+**Ownership gap (resolved):** was unassigned. `f10-coder` is on RM-02's blockers, `coder-mos1` on RM-03, `rev-974` is the
 reviewer, and no other seat holds mosaicstack write. Flagged to the coordinator rather than stacked onto a
 busy lane. Not blocking today — RM-02's code blockers are independently disqualifying — but the next
 otherwise-clean PR meets this.
