Erik 865634f450 docs(spec): indoor BSP world-origin / world-rotation fix (Bug B) ... Single-call-site defect in TransitionTypes.cs:1442 — the indoor cell BSP query invokes BSPQuery.FindCollisions without passing the cell's world rotation or world origin. Path 3 step-down + Path 4 land write ContactPlanes with D ≈ 0 instead of the cell's world floor Z. 320 corrupt CP writes per Holtburg session per the [cp-write] probe capture 2026-05-20. Fix: decompose cellPhysics.WorldTransform once, pass rotation + translation. Mirrors the existing correct pattern at :1808 (object BSP via FindObjCollisions). This is slice 1 of 2 for the indoor ContactPlane retention phase. Slice 2 (Bug A — TryFindIndoorWalkablePlane removal) deferred pending Bug B retest.
