Recognises a deletion not reaching the copies
The record deletes; copies keep the data and no flow carries deletions.
Can AI do this?
AI does this well Most of the tested AI models master this. 3 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 98% | Mastered |
| gemini-3.5-flash-lite | Low cost | 6% | Not shown |
| gpt-6-luna | Low cost | 98% | Mastered |
| claude-haiku-5-5 | Low cost | 98% | 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 entity and the flow to carry deletions
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: EN-008 Card: card management D; warehouse R; no flow carries deletes Acceptable: The warehouse flow carries deletions or tombstones
Also known as: Deletion that does not propagate
