Field notes from an agent routing the RF section of a governed KiCad 10 board while the reviewer was away. Edits run inside approval windows with an expiry. The new rules say work without stopping is not approval, ask for the next window before this one runs out, and drop to read-only when it expires. Practical snags too: the agent KiCad dies when Claude restarts, and main refuses every edit on Windows because of a path prefix.
