 - [x] Device detection proof of concept (File System Access API)
 - [x] Serial prefix → model mapping (verified against official Kobo help page)
-- [x] Architecture planning (updated: fully client-side, no PHP backend)
+- [x] Architecture planning (fully client-side WASM, no backend)
 - [x] Installed Go via Homebrew (v1.26.1)
-- [x] Verified all kobopatch tests pass natively
-- [x] Verified all kobopatch tests pass under `GOOS=js GOARCH=wasm` (via Node.js)
-- [x] Updated device identification doc with correct model list
-- [x] Removed obsolete backend-api.md
+- [x] Verified all kobopatch tests pass natively + WASM
 - [x] Created `kobopatch-wasm/` with setup.sh, build.sh, go.mod, main.go
 - [x] WASM wrapper compiles successfully (9.9MB)
-- [x] All kobopatch tests still pass with our module's replace directives
-- [x] Cleaned up .gitignore
+- [x] GitHub/Gitea CI workflow (build + test)
+- [x] Patch UI: loads patches from zip, parses YAML, renders toggles
+- [x] PatchGroup mutual exclusion (radio buttons)
+- [x] Full app flow: connect → detect → configure patches → upload firmware → build → write/download
+- [x] Patches served from `src/public/patches/` with `index.json` for version discovery
+- [x] JSZip for client-side zip extraction
+- [x] Renamed `src/frontend` → `src/public` (webroot)
+- [x] Moved `patches/` into `src/public/patches/`
 
-## In Progress
+## To Test
 
-### Integration Testing
+- [ ] End-to-end test in browser with real Kobo device + firmware zip
+- [ ] Verify WASM loads and `patchFirmware()` works in browser (not just Node.js)
+- [ ] Verify patch YAML parser handles all 6 patch files correctly
+- [ ] Verify File System Access API write to `.kobo/KoboRoot.tgz`
+- [ ] Verify download fallback works
 
-- [ ] Test WASM binary in actual browser (load wasm_exec.js + kobopatch.wasm)
-- [ ] Test `patchFirmware()` JS function end-to-end with real firmware zip + patches
+## Remaining Work
 
-### Frontend - Patch UI
-
-- [ ] YAML parsing in JS (extract patch names, descriptions, enabled, PatchGroup)
-- [ ] `patch-ui.js` — render grouped toggles per target file
-- [ ] PatchGroup mutual exclusion (radio buttons)
-- [ ] Generate kobopatch.yaml config string from UI state
-
-### Frontend - Build Flow
-
-- [ ] User provides firmware zip (file input / drag-and-drop)
-- [ ] Load WASM, call `patchFirmware()` with config + firmware + patch files
-- [ ] Receive KoboRoot.tgz blob, write to `.kobo/` via File System Access API
-- [ ] Fallback: download KoboRoot.tgz manually
-- [ ] Bundle patch YAML files as static assets
+- [ ] Copy `kobopatch.wasm` + `wasm_exec.js` to `src/public/` as part of build
+- [ ] Run WASM patching in a Web Worker (avoid blocking UI during build)
+- [ ] Loading/progress feedback during WASM load + build
+- [ ] Better error messages for common failures
+- [ ] Test with multiple firmware versions / patch zips
 
 ## Future / Polish
 
-- [ ] Run WASM patching in a Web Worker (avoid blocking UI)
-- [ ] Browser compatibility warning with detail
-- [ ] Loading/progress states during build
-- [ ] Error handling for common failure modes
 - [ ] Host as static site (GitHub Pages / Netlify)
-- [ ] NickelMenu install/uninstall support (bonus feature)
+- [ ] NickelMenu install/uninstall support
+- [ ] Dark mode support
 
 ## Architecture Change Log
 
 - **Switched from PHP backend to fully client-side WASM.**
   Reason: avoid storing Kobo firmware files on a server (legal risk).
-  The user provides their own firmware zip. kobopatch runs as WASM in the browser.
-  No server needed — can be a static site.
+- **Patches served from zip files in `src/public/patches/`.**
+  App scans `patches/index.json` to find compatible patch zips for the detected firmware.
+  User provides their own firmware zip. kobopatch runs as WASM in the browser.
