Studio custody mark for masters that leave the room.
Protect the file. Keep a receipt. Check the mark after a messenger handoff — without pretending the courtroom already decided.
Why studios use it
Two complementary hidden layers in a finished stereo master — built for leak-source / seat+asset signal, not as “unbreakable DRM.”
Each Protect run stamps a track identity tied to your licensed seat. Another licensee’s Detect does not match your marks.
Field-tested path: send as a file (Telegram / WhatsApp-class) → download → Pre-Flight still lands YES or an honest MAYBE.
Survives common digital crops / mid-section excerpts used in demos and disputes — Pairwise confirms disputed vs marked reference when you need counsel-grade evidence.
Designed to hold through lossy / lossless re-encode, normalize, mono fold, and everyday file copies — the transforms that actually happen after a master leaves the desk.
Hidden in the finished stereo — no audible “watermark taste” on a working master when used as specified.
Desktop app after install: no cloud, no telemetry, no account login. Protect → receipt → self-check on your machine.
YES / MAYBE / NO — including when the answer is uncomfortable. Better a clear MAYBE than a fake green light.
