Stopping hidden instructions

Quarantine: instructions are not memories

Text that tries to give the agent orders is stored, locked away, and only released by a person.

What gets caught

Text that tries to override instructions, switch the agent's task, change its role, extract its hidden prompt, or force a specific answer. Before checking, AETHER-33 undoes common disguises: look-alike letters, invisible characters, odd spacing and simple encodings.

What quarantine means

Why a secret and not just a name

If the agent could release its own quarantined memories, quarantine would be pointless. So the person who reviews sets a secret once and keeps it away from the agent. Set it before you give an agent access, because whoever sets it first holds it.

What it misses

This is pattern matching. A politely reworded attack, another language, or an attack that uses no obvious command words can get through. That is why the next rule matters most: even a bad memory that gets in can never grant permission. See “Memory is never permission.”

AETHER-33 is a product over CAIN-42's governed-memory stack, not a new architecture moat. Memory never carries authority: every response is annotated grants_authority: false. No third-party audit has been performed. Limits · FAQ · what is live now
