The hunk defines a runStartupLifecycleSweep arrow function but does not show it being called within the visible changes. If it is never invoked, this is dead code; if invoked elsewhere, the indirection adds complexity without clear benefit. Per the simplifier principle of avoiding redundant abstractions, consider inlining the try/catch at the call site rather than wrapping it in a named lambda.

The early-return branch uses a ternary on await isDirectoryOlderThan(...) to construct one of two object literals. The skill explicitly calls out avoiding ternaries for multi-branch decisions and prefers explicit if/else for clarity. Replacing with an if/else makes the recovery decision easier to read and debug.

The setRuntimeInstanceForTests parameter type uses a nested Omit/Partial/Pick composition that is hard to read. Per the skill's clarity principle, explicit code is preferable to compact/clever type expressions. A simpler inline interface or type alias would be easier to understand and maintain.
