Never let a deduplication delete run unpreviewed: compute the exact rows the rule would remove, check them against the rule's assumptions, such as which duplicate is kept, and require the removal count to match an expected duplicate count before executing. Use when an agent cleaning duplicate rows from a production ta…

Do not just rerun the suite: query the table for the null rows the expectation flagged, decide whether the nulls are a source bug or a rule that is too strict for a legitimately optional column, fix at that layer, and rerun only the failed expectation. Use when a Great Expectations suite guarding a production table. N…
Fixes a health score recompute that crashes on null usage values by defining explicit null semantics per component. Use when scoring runs die on accounts with missing usage. Not for nulls caused by a total pipeline outage.
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.
Handles a triage run failing when the mailbox search API returns empty results mid-campaign, by distinguishing a true empty result from a failed or malformed query. Use when search-based sweeps intermittently return zero results for mail known to exist. Not for mailboxes that genuinely contain no matching mail.
