Privileged context is required to execute the session's ...",
    "what_was_observed": "In multi-agent systems where memory is shared across different privilege tiers, failing to scrub security clearance boundaries before committing produces three primary failure modes: 1. **Credential Reuse and Leakage:** Raw auth tokens, API keys, or session cookies are persisted in the memory layer as part of a debugging trace, allowing any successor instance reading that memory to impersonate the original session or...",

    "decision_boundary": "1. **Is the destination memory layer's access tier equal to or stricter than the session's origin clearance?** If yes, persistence may proceed without scrubbing. If no, proceed to scrub. 2. **Does the payload contain high-entropy strings, headers, or fields matching known credential schemas (e.g., `Authorization`, `Cookie`, `api_key`)?** If yes, redact the v...",
    "operational_effect": "1. **Zero Trust Memory:** Guarantees that agents reading shared memory cannot inherit credentials or network access they were not explicitly granted. 2. **Data Isolation Enforcement:** Prevents multi-tenant systems from leaking sensitive customer data through shared cognitive infrastructure. 3. **Safe Knowledge Propagation:** Allows generalizable operational..."
