Audit the whole protocol: every contract in src/, script/DeployMainnet.s.sol, script/DeployPreflight.sol, deploy/mainnet/ and docs/MAINNET-RUNBOOK.md section 7, at the pinned commit, for a mainnet launch. Seventeen audit rounds and their fixes are in (docs/AUDIT-*.md; the chain is web/content/docs/reference/audit-history.md). This is the LAST review before mainnet, of the WHOLE PROTOCOL at the commit that will deploy: every contract in src/, the deployment and the launch runbook, each mechanism in turn. Since the previous sweep (e4baedf, docs/AUDIT-FINAL-SWEEP-3-2026-10-09.md): the paced debt's netting reverted to the transaction's own mint, so the figure errs low, never high; the Treasury's paying functions gained a transient reentrancy guard; comments restated: git diff e4baedf c7d50ee -- src script. ACCEPTED items, each with its bound stated where it lives, are findings only if the stated bound is wrong or the reason does not hold: liquidation at a held-down pool (CDPVault.bite: 1.2/(1-push) of the debt at the real price, from the borrower; a thin position's remainder as bad debt), the payout price's gain per hour of hold and its lag after a rise or an honest fall (PAYOUT_PRICE_FALL_BPS_PER_HOUR), the dip and stale-term read (the paced figures), the paced debt erring low (_tallyPrincipalRetired), the fee-base floor, the work ceiling as an aggregate once the wage is on, the oracle's walk cost (docs/PARAMETERS-2026-10-05.md). Rank severity by what a finding lets someone take or block with the constants as committed (LINE $1M, wage 0, mat 170 at NHI >= 0.85, grace 6 hours, CHOP 20%, the backing's rise 2 points of par an hour, the follow 10% an hour, the payout price's fall 1% an hour, fee floor 100,000, fee cap 5%, FEED_MAX_DEVIATION_BPS 2000, SKEW_BPS 500, TIMELOCK 48 hours). 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. The oracle's feeds read one full-range Uniswap v4 pool on Ethereum, about $2.3M a side with a 1% fee; IMD also trades in other pools and on Base and Robinhood Chain, so a price held off-market in the oracle's pool is open to arbitrage from those venues. docs/PARAMETERS-2026-10-05.md has the numbers every economic parameter was chosen from. Answer each numbered question, including the ones where nothing is wrong: 1. THE ORACLE (SwarmFeed, PriceFeed, SpotFeed, NhiFeed, UsdPriceFeed, SharePriceFeed, SwarmRelay, OracleAsker): attestation checks (signer, domain, question binding, window, replay), the epoch and deviation rules after silence, the first value, Chainlink staleness and failure, the asker's triggers, budget, back-off and callback, relay bundles. Anything that lands a value the question does not support, holds a feed off, or spends the Treasury's budget for nothing. 2. THE VAULT'S BORROWING AND LIQUIDATION (lock, lockIMD, free, draw, wipe, bark, barkFor, heel, bite, cover, the stability fee, dust, bad debt, the debt ceiling): every ordering by one or several positions and the relay; anything that leaves debt unbacked, frees collateral a position needs, stops a liquidation that should happen, or takes more than the stated bounds. 3. REDEMPTION AND THE PACED FIGURES (cash, the paced backing, supply, debt and payout price, resecure, the fee base and ratchet, the reserve route): anything that pays a redeemer more than the honest backing at the paid price, or blocks honest redemptions beyond the stated lags. 4. THE TREASURY (sync, withdraw, payStream, fundOracle, redeemIMD, the reserve register and its valuation, launch fees, the new guard): every exit bounded as documented, bad debt first, nothing an outsider can take, freeze or mis-record. 5. GOVERNANCE AND MINTING FROM WORK (Parameters, the timelock and every bound, Governed, SwarmWorkOracle, WorkOracleFactory, earn, earnLine, backedDebt): anything a governor can do beyond the bounds or faster than 48 hours, and anything that mints work against backing that is not there if the wage is turned on. 6. IMDUSD, THE FACTORIES AND THE DEPLOYMENT (ImdUSD, TreasuryFactory, DeployMainnet.run, verifySeeded, runVault with VAULT_SALT, verify, plan.py, the pinned bodies) and the launch window hour by hour against the runbook: what can be deployed wrong and pass, what a stranger can do between the stages, every way the protocol can halt on day one and how each recovers. 7. REENTRANCY AND EXTERNAL CALLS across every contract: each external call, what it can call back into, and whether state is written before it. 8. Every comment, NatSpec or runbook line that claims a property the code does not have, and the list of what you read in full and what you could not reach. Not findings: addresses in DeploymentConfig that are placeholders until deployment (INTAKE, ORACLE_ASKER, TREASURY_FACTORY, WORK_ORACLE_FACTORY); the mocks (MockIMD, MockWorkOracle, LaunchToken); script/checks/ (a separate, partly stale tree); web/ and points/; anything docs/COMPUTE-BACKING-DESIGN.md describes as future work; and findings of the earlier audits in docs/AUDIT-*.md and docs/INTERNAL-AUDIT-2026-10-04.md, unless the fix regressed. A constant set to a deliberate economic value is not a finding; an arithmetic or ordering error in how it is used is. For every finding: severity; file and function; the call sequence from an external caller; a concrete failing input or state with expected against actual; whether it is reachable with the constants as committed; and the smallest fix. Also report every place a comment or NatSpec claims a property the code does not have, and say which contracts you read in full and which you could not reach.
