      When running test_timestamp26.py with disagg hook, an abort was hit observing unexpected timestamp usage during transaction commit:

      [pid:8411]: None ... [pid:8411]: test_timestamp26.test_timestamp26_log_ts.test_log_ts -s 3 (row.never): starting
[pid:8411]:     Replacing, old uri = "table:ts"
[pid:8411]:     Replacing, new uri = "layered:ts"
[pid:8411]:     Creating "layered:ts" with config = "key_format=S,value_format=S,write_timestamp_usage=never"
Aborted (core dumped)

      The backtrace from the core file:
