Module check 

check: validate the app, its models and its configuration without starting a server or opening a database.

check returns every CheckIssue it finds. The checks, by id prefix:

Prefix	Checks
config	a default database exists when models are managed; database URLs parse and name a known scheme
models	duplicate tables, models and columns; a primary key; foreign-key and many-to-many targets are registered models
migrations	migration files load; the dependency graph is sound; model changes not yet in a migration
openapi	the OpenAPI document generates (duplicate operations and ids)
backend	the models fit the capabilities of the default database’s backend

Issue messages never contain database URLs.

check_build

Check that app can be turned into a router, which catches duplicate routes and malformed path templates that the OpenAPI check does not see (for example hidden endpoints). Consumes the app: call it on a fresh one.
