This issue may be caused by a race condition during concurrent access. Since the keys are unshared, LoadOrStore is expected to safely handle them in parallel. However, the presence of unexpected keys in the map suggests that synchronization may not be working as intended.
Running the test with the -race flag might help detect data races. It may also be worth reviewing how CanonMap handles internal state for unique keys during concurrent operations, to identify any potential flaws in synchronization logic.
