      "description": "Know-Your-Agent (KYA) receipt for onboarding an autonomous agent counterparty: checks the agent's key is not revoked against a supplied BitstringStatusList credential (art-287), verifies its delegated-authority attestation chain (art-04), audits its key rotation posture (art-132), then GATES on a provable reputation score composed from prior OCG execution receipts (art-278). GATE: a composite reputation score below the tunable threshold theta ends the chain with no acceptance receipt issued; a score at or above theta continues to bind an NDA acceptance receipt referenced by hash (art-277). Theta is a composer policy_parameter, never a literal baked into kernel code, so it can be retuned without a rebuild. The receipt asserts unrevoked key, unexpired mandate, reputation at or above theta, and NDA accepted, each with its own evidence class; composite claim_strength honestly reports the weakest verification class among its steps. A Web Bot Auth signed-agent verification tail is an optional planned upgrade (rides the AGENTIC-NAV Section N2 landing, whose bypass-half is still unverified) and is omitted here, not missing. Verify-only; asserts only the four conditions it checked, never a broader safe-to-transact guarantee.",
