CNSA 2.0 Deadline Ladder Calculator

For a supplied inventory of systems (system class, asset type, deployment date), computes the applicable CNSA 2.0 migration deadline, days remaining, the earliest binding constraint, and a FIPS 140-2 Historical-list exposure flag. Every deadline is declared below with a source citation, so a regulatory date shift is a data re-pin, never a code change.

⚠ NOT a security scanner, NOT a cryptographic audit, NOT legal advice. Structural date math over your own supplied inventory only. Findings are asserted — verify current NSA CNSA 2.0 and NIST FIPS 140-2 guidance against official sources before acting.
