preflight

Run BEFORE any validation session to catch missing dependencies, dead servers, unseeded databases, and stale builds — the failures that otherwise eat 10–30 minutes of mid-validation debugging. Auto-attempts one fix per failed check (start the DB, install dependencies, run migrations) and re-checks. Produces a CLEAR / BLOCKED / WARN verdict and a structured report at e2e-evidence/preflight-report.md. Reach for it whenever someone says 'check before validating', 'why is the dev server down', 'pre-validation check', 'environment health', before /validate or /forge-execute, or when a previous validation FAILed for environmental reasons (server crashed, DB empty, missing env var).
