+## v20260108-38-missed-run-grace-window
+
+- Adjusted missed run detection to respect a ±1 hour grace window around the scheduled run time.
+- Prevented runs that arrive shortly after the scheduled time (e.g. a few minutes late) from being temporarily marked as Missed.
+- Ensured Missed status is only applied after the full grace window has elapsed, avoiding false Missed entries in Run Checks and Daily Jobs.
