Exhibit inventory (read as text)
FCC internal/external photos and report text, re-read on the second pass
for silkscreen, chip markings, test points and labels — not for
hero shots. Source files: research/fcc/ in the companion repo.

Corrections this pass
- Half mainboard photo shows V11 silkscreen (20250220); the earlier
KB table said
V13. The live unit's rev may differ from the filing
rev — recorded as the filing's rev here, with the table updated to
note the V11 exhibit.
- Module MCU (STM32F411CEU6) was already correct in the hardware
table — the second pass confirms it on die and adds the per-module
ring board names (Tune/Track).
