A persistent, shared, queryable memory of physical space.
The SQLite-moment for physical-world memory — embeddable CRDT scene graph + universal sensor broker.
There is no persistent, shared ground-truth of a space that heterogeneous embodied agents can concurrently read and write. Research scene-graphs are centralized and never productized; cloud digital twins are latency-heavy and not embeddable; foundation world-models aren't a local, writable runtime memory.
Treat the physical environment as a first-class, local-first database: a spatiotemporal scene graph held at the edge, merged across agents via spatial-domain CRDTs, queryable in natural language, with delta subscriptions. Decouple the hard SLAM-alignment problem from the store — it consumes pose transforms an agent already computes.
Embeddable scene graph
A zero-server, link-it-like-SQLite spatiotemporal store of geometry, semantics, confidence, and last-seen.
Spatial CRDT merge
Concurrent multi-agent writes merge with confidence-weighting and temporal decay — not last-writer-wins.
Delta subscriptions
Agents subscribe to scene changes (“tell me when zone B changes”) instead of polling.
Sensor broker
A universal protocol broker turns incompatible physical sensor streams into semantic events.
