+# BUG-003: Clock start pile
+
+Clock can be started from any pile, but it should only start from the center pile.
+
+## Summary
+
+The Clock game currently allows the first move to begin from any pile, which
+breaks the rules and makes the game trivial to start incorrectly.
+
+This bug needs to enforce that the first card reveal must come from the center
+pile. Only after the center pile has started should the normal click flow apply.
+
+## Acceptance Criteria
+
+- [ ] The first click must be the center pile
+- [ ] Clicking a non-center pile before the game starts does nothing
+- [ ] After the center pile starts, normal clicking rules apply
+- [ ] Tests written and passing (TDD)
+- [ ] No TypeScript errors
+- [ ] No console warnings

+
+## Notes
+
+Focus on rule enforcement and UI behavior; avoid changes to unrelated logic.
