BUILT CAREFULLY UNDER THE HOOD
Simple for users. Strict with the hardware.
The friendly interface sits on top of a conservative device model: hardware readback is authoritative, preset files are validated, unknown commands stay read-only, and permanent writes use verified transactions.
Hardware-firstFull device readback before LIVE editing.
Preset integrityValidates native .k500 containers and preserves unknown bytes.
Fail closedUncertain destructive actions stop instead of guessing.
