LRU keys | Reset/shutdown | Idempotent |
+| `TerrainQualityMeshCache.diagnostic_snapshot()` | Read model | Detached count and oldest-to-newest key/source list | Caller-owned result | Never exposes Mesh references |

+| Output | Detached diagnostics | Cache | Tests/future metrics | Caller-owned scalars | One query |
+
+Side effects are limited to retained reference and LRU container mutation. There

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

+| Target/work package | M02 / M02-GMP-TERRAIN-QUERY-001; M03 renderer consumer `M03-RND-FACADE-GROUND-QUERY-001` |
+| Owners | Gameplay terrain-query contract; ADT adapter owns parsed tile cache |
+| Last verified | `a45d521`, 2026-07-14 |
+| Profiles/capabilities | Current sandbox ADT ground height; loaded-render-mesh diagnostic query; authoritative physics backend planned |
+
+## Purpose
+
+Provide a replaceable, scene-free ground-height query for player movement.
+Isolate native ADT loading, per-tile caching, chunk selection and legacy outer
+height-grid interpolation from the player scene behind a typed
+`GodotWorldPosition → TerrainGroundSample` contract.
+
+## Non-goals
+
+- Own player transforms, movement velocity or ground-snap policy.
+- Provide collision normals, slopes, holes, liquids, WMO/M2 collision or ray queries.
+- Change ADT topology, coordinate conversion, renderer caches or native parser format.
+- Claim original-client terrain-contact parity from height regression alone.
+- Couple gameplay to the monolithic streaming renderer before a public backend exists.
+
+## Context and boundaries
+
+```mermaid

+```
+
+Allowed dependencies:
+
+- Typed `GodotWorldPosition` and `CoordinateMapper` contracts.
+- Existing native `ADTLoader` at the ADT adapter boundary.
+- Dynamic dictionaries only inside the native-format adapter.
+- Player scene composition may inject any `TerrainQuery` implementation.
+- Renderer diagnostics reuse `GodotWorldPosition` through `WorldRenderFacade`
+  but return renderer-owned `RenderedGroundSample`, preserving the render/gameplay boundary.
+
+Forbidden dependencies:
+
+- `TerrainQuery` contract depending on Nodes, cameras, input or renderer state.
+- Player scene loading/parsing ADT data or owning a parsed tile cache.
+- Manual WoW/Godot/ADT world-coordinate conversion outside `CoordinateMapper`.
+- Terrain query mutating transforms, gameplay movement state or visual meshes.

+| `ThirdPersonWowController.set_terrain_query(query)` | Composition method | Replaces terrain backend independently of movement/presentation | Call before scene ready or on main thread | Null is rejected and current query retained |
+| `WorldRenderFacade.sample_ground_height(position)` | Separate renderer diagnostic API | Samples already loaded terrain Mesh and returns `RenderedGroundSample` without exposing streamer state | Main thread; immutable sample | Stable `render_terrain_*` unavailable code; not injected into player by default |
+
+## Inputs and outputs

+| Output | `TerrainGroundSample` | Terrain query | Player ground-snap adapter | Immutable caller-held value | One query |
+| Output | Failure code | Terrain query | Diagnostics/tests | Immutable `StringName` | Sample lifetime |
+
+Side effects:
+
+- Production adapter performs lazy file existence check and native ADT parse on first tile query.
+- Adapter mutates only its per-query tile/failure caches.
+- No scene tree, transform, renderer RID, network, database or persisted setting mutation occurs.

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

+
+## Inputs and outputs
+
+| Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
+|---|---|---|---|---|---|
+| Input | Camera action `InputEvent` | Godot/player dispatch | Camera rig | Engine-owned event | One dispatch |

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

+
+## Ownership, threading and resources
+
+- `EntityPresentationSnapshot` owns copied scalars/strings and immutable references
+  to caller-owned identity/position values; it owns no Node, Resource or RID.
+- `WorldEntityPresenter` owns its dictionary and every visual root attached below it.
+- A dictionary entry retains the latest snapshot only while the entity is presented;
+  diagnostics expose no Node, Resource or snapshot reference.
+- Scene load, instantiation, transform mutation, replacement and removal are main-thread only.
+- Successful replacement instantiates first, then detaches the previous root, so an
+  invalid/missing new asset cannot erase the last valid presentation.
+- Parent SceneTree teardown owns attached children; `_exit_tree` drops the index so
+  no stale lookup survives world unload.

+| Unknown remove | Dictionary lookup | No mutation; return `false` | Caller command result | Reconcile registry/presentation lifecycle |
+| World teardown | Scene lifecycle | SceneTree frees children; index clears | Shutdown regression | Recreate service with next world |
+
+There is no background job to cancel. Synchronous asset load is an explicit
+prototype limitation and must be replaced/budgeted before network-scale use.
+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Contract version | `1` | All | No | Identity/path/position/yaw/scale/visibility full snapshot |
+| Present semantics | Idempotent by `EntityId` | Runtime/tools | No | Duplicate snapshots do not duplicate roots |
+| Resource loading | Synchronous on create/replace | Prototype only | No | Not accepted as frame-critical production path |
+| Local player | Separate composition | Current sandbox | No | Prevents facade service from owning gameplay player root |
+
+## Persistence, cache and migration
+
+- No snapshot, entity key or resource instance is persisted.
+- `EntityId` remains session-local and must never enter content/cache schemas.
+- Resource paths are current renderer adapter inputs, not stable content identity.
+- Contract version 1 is additive. Changing identity lifetime, coordinate basis or
+  persisted representation requires a migration and ADR.
+
+## Diagnostics and observability
+
+- `entity_presentation_snapshot()` reports contract version, entity count and a
+  sorted list of `EntityId.to_debug_key`, visual path and visibility.
+- The snapshot is deep-detached by the facade and contains no Node/Resource/RID.
+- Load/type failures include the visual path but never proprietary bytes.
+- Future performance telemetry should measure create/replace duration and active
+  entity/material/RID counts before introducing pooling or batching.
+
+## Verification
+
+- `src/tools/verify_world_entity_presentation.gd` covers eight value-contract and
+  fourteen lifecycle/ownership cases with repository-owned asset-free scenes.
+- `src/tools/verify_world_render_facade.gd` covers command delegation, detached
+  diagnostics and both runtime scene service paths.
+- Identity, coordinate, renderer-internal-access, shutdown, manifest, planner,
+  scheduler and documentation gates remain required.
+- Fidelity boundary: runtime emits no entity commands yet, so existing seven
+  checkpoint scenes remain unchanged. No build-12340 display/animation parity is claimed.
+
+## Extension points
+
+- AssetRepository/display-ID adapter that produces validated visual descriptors.
+- Async/budgeted load and main-thread finalize behind the same facade commands.
+- Animation/equipment/effect snapshots after build-12340 fixtures define behavior.
+- Spatial batching/MultiMesh only after profiling proves per-Node overhead.
+- Entity registry adapter that maps `WowGuid` to session `EntityId` outside render.
+
+## Capability status
+
+| Capability | Status | Evidence | Gap/next step |
+|---|---|---|---|
+| Typed entity visual input | Implemented contract | Versioned immutable validation fixtures | Asset/display mapping not implemented |
+| Present/update/remove lifecycle | Implemented boundary | Asset-free create/update/replace/remove tests | Network-scale async/budget path missing |
+| Deterministic ownership | Implemented | One presenter-owned root per EntityId; teardown checks | RID/material budgets remain future work |
+| WoW entity visual fidelity | Planned | No claim | Requires build-12340 display/equipment/animation fixtures |
+
+## Known gaps and risks
+
+- Synchronous PackedScene load may hitch and is not a production hot-path design.
+- Resource path is renderer adapter data, not stable authored content identity.
+- Full snapshots currently cover transform/visibility only, not animation/equipment/effects.
+- One Node3D per entity is unprofiled at world scale; batching is deliberately deferred.
+- The local player remains separately composed until gameplay/network architecture is ready.

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

+- `WorldRenderFacade` owns only scene-relative adapter paths. It does not own the
+  streamer, environment controller, focus source, returned metrics, queues,
+  caches, nodes or RIDs.
+- `WorldEnvironmentSnapshot` is an immutable caller-owned scalar value. Neither
+  facade nor sky controller retains it; the controller copies normalized hours

+- `WowSkyController` continues to own DBC sampling state and mutations of its
+  duplicated Godot `Environment`, sun, skybox node and world shader globals.
+- `WorldEntityPresenter` owns one optional visual Node3D subtree per presented
+  `EntityId`; it owns no authoritative entity state and excludes the local player.
+- Entity presentation snapshots remain caller-owned inputs. Detached diagnostics
+  expose only identity debug keys, paths and visibility, never Node/Resource/RID.
+- `TerrainQualityMeshCache` owns only full-quality revisit Mesh references and
+  LRU keys. The loader retains terrain tasks/results, tile state, source choice,
+  cache versions and every material/Node/RID finalization side effect.
+- `TerrainChunkLodPlanner` is stateless and owns only call-local horizontal
+  distance calculations. The loader retains parsed chunks, desired state,
+  queues, budgets and all Mesh/Node/RID application side effects.
+- `TerrainChunkGeometryQueuePlanner` is stateless and owns only call-local
+  create/remove request calculation and sorting. The loader adopts the fresh
+  arrays and retains removal-first drains, budgets and render side effects.
+- `M2UniquePlacementRegistry` owns only positive unique-key to tile-key strings.
+  The loader retains owned/skipped tile arrays, candidate retry, grouping/build
+  tasks, caches and all MultiMesh/Node/Mesh/material/RID side effects.
+- Rendered-ground query results and diagnostic snapshots are caller-owned values;
+  the facade never returns Mesh, Node, tile-state or queue references.
+- Loaded-mesh ground sampling is renderer diagnostics, not authoritative gameplay
+  collision. M02 `TerrainQuery` composition and ADT cache ownership remain unchanged.
+- `StreamingTargetPlanner` is stateless and owns only call-local calculations;
+  its immutable plan is consumed synchronously by the streamer.
+- `RenderBudgetScheduler` owns only per-frame lane counters and a terminal
+  cancellation flag. The streamer retains queue ordering and all operation side effects.
+- Focus producers own the immutable `StreamingFocus` reference; the loader retains
+  the latest reference and converts it to `Vector3` only inside the render boundary.

 - Logs: `HITCH`, `PERF`, `TERRAIN_QUALITY`, `SKY_LIGHT`, `SKYBOX_MODEL`.
+- API snapshot: `WorldRenderFacade.renderer_metrics_snapshot()` returns detached
