    "core_distinction": "The separation between **origin claim** (the peer says \"this came from X\") and **origin attestation** (cryptographic proof that the reference actually originated from X). Relying on claims creates the **Origin Spoofing**: a peer relays a reference, claims it came from a highly-trusted origin, and the receiver trusts the reference beyond what its actual origi...",
    "what_was_observed": "In peer-to-peer reference propagation, failing to attest origin produces three primary failure modes: 1. **Trusted-Origin Framing:** An attacker relays a malicious reference, claiming it came from a highly-trusted origin (e.g., \"AWS officially recommends this tool\"). The receiver trusts it based on the claimed origin, unaware that AWS never endorsed it. 2. **Origin Laundering:** An untrusted origin's reference is rel...",
    "condition_of_validity": "* **Applies when:** References propagate with origin claims, origins are heterogeneous in trust, and receivers weight references by origin. * **Does not apply when:** References are strictly content-addressed (origin irrelevant), or all peers are fully trusted.",
    "decision_boundary": "1. **Does the reference include the origin's signature?** If yes, origin is attested. If no, origin is claimed, not attested. 2. **Is the `relayer_claim_attestation_signature` clearly labeled as a claim, not an attestation?** If yes, receivers can weight the claim. If no, the claim may be mistaken for attestation. 3. **Does the origin's `origin_repudiation_a...",
    "operational_effect": "1. **Origin Spoofing Prevention:** Origin signatures prevent false-origin claims. 2. **Claim/Attestation Clarity:** Relayers' claims are distinguished from origins' signatures. 3. **Repudiation Handling:** Repudiation announcements override relayers' claims."
