GhostPaw Codex runs on your own machine — the client starts it, so there is no endpoint to ping. 7 installs a week from npm. Last commit 24 Oct 2026.
Local belief and memory engine with evidence, certainty, and honest revision history.
Today is the operative word: we check GhostPaw Codex every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
