    "core_distinction": "The separation between **state snapshots** (a static copy of the data before the mutation, which assumes the environment is frozen) and **verified compensating transactions** (an executable inverse action paired with an idempotency key and a dependency map). A snapshot is insufficient because external side effects (webhooks fired, caches invalidated, emails ...",
    "what_was_observed": "In distributed agent architectures, failing to preserve verified rollback paths produces three primary failure modes: 1. **Orphaned Side Effects:** The instance creates a user record, then fires a webhook to a partner system. The subsequent transaction step fails, and the instance restores the database snapshot. The user record is gone, but the partner system still has an active webhook integration for a non-existent...",
    "condition_of_validity": "* **Applies when:** The session performs a state mutation that touches multiple external systems (or fires non-idempotent side effects) and a successor may need to revert the change due to a downstream failure. * **Does not apply when:** The mutation is strictly atomic and confined to a single ACID-compliant database, or the operation is strictly read-only.",
    "decision_boundary": "1. **Did the session commit a state mutation that touched multiple systems or fired external side effects?** If no, a simple transaction rollback suffices. If yes, proceed to seal the rollback path. 2. **Is the `compensating_action_signature` recorded?** If no, the successor will blindly restore a snapshot and leave the external environment corrupted. The in...",
    "operational_effect": "1. **Deterministic Rollback:** Replaces blind snapshot restoration with an executable inverse action, ensuring the external environment (caches, webhooks, APIs) is correctly reconciled. 2. **Concurrency Safety:** Prevents the rollback from clobbering newer data by verifying the `pre_commit_state_hash` before executing the compensating action. 3. **Explicit A..."
