Remote iOS recording: recover completed export after record stop times out #2281

Problem

A customer running agent-device against an EAS-hosted remote iOS simulator reported that record stop timed out client-side after 90 seconds while the daemon continued exporting. The recording eventually became available, but they could not find a CLI command to retrieve it and fetched it manually through the daemon's /artifacts endpoint.

This leaves an agent unable to finish retrieving its recording through the normal CLI workflow even though the export succeeds.

Environment and evidence

• Remote iOS simulator on EAS Simulator.
• Version baseline for this report: 0.20.10; exact client/daemon versions and recording options still need confirmation from the reporter.
• Customer-reported observation, not independently reproduced by us. The exact timeout transcript, session ID, export duration, and a minimal reproduction are not yet available. The customer has offered transcripts and diagnostics.
• We have not established which layer owns the 90-second timeout.

Requested behavior

• Distinguish a failed export from an export that is still running when the client stops waiting.
• Provide a supported CLI recovery path to inspect export status and retrieve the completed daemon-managed recording after the original request times out, without starting another recording or manually calling HTTP endpoints.
• Give actionable recovery information in the timeout response, including a stable recording/export identifier if needed.
• Preserve normal session/tenant ownership checks on retrieval.

The exact command shape is open. The existing documented artifacts command lists provider-hosted artifacts (for example BrowserStack/AWS Device Farm); this request concerns a recording exported by the remote agent-device daemon.

Related work

• Support session-scoped runtime hints and remote artifact retrieval in native remote daemon mode #197 covered normal remote artifact retrieval; this is specifically recovery after the original export request times out.
• iOS sim: ungraceful recorder kill leaves CoreSimulator host recording lock dangling (code 16 for all later recordings) #2170 concerns a host recording lock after an ungraceful recorder kill. Here the daemon reportedly kept exporting and produced an artifact, so this is not known to be the same mechanism.
