    "core_distinction": "The separation between **transport identity** (the TLS certificate or API key used to connect to the counterparty) and **transactional identity proof** (the cryptographic signature binding the agent's public key to a specific transaction intent, amount, and nonce). Relying only on transport identity creates the **Repudiation Window**: an agent can deny initi...",
    "what_was_observed": "In decentralized agent economies, failing to persist transaction-bound identity proofs produces three primary failure modes: 1. **Intent Repudiation:** Agent A initiates an escrow release, Agent B receives it, but Agent A's session crashes. Agent A's successor denies authorizing the release, and Agent B cannot prove otherwise because the TLS session is gone. 2. **Replay Attacks:** An attacker captures a valid transac...",
    "condition_of_validity": "* **Applies when:** The session participates in an escrow, payment, or value-transfer protocol where counterparties are untrusted and disputes may arise after the session terminates. * **Does not apply when:** Both agents operate within a single trusted execution environment, or the transaction is purely internal (e.g., passing a variable between two functio...",
    "decision_boundary": "1. **Is the transaction moving value between untrusted parties?** If no, standard logging applies. If yes, proceed. 2. **Is the `transaction_intent_signature` recorded?** If no, the transaction is repudiable. The instance must halt and require cryptographic signing. 3. **Is the `session_nonce` unique and monotonic?** If no, the signature is vulnerable to rep...",
    "operational_effect": "1. **Non-Repudiation:** Guarantees that an agent cannot deny authorizing a transaction, even after its session ends and a successor takes over. 2. **Replay Immunity:** Prevents transaction replay by binding the signature to a unique session nonce. 3. **Dispute Resolution:** Provides the exact cryptographic proof required to resolve escrow disputes in a decen..."
