Credence — Epistemic Guard runs on your own machine — the client starts it, so there is no endpoint to ping. 116 installs a week from pypi. Last commit 16 Jul 2026.
Epistemic guard for AI coding: tracks uncertain values and blocks writes until verified.
Today is the operative word: we check Credence — Epistemic Guard every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
