Journey Deploy

Hits your live URL with curl, invokes every HTTP function you built, walks you through an OAuth round-trip if configured, and checks function logs for errors. Writes a timestamped pass/fail line to the build log for each check and blocks progression to journey-submit if anything's broken. The anti-patterns section is spot on: a 200 from your landing page means nothing if your functions throw 500s, and judges will absolutely try to log in if you claim auth works. Solid guardrail against demo day disasters.
