dmypy gives errors that mypy does not give, also the error makes no sense

Bug Report

When running dmypy I get this error sometimes:

Linting...
Function is missing a type annotation

>>> 78 class ApplicationDataBaseApplicationModel):

This doesn't make sense for two reasons:

• mypy does not ever error on this line
• There is no function on this line, let alone an unannotated one

The surrounding code looks like this:

class SomeReturnType:
    ...

def my_function(team_id: int, job_id: int) -> type[SomeReturnType]:
    # do some initial work, set some variables etc

    class ApplicationData(BaseApplicationModel):
        # ... more class properties here

To Reproduce

Can't say exactly because dmypy doesn't always give an error.

Expected Behavior

No error.

Your Environment

• Mypy version used: v1.15
• Mypy command-line flags: none
• Mypy configuration options from mypy.ini (and other config files): see my previous issues
• Python version used: 3.11

Beginne damit, das Beispiel mit der verschachtelten Klasse unter Python 3.11 zu reproduzieren und die Ergebnisse von dmypy und mypy zu vergleichen. Das Issue ist erledigt, wenn dmypy keinen fälschlicherweise gemeldeten Fehler wegen fehlender Annotation mehr meldet, wo mypy dies nicht tut, auch über wiederholte Daemon-Läufe hinweg.
