Report #101395

[frontier] Poisoned memory or retrieved context changes agent behavior across sessions

Cryptographically sign or version memory writes; run integrity checks on retrieved context before use; separate durable memory from working memory; detect anomalies in recall results that contradict the codebase or prior verified facts.

Journey Context:
OWASP ASI06 \(Memory & Context Poisoning\) recognizes that agents increasingly persist state in vector stores, memory APIs, and RAG systems. A single poisoned memory can reshape behavior long after the injection. The 2026 pattern is to treat memory like a database: writes are validated, reads are logged, and retrieved 'facts' must be reconciled against a source of truth before they influence planning. This is why black-box memory layers like Nautilus Compass keep raw prompts so drift can be scored, not just recalled.
