# Synthetic post-deploy journey.
#
# `post-publish-verify.yml` proves the published image boots. This one
# proves that on a running instance a person can sign in, write a reading
# and read it back, and that the instance serves the version that was just
# published.
#
# Deliberately manual for now: the maintainer picks the target instance and
# creates the two repository secrets. Nothing calls this from the deploy
# path yet.
#
# Secrets, both required:
#   SYNTHETIC_USERNAME — the probe account's username or email
#   SYNTHETIC_PASSWORD — its password
#
# The probe account must be password-only (the password flow stops at the
# MFA ticket, which the script reports as a configuration failure), and the
# target must not be the demo instance, where every mutation is blocked.

      # own const allowlist and exits 2 on anything else, so a dispatch that
      # goes round this form still cannot reach a stranger's collector.
