Preserved files

• original/CODE_UPLOAD36782282000.psc is the byte-for-byte file from the first Planet Source Code Visual Basic CD image.
• original/CODE_UPLOAD36782282000.zip is the decoded original submission. PSC encoded the file by complementing every byte; XOR with 0xff restores the ZIP. unzip -t verifies all seven members without errors.
• git/alan-dipert-problemscan-v1-0__1-6312.bundle is a complete bundle of the reconstructed Planet Source Code Git repository, including its master branch and original-zip tag. The original ZIP above is the authoritative copy for original filenames, timestamps, and line endings.

The decoded ZIP contains the two VB forms and resources, Project1.vbp, the VB workspace file, and Planet Source Code's generated readme. It does not contain a compiled executable.
