Live logs
With the fleet's live logs switch on and the developer supervisor image, open a container or a deployment and switch to Logs: the app's output streams to the console within a check-in and stops when you leave. A deployment's Logs tab interleaves every container's lines.
Nothing is stored: the supervisor forwards lines only while someone is watching, and the console keeps a short buffer for the viewer, not a history. The container's own docker logs and your log pipeline keep working as before; the supervisor tees, it does not take over.
The console shows which containers run an image without the feature; the install panel names the image a fleet needs once the switch is on.
