At some point in a project’s life, somebody runs a code generator. Maybe they point a client generator at an OpenAPI document, or feed a .proto file to protoc, or write a small script that turns a config file into a lookup table. The output is genuinely useful, so it gets committed, and the project’s interfaces improve overnight. Then, being diligent, the author adds a line to the README: “After changing the schema, re-run make generate and commit the result.”
