# Accuracy and evidence

Proves the data is right, not just valid: rebuilt figures, whole populations, stable identities and past results that still reproduce.

- [Can we independently prove these numbers?](https://atlasscope.dev/prompts/can-we-independently-prove-these-numbers): Important figures may be wrong even though their lineage is documented.
- [Find data that is internally consistent but wrong](https://atlasscope.dev/prompts/find-data-that-is-internally-consistent-but-wrong): Every check passes, but totals or outputs still look implausible.
- [Find where records silently change identity](https://atlasscope.dev/prompts/find-where-records-silently-change-identity): Sources use aliases, changing identifiers, share classes or inconsistent names for the same thing.
- [Reproduce what the database believed in the past](https://atlasscope.dev/prompts/reproduce-what-the-database-believed-in-the-past): Past reports, backfills, restatements or changed classification rules matter.
