U225X PUBLIC SUMMARY
Record: ERR-STICKER-QR-001 / Engineering Sticker Set and QR Code Failure
Status: Abandoned / Graveyard

SUMMARY
The sticker work established a coherent visual family around engineering, fishing, smoke, gnomes, and rebuild themes. The QR branch was abandoned because generated artwork could look correct while encoding the wrong modules or failing to scan reliably.

LESSONS
- Treat a QR code as a separate machine-readable asset, not decorative artwork.
- Generate the code with a real encoder, place it as a controlled layer, and scan it at final print size.
- Test after export and after printing on more than one phone.
- Keep exact locations and private details out of public sticker artwork.

RESULT
The sticker language worked; the decorative QR did not pass reliable verification. The record remains available as a design lesson, not as a claim that the abandoned code is functional.
