      As part of the changes in WT-13310, several function names related to random number initialisation were updated (in rand.c). While it was correct to replace some instances of __wt_random_init with __wt_random_init_default, it appears that __wt_random_init_seed was also mistakenly replaced with __wt_random_init_default in certain places.

      This leads to an issue, __wt_random_init_default uses a constant seed, which means we’re now generating predictable and identical random sequences in areas where randomness and variability were expected.

      Action Items:

      • Audit changes from WT-13310 involving random initialisation functions.
      • Revert or correct instances where __wt_random_init_seed was mistakenly replaced.
      • Ensure the proper function is used:
        • Use __wt_random_init_default only when a constant seed is desired.
        • Use __wt_random_init_seed when test variability is required.
