M4B audiobook

One signature-verified, unencrypted MP4-family audiobook up to 1 GB. This first release advertises fixture-proven AAC-LC audio.

I have the right to process this audiobook and understand that DRM-protected files are rejected without decryption attempts.

Reads stored chapters, primary audio properties, duration, codec, sample rate, channel layout, and cover-art presence.
Rejects missing, zero-length, overlapping, out-of-order, out-of-bounds, encrypted, malformed, and non-audio chapter sources.
Creates private CSV and JSON manifests with normalized timing and bounded warnings.
Uses neutral chapter-0001 names. Titles never enter URLs, logs, analytics, ZIP entry names, or download filenames.
Does not accept remote URLs, playlists, user timestamps, chapter edits, archives, or custom FFmpeg switches.

Results are private, served with no-store headers, retained only for the existing download window, and then cleaned up automatically.
