+-- Persist congestion requeue telemetry directly on remember_jobs so operators
+-- and status checks can inspect how many times a job was parked for upload
+-- congestion and when its next attempt is scheduled without decoding the
+-- Apalis payload or scraping logs.

+-- Both columns use metadata-only fast defaults in PostgreSQL 11+ and do not
+-- rewrite existing rows.
