Four kinds of things show up on the timeline: what you said, what it said, what it did, and the nodes it produced. Once the jobs it handed to the background (image / video generation and the like) have all settled, the timeline also gains a gray receipt line on its own — which ones made it, which ones didn't, without you watching the canvas.
The order means something: it says what it is about to do, then does it, and gives you a summary at the end. So those gray lines in the middle read as a running log of the turn — what worked, what didn't, no guessing.
While the turn runs, a gauge row sits at the bottom of the message list: a spinning orb, a word on what it is doing right now (Thinking… while waiting for the model to speak, Replying… while words are streaming out), with elapsed time ticking by the second and credits climbing alongside; when it hands work to the background, a "N tasks running" chip joins the row — open it for a list of each job's node and stage, and click one to jump to that node on the canvas. If the request itself fails (network, upstream), the timeline gets a "The request failed" line with a Retry button — it runs the same message again as it was, and whatever the model had already said before it broke stays on screen; when there is a plain reason (most often not enough credits), that sentence is written right on the failure line.
When a turn has finished talking, the last line carries a row of small actions: Copy takes everything it said this turn (joined across tool lines and question cards); Dislike tells it the turn missed (a feedback dialog opens and sends the problem from that turn so it answers better next time); Retry only hangs on the last turn. Your own bubble has the same row underneath — Copy takes what you said, Retry sends that message again. A finished turn also keeps its account at the right end: "3 minutes ago · ⚡42" — click the number for this turn's usage breakdown.
Two more kinds of bubble turn up on the timeline that are not things you said; each has its own look, so neither gets taken for your typing:
- A platform note — its title reads "What the platform sent the agent". It is the platform speaking on your behalf (a pre-delivery self-check did not pass, or the Agent stopped halfway and the platform tells it to carry on), and it sits on its own; you do not need to answer it.
- "The N pictures the agent looked at" — the pictures it looked at this turn (previz frame sheets, comparison images and the like); open it and there they are. What it looked at is one more clue for judging whether the result is right.
