What

The caching behind session message loading was collapsed from three separate memoized caches into one memoized session-messages loader, changing what the reset helper has to clear.

Details
  • The reset helper now clears the single memoized session-messages loader instead of three caches.
  • A separate new helper clears two workload caches plus a nested one.
  • The test-reset path for another module switched from calling clearForTest() to clearing two maps directly.
  • No user-visible surface; failures during load still report through the same message.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
