The user-visible capability +is: given SaaS support tickets, spend cheap model calls first for routine +priority/owner/next-action triage, climb to a stronger analyst model when the +cheap answer does not resolve, and reserve the frontier incident-commander model +for enterprise incidents, billing risk, compliance-sensitive cases and outages. +The policy is data, not Python: the workload is +`proofs/tasks/support_triage.jsonl`, and the ladder, pricing, budgets and judge +live under `proofs/config/support_triage/`. + +I tested this laptop with: + +```bash +curl -sS http://127.0.0.1:8112/healthz +``` + +It returned `curl: (7) Failed to connect to 127.0.0.1 port 8112`, so the proof +outputs below were captured with `--offline`.
