The Crucible — a public replication ledger for scientific and technical claims

A public, machine-readable ledger of 53 scientific and technical claims rebuilt as minimal computational models and tested in code: 21 reproduced, 12 failed, 20 not computable (an honest pass, where a claim has no simulable core). Every verdict ships a runnable model and a measured number. FAILED verdicts are published as prominently as REPRODUCED ones: a replication record with no failures is a record that only tested safe claims. Verdicts are produced by rebuilding the stated mechanism as the smallest model that expresses it, not by re-running the original authors' code or data, so REPRODUCED means the mechanism holds in that minimal model rather than that the original study replicates in its own setting. Counts in this description are read from the deposited ledger and cross-checked against a recount of its entries. Live ledger: https://dancenitra.github.io/agora/public/crucible/
