BookComparison.tsx was built but UNROUTED (dead). Route it to the GradeResultCard via a new self-fetching BookComparisonPanel that reads the live /api/books feed (source:'bookprices' — the snapshot-locked, fenced, byte-identical store). Contract fix (Review Zero 0.1): books frequently sit at DIFFERENT lines (WNBA DK 21.5 / FD 18.5; MLB 2/3), so BookComparison now renders EACH book's own line per-row — never one shared header line implying a false same-number comparison. Honest states: single-book (the common case for MLB) → one book, "One book posting this prop.", NO crown/second row; multi-book → all books' own line+price, NONE crowned (BOOK_CROWN_ENABLED=false — no best-price claim, verified live crowned:false); no books → renders NULL (panel self-hides), never a placeholder. No regression: only the always-empty inline d.books section was replaced; grade, projection, PropLine line, and PriceTriplet price are untouched (wiring test asserts them). Freshness (0.4): bookprices is written in the SAME snapshot that locks the grade (intraday refresh touches neither gradedAt.line nor bookprices) — same fresh, no stale-label needed. Web-only → grade byte-identical trivially. Full suite 3851 green, web build exit 0.
