Add one field to a data type and let it land in the API, the store, and the client types. Count the files you touch by hand — generated ones don't count.
18 is ours, counted on 1 Sep 2026: one scalar field on one data type lives in 18 hand-written files across our two repos — schema, DTOs, history strategy, client type, Zod schemas, two separate forms, list, detail, error label, mocks, specs. We repeated the count on two more fields and got 18 again, and 20.
