## Description

Prepares production launches. Use when preparing to deploy to production, or when asking what needs to be in place before shipping. Use when you need a pre-launch checklist, when setting up monitoring, when planning a staged rollout, or when you need a rollback strategy.

# Shipping and Launch

## Overview

Ship with confidence. The goal is not just to deploy, it's to deploy safely, with monitoring in place, a rollback plan ready, and a clear understanding of what success looks like. Every launch should be reversible, observable, and incremental.

## When to Use

- Deploying a feature to production for the first time
- Releasing a significant change to users
- Migrating data or infrastructure
- Opening a beta or early access program
- Any deployment that carries risk (all of them)

## The Pre-Launch Checklist

### Code Quality

- [ ] All tests pass (unit, integration, e2e)
- [ ] Build succeeds with no warnings
- [ ] Lint and type checking pass
- [ ] Code reviewed and approved
- [ ] No TODO comments that should be resolved before launch
- [ ] No `console.log` debugging statements in production code
- [ ] Error handling covers expected failure modes

### Security

- [ ] No secrets in code or version control
- [ ] The ecosystem's dependency audit (`npm audit`, `pip-audit`, `cargo audit`, ...) shows no critical or high vulnerabilities
- [ ] Input validation on all user-facing endpoints
- [ ] Authentication and authorization checks in place
- [ ] Security headers configured (CSP, HSTS, etc.)
- [ ] Rate limiting on authentication endpoints
- [ ] CORS configured to specific origins (not wildcard)

### Performance

- [ ] Core Web Vitals within "Good" thresholds
- [ ] No N+1 queries in critical paths
- [ ] Images optimized (compression, responsive sizes, lazy loading)
- [ ] Bundle size within budget
- [ ] Database queries have appropriate indexes
- [ ] Caching configured for static assets and repeated queries
