# Session Changelog - December 11-12, 2025

## Summary of Changes

### 1. Fixed Decimal Number Sorting
- **Issue**: Job numbers with decimals (e.g., 3887.2) were sorting incorrectly, appearing before higher whole numbers (e.g., 4735)
- **Solution**: Replaced parseInt with parseFloat and used regex `/[0-9]+\.?[0-9]*/` to correctly extract and compare decimal job numbers
- **File**: Frontend/index.html
- **Function**: `jobNumberValue()`

### 2. Removed Premature Initial Render
- **Issue**: Cards were flashing with incorrect order during initial page load, then updating after full load completed
- **Solution**: Removed the `initialRendered` flag and early `applyFiltersAndRender()` call during the fetch loop
- **Result**: Cards no longer render until data is properly sorted and ready

### 3. Implemented Server-Side Sorting
- **Change**: Added `&sort=-Job_Number` parameter to PocketBase API query
- **Benefit**: Data arrives pre-sorted in descending order, eliminating client-side sort overhead
- **File**: Frontend/index.html
- **Function**: `fetchAllJobs()`

### 4. Implemented Progressive Loading (2-Phase)
- **Phase 1**: First 40 cards display immediately after first batch loads (~50 records from perPage=50)
- **Phase 2**: Remaining cards load in background and full list renders when complete
- **Benefit**: Users see meaningful content within 1-2 seconds instead of waiting for full dataset
- **File**: Frontend/index.html
- **Functions**: 
  - `fetchAllJobs()` - triggers render at 40 cards
  - `renderInitialBatch()` - renders first 40 cards immediately
  - `applyFiltersAndRender()` - renders complete sorted list after all data loaded

### 5. Expanded Cards Viewing Area
- **Change**: Converted layout to flexbox with `height:100vh` on body
- **Result**: Cards area now extends to bottom of screen, leaving only version footer visible
- **Improvements**:
  - Better use of screen real estate
  - More cards visible without scrolling
  - Cleaner full-screen experience
- **Files Modified**: Frontend/index.html
- **CSS Changes**:
  - `body`: Added `height:100vh`, `display:flex`, `flex-direction:column`, `overflow:hidden`
  - `.wrap`: Changed to `display:flex`, `flex-direction:column`, `flex:1`, `overflow:hidden`, removed margin
  - `#results`: Changed `max-height:56vh` to `flex:1` for dynamic expansion

## Performance Improvements
- **Perceived Load Time**: ~1-2 seconds for first 40 cards (was waiting for full load)
- **Search/Filter Responsiveness**: Now uses server-side sort, reducing client-side computation
- **Memory**: Progressive loading means full dataset isn't necessarily all rendered at once

## Files Modified
- Frontend/index.html (primary changes)
- No backend or configuration changes required

## Testing Notes
- Decimal job numbers (e.g., 3887.2, 4735) now sort correctly in descending order
- Initial page load shows first 40 cards immediately
- Remaining pages load in background with progress bar indication
- Full list renders with all filters/search applied once complete
