# M03 — Renderer Facade and Safe Extraction

<!-- OPENWC_TARGET:ACTIVE -->

## Outcome

Закрыть монолитный streamer стабильным API и постепенно извлечь тестируемые подсистемы без rewrite.

## Steps

- [x] Ввести `WorldRenderFacade` для focus, environment, entity visuals, ground query и metrics.
- [x] Запретить gameplay/editor доступ к внутренним очередям streamer.
- [x] Извлечь pure `StreamingTargetPlanner`.
- [x] Извлечь `RenderBudgetScheduler` с bounded queues/cancellation.
- [ ] Затем извлекать terrain, M2, WMO и liquid services по одному.
- [ ] Сохранить cache versioning и main-thread GPU finalization rules.
- [ ] Добавить dependency и performance regression checks.

## Fidelity evidence

Все baseline checkpoints сравниваются до/после; placement, visibility, animation и materials не меняются без отдельной fidelity-задачи.

## Exit criteria

Runtime и Editor используют facade; planner/scheduler тестируются без полного мира; p95/p99 и hitch budgets не хуже согласованного baseline.

  `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

  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.
  Chunk LOD keeps horizontal XZ chunk-center distance, inclusive squared thresholds,
  sparse-index omission and raw negative-radius squaring at both loader call sites.
  Chunk operation planning preserves stable removals, nearest-first create sorting,
  tile-LOD remove-all takeover, sparse tile-origin fallback and XZ-only distance;
  loader still drains removals first through the shared `chunk_geometry` budget.
  M2 positive `MDDF.uniqueId` retains `uid:<decimal>` first-owner semantics,
  within-call duplicate suppression, cross-tile skip/retry and unkeyed pass-through.
  M2 regular Euler, Elwynn cliff-rock shell correction, waterfall yaw/local-axis
  twist, tall-waterfall anchor compensation, path normalization and caller scale
  clamps are unchanged across worker grouping, placeholders and direct instances.
  M2 worker grouping retains invalid-record filtering, case-sensitive lowercase
  `.mdx/.mdl` conversion, first-seen group/per-group placement order, tile-local
  origin subtraction and the `0.0001` scale clamp.
  M2 build batching retains animated/static limit selection, minimum-one clamp,
  remaining-transform cap and the exact offset/group-completion cursor rules.
  Pending M2 builds retain keyed latest-job replacement, duplicate/stale FIFO
  entries, one-key rotation, strong root/group references and exact group/offset/
  serial progression; releasing queue records still never frees scene nodes.
  M2 build dispatch retains pending-animation priority before batch planning,
  animated-before-static selection, unresolved-static rotation without progress,
  and the historical serial increment for terminally missing positive batches.
  One build operation now carries the exact normalized path, optional animated
  prototype, pending-animation state, optional static Mesh and missing outcome in
  a typed snapshot; releasing it never frees either borrowed engine resource.
  Native GryphonRoost observation now preserves case-insensitive substring
  selection, cached/static priority, synchronous animated raw read, non-empty
  surface and child requirements, first-wins adoption and exact success-log fields.
  Cached animated lookup preserves cached/static/pending priority, empty-
  allowlist rejection, denylist precedence, normalized/lowercase/basename path
  order, animation presence, primitive cap, accepted empty/`pivot_prefix_v1`
  schema rules and request/static-only transitions. Native GryphonRoost remains
  first through its observer, so selection and visible behavior are unchanged.
  Cached animation terminal work retains pending insertion-order polling,
  completion-order FIFO, one popped record per permit, candidate-before-material
  lookup, exact repair/validation/adoption and `M2_ANIM_CACHE` fields.
  WMO cache-key normalization, positive MODF identity with tile/index fallback
  and world position/Euler/unclamped-scale transforms are unchanged across
  lightweight render, cached-scene and live-prototype paths.
  WMO first/idempotent/shared/non-owner/final/global reference behavior is
  unchanged; the extracted registry owns only String reference sets while the
  loader retains the parallel key-to-Node map and final-release cancellation/free.
  Lightweight WMO render groups retain mesh-before-MultiMesh order, one cursor
  increment and one budget permit per valid or null group; completion still
  cancels the job after both raw integer cursor comparisons are exhausted.
  Pending WMO render builds retain typed root/resource/cursors, FIFO order,
  duplicate replacement, stale-front pop, first-occurrence cancel and three
  idempotent clear sites. Queue release never frees engine objects; the loader
  retains validity checks, materialization, permits and Node destruction.
  Lightweight WMO render cache paths retain the same cached/pending/missing
  transitions, retry behavior for absent files and map-reset versus final-shutdown
  lifetime. `ResourceLoader`, script identity and `FORMAT_VERSION` validation
  remain loader-owned before the extracted state accepts a Resource.
  Cached WMO scene paths retain direct negative caching for missing/oversize/
  request-start failures, terminal missing state for load/validation failures and
  the prior transient-reset versus final-shutdown lifetime. File-size limits,
  `PackedScene` probe instantiation, WMOBuilder metadata validation and probe-node
  destruction remain loader-owned before state accepts a scene.
  ADT water requests retain FIFO order and tile-key deduplication; tile release
  removes pending requests without cancelling active work, task completion and
  result publication order are unchanged, and the mutex remains limited to the
  worker/main-thread mailbox. The loader still owns ADT parsing, concurrency and
  profile limits, stale tile/path/root rejection, `WATER_FINALIZE` permits,
  tile subtree lifetime and `water_loaded` timing.
  Both raw-tile and delayed cached-tile water paths now call the same stateless
  finalizer. It invokes the unchanged `ADTBuilder.build_tile_water_scene`,
  attaches the returned root once and applies the existing optional recursive
  Editor ownership; tile subtree lifetime and dry-root cleanup are unchanged.
  M2 stale-cache rebuild selection retains the same positive billboard flag/
  vertex-count tests, referenced non-identity UV rotation, exclusive
  `0.000001` speed threshold, four-stage cap and first-decision-per-path cache
  lifetime. Raw loading, material refresh version, M2Builder rebuild/fallback and
  Mesh adoption remain loader-owned.
  Static M2 mesh pending requests preserve normalized-path dedupe and Dictionary
  insertion polling order; loaded/failed transitions preserve completion-order
  finalization FIFO and opaque statuses. All three pending-plus-finalize metrics,
  both clear sites and shutdown ResourceLoader drain order are unchanged; cache
  path selection, I/O, permits and adoption decisions remain loader-owned;
  missing outcomes now belong to the prototype cache state.
  Animated M2 pending requests preserve normalized-path dedupe and Dictionary
  insertion polling order; loaded/failed transitions preserve completion-order
  finalization FIFO and opaque statuses. All three pending-plus-finalize metrics,
  both clear sites and shutdown ResourceLoader drain order are unchanged. GLB
  eligibility/cache selection, I/O, permits, instantiation, material repair and
  prototype/static-fallback decisions remain loader-owned.
  Animated scene candidates retain PackedScene-only/Node3D-root admission,
  depth-first positional material mapping, source-index clamp, per-surface
  override priority, first-material fallback and at-least-one-AnimationPlayer
  acceptance. Accepted exact roots/player counts return to loader adoption/logs;
  rejected roots are synchronously freed, including the previously leaked
  non-Node3D imported-root edge case. I/O, permits, material-source selection,
  prototype/static outcome and playback policy remain loader-owned.
  Animated instance playback retains the exact path/index hash phase, ordinary/
  fish/bird priority lists, case-insensitive substring and first-name fallbacks,
  linear looping of every imported animation, selected play and positive-length
  phase seek. Native animators retain exact-script depth-first pairing, five
  reference/value assignments, optional prepare, phase and debug sampling.
  Instance duplication/attachment, visibility, shadows, Editor ownership and
  diagnostic log formatting remain loader-owned.
  Prepared static M2 Mesh lookups retain exact Resource identity, same-path
  replacement and map-refresh lifetime; the only clear remains final shutdown
  after asynchronous drain. Shared missing/static/animated prototype state now
  belongs to `M2PrototypeCacheState`; materialization remains loader-owned.
  Direct Mesh Resources, temporary PackedScene instances and prototype/rebuild
  subtrees retain the same depth-first first-Mesh rule. PackedScene still
  instantiates once and frees its temporary root synchronously before return;
  the extractor retains no state or Resource reference.
  Runtime material refresh remains version `2`; current Meshes skip raw loading,
  empty/ordinary data marks and reuses the original, billboard/UV-rotation data
  attempts the same M2Builder rebuild, and failure marks/reuses the original.
  Raw FileAccess/ClassDB M2Loader I/O now belongs to the stateless repository;
  exact path resolution and `load_m2`/`load_m2_animated` names are unchanged.
  Loader-owned normalization, fallback order, builders and result adoption remain
  unchanged; the same prototype/negative transitions now use cache-state methods.
  No new build-12340 parity claim is made; asset-backed visual/p95/p99 comparison remains pending.

- Remaining risks: worker concurrency and stale-result validation 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;
  chunk LOD asset-backed p95/p99 and visual acceptance remain pending;
  chunk queue planning adds a second tile-state pass whose asset-backed p95/p99
  still needs acceptance, while queue drains and geometry finalization remain monolithic;
  private Azeroth data was absent for the asset-backed ADT placement probe; M2
  asset-backed visual transform recheck, grouping/build/tasks/caches/finalization
  and boundary traversal p95/p99 remain pending; path grouping is not yet
  culling-driven spatial-cell grouping; M2 rebuild classification and static
  request/finalize bookkeeping, prepared Mesh cache ownership and first-Mesh
  traversal plus refresh/rebuild/fallback, raw native M2 I/O and prototype/
  negative cache state are separated, but synchronous native parsing/build and
  Mesh adoption remain in the loader call path; cached animation eligibility/
  request admission is extracted while terminal ResourceLoader polling remains;
  raw
  animated-instance materialization is now separated but remains synchronous
  main-thread work; asset-backed traversal/visual/leak/p95/p99 evidence is pending;
  native parsing/build also remains synchronous and the historically unfreed
  childless builder result remains a documented leak edge;
  static MultiMesh materialization is also separated but remains synchronous;
  headless timing does not measure transform upload GPU cost and spatial-cell
  batching still needs culling/performance evidence; typed M2 pending state is
  separated and dispatch decisions are explicit; static and cached-animation
  observers produce typed per-operation state, including native observation;
  animation terminal ResourceLoader drain is extracted, while action execution,
  material-prototype lookup, root cleanup and static Mesh finalize drain remain loader-owned;
  WMO ResourceLoader/FileAccess I/O, live fallback and group materialization
  remain in the loader;
  asset-backed WMO placement/portal/material/leak/p95/p99 evidence remains pending;
  ADT water parsing and active worker interruption remain loader-owned;
  materialization is separated but remains synchronous main-thread work behind
  the existing permit, and asset-backed MH2O/MCLQ traversal/leak/p95/p99/
  original-client evidence is pending; M03 still needs further terrain/M2/WMO/
  liquid service extraction and dependency/performance acceptance.
