"""AD-607: Memory Security Framework — extraction & poisoning defense tests.

Tests cover ten OSS sub-AD letters across three defense layers:
  - Retrieval (607a/b/c): validate_recall_result, validate_provenance,
    score_anchor_mismatch.
  - Response (607d): check_memory_leakage + cognitive_agent post-decision.
  - Privacy (607e/f/g/h/i): MemoryAccessPolicy on Oracle,
    federation inbound sanitization, federation outbound privacy filter,
    store-time prompt-injection detection, DP aggregation.
  - Operator (607j): /security memory slash subcommand.

v1 is OBSERVATIONAL by default — every enforce_* flag default-False.
