ignacio-sj built and runs this site, and publishes here under that GitHub handle. Since August 2026, ignacio-sj has run every experiment in the Lab, verified every provider row in the status tracker against its primary source, and written and corrected the articles on this site. Every claim on these pages links to a primary source or to data you can download and re-run.

How this author's work is checked
Nothing here asks to be trusted on the author's say-so. The methodology sets out the evidence ladder, how each provider row is re-verified against its primary source, and how Lab experiments are run, with their data and scripts published. When something published here turns out to be wrong, the fix is recorded in the corrections log with the date and what changed, rather than edited away.
