# 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
