Here's the reality: the pause moved the certification date, not your obligations. You're still affirming NIST 800-171 compliance every time you post an SPRS score, and that's exactly what the False Claims Act cases are built on. Most companies need 6–12 months to close real gaps, and when DoD sets a new date, everyone will be scrambling for the same assessors. The contractors who keep going now will be ready.
