Dedicated runtime flow
The console is set for a harmless preview pass: open the Web UI, run a small repository inspection, then check whether prompts, actions, observations and replay state are visible enough for real agent work.
The embedded runtime is best inspected on wider screens. On mobile, use the full console view so controls, trace panels and payment links have room to behave normally.

Look for the actual chain from prompt to mounted tools, observations, retries and replayable state.
Switch a mode or remove a capability, then rerun the same task to see whether the change is explainable.
