ScoreLegacy runs the actual router cascade against the 136-example
corpus and produces per-route precision/recall/F1, confusion matrix,
false-action breakdown, and fast-path/residual/router-residual/pre-route
consumption counts. Pre-route consumed cases (command-prohibition grammar
matches at stage 0) are tracked separately — these never reach the
general cascade and should not be scored by the learned router.
ContrastFamilies splits the baseline report by transform tag (negation,
question, reported_speech, quotation, hypothetical, capability_question)
and reports per-family accuracy and false-action rate.
LegacyReport.String() renders the full baseline report with confusion
matrix and false-action case listing.
