#  Phase 7.2/7.3 scripted evaluation: end-to-end agent scenarios in fresh
#  scratch workspaces under /tmp, plus live safety tests. Each scenario
#  seeds its workspace, runs the headless CLI, then asserts artifacts, the
#  final answer, policy-gate behavior for the mode used, audit completeness,
#  and transcript coherence (via scripts/eval-inspect.py).
#
#  Usage: scripts/agent-eval.sh <id ...> | scenarios | safety | all | clean
#    scenarios: s1 s2 s3 s4 s5 s6 s7 s8 s9 s1x s3x
#    safety:    sf1m sf1g sf1a sf1x sf2 sf3 sf4 sf5

#  $EVAL_ROOT (default /tmp/zyquo-eval). API keys are sourced from
#  .secrets/api-keys.env and are never printed.
