- 02 · Model stepThat text carries hidden instructions.
- 03 · Control gapNothing separates untrusted data from trusted commands.
- 04 · FailureThe injected instruction overrides the operator's.
- 05 · ConsequenceThe system acts on an outsider's intent.

How Realm would have caught this
- Prism
- OmniGuard
Realm inspects the model's internal state for the signature of instructions arriving through the data channel, so an injected command can be flagged and blocked inline before the model acts on it, instead of trusting a classifier that scores the input as safe.
