# Web Matcher Filter Enablement — Implementation Report

Date: 2026-04-20

## Changes

### index.html
- Removed `disabled` attribute from 16 checkbox inputs (lines 81-83, 90, 97-100, 107-110, 117-120)
- Removed `filter-disabled` CSS class from 5 filter-group wrapper divs (lines 78, 87, 94, 104, 114)
- Removed `title="Coming soon"` from those same 5 divs
- Added "Unknown" checkbox to Energy filter group (checked by default, matching kids/dogs/cats pattern)

### app.js
- Updated energy filter in `applyFilters()` to use the same unknown-handling pattern as compatibility filters:
  - Before: unknown/missing energy → always excluded
  - After: unknown/missing energy → included if "Unknown" checkbox is checked (default)

## Energy Unknown Checkbox HTML
```html
<label class="checkbox-label"><input type="checkbox" name="energyLevel" value="unknown" checked> Unknown</label>
```

## Verification
- disabled count: 0
- filter-disabled count: 0
- "Coming soon" count: 0
- HTML parsed OK
- JS syntax OK
- HTTP 200 on matcher URL
- Served HTML has 0 disabled attributes
