Use when you see this exact failure: parser…

agent cannot parse SCIM user export with null managers: parsing failed with error and the workflow broke

Fixes an agent run that fails parsing the SCIM user export with null managers during access review work, by diagnosing the file structure, quarantining bad records and validating parsed output against source counts. Use when parsing, not the platform API, is what breaks the run. Not for files that parse cleanly but co…

Recovery when an agent's idempotency check read the wrong state table (flyway_schema_history instead of alembic_version): reconciling the real state and fixing the agent's procedure to check the tool the app actually uses. Use when a migration was skipped or double-applied because the agent consulted the wrong history…
