V-565. internal/claim holds Claim{Claimant, Intent, Filled, Consumed,
Unexplained, Band, Veto} and imports nothing from Maven, so the dialogue to
router edge stays impossible. internal/router/claim.go builds one from a
Decision. Additive: nothing in Route calls it and Decision.Confidence is
untouched.
Measured first, on the 91-case fixture. Stage 0 emits 1.0 always and is right
20/20. The classifier cosine spans 0.859 to 0.942 and is right 62% of the
time, with 62% correct below its median and 62% above, so the number carries
no signal about correctness. The top1 to top2 margin is worse: p50 0.009, 68
of 71 cases under 0.02. A calibrated float is not cheaply available from the
classifier, which is what the task's ledger asked to be checked.
So four ordinal bands, highest first: anchored, structural, nearest, vetoed,
with unknown at the bottom so a builder that forgot cannot outrank a measured
claim. Anchored against nearest is 100% against 62% on the same utterances.
Nearest is one band and not a scale because the cosine is flat.
Coverage decides before the band does. That is what fixes Rome: the pending
claimant ate the question while explaining one token of it.
No fixture number moved. TestONNXBaseline is 64/91.
