Add private `SetCurrAndReturn(uint)` helper in PhysicsEngine that looks up the resolved id in `DataCache.CellGraph` and writes `CurrCell` when the cell is present. Wrap the four RESOLVED-id return sites in ResolveCellId: - indoor no-CellBSP return (trust FindCellList) - indoor sphere-overlaps-CellBSP return - outdoor→indoor building-transit return (foreach candidate) - outdoor terrain-grid return The final no-match `return fallbackCellId;` is intentionally NOT wrapped — stale beats null (the caller's seed is preserved unchanged). CurrCell has zero readers in src/ (verified by ripgrep); this is additive write-only, identical observable behavior to W1. One new unit test (CellGraphMembershipTests) proves RED→GREEN.
