# Phase 15 fail-closed gate (Journal plugin + proof host). Every stage exits
# non-zero on a failing command, a go test run that fails, skips, matches
# zero tests, prints "no tests to run", a named required test that did not
# pass, a data race, a dirty PHP pin tree, a forbidden surface, or an
# unmitigated high threat. --self-test proves the detector fails closed on
# planted inputs. --all runs every stage and must end with
# "Phase 15 gate passed".
#
# Sibling repositories are invoked with `go -C`. Full mode runs Postgres
# integration and treats Docker unavailability as failure; -short is not
# final evidence.
