description: "Rule 605 publication composer over caller-declared best-ex/669-shaped inputs: the effective-vs-quoted spread ratio (eq_ratio, 2dp half-up), the covered-order roll-up echoes (declared orders_covered and shares_covered), and a publication-row builder for declared categories. Declared-input discipline: covered orders, covered shares, and spread statistics are your declarations, never observations this kernel makes; no market data, tape, venue, or order-management system is read. PUBLICATION_ROWS_BUILT is a composition verdict, not an obligation assessment. Absent or invalid inputs fail closed and are named. No network, no storage, no clock."
