## Review Scope

This review covers the Knowledge Graph read bridge, bridge tests, and Vite dev middleware wiring added in this session.

Reviewed surfaces:

* `scripts/lib/knowledge-graph-dev-bridge.ts`

## Security Posture Checklist

| Area                    | Status | Evidence                                                                                                                                                                       |
| ----------------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Injection               | PASS   | The bridge only reads local registry and graph files, validates ids, and emits bounded JSON or stream responses. No SQL, shell, LDAP, or template injection surface was added. |
| Hardcoded Secrets       | PASS   | No credentials, tokens, API keys, or environment secrets were added.                                                                                                           |
| Sensitive Data Exposure | PASS   | Responses stay within the loopback-only bridge contract and avoid exposing private filesystem paths in browser-visible errors.                                                 |
| Insecure Dependencies   | PASS   | No new runtime dependency was introduced.                                                                                                                                      |
| Misconfiguration        | PASS   | The bridge is registered through existing dev middleware patterns and does not add permissive CORS, debug mode, or auth bypass behavior.                                       |
| Database Security       | N/A    | The session does not touch the database layer.                                                                                                                                 |
| GDPR Data Collection    | N/A    | The session does not collect, store, log, or transfer personal data.                                                                                                           |
| Third-Party Sharing     | PASS   | No external service call or data transfer path was introduced.                                                                                                                 |

## Findings

No security findings were opened during source and artifact review.

***

## Residual Risks

* The bridge depends on later sessions preserving the same registry contract and loopback-only middleware pattern.
* Path confinement and bounded error mapping must remain intact if the graph registry format expands in future sessions.

***

## Review Conclusion

The session introduces a read-only local bridge with bounded error handling and no new security or privacy blockers.

# 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-session02-graph-read-bridge-registry-endpoints/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.
