Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The Supercon version added proto-board support and documented GPIO, I2C, serial, and SAO-style expansion paths for attendee-built peripherals.
Badge context
