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.
