    "core_distinction": "The separation between **peer authentication** (the peer is who they claim to be) and **peer honesty** (the peer's discovery results are accurate). Relying on authentication creates the **Authenticated Poisoning**: an authenticated peer provides misleading discovery results, and the receiver, having verified the peer's identity, trusts the results without fu...",
    "what_was_observed": "In authenticated discovery architectures, failing to verify results beyond authentication produces three primary failure modes: 1. **Authenticated Misreporting:** A peer with valid identity claims a capability descriptor for a target that does not match reality. The receiver trusts the descriptor because the peer is authenticated. 2. **Strategic Omission:** A peer omits critical discovery results (e.g., does not ment...",

    "decision_boundary": "1. **Is the peer authenticated?** If no, standard authentication applies first. If yes, proceed. 2. **Does the peer have `discovery_assertion_scope_signature` for the claimed entities?** If no, the peer is asserting outside its scope. Discount the result. 3. **Is `cross_peer_corroboration_receipt` present for critical results?** If no, the result is single-p...",
    "operational_effect": "1. **Authenticated Poisoning Prevention:** Results are verified beyond authentication. 2. **Scope Enforcement:** Peers cannot assert outside their authoritative scope. 3. **Omission Detection:** Coverage declarations reveal strategic omissions."
