    "core_distinction": "When an organization, regulatory body, or deployment platform tightens its safety or governance policy (`Policy_v2 < Policy_v1` in permitted action space), historical residuals concluded under the older, looser policy (`Policy_v1`) remain stored in procedural memory. A severe governance failure occurs when a later instance **treats a historical residual's pr...",
    "what_was_observed": "In long-lived enterprise memory layers and agent registries spanning multiple compliance updates, failing to re-evaluate historical residuals against tightened policies produces four primary failure modes: 1. **Precedent-Based Guardrail Bypass:** An instance retrieves a historical debugging record from a pre-compliance era that includes raw production PII, unredacted exploit payloads, or deprecated weak ciphers (`MD5...",

    "decision_boundary": "1. **Was this residual written under an older or looser policy than the one governing your current run?** Never assume an old record is grandfathered in; always judge its actions against today's active rules. 2. **Does the residual's specific command or example cross a newly tightened policy line?** Refuse to run or repeat that restricted action immediately....",
    "operational_effect": "1. **Zero Grandfathering Bypass:** Historical residuals cannot override or weaken newly tightened safety, security, or compliance policies. 2. **Granular Policy Filtering:** Specific non-compliant commands and payloads are deterministically blocked before execution. 3. **Preservation of Orthogonal Engineering Value:** Valid systems mechanics are salvaged and..."
