+## Handoff
+
+- Commit: `47dec6c`
+- Branch: `work/sindo-main-codex/m01-coordinate-boundary-gate`
+- Outcome: all audited GDScript world/tile conversions in sky, streaming,
+  player spawn/ground sampling and terrain probes route through typed
+  `CoordinateMapper` boundaries. A repository scan rejects new manual
+  world-center, legacy axis-conversion, world-to-tile, tile-local and
+  tile-center formulas.
+- Contract/schema: additive `godot_to_adt_tile`,
+  `godot_to_adt_tile_local` and `adt_tile_local_to_godot` APIs; no persisted
+  format, cache version or renderer radius changes.
+- Verification: CoordinateConversionBoundaries PASS (`83` files, one native
+  boundary, one independent oracle, four consumers, six classifier guards);
+  CoordinateMapper PASS (`5` golden points, `8` tile boundaries, `2` raw MCNK,
+  `5` yaw cases); renderer calibration PASS (`5` points, maximum error
+  `0.000015`); renderer manifest PASS (`7/7/7`); unified render baseline dry-run,
+  headless project load, runtime cache shutdown, coordination, documentation
+  and whitespace gates passed.
+- GUI regression: final ADT-boundary capture compared `2/2`, missing `0`,
+  failed `0` (cold mean `0.0002324`, changed ratio `0.0013741`; warm mean
+  `0.0000226`, changed ratio `0.0001285`). Earlier full capture produced all
+  `14` images; `11/14` met the strict changed-pixel threshold. The three
+  threshold-only differences retained low mean error (`<= 0.00622`) and were
+  visually classified as cold M2 readiness and liquid animation phase, with
+  unchanged camera, geometry alignment, area and streaming focus.
+- Fidelity: existing build-12340 calibrated points, raw ADT fixture and server
+  spawn fixture remain unchanged. Native parser workers retain exactly one
+  formula in `wow_chunk_reader.h`; the calibration verifier retains exactly one
+  independent formula so mapper and oracle cannot share a common-mode defect.
+- Rebuild: none. Local ignored extracted assets/native binary/cache junctions
+  were used for runtime checks and are not part of the commit.
+- Remaining risks: source scanning intentionally recognizes narrow high-signal
+  formula signatures rather than parsing arbitrary algebra; native formula
+  parity still relies on calibration/raw fixtures. Model-local M2/WMO basis
+  transforms and Godot-space LOD distance math are intentionally outside scope.
+- Recommended merge order: after `7c64e8d`; this package closes the remaining
+  M01 manual axis-conversion checklist item, but only the milestone integrator
+  may update target Evidence/status or set `OPENWC_TARGET_DONE`.
+- Documentation: coding review rule, coordinate-mapping module API/input-output/
+  data-flow/capability/risk/source-map sections, ADR 0001 and `RENDER.md` were
+  updated. Existing pure synchronous data-flow diagram remains authoritative;
+  no state/sequence diagram changed.
