What the agent sees

[brain: focus 0.71↑ · stress 0.22↓ · alpha dominant O1/O2 · still 38s · CQ 13/14 good]

focus attention (+ delta arrow) · stress · dominant band + top 2 channels · seconds still · electrodes at CQ 4.

It never mentions the line unless it matters. It changes behavior:

you	it
stress ↑, task failed	3 lines, 1 next step, no questions
focus dropped mid-answer	one-line summary
alpha up, still 40 s	shuts up
engagement rising	pulls the thread
CQ < 10/14	normal assistant, says so
