There's no git usage, they're just storing a snapshot of each repo's current HEAD in a TAR file (and then compressed and QR-encoded).

> The snapshot will consist of the HEAD of the default branch of each repository, minus any binaries larger than 100KB in size—depending on available space, repos with more stars may retain binaries. Each repository will be packaged as a single TAR file.

The guide included on each reel about how to access the data is public, git isn't involved in the process: https://github.com/github/archive-program/blob/master/GUIDE....

No, it is not QR-encoded.

This is the method:

In the link you post it states "piqlWriter: data writtenas high-densityQR codesEncode binary data to 2D barcode (apply Forward Error Correction)Modulate light using a Digital Micromirror Device (DMD) to project the barcode on the film."

It's a lie. It's not a QR code. I don't know why they say it is. Look at the code. It's nothing like a QR.

They should have said "2D Barcode" but they might be assuming an ignorant audience.
