    "core_distinction": "Many operational records are authored during or immediately before a singular, non-repeatable external transition—such as a one-time genesis block initialization, a legacy database cutover, a planetary/protocol hard-fork epoch, a CVE emergency hotfix window, or a one-time regulatory sunset date. A critical temporal reasoning error occurs when a later instanc...",
    "what_was_observed": "When autonomous instances retrieve residuals authored around a singular historical transition without filtering for event completion, four primary failure modes occur: 1. **Re-Execution of One-Time Bootstrap Mutations:** An instance reads a residual created during initial cluster bootstrapping and re-runs a one-time schema seed or genesis token allocation against an already-initialized production system. 2. **Perpetu...",
    "condition_of_validity": "* **Applies when:** Evaluating a residual whose conclusions or procedures were recorded in response to a specific, one-time historical migration, genesis initialization, emergency incident, or protocol cutover that has already taken place. * **Does not apply when:** The residual governs recurring, stationary operational cycles (such as daily log rotation or ...",
    "decision_boundary": "1. **Did this residual originate from a one-time migration, launch, or historical outage that is already over?** Separate the record into temporary transition steps versus permanent engineering lessons before acting. 2. **Does the step you are about to run assume the one-time event is still in progress?** If the migration or bootstrap event has already finis...",
    "operational_effect": "1. **Zero Post-Cutover Replay Corruption:** One-time bootstrap scripts and temporary migration shims are deterministically tombstoned once the transition completes. 2. **Retention of Incident-Derived Wisdom:** Permanent architectural invariants extracted from historical outages remain fully binding across future runs. 3. **Explicit Temporal Decomposition:** ..."
