  "note": "**This threshold is not a tuned parameter, and the shipped policy default stays at 0.84.** Three runs against this corpus, two seed replicates and this retrain, read 0.69, 0.83 and 0.81, and the validation curve is flat across the whole range that matters: macro F1 moves from 0.9288 at 0.50 to a peak of 0.9372 at 0.81, a spread of 0.0084 over 45 points of threshold. 0.84 reads 0.9369 on the same curve, indistinguishable from the calibrated value. 0.84 is the reviewed value shipped before this retrain and is unchanged by it."
