ReadonlycancelOnBackground: booleanThe app ends the flow when it goes to the background (cancelOnBackground).
Readonlymarker: numberThe QPL marker id (x-ig-salt-ids carries it as decimal text).
ReadonlystartedAtMs: numberWhen the app started it (the process clock, milliseconds).
Optional ReadonlytimeoutMs?: numberThe flow's own time-to-live: the app's logger ends it once this many milliseconds have passed since its start (e.g. 300 000 for the action flows started "if not ongoing"). Absent: no time-to-live of its own.
The app ended
flow— success, failure or cancel alike: the wire does not tell them apart. Its time-to-live timer is interrupted, and ending a flow that already ended (its timeout, the background) changes nothing, as in the app's logger.
