"""Ask the same clinical question several ways; the answer must not change.
|
|
|
|
The 90-case suite pins one exact wording per case, and `rag/understanding.py`
|
|
routes on hardcoded Vietnamese phrase lists (`candidate_cues`, `patient_cues`).
|
|
Together those make it possible to pass eval while a user who phrases the same
|
|
question differently gets a different outcome -- the system would be memorising
|
|
the test, not understanding the request. Nothing in the existing harness can
|
|
detect that, because every case is a single phrasing.
|
|
|
|
This probe closes that hole. Each group below is ONE clinical intent written
|
|
several ways by hand (not model-generated: a model asked to paraphrase tends to
|
|
preserve the distinctive words that drive the routing, which is exactly what
|
|
must vary). A group is CONSISTENT when every phrasing lands on the same
|
|
decision. Which decision is right is a separate question -- this measures
|
|
stability, not correctness, and instability is a defect regardless of which
|
|
answer is the good one.
