 ## Status
 
-- State: active
-- Done: claim and isolated worktree created
-- Next: implement pure contracts, migrate runtime/editor refresh, verify
+- State: ready-for-review
+- Done: extracted immutable policy/plan and pure planner, migrated runtime/editor
+  target refresh, added behavior/dependency/performance coverage and module docs
+- Next: M03 integrator reviews and merges `e887c3b`

+- Commit: `e887c3b`
+- Results: runtime/editor wanted and retained ADT sets plus boundary-prefetch
+  centers are calculated by scene-free `StreamingTargetPlanner`; streamer keeps
+  queue ordering, LOD/detail state, jobs, caches, nodes and RIDs.
+- Verification: planner `cases=5 iterations=250 average_ms=1.765`; facade
+  `delegation=3 runtime_scenes=2 tools=3`; focus `contract=1 runtime_scenes=2
+  capture_tools=3`; coordinate boundary `files=109 consumers=6`; renderer
+  manifest `checkpoints=7 coverage=7 caches=7`; shutdown ownership passed;
+  documentation, coordination and diff gates passed.
+- Fidelity: center/corner/catalog/clamp/editor fixtures preserve the extracted
+  formulas; seven-checkpoint dry-run retained all plans. No radius, threshold,
+  load priority, cache version, placement, material, animation or visibility
+  rule changed. No build-12340 parity claim is added.
+- External/local inputs: ignored native DLL and generated ADT resource scripts
+  were copied from master for worktree smoke only. Proprietary ADT and character
+  assets were unavailable, so the dry-run emitted expected degraded-data diagnostics.
+- Remaining risks: exact p95/p99 impact still needs an asset-backed baseline;
+  pathological custom radii are not benchmarked; tile-key strings remain the
+  existing internal catalog representation; queue/LOD application remains monolithic.
+- Documentation updated: new planner module spec with API/input/output/data-flow/
+  sequence/ownership/recovery/performance/source-map sections; world renderer,
+  coordinate mapping, module registry and renderer implementation notes updated.
