 - 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.

+- Target: M01
+- Program: FND/QAR
+- 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.

+## Verification
+
+- Commands: identity contract/boundary verifier, dependency search,

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

+ADT tile/chunk.
+
+## Non-goals

+- Connecting to a live AzerothCore or TrinityCore database.

+  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`,

+- Fidelity: source remains AzerothCore revision
+  `68fcf0098b16388093989627f37be530fc91f07d`; server
+  `(-8949.95,-132.493,83.5312)` maps to Godot

+  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`.

+# 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.

+## Public API
+
+| Symbol | Kind | Purpose | Thread/lifetime | Errors |
+|---|---|---|---|---|
+| `ContentId` | Immutable value | Stable authored identity as canonical lowercase UUID text | Any thread; persisted content lifetime | `is_valid()` reports malformed shape |
+| `ContentId.equals` | Pure method | Value equality across references | Call duration | Null compares false |
+| `ContentId.to_key` | Pure method | Canonical serialization/dictionary key | Stable across schema lifetime | Caller must validate first |
+| `EntityId` | Immutable value | Positive session-local runtime sequence | One runtime session | `is_valid()` rejects zero/negative |
+| `EntityId.equals` | Pure method | Equality within an explicitly shared session | Call duration | Cross-session comparison is a caller error |
+| `EntityId.to_debug_key` | Pure method | Non-persistent diagnostic label | Session/log lifetime | Must not be serialized as content |
+| `WowGuid` | Immutable value | Opaque unsigned high/low wire words | Packet/replay/entity mapping lifetime | `has_valid_word_ranges()` reports overflow |
+| `WowGuid.is_empty` | Pure method | Detect all-zero wire sentinel | Call duration | Does not assign semantic meaning |
+| `WowGuid.to_hex_string` | Pure method | Sixteen-digit diagnostic/replay key | Wire/replay lifetime | Caller validates ranges first |

+    ContentSource[Authored document] -->|UUID text| ContentId
+    ServerRow[Backend table row] -->|adapter + table + entry| ServerEntryId
+    Packet[World packet] -->|high/low wire words| WowGuid

+    WowGuid --> RuntimeMap[Explicit runtime mapping]
+    EntityId --> RuntimeMap
+    DeployMap --> Snapshot[Versioned snapshot/change set]
+    RuntimeMap --> WorldState[Session world state]
+```
+
+## Lifecycle/state
+
+```mermaid
+stateDiagram-v2
+    state ContentIdentity {
+        [*] --> Parsed
+        Parsed --> Persisted: valid ContentId
+        Persisted --> Referenced
+    }
+    state RuntimeIdentity {
+        [*] --> Allocated
+        Allocated --> Active
+        Active --> Released: session owner removes entity
+        Released --> [*]

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

 ## Steps

- [ ] Создать domain/value-object слой без `Node`/`Resource` dependencies.
- [ ] Определить canonical WoW, Godot, ADT tile/chunk и local coordinate types.
- [ ] Реализовать единственный `CoordinateMapper` для position и orientation.
- [ ] Собрать golden points из ADT, server spawn и оригинального клиента.
- [ ] Ввести `StreamingFocus` вместо неявной зависимости от active Camera3D.
- [ ] Ввести stable `ContentId`, `EntityId` и отличить их от WoW GUID/server entry.
- [ ] Запретить ручные axis conversion через code review rule/test search.
