How long does the mandate-regime maturation take to reach architectural-scale enforcement?

A genuinely open question implicit throughout §5.4. The paper documents a clear sequence of historical analogues: SEC Rule 17a-4 preceded the off-channel-communications enforcement wave by more than two decades; HIPAA Security Rule preceded the systematic OCR audit program by approximately a decade; 21 CFR Part 11 was published in 1997 and reached the Applied Therapeutics-style enforcement posture only after FDA inspection capacity caught up with it.

C-0025 places research data at the equivalent point in its own arc: the mandate regime is in place (NIH DMS Policy Jan 2023, Gates/OA.Works Jan 2025, Horizon Europe FAIR mandate, NSF DMP gating, Nelson Memo), the legal theory is settled (Escobar 2016 implied certification), the precedent stack on adjacent fact patterns has accumulated (Duke 2019, Harvard-Anversa 2017, Dana-Farber 2025).

But: the paper does not — and cannot — quantify how long the maturation takes. The historical analogues range from approximately a decade to more than two decades. Research data could fire at the early end (the May 2026 simpler DMSP format and the Gates Foundation programmatic compliance review are already in place), or it could take a full two-decade cycle.

C-0027 (asymmetry binds without timing) makes Q-0043's answer less load-bearing than it would otherwise be. But the question remains open, and its answer determines the time horizon over which §11 R1-R7 should be sequenced.
