+## Gitea Runner and Release Workflow
+
+### Runner Configuration
+
+- **Image**: `hub.gaomia.site/titor/bun:latest` (based on Debian bookworm with Bun installed)
+- **Default label**: `ubuntu-latest`
+- **Issue**: Custom image doesn't have git pre-installed
+
+**Solution**: Install git in workflow:
+
+```yaml
+- name: Install git
+  run: apt-get update && apt-get install -y git
+```
+
+### Release Workflow (Auto-changelog)
+
+Trigger on push tag (`v*`):
+
+1. Clone repository using token
+2. Install dependencies: `bun install`
+3. Build: `bun run build`
+4. Create release and upload source archive:
+
+```bash
+TAG_NAME="${GITHUB_REF#refs/tags/}"
+PREV_TAG=$(git describe --tags --abbrev=0 HEAD^ 2>/dev/null || echo "")
+CHANGES=$(git log --pretty=format:"- %s (%h)" "$PREV_TAG..HEAD" 2>/dev/null || echo "")
+
+# Create release via Gitea API
+curl -X POST "https://hub.gaomia.site/api/v1/repos/titor/mio/releases" \
+  -H "Authorization: token ${GITEA_TOKEN}" \
+  -d "{\"tag_name\":\"${TAG_NAME}\",\"name\":\"${TAG_NAME}\",\"body\":\"${CHANGES}\"}"
+```
+
+### Cross-platform Build Limitation
+
+- Bun's `bun build --compile` runs on Linux runner → can only produce Linux executable
+- Cannot compile Windows/macOS binaries on Linux environment
+- Workaround: Publish source code archive instead of binaries
+
+### Bun Compilation Bug with Native Modules
+
+**Problem**: Using `@libsql/client` (native SQLite binding) causes runtime error:
+```
+error: Cannot find module '@libsql/win32-x64-msvc' from 'B:\~BUN\root\mio.exe'
+```
+
+This is a known bug in Bun 1.3.4+ with native modules.
+
+**Solution**: Replace `@libsql/client` with `sql.js` (pure JavaScript SQLite implementation):
+
+1. Replace dependency in package.json
+2. Rewrite db.ts to use sql.js API (async initialization, different query syntax)
+3. Update all function calls in index.tsx and NoteEditor.tsx
+
+Result: `bun build --compile` works correctly on all platforms.
