Data pipelines rarely fail only when a job crashes. More often, a feed keeps running while fields quietly disappear, rows shift, or a source corrects a historical record.
A useful review workflow is deliberately small:
- capture a defined before/after snapshot,
- compare row and field changes against stable keys,
- retain evidence sufficient for a human to inspect the change,
- make the downstream response an explicit review decision rather than an automatic claim of correctness.
That separation matters. A detected difference is an observation—not proof that a source is wrong, a policy should change, or an operational action is safe to take.
For teams that want to try that workflow, Dataset Diff Engine v2 compares supported Apify datasets or snapshots and returns structured change records for review. It is an inspection aid, not a data-quality certification, source-of-truth replacement, or automated remediation system.

If the input problem begins earlier—messy CSV or JSON records—a separate CSV/JSON Schema Normalizer v2 can help derive a reviewable schema and normalization output. It does not prove semantic correctness or production readiness.

The practical rule is simple: preserve the observed change, make the decision criteria visible, and keep a human responsible for the consequential step.
