They run before the model because they are two orders of magnitude
faster and score better on both halves of the route. They decline
rather than clarify, so a declined turn carries on to the model and
then the classifier, which is what a box with no weights file does on
every turn. Nil heads are byte-for-byte the cascade that shipped
before this.
Measured on the 96-case fixture, classifier+ONNX either way:
intent 76.0% -> 96.9%
destination 36.4% -> 75.8%
false clarify 0 -> 1
missed clarify 8 -> 1
p50 24.5ms -> 27.9ms
That beats the gemma-4-12b cascade on both halves, 84.4% and 72.7%, at
a twelfth of its 329ms. The four remaining destination misses are all
calendar, which is the stage 0 trade V-660 flagged and the owner has
not called yet.
