M03-RND-M2-STATIC-BUILD-RESOURCE-OBSERVER-001

Owner

• Agent ID: sindo-main-codex
• Target: M03 Renderer Facade and Safe Extraction
• Branch: work/sindo-main-codex/m03-m2-static-build-resource-observer
• Worktree: C:\Users\sindo\open-wc-worktrees\m03-m2-static-build-resource-observer

Outcome

Move static M2 build cache lookup, threaded request selection and terminal missing transition from the loader into a service that fills M2BuildResourceSnapshot.

Non-goals

• Move animation/native prototype observation or finalize drains.
• Own/free Meshes, Nodes or cache entries.
• Change path candidate order, GLB filtering, retry behavior, permits or visuals.
• Change cache formats, profiles or batching.

Paths

• Exclusive: src/render/m2/m2_static_build_resource_observer.gd, src/tools/verify_m2_static_build_resource_observer.gd, docs/modules/m2-static-build-resource-observer.md, this claim
• Shared: loader, M2 snapshot/dispatch/pipeline/cache specs and verifiers, world renderer, module registry, RENDER and M03 Evidence

Contracts and data

• Cached Mesh wins; terminal missing returns missing; existing pending request waits.
• Candidate order remains normalized/lowercase nested then basename per extension.
• .tscn precedes .glb; pivot-prefix GLB is skipped for static build.
• Successful/ERR_BUSY request is remembered; no usable candidate marks missing.
• Snapshot adopts exact Mesh/missing result; service never frees engine objects.

Dependencies

• Requires: accepted resource snapshot 032a256
• Blocks: remaining animated resource observer extraction

Verification

• Synthetic cache/pipeline/snapshot lifecycle, path order, source boundaries and timing; adjacent M2 and 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.
