# Progress Log — Clinical Record PMR Phase

## Phase Transition

**Previous phase completed:** React conversion of ECG Heartbeat CV (all 12 tasks done)
**New phase started:** Clinical Record PMR System — Design 7 implementation
**Date:** 2026-02-11

This is a complete redesign of the CV presentation, moving from the ECG animation concept to a Patient Medical Record system interface. All previous components (Hero, Skills, Experience, etc.) will be replaced with PMR-specific views and components.

## Codebase Patterns

### PMR Design System
- **Source of truth**: `designs/07-the-clinical-record.md` — Complete specification for the PMR interface
- **Color palette (light-mode only)**:
  - Main content: `#F5F7FA` (cool light gray)
  - Cards: `#FFFFFF` (white)
  - Sidebar: `#1E293B` (dark blue-gray)
  - Patient banner: `#334155` (lighter blue-gray)
  - NHS blue: `#005EB8` (primary interactive)
  - Green: `#22C55E` (active/resolved)
  - Amber: `#F59E0B` (alerts/in-progress)
  - Red: `#EF4444` (urgent)
  - Borders: `#E5E7EB` (gray-200)
- **Typography**: Inter for general text, Geist Mono for coded entries/data values
- **Spacing**: 4px base unit, tighter than previous design (clinical system density)
- **Borders**: 1px solid gray-200, 4px radius (clinical systems use minimal rounding)
- **Table rows**: 40px height, alternating colors

### Data Architecture
- All PMR content lives in `src/data/` as typed arrays
- Separation of data from components enables easy CV updates
- Types defined in `src/types/pmr.ts`

### Animation Approach
- **Login typing**: `setInterval` with character-by-character reveal (30ms/char username, 20ms/dot password)
- **View switching**: Instant (no animation) — matches clinical system behavior
- **Consultation expand**: Height 0→auto, 200ms, ease-out
- **Alert entrance**: Slide down with spring, 250ms
- **Alert dismiss**: Icon → checkmark (200ms) → collapse (200ms)
- **Patient banner condensation**: Smooth height transition, 200ms
- **Reduced motion**: Typing instant, slides become fades, expand instant

### Clinical System Authenticity
- Navigation is instant — no crossfade
- Tables use explicit borders on all cells
- Traffic lights are 8px circles with text labels (never sole indicator)
- Consultation format: History / Examination / Plan (clinical SOAP note structure)
- Medications table mimics actual prescribing lists
- Coded entries use [XXX000] format (SNOMED-style)

### Responsive Breakpoints
- Desktop (>1024px): 220px sidebar, full tables
- Tablet (768-1024px): 56px icon-only sidebar, scrollable tables
- Mobile (<768px): Bottom nav bar, card layouts instead of tables

### Accessibility Requirements
- Tables must be proper `<table>` markup with `scope="col"`
- Clinical alert uses `role="alert"` and `aria-live="assertive"`
- Keyboard shortcuts: Alt+1-7 for navigation
- Focus management after view changes and expansions
- Screen reader announces views and table structure

## Iteration Log

### Iteration 1 — Task 1: Create PMR data layer and TypeScript types
- **Completed**: Task 1 - Created PMR data layer with TypeScript interfaces and data files
- **Files created**:
  - `src/types/pmr.ts` - All PMR TypeScript interfaces (Patient, Consultation, Medication, Problem, Investigation, Document, etc.)
  - `src/data/consultations.ts` - 5 roles mapped to consultation format with History/Examination/Plan structure
  - `src/data/medications.ts` - 18 skills mapped to medication format across 3 categories (Active, Clinical, PRN)
  - `src/data/problems.ts` - 11 problems with traffic light status (3 Active, 2 In Progress, 6 Resolved)
  - `src/data/investigations.ts` - 5 projects as investigations with methodology/results
  - `src/data/documents.ts` - 5 education/certification documents
  - `src/data/patient.ts` - Patient demographic data
- **Design decisions**:
  - Used SNOMED-style codes for coded entries (EFF001, ALG001, AUT001, etc.)
  - Mapped employer colors: NHS blue (#005EB8) for ICB, Teal (#00897B) for Tesco
  - Proficiency percentages estimated from CV skill descriptions
  - Prescribing history for each skill shows progression over time
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - CV has 5 roles but only 4 explicitly listed dates - inferred Duty Pharmacy Manager from GPhC registration date (Aug 2016)
  - Key numbers verified: £14.6M efficiency, 14,000 patients, £2.6M savings, 70% reduction, 200 hours, £1M revenue, £220M budget
  - Skills categorized into Active (technical), Clinical (healthcare domain), PRN (strategic/leadership)

### Iteration 2 — Task 2: Modify ECGAnimation for PMR flatline transition
- **Completed**: Task 2 - Modified ECGAnimation exit phase for clinical flatline → login transition
- **Files modified**:
  - `src/components/ECGAnimation.tsx` - Changed exit from fade-to-white to flatline → black → login background
- **Changes made**:
  - Replaced HOLD_TIME (0.75s) and EXIT_TIME (0.8s) with precise phase timings:
    - FLATLINE_HOLD: 300ms (hold after name trace)
    - FLATLINE_DRAW: 300ms (horizontal line extending rightward)
    - FADE_TO_BLACK: 200ms (canvas opacity fade)
    - BG_TRANSITION: 200ms (background to #1E293B login color)
  - New timing phases: isFlatlinePhase, isFadePhase, isBgTransitionPhase
  - Background now transitions to login screen color (#1E293B) instead of white
  - Flatline drawn from final name position to right edge of viewport
  - Scanline head dot hidden during fade/bg phases
- **Design decisions**:
  - Flatline visually reads as patient monitor flatline (deliberate metaphor)
  - Total ECG phase still ~5-6 seconds, exit adds ~1 second
  - Background transition uses CSS transition for smooth handoff to LoginScreen
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - Canvas fade must complete before background transition for clean visual
  - The flatline extension needs to go slightly past viewport edge (+50px) for smooth visual

### Iteration 3 — Task 3: Build LoginScreen component with typing animation
- **Completed**: Task 3 - Created LoginScreen component with authentic clinical login typing animation
- **Files created/modified**:
  - `src/components/LoginScreen.tsx` - New component with typing animation
  - `src/App.tsx` - Added 'login' phase between 'ecg' and 'content'
  - `src/types/index.ts` - Added 'login' to Phase type
  - `index.html` - Added Inter font family
  - `tailwind.config.js` - Added PMR colors (sidebar, banner, nhsblue, etc.) and fonts (inter, geist)
- **Design decisions**:
  - Username types at 30ms per character (A.CHARLWOOD = 11 chars + space = ~350ms)
  - Password fills 8 dots at 20ms per dot (~160ms)
  - Button shows pressed state (darker, scale) before onComplete callback
  - Blinking cursor at 530ms interval during typing
  - Uses Fira Code as monospace font (Geist Mono not available via Google Fonts)
  - NHS blue shield icon for clinical system branding
  - White login card: 320px wide, 12px radius, subtle shadow
- **Accessibility**:
  - Respects prefers-reduced-motion: instant text appearance, ~500ms total
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - Geist Mono not available via Google Fonts, using Fira Code as fallback
  - Total login animation timing: ~1.2s (350ms username + 150ms pause + 160ms password + 150ms pause + 100ms button + 200ms hold)

### Iteration 4 — Task 4: Build PatientBanner component with full and condensed modes
- **Completed**: Task 4 - Created PatientBanner component with scroll-based condensation
- **Files created**:
  - `src/hooks/useScrollCondensation.ts` - IntersectionObserver hook for scroll detection

  - Proper link semantics for phone and email
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - IntersectionObserver with rootMargin provides cleaner scroll detection than scroll event listeners
  - Sentinel element at top of viewport triggers condensation when it leaves view
  - Sticky positioning requires no JavaScript for the sticky behavior itself

  - URL hash routing (#summary, #consultations, etc.)
  - Keyboard shortcuts: Alt+1-7 for navigation, / to focus search, Escape to clear search
- **Navigation behavior**:
  - Instant view switching (no animation) — matches clinical system authenticity
  - Click updates URL hash and activeView state simultaneously
  - On page load, hash is read to set initial view
- **Accessibility**:
  - `role="navigation"` and `aria-label` on sidebar
  - `aria-current="page"` on active nav item
  - Keyboard navigation with Alt+1-7 shortcuts
  - Search has escape key to clear and blur
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - Lucide React already installed, provides all required icons
  - fuse.js not installed — basic search filtering implemented, can enhance later
  - Sticky positioning with `h-screen sticky top-0` keeps sidebar fixed while content scrolls

  - Patient Demographics card: full width, two-column key-value layout with right-aligned labels
  - Active Problems card: shows 3 active/in-progress problems with traffic light dots and dates
  - Current Medications Quick View: 4-column table (Drug, Dose, Freq, Status), top 5 Active meds
  - Last Consultation card: shows most recent role with truncated history text
  - Traffic lights: 8px circles, green for Active/Resolved, amber for In Progress
  - All tables use proper semantic `<table>` markup with `scope="col"`
  - "View Full List" / "View Full Record" links navigate to corresponding views
- **Accessibility**:
  - `role="alert"` and `aria-live="assertive"` on Clinical Alert
  - `aria-label` on main content area with current view name
  - Proper table semantics for medications table
  - Traffic lights always accompanied by text labels (never sole indicator)
  - Respects `prefers-reduced-motion`: alert appears instantly, no animations
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - Alert animation uses max-height transition for smooth expand/collapse
  - Clinical Alert text uses amber-800 (#92400E) for contrast against amber-100 background
  - Grid layout: demographics full width, problems/medications side-by-side, last consultation full width
  - `line-clamp-2` and `line-clamp-3` utilities work well for truncating text in cards

### Iteration 7 — Task 7: Build ConsultationsView with History/Examination/Plan structure
- **Completed**: Task 7 - Created ConsultationsView with expandable consultation entries
- **Files created**:
  - `src/components/views/ConsultationsView.tsx` - Full Consultations view with 5 expandable entries
- **Files modified**:
  - `src/components/PMRInterface.tsx` - Added ConsultationsView to renderView switch
- **Design decisions**:
  - Each entry has 3px left border color-coded by employer: NHS blue (#005EB8) for ICB, Teal (#00897B) for Tesco
  - Collapsed state shows: status dot, date, organization (colored), role title, key coded entry summary
  - Status dot: green for current roles, gray for historical
  - Expanded state shows: Duration, HISTORY (paragraph), EXAMINATION (bullets), PLAN (bullets), CODED ENTRIES
  - Section headers styled in Inter 600, 12px, uppercase, tracking-wider, gray-400
  - Coded entries use [XXX000] format in Geist Mono, gray-400
  - Only one entry expanded at a time (accordion behavior)

  - Chevron icon rotates 180° when expanded
- **Accessibility**:
  - `aria-expanded` on toggle buttons
  - Status dots have `aria-label` describing current vs historical
  - Respects `prefers-reduced-motion`: expand is instant
- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
- **Learnings**:
  - Height animation uses `height: auto` which requires setting height to undefined after animation
  - Content inside expanded area uses separate opacity transition for smooth appearance
  - Border-left styling with explicit width/color in style prop for dynamic org colors
