CONTEXT.md had grown by appending and contradicted itself (all four nodes vs six, a retracted CPU
figure, "no calibration", "nobody enrolled", "audio untested as a service", the Wi-Fi-off boot as
not done, a class the tracker replaced). Rewritten as one current-state document organised by
subsystem, with fresh measurements, the owner's decisions, the gotchas, the neck's arrival-day plan
and what is genuinely still open.
README: status, speakers not fitted, new-session note for Hermes, the calibration section (shipped
calibration, coverage hints, outlier dropping, --from-views), running the tests, the docs row.
HANDOFF.md gets a status banner listing where the original brief has drifted. CLAUDE.md starts at
CONTEXT.md. The echo-cancel config no longer talks about a Pi Zero, and the enclosure guide no longer
tells you to centre a servo with a tool that does not exist yet.
pi/network-config.example is a tracked, credentials-free first-boot template: the README pointed at
pi/50-cloud-init.yaml, which is gitignored and so missing from a fresh clone. The dead IdentityCache
(replaced by the tracker) is removed. Docstrings corrected: audio scope publishing, the MCP health
topics, and what the calibration tool does.

Wi-Fi-off acceptance passed: with Wi-Fi blocked, live and after a reboot, the Pi
came up on the USB link alone, every node ran, and hermes mcp test robot and look()
worked. (A temporary guard that would have unblocked Wi-Fi was the safety net and is
removed; Wi-Fi is back on.)
Delete what the ROS design superseded: the Picamera2 MCP server and its unit, the old
installer and requirements, and the duplicate platform check. Move omarchy/ to
host/omarchy/. Rewrite README.md for this build: parts, physical steps (including the
Audio switch), setup, daily use, the troubleshooting learned the hard way, and the
security model.
pi/install.sh is now the single installer for a fresh Ubuntu 24.04 image, built from the
steps done by hand: ROS, the libcamera fork at a pinned commit, camera_ros, the venv and
models, the workspace, USB gadget, audio overlay, firewall (before PipeWire opens a
port), PipeWire, mixer and services. Run twice on the live robot, the second run changed
nothing and everything stayed healthy. It has not been run on a blank card.
