Interface: BaseOccupancyGrid
Defined in: packages/wayfinding/src/grid-types.ts:103
An OccupancyGrid with walls, opening gaps, and fixture/kiosk obstacles already rasterized (buildBaseOccupancyGrid) — everything that is not relaxation-rung- specific — plus the cell-space geometry restampOccupancyGrid needs to apply the rung-specific dynamic layers (wall-vertex clearance discs, blocked-unit fills) without re-deriving ring geometry from lng/lat or re-rasterizing walls (issue #483: "cache the per-level base occupancy grid ... so the relaxation ladder restamps only the dynamic layers per request instead of re-rasterizing walls on every ladder rung and every route call"). See getBaseOccupancyGridForLevel in grid-relaxation.ts for the per-archive/per-level cache built on top of this.

data:
Uint8Array
Defined in: packages/wayfinding/src/grid-types.ts:83
Row-major occupancy: data[y * width + x]. 1 = blocked (wall stroke, or space outside every unit polygon), 0 = walkable.

derated:
boolean
Defined in: packages/wayfinding/src/grid-types.ts:89
True when memoryBudgetCells forced a lower resolution than requested.

doorGapEndpointsCells:
MetrePoint[]
Defined in: packages/wayfinding/src/grid-types.ts:109
Every Opening's door-gap endpoints (jamb classification for wall-vertex clearance discs), in cell-index space.

originMetres:
MetrePoint
Defined in: packages/wayfinding/src/grid-types.ts:87
Metre-space coordinate of grid cell (0,0)'s lower corner (the padded floor bbox min).

projector
projector:
GridProjector
Defined in: packages/wayfinding/src/grid-types.ts:85
Equirectangular projector (origin = floor bbox centroid) used to build this grid.

unitIds
unitIds:
string[]
Defined in: packages/wayfinding/src/grid-types.ts:105
Unit ids aligned 1:1 with unitRingsCells (units with no usable polygon geometry are omitted, same as buildOccupancyGrid's own filtering).
unitRingsCells
unitRingsCells:
MetrePoint[][]
Defined in: packages/wayfinding/src/grid-types.ts:107
Each unit's boundary ring, already projected and converted to this grid's cell-index space.
