+# M03-RND-WMO-PLACEMENT-RESOLVER-001 — WMO placement resolver
+
+<!-- OPENWC_CLAIM:M03-RND-WMO-PLACEMENT-RESOLVER-001:sindo-main-codex:2026-07-20 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-wmo-placement-resolver`
+- Lease expires UTC: 2026-07-20
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Extract pure WMO cache-path normalization, placement identity and world-transform
+resolution from the loader into a scene-free service.
+
+## Non-goals
+
+- Change WDT/ADT coordinate conversion or WMO placement values.
+- Own WMO registry references, tile lifecycle, jobs, queues or retries.
+- Load cached/live WMO resources or validate cache format versions.
+- Create Nodes, Mesh/MultiMesh, materials or RIDs.
+- Change portal/room/material/occlusion behavior or claim WMO parity.
+
+## Paths
+
+- Exclusive: `src/render/wmo/wmo_placement_resolver.gd`,
+  `src/tools/verify_wmo_placement_resolver.gd`,
+  `docs/modules/wmo-placement-resolver.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,
+  `docs/modules/world-renderer.md`, `docs/modules/README.md`, `RENDER.md`,
+  `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated ADT/WMO resources, caches
+  and proprietary renderer corpus
+
+## Contracts and data
+
+- `normalize_relative_path`: replace backslashes, lowercase entire cache key
+- `resolve_unique_key`: positive `unique_id` becomes `uid:<decimal>`; otherwise
+  preserve `tile:<tile-key>:<placement-index>` fallback
+- `resolve_world_transform`: defaults position/rotation to zero and scale to one;
+  compose the same Godot Euler basis and un-clamped uniform scale
+- Three transform consumers: render-cache root, cached scene and live prototype
+- Cache/schema/coordinate/profile versions: unchanged
+
+## Dependencies
+
+- Requires: current master `4f40c77`
+- Blocks: WMO registry/build decomposition
+- External state: none; tests use synthetic paths and placement dictionaries
+
+## Verification
+
+- Commands: dedicated path/identity/default/rotation/scale/source and bounded
+  timing verifier; M2/terrain/facade/internal-access/manifest/shutdown/scheduler/
+  streaming/coordinate/documentation/coordination gates
+- Fidelity evidence: exact normalization, identity and property-transform rules
+  moved unchanged
+- Performance budget: constant-time string/value math; no Node, Resource, RID,
+  task, queue, mutex, cache or file access
+
+## Documentation deliverables
+
+- Inline resolver API documentation
+- New module spec with inputs/outputs, data-flow, lifecycle, ownership, failure,
+  performance, fidelity limitations and source map
+- Renderer/module registry and `RENDER.md` updates
+
+## Simplicity and naming
+
+- Important name: `WmoPlacementResolver`
+- Simplest solution: one stateless service with three explicit pure queries
+- Rejected complexity: placement class hierarchy, generic model resolver,
+  Resources, strategies, callbacks or registry framework
+- Unavoidable complexity: raw placement Dictionary remains parser boundary
+- Measured optimization evidence: bounded synthetic resolver loop
+
+## Status
+
+- State: claimed
+- Done: exact rules, consumers and ownership boundary published
+- Next: implement resolver, migrate adapters, tests and docs
+- Blocked by:
