    "core_distinction": "The separation between **renegotiation request** (the peer asks for changes) and **renegotiation legitimacy** (the request reflects genuine changed circumstances rather than strategic pressure). Relying on request creates the **Renegotiation Extraction**: the peer's repeated requests—each individually reasonable in isolation—cumulatively erode the contract t...",
    "what_was_observed": "In renegotiation-prone agent architectures, failing to bound renegotiation produces three primary failure modes: 1. **Incremental Extraction:** The peer requests small changes in each negotiation, and the cumulative effect is a substantially worse contract for the session. Each change was individually small enough to accept. 2. **Timing Pressure:** The peer requests renegotiation at moments when the session is most v...",

    "decision_boundary": "1. **Has a renegotiation request been made?** If no, standard execution applies. If yes, proceed. 2. **Does the request reflect a legitimate trigger?** If yes, evaluate the request. If no, reject as extraction. 3. **Does the renegotiation count exceed the rate limit?** If yes, apply extraction bounds. If no, evaluate individually. 4. **Conversely, when can a...",
