"summary": "The 13 July 2026 suspension removed the third-party assessment mechanism and left safeguarding obligations and flow-down duties intact. Primes have reverted to the questionnaires CMMC existed to replace.",
"lede": "Primes built supplier assurance plans around certification dates that no longer apply. The obligation to protect controlled information did not pause, which leaves a gap that has to be filled with something — and the default is the thing that did not work.",

"Requirements language should be scenario-neutral, because the suspension's duration is unknown and nobody should forecast it."

"a": "Nobody knows, and this article deliberately does not forecast it. The requirements language is written to be scenario-neutral for that reason."

"q": "Can we require more than the contract flows down?",
"a": "Primes routinely impose requirements beyond the minimum flow-down through their own terms. Whether to do so is a commercial decision informed by counsel."
},
{
"q": "What about suppliers who refuse?",
"a": "Tier the requirement by what they actually hold. A supplier who never receives covered defense information should not be asked for records about protecting it."
},
{
"q": "Is this wasted if certification resumes?",
"a": "No. The artefacts are what a certified supplier produces anyway, and they cover the period between assessments, which is most of the time."
},
{
"q": "Does a programme pause remove the obligation?",
"a": "No. Safeguarding clauses sit in the contract and the annual affirmation continues. Sequencing changed, not the requirement."

{
"q": "What is realistic to ask a supplier for?",
"a": "A correlation identifier, receipts for a bounded access class, contractual retention, and verification that does not require contacting them."

{
"q": "How should suppliers be ranked?",
"a": "By what they can reach, not by spend. Data access is the exposure."
