Recognises a check with no rule behind it
A DQ rule with no source_rules and no source_requirements. It enforces a threshold nobody agreed to, and the first argument about it happens when it rejects production data.
Can AI do this?
AI does this well Most of the tested AI models master this. 8 of 10 models master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 99% | Mastered |
| gemini-3.1-pro-preview | Flagship | 98% | Mastered |
| gpt-6-astra | Flagship | 99% | Mastered |
| claude-fable-5-1 | Flagship | 100% | Mastered |
| gemini-3.8-flash | Mid tier | 99% | Mastered |
| gpt-6.1-sol | Mid tier | 99% | Mastered |
| claude-sonnet-5-5 | Mid tier | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 50% | Not shown |
| gpt-6-luna | Low cost | 65% | Not shown |
| claude-haiku-5-5 | Low cost | 99% | Mastered |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: The check and the rule or requirement it needs, or its retirement
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: DQ-030: account identifier is 20 characters, no source; the feed also carries non-Estonian IBANs Acceptable: A data rule for the IBAN format, scoped to Estonian IBANs, cited by the check; or the check removed (DQR-006)
Also known as: Check with no rule behind it (data quality rule)
