Install the AET CLI, then copy or install the five Skill directories supported
by your Codex environment. Invoke only the Skill that answers the current
question: /aet-check, /aet-scope, /aet-proof, /aet-fresh, or
/aet-plan.
/aet-proof is the only daily Quick Skill that executes the explicit argv
after --. /aet-plan is read-only and stops at PROPOSED.
Codex may interpret the resulting JSON, but must not promote UNKNOWN,
Observed facts, or a proposed Plan into verified Evidence or release authority.
