Enum Plan 

pub enum Plan {
    LocalReuse(Lease),
    RemoteReuse(Lease),
    Create(CreationPermit),
    Wait(u32),
    Reject(Reason),
}

What Pool::acquire committed to. Reuse variants hold a reservation already taken; Create holds creation budget already claimed. Neither is advisory.

Variants

LocalReuse(Lease)

Capacity reserved on a resource this process owns: execute here, no stream, no shared-memory hop.

RemoteReuse(Lease)

Capacity reserved on another process’s resource: bring the lease to the owner over a stream; the owner accepts and completes.

Create(CreationPermit)

Budget claimed: make the resource, register it, finish the permit.

Wait(u32)

Nothing usable now; wait past this key version and ask again.

Reject(Reason)
