## 6. Database/Schema Alignment

### Status: N/A

**Evidence**: `rg -n "(migrate|migration|schema|database|sql|prisma|drizzle|indexedDB|localStorage|persist\\(|DEFAULT_TRANSIENT_SETTINGS|expandedBottomRailSurfaceId|setExpandedBottomRailSurfaceId)" ... || true` found no DB-layer or schema artifacts in touched session files. It confirmed `expandedBottomRailSurfaceId` is in the existing transient store state and its setter does not persist.

**Issues found**: None

## 7. Success Criteria

From spec.md:

**Functional requirements**:

* PASS - Quest Board, Orchestration, and War Room expose stable shell-level expand controls, verified by `CockpitShell.test.tsx` and focused tests.
* PASS - Panel-background clicks open only outside guarded descendants, verified by `BottomRailExpansionHost.test.tsx`.
* PASS - Expanding one surface replaces the previous one, verified by host and app shell tests.
* PASS - Backdrop, close button, and Escape close the surface and focus restore is covered by tests.
* PASS - Expanded surfaces use dialog ARIA and compact surfaces stay normal regions, verified by source inspection and tests.
* PASS - One mounted panel implementation per bottom surface is verified by `expectSingleBottomPanelTrees()`.

**Testing requirements**:

* PASS - Component tests cover open, close, backdrop, Escape, focus restore, one-at-a-time state, guarded controls, and same-instance child preservation.
* PASS - App shell tests cover all three bottom-rail surfaces, stable ids, replacement, shell notes, and no duplicate panel rendering.
* PASS - Focused web tests and web typecheck completed.

**Quality gates**:

* PASS - ASCII and LF checks passed.
* PASS - Biome lint and format checks passed.
* PASS - Code follows conventions by package-scope spot-check.
* PASS - Product-surface inspection found no diagnostics in normal UI.

## 8. Conventions Compliance

### Status: PASS

**Categories spot-checked**: naming, file structure, error handling, comments, testing, and database conventions when relevant.

**Convention violations**: None. The session stayed inside `apps/web`, used TypeScript component and test patterns, kept Biome formatting/linting clean, and did not introduce database conventions.

## 9. Security & GDPR Compliance

### Status: PASS

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

#### Summary

| Area     | Status | Findings |
| -------- | ------ | -------- |
| Security | PASS   | 0 issues |
| GDPR     | N/A    | 0 issues |

**Critical violations**: None

## 10. Behavioral Quality Spot-Check

### Status: PASS

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

* `apps/web/src/components/BottomRailExpansionHost.tsx`
* `apps/web/src/App.tsx`
* `apps/web/tests/BottomRailExpansionHost.test.tsx`
* `apps/web/tests/CockpitShell.test.tsx`

**Categories spot-checked**: trust boundaries, resource cleanup, mutation safety, failure paths, and contract alignment.

**Violations found**: None

**Fixes applied during validation**: None

## 11. UI Product-Surface Spot-Check

### Status: PASS

**Surfaces inspected**: Source inspection for bottom-rail host controls in `BottomRailExpansionHost.tsx` and App-level shell tests for Quest Board, Orchestration, and War Room focused surfaces.

**Diagnostics found in primary UI**: None

**Allowed debug/admin surfaces**: None introduced

**Fixes applied during validation**: None

## Validation Result

### PASS

The session satisfies the code-review gate, task completion, deliverables, encoding, tests, typechecks, conventions, security, GDPR, behavioral quality, and product-surface requirements. Node is v24.14.0 locally while project conventions target Node 26.2.0+, but all configured validation commands passed in the available environment.

### Unresolved Failures And Blockers

None

## Next Steps

Next command: `updateprd`

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/phase21-session02-shared-expansion-host/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.
