+"""Add debug_logging_run_count and error_notification_sent columns
+
+Revision ID: 0003
+Revises: 0002
+Create Date: 2026-05-03
+
+Changes:
+- debug_logging_run_count (INTEGER, default 0): counts completed/partial_failure
+  runs since debug_logging was last enabled.  Auto-disables debug_logging once
+  this counter reaches 5.  The counter is reset to 0 whenever debug_logging is
+  toggled back on via the API.
+
+- error_notification_sent (BOOLEAN, default FALSE): tracks whether a failure
+  notification has already been dispatched for the current consecutive error
+  streak.  Prevents notification spam: only the first failure in a streak fires
+  a notification.  Cleared (and a recovery notice sent) when a run succeeds.
