# Offline regression for scripts/phase-02-vault-preflight.sh. Drives the REAL
# script's decision/exit logic with juju+jq shims (fakebin/) against generated
# fixtures: one healthy (PROCEED / exit 0) and four single-fault cases the live
# healthy system cannot show -- vault-already-initialized (D), mysql OFFLINE (C),
# a hook failure (E), a down machine (B) -- each must HOLD / exit 1.
#
# Touches NO live infrastructure: fake 'juju' emits fixtures only; fake 'jq'
# mirrors the script's metrics logic in Python. fakebin/ is first on PATH so the
# real juju/jq are shadowed. Runs anywhere with python3 + bash (no real jq needed).
#
# Usage:  bash tests/phase-02/run-tests.sh
# Exit:   0 all cases pass | 1 any mismatch
# ASCII + LF.
