// Codegen contract validation check (ARCHITECTURE.md §10 P1-8 / §5.3)
//
// Runs graphql-codegen and fails if any output with skipDocumentsValidation:false
// contains operations that reference non-existent schema fields.
// This is the "codegen diff check" — it diffs operations against schema.
//
// Currently enforces:
// - dashboard-types.ts output (skipDocumentsValidation: false, P1-7)
// As more domains fix their operations, their outputs will be validated too.
//
// Usage: tsx scripts/check-codegen.ts
// Exit: 0 = codegen success, 1 = validation errors
//
// Related: ARCHITECTURE.md §5.3 契约纪律, §10 P1-8
