# Session Handoff — Design System v4 Migration

## What Was Done This Session

### 1. FlowPilot Message Bar + AI Script Builder (MERGED to main)
- PR #118 merged. Always-visible message bar in FlowPilot sessions, AI Script Builder at `/script-builder`, library reorg (My/Team Scripts tabs), FlowPilot-to-Script-Builder handoff, session abandon/close, unified session history.
- Eng review completed: normalized `script_builder_messages` table, typed content helpers, 6 edge case tests.

### 2. Design System v4 Migration (PR #119, open, branch: `refactor/design-system-v4`)
- Complete frontend redesign from glassmorphism to flat dark theme (Sentry/PostHog-inspired)
- **CSS Foundation:** New color tokens in `index.css`, all via CSS custom properties. Light mode ready (just needs `.light` class values).
- **Icon Rail Sidebar:** 72px rail with 5 grouped icons (Home, Work, Knowledge, Insights, Help). Full-height resizable drawer on hover. Pin-to-expand to 260px. Mobile hamburger overlay.
- **Component Sweep:** ~200 files migrated. All hardcoded hex replaced with semantic Tailwind tokens (bg-card, text-foreground, border-border, etc.).
- **Landing Page:** Flat surfaces, no glow, solid buttons.
- **Interactive Shadows:** Dark-mode-aware — elevated surfaces + faint cyan accent glow (black shadows invisible on dark bg).
- **Stat Cards:** 3px colored left borders.
- **Tab Toggles:** Active state uses `tab-active-shadow` (elevated bg + faint glow).

### 3. GTM Strategy (from /office-hours)
- Shadow & Ship approach: Michael uses ResolutionFlow on real tickets for 2 weeks, then hands logins to 5 MSP colleagues. Key metric: unprompted return.
- Design doc at `~/.gstack/projects/patherly-patherly/`

## What Needs To Be Done Next

### Immediate (Design System v4 polish)
1. **Home icon color fix:** The Home icon in the sidebar shouldn't have a cyan background when not active. Instead, the Home icon itself should always be cyan (brand accent), and only show the `bg-accent-dim` background when the route is actually `/`. Michael specifically requested this.
2. **Visual QA pass:** Michael hasn't done a full page-by-page walkthrough yet. Expect feedback on individual pages once he does.
3. **`font-label` cleanup:** ~10 files still reference `font-label` (deprecated alias for `font-mono`). Each needs inspection — some should be `font-mono`, others `font-sans text-xs`.
4. **Inline `style` attributes:** ~29 instances still use hardcoded hex in inline styles (sidebar, drawer, badges). Should be converted to CSS variable references or Tailwind classes where possible.

### Before Merging PR #119
- Run migrations: `docker exec resolutionflow_backend alembic upgrade head` (new tables from the Script Builder PR are on main now)
- Full visual QA with backend running
- Test mobile responsive (hamburger menu)
- Test FlowPilot session with new message bar + action bar positioning

### Future
- **Light mode toggle:** CSS variables are ready. Need to add `.light` class values in `index.css` + toggle in user settings/account page.
- **Script Builder testing:** The AI Script Builder hasn't been tested end-to-end with the backend running yet.

| `frontend/src/components/dashboard/StartSessionInput.tsx` | The Guided/Chat toggle |
| `frontend/src/components/dashboard/PerformanceCards.tsx` | Stat cards with colored borders |

## Key Lessons From This Session

- The component sweep agents missed `editor-ai/`, `guides/`, `maintenance/`, `scripts/`, `settings/` directories and `text-brand-dark` references. Always do a final grep audit after sweeps.
- `bg-[#hex]` hardcoding defeats the purpose of CSS variables. We had to do a second pass to replace 3,200+ hardcoded values with semantic tokens.
- Black shadows (`rgba(0,0,0,...)`) are invisible on dark backgrounds. Use elevated surfaces + faint accent glow instead.
- The sidebar flyout needed `position: fixed` to escape the CSS Grid cell clipping — `absolute` positioning was hidden behind the main content area.
- Flyout hover timing: individual item `onMouseLeave` was killing the flyout before the mouse reached the drawer. Only the outer wrapper should handle `onMouseLeave`.
