- printing-press verify: builds CLI, tests every command against real API or mock
- Two paths: --api-key for live testing (read-only GETs), mock server fallback
- Discovers commands from root.go, classifies as READ/WRITE/LOCAL
- Tests: help, dry-run, execute per command + data pipeline (sync->sql->search)
- Scores pass/fail with PASS/WARN/FAIL verdict
- fixloop.go: auto-patches common failures (max 3 iterations)
- config.go.tmpl: adds <API>_BASE_URL env var override for all generated CLIs
