*Migration completed through Phase 3 (with expandable tree) on October 18, 2025*
+
+---
+
+### Solution 5: Board Comparison Feature
+**Implemented**: October 19, 2025
+
+Migrated the complete board comparison functionality from JavaScript to PyScript:
+
+**Comparison Helper Functions** (in board_utils.py):
+- `compare_class_contents(class1, class2)` - Compares two classes for differences
+- `filter_class_to_show_differences(class1, class2)` - Filters class to show only unique items
+- `compare_module_contents(module1, module2)` - Compares two modules for differences
+- `filter_module_to_show_differences(module, other_module)` - Filters module to show only unique items
+
+**Main Comparison Functions**:
+- `compare_boards()` - Entry point that triggers async comparison
+- `_compare_boards_async()` - Async implementation with progress indicators
+- `get_board_modules(board)` - Fetches complete module data for a board
+- `update_comparison()` - Updates the comparison display
+- `calculate_comparison_stats(modules1, modules2)` - Calculates 3-level statistics
+- `render_comparison_modules(modules, other_modules, hide_common, is_board1)` - Renders comparison HTML
+
+**Features**:
+- Side-by-side comparison grid with color-coded headers (orange vs cyan)
+- Three-step loading progress (Step 1/2/3)
+- Comprehensive statistics table:
+ - Level 1: Modules (unique to each board, common)
+ - Level 2: Classes, Functions, Constants (differences in common modules)
+ - Level 3: Methods and Attributes (placeholder for future)
+- "Show only differences" checkbox to filter common modules
+- Dynamic filtering to show only modules/classes/functions with differences
+- Reuses board_utils.build_module_tree_html() for consistent rendering
+
+**UI Enhancements**:
+- Added checkbox control for "Show only differences"
+- Statistics panel with comprehensive 3-level comparison
+- Color-coded board headers (orange: board1, cyan: board2)
+- Board badges matching the header colors
+- Error handling with retry button
+
+**Code Changes**: +318 lines in board-explorer-mpy.html, +104 lines in board_utils.py
+
+*Comparison feature completed on October 19, 2025*
+
+---
+
+### Solution 6: API Search Feature
+**Implemented**: October 19, 2025
+
+Migrated the complete API search functionality from JavaScript to PyScript:
+
+**Search Functions**:
+- `search_apis()` - Entry point that triggers async search
+- `_search_apis_async()` - Async implementation with database queries
+- `display_search_results(query, results)` - Renders search results grouped by type
+
+**Search Capabilities**:
+- **Module Search**: Searches unique_modules table with LIKE query
+- **Class Search**: Searches unique_classes with module context
+- **Method/Function Search**: Searches unique_methods including module and class names
+- Case-insensitive partial matching using LOWER() and wildcards
+- Searches across ALL boards in the database
+- Limits method results to 10 per board for performance
+
+**UI Features**:
+- Loading spinner with search progress message
+- Results grouped by type (Modules, Classes, Methods/Functions)
+- Board badges showing which boards have matches
+- Count of unique boards with results
+- Styled result cards with icons
+- Enter key support for quick search
+- Empty state message when no results found
+
+**Database Queries**:
+```sql
+-- Module search
+SELECT DISTINCT um.name as module_name
+FROM unique_modules um
+JOIN board_module_support bms ON um.id = bms.module_id
+JOIN boards b ON bms.board_id = b.id
+WHERE b.port = ? AND b.board = ? AND LOWER(um.name) LIKE ?
+
+-- Class search
+SELECT DISTINCT um.name as module_name, uc.name as class_name
+FROM unique_classes uc
+JOIN unique_modules um ON uc.module_id = um.id
+JOIN board_module_support bms ON um.id = bms.module_id
+JOIN boards b ON bms.board_id = b.id
+WHERE b.port = ? AND b.board = ? AND LOWER(uc.name) LIKE ?
+
+-- Method search
+SELECT DISTINCT um.name as module_name, uc.name as class_name, umt.name as method_name
+FROM unique_methods umt
+JOIN unique_modules um ON umt.module_id = um.id
+LEFT JOIN unique_classes uc ON umt.class_id = uc.id
+JOIN board_method_support bms ON umt.id = bms.method_id
+JOIN boards b ON bms.board_id = b.id
+WHERE b.port = ? AND b.board = ? AND LOWER(umt.name) LIKE ?
+```
+
+**Code Changes**: +225 lines in board-explorer-mpy.html
+
+*Search feature completed on October 19, 2025*
+
+---
+
+## Final Migration Status
+
+### Completed Work (October 19, 2025)
+
+**Phase 1: Basic Page Setup** ✅
+- Created board-explorer-mpy.html with PyScript 2025.8.1
+- Implemented three-tab navigation (Explorer, Compare, Search)
+- Added status indicator for debugging
+- Copied and adapted CSS styling from original
+- Set up event handling system
+

+# PyScript Board Explorer - Testing Notes
+
+## Testing Environment Limitations
+
+The PyScript version cannot be fully tested in the current sandboxed CI environment because:
+- External CDN resources (PyScript, SQL.js) are blocked by ERR_BLOCKED_BY_CLIENT
+- PyScript requires these resources to initialize and execute Python code
+- Without PyScript loading, the JavaScript event handlers and Python functions cannot execute
+
+## HTML Structure Verification ✅
+
+The following has been verified in the HTML structure:
+
+### Compare Boards Tab
+- ✅ Board 1 Version dropdown (`id="board1-version"`)
+- ✅ Board 1 Board dropdown (`id="board1"`)
+- ✅ Board 2 Version dropdown (`id="board2-version"`)
+- ✅ Board 2 Board dropdown (`id="board2"`)
+- ✅ Compare button (`id="compare-btn"`)
+- ✅ "Show only differences" checkbox (`id="hide-common"`)
+- ✅ Compare stats container (`id="compare-stats"`)
+- ✅ Compare results container (`id="compare-results"`)
+
+### Search APIs Tab
+- ✅ Search input field (`id="search-input"`)
+- ✅ Search button (`id="search-btn"`)
+- ✅ Search results container (`id="search-results"`)
+
+### Navigation
+- ✅ Three-tab navigation (Board Explorer, Compare Boards, Search APIs)
+- ✅ Tab buttons with proper IDs and event handlers
+
+## Code Implementation Verification ✅
+
+The following has been verified in the source code:
+
+### Comparison Functions
+- ✅ `compare_boards()` - Entry point for comparison
+- ✅ `_compare_boards_async()` - Async implementation with progress indicators
+- ✅ `get_board_modules(board)` - Fetches complete module data
+- ✅ `update_comparison()` - Updates comparison display
+- ✅ `calculate_comparison_stats()` - Calculates 3-level statistics
+- ✅ `render_comparison_modules()` - Renders side-by-side comparison
+
+### Search Functions
+- ✅ `search_apis()` - Entry point for search
+- ✅ `_search_apis_async()` - Async implementation with database queries
+- ✅ `display_search_results()` - Renders grouped search results
+
+### Helper Functions in board_utils.py
+- ✅ `compare_class_contents(class1, class2)`
+- ✅ `filter_class_to_show_differences(class1, class2)`
+- ✅ `compare_module_contents(module1, module2)`
+- ✅ `filter_module_to_show_differences(module, other_module)`
+
+### Event Handlers
+- ✅ Compare button click handler: `document.getElementById("compare-btn").onclick = lambda e: compare_boards()`
+- ✅ Hide common checkbox handler: `document.getElementById("hide-common").onchange = lambda e: update_comparison()`
+- ✅ Search button click handler: `document.getElementById("search-btn").onclick = lambda e: search_apis()`
+- ✅ Search input Enter key handler: `document.getElementById("search-input").onkeypress = search_on_enter`
+
+## JavaScript Version Baseline Testing ✅
+
+The JavaScript version (board-explorer.html) was tested as a baseline and confirmed working:
+
+### Board Explorer Tab
+- ✅ Navigation tabs functional
+- ✅ Board selection dropdowns populate with data (using JSON fallback)
+- ✅ UI renders correctly
+
+### Compare Boards Tab
+- ✅ Tab switches correctly
+- ✅ Board 1 and Board 2 dropdowns present
+- ✅ "Show only differences" checkbox present
+- ✅ Compare button present
+- ✅ Share button present
+
+### Search APIs Tab
+- ✅ Tab switches correctly
+- ✅ Search input field present
+- ✅ Search button present
+- ✅ Share button present
