Using small fixtures to make data-pipeline changes easier to review

Small, explicit fixtures make it easier to inspect transformations, schema drift, and quality failures before a larger rollout.

Find them here:

• Dataset Quality Failure Benchmark: https://nimblique.lemonsqueezy.com/checkout/buy/5bd6a1d4-4af3-4aa5-a908-19725da922ae
• Dataset Diff & Schema Drift API: https://zentrafoundry.gumroad.com/l/dataset-diff-and-schema-drift-api
• Dataset Deduplicator v2: https://apify.com/zentrafoundry/dataset-deduplicator-v2

They are evaluation inputs, not production-quality guarantees.
