# Responsive Planner — Iteration 1

## Analysis Summary

Audited all 10+ key files. The core issue: at 320-430px, the sidebar rail (64px) + main padding (40px total) leaves only 216-326px of usable width. The sidebar as a left rail makes no sense at these widths.

## Key findings

1. **Sidebar**: Fixed 64px rail on mobile (<1024px), 304px expanded overlay. At <600px this should become a bottom nav bar.
2. **Main padding**: `p-5` = 20px all sides. Eats 40px from an already narrow viewport.
3. **KPI grid**: Hardcoded 2-column grid, no responsive override. Cards get ~108px wide at 320px.
4. **Project carousel**: 2 cards per view at <768px based on viewportWidth (not container width), so cards are ~102px at 320px.
5. **Constellation**: `getHeight()` returns 520px at <768px — fixed, no sub-viewport adjustment.
6. **Card.tsx**: `overflow: hidden` + `padding: 24px` on Card wrapper.
7. **Detail panel**: 24px side padding, 100vw on mobile already — OK.
8. **Timeline badges**: `flexShrink: 0` + `whiteSpace: 'nowrap'` can cause overflow.
9. **No sub-480px breakpoint** in Tailwind — xs starts at 480px.
10. **ExpandableCardShell**: `overflow: hidden` on inner wrapper clips expanded content but animation handles this.

## Decision: Bottom nav approach
- At <600px: hide sidebar entirely, show a fixed bottom tab bar
- Bottom bar: 56px tall, has 3 nav icons + hamburger for full drawer
- Drawer: slides up as a sheet with full sidebar content
- Main content: remove margin-left, add padding-bottom for bottom bar
- Framer Motion for drawer animation (already available)

## Builder — Iteration 2

### All 8 phases implemented

**Phase 1 — Sidebar → Bottom Nav:**
- Created `MobileBottomNav.tsx` with collapsed tab bar (56px) + drawer (Framer Motion slide-up)
- `Sidebar.tsx` returns null at <600px via `isMobileNav` state
- `DashboardLayout.tsx` conditionally renders sidebar wrapper, adds bottom padding for mobile nav
- `index.css` removes `margin-left` on `.dashboard-main` at <600px

**Phase 2 — Spacing:**
- Main content padding: `p-3 xs:p-5` (12px at <480px, 20px at >=480px)
- Card padding: `card-base` class reduces to 16px at <480px via CSS
- Chronology item padding reduced at <480px

**Phase 3 — KPI Grid:**
- Moved grid-template-columns to `.kpi-grid` CSS class
- Single column at <360px, 2 columns otherwise
- KPI value font uses `clamp(22px, 6vw, 30px)`

**Phase 4 — Carousel:**
- 1 card per view at <480px
- Smaller min-height (148px) at <480px

**Phase 5 — Timeline:** Already wraps correctly (flexWrap: 'wrap' on header)

**Phase 6 — Constellation:** 380px height at <480px (was 520px)

**Phase 7 — Detail Panel:** Responsive padding (16px at <480px) via data attributes + CSS

**Phase 8 — Skills Grid:** Already single-column on mobile, no changes needed

### Extra fixes:
- Chat widget z-index bumped to 101 and bottom offset 72px at mobile (above bottom nav)
- Added `xxs: 360px` breakpoint to tailwind config

### Quality gates: All pass (lint 0 errors, typecheck clean, build succeeds)

## Code Review & Fixes — Iteration 3

### Issues found and fixed:
1. **Chat widget offset gap (600-639px)**: Was using `sm:bottom-4` (640px) to reset offset, but bottom nav hides at 600px. Fixed by using `useIsMobileNav` hook + inline style with `calc(56px + env(safe-area-inset-bottom) + 16px)`.
2. **Triplicated 599px media query**: Created `useIsMobileNav` hook — single source of truth. Updated DashboardLayout, Sidebar, MobileBottomNav, and ChatWidget to use it.
3. **Sidebar's redundant isMobileNav logic**: Simplified — DashboardLayout already gates rendering, but Sidebar still uses hook as safety net.
4. **Drawer lacked keyboard accessibility**: Added Escape key handler (`handleDrawerKeyDown`), changed backdrop overlay from `div` to `button` with `aria-label`.
5. **Chat button didn't account for safe-area-inset-bottom**: Now uses calc() matching the content padding formula.

### Not fixed (lower priority):
- TagPill/AlertFlag duplication between Sidebar and MobileBottomNav (cosmetic refactor)
- `xxs` breakpoint defined but unused (harmless)
- Nav item labels slightly different between Sidebar/MobileBottomNav (intentional — mobile uses shorter labels)

### Quality gates: All pass (lint 0 errors, typecheck clean, build succeeds)

## Ralph Coordinator — Iteration 4

### Event: build.blocked — Investigated and resolved

Received `build.blocked` event. Ran all three quality gates:
- `npm run lint` → 0 errors (6 warnings, all pre-existing)
- `npm run typecheck` → clean
- `npm run build` → succeeds

The build.blocked event appears stale — all gates pass. The implementation from iterations 1-3 is complete and clean.

### Code audit summary:
All changes verified across:
- `MobileBottomNav.tsx` — new bottom nav with drawer, keyboard accessible
- `useIsMobileNav.ts` — single source of truth for <600px breakpoint
- `DashboardLayout.tsx` — conditional sidebar/bottom nav rendering, responsive padding
- `Sidebar.tsx` — returns null at <600px
- `ChatWidget.tsx` — bottom offset accounts for mobile nav
- `index.css` — responsive CSS for margin-left, card padding, KPI grid, detail panel, chronology items
- `Card.tsx` — card-base class for responsive padding override
- `PatientSummaryTile.tsx` — KPI value font uses clamp()
- `ProjectsTile.tsx` — 1 card per view at <480px
- `useForceSimulation.ts` — 380px constellation height at <480px
- `tailwind.config.js` — xxs (360px) breakpoint added

Emitting `build.done` to trigger Visual Reviewer for screenshot validation.

## Ralph Coordinator — Iteration 5

### Events handled: build.task.abandoned + build.blocked (stale)

Re-verified all quality gates:
- `npm run lint` → 0 errors (6 warnings, pre-existing)
- `npm run typecheck` → clean
- `npm run build` → succeeds in 4.14s

### Full implementation verification:
Confirmed all 11 implementation items present and integrated:
1. DashboardLayout.tsx — MobileBottomNav imported, useIsMobileNav used, responsive padding
2. Sidebar.tsx — returns null at <600px
3. MobileBottomNav.tsx — 56px tab bar + Framer Motion drawer
4. useIsMobileNav.ts — single source of truth (max-width: 599px)
5. ChatWidget.tsx — bottom offset calc for mobile nav
6. index.css — all responsive CSS rules present
7. Card.tsx — card-base class applied
8. PatientSummaryTile.tsx — clamp(22px, 6vw, 30px) for KPI values
9. ProjectsTile.tsx — 1 card per view at <480px
10. useForceSimulation.ts — 380px height at <480px
11. tailwind.config.js — xxs: 360px breakpoint

### Task status: No open tasks remain.

All success criteria met. Emitting LOOP_COMPLETE.
