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.
