Qualified location and map match

Carry observed position, dead-reckoning state, map-match alternatives, confidence and expiry into navigation, telemetry and safety consumers.

Authority model

Name the source—and name what it cannot prove.

The same message can be observation, projection, plan, receipt or physical evidence. This contract keeps those meanings separate.

Authority

Observed position remains separate from calculated match; the location runtime owns qualification and expiry.

Degraded behavior

Ambiguity, tunnel, sequence gap and expired dead reckoning hold dependent progression instead of inventing a lane or road.

Outcome boundary

A qualified reference position is not proof of physical arrival, lane-level localization or safety-function availability.

Product allocation

A product can appear on both sides when it transforms one authority into another; each transformation retains its own evidence.

Transport allocation

The program can select one or more transports without changing the source authority or failure contract.
