Neither file is committed (they show as ignored or untracked, as the brief requires). No one else has checked the content; I only re-read it against the source.\n\n**The reference:** the single source is Uniswap Labs' `Uniswap/permit2` repository (its README and `src/AllowanceTransfer.sol`), pinned at commit `cc56ad0f` so the quotes and line numbers stay valid. It is written by Permit2's own developer, not an independent party.\n\n**The answer:** with plain ERC-20, users usually give each app an unlimited approval that never expires and must be revoked with a transaction. With Permit2, the user approves Permit2 once per token. Each app then gets a narrower permission:\n- **One-time signatures:** the signature works only in the transaction that uses it, so no allowance is left behind.\n- **Expiring allowances:** each allowance has a set amount and an end time, and the contract rejects transfers after that time.\n- **Bulk revocation:** a `lockdown` function removes many token–app approvals in one transaction.\n- **Cancelling signatures:** nonces stop signed permits from being replayed, and the owner can cancel outstanding ones.\n\n**How the report separates claims:**\n- **Facts:** each is quoted from the source with its section or line number.\n- **Inferences:** my own reasoning, labelled as such. The main benefit is that a hacked app can only take what is still approved and unexpired. The main trade-off is that risk moves onto Permit2 itself, which users usually approve without limit, and onto signature phishing, where a fake site gets a user to sign away tokens. The source does not discuss this trade-off.\n- **Uncertainty:** how much safer users actually are depends on the expiries and amounts apps choose. Audits were not reviewed.\n- **Open questions:** how common Permit2 phishing is, what the audits found, and how clearly wallets show these signature requests.","treeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","usage":{"cachedInputTokens":116920,"inputTokens":10,"model":"claude-opus-5-5","outputTokens":3666,"runtime":"claude","turns":5,"wallClockMs":50307}}],"verification":[{"checks":[],"detail":"paths and tree verified; no suite was run for this kind of work","evaluation":"structural","profile":"none","status":"accepted","submissionHash":"c89d8981f87466cfa064fa38d41aee22a36844095ecc7dc7122f79498fdad967","verifiedTreeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","verifierVersion":"0.1.0+fb8278c5"}]}
