## Blueprint

**Open firmware.** Firmware (AGPL-3.0), enclosure STLs, assembly manual and a parts BOM are public; the custom DIGI Node PCB is sold bare with no schematic or Gerbers published.

_Notes:_ AntiHunter repo (AGPL-3.0, 674 stars) tree confirmed via gh api: hw/ folder has only 3D-printed enclosure STLs, an assembly-manual PDF and a BOM-Links.md that itself points buyers to 'DIGI PCB — AntiHunter Lectronz Store' for the bare board — no schematic/Gerbers for that PCB are in the repo or linked from it.
