.mdr — The P3AK Document Format

Overview

One file. Everything inside.

A .mdr file is what happens when a document enters the P3AK ecosystem. It wraps your original content — whether from a PDF, Word doc, spreadsheet, or audio transcript — in a structured envelope that carries its complete history, access tiers, and metadata. Pull it open in any text editor and read it. Ingest it into a vault and search it. Export it back as a branded PDF. The data never disappears.

Note on source_hash: The SHA-256 hash of the original PDF is stored in the header. If the source file changes, the hash changes — making tampering detectable. The original PDF is preserved separately; the .mdr holds the extracted knowledge.

Markdown is the simplest case: the source file is already in the right format. P3AK prepends the structured header and the @@@ layer @@@ delimiter — no content transformation required. Zero data loss, zero ambiguity.

Versioning

Every change. One file.

When a document is updated, the new content is prepended as a new layer block. Prior versions are never deleted — they're preserved below the current version with their original timestamp and author. One .mdr file holds the complete history of a document, forever.

P3AK vault only indexes the current version (the topmost @@@ layer @@@ block). Prior versions are preserved in the file but not surfaced in search — unless you explicitly request them with --version 1. Nothing is ever lost.

Export

Back to PDF — branded.

Any version of any .mdr document can be exported back as a formatted PDF. P3AK applies your organization's branding, adds a tamper-evident metadata footer, and stamps which vault version the document came from.
