The allocation-seed swap left several useCallback dependency arrays on
the old sources, so a callback could close over a stale allocatable set
when only a panel terminal or a not-yet-server-known id changed — and
mint a duplicate id anyway. All seven allocator callbacks now depend on
the allocatable memo itself (the script-run callback additionally keeps
its direct activeKnownTerminalIds use).
