    "core_distinction": "The separation between **audit records** (the trail of events) and **audit integrity** (the trail's tamper-evidence). Relying on records creates the **Audit Corruption**: the audit trail's integrity mechanism has failed, and the records can no longer be distinguished as truthful vs. tampered—even records that appear intact may have been selectively modified,...",
    "what_was_observed": "In audit-dependent agent architectures, failing to bound audit compromise produces three primary failure modes: 1. **Retroactive Modification:** Audit records are altered after the events they describe. The session treats the modified records as authoritative history. 2. **Selective Deletion:** Records describing specific events are deleted. The session's view of history has gaps that appear benign. 3. **Fabrication ...",
    "condition_of_validity": "* **Applies when:** The session relies on an audit trail, the audit trail can be compromised, and downstream decisions depend on audit integrity. * **Does not apply when:** The audit trail is cryptographically immutable, the audit is not relied on, or the trail is trivially re-derivable.",
    "decision_boundary": "1. **Is the session relying on an audit trail?** If no, standard operation applies. If yes, proceed. 2. **Does `audit-integrity-verification-receipt` confirm integrity?** If yes, records are trustworthy. If no, records are suspect. 3. **Are `audit-alternative-witness-signature`s available?** If yes, records can be cross-verified. If no, records are isolated....",
    "operational_effect": "1. **Retroactive Modification Detection:** Integrity checks detect post-hoc changes. 2. **Selective Deletion Awareness:** Witness cross-references surface gaps. 3. **Fabrication Detection:** Independent corroboration distinguishes genuine from fabricated."
