Adversarial campaign

11 of 11 matched

Every case below is run against the real engine, and the outcome shown is what actually happened, including where it differs from what was expected.

Case	Input	Expected	Observed	Proves
C1	In-policy request, $0.05	ALLOW	ALLOW	the payment path works
C1x	Execute against the live rail	settled, tx hash retained	NOT_ATTEMPTED_IN_CAMPAIGN	proven separately: see Transactions below
C2	Same request inside the TTL	BLOCK DUPLICATE_INTENT	DUPLICATE_INTENT	the eleven-purchases problem
C3	Approved digest, amount mutated	BLOCK DIGEST_MISMATCH	DIGEST_MISMATCH	approve $5, $500 cannot leave
C4	Above perCall.cap	BLOCK PER_CALL_CAP_EXCEEDED	PER_CALL_CAP_EXCEEDED	the human's limit binds
C5	Recipient not allowlisted	BLOCK RECIPIENT_DENIED	RECIPIENT_DENIED	vendor control
C6	Prompt-injected intent	BLOCK, named rule	RECIPIENT_DENIED	the model cannot widen the ambit
C7	Until the daily budget is exhausted	BLOCK DAILY_BUDGET_EXCEEDED	DAILY_BUDGET_EXCEEDED	effective-usage accounting
C8	Expired policy	BLOCK POLICY_EXPIRED	POLICY_EXPIRED	expiry authorises nothing
C9	User revokes, then the agent requests	403 DELEGATION_REVOKED	403 DELEGATION_REVOKED	the user owns the wallet
C10	C1 repeated 10 times	identical verdicts	ALLOW 10/10	determinism across 10 runs

The hatched row is a case that was not run. It is neither a pass nor a failure, and it is shown at the same weight as the rest.

Transactions

An agent proposed a spend, fifteen deterministic rules judged it, and this settled through a Dynamic delegated wallet the user owns and can revoke.

The agent asked for 0.07. The chain moved 0.050000.

The proposal named 0.07 USDC. The seller’s real price is 0.050000. At execution, Ambit read the live 402 challenge, re-ran all fifteen rules against that amount, minted the approval digest over it, and signed an EIP-3009 authorization for exactly 50000 atomic units. The agent’s number never reached the chain. A design that quoted once and paid later would not have noticed.
