M03-RND-WMO-RENDER-RESOURCE-FINALIZER-001

Owner

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

Outcome

Move lightweight WMO render-cache terminal ResourceLoader polling, script/format validation and Resource/missing publication from the loader into one service.

Non-goals

• Change .res cache path selection or threaded request admission.
• Own WMO build permits, queues, placement state, Nodes or materialization.
• Change WMOStreamingResource.FORMAT_VERSION, fallback order or visible output.
• Combine render Resource and PackedScene finalization behind a generic callback.

Paths

• Exclusive: src/render/wmo/wmo_render_resource_finalizer.gd, src/tools/verify_wmo_render_resource_finalizer.gd, docs/modules/wmo-render-resource-finalizer.md, this claim
• Shared: loader, WMO render 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, wrong-script and stale-format Resources publish missing outcome.
• Current exact-script Resources are adopted without duplication.
• Request admission, reset/shutdown drain order and cache lifetime are unchanged.

Dependencies

• Requires: accepted WMO render Resource cache state
• Blocks: remaining loader-owned WMO orchestration/materialization cleanup

Verification

• Synthetic status/order/load/validation/adoption/source/timing contracts; adjacent WMO/renderer gates; full headless 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: ready
• Done: implementation, verification and documentation
• Next: merge and post-merge acceptance
• Blocked by:

Handoff

• Commit: a86f8f2 (render: extract WMO render resource finalizer)
• Results: finalizer PASS cases=24 iterations=1000 elapsed_ms=3.938; adjacent WMO cache/queue/planner/registry/resolver/scene-cache/shutdown checks passed; autonomous headless suite 60/60; documentation 47; coordination passed with 34 historical warnings; checkpoint dry-run 7/7.
• Remaining risks: terminal ResourceLoader polling remains a synchronous main-thread boundary; no serialized private WMO, corrupt-cache, visual, leak, 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.
