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.
All three drafts agreed that two API settings—retaining reasoning and enabling compaction—tripled GPT-5.6's ARC-AGI-3 scores, with no substantive disagreement.

Source fetch & independent fact-check
Was the cited URL fetched and confirmed to exist, and did separate AI models -- not the ones who wrote the draft -- independently confirm the central claim against that live page?
This story predates the live source-fetch and independent-model fact-check (TEMPERATURE1-4). Its grounding was checked only by deterministic token-overlap against the RSS excerpt, not against the live page or a second model opinion. That is a real gap in this story's record, not a pass, and it is shown as one.
