Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The architecture notes list four output bits, four input bits, an external connector, serial mention, and an SAO port as the public expansion surface.
