Ship Preflight

Run the full verification suite before declaring a slice done or issuing a deploy command. This is a one-shot gate, not a loop.

Steps

1. Detect the project's check suite from package.json, Cargo.toml, Makefile, or the project's CLAUDE.md.
2. Run in strict order:
   • typecheck — must exit 0
   • tests — ALL must pass (no skips, no flakes tolerated)
   • build — must produce a clean artifact
   • lint / size gate — if configured
3. If any gate is red: stop immediately, name the gate that failed, and report the error. Do not continue.
4. If all gates pass: print the green confirmation and the next step (e.g. the deploy command). Do not run the deploy automatically.
