Background

WT-18355 fixed __curstat_layered_init to route tables created during the step-down window (WT_LAYERED_TABLE_STEP_DOWN_CREATED) through the follower path, which tolerates a missing stable constituent. As a belt-and-suspenders measure, a bare ENOENT guard was also added after the leader path to cover a role-transition race.

Investigation Needed

Determine whether the ENOENT guard is reachable in practice. The flag check should cover every table without a stable constituent. If the flag is always set before a leader could reach the stable dhandle open with no matching metadata row, the guard is dead code and can be removed.

The guard lives in src/cursor/cur_stat.c, _curstat_layered_init, after the _wt_session_get_dhandle call on the stable URI.
