+# M03-RND-WMO-RENDER-BUILD-QUEUE-001 — WMO render build queue
+
+<!-- OPENWC_CLAIM:M03-RND-WMO-RENDER-BUILD-QUEUE-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-render-build-queue`
+- Lease expires UTC: 2026-07-20
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Extract typed lightweight-WMO render build jobs and their FIFO key queue from
+the loader while leaving all engine-object destruction and materialization in
+the loader.
+
+## Non-goals
+
+- Queue-free Nodes or free Resources/RIDs.
+- Move material refresh, Node creation, editor ownership or budget permits.
+- Change duplicate enqueue, stale-key cleanup, cancel or clear ordering.
+- Change placement, cache loading/versioning, transforms, shadows or visibility.
+- Claim asset-backed WMO fidelity, leak acceptance or traversal p95/p99.
+
+## Paths
+
+- Exclusive: `src/render/wmo/wmo_render_build_job.gd`,
+  `src/render/wmo/wmo_render_build_queue.gd`,
+  `src/tools/verify_wmo_render_build_queue.gd`,
+  `docs/modules/wmo-render-build-queue.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`,
+  `docs/modules/wmo-render-build-step-planner.md`,
+  `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
+
+- Typed job: placement key, strong Node3D/Resource references and two cursors
+- FIFO queue preserves duplicate key append and first-occurrence erase behavior
+- Stale front keys remain observable for loader-compatible pop-and-continue
+- Cancel releases the keyed job reference and first queued key only
+- Clear releases every job/key reference idempotently; never frees engine objects
+- Loader retains validity checks, planner invocation, cursor adoption,
+  materialization, permits, cancellation reactions and Node destruction
+- Cache/schema/coordinate/profile versions: unchanged
+
+## Dependencies
+
+- Requires: current master `1e740aa`, accepted WMO build step planner
+- Blocks: further WMO cache/load and materialization decomposition
+- External state: none; verification uses synthetic Node3D/Resource instances
+
+## Verification
+
+- Commands: dedicated invalid/FIFO/duplicate/stale/cursor/cancel/clear/
+  diagnostics/source/timing verifier; WMO planner/registry/resolver/material/
+  shutdown plus M2/terrain/facade/internal-access/manifest/scheduler/streaming/
+  coordinate/docs/coord gates
+- Fidelity evidence: exact current queue/dictionary behavior preserved
+- Performance budget: 100 cycles over 256 jobs under 1 second
+
+## Documentation deliverables
+
+- Inline job/queue API documentation
+- New module spec with inputs/outputs, data flow, state/sequence, ownership,
+  threading, failure/recovery, performance/fidelity limits and source map
+- Build-step planner, renderer module registry, world renderer and RENDER updates
+
+## Simplicity and naming
+
+- Important names: `WmoRenderBuildJob`, `WmoRenderBuildQueue`
+- Simplest solution: one typed record plus Dictionary/Array queue composition
+- Rejected complexity: generic job scheduler, signals, callbacks, mutexes,
+  Resources as job records or engine lifetime callbacks
+- Unavoidable complexity: duplicate keys can intentionally leave stale entries
+- Measured optimization evidence: bounded synthetic enqueue/cancel/clear loop
+
+## Status
+
+- State: claimed
+- Done: ownership, duplicate/stale and engine-lifetime boundary published
+- Next: implement queue/job, migrate loader state, tests and docs
+- Blocked by:
