docs: Update debug memory with current status and next steps

- WebAssembly compilation error still persisting despite multiple fixes
- Root cause: sqljs.worker.js contains incorrect double ./ path
- Issue: Webpack plugin regex not matching minified worker file content
- Added comprehensive prompt for next chat session
- Documented all attempted fixes and current file status
- Ready for next debugging session with clear action plan

 # SQL.js WASM Debug Memory
 
 ## Current Issue
-- WebAssembly compilation error still occurring
+- WebAssembly compilation error STILL occurring despite multiple fixes
 - Error: `CompileError: WebAssembly.instantiate(): expected magic word 00 61 73 6d, found 3c 21 44 4f @+0`
-- Root cause: SQL.js trying to load `/sql-wasm.wasm` (404 error)
+- Error location: `sql-wasm.js:159` - wasm streaming compile failed
+- Root cause: SQL.js worker trying to load WASM file from incorrect path
 
 ## Progress Made
 - ✅ Fixed `981.js` chunk file - path changed from `.././sql-wasm.wasm` to `./sql-wasm.wasm`
 - ✅ Webpack plugin is working and finding files
-- ❌ Still getting 404 error for `/sql-wasm.wasm`
+- ✅ Added `sql-wasm.js` to CopyWebpackPlugin - file now available (200 status)
+- ✅ Added `sqljs.worker.js` to CopyWebpackPlugin - file now available (200 status)
+- ❌ Still getting WebAssembly compilation error
 
 ## Current Investigation
-- There are multiple SQL.js files in the build
-- `981.js` was fixed but there's another file (`870.js`) still trying to load from root path
-- Found the same pattern in `870.js`: `locateFile:t=>".././sql-wasm.wasm"`
-- Webpack plugin is working but not catching all files
-- **ROOT CAUSE FOUND**: Error is coming from `sql-wasm.js:159` - this is a separate `sql-wasm.js` file that's being loaded dynamically
-- The `sql-wasm.js` file exists in node_modules but is NOT being copied to build output
-- **SOLUTION**: Add `sql-wasm.js` to CopyWebpackPlugin to copy it to build output
-- **NEW ROOT CAUSE**: The `sqljs.worker.js` file is missing (404 error) - this is the actual worker script that SQLDelight needs
-- **FINAL SOLUTION**: Add `sqljs.worker.js` to CopyWebpackPlugin to copy the worker script
-- **ACTUAL ROOT CAUSE**: The `sqljs.worker.js` file contains `locateFile:e=>"././sql-wasm.wasm"` (double ./) which is incorrect
-- **FINAL FINAL SOLUTION**: Update webpack plugin to fix the double ./ pattern in worker files
-
-## Files Found
+- **ROOT CAUSE IDENTIFIED**: The `sqljs.worker.js` file contains `locateFile:e=>"././sql-wasm.wasm"` (double ./) which is incorrect
+- **PROBLEM**: Webpack plugin is NOT fixing the double ./ pattern in the worker file
+- **EVIDENCE**: Deployed `sqljs.worker.js` still contains `locateFile:e=>"././sql-wasm.wasm"` despite webpack plugin processing it
+- **WEBPACK LOGS**: Plugin processes worker file but reports "Before fix - locateFile pattern found: false"
+- **ISSUE**: Regex pattern `/locateFile:e=>"\.\/\.\/sql-wasm\.wasm"/g` is not matching the minified content
+
+## Files Status
 - ✅ `981.js` - Fixed (path changed from `.././sql-wasm.wasm` to `./sql-wasm.wasm`)
+- ✅ `sql-wasm.js` - Available (200 status)
+- ✅ `sqljs.worker.js` - Available (200 status) but contains INCORRECT path
 - ❌ `870.js` - Still has `.././sql-wasm.wasm` pattern (webpack plugin not processing distribution files)
-- ✅ `sql-wasm.js` - Now copied to build output
-- ❌ `sqljs.worker.js` - Missing from build output, needs to be copied by webpack plugin
 
-## Next Steps
-1. Update webpack plugin to catch all chunk files including 870.js
-2. Test the fix
-3. Verify all SQL.js files are processed
+## Current Attempts
+1. ✅ Added `sql-wasm.js` to CopyWebpackPlugin
+2. ✅ Added `sqljs.worker.js` to CopyWebpackPlugin  
+3. ✅ Added regex pattern for double ./ in worker files
+4. ❌ **CURRENT ISSUE**: Regex pattern not matching minified worker file content
+
+## Next Steps for Next Chat
+1. **IMMEDIATE**: Fix the regex pattern in webpack plugin to match the exact minified content
+2. **INVESTIGATE**: Check if webpack minimization is changing the pattern structure
+3. **ALTERNATIVE**: Try a more general regex pattern that catches the double ./ regardless of variable name
+4. **TEST**: Verify the fix works by checking deployed worker file content
+5. **FALLBACK**: Consider modifying the worker file source before webpack processing
+
+## Technical Details
+- **Deployed URL**: https://softartdev.github.io/NoteDelight/
+- **Current Branch**: `web`
+- **Worker File Content**: `locateFile:e=>"././sql-wasm.wasm"` (INCORRECT)
+- **Expected Content**: `locateFile:e=>"./sql-wasm.wasm"` (CORRECT)
+- **Webpack Plugin**: Processing worker file but regex not matching
 
 ## Important Reminder
 - **Cancel KMP workflow after each push to "web" branch** to save resources
 - Use: `gh run cancel <RUN_ID>` (see gh_cheat_sheet.md for reference)

+I'm debugging a WebAssembly compilation error in a Kotlin Multiplatform web app. The error is:
+
+`CompileError: WebAssembly.instantiate(): expected magic word 00 61 73 6d, found 3c 21 44 4f @+0`
+
+**ROOT CAUSE**: The `sqljs.worker.js` file contains `locateFile:e=>"././sql-wasm.wasm"` (double ./) which is incorrect and should be `locateFile:e=>"./sql-wasm.wasm"`.
+
+**CURRENT STATUS**: 
+- Webpack plugin is processing the worker file but the regex pattern `/locateFile:e=>"\.\/\.\/sql-wasm\.wasm"/g` is not matching the minified content
+- Deployed worker file still contains the incorrect path despite webpack plugin running
+- All required files (sql-wasm.wasm, sql-wasm.js, sqljs.worker.js) are available (200 status)
+
+**IMMEDIATE TASK**: Fix the webpack plugin regex pattern to correctly match and replace the double ./ pattern in the minified worker file.
+
+**FILES TO CHECK**:
+- `app/web/webpack.config.d/sqljs-config.js` - webpack plugin configuration
+- Deployed worker file: https://softartdev.github.io/NoteDelight/sqljs.worker.js
+
+**WORKFLOW**: 
+1. Fix regex pattern in webpack plugin
+2. Commit and push to `web` branch
+3. Cancel any running KMP workflows
+4. Wait for deployment
+5. Test the fix
+
+Please help me fix the regex pattern to correctly match the minified worker file content.
