AI governance instruments consistently fail to reconstitute on promised timelines after rescission, with substitute instruments governing different pipeline stages

Three independent governance instruments in AI-adjacent domains were rescinded with promised replacements that failed to materialize on stated timelines: (1) EO 14292 rescinded DURC/PEPP institutional review with 120-day replacement deadline, now 7+ months overdue with nucleic acid synthesis screening substituted (different pipeline stage); (2) Biden AI Diffusion Framework rescinded May 2025 with 4-6 week replacement promise, now 9+ months overdue with three interim guidance documents instead of comprehensive framework; (3) DOD Supply Chain Designation of Anthropic deployed March 2026, reversed 6 weeks later through political negotiation with no legal precedent established. The pattern shows: governance instrument → rescission → replacement promised → replacement not delivered → gap filled by weaker substitute addressing different mechanism. The supply chain case reversed fastest (6 weeks) because AI capability was most strategically indispensable, suggesting governance gap duration inversely correlates with strategic indispensability. In two cases, replacement instruments addressed different pipeline stages (DURC institutional review → synthesis screening; comprehensive diffusion framework → chip-threshold restrictions), creating false assurance of continued governance while actual control points shifted. This represents a structural pattern where AI governance cannot maintain continuity when capability advances outpace governance cycles.

Supporting Evidence

Political resolution of Mythos case through White House negotiation (Trump signaling 'deal is possible' April 21) means settlement before May 19 prevents DC Circuit from ruling on constitutional question. This leaves First Amendment question unresolved for all future cases. The 'responsive governance' here means the coercive instrument became untenable and was replaced with bilateral negotiation - not governance strengthening but governance instrument self-negation without reconstitution of alternative binding mechanism.

The pattern holds across three domains: DURC/PEPP biosecurity (7+ months), BIS AI diffusion rule (9+ months), supply chain designation (6 weeks) — the intervention is mandatory continuity requirements in administrative law, not better governance design
