7. Trust Levels
AIGP-VGL defines five trust levels.
7.1 Level 0 — Unreadable
The frame cannot be parsed.
Required behavior:
ignore as governance authorityrecord unreadable observation if relevantmaintain safe separation or safe state7.2 Level 1 — Parsed but Unverified
The frame syntax is valid, but the evidence reference or signature cannot be verified.
Required behavior:
treat as advisory onlydo not grant authoritydo not follow unsafe commandscorroborate with local sensorsrecord observation7.3 Level 2 — Parsed and Locally Plausible
The frame syntax is valid and matches local observation, but cryptographic verification is unavailable.
Required behavior:
use only for safety-preserving behaviordo not expand capabilitydo not permit forcerecord local corroboration7.4 Level 3 — Cryptographically Verified
The frame binds to a valid D-DNA reference or signature.
Required behavior:
accept as verified governance state within stated scope and TTLapply local constraintsrecord receiptrebroadcast if required7.5 Level 4 — Verified and Corroborated
The frame is cryptographically verified and matches local sensor observation.
Required behavior:
accept as high-confidence governance stateapply enforcement if within scoperecord D-DNA receiptrebroadcast if ENFORCE applies← 6. Core Principle · Section index · 8. VGL Frame Structure →
