Anchor grammar: recital-style ordinal dates and worded percentages
First pass of the measure->fix->re-measure loop on held-out gold:
CUAD typed-containment recall (13,823 expert spans, 510 contracts,
zero LAB overlap) scored 39.0% overall with dates at 50.6%; the
dominant measured gap was recital drafting ("the 15th day of March,
2027", "March 15th, 2027") plus worded percentages ("fifty percent").
After the two grammar productions: dates 69.8% (+19.2pp), Agreement
Date 53.4%->76.3%, overall 43.9%. Duration categories were already
strong (Notice Period 82.0%, Renewal Term 73.8%). The money-category
ceiling is largely structural - many CUAD cap/commitment spans
contain prose with no extractable literal - and is left for the
corpus sweep rather than pattern-chasing.
