 ## Status
 
-- State: claimed
-- Done: scope, ordering and ownership published
-- Next: implement planner, migrate chunk queue calculation, tests and docs
+- State: handoff
+- Done: pure planner, loader queue adoption, semantic/timing regressions and docs
+- Next: milestone integrator merge and asset-backed performance acceptance later in M03
 - Blocked by:
 
 ## Handoff
 
-- Commit:
-- Results:
-- Remaining risks:
-- Documentation updated:
+- Commit: `f800e11` (`refactor(M03): extract terrain chunk queue planner`)
+- Results: dedicated contract PASS (`cases=8`, `iterations=100`, `235.096 ms`);
+  LOD/cache/facade/internal-access/manifest/shutdown/scheduler/streaming/focus/
+  ground/terrain-query/coordinate regressions PASS; internal inventory remains
+  `42`; editor parse has no script errors; documentation/coordination/diff gates
+  PASS; checkpoint dry-run planned `7/7` entries with expected missing-private-
+  corpus diagnostics
+- Remaining risks: planner adds a second linear tile-state pass; asset-backed
+  p95/p99 and visual acceptance remain pending; queue drains, terrain state and
+  Mesh/Node/RID finalization remain loader-owned
+- Documentation updated: `terrain-chunk-geometry-queue-planner.md`, module
+  registry, `world-renderer.md`, `RENDER.md`, inline API documentation and
+  data-flow/lifecycle/sequence diagrams
