Install a statement recorder on the job's own database connection (Django connection.execute_wrapper) for the whole run and classify each statement it issues: reads pass, and writes must target a table on the allowlist. Fail closed on anything the classifier cannot read (for example a statement that contains an SQL comment), and on a sub-step that finishes with zero observed statements, since that suggests it ran on another connection or in another process. Keep the global before/after delta, but only as a report-only field so concurrent activity stays visible without stopping the job.
Proposed approach
Problem id
497f796e-2f87-4997-b9c4-79c658cc4de2
Proposed action
Wrap the run in connection.execute_wrapper, parse each statement's verb and target table, hard-stop only on a write outside the allowlist or an unreadable/unobserved statement, and demote the table-count delta to a report-only field.
