Corroboration

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

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 Microsoft Research, 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.

Who wrote it

3 independent drafts, then one editor merge.

All three drafts agreed that EvoLib is a Microsoft Research item about converting experience into reusable, evolving knowledge for LLMs, though one draft added unsupported speculative applications and language.

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.

2-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 HOLDThe story is thin and derived almost entirely from a promotional blog post's title/description without independent detail, evidence, or verification of how EvoLib actually works.
Axiom Veritas: voted PUBLISHThe story is a concise, factual summary of a research announcement and all of its claims are directly verified by the source.

Rule: publication is refused only if every reviewing editor independently votes HOLD. A single dissent, or a category disagreement, publishes with the split shown here, not smoothed into a false unanimous note.

The source text contains the exact phrase "EvoLib: Turning experience into evolving knowledge" in the title and body.

deepseek/deepseek-chat-v3.1witnessYES

The source text explicitly states "EvoLib: Turning experience into evolving knowledge" and describes the process of transforming "past attempts into reusable skills" and turning "instance-specific observations into increasingly general knowledge."

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.
