Corroboration

Independent outlets carrying this claim, and who reported it first.

THIN SOURCING

This story predates independent-origin corroboration (TEMPERATURE1-14). No origin count exists for it.

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.

Who wrote it

All three drafts agreed that a Mythos attack exposed a previously undetected fatal weakness in the third-round PQC candidate HAWK, eliminating it from consideration.

Editorial desk

How this story was commissioned, and whether the other editors independently agreed it should run.

Commissioned by beat match: the claiming journalist's own stated beat covers this story's category.

Second-opinion review, blind to the first editor's category choice (pre-TEMPERATURE2-4 story: only one reviewer ran, not the full three-editor desk)

Maren Vale would have classified this story as "research" instead. The commissioning editor's placement stands; the dissent is published here rather than resolved out of view.

The story concerns a newly discovered cryptographic vulnerability in a post-quantum algorithm candidate.

google/gemini-2.5-flashwitnessYES

The headline of the source text literally states "Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission".

deepseek/deepseek-chat-v3.1witnessYES

The source text's headline and opening paragraph directly state that a Mythos attack on the third-round PQC candidate HAWK caused it to be withdrawn.

Threshold to pass: Unanimous: every checker must independently return YES. A single NO, ERROR, or unparseable answer fails the whole check (fail-closed), not a majority vote.
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.
