M03-RND-M2-ANIMATION-RESOURCE-FINALIZER-001

Owner

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

Outcome

Move cached animated M2 ResourceLoader status polling, terminal Resource load, candidate finalization, prototype/static-only adoption and success diagnostics from the loader into a dedicated two-phase finalization service.

Non-goals

• Change cached animation eligibility, request admission or native-first order.
• Move material-prototype lookup, permit ownership, playback or materialization.
• Change ResourceLoader status order, cache formats, profiles or visible output.
• Generalize static and animated ResourceLoader paths behind callbacks/frameworks.

Paths

• Exclusive: src/render/m2/m2_animation_resource_finalizer.gd, src/tools/verify_m2_animation_resource_finalizer.gd, docs/modules/m2-animation-resource-finalizer.md, this claim
• Shared: loader, animation pipeline/scene finalizer/prototype cache/cached observer/world-renderer specs and verifiers, module registry, RENDER.md, M03 Evidence

Contracts and data

• Pending request snapshots are polled in existing Dictionary insertion order.
• Empty Resource paths are discarded and marked static-only immediately.
• Only LOADED/FAILED statuses move into completion-order finalize FIFO.
• One permit processes one popped terminal record, including skipped/stale records.
• Existing prototype/static-only state suppresses terminal Resource loading.
• LOADED Resource is instantiated before material-prototype lookup is requested.
• Candidate repair/finalize/adoption and exact M2_ANIM_CACHE debug fields remain.
• Rejected candidates are released by the existing animated scene finalizer.

Dependencies

• Requires: accepted animation pipeline, scene finalizer, cached/native observers
• Blocks: remaining loader-owned M2 material-prototype lookup and action execution

Verification

• Synthetic polling/status/FIFO/skip/load/candidate/repair/adoption/log/source and timing contracts; adjacent M2/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.
