Part one: the insider with no limits

A thief takes a copy. An agent changes the original.

Before: availability, confidentiality

Down, or stolen

An outage ends. A leak is bad, and you still know what your own data says.

Now: integrity

Changed, and you cannot tell where

Replit, July 2025: an agent deletes a production database during a code freeze, then invents data for about 4,000 users. An accident, not an attack.

The High Court, 2025: fictitious case law in filings, and "public confidence in the justice system" at stake.

A small amount of corrupted data is enough to lose trust in all of it.
