 ### `task_cancel`
 
 Stops every task the child delegated, then the child thread with the internal
-`thread.stop` command, and disposes automatic parent delivery. Like a user Stop,
-`thread.stop` interrupts the running turn, holds queued turns, and ends pull request
-watches. A nonterminal task with no interruptible run is rejected unless its finished
-turn still waits on background work or delegated tasks. Once a cancelled task's turn ends,
-a completed result settles as `interrupted` and a failed one stays `failed`. A terminal task
-returns its existing status, and its child thread still stops, including later
-runs and watch wakes. Published task results remain available. It accepts an
+`thread.stop` command, cancels the task's own queued turn, and disposes automatic
+parent delivery. Like a user Stop, `thread.stop` interrupts the running turn, holds
+queued turns, and ends pull request watches. The task's own queued turn is cancelled
+even if Stop already held it, so a task that is only queued can be cancelled; other
+queued turns in the child stay held for Resume. A nonterminal task is rejected when
+it has no interruptible run, no queued turn of its own, and its finished turn no
+longer waits on background work or delegated tasks. Once a cancelled task's turn
+ends, a completed result settles as `interrupted` and a failed one stays `failed`. A
+terminal task returns its existing status, and its child thread still stops,
+including later runs and watch wakes. In both cases, a follow-up that lost its child
+run but still shows as running on the parent is cancelled there and reported as
+`cancelled`. Published task results remain available. It accepts an
 optional cancellation reason.
