+## 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 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
+
+Audit every merged M02 package on current master, record final structural and
+fidelity evidence, close M02 and activate M03 only when all target and repository
+gates pass.
+
+## Non-goals
+
+- Change player, movement, terrain, camera, presentation or renderer behavior.
+- Claim complete WoW 3.3.5a locomotion/camera parity.
+- Implement recorded jump/fall/swim/fly, collision or timing gaps.
+- Commit proprietary assets, generated UIDs, caches or user scene changes.
+
+## Paths
+
+- Exclusive: M02/M03 target status, M02 final Evidence, all M02 claim acceptance markers
+- Shared/hotspots: `targets/README.md`, `targets/DEVELOPMENT_ROADMAP.md`, this claim
+- Generated/ignored: local Godot imports, native DLL, renderer corpus and `user://` reports
+
+## Contracts and data
+
+- Runtime APIs, Input Map actions, fixture schemas and cache formats: unchanged
+- Consumers: milestone sequence and future M03 renderer-facade packages
+- Fidelity classification distinguishes direct build-12340 binding evidence,
+  server/reference compatibility evidence and explicitly unverified gaps
+
+## Dependencies
+
+- Requires: all seven M02 READY packages integrated through master `eb122d5`
+- Blocks: M03 activation
+- External state: private original-client files are hash/provenance inputs only
+
+## Verification
+
+- Commands: all M02 input/movement/capability/terrain/camera/presentation tests,
+  coordinate/streaming boundaries, unified renderer dry-run, documentation,
+  coordination and diff hygiene
+- Fidelity evidence: build-12340 default binding hashes and selected facts;
+  pinned TrinityCore turn rate; public reference routing; explicit remaining gaps
+- Performance: no runtime change; renderer baseline remains the performance guard
+
+## Documentation deliverables
+
+- M02 final target Evidence/checklist and limitation statement

+- State: ready-for-review
+- Done: accepted seven M02 packages, reran post-merge gates, recorded complete

+- 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.

+- Commit: `3d528e3`
+- Integration: accepted in master merge `a100ced`
+- Results: `WorldRenderFacade` is the runtime/tool surface for typed focus and

+- 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

+
+## 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.

+## 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

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

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

+# M03-RND-FACADE-ENVIRONMENT-001 — Renderer environment snapshot boundary
+
+<!-- OPENWC_CLAIM:M03-RND-FACADE-ENVIRONMENT-001:sindo-main-codex:2026-07-18 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-facade-environment`
+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Add an immutable world-environment snapshot accepted by `WorldRenderFacade`,
+delegate it to the existing DBC sky controller, and migrate deterministic render
+checkpoint time setup away from direct sky-controller property mutation.
+
+## Non-goals
+
+- Change Light/Area/Skybox DBC selection, interpolation, fog, sun or shader rules.
+- Add weather, indoor lighting, new clock semantics or build-12340 parity claims.
+- Extract the sky service or move its Environment/Node/RID ownership.
+- Change runtime scene defaults, cache formats, streaming behavior or target status.
+
+## Paths
+
+- Exclusive: `src/render/environment/world_environment_snapshot.gd`,
+  `src/tools/verify_world_environment_snapshot.gd`, this claim
+- Shared/hotspots: `src/render/world_render_facade.gd`,
+  `src/scenes/sky/wow_sky_controller.gd`, both runtime streaming scenes,
+  `src/tools/capture_render_checkpoints.gd`,
+  `src/tools/verify_world_render_facade.gd`, `docs/modules/world-renderer.md`,
+  `docs/modules/README.md`, `RENDER.md`, `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Public API: immutable `WorldEnvironmentSnapshot` and
+  `WorldRenderFacade.apply_environment_snapshot`
+- Snapshot input: finite time-of-day hours normalized into one 24-hour day
+- Adapter: explicit `world_environment_controller_path`; facade/controller retain
+  no ownership of caller snapshot
+- Schema/cache/coordinate contracts and runtime defaults: unchanged
+- Consumer: deterministic renderer checkpoint capture; future world-state adapter
+
+## Dependencies
+
+- Requires: integrated M03 facade/ground-query master `cb103e1`
+- Blocks: completion of the facade environment checklist slice and later sky extraction
+- External state: none for contract tests; visual comparison still needs proprietary corpus
+
+## Verification
+
+- Commands: dedicated cold snapshot contract, facade delegation/wiring regression,
+  capture source-boundary regression, renderer manifest/dry-run and repository gates
+- 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
+  visual logic; seven checkpoint plans remain valid
+- Performance budget: one immutable value allocation per environment update and
+  constant-time main-thread delegation
+
+## 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,
+  event bus, service container or alternate Environment owner
+- Unavoidable complexity and justification: facade resolves a separate scene-owned
+  sky controller because the streamer does not own outdoor environment rendering
+- Measured optimization evidence: not applicable; bounded constant-time adapter
+
+## Status
+
+- State: ready-for-review
+- Done: immutable value, facade/controller adapter, checkpoint migration,
+  regressions and renderer module documentation
+- Next: M03 integrator reviews and merges `2ee647a`
+- Blocked by:
+
+<!-- OPENWC_HANDOFF:READY:M03-RND-FACADE-ENVIRONMENT-001:2ee647a -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-FACADE-ENVIRONMENT-001:c69abd6 -->
+
+## Handoff
+
+- Commit: `2ee647a`
+- Results: `WorldEnvironmentSnapshot` normalizes finite time into one day and
+  exposes non-finite failure explicitly. `WorldRenderFacade` delegates the
+  immutable value to the existing sky controller; checkpoint capture no longer
+  locates or mutates that controller directly.
+- Verification: snapshot `contract=5`; facade `delegation=6 ground_contract=2
+  environment_contract=7 runtime_scenes=2 tools=3`; internal access `43/7/9/1`;
+  terrain, coordinate (`files=116 consumers=5`), manifest (`7/7`), shutdown,
+  scheduler (`20000` iterations), planner (`250` iterations), focus, editor parse,
+  dry-run capture, coordination, documentation and diff gates passed.
+- Fidelity: applying a snapshot retains the previous three fixed-clock assignments
+  and leaves DBC profile/area/skybox lookup, interpolation, fog, sun, shader,
+  cache and streaming rules unchanged. Dry-run retained all seven plans and
+  reported dusk as `time=19.00`. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts
+  were copied from master for parse/dry-run only. Missing proprietary ADT/DBC/
+  character data produced expected degraded diagnostics.
+- Remaining risks: the snapshot currently covers exact world time only; weather,
+  indoor state and asset-backed paired zone-transition evidence remain open.
+- Documentation updated: inline value/facade/controller API plus world-renderer
+  API/input-output/data-flow/sequence/ownership/failure/capability/source-map and
+  `RENDER.md` implementation notes.
+- Integration: accepted in master merge `c69abd6`; post-merge snapshot, facade,
+  internal-access, manifest, shutdown, scheduler, planner and focus gates passed.

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

+
+## Non-goals
+
+- Replace the M02 gameplay-owned `TerrainQuery`/`AdtTerrainQuery` composition.

+- Sampling source: loaded quality or tile-LOD Mesh and its live tile transform
+- M02 ADT query cache, renderer cache versions and coordinate contracts: unchanged
+
+## Dependencies
+
+- Requires: M02 terrain query contract and integrated M03 facade/access gate `53d84cc`
+- Blocks: removal of renderer diagnostic internal-access exception and later terrain service extraction
+- External state: asset-backed probe is optional; contract tests use a facade double
+
+## Verification
+
+- Commands: facade query/snapshot isolation contract, internal-access gate,
+  terrain-query regression, focus/coordinate/manifest/shutdown regressions and repository gates
+- Fixtures: available/unavailable sample, detached diagnostic, probe source migration
+- Fidelity evidence: mesh ray/nearest fallback algorithm moves unchanged from the probe
+- Performance budget: on-demand diagnostic query only; no per-frame query added
+
+## Documentation deliverables

+- Inline facade/streamer API docs
+- World-renderer API/data-flow/sequence/ownership/recovery/source-map updates
+- Terrain-query backend status/ownership clarification and renderer implementation note

+
+## 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;

+- 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.

+  `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

+## 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

+## Documentation deliverables

+<!-- OPENWC_CLAIM:M03-RND-TERRAIN-CACHE-SERVICE-001:sindo-main-codex:2026-07-18 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-terrain-quality-cache`
+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Extract the full-quality terrain revisit Mesh cache, its LRU ownership and
+source-admission rules from `StreamingWorldLoader` into a small scene-free
+`TerrainQualityMeshCache`, preserving all call sites and observable behavior.
+
+## Non-goals
+
+- Move ADT parsing, tile state, quality-upgrade tasks/results or SceneTree/RID finalization.
+- Change cache capacity defaults, quality profiles, source priority or cache formats.
+- Cache control-splat/splat meshes that the current loader deliberately rejects.
+- Extract chunk LOD, terrain material building, ground query or other asset services.
+- Add dependencies, persistence, background work or mark the terrain service complete.
+
+## Paths
+
+- Exclusive: `src/render/terrain/terrain_quality_mesh_cache.gd`,
+  `src/tools/verify_terrain_quality_mesh_cache.gd`,
+  `docs/modules/terrain-quality-mesh-cache.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,
+  `src/tools/verify_render_runtime_cache_shutdown.gd`,
+  `docs/modules/world-renderer.md`, `docs/modules/README.md`, `RENDER.md`,
+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated resources, caches and
+  proprietary renderer corpus
+
+## Contracts and data
+
+- Public service API: `store`, `restore`, `clear`, detached `diagnostic_snapshot`
+- Entry: tile key, retained Mesh reference and source string
+- Admission: non-empty key, non-null Mesh, source other than
+  `control_splat_cache`, `splat_cache` or `splat`
+- LRU: successful restore touches newest; store touches then trims oldest to
+  `max(0, capacity)`; invalid restored records are removed
+- Persistence/cache format: none; session-memory ownership only
+
+## Dependencies
+
+- Requires: integrated facade contracts master `61bad09`
+- Blocks: later terrain service extraction and cache/finalization acceptance audit
+- External state: none; tests use synthetic ArrayMesh references
+
+## Verification
+
+- Commands: dedicated cache contract/LRU/ownership regression; streamer source
+  boundary; shutdown/facade/internal-access/manifest/planner/scheduler and repository gates
+- Fixtures: admission/rejection, replacement, LRU touch/eviction, zero/negative
+  capacity, invalid record cleanup, clear and detached diagnostics
+- Fidelity evidence: same sources/capacity/call sites; all seven baseline plans unchanged
+- Performance budget: dictionary lookup plus bounded single-entry LRU operations;
+  no Node, task, file, cache serialization or RID creation
+
+## Documentation deliverables
+
+- Inline public API docs: store/restore/clear/diagnostics and ownership
+- Module specification: new terrain quality mesh cache specification
+- Data-flow diagram: upgrade result through cache to revisit state
+- Sequence/state/dependency diagrams: store/restore/evict/reset and failure paths
+- Source map/status updates: module registry, world renderer and `RENDER.md`
+
+## Simplicity and naming
+
+- Important names introduced: `TerrainQualityMeshCache`
+- Simplest considered solution: one RefCounted with dictionary plus ordered tile-key array
+- Rejected complexity/abstractions: generic cache framework, weak references,
+  callbacks, Resource cache integration, background eviction or persistence
+- Unavoidable complexity and justification: Mesh references must survive unloaded
+  tile state while LRU keeps revisit memory bounded
+- Measured optimization evidence: exact ownership extraction, no optimization claim
+
+## Status
+
+- State: ready-for-review
+- Done: scene-free cache ownership/LRU extraction, loader adapter migration,
+  contract regression and module documentation
+- Next: M03 integrator reviews and merges `97480e0`
+- Blocked by:
+
+<!-- OPENWC_HANDOFF:READY:M03-RND-TERRAIN-CACHE-SERVICE-001:97480e0 -->
+<!-- OPENWC_INTEGRATION:ACCEPTED:M03-RND-TERRAIN-CACHE-SERVICE-001:630a0c1 -->
+
+## Handoff
+
+- Commit: `97480e0`
+- Results: `TerrainQualityMeshCache` now owns retained full-quality Mesh
+  references, source admission and oldest-to-newest LRU. The loader retains only
+  restore-to-state, store-after-upgrade and clear lifecycle adapters.
+- Verification: cache `contract_cases=15 loader_calls=3`; facade/entity/ground/
+  terrain regressions; internal access `private_symbols=42 gameplay=7
+  editor_sources=9 renderer_tools=1`; manifest `7/7`; shutdown; scheduler
+  `20000` iterations; planner `250` iterations; focus; editor parse; dry-run;
+  coordination, documentation and diff gates passed.
+- Fidelity: `baked_full` revisit retention, three excluded splat sources, LRU
+  touch/trim, profile capacities and all call sites remain unchanged. All seven
+  checkpoint plans remain valid. No visible or build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT scripts supported
+  parse/dry-run only; missing proprietary ADT/DBC/character data produced expected diagnostics.
+- Remaining risks: entry count does not measure Mesh bytes; ordered-array touch
+  remains linear; asset-backed revisit flash, memory and p95/p99 evidence remain pending;
+  terrain build/tasks/state/finalization are still monolithic.
+- Documentation updated: new terrain cache API/input-output/data-flow/lifecycle/
+  sequence/ownership/failure/configuration/migration/diagnostic/source-map spec;
+  world renderer, registry and `RENDER.md` updated.
+- Integration: accepted in master merge `630a0c1`; post-merge cache, facade,
+  internal-access, manifest, shutdown, scheduler and planner gates passed.

+# Render Budget Scheduler
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Implemented |
+| Target/work package | `M03-RND-SCHEDULER-001` |
+| Owners | Renderer workstream / M03 integrator |
+| Last verified | Worktree `work/sindo-main-codex/m03-render-budget-scheduler`, 2026-07-16 |
+| 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.

+
+Allowed dependencies are Godot value containers and `RefCounted`. The module
+must not depend on `Node`, `WorkerThreadPool`, `ResourceLoader`, `RenderingServer`,
+mutexes, renderer assets or streamer queue fields.

+| `has_remaining_permit` | Query | Tests a lane without consuming | Main thread; current frame | Unknown/exhausted/cancelled returns `false` |
+| `try_consume_permit` | Mutation | Atomically checks and consumes one caller operation permit | Main thread; current frame | Unknown/exhausted/cancelled returns `false` |
+| `remaining_permits` | Query | Returns a lane's current unconsumed count | Main thread; current frame | Unknown/cancelled returns zero |
+| `consumed_permits_snapshot` | Query | Returns detached per-lane diagnostics | Caller owns returned dictionary | Mutation cannot affect scheduler state |
+| `cancel` | Lifecycle method | Permanently stops new permits and clears remaining limits | Main thread; renderer teardown | Idempotent; does not interrupt in-flight caller work |
+| `is_cancelled` | Query | Reports terminal lifecycle state | Scheduler lifetime | No failure |
+
+## Inputs and outputs

+
+The scheduler has no I/O, logging, SceneTree, task, cache or GPU side effects.

+
+Cancellation is intentionally terminal. A new renderer scene creates a new
+scheduler instance; an old instance cannot accidentally resume after teardown.

+
+## 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

+- Mutate load/finalize/eviction queues.
+- Prioritize queued tile paths by world distance.
+- Calculate chunk or tile LOD levels after a tile is loaded.
+- Own the available WDT tile catalog or cache paths.
+- Create, cancel or await jobs.
+- Implement M2, WMO, liquid or terrain attachment.

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

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

+
+## Metadata

+| 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.

+
+## 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.

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

 ## Public API

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

 ## Ownership, threading and resources

 - `StreamingWorldLoader` владеет tile states, queues, task registries, active world instances и render caches session scope.
+- `WorldRenderFacade` owns only scene-relative adapter paths. It does not own the
+  streamer, environment controller, focus source, returned metrics, queues,
+  caches, nodes or RIDs.
+- `WorldEnvironmentSnapshot` is an immutable caller-owned scalar value. Neither
+  facade nor sky controller retains it; the controller copies normalized hours
+  into its existing fixed-clock fields on the main thread.
+- `WowSkyController` continues to own DBC sampling state and mutations of its
+  duplicated Godot `Environment`, sun, skybox node and world shader globals.
+- `WorldEntityPresenter` owns one optional visual Node3D subtree per presented
+  `EntityId`; it owns no authoritative entity state and excludes the local player.
+- Entity presentation snapshots remain caller-owned inputs. Detached diagnostics
+  expose only identity debug keys, paths and visibility, never Node/Resource/RID.
+- `TerrainQualityMeshCache` owns only full-quality revisit Mesh references and
+  LRU keys. The loader retains terrain tasks/results, tile state, source choice,
+  cache versions and every material/Node/RID finalization side effect.
+- Rendered-ground query results and diagnostic snapshots are caller-owned values;
+  the facade never returns Mesh, Node, tile-state or queue references.
+- Loaded-mesh ground sampling is renderer diagnostics, not authoritative gameplay
+  collision. M02 `TerrainQuery` composition and ADT cache ownership remain unchanged.
+- `StreamingTargetPlanner` is stateless and owns only call-local calculations;
+  its immutable plan is consumed synchronously by the streamer.
+- `RenderBudgetScheduler` owns only per-frame lane counters and a terminal
+  cancellation flag. The streamer retains queue ordering and all operation side effects.
 - Focus producers own the immutable `StreamingFocus` reference; the loader retains
  the latest reference and converts it to `Vector3` only inside the render boundary.
 - Worker tasks не должны менять SceneTree и shared Resource concurrently.

 ## Steps

- [ ] Ввести `WorldRenderFacade` для focus, environment, entity visuals, ground query и metrics.
- [ ] Запретить gameplay/editor доступ к внутренним очередям streamer.
- [ ] Извлечь pure `StreamingTargetPlanner`.
- [ ] Извлечь `RenderBudgetScheduler` с bounded queues/cancellation.

+- Results: scheduler `cases=6 iterations=20000 elapsed_ms=10.216`; planner
+  `cases=5 average_ms=1.804`; facade/focus passed; coordinate boundary
+  `files=111 consumers=6`; renderer manifest retained `7/7` checkpoints;
+  shutdown ownership and repository gates passed. Internal-access gate additionally
+  derived `43` private symbols and found no forbidden access across `7` gameplay
+  and `9` EditorPlugin-package sources plus the terrain probe. Ground facade passed
+  `delegation=5 ground_contract=2`; cold `RenderedGroundSample contract=3`;
+  environment integration passed cold snapshot `contract=5` and facade
+  `delegation=6 environment_contract=7`; dry-run retained all `7/7` plans and
+  applied the dusk checkpoint at `time=19.00`. Entity presentation passed
+  `snapshot_cases=8 lifecycle_cases=14 runtime_scenes=2`; facade expanded to
+  `delegation=9 entity_contract=6`, while character presentation remained `9/10/3/1`.
+  Terrain quality cache passed `contract_cases=15 loader_calls=3`; internal-access
+  inventory decreased to `42` because the loader no longer owns the LRU-order field.
+  M02 terrain-query regression
+  remained green (13 pre-existing expired M00 claim warnings).
+- Fidelity comparison: all 16 historical operation limits and drain sites were
+  preserved; chunk removal/create retain their shared removal-first budget.
+  Defaults, quality presets, cache versions and visual rules are unchanged.
+  Rendered-ground diagnostics preserve the prior 5000-unit ray, 3x3 search and
+  `2/5/10/20/40`-unit nearby fallback while hiding mutable renderer state.
+  Environment snapshots preserve the prior fixed-clock assignments while DBC
+  profile/area/skybox selection, interpolation, fog, sun and shader rules remain unchanged.
+  Runtime produces no world-entity commands yet, so player/world output and all
+  baseline plans remain unchanged by the new present/remove ownership boundary.
+  Terrain revisit cache retains the same admitted/excluded sources, LRU touch/trim,
+  profile capacities and three loader adapter sites; no cache format changed.
+  No new build-12340 parity claim is made; asset-backed visual/p95/p99 comparison remains pending.
+- Changed files: scene-free scheduler and verifier; streamer budget composition/
+  permit delegation; scheduler module spec; world renderer/module registry/RENDER notes;
+  renderer-owned ground sample, facade/loader ground query, migrated terrain probe,
+  immutable environment snapshot, facade/sky adapter, migrated checkpoint time input,
+  contract-v1 entity snapshot, renderer-owned entity presenter, runtime composition,
+  scene-free terrain quality Mesh cache and loader store/restore/clear adapters,
+  expanded facade/internal-access/coordinate verifiers; work-package claims and this evidence.
+- Remaining risks: queue storage length and worker concurrency/stale-result logic
+  remain streamer-owned; cancellation stops new permits but does not interrupt
+  in-flight work; the environment snapshot currently covers world time but not weather
+  or indoor state; entity PackedScene loading is synchronous and not accepted for
+  network-scale hot paths; terrain cache is entry-count bounded without Mesh-byte
+  metrics and the remaining terrain build/tasks/state/finalization stay monolithic;
+  M03 still needs further terrain/M2/WMO/liquid service extraction
+  and dependency/performance acceptance.
