+**For Vercel migrations:**

+- **Derives what it can't export** — Vercel's infrastructure (CloudFront-equivalent behaviors, function tuning, edge routing) isn't directly readable, so discovery works from your build output, source configs (`next.config.js`, `middleware.ts`, `vercel.json`), and the Vercel API instead
+- **Computes a Coupling Score** — ISR, edge middleware, edge runtime routes, image optimization, streaming SSR, preview deployments, and Vercel-managed stores (KV/Postgres/Blob/Edge Config/Cron), each with a detection method and why it matters
+- **Runs 10 named Pre-Flight Checks** — including a flagship check for cached routes that intersect with middleware (a behavior change on every AWS target, not just one), computed unconditionally and filtered to whatever outcome fits you
+- **Recommends one of three honest outcomes** — OpenNext/SST (serverless), ECS Fargate (containerized), or a Vercel+AWS Hybrid (your backend moves, your Next.js app and PR previews stay on Vercel) — via a fixed, auditable decision order, never a guess
+- **Tells you what you'd lose** — PR preview deployments first, always — and says plainly when this tooling isn't a fit for you (a low-traffic app with no AWS credits is often better served by a VPS)
+- **Estimates costs with Vercel comparison** — three-tier AWS projection (Premium/Balanced/Optimized) compared against your current Vercel spend, using cached AWS pricing data with live MCP fallback
+- **Generates production-ready Terraform** — `baseline.tf` (GuardDuty, CloudTrail, IMDSv2, budget alerts), VPC, compute (Fargate/Lambda/SST per outcome), peripherals (RDS, ElastiCache, S3, EventBridge), and numbered migration scripts with dry-run defaults
