## Security Posture Checklist

| Area                    | Status | Evidence                                                                                                                                       |
| ----------------------- | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| Injection               | PASS   | `git` and `graphify` are invoked through `execFileSync` with argv arrays only. Git URL input rejects whitespace and shell metacharacters.      |
| Hardcoded Secrets       | PASS   | No credentials, tokens, API keys, or long-lived secrets were added. Existing per-run token flow is reused.                                     |
| Sensitive Data Exposure | PASS   | Browser-visible status and error responses do not expose graphify candidate paths, token values, temp clone paths, or local source paths.      |
| Insecure Dependencies   | PASS   | No new runtime dependency was introduced.                                                                                                      |
| Misconfiguration        | PASS   | Mutating endpoints require loopback, `X-Claude-OS-Token`, non-production mode, and `HERMES_DASHBOARD_ADMIN=1`.                                 |
| Path Traversal          | PASS   | Graph ids are strict lowercase kebab-case, graph artifacts are confined to `src/data/graphs`, and removal deletes only stored graph artifacts. |
| Resource Cleanup        | PASS   | Temp Git clones and `graphify-out` scratch directories are cleaned up on success and failure.                                                  |
| Database Security       | N/A    | The session does not touch the database layer.                                                                                                 |
| GDPR Data Collection    | N/A    | The session does not collect, transfer, or log personal data. Local source paths are stored only in repo-local registry data.                  |
| Third-Party Sharing     | PASS   | The only external transfer path is operator-provided Git clone input behind the admin gate. No automatic third-party upload was added.         |

## Findings

No security findings were opened during source and artifact review.

***

## Residual Risks

* Admin-enabled ingest can execute local `git` and `graphify`; the bridge is intentionally dev-only and token-gated, and should not be exposed beyond loopback.
* Registry entries store absolute `graphPath` values for Shared Brain local consumers. Browser responses project those paths to relative graph paths, but future UI work must preserve that boundary.
* Operator-provided Git URLs may contact external hosts. The hook and later UI should keep this action explicit and admin-mediated.

***

## Review Conclusion

The session adds a write-capable local admin bridge with fail-closed boundary validation, argv-only process execution, path confinement, cleanup behavior, and browser-safe response projection. No security or privacy blockers remain for the validate workflow step.

# 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/phase26-session03-graph-ingest-removal-admin-bridge/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.
