 - Added `src/tools/capture_render_checkpoints.gd` to load the Eastern Kingdoms streaming scene, move a dedicated camera to fixed regression viewpoints and save PNGs under `user://render_checkpoints`.
 - Current checkpoints cover the Elwynn waterfall from front/side and Goldshire Inn/Blacksmith windows. Headless runs are dry-run only because the headless display server cannot produce viewport PNGs.
 
+## 2026-07-13 Renderer Shutdown Ownership
+
+- `StreamingWorldLoader` drains its asynchronous work before teardown, leaves parented streamed nodes to SceneTree ownership, then explicitly frees detached M2/WMO prototype nodes and clears resource caches.
+- `ADTBuilder` explicitly frees a temporary `Water` root when an ADT liquid payload produces no child geometry. Dry tiles must not leave empty nodes in ObjectDB.
+- `src/tools/verify_render_runtime_cache_shutdown.gd` regression-checks detached prototype and resource-cache release plus empty-liquid-root ownership. The unified render-baseline runner executes it before capture.
+- A focused 8-second GUI checkpoint and a seven-checkpoint single-pass GUI run finish without Node, renderer resource or RID leak diagnostics. A timing-dependent anonymous zero-reference `RefCounted` ObjectDB warning can remain at engine teardown; it is tracked separately and is not suppressed.
+- This is shutdown-only ownership behavior and does not alter checkpoint rendering, cache formats or the `Blizzlike335` compatibility profile.
+
+## 2026-07-13 Explicit Streaming Focus
+
+- `StreamingWorldLoader` consumes an immutable `StreamingFocus` containing a
+  typed `GodotWorldPosition`; runtime streaming no longer discovers the active
+  `Camera3D` from the viewport or child nodes.
+- Eastern Kingdoms and Kalimdor runtime scenes explicitly use the player as the
+  streaming source. Checkpoint capture and terrain/occluder probes explicitly
+  use their dedicated camera through the same public refresh path.
+- The editor viewport camera remains behind a dedicated editor-only adapter.
+  `camera_path` is retained solely for optional automatic overview positioning.
+- Streaming radii, LOD decisions, cache formats and renderer quality profiles
+  are unchanged by this migration.
+
+## 2026-07-13 Coordinate Conversion Boundary Gate
+
+- Sky/area lookup, streaming tile ownership, player spawn/terrain sampling and
+  terrain diagnostics now cross world-coordinate spaces through typed
+  `CoordinateMapper` methods.
+- Renderer distance, LOD, ray and model-local M2/WMO calculations remain in
+  their existing Godot/local spaces; they are not axis conversions.
+- The repository gate rejects new manual world-center, WoW/Godot and
+  Godot-position-to-ADT formulas. The unified renderer baseline runs this gate.
+- Native ADT/WDT parsers keep one shared world conversion in
+  `wow_chunk_reader.h`; the independent M00 calibration formula remains a test oracle.
+- Coordinate contract version 2, renderer radii, cache formats and visual
+  quality profiles are unchanged.
+
+## 2026-07-13 Golden Server Spawn Renderer Evidence
+
+- The pinned AzerothCore Human Warrior start at server position
+  `(-8949.95, -132.493, 83.5312)` maps through `CoordinateMapper` to Godot
+  `(17199.159666667, 83.5312, 26016.616666667)`, ADT `(32,48)` and MCNK `(3,12)`.
+- `server_spawn_render_manifest.json` drives the ordinary Eastern Kingdoms
+  checkpoint capture pipeline at that location; no live database or production
+  spawn entity is introduced.
+- A renderer-native emissive marker starts at the exact mapped origin and keeps
+  depth testing enabled so GUI evidence exposes its relationship to terrain.
+- `verify_server_spawn_renderer.gd` rejects drift between the pinned fixture,
+  manifest target/player coordinates and expected ADT ownership. The unified
+  renderer baseline runs this contract check before capture.
+- This closes a coordinate/renderer integration criterion only. It does not
+  claim TrinityCore row equivalence or visual parity with the original client.
+
 ## 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.

+- Commit: this work-package commit
+- Results: before the fix the focused capture retained 6 mesh, 6 material, 4 shader, 6 texture, 6 instance and RenderingDevice RIDs (30 resources); after the fix focused and seven-checkpoint captures retained none
+- Remaining risks: D3D12 descriptor fallback remains unrelated; Godot can report a timing-dependent anonymous `RefCounted` whose reference count is already zero, without retained Node/resource/RID ownership

+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m01-coordinate-boundary-gate`
+- Lease expires UTC: 2026-07-15
+- Integrator: M01 milestone integrator
+
+## Outcome
+
+Route remaining GDScript world/tile axis conversions through `CoordinateMapper`
+and add a repository-wide gate that rejects new manual world-center, axis-swap
+or world-to-ADT tile formulas outside explicit contract/native-oracle boundaries.
+
+## Non-goals
+
+- Rewriting model-local M2/WMO vertex or placement orientation transforms.
+- Moving renderer distance/LOD geometry out of Godot space.
+- Replacing the native parser boundary with GDScript calls from worker threads.
+- Changing coordinate contract semantics, renderer radii or cache formats.
+
+## Paths
+
+- Exclusive: `src/tools/verify_coordinate_conversion_boundaries.gd`
+- Shared/hotspots: `src/domain/coordinates/coordinate_mapper.gd`, coordinate
+  tests/docs/ADR, streamer/player/sky/terrain-probe consumers,
+  `docs/CODING_STANDARD.md`, this claim
+- Generated/ignored: Godot import metadata, extracted assets and renderer caches
+
+## Contracts and data
+
+- Additive mapper methods: Godot position to ADT tile/local and ADT tile/local
+  to Godot position
+- Native exception: one formula definition in `src/native/src/wow_chunk_reader.h`;
+  ADT/WDT loaders may call it but may not define copies
+- Oracle exception: `verify_render_coordinate_calibration.gd` retains one
+  independent M00 formula to detect common-mode mapper regressions
+- Model-local transforms are outside the world-coordinate gate
+
+## Dependencies
+
+- Requires: coordinate contract v2 and M01 seams through `7c64e8d`
+- Blocks: M01 coordinate-centralization exit criterion and milestone evidence audit
+- External state: no dependency or proprietary input
+
+## Verification
+
+- Commands: conversion-boundary gate, mapper/golden fixtures, streaming focus,
+  identities, renderer calibration/manifest and repository gates
+- Fixtures: Godot/ADT tile center, local offsets and exact boundaries
+- Fidelity evidence: existing build-12340 points and raw ADT/server fixture remain unchanged
+- Performance budget: mapper allocations occur only at adapter/update boundaries;
+  renderer distance/LOD math remains in Godot scalars
+
+## Documentation deliverables
+
+- Inline public API docs: new mapper methods
+- Module specification/ADR: boundary APIs, allowed exceptions and gate behavior
+- Coding standard: mandatory review rule for cross-space conversions
+- Data-flow diagram: existing coordinate module diagram updated for direct adapters
+- State/sequence diagrams: unchanged; pure synchronous mapping
+
+## Simplicity and naming
+
+- Important names introduced: `godot_to_adt_tile`, `godot_to_adt_tile_local`,
+  `adt_tile_local_to_godot`, `verify_coordinate_conversion_boundaries`
+- Simplest considered solution: extend the existing mapper and scan source text
+  for narrow high-signal formula signatures
+- Rejected complexity/abstractions: generic coordinate algebra framework,
+  native-to-GDScript calls on parser workers and a broad numeric-literal ban
+- Unavoidable complexity and justification: one native boundary and one
+  independent test oracle must remain explicit to avoid worker coupling and common-mode tests
+- Measured optimization evidence: existing renderer distance/LOD scalar math is unchanged
+
+## Status
+
+- State: ready-for-review
+- Done: mapper extensions, consumer migration, repository gate, review rule,
+  integrated renderer gate, regression fixtures and documentation
+- Next: integrator review, merge and M01 completion-evidence audit
+- Blocked by:
+
+## Handoff
+
+- Commit: `47dec6c`
+- Branch: `work/sindo-main-codex/m01-coordinate-boundary-gate`
+- Outcome: all audited GDScript world/tile conversions in sky, streaming,
+  player spawn/ground sampling and terrain probes route through typed
+  `CoordinateMapper` boundaries. A repository scan rejects new manual
+  world-center, legacy axis-conversion, world-to-tile, tile-local and
+  tile-center formulas.
+- Contract/schema: additive `godot_to_adt_tile`,
+  `godot_to_adt_tile_local` and `adt_tile_local_to_godot` APIs; no persisted
+  format, cache version or renderer radius changes.
+- Verification: CoordinateConversionBoundaries PASS (`83` files, one native
+  boundary, one independent oracle, four consumers, six classifier guards);
+  CoordinateMapper PASS (`5` golden points, `8` tile boundaries, `2` raw MCNK,
+  `5` yaw cases); renderer calibration PASS (`5` points, maximum error
+  `0.000015`); renderer manifest PASS (`7/7/7`); unified render baseline dry-run,
+  headless project load, runtime cache shutdown, coordination, documentation
+  and whitespace gates passed.
+- GUI regression: final ADT-boundary capture compared `2/2`, missing `0`,
+  failed `0` (cold mean `0.0002324`, changed ratio `0.0013741`; warm mean
+  `0.0000226`, changed ratio `0.0001285`). Earlier full capture produced all
+  `14` images; `11/14` met the strict changed-pixel threshold. The three
+  threshold-only differences retained low mean error (`<= 0.00622`) and were
+  visually classified as cold M2 readiness and liquid animation phase, with
+  unchanged camera, geometry alignment, area and streaming focus.
+- Fidelity: existing build-12340 calibrated points, raw ADT fixture and server
+  spawn fixture remain unchanged. Native parser workers retain exactly one
+  formula in `wow_chunk_reader.h`; the calibration verifier retains exactly one
+  independent formula so mapper and oracle cannot share a common-mode defect.
+- Rebuild: none. Local ignored extracted assets/native binary/cache junctions
+  were used for runtime checks and are not part of the commit.
+- Remaining risks: source scanning intentionally recognizes narrow high-signal
+  formula signatures rather than parsing arbitrary algebra; native formula
+  parity still relies on calibration/raw fixtures. Model-local M2/WMO basis
+  transforms and Godot-space LOD distance math are intentionally outside scope.
+- Recommended merge order: after `7c64e8d`; this package closes the remaining
+  M01 manual axis-conversion checklist item, but only the milestone integrator
+  may update target Evidence/status or set `OPENWC_TARGET_DONE`.
+- Documentation: coding review rule, coordinate-mapping module API/input-output/
+  data-flow/capability/risk/source-map sections, ADR 0001 and `RENDER.md` were
+  updated. Existing pure synchronous data-flow diagram remains authoritative;
+  no state/sequence diagram changed.

+
+## Non-goals

+
+## 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

+- Data-flow diagram: corrected filename/chunk axes
+- ADR: corrected decision and evidence
+- Sequence/state diagrams: not applicable; pure synchronous mapper

+- Contract/schema: coordinate contract version 2; no persisted format, cache or migration
+- Verification: coordinate mapper PASS (5 build-12340 points, 8 boundaries,

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

+- Migration/compatibility: additive contract; existing renderer conversions remain
+  unchanged until a later consumer migration package
+- Consumers: future renderer, network, gameplay and server-data adapters

+
+## 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

+- Unavoidable complexity and justification: distinct source spaces prevent silent axis swaps
+- Measured optimization evidence: not applicable

+- Commit: `f45695c`
+- Branch: `work/sindo-main-codex/m01-coordinate-mapper`

+  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

+Add scene-free, immutable identity values for stable authored content,

+
+## Non-goals

+- Defining map/spell/item/quest/display/sound IDs in this package.
+- Migrating gameplay, network or Content Project consumers that do not exist yet.

+
+## 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

+- 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

+- 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,

+- Unavoidable complexity and justification: server entry namespace and split GUID
+  words prevent collisions and signed 64-bit loss
+- Measured optimization evidence: not applicable
+

+- 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;

+- 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

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

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

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

+  coordinate/world-renderer module documentation, `RENDER.md`, this claim
+- Generated/ignored: Godot UIDs/import metadata and `user://` PNG/JSON evidence
+
+## Contracts and data
+
+- Fixture schema and coordinate contract version remain unchanged.
+- Additive diagnostic checkpoint metadata may request a renderer-native marker;
+  existing M00 checkpoints remain byte-for-byte compatible.
+- The spawn remains sourced from pinned AzerothCore revision
+  `68fcf0098b16388093989627f37be530fc91f07d`.
+
+## Dependencies
+
+- Requires: merged M01 packages through `a07a487`
+- Blocks: M01 golden server-spawn renderer criterion and milestone closeout
+- External state: GUI capture requires the existing local extracted/cached
+  renderer corpus; headless contract verification remains non-proprietary
+
+## Verification
+
+- Commands: dedicated spawn verifier, coordinate fixture/mapper/boundary gates,
+  renderer baseline dry-run, GUI checkpoint capture and human inspection
+- Fixture: AzerothCore race `1`, class `1`, map `0`, server position
+  `(-8949.95, -132.493, 83.5312)`
+- Expected renderer result: Godot position
+  `(17199.159666667, 83.5312, 26016.616666667)`, ADT `(32,48)`, MCNK `(3,12)`
+- Fidelity classification: server/coordinate integration evidence only; it does
+  not establish full original-client visual parity
+
+## Documentation deliverables
+
+- Inline API/tool documentation for new verifier and marker metadata
+- Coordinate-mapping module capability/evidence update
+- World-renderer checkpoint input/output/source-map update when marker support is added
+- Existing synchronous coordinate data-flow diagram updated only if flow changes
+
+## Simplicity and naming
+
+- Important names: `server_spawn_render_manifest`,
+  `verify_server_spawn_renderer`, `diagnostic_spawn_marker`
+- Simplest approach: reuse the existing checkpoint capture pipeline with one
+  dedicated manifest and a renderer-native diagnostic marker
+- Rejected complexity: live DB adapter, new scene-test framework and production
+  spawn entity implementation before the network/gameplay milestones
+- Performance: one diagnostic checkpoint outside production runtime
+
+## Status
+
+- State: ready-for-review
+- Done: fixture-to-renderer manifest/verifier, renderer-native marker, unified
+  baseline integration, cold/warm GUI evidence, documentation and log cleanup
+- Next: integrator review, merge cleanup/handoff and M01 closeout audit
+- 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`.

+## Outcome
+
+Introduce a scene-free `StreamingFocus` value and make runtime/test streaming

+## 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

+- 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

+- Important names introduced: `StreamingFocus`, `streaming_focus_source_path`,

+- Simplest considered solution: one immutable value plus one explicit scene adapter path

+- 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,

+- 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.

 The grid therefore has no approved joint optimum. Full-frame color error continues to trade landmark framing against large terrain regions. The manifest remains unchanged. The next registration method must score an approved inn/road/tree landmark region or explicit landmark coordinates rather than the entire image.
 
+## Common landmark region — 2026-07-12
+
+The comparator accepts an optional common screen rectangle through `--region x,y,width,height`; the sweep runner exposes it as `-ComparisonRegion x,y,width,height`. Coordinates are integer pixels in the shared reference/candidate image space. Both images must have identical dimensions and the rectangle must be fully inside them. Omitting the option preserves full-frame behavior.
+
+The existing 15 WMO-ready Goldshire candidates were rescored inside `[300,100,1400,650]`, covering the reference facade/chimney and nearby trees. ROI error ranked FOV 38/yaw 10/pitch -15 first at `0.081777` with changed-pixel ratio `0.697185`. This is an interior pitch candidate and improves on the full-frame grass preference, but human inspection still rejects manifest calibration: the facade is too large, its upper part is cropped, and the rectangle retains substantial road/terrain pixels. A common rectangle is useful diagnostic weighting, not semantic landmark registration. Explicit approved landmark coordinates or a mask remain necessary.
+
 During this run the sweep orchestration was hardened in two ways: expected comparator exit code `1` is now collected through an explicit child process, and viewport dimensions are explicit. A reference/candidate `size_mismatch` now fails before ranking instead of producing an empty metric.

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

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

+| diagnostic animation phase B | `1025572c7ab9fa0d2e500ff026be46eb9c1e6e5447116dbdc3675dd5f44574ab` | Same camera three seconds later; visibly raised wing phase |

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

+# 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`.

+
+## 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, streamer and terrain probe 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.

+| 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

+
+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.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 |

+    }
+```
+
+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.

+# Player Input
+
+## Metadata
+
+| Field | Value |
+|---|---|
+| Status | Partial |
+| Target/work package | M02 / M02-GMP-INPUT-001 |
+| Owners | Gameplay input boundary; `sindo-main-codex` for current package |

+| Profiles/capabilities | Current render-sandbox defaults; `Blizzlike335` binding semantics not yet verified |
+
+## Purpose
+
+Convert remappable Godot Input Map actions into an immutable, scene-free
+`MoveIntent` that can be consumed by the current player controller and a later
+independently testable local movement controller.
+
+## Non-goals
+
+- Define authoritative server movement, prediction or reconciliation.
+- Own character transform, terrain queries, camera state or animation state.
+- Claim that the current W/S/A/D sandbox mapping exactly matches build 12340.
+- Make sprint or free flight available to the production compatibility profile;
+  their profile gate remains a later M02 package.
+
+## Context and boundaries
+
+```mermaid
+flowchart LR
+    Devices[Keyboard and mouse] --> InputMap[Godot Input Map]
+    InputMap --> Source[PlayerInputSource]
+    Source --> Intent[MoveIntent]
+    Intent --> Controller[ThirdPersonWowController]
+    Controller --> Movement[Current sandbox movement]
+    Controller --> Camera[Current camera adapter]
+```
+
+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 and vertical 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.sample_move_intent()` | Adapter method | Samples configured actions 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 |
+
+## 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 | Current scene controller | Engine-owned event | Current input dispatch only |
+| Output | `MoveIntent` | `PlayerInputSource` | Current controller; later local movement controller | Immutable caller-held value | One physics tick |
+| Output | Camera action names | `PlayerInputActions` | Current scene controller | Static constants | Process lifetime |
+
+Side effects:
+
+- `PlayerInputSource` has no side effects beyond reading current engine input.
+- The existing controller still mutates player/camera transforms and mouse mode;
+  those responsibilities are intentionally not moved by this package.
+- No filesystem, cache, network, database or renderer-resource mutation occurs.

+    Map -->|movement strengths| Source[PlayerInputSource]
+    Source -->|clamp cancel normalize| Intent[MoveIntent]
+    Intent --> Consumer[ThirdPersonWowController]
+```
+
+## Lifecycle/state
+
+The adapter is stateless. The scene composition root creates one
+`PlayerInputSource` in `_ready`; each physics tick produces a new immutable
+intent. Flight enabled/disabled state remains owned by the current sandbox
+controller and is not hidden in the input adapter.
+
+## Main sequence

+```mermaid

+    Source->>Intent: compose normalized axes and requests
+    Source-->>Player: sample_move_intent()
+    Player->>Player: update current sandbox movement 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

+
+## Configuration and capabilities
+
+| Setting/capability | Default | Profile | Runtime mutable | Effect |
+|---|---|---|---|---|
+| Forward/backward | Physical W/S | Current render sandbox | Yes, through Input Map | Produces signed forward axis |
+| Strafe left/right | Physical A/D | Current render sandbox | Yes | Produces signed right axis |
+| 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 | Sandbox debug only by intent; profile gate pending | Yes | Requests existing speed multiplier |
+| Debug flight up/down/toggle | E/Q/Space | Sandbox debug only by intent; profile gate pending | Yes | Requests existing free-flight controls |
+
+## 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,
+  default bindings, axis cancellation/clamping/normalization and debug request flags.
+- Integration/E2E: `src/tests/scenes/player_input_regression.tscn` is loaded by
+  the verifier, which drives forward, camera-zoom and immediate sandbox-flight
+  actions through the real scene controller and also rejects direct
+  physical-key polling.
+- Fidelity evidence: current sandbox defaults retain W/S/A/D, E/Q, Shift, Space,
+  right mouse and wheel bindings. This is observable-regression coverage only.
+- 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.
+- The local movement controller may replace the current scene 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 | Extract local movement controller |
+| Exact 3.3.5a default semantics | Unknown | No original-client binding fixture in this package | Capture build-12340 defaults and mouse-turn/strafe policy |
+| Production profile exclusion of sprint/flight | Partial | Debug actions are named explicitly | Add typed profile/capability gate in M02 |
+| Jump/fall/swim/fly gameplay semantics | Planned | M02 target and gameplay roadmap | Implement after terrain/movement state extraction |
+
+## Known gaps and risks
+
+- The defaults preserve the pre-M02 sandbox behavior, not verified original-client semantics.
+- Sprint and free flight are still executable by the sandbox controller until a
+  typed build-profile gate is introduced.
+- Camera input is action-mapped but camera state/collision remains in the monolithic controller.
+- There is no persisted user keybinding format or UI yet.
+
+## Source map
+
+| Path | Responsibility |
+|---|---|
+| `project.godot` | Additive default Input Map bindings |
+| `src/domain/input/move_intent.gd` | Immutable locomotion request contract |
+| `src/gameplay/input/player_input_actions.gd` | Stable project action names |

+
+## Related decisions and references
+
+- ADR: none; this implements the existing architecture and M02 seam.
+- Upstream/reference: `targets/02-player-decomposition.md`,
+  `targets/roadmap/04-gameplay-systems.md`, `docs/ARCHITECTURE.md`.

 ## Ownership, threading and resources
 
 - `StreamingWorldLoader` владеет tile states, queues, task registries, active world instances и render caches session scope.
+- Focus producers own the immutable `StreamingFocus` reference; the loader retains
+  the latest reference and converts it to `Vector3` only inside the render boundary.
 - Worker tasks не должны менять SceneTree и shared Resource concurrently.
 - Parsed/grouped results передаются обратно через guarded result queues.
 - Mesh/material/node/RID finalization выполняется main thread и ограничивается exported budgets.
 - Shutdown/map switch обязан дождаться WorkerThreadPool jobs и зарегистрированных threaded ResourceLoader requests до очистки очередей, nodes, caches и RIDs.
+- Parented streamed nodes остаются owned by SceneTree during shutdown; detached M2/WMO prototype caches are explicitly `free()`d after asynchronous work drains.
+- A temporary liquid root with no generated child geometry is explicitly freed by `ADTBuilder` instead of being returned or abandoned.
 - Cache resources считаются immutable после публикации.
