+name: Slack Ready-for-Review Digest
+
+# Sends one quiet digest at 7:00 AM Pacific on weekdays.
+# The window starts at the most recent successful scheduled run of this
+# workflow, so a failed run is self-healing and is covered by the next run.
+# If no successful scheduled run exists, Monday looks back 72 hours and every
+# other weekday looks back 24 hours. Manual runs can set lookback_hours to
+# override either behavior; set dry_run to build and log the payload without
+# posting it to Slack.
+#
+# MANUAL TESTING:
+# Use workflow_dispatch with lookback_hours (for example, 720 for 30 days) and
+# dry_run=true. The generated PR JSON and Slack payload are printed in logs.
