Device observations and immutable media identity remain authoritative; human review appends disposition without mutating trigger evidence.
Video trigger, media evidence and custody
Correlate trigger, clocks, media segments, policy, access, review, export and lifecycle without rewriting source evidence.
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.
Lens, thermal, storage, clock, upload and corruption states degrade independently; protected evidence survives configured pressure.
A trigger is not a judgment; metadata is not media; retrieval authorization is not byte delivery; export intent is not custody receipt.
Producer and consumer responsibilities are explicit.
A product can appear on both sides when it transforms one authority into another; each transformation retains its own evidence.

The program can select one or more transports without changing the source authority or failure contract.
Compatibility vector
- schema or ABI version
- producer release
- consumer release
- policy and entitlement revision
- content/configuration revision
- territory/platform profile
Acceptance evidence
- contract compatibility
- nominal and negative scenarios
- ordering, replay and idempotency
- latency, capacity and resource bounds
- security, privacy and role enforcement
- offline, recovery and rollback
- target or operational acceptance

Allocate owners, transport, schema, releases, policy, content, degradation, replay and target acceptance in one controlled baseline.
