Purpose
To maintain a clear, historical record of all component updates, ensuring traceability, accountability, and rollback capability.
1. When to Use
- New component created → must be logged.
- Component updated → log change reason + version tag.
- Component deprecated/removed → log with migration path.
2. Workflow Context
- Designer proposes change → fills log entry.
- Peer & Lead review → approve/reject.
- Dev Lead is notified if code impact exists.
- Entry becomes part of the Design System Changelog.

- Action → Created, Updated, Deprecated, Hotfix.
- Reason → Business, token change, UX feedback, dev request, QA bug.
- Impact →
- Low = non-breaking (cosmetic)
- Medium = new variant/feature, consumers unaffected
- High = breaking change, migration required
- Version → Must follow version control (vX.Y).
- Notes / Migration Path → Explicit replacement instructions.
5. Governance
- Entries cannot be skipped → no undocumented changes allowed.
- Only the Design Lead can mark final approval.
- Monthly review meeting → scan logs for recurring issues (e.g., too many hotfixes).
6. Usage Notes
- Store log in shared folder:
Design System → Component Logs. - Sync entries into the master Changelog Doc for dev + QA reference.
- Old entries are archived after 1 year but never deleted.
