formgoggles-py

Bounded, diagnostic-first procedure for verifying whether a pushed workout actually committed to FORM goggles. Use when: (1) testing changes to form_sync.py/full_sync.py BLE push logic, (2) investigating why transfers succeed (FILE_TRANSFER_SUCCESS) but workouts don't appear on the goggles, (3) any /goal loop over goggle sync. Hardware-in- the-loop: BLE is flaky and the device is irreplaceable mid-project, so this skill is as much about what NOT to do as what to do.
