DeltAgent made up reasons when it had no evidence

status: done confidence: high published

DeltAgent explains why a number in the management accounts moved. Some lines have no evidence anywhere: no message, no email, no meeting. The right output for those is “I can’t find a reason”. The agent wrote a plausible reason anyway.

The eval measures this as unsupported precision. 1.00 means the agent held back on every line it had no evidence for. 0.00 means it made something up.

Round 3 fixes didn’t touch it. Round 4 did.

What I took from it: the model will fill a gap unless you test for the gap directly. The average score didn’t show the problem. Round 3 scored 75 while 7 of 10 companies still had made-up reasons.
