K07 · evidence-bundled critical-infrastructure assurance
Multi-sensor physical evidence and disagreement
Direct answer
Require independent modalities, confidence and time quality, disagreement handling, safe delay measures, and authority-separated actuation.
Authority and evidence boundary. K07 publishes knowledge architecture, bounded reference records, procurement structures, local validation tools, signed synthetic fixtures, and point-in-time source review. It does not certify a facility, award a contract, authorize an operation, prove truth, establish deployment, or claim current operation.
Context
Any single radar, optical, thermal, acoustic, access-control or cyber sensor can fail, be spoofed, or be compromised.
Proposed reference decision
Require independent modalities, confidence and time quality, disagreement handling, safe delay measures, and authority-separated actuation.
Alternatives considered
- single-model classification
- camera-only response
- automatic destructive action from one sensor
Consequences
- sensor fusion and uncertainty are first-class evidence
- false-positive harm is bounded
- destructive effects remain separately authorized
Defeaters and reversal conditions
- common power or network failure
- unmeasured sensor latency
- one classifier controls actuation
- no safe uncertainty state

Use boundary
This record is a proposed reference decision. A competent owner must bind it to actual site constraints, authority, hazards, license conditions, interfaces, implementation evidence, and change control.
