Mark CXXXVI
The Launch Gate
Shipped April 26, 2026
What it is
Founder-only pre-flight checklist at /vault/launch-gate. Reads the live /api/health probe + augments with founder-side action rows that can't be probed (Stripe products, FOUNDING30 coupon, Anthropic prepay, ElevenLabs prepay). Every blocking row shows an EXACT fix recipe (env var name, Stripe field values, top-up amount + URL). Driven by 2026-04-26 prod smoke-test which showed overall:degraded — Stripe + Redis + Resend env vars unset in Vercel. Without those: no real checkout, no rate-limiting, no transactional/lifecycle/Oracle email. Code is ready and waiting; this Mark makes the gap impossible to miss. Tone-coded rows (emerald=ok, amber=blocking, royal=todo) with concrete external links to each provider's setup page. Vault sub-nav extended with amber-accent Launch Gate pill.
