Summary

I ran uvx ty check . on the root dir, one above src.
Cli version: ty 0.0.15 (eb43dff 2026-02-04)

Playground link:

any typeddict with total=False using the generic type syntax [T] triggers the error for expecing True of False, but it found Unknown. As seen in the same line of text, there is a Literal[False]
Using from typing import Generic, Typevar over [T] passes all checks without issue.

Sidenote:
This only happens on the cli. I don't get the same error on vscode, of version 2026.10.0. as mentioned on the extension page: The extension ships with ty==0.0.15.
