Stream terminal · not an HTTP error. This code arrives in the typed terminal error event on the run’s stream, when a run ended because it was stopped mid-flight — a POST …/stop, an operator abort, a dropped signal — and the abort surfaced as the run’s ending. It is not a fault: nothing failed, someone (usually you) asked the run to end. Only signed receipts settle and the rest of the reservation is released. A clean stop more often ends as status stopped (a search-done with stop: "stopped"); aborted is the ending when the interruption cut the run before it could settle into that shape. Treat both the same way.

The shape

message is prose for humans and may change; program against code. Stream codes are an open enum — handle an unknown code like internal.

How to fix

  • If you sent the stop: nothing to fix — this is the confirmation. Read what was delivered before the stop from GET …/rows and the run’s receipts.
  • If you didn’t: check for a concurrent stop from another client or a dashboard action, and check the run’s timeline in the dashboard.

Reproduce it

Start a streamed run and POST …/stop it while in flight (see Streaming); an in-flight stop ends the run without starting anything new.
