- Move TStepLaunchMetaData type definition from serialize.py to controller_utils.py - Remove unused smartsim/_core/utils/serialize.py file entirely - Add pathlib.Path import to controller_utils.py for type definition - Remove TYPE_CHECKING import that was only used for the moved type - Complete final cleanup of telemetry-related serialization code - All functionality preserved and tests still pass
- Replace Union[X, Y] with X | Y syntax across entire codebase - Replace Optional[X] with X | None syntax - Update List[X] to list[X] and Dict[X, Y] to dict[X, Y] - Update Tuple[X, Y] to tuple[X, Y] and Set[X] to set[X] - Modernize collections.abc imports (Callable, Iterable, etc.) - Remove 46 unused 'import typing as t' statements - Fix dict type annotations with union syntax for mypy compatibility - Update 100+ files with modern type hints - Maintain 10.00/10 pylint score - Achieve 'Success: no issues found' mypy validation Files affected: 93 core files across smartsim/ and tests/ Type safety: All existing type annotations preserved and improved Compatibility: Python 3.10+ syntax with backward compatibility
- Remove incorrect quotes from os.PathLike[str] in union type - Fixes runtime import error in builder.py - Union should be: str | os.PathLike[str] (not str | "os.PathLike[str]") - Maintains proper type safety and Python 3.10+ union syntax
- Remove incorrect quotes from os.PathLike[str] in union types - Fixes 2 additional instances of the same issue as builder.py - Function parameter: str | os.PathLike[str] (not str | "os.PathLike[str]") - List type annotation: list[str | os.PathLike[str]] - Ensures all SmartSim modules can import without syntax errors

LGTM, thanks for moving everything over to using collections.abc while you were here!!
I left a couple of last minute Optional -> | None suggestions, but otherwise, this all looks 1-to-1 to me!
