module	does
`cortex.py` / `fake.py`	one Cortex session; `dev` always co-subscribed; fixture replay
`state.py`	ring buffers, bands, pose
`events.py`	debounced reflex events
`tools.py`	`@tool`s + `ambient_line()`
`agent.py` / `agent_api.py`	Strands agent, SSE streaming, markers
`recorder.py` / `dataset_v3.py`	LeRobot v3 writer (pyarrow)
`server.py`	FastAPI, WS fan-out, static

Measured limits: Basic license denies eeg (-32016) → pow is the source. attention only when Cortex's detector is active → nothing gates on it. fps=8 = pow rate.

The mark·

Green strand: the Strands agent. Teal strand: the person, with an EEG signal running along it and a marker stamped where the two cross.
