What the ZIP contains
Every transformation is mapped. Every failure stays visible.
Readable chronology
A print-ready HTML review shows observed headers, inert body text, warnings, and attachments.
Extracted attachments
Attachments are copied and hashed. They are never opened, run, or recursively unpacked.
Integrity manifest
manifest.json maps sources, MBOX byte ranges, review output, hashes, duplicates, and failures.
Claim boundary
Hashes show change. They do not prove truth.
SHA-256 helps detect whether bytes changed after import. It does not prove who sent a message, whether it was delivered, whether the mailbox export is complete, or whether a court will admit it.
This is document conversion and an integrity report—not legal advice, authentication, e-discovery collection, or forensic certification.
