+<!-- OPENWC_CLAIM:M03-RND-M2-BUILD-DISPATCH-PLANNER-001:sindo-main-codex:2026-07-20 -->
+
+## Owner
+
+- Agent ID: `sindo-main-codex`
+- Target: M03 Renderer Facade and Safe Extraction
+- Branch: `work/sindo-main-codex/m03-m2-build-dispatch-planner`
+- Worktree: `C:\Users\sindo\open-wc-worktrees\m03-m2-build-dispatch-planner`
+
+## Outcome
+
+Extract the pure M2 build-step dispatch decision from the loader while preserving
+animation-wait priority, static-resource retry, missing-model advancement and
+exact permit/cursor behavior.
+
+## Non-goals
+
+- Move ResourceLoader I/O, path lookup, cache state or retry ownership.
+- Create/free Nodes, Meshes, MultiMeshes or animated instances in the planner.
+- Change batch sizing, queue ordering, transforms, visuals or cache versions.
+- Add spatial-cell batching or new diagnostics/profile settings.
+
+## Paths
+
+- Exclusive: `src/render/m2/m2_build_dispatch_planner.gd`,
+  `src/tools/verify_m2_build_dispatch_planner.gd`,
+  `docs/modules/m2-build-dispatch-planner.md`, this claim
+- Shared/hotspots: `src/scenes/streaming/streaming_world_loader.gd`, M2 build/
+  queue/materializer/cache verifiers and specs, `docs/modules/world-renderer.md`,
+  `docs/modules/README.md`, `RENDER.md`, `targets/03-renderer-facade.md`
+- Generated/ignored: `.godot`, native DLL, generated resources/caches and proprietary corpus
+
+## Contracts and data
+
+- Pending animation request wins before empty/animated/static decisions.
+- Positive batch with animated prototype selects animated materialization.
+- Positive static batch selects prepared Mesh, waits when unresolved, and advances
+  without materialization only when the model is terminally missing.
+- Zero/non-positive batch advances without materialization.
+- Planner returns a fresh action plan and owns no state or engine reference.
+
+## Dependencies
+
+- Requires: accepted typed M2 build queue on master `c74b90a`
+- Blocks: extracting stateful M2 resource readiness/dispatch orchestration
+- External state: cache lookups, requests and engine lifetime remain loader APIs
+
+## Verification
+
+- Commands: dedicated action-priority/matrix/fresh-result/source/timing verifier;
+  M2 queue/planner/materializer/cache/prototype/shutdown/facade/internal-access/
+  manifest regressions; documentation, coordination and checkpoint dry-run gates
+- Fixtures: scalar availability and terminal-state combinations only
+- Fidelity evidence: exact existing branch priority and retry/advance behavior
+- Performance budget: 20,000 pure dispatch plans under one second
+
+## Documentation deliverables
+
+- Inline API docs
+- Module spec with inputs/outputs, ownership and source map
+- Data-flow, lifecycle/state, sequence and dependency diagrams
+- Adjacent M2 build/world-renderer/module-registry/RENDER updates
+
+## Simplicity and naming
+
+- Important name: `M2BuildDispatchPlanner`
+- Simplest solution: one stateless RefCounted with explicit action constants
+- Rejected complexity: callbacks, signals, cache references and generic state machine
+- Unavoidable complexity: animation-pending priority precedes every other action
+- Measured optimization evidence: bounded synthetic decision loop
+
+## Status
+
+- State: active
+- Done: contract and ownership boundary
+- Next: implementation, verification and documentation
+- Blocked by:
