 ## Versioning & Releases

 Uses prefixed tags:
- `api/v0.3.0` → Triggers API Docker build
- `cli/v0.1.0` → Triggers CLI build (future)
+- `api/vX.Y.Z` → Triggers API Docker build
+- `cli/vX.Y.Z` → Triggers CLI build (future)
+
+### MANDATORY Release Procedure
+
+**NEVER push a tag before updating version files.** Follow this exact order:

 ```bash
-# API release
-cd webber-api
-# Update version in pyproject.toml
-git add -A && git commit -m "chore: release api v0.3.0"
-git tag api/v0.3.0
+# 1. Update version in pyproject.toml
+# 2. Update CHANGELOG.md with release notes
+# 3. Commit the version bump
+git add -A && git commit -m "chore: release api vX.Y.Z"
+
+# 4. Create the tag (AFTER the commit)
+git tag api/vX.Y.Z
+
+# 5. Push everything together
 git push origin main --tags
 ```

+**Why this matters:** Pushing a tag before the version commit requires deleting and recreating the tag, which can trigger CI/CD pipelines prematurely and cause deployment issues.
