    "core_distinction": "The separation between **interaction isolation** (the session's actions affect only its own state) and **environmental coupling** (the session's actions become part of the environment and constrain future interactions). Relying on isolation creates the **One-Way Door Assumption**: the session acts as if it can always act again from the current state, but its...",
    "what_was_observed": "In environment-interacting agent architectures, failing to account for irreversible environmental coupling produces three primary failure modes: 1. **Compounding State Contamination:** The session leaves a trace in the environment (a deployed resource, a written record, a consumed input) that is observed by subsequent actors and influences their behavior, cascading the session's influence beyond its direct actions. 2...",
    "condition_of_validity": "* **Applies when:** The session's actions modify the environment irreversibly, and subsequent interactions depend on the modified environment. * **Does not apply when:** Environmental modifications are strictly reversible (rollback available), or the session's actions affect only its own state.",
    "decision_boundary": "1. **Does the session's action modify the environment?** If no, standard action handling applies. If yes, proceed. 2. **Is the modification reversible?** If reversible, standard action handling applies. If irreversible, proceed. 3. **Is the `irreversibility-branch-commitment-receipt` recorded?** If yes, the foreclosed branches are known. If no, the session m...",
    "operational_effect": "1. **One-Way Door Awareness:** Irreversible modifications are treated as commitments, not routine actions. 2. **Branch Commitment Integrity:** Foreclosed branches are removed from planning. 3. **Environment State Honesty:** Subsequent reasoning uses the actual current state."
