docs(M03): hand off M2 mesh load pipeline state

Work-Package: M03-RND-M2-MESH-LOAD-PIPELINE-001
Agent: sindo-main-codex
Tests: 34 headless regressions, documentation/coordination gates and checkpoint dry-run pass
Fidelity: lifecycle extraction only; asset-backed visual parity remains unclaimed

 ## Status
 
-- State: claimed
-- Done: all request/finalize/metric/wait/reset sites identified
-- Next: implement state holder, migrate loader adapters, verify and document
+- State: ready
+- Done: state holder, loader adapters, contract verifier and required documentation
+- Next: integrator merge and post-merge smoke

 ## Handoff
 
-- Commit:

-- Documentation updated:
+- Commit: `82df7a5`
+- Results: 34 headless contract regressions pass; dedicated pipeline state
+  verifier passes 100-by-256 transitions in 100.273 ms; documentation and
+  coordination gates pass; checkpoint dry-run passes 7/7.
+- Remaining risks: no private asset traversal, leak/descriptor-pressure or
+  original-client visual comparison; ResourceLoader I/O and Mesh cache/finalizer
+  ownership remain in `StreamingWorldLoader` by design.
+- Documentation updated: inline API; `m2-mesh-load-pipeline-state.md` with
+  data-flow, state, sequence and dependency diagrams; module registry,
+  `world-renderer.md` and `RENDER.md`.
