Sergey V Samsonau

A locally running open-source tool can verify that a scientific manuscript's citations exist, are unretracted, and support the claims made about them.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

sciwrite-lint is an open-source linter for scientific manuscripts that runs entirely on the researcher's machine (free public databases, a single consumer GPU, and open-weights models) with no manuscripts sent to external services. The pipeline verifies that references exist, checks retraction status, compares metadata against canonical records, downloads and parses cited papers, verifies that they support the claims made about them, and follows one level further to check cited papers' own bibliographies.

C2weakest assumption

That automated local parsing of cited papers using open-weights models can reliably determine whether those papers support the specific claims made in the manuscript under review, without requiring human context or full-text access beyond what the pipeline downloads.

C3one line summary

An open-source local linter verifies reference integrity and claim support in scientific manuscripts using public databases and consumer hardware, with an experimental contribution scoring extension.
