- monitor(watched, observer, msg): registration lives on the watched
actor's home thread (kind-7 envelope cross-shard); actor_die walks
the list; already-dead fires NOW; the notice msg moves; a full
observer's notice drops with a stderr line (no fiber to trap)
- time.after(ms, addr, msg): per-shard timer list riding the deadline
machinery (uring tick min + epoll timeout both include timers;
fired from the same sweep); ms <= 0 delivers now; NO cancel — the
generation-counter idiom is pinned by run/timer-generation
- runtime_notify: one runtime-sourced delivery path (notices, timers) —
reserve-or-drop, cross-shard via kind-0 envelopes
- compiler: monitor typed as a bespoke free fn (notice typed against
the OBSERVER's mailbox — the three-argument deviation, disclosed);
time.after as a stdlib row whose msg arg is EXEMPT from the module-
call fresh-arg drop (it moves — the double-own bug the timer fixture
caught); owner move slots for both
- corpus: run/monitor-death (trap-death + already-dead notices),
run/timer-delivery (armed + immediate), run/timer-generation
- teardown drops undelivered notices and unfired timers; battery 13/13
