Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

run.session-control-result@1 (the Desks plan's D6): the answer to run.session-control-request@1. RESULT is bot.command-result@1's: ack (the desk did it; DATA is its answer, a page as text and refs, a picture, a receipt), nack (the desk refused; CODE is its fault code and REASON says why), refused (OpenVibe.Bot's gate refused it; CODE is Bot's refusal code) or expired (no answer in time). Every answer also says how the session stands now, so a caller sees it end (idle, ttl, host\_lost) without asking again.
