Locked decisions

Layer	Decision
Monorepo	pnpm workspaces
Frontend	Next.js (app router), TypeScript required
API	Next.js route handlers (`app/api/`) by default
Database	MongoDB + Mongoose
Validation	Zod (shared schemas in `packages/shared`)
Environments	local → non-prod → prod
Secrets	`.env.local` for dev; AWS for production
Containers	Not required unless deployment target forces it

Project layout

apps/web/                 # Next.js app
  app/api/                # API route handlers
  src/server/             # Server-only code
packages/shared/          # Zod schemas, types, utilities
.github/workflows/        # CI/CD
(root configs)            # eslint, prettier, tsconfig

When to add a separate API service

Only justified if:

Long-running jobs exceed serverless timeouts
WebSocket/persistent connections required
Shared API serves multiple non-Next.js clients
Compliance requires API isolation

Default: keep API in Next.js route handlers.
