Pith is building a public, inspectable history of what a paper claimed, what was checked, what was challenged, and what was later corrected or superseded. It will not add the record up into a score.
Pith will not tell you whether a paper is true. It shows the record and its limits so you can judge the evidence.
Every source stays separate. Silence is never turned into a clean bill of health.
Pith is an open preprint site with review built in, alongside arXiv rather than on top of it.
Enter an arXiv ID. Pith resolves the paper and queries each live source separately.

Investigation of the circulation history of the essays, which demonstrates that multiple-format republication was standard practice in early 20th-century scientific publishing.
Contemporary documents from the 1940s criticizing Planck's republications as improper or revealing scientific flaws in the essays would undermine the claim that the retractions are purely anachronisti

Publication freezes a citable version, not the world around it.
Sources move. Errors are found. Claims are challenged. Analyses are rerun. Papers are revised or superseded. When those events are scattered across databases and private correspondence, readers cannot reconstruct what changed or why.
Pith’s answer is a dated record whose sources, limits, and disagreements remain visible, without collapsing them into one score.
The record keeps kinds of evidence separate because they answer different questions.
Evidence type
What a named source contained at a stated time.
Evidence type
A named program produced a repeatable result from fixed inputs.
Evidence type
A model produced an assessment. It remains a fallible judgment.
Evidence type
An attributed person made a review, objection, or challenge.
Evidence type
A small formal proof checker accepted an exact machine statement under listed assumptions. Whether the statement represents the scientific prose or the world remains challengeable.
History rule
Challenges, corrections, and superseding records point to their target without deleting what came before.
Every view must name the paper identity, collected records, observation time, and rules used to produce it. A generated paper history is a dated reconstruction from declared inputs. It is never stored as canonical truth.
Pith can query integrity findings from named detectors; extracted claim text and dependency edges; stored citations, with quoted context available on citation surfaces; and neutral one-hop flags about external events involving cited works.
Each source keeps its own coverage and limits. They are not merged into a paper verdict or a single timeline.
Pith is building typed, content-addressed records around those sources. Content-addressed means the identifier changes when the record’s bytes change.
The generated paper biography and replay by separately controlled operators remain shadow until their preregistered tests pass.
Scientists
Inspect exact records around a paper, distinguish silence from missing coverage, and challenge a specific judgment.
Readers
Follow what changed without relying on a score or treating Pith as a truth authority.
Funders
See what is live, what remains contingent, and which published tests can stop the next phase.

Disagree with a finding or extracted claim? Challenge that item and cite the evidence.
The original record and the challenge remain public. Disagreement does not silently rewrite history.

/mesh.json and /evidence.json expose the public dossier schema used by this page. Responses include the schema version, observation time, source states, and a context_digest, a hash clients can use to detect a changed rendering context.
Separately timed requests are not promised to be identical. Compare digests before treating two responses as the same observation. Preserve evidence types; never promote a capture or delivery notice into an accepted check.
