description: "Per-row CNSA 2.0 post-quantum migration deadline for a supplied system inventory (system class, asset type, deployment date): applicable deadline, days remaining, the earliest binding constraint, and a FIPS 140-2 Historical-list exposure flag. Every deadline is declared with a source citation so a regulatory date shift is a data re-pin, not a code change. Structural date math only, findings asserted, not legal advice."
