What the projects try to preserve
Source traceability
Material claims should lead back to identifiable sources rather than anonymous summaries.
History before snapshots
Current state matters, but so do migrations, closures, incidents, rebrands, restrictions, and unresolved transitions.
Explicit uncertainty
Unknown, incomplete, disputed, and not-yet-reviewed information should remain visible instead of being silently filled in.
No implied recommendation
Registries and dashboards describe recorded conditions. They are not investment, safety, or legal recommendations.
About the lab
An independent, small-scale publishing and software project.
BadJoke-Lab is maintained independently. Repositories, issue trackers, and public methodology pages are used to document implementation and correction work. Project-specific coverage and limitations are described on each site.
