A round is one pass by every seat: the lead works, then each reviewer checks it.
How agreement is decided
A reviewer that fully endorses the work ends its turn with an agree token. When every reviewer has agreed, the discussion is settled: the lead writes the final answer and it stops. There is no vote and no averaging — one unconvinced reviewer keeps the room working.
If the round limit runs out first, the discussion stops there and says where it got to, including what was still disputed. That is a real answer too, and often the more useful one.
Rounds you get
On every plan the room keeps going until everybody agrees by default (at most 25 rounds), with your credit and any spending ceiling as the brakes. You can pin a number instead: Free allows up to 25, Pro and Team up to 6, and the room still stops sooner the moment everybody agrees.
You can pin a fixed number in Settings, or pick a Depth preset per discussion.
When it stops early
When the room stops without agreeing, a Give them two more rounds button carries on from where it was (it reads Keep going when rounds are set to run until they agree). Nothing is re-done; the transcript continues.
Plans, and then the work
When the room agrees on a plan but has changed nothing, the app does not stop and congratulate itself. In Edits, Auto and Bypass it carries straight on into implementing the plan, in the same discussion, counting on from the round it reached — one discussion, one conclusion. In Plan mode, where changing things is forbidden, it offers you the instruction instead so you can send it when you are ready.
