def open.owner source · line 133 · raw

@caps:Caps -> IO(Pair(Chan(Command), Chan(Counts)))

The affine server owner joins this actual actor result after closing its listener.

@sent:Bool -> @+reply:Chan(Bool) -> IO(Bool)

def quiesce source · line 149 · raw

@+inbox:Chan(Command) -> IO(Bool)

False also covers copied controls used after actual controller closure.

@+inbox:Chan(Command) -> @kind:U32 -> IO(Bool)

def give.sent source · line 170 · raw

@sent:Bool -> @+reply:Chan(Unit) -> IO(Unit)

Correct owners cannot retire the actor while a lease remains counted. If an internal channel is externally closed, report the violation instead of joining an unanswered reply or pretending a retained operation drained.

def give source · line 179 · raw

@+inbox:Chan(Command) -> @kind:U32 -> IO(Unit)

def snapshot.sent source · line 185 · raw

@sent:Bool -> @+reply:Chan(Counts) -> IO(Maybe<&2, Counts>)

def snapshot source · line 198 · raw

@+inbox:Chan(Command) -> IO(Maybe<&2, Counts>)

A successful rendezvous send was received: Stop cannot erase a queued request. After controller closure a failed send returns None without waiting on its reply.

def close source · line 206 · raw

@inbox:Chan(Command) -> IO(Unit)

Retire accounting after listener closure; quiesce is the separate admission cutover. Finite internal fixtures may finish their already-accepted protocol.

Unsafe

unsafe loop source · line 79 · raw

@+inbox:Chan(Command) -> @+caps:Caps -> @+counts:Counts -> @+running:Bool -> @+closing:Bool -> @step:Step -> IO(Counts)

The private inbox is reusable: IO.join would close it after one receive.
