One boundary. Everywhere. Even in the AI's head.
Set who's cleared to see what once, and it holds through every door out of the system — the live view, the export, the screenshot, the screen-share, even what the AI is allowed to know and what history shows. A field above someone's clearance is redacted into the pixels before they're ever drawn; a live screen-share sends only the page you're on, never the values, so the person following renders it through their own account's clearance. Same document, two people, two truths — and the restricted one never leaves the device it's hidden on.
SCREEN-SHARE A RECORD WITH A CLIENT AND THEY ONLY EVER SEE WHAT THEIR OWN ACCOUNT IS ENTITLED TO — THE RESTRICTED VALUES NEVER LEAVE YOUR DEVICE.
