Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The badge exposes two Shitty Add-On V1.69bis connectors and an IR pairing connector, giving attendees both add-on and badge-to-badge interaction surfaces.
