Pyright flagged both as reportAttributeAccessIssue and behave failed to import the screen module, masking the entire scenario suite under a single traceback-outside-scenario error. Also addresses the prior re-review feedback on the same PR: - compose() return type was Any; tighten to collections.abc.Iterator[Any] so the generator shape is exposed to type checkers without taking a hard textual dependency at typecheck time (Iterator[Any] is the structural type of a Textual ComposeResult; we stay importable when textual is absent). - The Bug #10488 TDD scenario asserting action methods now also covers action_dismiss_screen so a future refactor cannot silently drop the escape binding without test failure. Verified locally on this worktree: - typecheck gate: 0 errors, 4 unrelated warnings. - unit_tests gate on features/tui_permissions_screen.feature: 65/65 scenarios pass. - lint gate: clean.
