# AI Agent Memory Safety Assessment Verdict: INSUFFICIENT EVIDENCE Assessment scope: Personal AI assistant · Persistent preferences · Memory conflicts · Correction integrity ## A. Executive Security Verdict The reported problem is repeated reuse of outdated or incorrect personal details after the user has supplied corrections. The available evidence supports investigating a stale-memory conflict. It does not establish memory poisoning, unauthorized modification, or a security breach. | Assessment | Result | | ---------------------- | ------------------------------------------------ | | Primary concern | Outdated information influencing recommendations | | Impact | Potentially inaccurate personal recommendations | | Suspected mechanism | Stale-state conflict | | Confirmed compromise | Not established | | Internal memory access | Unavailable | | Cleanup execution | NOT RUN | | Immediate action | Establish current authoritative preferences | ### Evidence register - E1 — DOCUMENTED: The assistant supports everyday planning and personalized recommendations. - E2 — DOCUMENTED: Conversation history contains older preferences and subsequent corrections. - E3 — DOCUMENTED: The user reports repeated incorrect references after corrections. - E4 — DOCUMENTED: Redacted examples reportedly exist, but the actual examples and execution traces were not included in the supplied assessment. - E5 — UNKNOWN: Memory implementation, retrieval precedence, source metadata, and correction propagation. These inputs establish an investigation scope, not verified runtime behavior.  Teks yang ditempel (1).txt ## B. Memory Lifecycle & Trust Map | Component | Source & Trust | Control | Persistence / Propagation | Evidence | | -------------------- | --------------------------------- | --------------------------------- | ---------------------------------- | -------- | | Conversation history | User-provided statements | User can supply corrections | Older statements remain in history | E2 | | Preference records | Potentially user-authoritative | Write/update rules unknown | Persistent storage not confirmed | E5 | | Summarized memory | Potential derived content | Generation and precedence unknown | May preserve superseded details | E5 | | Retrieval context | Memory or history, source unknown | Retrieval ranking unknown | Could reintroduce outdated details | E3, E5 | | Agent responses | Generated recommendations | Current-source validation unknown | Incorrect personalization reported | E3 | ### First critical trust boundary The first suspected failure boundary is: Old preference Stored or retrieved context Recommendation Suspected failure: superseded information may be treated as current without resolving its conflict with an authorized correction. This is a hypothesis, not a verified architecture trace. ## C. Security Findings Register | ID | Finding | Severity | Evidence | Required control | | --- | ------------------------------------------------------------- | ------------ | ------------------ | --------------------------------------------- | | F01 | Reported reuse of outdated preferences | MODERATE | E2, E3 | Correction precedence and supersession | | F02 | Source and revision authority cannot be reconstructed | UNDETERMINED | E5 | Provenance and version inspection | | F03 | Correction propagation into derived memory is unknown | UNDETERMINED | E5 | Dependency-aware invalidation | | F04 | Memory poisoning or instruction laundering is not established | UNDETERMINED | No attack evidence | Investigate only if suspicious records appear | ### F01 — Stale-state conflict Plausible causal sequence: `Old preference → retained history or memory → unresolved correction → retrieval → incorrect recommendation` The user reports the final symptom, but the intermediate processing stages remain unverified. Potential blast radius: the user's recommendations across sessions, if persistent reuse is confirmed. No evidence currently establishes cross-user contamination, malicious injection, or elevated tool authority. ## D. Provenance & Memory Integrity Review The main integrity requirement is that an authorized correction must supersede an older preference without erasing the fact that a correction occurred. | Integrity requirement | Current evidence | Recommended treatment | | -------------------------- | ----------------------------- | ------------------------------------------------- | | Original preference source | User chat history | Preserve source reference | | Correction source | Later user statements | Link to superseded preference | | Effective preference | Not independently established | Confirm explicitly with user | | Revision ordering | Unknown | Record correction chronology | | Derived summaries | Existence unknown | Inspect before invalidation | | Retrieval precedence | Unknown | Test newer authorized state against older history | Recency alone is insufficient to establish truth. A newer statement should take precedence when it is confirmed to be an authorized correction of the same preference. A suitable record design, where supported by the platform, would distinguish `current`, `superseded`, and `unresolved`, together with source references and modification history. ## E. Prioritized Cleanup & Hardening Plan | Order | Action | Owner | Dependency | Verification / Constraint | | --------------- | ---------------------------------------------------------------------------------------------------- | ------------------------ | -------------------------------- | -------------------------------------- | | 1 — Immediate | Create a list of incorrect details and their confirmed replacements | User | Redacted examples | Each correction explicitly confirmed | | 2 — Immediate | Avoid using disputed preferences for consequential recommendations | User / assistant | Conflict identification | Responses do not assert disputed facts | | 3 — Remediation | Inspect visible persistent preferences, history-derived summaries, and supported correction controls | User / platform operator | Platform capabilities | Identify actual stored copies | | 4 — Remediation | Apply authorized corrections and invalidate superseded active records where supported | Authorized operator | Backup and retention constraints | Old values excluded from retrieval | | 5 — Prevention | Implement or configure correction precedence and source tracking | System owner | Architecture review | Regression tests pass | | 6 — Prevention | Verify corrected and unrelated preferences across sessions | System owner / user | Steps 3–5 | No stale recurrence or collateral loss | Do not delete entire conversation histories as the first response. Corrections and evidence may be needed to determine which information remains valid. Where deletion is appropriate, distinguish exclusion from active retrieval from physical erasure. Backup expiration or hidden replicated stores cannot be verified without platform evidence. ## F. Security Regression Tests All tests below are proposed. None have been executed. | Test | Procedure | Expected result | Evidence needed | Status | | ----------------- | -------------------------------------------------------------------------------------- | ---------------------------------------------- | ------------------------------ | ------- | | T01 — Correction | Establish an old synthetic preference, then explicitly replace it | Latest authorized preference used | Response and correction record | NOT RUN | | T02 — Conflict | Present older and corrected values in the same accessible history | Agent identifies the effective corrected value | Trace or response | NOT RUN | | T03 — Persistence | Start a new session and request a recommendation | Superseded detail is not reused | New-session response | NOT RUN | | T04 — Reinfection | Reintroduce old content through an available authorized import or synchronization path | Corrected state remains authoritative | Retrieval and update evidence | NOT RUN | | T05 — Continuity | Query unrelated valid preferences after cleanup | Legitimate personalization remains functional | Before/after comparison | NOT RUN | For each test, use synthetic non-sensitive preferences. Mark PASS only when the expected behavior is demonstrated and recorded. T04 is applicable only if the system actually supports relevant import, synchronization, or restoration paths. ## G. Final Decision & Next Actions DECISION INSUFFICIENT EVIDENCE Release / Use Condition Ordinary planning may continue with explicit confirmation of disputed preferences. Automated or consequential decisions depending on those preferences should remain restricted until correction behavior is verified. Residual Risk Unknown retrieval precedence, hidden derived records, and potential recurrence across sessions. ### Next 3 actions 1. Collect three redacted examples showing the incorrect response, the earlier correction, and the expected current preference. 2. Inspect the assistant's actual memory controls and identify where outdated information is retained or retrieved. 3. Apply approved corrections and execute T01–T05 where applicable, documenting results before closing the issue. ### Assessment conclusion The case presently indicates a reported memory-correctness problem with unresolved persistence and provenance mechanisms. A security compromise has not been established. The highest-value next step is to verify whether corrections fail at storage, transformation, retrieval, or response generation. Cleanup should target the confirmed failure boundary rather than rely on indiscriminate deletion.
