MANU Protocol reproduction scripts

Companions to the CTF retrospective. These scripts read local challenge evidence; they do not submit flags or contact the event.

Requirements: Python 3; NumPy for audio/image scripts; Pillow for PNG extraction; pypdf for PDF metadata; Git for timestamp extraction.

The original event files are not included. Pass their paths as shown in the article. Radio CTF 02 has no retained historical ciphertext; its helper can only be tested with synthetic data unless you kept the packet. Other original-input checks are described in the source pack's historical verification report.
