+# AI Modification Log: GitHub Output Date
+
+Date: 2026-06-29
+
+## Change
+
+- Replaced deprecated `::set-output` date output usage in X/Y/Z workflows with `$GITHUB_OUTPUT`.
+
+## Reason
+
+GitHub Actions deprecated `::set-output`. Writing `date=...` to `$GITHUB_OUTPUT` preserves the `steps.date.outputs.date` value using the supported output mechanism.
