## Ownership
- Target: M01
- Program: FND
- Owner/Agent ID: sindo-main-codex
- Branch: `work/sindo-main-codex/m01-coordinate-mapper`
- Lease expires UTC: 2026-07-15
- Integrator: M01 milestone integrator
## Outcome
Introduce scene-free value objects for canonical WoW, server, ADT placement,
ADT tile/chunk/local and Godot world coordinate spaces, plus the single pure
`CoordinateMapper` contract for position and world-yaw conversions.
## Non-goals
- Migrating `StreamingWorldLoader`, native parsers, sky, player or renderer code.
- Defining model-specific MDDF/MODF Euler rotation corrections.
- Introducing `StreamingFocus`, typed IDs or a test framework dependency.
- Claiming visual parity from arithmetic round trips.
## Paths
- Exclusive: `src/domain/coordinates/**`, `src/tools/verify_coordinate_mapper.gd`,
`docs/modules/coordinate-mapping.md`, `docs/adr/0001-canonical-world-coordinates.md`
- Shared/hotspots: `docs/modules/README.md`, this claim
- Generated/ignored: Godot import metadata and local test output
## Contracts and data
- Public API/events: immutable coordinate value objects and pure mapper methods
- Schema/format version: no persisted format; contract version 1 in module docs
- Migration/compatibility: additive contract; existing renderer conversions remain
unchanged until a later consumer migration package
- Consumers: future renderer, network, gameplay and server-data adapters
- Rollout order: contract and fixtures first, then native/parser and renderer consumers
## Dependencies
- Requires: merged M00 build 12340 coordinate calibration evidence
- Blocks: M01 renderer coordinate migration and `StreamingFocus`
- External state: no proprietary inputs; reference formulas are source-only evidence
## Verification
- Commands: headless coordinate contract probe, headless project load,
coordination and documentation gates
- Fixtures: five build 12340 camera points, ADT map center/edge/boundary points,
server/ADT/Godot round trips and yaw normalization cases
- Fidelity evidence: M00 observed build 12340 positions plus independent
OpenRealm/WoWee and TrinityCore grid formulas
- Performance budget: constant-time scalar arithmetic with no allocation beyond result values
## Documentation deliverables
- Inline public API docs: every public value object and mapper method
- Module specification: purpose, public API, inputs/outputs, ownership, errors and source map
- Data-flow diagram: server/ADT/canonical/Godot mappings
- Dependency diagram: canonical contract consumers and forbidden scene dependency
- Sequence/state diagrams: not applicable; mapper is synchronous and stateless
- ADR: coordinate axes, units, tile indexing and compatibility rollout
## Simplicity and naming
- Important names introduced: `CanonicalWowWorldPosition`, `ServerWorldPosition`,
`AdtPlacementPosition`, `AdtTileCoordinate`, `AdtChunkCoordinate`,
`AdtTileLocalPosition`, `GodotWorldPosition`, `WorldYaw`, `CoordinateMapper`
- Simplest considered solution: scalar immutable value objects and one pure mapper
- Rejected complexity/abstractions: generic vector-space framework, matrices,
dependency injection and a third-party test framework
- Unavoidable complexity and justification: distinct source spaces prevent silent axis swaps
- Measured optimization evidence: not applicable
## Status
- State: ready-for-review
- Done: repository/reference audit, ADR, immutable value objects, pure mapper,
build 12340/boundary/yaw fixtures, module specification and repository gates
- Next: integrator review and merge before renderer/native consumer migration
- Blocked by:
## Handoff
- Commit: `f45695c`
- Branch: `work/sindo-main-codex/m01-coordinate-mapper`
- Outcome: additive contract for canonical/server/ADT/Godot positions, ADT
tile/chunk/local ownership and world-facing yaw; no existing consumer changed
- Public contracts: contract version 1 documented in
`docs/modules/coordinate-mapping.md`; no persisted schema or cache change
- Verification: coordinate mapper PASS (5 golden points, 8 tile boundaries,
5 yaw cases); M00 coordinate calibration PASS (5 points, maximum error
`0.000015`); renderer manifest, coordination, documentation, dependency and
whitespace checks passed; headless project load completed with expected
missing proprietary-data diagnostics in the isolated worktree
- Fidelity: observed build 12340 positions match within `0.002` yard; formulas
cross-checked against TrinityCore, OpenRealm and WoWee; visual parity is not claimed
- Migration/rebuild: none for this additive package; consumers migrate only
after merge and must preserve renderer checkpoints
- Remaining risks: native loaders and renderer still use manual conversions;
MDDF/MODF Euler mapping is intentionally unresolved; server-spawn integration
and finite-value adapter validation remain later M01 packages
- Recommended merge order: this contract first, coordinate fixtures/server-spawn
audit second, renderer/native consumers third, manual-conversion search gate last
- Documentation: ADR 0001; coordinate-mapping module spec with data-flow and
dependency diagrams; inline API documentation on all public symbols

# ADR 0001: Canonical world coordinate contract
- Status: Accepted for M01 contract implementation
- Date: 2026-07-13
- Work package: `M01-FND-COORDS-001`
- 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.X / ADT_TILE_SIZE_YARDS)
tileY = floor(32 - canonical.Y / 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. An `AdtChunkCoordinate` uses `chunk_x` south and `chunk_y`
east, 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.
## 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.
- Existing native/parser and renderer conversions remain unchanged until
separate consumer migration packages merge after this contract.
- Manual axis conversions become review/test violations once migration is
complete; this ADR alone does not delete compatibility paths.
- 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.
- World-yaw normalization and round-trip cases cover cardinal angles and wrap.

## 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 | 1 | All | No | Axis, unit and boundary semantics 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
This package adds no persisted format, cache or migration. 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`.
- Integration/E2E: consumer migration and `StreamingFocus` packages remain pending.
- Fidelity evidence: five build-12340 camera positions from the M00 manifest map
within `0.002` yard; 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 and five M00 golden points | Migrate producers/consumers |
| ADT placement mapping | Implemented | Synthetic/direct round-trip fixtures | Compare native parsed placements during migration |
| ADT tile/local/chunk ownership | Implemented | Center, extent, tile and chunk boundary fixtures | Migrate streaming names/ownership |
| World-facing yaw mapping | Implemented | Cardinal/wrap round-trip fixtures | Placement Euler remains separate |
| Scene-free production contract | Implemented | Source boundary and headless test | Add dependency search gate later in M01 |
| Visual/server-spawn integration | Planned | M01 target criteria | Add golden server spawn after adapter migration |
## Known gaps and risks
- Existing native loaders and renderer scripts still contain manual conversions.
- Current `StreamingWorldLoader` tile names may represent Godot X/Z ordering rather
than ADT filename X/Y; migration must preserve visible baseline behavior.
- 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.

## Evidence
- Date: 2026-07-10
- Revision/worktree: `93bfe11` + worktree baseline changes.
- Commands: `.\tools\run_render_baseline.ps1 -DryRun -WaitSeconds 0.1 -MeasureSeconds 0.1 -Output user://render_baseline_runner_test`; `.\tools\run_render_baseline.ps1 -Output user://render_baseline_m00_2026-07-10 -CacheState existing`.
- Results: headless load, renderer material smoke, M2 unique-id dedupe and manifest contract passed. Full run produced 14 PNGs and 14 result records for 7 cold/warm checkpoints. Actual renderer was Godot 4.6.1, Vulkan Forward+, NVIDIA RTX 5070, 1280x900, High profile, with all seven cache families present. Cold p95 range was 31.585..86.537 ms with max hitch 258.456 ms; warm p95 range was 18.824..38.085 ms with max hitch 163.363 ms. The final streaming snapshots had an empty tile queue. Report: `user://render_baseline_m00_2026-07-10/report.json`.
- Fidelity comparison: fixed positions/time/profile and current visual gaps are recorded, but no approved paired screenshots from the original WoW 3.3.5a build 12340 were available. This baseline does not claim parity.
- Changed files: `RENDER.md`, `docs/RENDER_BASELINE.md`, `src/scenes/streaming/streaming_world_loader.gd`, `src/tools/capture_render_checkpoints.gd`, `src/tools/render_baseline_manifest.json`, `src/tools/verify_render_baseline_manifest.gd`, `tools/run_render_baseline.ps1`, `targets/00-render-baseline.md`.
- Remaining risks: original-client paired comparison is still required before DONE; D3D12 descriptor heap creation failed and the measured run fell back to Vulkan; shutdown reported leaked renderer RIDs/resources; current captures intentionally preserve visible terrain/placement/material/animation gaps, including the synthetic native animated M2 probe; perceptual image diff/tolerance is documented but not automated yet.
- Date: 2026-07-13
- Revision/worktree: merged M00 implementation through `f19c0c4`; closeout worktree `work/sindo-main-codex/m00-integrator-closeout`.
- Commands: `.\tools\run_render_baseline.ps1 -Output user://render_baseline_m00_complete_2026-07-13 -CacheState existing -WaitSeconds 8 -MeasureSeconds 0.5 -ReferenceCheckpointDirectory .\sources\OpenWCReferenceCheckpoints -VisualComparisonReport user://render_baseline_m00_complete_2026-07-13/visual_comparison.json -VisualComparisonWidth 2560 -VisualComparisonHeight 1440`; `.\tools\run_render_baseline.ps1 -DryRun -WaitSeconds 0.1 -MeasureSeconds 0.1 -Output user://render_baseline_m00_post_merge`; `.\tools\verify_coordination.ps1`; `.\tools\verify_documentation.ps1`.
- Results: the final GUI run produced fourteen cold/warm captures for seven checkpoints and all seven required coverage categories, with `compared=14` and `missing=0`. The post-merge dry-run passed project load, material, M2 unique-id dedupe, runtime-cache shutdown, manifest and five-point coordinate calibration checks. Coordination and documentation gates passed. Renderer shutdown follow-up removed retained Node/resource/RID diagnostics in focused and seven-checkpoint GUI runs.
- Fidelity comparison: private original-client WoW 3.3.5a build 12340 references cover terrain, ADT boundary, dense M2, large WMO, liquid, animated M2 and sky transition. Every measured pair exceeds the strict visual tolerance and is recorded as a current gap rather than parity. Sky framing is approximately paired; animated M2 is asset-paired but placement-unpaired because the OpenWC Goldshire probe is synthetic. Full metrics and provenance are recorded in `docs/M00_FINAL_PAIRED_EVIDENCE.md`.
- Changed files: `RENDER.md`, `docs/RENDER_BASELINE.md`, `docs/M00_FINAL_PAIRED_EVIDENCE.md`, `docs/modules/world-renderer.md`, renderer baseline scripts/verifiers, manifest/capture tooling, streaming shutdown ownership and M00 coordination claims.
- Remaining risks: renderer parity is not claimed; documented terrain/material/placement/animation/lighting/liquid/culling gaps remain future renderer work. D3D12 descriptor heap creation can fall back to Vulkan. Godot can emit a timing-dependent anonymous zero-reference `RefCounted` teardown warning without retained Node/resource/RID ownership.

- Runtime streaming, terrain quality, MultiMesh M2, WMO caches, liquids, sky и character experiments находятся в рабочем состоянии, но сосредоточены в крупных orchestration scripts.
- Renderer baseline M00 создан; до `DONE` не хватает paired comparison с оригинальным клиентом и закрытия известных diagnostic gaps.
- Renderer baseline M00 завершён: paired comparison с оригинальным клиентом записывает измеренные gaps без заявления parity, а обязательные diagnostic gaps закрыты или явно классифицированы. Текущая работа M01 вводит coordinate и architecture seams.
- Gameplay domain, network protocol, production UI/Lua, audio orchestration и server adapters в основном предстоит реализовать.
- Editor plugin пока решает extraction/preview задачи, но не является полноценной authoring platform.
