== Chain of custody ==
At present, we can't make any statements at all about the integrity of the hardware before it reached us - assembled and ready.
We test and program the Alphas using a dedicated computer, but not in a secure facility by any means.
A concerned user is advised to reprogram the firmware with binaries built from source.
To provide some assurance the devices have not been tampered with after they have been programmed we put them in sealed bags with individual serial numbers.
As the model of bags might change over time, we will publish photos of the bags used here as well as PGP signed statements for what serial numbers can be expected.
At this time, we do not keep records of which exact unit was sent to whom.
This is a picture of the currently used bags:
