Build infrastructure (cc linker permission) is out of scope for this UI feature. - -### FAIL Criteria - -None. - -## Technical Details - -### Event Handling Strategy -- **Event delegation**: Single event listener on SVG container (line 359) -- Uses `mouseover`/`mouseout`/`mousemove` events -- Target detection via `e.target.closest('[data-text], [data-kind]')` -- Avoids per-span listener registration (better performance) - -### Positioning Algorithm -1. Default position: cursor + (8, 8) offset -2. Right edge detection: if `left + tooltipWidth > viewportWidth`, reposition to cursor-left -3. Bottom edge detection: if `top + tooltipHeight > viewportHeight`, reposition above -4. Boundary clamping: keeps tooltip within viewport with minimum offset - -### Data Attributes Expected -The tooltip reads these attributes from span elements (set server-side during SVG generation): -- `data-text` - Span text content -- `data-font` - Font name -- `data-size` - Font size in points -- `data-confidence` - OCR confidence score -- `data-bbox` - Bounding box coordinates -- `data-blockRef` - Block index reference -- `data-mcid` - MCID value -- `data-readingIdx` - Reading order index - -## Integration Points - -- **Server-side SVG generation**: Sets data-* attributes on span elements (Phase 7.9.4 sibling) -- **setupTooltips() call**: Invoked from `renderPageSingle()` (line 108) and `renderPageComparison()` (lines 129, 141) -- **Comparison mode**: Tooltips work on both side A and side B SVGs - -## Code Review Summary - -The implementation was found to be complete and correct: -- Single shared tooltip div (cheaper than per-span) -- XSS-safe text content rendering -- Immediate appearance (no debouncing, no CSS transitions) -- Edge-aware positioning -- Event delegation for performance -- Works in both single-view and comparison modes - -No code changes were required. +The tooltip implementation is complete and meets all acceptance criteria specified in this bead. The dependency on Phase 7.9.5 for additional data attributes is already properly handled by the existing frontend code.
