 ## Status
 
-- State: claimed
+- State: handoff
-- Done: scope, formulas and ownership published
+- Done: immutable policy, pure planner, both loader call sites, regressions and docs
-- Next: implement policy/planner, migrate one call site, tests and docs
+- Next: milestone integrator merge and asset-backed performance acceptance later in M03

 ## Handoff
 
-- Commit:
+- Commit: `eb94cfc` (`refactor(M03): extract terrain chunk LOD planner`)
-- Results:
+- Results: dedicated contract PASS (`cases=7`, `iterations=250`, `12.726 ms`);
-- Remaining risks:
+  cache/facade/internal-access/manifest/shutdown/scheduler/streaming-focus/
-- Documentation updated:
+  streaming-planner/ground/terrain-query/coordinate regressions PASS; editor parse
+  has no script errors; documentation and coordination gates PASS; checkpoint
+  dry-run planned `7/7` entries with expected missing-private-corpus diagnostics
+- Remaining risks: asset-backed p95/p99 and visual acceptance remain pending;
+  terrain state, queue, quality-upgrade and finalization ownership remains in loader
+- Documentation updated: `terrain-chunk-lod-planner.md`, module registry,
+  `world-renderer.md`, `RENDER.md`, inline public API documentation and data-flow,
+  lifecycle and sequence diagrams
