M03-RND-WMO-RUNTIME-SCENE-PREPARER-001

Owner

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

Outcome

Move cached/live WMO subtree preparation—recursive Mesh finalization, direct Occluders-child policy and recursive shadow enabling—from the loader into one stateless main-thread service.

Non-goals

  • Change scene/prototype loading, validation, placement or attachment.
  • Change WMO material refresh rules, cache versions or builder behavior.
  • Change occlusion/shadow defaults or add visibility/portal behavior.
  • Change queue, scheduler, ownership or shutdown lifecycle.

Paths

  • Exclusive: src/render/wmo/wmo_runtime_scene_preparer.gd, src/tools/verify_wmo_runtime_scene_preparer.gd, docs/modules/wmo-runtime-scene-preparer.md, this claim
  • Shared: loader, renderer module registry/specification, RENDER.md, M03 Evidence

Contracts and data

  • Cached preparation finalizes every MeshInstance3D Mesh and non-null MultiMeshInstance3D Mesh in depth-first traversal order.
  • Live preparation does not cross the runtime Mesh finalizer boundary.
  • Disabled occlusion removes only the direct child named Occluders and queues it for deletion; enabled occlusion retains it.
  • Enabled shadows recursively set every GeometryInstance3D to ON; disabled shadows preserve existing per-node values.
  • The service borrows the subtree and retains no Node or Resource.

Dependencies

  • Requires: accepted WMO runtime Mesh finalizer
  • Blocks: remaining loader-owned WMO scene/prototype orchestration cleanup

Verification

  • Synthetic cached/live traversal, exact resource/order, occluder, shadow, invalid-input, ownership, source and bounded-timing contracts; adjacent WMO, renderer, documentation and coordination gates; checkpoint dry-run.

Documentation deliverables

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

Status

  • State: active
  • Done: scope and historical path distinction identified
  • Next: implement and verify subtree preparation delegation
  • Blocked by:
