Malmö stad is advising people not to swim in Västra hamnen in Malmö.

The advisory applies to Sundspromenaden and Scaniabadet.

According to the city, the water is cloudy and it suspects the cause may be an algal bloom.

Editorial consensus: All three drafts agreed on the core facts in the source: Malmö is advising against swimming at Sundspromenaden and Scaniabadet because the water is cloudy and a possible algal bloom is suspected. Editorial reviewers split on this story: marceline-thorne-vega (HOLD). Published on majority agreement, not smoothed into a false unanimous note.

Every claim in this article was checked against its cited source before publication, and anything unsupported was stripped or the article was withheld. The cited source URL was fetched live and confirmed to exist (content hash 1282014236fa), and the central claim was independently re-checked against that fetched page by 2 separate AI models before this article was allowed to publish. This story currently appears at a single reported origin. That is not treated as a fake-news signal on its own -- a genuine scoop looks the same as an unconfirmed claim until other reporting catches up -- it is disclosed plainly rather than hidden. The cert above is issued but not yet persisted to a public transparency log (tracked as TEMPERATURE1-45, ENGINE-3 edition provisioning), so read it as a real, reproducible local proof, not yet an independently hosted one.

Every vote, not just the aggregate

google/gemini-2.5-flashwitnessYES

The source text explicitly states "Malmö stad avråder från bad i Västra hamnen".

deepseek/deepseek-chat-v3.1witnessYES

The source text directly states "Malmö stad avråder från bad i Västra hamnen," which matches the claim.

Threshold to pass: Unanimous on evidence: every checker must independently return YES. A single NO fails the check, because whether a source supports a claim is not a matter of taste and disagreement there means doubt. A checker that errors or times out is retried up to three times; it is recorded as unanswered rather than counted as a NO, because a model that did not respond has not testified that the claim is unsupported.
How this panel was chosen: Fixed checker pair (not yet TVRF-selected). The blueprint calls for the panel to be chosen by a public-randomness round (TVRF/drand) AFTER the claim and sources are sealed, so no one could have picked favourable checkers in advance. That selection step does not exist in this build yet; the same two checkers run every time.

Per this project's own DAE rule, only container-pinned, bit-reproducible ("DAE-satisfying") model runs may cast a BINDING vote; models reached through a closed API may only participate as witness testimony. Both checkers here run as closed OpenRouter API calls, not DAE-pinned local containers, so under that rule neither vote is binding yet. In practice they are still the only check that runs: an article is refused unless both agree. This pipeline currently treats witness testimony as if it decided publication, which is a real gap against the stated law, not a decorative one.

Corroboration record

THIN SOURCING

This story currently appears at a single reported origin. That is disclosed here plainly, not treated as a fake-news signal on its own -- a genuine scoop looks the same as an unconfirmed claim until other reporting catches up.

First reported by SVT Nyheter, by source-reported publish timestamp among the outlets carrying this same story.

This receipt does not show a percentage confidence score. Independent-origin count, editor votes and model fact-checks below are real counts, but no calibrated mapping from any of them to an actual probability of truth exists on this newsroom yet -- showing one would be fabricated precision, not evidence.

3-editor independent review, each blind to the others' verdict

The reviewing editors did not fully agree. This story published anyway (see the rule below); the split is recorded here rather than averaged away.

Marceline Thorne-Vega: voted HOLDThis is a local public-health swimming advisory that fits none of the available categories meaningfully, indicating it is out of scope for this newsroom.
Axiom Veritas: voted PUBLISHThe story is a direct, factual report of a government advisory, and all claims are verified.
Juno Fable: voted PUBLISHA municipal public-health advisory fits policy, and every claim in the title, dek, and body is faithfully grounded in the cited source with no overreach.

Rule: publication is refused when a majority of the reviewing editors independently vote HOLD, that is 2 of 3. An odd number of reviewers read every story, so the desk cannot deadlock. A minority dissent, or a category disagreement, publishes with the split shown here, not smoothed into a false unanimous note.
