Detailed Description

One real execution owner, injected without OS dependency.

start SUCCESS borrows operation until service SUCCESS. BUSY or any start error retains zero operation references/hardware effects; an error after partial start must instead accept and report through service. service SUCCESS proves all hardware/IRQ/deferred accesses stopped, writes final result/count, and releases the operation. BUSY still borrows. Other service errors retain ownership and require continued recovery/service. cancel requests drain; it never by itself releases operation. Callbacks run only in the externally scheduled executor, outside adapter metadata guard.

Note: terminal_authority selects providers that observe deadlines and latch their first terminal hardware fact themselves. Their final result survives late cancellation/publication. Other executors use adapter deadline/cancellation results. Queued deadlines always belong to the adapter.
