Risk

Every order is checked inside the desk contract before it reaches Perpl, and equity is re-checked after the fill in the same transaction. The authoritative list of rules, their limits and what enforces each one is on the landing page's risk table and in SECURITY.md; the code is contracts/src/Desk.sol (_trade). Tests: contracts/test/unit/DeskPolicy.t.sol (28) and contracts/test/security/Attacks.t.sol (24). Testnet evidence: a 6x order sent directly to the desk reverted LeverageExceeded (proof/receipts/testnet/testnet_canonical_guarded_rejection.json). Imprest makes no Sybil-resistance claim; the paired-desk self-attack and the caps it calibrated are in DECISIONS.md (D-009).
