- flushStatementAfterCommit marks the statement; AfterCommit logs a warning
when work is buffered on a flushed statement that no longer holds GORM's
transaction. Log-only: the work still never runs, the write succeeds
- subtests pin the late callback warning, a callback between commit and
flush, and a reused chained statement staying silent
- README OnDatabase example registers After(gorm:create).Before(commit),
matching docs/database/transactions.md
- RegisterJoinTable: pivot-ordered reads join the pivot table explicitly;
a Preload cannot be ordered by a pivot column
