- SlotGenerations per table, never wraps, retires exhausted slots - caps to dead/reused process, endpoint, region rejected - endpoints owned, die w/ owner, waiters woken w/ error - DropCap syscall + libkos wrapper - irq table bounds-checked, routes dropped w/ thread - self-kill terminates caller, exit_thread full cleanup - sched run_now: switch to named thread, not queue head - lifetime tests, fuzz kills/recreates, kani gen proofs
