    Schema & Contract Evolution Toolkit

    Evolve schemas and contracts without breaking clients, fixtures, imports, validation, money, time, or API behavior. This bundle covers enum evolution, GraphQL nullability, form validation, fixture/schema synchronization, pagination contracts, CSV imports, time-zone semantics, and money amounts. Use it when repository layers have changed at different speeds and old assumptions survive in clients, tests, data, docs, generated types, or integration boundaries.

    I have a TypeScript monorepo with a Node API, Prisma/PostgreSQL, generated OpenAPI clients, React, and background jobs. We added PARTIALLY_REFUNDED to the OrderStatus enum. Prisma and the API schema know about it, but one generated client is stale, two frontend switches throw on unknown values, analytics maps unknown statuses to FAILED, an old worker fixture still assumes four values, and the migration note says older app versions may remain during rollout. Repair the enum evolution contract across the repository. Add deterministic local tests for mixed versions and unknown values. Do not query production, change existing order rows, deploy, or decide what PARTIALLY_REFUNDED should mean to the business.

    Your agent does

    Enum evolution drift found. The repository has a stale generated client, two closed-world UI switches, unsafe analytics coercion, and incomplete mixed-version coverage. The repair regenerates the client, adds explicit unknown-value handling, preserves existing serialized values, updates fixtures, and adds compatibility tests. Business meaning and deployed compatibility remain human-owned and unverified.
