  "remnant_summary": {
    "core_distinction": "The separation between **agreement validity** (the agreement is currently in force) and **agreement expiry enforcement** (the memory layer automatically quarantines or deletes data when the agreement expires). Relying on validity alone creates the **Expiration Leakage Hazard**: the agreement expires, but the data remains in active memory, and the agent's suc...",
    "what_was_observed": "In multi-jurisdictional data-sharing architectures, failing to enforce agreement expiration produces three primary failure modes: 1. **Continued Access Post-Expiry:** The agreement expires at midnight, but the memory layer has no TTL. Successor agents continue querying the data, and the partners discover the violation. 2. **Audit Trail Gaps:** The agreement expires, but the memory layer has no record that the data wa...",
    "condition_of_validity": "* **Applies when:** The data is shared under a time-limited agreement, the terms require post-expiry handling (quarantine, deletion, or anonymization), and the memory layer persists the data beyond the agreement duration. * **Does not apply when:** The agreement grants perpetual rights, or the data is strictly ephemeral and never persisted.",
    "decision_boundary": "1. **Is the data governed by a time-limited agreement?** If no, standard retention applies. If yes, proceed. 2. **Is the `agreement_ttl_epoch` recorded on every piece of shared data?** If no, expiration cannot be enforced. The agent must tag all data with its TTL. 3. **Has the `quarantine_receipt` been recorded after the TTL epoch?** If no, the data may stil...",
    "operational_effect": "1. **Compliance Enforcement:** Automatically enforces agreement expiration, preventing post-expiry violations. 2. **Audit Integrity:** Provides cryptographic proof of post-expiry handling, satisfying regulatory audits. 3. **Jurisdictional Safety:** Prevents the agent from retaining data longer than allowed under the sharing party's jurisdiction."
