    Type Declaration

    • ReadonlyANNOTATIONS: "annotations"

      Collaboration annotation pins (markup), keyed by annotation id. Synced by Yjs alongside the model but intentionally NOT part of the IFCX snapshot/seed (snapshotToIfcx only walks ENTITIES) — markup is room overlay data, not BIM.

    • ReadonlyENTITIES: "entities"
    • ReadonlyGEOMETRY: "geometry"
    • ReadonlyMETA: "meta"
    • ReadonlyMODELS: "models"

      Model slots (#4444): slotId → ModelSlotRecord, one per model the owner shared into the room. Entity paths are qualified by slot (/<slotId>/<GlobalId>, see model-slot.ts), so two copies of one file — same bytes, same GlobalIds — are two slots and never one merged entity set. A room seeded before slots existed has an empty map; readers treat that as a single implicit slot over the unqualified /<GlobalId> paths.

    • ReadonlyOVERLAY_TOMBSTONES: "overlay.tombstones.registry"

      Per-path overlay-tombstone registry (path → boolean), owned by snapshot/overlay-tombstones.ts. Root-level, not nested under META, so concurrent peers merge into one map instead of racing (#5219).

    • ReadonlyRELATIONSHIPS: "relationships"
