 ## CI & Release Workflow
 
-1. **On every push/PR**: CI runs lint, test, build
-2. **On PR**: Artifacts built for all platforms (downloadable for testing)
+1. **On push to main**: CI runs lint, test, build
+2. **On PR**: Lint, test, then GoReleaser snapshot builds for all platforms; posts a comment with download links
 3. **On merge to main with `feat:` or `fix:` commit**: Auto-release creates tag and triggers release
 4. **On tag push**: GoReleaser builds and publishes to GitHub Releases and Homebrew
