## 5. Database/Schema Alignment

### Status: N/A

No database, migration, persisted schema, or seed artifacts were changed in this session.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] LLM routes return deterministic useful fallback responses without provider credentials.
* [x] Provider-bound calls require `ANTHROPIC_API_KEY` plus `FACTIONOS_ALLOW_LLM_PROVIDER_TRANSFER=true`; otherwise they fall back locally.
* [x] LLM route validation rejects malformed bodies with `invalid_request` details and does not echo raw prompts, file contents, paths, tokens, or provider errors.
* [x] Codebase scan refuses filesystem root, non-approved roots, malformed limits/extensions, and default-ignored historical directories.
* [x] Scan and memory route responses avoid broad exposure of absolute roots, prompts, URLs, command previews, tokens, and transcript-like values.
* [x] Docs clearly distinguish local fallback, provider-transfer opt-in, local memory retention, and remaining erasure limitations.

### Testing Requirements

* [x] Server LLM tests cover plan, analyze, scan, idle, and memory deterministic fallback paths.
* [x] Server LLM tests cover provider-key-present but transfer-not-enabled behavior without network calls.
* [x] Server LLM tests cover malformed route bodies, scan caps, approved roots, ignored `EXAMPLES` paths, and redacted output.
* [x] Codebase walker tests cover ignore lists, symlink avoidance, caps, and truncation.
* [x] Focused Vitest, server typecheck, Biome check, `git diff --check`, ASCII, and LF checks pass.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] Biome format/lint succeeds for touched files.
* [x] TypeScript typecheck succeeds for `apps/server`.

## 7. Conventions Compliance

### Status: PASS

Spot-check of touched server files and docs found no obvious issues with naming, package boundaries, error handling, testing, or docs-as-current-behavior conventions.

***

## 8. Security & GDPR Compliance

### Status: PASS

**Full report**: See `security-compliance.md` in this session directory.

#### Summary

| Area     | Status | Findings |
| -------- | ------ | -------- |
| Security | PASS   | 0 issues |
| GDPR     | PASS   | 0 issues |

### Critical Violations

None.

## 9. Behavioral Quality Spot-Check

### Status: PASS

**Checklist applied**: Yes **Files spot-checked**:

* `apps/server/src/routes/llm.ts`

| Trust boundaries   | PASS   | `apps/server/src/routes/llm.ts`            | Route bodies and scan roots are validated before engine/walker use.            |
| Resource cleanup   | PASS   | `apps/server/tests/codebaseWalker.test.ts` | Symlink temp directory test cleans up external temp root.                      |
| Mutation safety    | PASS   | `apps/server/src/routes/llm.ts`            | No state-mutating duplicate action path added.                                 |
| Failure paths      | PASS   | `apps/server/src/lib/llmClient.ts`         | Provider blocked/missing/failure/timeout paths fall back deterministically.    |
| Contract alignment | PASS   | `apps/server/tests/llm.test.ts`            | Tests assert headers, response shapes, validation envelopes, and scan aliases. |

### Violations Found

None.

### Fixes Applied During Validation

None.

## Validation Result

### PASS

Session 06 is complete and validated.

## Next Steps

Run updateprd to mark the session complete. Phase 01 still has Session 07 unfinished, so the next workflow step after updateprd is plansession for Session 07.

# 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/phase01-session06-llm-fallback-and-scan-privacy/validation.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.
