Bridge contract
One logical Bridge per managed building, with bounded connectors.
An Edge Node may host several connectors, but every message retains tenant, Site, Bridge, point, sequence, and source timestamps.
Connectors
Protocol adapters such as BACnet, Modbus, OPC UA, MQTT, or vendor REST normalize into one versioned contract.
Resilience
Local bounded queueing, batching, compression, idempotent retry, and health reporting.
Isolation
No PostgreSQL credentials and no required inbound exposure of the property network.
Preview gates
The connector is not the product until operations are proven.
Private preview requires certificate rotation, upgrade/rollback, queue limits, clock handling, connector diagnostics, incident procedures, and telemetry retention to operate together.
Bridge partnerships start from a concrete property protocol.
Connector work is qualified against an actual building, point inventory, network boundary, ownership model, and support agreement.
