# Phase 41 Plan 06: Verification Summary

**Full test suite run (30 server + 13 UI component tests passing), server tsc clean, UI tsc clean for Phase 41 files; ThemeContext backward-compat exports restored to fix regression from 41-05 worktree commit**

## Performance

- **Duration:** ~12 min
- **Started:** 2026-04-04T21:12:45Z
- **Completed:** 2026-04-04T21:25:00Z
- **Tasks:** 2 (1 auto + 1 checkpoint human-verify auto-approved)
- **Files created/modified:** 2

## Accomplishments

- Ran full server test suite: 30 Phase 41 tests pass (18 diagram-renderer + 12 icon-renderer)
- Ran all 60 UI test files: all pass; DiagramSourcePanel (6 tests) + ThemePreviewPanel (7 tests) verified
- Server `pnpm tsc --noEmit` exits 0 (clean)
- UI `pnpm tsc --noEmit` exits 0 for all Phase 41 files after THEME_META fix
- Fixed Phase 41-05 regression: ThemeContext was missing THEME_META and ORDERED_THEMES exports
- Identified and documented pre-existing failures (19 test failures in 4 files, 6 UI type errors) as out-of-scope
- Task 2 checkpoint auto-approved in autonomous mode: all Phase 41 components exist and are wired correctly

## Task Commits

1. **Task 1: Fix ThemeContext THEME_META/ORDERED_THEMES regression + test infra deps** - `56a36bbb` (fix)
2. **Task 2: Auto-approved checkpoint (no code changes)** - (no commit, verification only)

## Files Modified

- `ui/src/context/ThemeContext.tsx` — Added THEME_META and ORDERED_THEMES exports for backward compat with Layout.tsx, MarkdownBody.tsx, InstanceGeneralSettings.tsx
- `ui/src/pages/InstanceGeneralSettings.tsx` — Added ORDERED_THEMES to import statement
- `ui/package.json` — Testing devDeps (@testing-library/jest-dom, jsdom) from 41-05 worktree work committed here
- `pnpm-lock.yaml` — Updated for new testing devDeps

## Phase 41 Acceptance Criteria Status

| Criteria | Status |
|----------|--------|
| DIAG-01: Natural language → Mermaid SVG+PNG | IMPLEMENTED (diagram-renderer.ts, DiagramGeneratePanel.tsx) |
| DIAG-02: SVG+PNG download | IMPLEMENTED (DiagramPreview.tsx download buttons) |
| DIAG-03: Editable Mermaid source | IMPLEMENTED (DiagramSourcePanel.tsx, 6 tests) |
| DIAG-04: Diagram type selector | IMPLEMENTED (DiagramGeneratePanel.tsx type selector) |
| DIAG-05: Security — strip unsafe directives, DOMPurify | IMPLEMENTED (stripUnsafeDirectives, DOMPurify in diagram-renderer.ts) |
| ICON-01: LLM SVG icon generation | IMPLEMENTED (icon-renderer.ts, renderIconSet) |
| ICON-02: SVGO cleanup | IMPLEMENTED (validateAndCleanSvg with preset-default) |
| ICON-03: PNG rasterization (16/32/64) | IMPLEMENTED (sharp rasterization in icon-renderer.ts) |
| THEME-01: OKLCH palette from seed hex | IMPLEMENTED (buildPalette in theme-renderer.ts) |
| THEME-02: 7-role dark+light palette | IMPLEMENTED (background/surface/overlay/text/accent-1/2/3) |
| THEME-03: WCAG AA validation | IMPLEMENTED (wcagContrast.hex >= 4.5, badges in ThemePaletteGrid.tsx) |
| THEME-04: Scoped preview (not nav/sidebar) | IMPLEMENTED + TESTED (ThemePreviewPanel uses container ref, 7 tests) |
| THEME-05: CSS/Tailwind/VS Code/JSON export | IMPLEMENTED (ThemeExportTabs.tsx, exportToCss/exportToTailwind/exportToVSCode/exportToJson) |
| THEME-06: Apply to Nexus with confirm dialog | IMPLEMENTED (ThemeApplyConfirmDialog.tsx, applyCustomTheme in ThemeContext) |
| THEME-07: Persist custom theme | IMPLEMENTED (nexus-settings customTheme field, ThemeContext on-mount restore) |

## Decisions Made

- THEME_META and ORDERED_THEMES re-added as compatibility exports for `light | dark | custom` themes. Previous ThemeContext (feat(07-01)) had `catppuccin-mocha | tokyo-night | catppuccin-latte` with THEME_META; Phase 41-05 replaced with simplified light/dark/custom but dropped these exports, breaking 3 components.
- Pre-existing failures documented and deferred — not introduced by Phase 41.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Restored THEME_META and ORDERED_THEMES exports to ThemeContext**
- **Found during:** Task 1 (UI type check)
- **Issue:** Phase 41-05 worktree commit (`80c74e1c`) replaced ThemeContext.tsx entirely with a new light/dark/custom implementation that dropped the `THEME_META` and `ORDERED_THEMES` exports. This caused TypeScript errors in Layout.tsx (line 81 `THEME_META[theme].dark`), MarkdownBody.tsx (line 100 and 143 same), and InstanceGeneralSettings.tsx (lines 7, 84, 85).
- **Fix:** Added `THEME_META` record with display metadata for all three Theme values, added `ORDERED_THEMES` array, updated InstanceGeneralSettings.tsx import to include `ORDERED_THEMES`.
- **Files modified:** ui/src/context/ThemeContext.tsx, ui/src/pages/InstanceGeneralSettings.tsx
- **Commit:** 56a36bbb

### Out-of-Scope Pre-Existing Issues (Logged, Not Fixed)

The following failures existed before Phase 41 and are NOT caused by Phase 41 code:

**Server test failures (4 files, 19 tests):**
- `30-hardware-detection.test.ts` — nexusSettingsService default now returns `{ mode, voiceEnabled, voiceMode }` but test expects `{ mode }`. voiceEnabled/voiceMode fields were added in phases 30-01/36-02.
- `heartbeat-workspace-session.test.ts` — `deriveTaskKeyWithHeartbeatFallback` is not exported. Missing export from upstream.
- `agent-permissions-routes.test.ts` — Mine tab route returns 400 instead of 200. Route registered but handler incomplete (upstream PAP-878).
- `skill-registry-routes.test.ts` — Route implementation diverged from tests (agentSkillsDir vs agentId param name mismatch).

**UI TypeScript errors (6 errors in 5 files):**
- `AgentConfigForm.tsx` (detectModel), `useKeyboardShortcuts.ts` (onSearch), `useNexusMode.ts` (nexus queryKey), `usePiperTts.ts` (tts export), `useVadRecorder.ts` (redemptionFrames), `PersonalAssistant.tsx` (ToastTone values) — all from phases 06/21/33/34, not Phase 41.

**DB build failure:**
- `packages/db` — Duplicate migration `0046` (0046_smooth_sentinels.sql from upstream + 0046_tense_randall.sql from Phase 40). Pre-existing conflict from upstream merge.

---

**Total deviations:** 1 auto-fixed (Rule 1 - regression introduced by 41-05 worktree commit)
**Impact on plan:** All Phase 41 acceptance criteria met. THEME_META fix is backward-compatible and does not affect Phase 41's new functionality.

## Known Stubs

None — all Phase 41 content generators are fully implemented.
