## QA PASSED See QA report document: ae2aefcd-d27e-4063-93e8-427b3c166dbc **All verification checks passed:** - CSS class names match template exactly (20/20 classes) - No nested selectors that break styling - No old naming patterns remaining - All 24 attachment tests pass - Template structure matches CSS selectors **CSS Fix Applied:** Rewrote CSS at lines 1497-1703 in base.html to use flat BEM-style selectors matching template's class names exactly. Fix verified working. The attachment item template is ready for production use with both thumbnail and list rendering modes fully styled and functional.

## QA FAILED (Re-verification) See QA report document: b2723ba0-8859-4c32-8820-51aa523e62ab **Status of CSS Cleanup:** - Duplicate CSS removed: ✓ PASS - No duplicate definitions found at lines 802-1005 **Critical Issue Found:** - CSS class name mismatch: ✗ FAIL (CRITICAL) The CSS at lines 1497-1665 uses OLD nested naming convention: - `.attachment-thumbnail .attachment-info` - `.attachment-list-item .attachment-icon` - `.attachment-list-item .attachment-details` - `.attachment-list-item .attachment-name` But the template uses NEW flat BEM-style naming: - `.attachment-thumbnail-info` - `.attachment-list-icon` - `.attachment-list-content` - `.attachment-list-title` **Impact:** This is a complete styling failure. The template will render HTML but ALL styling will fail to apply. Thumbnails will have no info overlay, no hover effects, no download buttons. List items will have no icons, no layout, no hover effects. **Required Fix:** Rewrite CSS at lines 1497-1665 to use flat selectors matching the template's BEM-style class names. Returning to todo for CSS fixes.

## QA FAILED See QA report document: 24a9ece3-5f66-4c9f-b900-819d22c8fbd2 **Critical Issues Found:** 1. **Duplicate CSS definitions in base.html** (Critical) - Lines 803-1005 define correct styles matching template - Lines 1703-1820+ define conflicting styles with different class names - Later definitions override earlier ones, breaking visual rendering - CSS expects class names like `.attachment-info`, `.attachment-details`, `.attachment-name` which don't exist in template - Template uses `.attachment-thumbnail-info`, `.attachment-list-content`, `.attachment-list-title` which have no CSS in effect 2. **Archive mime_type detection incomplete** (Minor) - TAR files (`application/x-tar`) show generic icon instead of archive icon - Detection only checks for 'archive', 'compressed', 'zip' substrings - Misses: x-tar, x-rar-compressed, x-7z-compressed, etc. **Template Logic Verification: PASS** - No Jinja2 syntax errors - Dual rendering works (thumbnail for images, list for others) - Edge cases handled: None mime_type, empty mime_type, missing size_bytes - Owner info rendering works with issue_map/project_map - Template inclusion in parent templates works **Regression Testing: PASS** - No new test failures introduced - 1406/1408 tests passing (2 pre-existing failures unrelated to attachments) Returning to todo for CSS fixes.

## Implementation Complete Created `server/templates/partials/attachment_item.html` with dual rendering support. ### Files Changed: - **server/templates/partials/attachment_item.html** (new) - Main partial template with dual view modes - **server/templates/base.html** - Added CSS styles for attachment item components ### Features Implemented: **Thumbnail Gallery Mode** (for images): - Displays image preview with thumbnail - Shows title, subtitle, and file size - Hover-reveal download button - Error handling with placeholder icon if image fails to load **List Item Mode** (for files/URLs): - Icon based on file type (PDF, ZIP, video, audio, text, generic file, link) - Title, subtitle, and metadata display - File type badge and size display - Optional owner link display - Hover-reveal action buttons **Auto-detection:** - Automatically selects view mode based on `mime_type` (images use thumbnail, others use list) - Manual override available via `view_mode` parameter **Context Variables:** - `attachment` (required) - The attachment object - `view_mode` (optional) - Force 'thumbnail' or 'list' mode - `show_owner` (optional) - Whether to show owner info - `issue_map` / `project_map` (optional) - For owner link display ### CSS Classes Added: - `.attachment-thumbnail`, `.attachment-thumbnail-*` - Thumbnail gallery styling - `.attachment-list-item`, `.attachment-list-*` - List item styling - `.attachment-gallery` - Container for thumbnail grid - `.attachment-list` - Container for list layout ### Verification: - All existing tests pass (52 tests including attachment and web helper tests) - Deployed to trckr.roboalch.com
