Variable: RUN_CANCEL_REASON#

const RUN_CANCEL_REASON: "tanstack-ai:cancel-requested" = 'tanstack-ai:cancel-requested';

Defined in: packages/ai/src/activities/chat/cancel.ts:30

Abort reason that marks an abort as an explicit cancellation.

Namespaced so an application's own reason string cannot collide with it by accident, and matched with === (never a substring test) so an arbitrary provider error message can never be read as a deliberate cancel.
