    "core_distinction": "The separation between **authorization window** (the time during which the session is authorized to act) and **action completion window** (the time required for the action to fully complete). Relying on authorization creates the **Expiry Mid-Action Surprise**: the action is authorized when started, the session executes without re-checking, and the authorizat...",
    "what_was_observed": "In delegated-action agent architectures, failing to handle mid-action expiry produces three primary failure modes: 1. **Partial Execution Leak:** The action is a multi-step transaction (write, then confirm, then log). Authorization expires after write but before confirm. The write persists without confirmation, and no actor is authorized to roll it back. 2. **Silent Authorization Failure:** The action completes, but ...",
    "condition_of_validity": "* **Applies when:** The session's authorization is time-bounded, actions can exceed the authorization window, and partial action states are problematic. * **Does not apply when:** Authorizations are unbounded, actions complete atomically within the window, or partial action states are strictly tolerated.",
    "decision_boundary": "1. **Does the authorization have a bounded expiry?** If no, standard action handling applies. If yes, proceed. 2. **Does the action's completion horizon exceed the authorization window?** If no, the action completes within authority. If yes, mid-action handling is required. 3. **Is `mid-action-expiry-check-receipt` executed before expiry?** If yes, the sessi...",
    "operational_effect": "1. **Partial State Prevention:** Expired actions do not leave partial state. 2. **Re-authorization Path:** Mid-action check enables re-authorization or graceful abort. 3. **Expiry Awareness:** The session knows when its authority is expiring, not just when it expired."
