Diagnose Content API fallout after the cutover window.

Start with product writers, status readers, inventory jobs, queue workers, vendors, and platform apps.

Separate active production blockers from old migration notes so engineers can fix the right code first.

Search for Content API endpoints, customBatch, v1beta clients, old product ID builders, and status scripts.

Drain or disable stale queues before enabling migrated writers and record every NOT_VERIFIED path that still needs live validation.

After recovery, add CI scans and benchmark cases so stale Content API references do not return.
