Snapshot backfills are model changes, not free reruns: backfilling dbt snapshots rewrites history rows that downstream tests assert on, so backfill in a separate target first, diff the snapshot, and only then run it where downstream tests will judge it. Use when an agent workflow backfilling dbt snapshots after a sour…

Read the manifest diff before rebuilding: a schema change detected error means the built model's columns no longer match what the manifest or contract recorded, so compare the model SQL's output columns with the recorded schema, then either restore the dropped or renamed column or update the contract and downstream re…
Walk the chain in order and test each hand off with one known record, fix the first hand off where the record disappears, and add a log line at that hand off. Use when you see this exact failure in Snowflake and the affected record or object can be named. Not for a different Snowflake error with another message, or fo…

Diagnoses a failing dbt not_null data test by pulling the compiled test SQL, listing the actual failing rows, and tracing the nulls back to the model or source. Use when dbt test reports a Database Error on a not_null test. Not for test configuration errors, which fail at parse time instead.
Fixes a snapshot broken after an agent reordered models in the DAG, moving the snapshot before an upstream model it depends on. Use when a snapshot runs against stale or missing upstream data after a DAG change. Not for snapshots whose upstream is a raw source.
