## QA PASSED See QA report document: 271b22aa-57ae-4fcf-9b69-7aa7bb1e090c **Verification Summary:** - Code implementation verified in server/routes/web.py (lines 159-180) - Filter function properly implements regex matching with re.match() - Filter correctly registered with templates.env.filters - All 6 match filter tests PASS - All 90 server tests PASS (no regressions) - Handles edge cases (None values, complex patterns) **Test Results:** - test_match_filter_basic: PASSED - test_match_filter_mime_types: PASSED - test_match_filter_with_none: PASSED - test_match_filter_exact_match: PASSED - test_match_filter_complex_pattern: PASSED - test_match_filter_registered_in_templates: PASSED Feature is production-ready and approved.

## Implementation Complete Added the `match` Jinja2 filter for regex-based MIME type matching in templates. ### Changes Made **server/routes/web.py** (lines 159-180): - Added `_match_filter(value: str, pattern: str) -> bool` function that uses `re.match()` for regex matching - Handles `None` values gracefully (returns `False`) - Registered the filter with `templates.env.filters["match"] = _match_filter` ### Usage Example Templates can now use the filter with `selectattr`: ```jinja {# Filter attachments to only show images #} {% for attachment in attachments|selectattr('mime_type', 'match', '^image/')|list %} <img src="{{ attachment.url }}" /> {% endfor %} {# Filter for specific image types #} {% for attachment in attachments|selectattr('mime_type', 'match', '^image/(png|jpeg|gif)$')|list %} ... {% endfor %} ``` ### Test Coverage Added `TestJinja2MatchFilter` class in tests/test_server.py with 6 tests: - Basic matching functionality - Various MIME type patterns (image, text, application) - None value handling - Exact match patterns - Complex regex patterns with alternation - Filter registration verification ### Verification - All 1331 tests pass - Deployed to production at trckr.roboalch.com - Health check confirms server is running
