The route regroups flat props into lines[] and was dropping the role tag, so the widened feed reached the browser untagged. That is not cosmetic: on a live prop, PrizePicks prices both sides at even money (+100/+100) while BetMGM has +450/-750. Rendered side by side without a tag, the pick'em row reads as a dramatically better price when it is a different product entirely -- exactly the confusion the three-way split exists to prevent. Consumers gate on book_role !== 'dfs' before treating a row as a market price. The ?book= filter now accepts any DISPLAY book, since shopping a real book against an exchange is the point of the widening. Grading still only ever consumes MODEL_BOOKS. One superseded integration test updated to a stronger pair: an unknown book still 400s, and a newly-visible one no longer does. Gates: 4,028 tests / 322 suites green; next build exit 0.
