Jagged Edges
Where Jev breaks, and how to build around it
The failure modes that bite in production: numeric blindness, date comparison, context rot, adversarial state, and the structural invariants that simply do not hold.
What you’ll be able to do
- ✓Recognize which half of a problem belongs in code, not the model
- ✓Extract dates as enumerated Choices and compare them yourself
- ✓Stop assuming Noul and Choice probabilities are interchangeable
- ✓Test adversarial state before it reaches real users

Dates, Times, and Ordered Quantities
paidJev reads dates as text. Rebuild a date comparison as extraction plus code.

Context Rot and Large State
paidAccuracy falls as irrelevant detail grows. Filter first — including with Jev itself.

The Invariants That Don't Hold
paidNoul 0.72 plus its negation at 0.47 sums to 1.19. Why that is fine, and what it means for your thresholds.

Adversarial State
paidState is data, and Jev does not treat it as hostile. Build a test suite that tries to move the answer.
