Find where this protocol can spend less gas WITHOUT weakening any security property, for a mainnet launch.
Find where this protocol can spend less gas WITHOUT weakening any security property, for a mainnet launch. imdUSD is a dollar-denominated CDP stablecoin borrowed against sIMD (IdentityMD's staked IMD, an ERC-4626 share with 24 decimals, about 7.95 IMD each). Prices come from swarm-attested oracle feeds bound to pinned questions, times Chainlink ETH/USD. Everything about the deployment is in src/DeploymentConfig.sol and docs/MAINNET-RUNBOOK.md: ParameterizedVault is the deployed vault; it creates ImdUSD, Parameters, its Treasury (through TreasuryFactory), UsdPriceFeed and SharePriceFeed in its constructor. One cold governor key (APPROVED_OPERATOR) proposes parameter changes behind a 48-hour timelock. Collateral pricing is per 1e18 raw units throughout. IMD's only market is a full-range Uniswap v4 pool, about $2.3M a side with a 1% fee; docs/PARAMETERS-2026-10-05.md has the numbers every economic parameter was chosen from. Measure first, at the pinned commit: forge build --sizes, forge snapshot, and forge test --gas-report. Then propose savings, ranked by gas saved per typical call times how often the call happens. Hot paths, in rough order of frequency: lock, lockIMD, draw, wipe, free (CDPVault/ParameterizedVault); bark, barkFor, bite, cover; cash; SwarmFeed.submitAttestation through SwarmRelay.relay, relayAndBark, relayAndBite; OracleAsker.arm, ask, askPaid and onOracleResult (which must stay well inside the Intake's 200,000-gas callback stipend); Treasury.fundOracle, payStream, sync. Contract SIZE counts too: ParameterizedVault's runtime is about 20,300 of 24,576 bytes and its initcode about 42,900 of 49,152, so bytes saved there are worth reporting. For EVERY proposal: the file and function; the change, as a diff; gas before and after, measured by applying it to a scratch copy and re-running the suite (state that the full suite still passes); and the security property it could touch and why it still holds. Out of bounds, never propose: removing or loosening a check, guard, bound, freshness or divergence gate; unchecked arithmetic unless the bound is proven in the proposal; dropping nonReentrant; changing an authority, a constant's value, an event or error a keeper or the terminal reads (docs/abi), or the order of external calls. Report gas-neutral simplifications only if they also shrink the vault. Say plainly where the code is already efficient and nothing is worth changing. Write the report to artifacts/gas-review.md: the measured baseline table, the ranked proposals, and what you measured but rejected. Do not modify the repository's tracked files.
