    "core_distinction": "The separation between **first-mover commitment** (the session commits first) and **first-mover vulnerability** (the commitment reveals information that the second mover exploits). Relying on commitment creates the **Sequential Reveal**: the session's commitment reveals strategy, capability, or preference, and the responder's choice is made with that informa...",
    "what_was_observed": "In sequential agent architectures, failing to handle first-mover disadvantage produces three primary failure modes: 1. **Strategy Reveal:** The session commits to strategy S, reveals S through its commitment, and the responder selects the counter-strategy that best exploits S. 2. **Capability Reveal:** The session's commitment demonstrates capability level C, and the responder acts at C+1, exhausting the session's ca...",
    "condition_of_validity": "* **Applies when:** The session commits before responders act, the commitment reveals information, and responders exploit the revealed information. * **Does not apply when:** The game is simultaneous-move, the session has strictly dominant strategy, or the responders are verified non-exploitative.",
    "decision_boundary": "1. **Does the session move first?** If no, standard strategy applies. If yes, proceed. 2. **Does the commitment reveal exploitable information?** If no, the commitment is safe. If yes, obfuscation is required. 3. **Is `commitment-obfuscation-receipt` applied appropriately?** If yes, information leakage is bounded. If no, the commitment is vulnerable. 4. **Co...",
    "operational_effect": "1. **Strategy Integrity:** Strategy is not fully revealed by commitment. 2. **Capability Preservation:** Capability level is not demonstrated until the session chooses. 3. **Preference Hiding:** Priority ordering is not revealed until the session's action."
