## Security Assessment

### Overall: PASS

| Category                      | Status | Severity | Details                                                                                                                                                           |
| ----------------------------- | ------ | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Injection (SQLi, CMDi, LDAPi) | PASS   | --       | No new shell or SQL construction paths were added. The new filter and engine code operate on parsed protocol objects and bounded text only.                       |
| Hardcoded Secrets             | PASS   | --       | No credentials, tokens, or secrets were added.                                                                                                                    |
| Sensitive Data Exposure       | PASS   | --       | The new prompt, lifecycle logs, and fallback logic avoid raw provider payloads, prompts, transcripts, or absolute paths. Existing server logging remains compact. |
| Insecure Dependencies         | PASS   | --       | No new runtime dependencies were introduced. Repository and server tests passed.                                                                                  |
| Misconfiguration              | PASS   | --       | No debug modes, permissive CORS changes, or insecure defaults were introduced by this session.                                                                    |

## GDPR Assessment

### Overall: N/A

This session does not introduce new user-facing personal data collection, storage, or sharing paths. The new code only processes bounded mission/session context already present in the server workflow and does not add a new personal-data surface.

***

## Notes

* `SuggestionManager.setAnalysisResult` now filters noisy analysis items before persistence.
* `normalizeStore` also filters persisted noisy analysis items during load so stale entries do not survive restart.
* Session summary generation uses the existing provider transfer guard in `llmClient` and falls back to deterministic local output when provider transfer is unavailable or disabled.
* Validation passed with server typecheck, focused session tests, and the full repository Vitest suite.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase18-session05-session-summary-engine-and-noise-filtering/security-compliance.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
