+# pdftract-5ec94: Hover tooltips, JSON-tree click navigation, search filter UI
+
+## Summary
+
+All three required features were already implemented in the frontend code:
+
+### 1. Hover tooltips (50 ms requirement)
+- **Implementation:** `setupTooltips()` in `app.js` (lines 594-671)
+- **CSS:** `transition:opacity 0s` in `style.css` line 45 - instant appearance, no delay
+- **Content displayed:** Text, Font (name + size), Confidence, BBox, Block ref, MCID, Reading idx
+- **Data source:** `data-*` attributes populated server-side in SVG rendering
+
+### 2. JSON-tree click navigation
+- **Span click handler:** `handleSpanClick()` (lines 344-371)
+- **Setup:** `setupJsonNavigation()` (lines 335-342)
+- **Behavior:**
+  - Clicking a span scrolls the JSON panel to the matching entry
+  - Adds `.highlighted` class (yellow background) for 2 seconds
+  - Opens parent `<details>` elements to reveal the entry
+  - Smooth scroll animation
+
+### 3. Search filter UI
+- **Setup:** `setupSearch()` (lines 469-482)
+- **Filtering:** `performSearch()` (lines 484-518) - case-insensitive substring match
+- **Cycling:** `cycleMatch()` (lines 520-537) - Enter cycles forward, Shift+Enter cycles backward
+- **Clearing:** `clearSearch()` (lines 556-561) - Escape key clears filter
+- **Visual feedback:**
+  - `.search-match` class adds bright orange outline (2px solid #ff9800)
+  - Active match gets double outline (3px solid #ff6f00)
+  - Match count displayed (e.g., "3 of 7 matches")
+
+## Acceptance Criteria
+
+| Criterion | Status | Notes |
+|-----------|--------|-------|
+| Hover tooltip appears within 50 ms | ✅ PASS | CSS `transition:opacity 0s` - instant |
+| Click span -> JSON tree scrolls + highlights | ✅ PASS | `handleSpanClick()` with smooth scroll + 2s highlight |
+| Search filter narrows visible spans | ✅ PASS | `.search-match` class with bright outline |
+| Enter cycles through matches | ✅ PASS | `cycleMatch(1)` on Enter, `cycleMatch(-1)` on Shift+Enter |
+| Escape clears search | ✅ PASS | Keyboard handler + `clearSearch()` |
+| Tooltip content matches plan | ✅ PASS | Text, Font, Confidence, Bbox, Block, MCID, Reading idx |
+
+## Files Verified
+
+- `crates/pdftract-cli/src/inspect/frontend/index.html` - HTML structure with tooltip div, search input, match count span
+- `crates/pdftract-cli/src/inspect/frontend/app.js` - All JS handlers for hover, click, search
+- `crates/pdftract-cli/src/inspect/frontend/style.css` - CSS for tooltip (0s transition), search-match outline, highlighted animation
+
+## Conclusion
+
+Bead requirements were already satisfied by existing code. No new implementation needed.
