M03-RND-WMO-SCENE-RESOURCE-FINALIZER-001

Owner

• Agent ID: sindo-main-codex
• Target: M03 Renderer Facade and Safe Extraction
• Branch: work/sindo-main-codex/m03-wmo-scene-resource-finalizer
• Worktree: C:\Users\sindo\open-wc-worktrees\m03-wmo-scene-resource-finalizer

Outcome

Move cached WMO PackedScene terminal ResourceLoader polling, probe validation, probe lifetime and scene/missing publication from the loader into one service.

Non-goals

• Change .tscn path selection, file-size admission or request start behavior.
• Own live fallback, placement/build jobs, attached Nodes or scheduler permits.
• Change WMOBuilder cache metadata/version rules or visible output.
• Merge PackedScene and lightweight render Resource finalization generically.

Paths

• Exclusive: src/render/wmo/wmo_scene_resource_finalizer.gd, src/tools/verify_wmo_scene_resource_finalizer.gd, docs/modules/wmo-scene-resource-finalizer.md, this claim
• Shared: loader, WMO scene cache state spec/verifier, world renderer registry/spec, RENDER.md, M03 Evidence

Contracts and data

• Pending requests are polled in detached Dictionary insertion order.
• Only LOADED/FAILED statuses complete requests.
• Failed, null, non-PackedScene, non-Node3D and stale scenes publish missing.
• Accepted PackedScenes retain exact Resource identity.
• Validation instantiates once and releases accepted/rejected Node3D probes once.
• Admission, oversize logging, live fallback and shutdown order are unchanged.

Dependencies

• Requires: accepted WMO scene Resource cache state
• Blocks: remaining loader-owned WMO live fallback/materialization cleanup

Verification

• Synthetic status/order/type/probe/validation/lifetime/adoption/source/timing contracts; adjacent WMO/renderer gates; full suite and checkpoint dry-run.

Documentation deliverables

• Inline API docs; module API/I/O/ownership; data-flow/state/sequence/dependency diagrams; adjacent renderer docs and M03 Evidence.

Status

• State: accepted
• Done: implementation, verification and documentation
• Next: next unclaimed M03 renderer extraction package
• Blocked by:

Handoff

• Commit: 7779e9e (render: extract WMO scene resource finalizer)
• Results: finalizer PASS cases=26 iterations=1000 elapsed_ms=4.186; adjacent WMO scene/render cache/finalizer/queue/planner/registry/resolver and shutdown checks passed; autonomous headless suite 61/61; documentation 48; coordination passed with 34 historical warnings; checkpoint dry-run 7/7.
• Remaining risks: PackedScene probe validation remains synchronous main-thread work; no serialized private WMO stale/oversize, long leak, visual, descriptor-pressure or p95/p99 evidence was added.
• Documentation updated: new full module specification with API/I/O and data-flow/state/sequence/dependency diagrams; adjacent WMO cache/world-renderer specs, module registry, RENDER.md and M03 Evidence.
• Merge: 6a0f9bd (merge: WMO scene resource finalizer)
• Post-merge: finalizer PASS cases=26 iterations=1000 elapsed_ms=3.970; WMO scene/render cache/finalizer/queue/planner/registry/resolver/shutdown, facade, internal-access 30, manifest and checkpoint dry-run 7/7, documentation 48 and coordination gates passed.
