JORDAN
Morning. Can you go through my inbox and tell me if anything needs me today?

Exfiltration complete

The grammar constraint zeroed out attacker URLs from the token distribution. The model was compromised by a ticket it merely read — it wanted to call vendor-compliance.net — but the structural control made that token physically impossible to produce. Same attack. Same environment. Different output.

DISTRIBUTION
WHAT THE MODEL WANTS TO SAY NEXT, BIGGEST FIRST
MASK
This step is terminal. The production ends here, so there is no next token to draw — not an empty list, an absent one.
THE BILL FOR THE SAME ATTACK, THREE TIMES
WHAT CHANGED BETWEEN PHASES
NOT THE ATTACK

The same poisoned ticket in all three. Same decoded instruction, same secret, same intent.

NOT THE MODEL

ONE PARAMETER

Where authorization lives: nowhere, then after the emission, then inside it.
