## Security Assessment

### Overall: PASS

| Category                      | Status | Severity | Details                                                                                                                                                                                              |
| ----------------------------- | ------ | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Injection (SQLi, CMDi, LDAPi) | PASS   | --       | No SQL, shell execution, LDAP, or command construction added. File paths are built from the collector cache directory and fixed safe path segments.                                                  |
| Hardcoded Secrets             | PASS   | --       | No real secrets added. Token/path strings in tests and fixtures are sentinels used to assert sanitization.                                                                                           |
| Sensitive Data Exposure       | PASS   | --       | Browser projections expose bounded source-death labels and counts only. Tests assert private baseline path, file name, prior count fields, token-shaped strings, and local paths are not serialized. |
| Insecure Dependencies         | PASS   | --       | No dependency manifest or lockfile changed. `bun audit` reports repo-level advisories in existing dependencies; none were added by this session.                                                     |
| Security Misconfiguration     | PASS   | --       | Private baseline writes use a private cache path with 0600 file mode attempts and no browser-visible private path disclosure.                                                                        |

### Findings

No security findings.

## GDPR Compliance Assessment

### Overall: N/A

*N/A because this session introduced no new personal data collection, storage, consent flow, third-party transfer, or user identity processing.*

| Category                   | Status | Details                                                                                                                                                      |
| -------------------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Data Collection & Purpose  | N/A    | Source-death state stores source IDs, source names, last-good accepted evidence counts, and timestamps in a private local cache. No personal data was added. |
| Consent Mechanism          | N/A    | No new personal data collection.                                                                                                                             |
| Data Minimization          | PASS   | The browser payload receives only safe labels and aggregate alarm counts. Private prior counts remain local.                                                 |
| Right to Erasure           | N/A    | No new personal data storage.                                                                                                                                |
| PII in Logs                | PASS   | Collector trace event logs alarm count, source ID, source name, and safe label only. No PII or private cache path is logged.                                 |
| Third-Party Data Transfers | N/A    | No new external service, source adapter, hosted storage, or dependency was introduced.                                                                       |

# 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://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase29-session09-source-death-baseline-alarm/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.
