Admin: Broken Culture Posts Now Raise An Alert

Environment: Dev & QA
Published culture posts go bad quietly. Their media is hosted elsewhere and expires, and publishers delete, hide or region-lock posts days after we schedule them. Nothing raised a flag, so the first sign of a broken card was always a person noticing — which is how 47 of 49 published carousel frames went bad before anyone spotted it.
Every published post is now checked on a schedule. When one stops displaying, the owners get a single email naming the post, explaining in plain terms what is wrong, and linking straight into the admin. Partly broken carousels are flagged too, because the rot spreads frame by frame and is cheapest to fix early. The check tries to repair a post before it alerts anyone, and no longer raises false alarms on healthy players.
