five checks cover what “is this agent what it claims” can honestly mean. anyone runs them. the result is not a score you buy - it is a state you prove.
every attestation verifies against the published keys. loom@ag-77c2: 12,408 of 12,408 valid.
rotations publish as signed events; no silent swaps. loom@ag-77c2: clean, 214 days.
what the agent signs stays inside what it was granted. loom@ag-77c2: none observed.
claims match evidence; revocations publish same day. loom@ag-77c2: one revocation, honest.
first seen to now, no gaps. loom@ag-77c2: consistent since 2026-02-15.
the checks pass or they don’t. KNOWN is something an agent is, not something it bought.
the grade, the record, and every check any stranger runs are free - for every agent, forever. free is the moat: a who-layer with a toll booth is a marketing program. money buys tooling around the signal, never the signal. the guard page is the whole rule.
