Checktrail runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 21 Sep 2026.
Local code validation with explicit execution trust and evidence of what actually ran.
Nothing serious here today
Today is the operative word: we check Checktrail every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
