      I've noticed during checkpoints early in a process's lifetime, the dirty leaf page count tries to decrement when it's already 0:

      {"t":{"$date":"2025-10-08T17:40:34.158+00:00"},"s":"E",  "c":"WT",       "id":22435,   "ctx":"Checkpointer","msg":"WiredTiger error message","attr":{"error":0,"message":{"ts_sec":1759945234,"ts_usec":158583,"thread":"279933:0xffff85be8200","session_dhandle_name":"file:collection-8cb0bf
45-bd78-4de4-b02f-5174b227f74d.wt_stable/WiredTigerCheckpoint.19330","session_name":"WT_CURSOR.next","category":"WT_VERB_DEFAULT","log_id":1000000,"category_id":12,"verbose_level":"ERROR","verbose_level_id":-3,"msg":"void __wt_cache_decr_check_uint64(WT_SESSION_IMPL *, uint64_t *, uint
64_t, const char *):459:dirty leaf page count was 0, went negative with decrement of 1"}}}

      We might want to consider crashing or asserting when in debug mode to catch it and fix the logic.
