DEVLOG #14

Since the last devlog, I published a new Observatory Control Center and a
guided calibration workflow for the D6 experiment.

The setup now includes a CAD-style room editor for the TX and RX1–RX4
positions. It validates room boundaries, duplicate receiver positions, and the
canonical node IDs. The continuous mmWave calibration route is now the primary
workflow; the manual P01–P09 grid remains only as a legacy fallback.

Experiment profiles, run phases, setup hashes, and prediction/truth artifact
hashes are persisted in SQLite. The UI also makes READY, RUNNING, PASS,
OFFLINE, and SOFTWARE-ONLY / UNVALIDATED states explicit, so a simulated
workflow cannot be mistaken for a real sensor result.

I ran 41 UI/Observatory tests and 4 targeted Rust workflow tests; all
passed. This validates the software workflow, but not the real CSI stream,
LD2450 UART/UDP path, calibration data, or position accuracy.

Next: connect the LD2450 to the working ESP on the breadboard, verify UART
bytes and valid radar frames, and then continue with the sealed hardware
workflow and real blind tests.
