* fix(codex): the provider supervisor outlives its provider group when stopped A signalled supervisor forwards the signal to the provider group, escalates to SIGKILL after the grace, and exits only once the group is gone, so recovery's proof that the recorded pid is dead also proves the provider is. It refuses to spawn when its parent is already not the owner named in its spec, and watches that owner rather than whichever parent it first saw. The grace is a spec field. Recovery's SIGTERM stage now outlasts the supervisor's own stop, since a SIGKILL that lands first cannot be handled and leaves the group running. * fix(codex): a closed owner pipe no longer ends the supervisor before its provider group When Orca dies, the supervisor's stdout pipe has no reader. Provider output in the window before the parent-death watch fired raised an unhandled EPIPE that exited the supervisor with the provider group still running. * fix(codex): bound the supervisor grace so recovery's SIGTERM stage always covers it Recovery sized its SIGTERM stage from the default grace, so a launch with a longer grace would be SIGKILLed mid-stop and orphan its group with no test noticing. The spec now refuses any grace above one exported maximum, and recovery derives its SIGTERM stage from that maximum. * fix(codex): every supervisor stop asks the provider with SIGTERM first Owner death, stdin end after the grace, and a signal to the supervisor now all take one path: SIGTERM the provider group, SIGKILL it after the grace, and exit only once it is gone. The signal handlers are registered before the provider is spawned, so a stop that lands in the spawn window still reaps it. The longest stop grows to two graces plus the reap wait, and both recovery's SIGTERM stage and the connection's graceful close now wait that long before forcing, since forcing the supervisor sooner can orphan its group. * fix(codex): give the provider 1 s after stdin end and 3 s after SIGTERM to flush before SIGKILL The supervisor's stop was stdin end, 1.25 s, SIGTERM, 1.25 s, SIGKILL. Codex now gets 3 s after SIGTERM to flush its state. The two graces are separate constants, the longest stop they derive becomes 5.5 s, and a test keeps it inside quit's 8 s child-eviction bound. * test(codex): count eviction's pre-stop drain in the quit budget test Eviction drains the sink for up to 1 s before it stops the child, inside the same 8 s bound.
