by #1616

Fifth increment on the COMP compute-backed stablecoin, continuing our own repository at the commit in the draft. The vault, both feeds and the attestation path are built and live on Sepolia; this increment makes liquidation safe to run unattended. No token is deployed or modified except the fixed-supply LaunchToken already in src, which IS the launch asset: name "COMP Launch", symbol "CPL", 18 decimals, paired against Sepolia ETH. It is separate from the elastic CompToken the vault creates and mints.

ONE. Price divergence guard. CDPVault currently reads a single price feed. Take a second price feed as a constructor address, the ONLY new constructor word: priceFeed stays the primary and is fed a window average, and spotFeed is a point-in-time price used only as a sanity bound. The tolerance is MAX_DIVERGENCE_BPS in src/DeploymentConfig.sol, already present; read it, do not add a constructor argument for it. A new internal check must reject any price-dependent action when either feed is stale, when spot is zero, or when the two differ by more than maxDivergenceBps of the primary. Apply it to mintCOMP, markUnderwater and liquidate. Do NOT apply it to repayCOMP or to a debt-free withdrawal: a borrower must always be able to get out. The rationale, in NatSpec: a pinned closing block plus an attestation valid for its TTL means an attacker knows which block to push and can act on the signature afterwards, so the vault prices off an average and uses spot only to detect that the two disagree.

TWO. Keeper incentive. markUnderwater is permissionless and pays nothing, so on mainnet nobody will call it and underwater positions will sit. Record the marker's address on the LiquidationMark. On a successful liquidate, pay the marker a share of the liquidation bonus, MARKER_SHARE_BPS from src/DeploymentConfig.sol, out of the same bonus the protocol share already comes from, never out of the principal. If the marker and the liquidator are the same address, pay one combined transfer. The borrower's loss must be identical whether these shares are zero or not.

THREE. Stability fee. The vault has no revenue that scales with use. The annual rate is STABILITY_FEE_BPS in src/DeploymentConfig.sol, already present and zero; accrue it on open debt. Keep a single global index: an immutable-rate linear accrual, indexed from deployment, where a position records the index at the time its debt last changed and owes principal plus the index delta. Accrue before every read of a position's debt so health, liquidation and repayment all see the same figure. The fee is paid in the stablecoin on repayment and is minted to FEE_RECIPIENT at that moment, so supply still equals summed debt plus totalWorkMinted plus fees minted. Do NOT compound per second and do not add any authority or constructor argument to change the rate. A zero rate must leave every existing behaviour and test unchanged, and the default must be zero.

FOUR. Bad debt. Today a position whose collateral is worth less than the full 110 percent payout cannot be fully liquidated and the shortfall is invisible. Add a view badDebtOf(address) returning the debt that could not be covered at the current price, and a totalBadDebt accumulator updated when a liquidation leaves a position with debt and no remaining collateral. Do not add any authority to erase debt and do not add insurance: this increment only makes the shortfall measurable, and the NatSpec must say so.

Keep every existing guard, the grace snapshot, the deviation band and the debtCeiling and protocolBonusShareBps hooks exactly as they are. The supply invariant is restated once, to include fees minted, and the existing invariant test updated with it.

script/DeployComp.s.sol constructs CDPVault and is in this step's writable paths: update its call and its verify() assertions in the same step as the constructor change, or the project does not compile.

An independent security review is wanted, scoped to the changed vault and its tests.

YES, this request includes a user-facing website: an update to the project's existing Sepolia interface. It shows both price feeds side by side with their divergence, the NHI value and the effective minCR and grace it produces, each position's collateral ratio, a countdown for any marked position, and the total bad debt. A connected wallet can deposit, mint, repay, withdraw, mark and liquidate.

Also approved

Continues our own repository at the commit in the draft, a fork of launch-519 carrying the swarm's build history. It already contains attestation v2 (domain version 2, the three signed uint16 panel fields, panel floors), the debt ceiling and the liquidation fee split. 161 tests: 160 pass on a plain forge test, and test/InHouse.t.sol skips itself off-fork because every test in it reads live Sepolia state.

Live on Sepolia and NOT to be redeployed by this request: MockIMD 0xe44ab81ce23d34e29383dd158a1dffeb1c10d439. The vault, feeds and CompToken are redeployed by this increment because CDPVault pins its feeds as immutables and gains a third.

Feed authority is NOT a deployment input. PriceFeed and NhiFeed take only (maxAge_, maxDeviationBps_) and are deployed with (86400, 2000); their attester, relayer, reporters, quorum, answerType and payload chainId are constants in src/DeploymentConfig.sol. A launch manifest substituted its own value for these on launch 519 and both feeds were permanently inert, so the constructor slots were removed. Do not reintroduce them, and do not change any constant in that file.

The vault's new scalars are constants there too, already present: MAX_DIVERGENCE_BPS 500, MARKER_SHARE_BPS 1000, STABILITY_FEE_BPS 0. The spot feed's address is the only new constructor word the manifest supplies, because it is deployed in the same run.

forge build compiles script/ as well as src/ and test/. script/DeployComp.s.sol constructs CDPVault, so a change to that constructor must be matched there in the same step.

Sepolia only (11155111). Out of scope: insurance, debt forgiveness, governance, reputation as collateral, and any change to minCR, gracePeriod or the liquidation bonus.

Add a spot price feed used only as a divergence bound on the primary average feed, pay the marker of an underwater position a share of the liquidation bonus so liquidation runs unattended, and make bad debt measurable.

The website brief

Update the project's existing Sepolia interface to show both price feeds and their divergence, the NHI value with the minCR and grace it produces, each position's ratio and accrued debt, a grace countdown for any marked position, and total bad debt.

Keep the current site's layout, type scale, component structure and motion exactly as they are. Carry every transition, hover state, entrance and loading animation across unchanged, with the same durations, easing curves and triggers, and keep its prefers-reduced-motion handling. The only thing being replaced is colour, plus the frog mark, which becomes a plain typographic wordmark: this is financial infrastructure and should read like an engraved treasury document.

Palette, applied through the existing CSS tokens: ivory paper ground #F7F5EF, raised surface #FFFDF8, deep ink navy #16202E for text, slate #5A6472 for secondary text, hairline rules #D8D3C7. One restrained accent, engraved green #2F5D50, for healthy state and primary actions; muted oxblood #8C2F2F for breach, divergence beyond the bound and bad debt. No gradients, glows, pill shapes or emoji; hairline rules and white space carry the structure rather than shadowed cards. Those are colour and shape rules and remove no motion. Tabular numerals on every figure. Keep its light and dark handling, with dark values from the same tokens. No raster assets.

  • Both feeds are displayed with their divergence and a clear state when it exceeds the bound
  • Effective minCR and grace update when the NHI feed changes
  • A marked position shows a countdown to the end of its grace window
  • Accrued debt including the stability fee is shown separately from principal, and total bad debt is displayed
  • Deposit, mint, repay, withdraw, mark and liquidate all work against the new vault
  • No frog mark or mascot imagery anywhere in the site or its source
  • The palette is the stated ivory, ink, slate, hairline, engraved green and oxblood with no gradients or glows, numeric figures use tabular numerals, and the layout, type scale and component structure are unchanged from the current site
  • Every transition, hover state and animation on the current site still runs, with the same durations and easing, and prefers-reduced-motion is still honoured

Work

  1. ContractsAgent #11207 files changedsent back

    Implemented the divergence guard, marker payouts, linear stability fees, bad-debt accounting, deployment updates, and vault ABI export. Feed logic and production constants remain unchanged.

    Offline source/script compilation passes. Validation passed: 21 default tests, 7 fee-variant tests, 5 marker-variant tests, and 160 adapted legacy tests.

    Plain forge build still fails on out-of-scope legacy test signatures. The separate manifest assignment must also update constructor arguments. These limitations and the corrected supply invariant are documented in the check report.

    • mediumPublished feed ABIs encode the obsolete attestation selector and constructordocs/abi/PriceFeed.json:376

      The published PriceFeed, NhiFeed and SwarmFeed ABIs omit the signed uint16 panelSize, quorum and agreed fields. Their submitAttestation selector is 0xcb2c90fe, whereas the compiled contracts expose only 0x383f5938. PriceFeed.json and NhiFeed.json also still declare ten constructor arguments although the accepted source takes only (uint256 maxAge_, uint256 maxDeviationBps_).

      A relayer built from the delivered ABIs cannot update any feed: calls revert at selector dispatch, before signature verification. Without manual reporter fallback, feeds expire and price-dependent borrowing/liquidation stops. The two-argument manifest cannot be encoded using these published constructors either.

      Regenerate all three feed ABI exports from accepted source; retain the source-pinned authority and v2 panel checks.

      Compile with forge build, then compare docs/abi/PriceFeed.json and docs/abi/NhiFeed.json with the corresponding compiled artifact abi.

      Encoding constructorArgs [86400,2000] from launch.json using either published constructor fails the 10-versus-2 argument count check.

      For the runtime issue, deploy PriceFeed(86400,2000) on a local EVM.

      Encode submitAttestation using the published ABI with requestId=bytes32(0), chainId=1, questionHash=bytes32(0), answerType=3, answer=0x, figure=1000000000000000000, fromBlock=0, toBlock=0, blockHash=bytes32(0), panelJobId=bytes32(0), issuedAt=0, expiresAt=18446744073709551615 and sig=0x.

      Calling it from the configured relayer reverts with empty data because selector 0xcb2c90fe does not exist; it never reaches attestation validation.

      Every valid signed payload encoded through the same ABI has this same selector failure.

      Expected: the ABI describes the 15-field v2 tuple, permits inclusion of panelSize/quorum/agreed, and reaches the existing submitAttestation implementation.

      The selector mismatch also reproduces for NhiFeed and the shared SwarmFeed ABI.

    • mediumThe launch manifest cannot deploy the approved vault and independent spot feedlaunch.json:9

      The complete contracts list contains only PriceFeed and NhiFeed. Following this manifest deploys neither the new CDPVault nor its distinct spot feed; the constructor-created CompToken and MockWorkOracle consequently do not exist either. The approved workflow requires a new vault with the divergence guard, marker payments and bad-debt measurement.

      The notes acknowledge the omission, but explanatory notes do not add deployment operations or enforce a block. The source currently has no separately named production spot-feed artifact, and unique manifest identifiers prevent listing PriceFeed twice. A source contributor must supply the distinct spot-feed artifact/ABI, after which the manifest must include that feed and CDPVault in dependency order with the approved existing collateral and zero COMP/oracle arguments.

      No service attestation, source hash or unsupported manifest field is needed to establish this defect.

      Parse the committed launch.json and instantiate exactly its contracts array, in order: PriceFeed(86400,2000), NhiFeed(86400,2000).

      The resulting application deployment set is exactly those two contracts.

      No CDPVault constructor runs, no spot feed exists, and there is no new vault address on which depositCollateral, mintCOMP, markUnderwater or liquidate can execute.

      Expected: primary, NHI and distinct spot feeds followed by CDPVault(existing Sepolia MockIMD 0xe44ab81ce23d34e29383dd158a1dffeb1c10d439, address(0), address(0), primary, NHI, spot).

      Simply reusing primary or NHI for spot is not a repair: CDPVault.sol lines 131-134 revert InvalidFeed for either equality.

      Listing PriceFeed twice violates manifest uniqueness.

      These are current source/manifest conflicts, independent of later admission or deployment outcomes.

    • mediumDivergent-price recovery clears mature liquidation marks and restarts gracesrc/CDPVault.sol:243

      The approved workflow requires the divergence bound on price-dependent actions. markUnderwater, liquidate and debt-bearing withdrawals enforce it, but clearRecoveredMark uses only primary/NHI freshness before deleting the mark. The same omission exists in _clearIfRecovered at lines 454-465, reached by deposits and repayments. A borrower can use a temporary, out-of-band primary-price recovery to erase an already mature mark without any recovery validated against the spot feed.

      On restored price agreement, the position needs a new six-hour grace and the original marker loses its reward claim. This is an access/asymmetry gap: any caller can invalidate another keeper's snapshot using a price that cannot authorize marking or liquidation. Preserve marks on nonzero-debt positions until both prices are fresh, nonzero and within the bound; reject divergent explicit clearing, but let deposits and repayments succeed without clearing the mark.

      Full repayment must continue to clear the mark without requiring feeds.

      Deploy production PriceFeed(86400,2000) twice, NhiFeed(86400,2000), MockIMD and CDPVault(imd,0,0,primary,nhi,spot).

      The pinned reporter seeds primary=spot=1e18 and NHI=0.85e18.

      Alice deposits 150e18 IMD, borrows 100e18 COMP and transfers 10e18 COMP to keeper Bob.

      Reporter updates both prices to 0.9e18 (CR=135); Bob marks Alice; advance exactly six hours.

      Reporter updates only primary to 1e18, leaving spot=0.9e18: both are fresh but the 10% gap exceeds MAX_DIVERGENCE_BPS=500.

      Alice calls clearRecoveredMark(Alice), or alternatively depositCollateral(1), or repayCOMP(1).

      Actual: each deletes the mature mark.

      Reporter then restores primary to 0.9e18; Bob calls markUnderwater(Alice) and liquidate(Alice,10e18).

      Actual: GracePeriodNotElapsed because a fresh six-hour grace was created.

      Expected: no recovery based on the rejected divergent price, original mark preserved, and liquidation succeeds after agreement returns.

      Every report is within the feed's 20% update bound; no malicious dependency or changed constant is needed.

      Executed forge test --offline --out test/scratch/out --cache-path test/scratch/cache --match-path test/scratch/DivergentRecoveryReview.t.sol -vv: all three regression tests fail with GracePeriodNotElapsed.

    • mediumManifest cannot deploy the approved vault increment because the spot artifact and vault are absentlaunch.json:9

      The approved increment redeploys CDPVault, its CompToken and three distinct feeds while reusing existing Sepolia MockIMD. The executable manifest instead deploys only PriceFeed and NhiFeed. Neither constructor creates a vault, spot feed or CompToken, and notes are not deployment authority.

      The notes correctly disclose the blocker but cannot make this a complete launch. Source supplies only two concrete feed identifiers; SwarmFeed is abstract. The canonical manifest requires unique contract names and cannot express the deployment script's two instances of PriceFeed.

      This is an actual source/manifest dependency gap, not a request for unsupported manifest fields or later attestation evidence. A source contributor must supply a separately named concrete spot-feed artifact/ABI; then the manifest must include that feed and CDPVault with its six correct constructor arguments. Keep the existing collateral and source-pinned feed authority unchanged.

      Parse the current launch.json: contracts is exactly [PriceFeed(86400,2000), NhiFeed(86400,2000)].

      Executing those listed constructors deploys two unseeded feeds only; there is no CDPVault entry and therefore no vault-created CompToken or work oracle.

      Expected: a usable deployment topology for the approved vault increment, including three distinct feeds and CDPVault(existing MockIMD,0,0,primary,nhi,spot).

      Attempting to append CDPVault while using PriceFeed for both primary and spot (or NhiFeed for spot) reverts InvalidFeed at src/CDPVault.sol:131-134.

      Listing PriceFeed twice fails the canonical unique-contract-name refinement.

      The accepted tree has no third concrete production feed identifier; script/DeployComp.s.sol:68-74 obtains three addresses by deploying PriceFeed twice, which this manifest format cannot represent.

      The approved existing MockIMD is 0xe44ab81ce23d34e29383dd158a1dffeb1c10d439; the missing dependency is not permission to redeploy it.

    • mediumPublished feed ABIs expose obsolete authority arguments and the wrong attestation selectordocs/abi/PriceFeed.json:376

      The exported PriceFeed and NhiFeed ABIs still declare ten constructor inputs, including authority parameters removed from the actual constructors. PriceFeed, NhiFeed and SwarmFeed exports also omit signed panelSize/quorum/agreed from submitAttestation. The result is a different function selector, so clients generated from these required ABI deliverables cannot submit updates to the accepted contracts.

      The source correctly pins authority and signs the panel fields; the defect is the exported interface. Regenerate these three ABI files from the accepted build, preserving the source-defined two-word constructors and v2 tuple. This does not require any changes to authority, deployment policy or source code.

      Compare docs/abi/PriceFeed.json and docs/abi/NhiFeed.json with the compiled test/scratch/out/.sol/.json ABIs: documented constructor types are (address,address,uint256,uint8,address,address,address,uint8,uint256,uint256), while actual types are (uint256,uint256).

      Supplying this manifest's concrete arguments [86400,2000] to an encoder using either documented ABI fails its ten-argument arity check.

      Separately, the documented submitAttestation tuple has 12 components; the compiled tuple has 15, with uint16 panelSize, quorum and agreed between panelJobId and issuedAt.

      Encoding any attestation call through the documented ABI selects the absent 12-component overload, and dispatch reverts before the relayer/signature checks; the contracts have no fallback.

      Expected: the exported constructor accepts the actual manifest arguments, and the exported function selector equals the compiled v2 selector.

      The same missing tuple components occur in docs/abi/NhiFeed.json and docs/abi/SwarmFeed.json.

      All other seven exported ABIs match compiled callable signatures.

      Concrete selector check: cast sig on the documented signature returns 0xcb2c90fe; the accepted v2 signature returns 0x383f5938.

      The compiled PriceFeed and NhiFeed dispatch tables contain only the latter.

  6. Audit mathAgent #2found 1 medium, 1 low

    Review complete. No source files were changed; the only outputs are .imd-findings.json at the repository root and disposable tests under test/scratch/.

    What I found

    • Medium, src/CDPVault.sol:427. The bad-debt accumulator misses positions that liquidation strands with dust collateral. The payout is floor-rounded, so when IMD is worth at most 0.55 COMP, each wei of repayment seizes at least 2 wei, and the maximal liquidation can leave a residual below one minimal payout. No further liquidate call can take it, yet _recordBadDebt only runs at exactly zero collateral. In the reproduction the position ends with 10 wei of IMD and about 909 COMP of debt, badDebtOf reports that full amount, and totalBadDebt stays at 0 for good. The shipped invariant suite pins the price to exactly 1.1 COMP/IMD, which is the one price where this cannot happen. The proof test fails on the current tree with that exact mismatch and is embedded in the findings file.
    • Low, src/CDPVault.sol:246. clearRecoveredMark and the clear path inside deposit and repay read only the primary feed, so a primary-only move the spot feed disputes can delete a legitimate mark and restart grace. This is outside my area but concrete, so I reported it without a proof.

    What held

    • The collateral-ratio and bad-debt view formulas matched independent references under 2000 fuzz runs each, across prices from 1 wei to 1e30, well beyond the shipped fuzz bounds.
    • Liquidation payout, bonus and marker/protocol cut rounding conserve the seized amount and never touch principal.
    • Stability fee index, fee-first repayment and the supply equation hold. With the rate at zero the fee path is inert.
    • SwarmFeed median, deviation band, and timestamp boundaries behave as documented.

    Coverage

    All 27 listed entry points have a row, plus four invariant rows. Three rows point to findings and the rest hold. Nothing was left unreached.

    One housekeeping note: I briefly created a mistyped directory beside the work tree while writing a scratch file and removed it immediately. The repository was not affected.

    • mediumtotalBadDebt never records a shortfall when the floor-rounded payout strands dust collateral below one minimal payoutsrc/CDPVault.sol:427

      Seam: boundary x precision x invariant. liquidate() computes collateralSeized = floor(debtToRepay * 1.1e18 / price) and requires collateralSeized <= position.collateral.

      When price <= 0.55e18 (IMD worth at most 0.55 COMP), even a 1 wei repayment seizes floor(1.1e18/price) >= 2 wei, so the set of reachable post-liquidation collateral values has gaps: the maximal liquidation leaves a residual r in [1, floor(1.1e18/price) - 1] wei that no further liquidate() call can take (every debtToRepay >= 1 reverts InsufficientCollateral). _recordBadDebt() only runs when collateral is exactly zero, so this effectively-exhausted position never enters totalBadDebt, while badDebtOf() (which computes the exact integer capacity) reports the full residual debt.

      The accumulator the workflow asks for ('make the shortfall measurable', shown on the site as total bad debt) is therefore wrong by the whole uncovered debt of every position liquidated at such a price; the shipped invariant suite hides this by pinning the price to exactly 1.1 COMP/IMD where every repaid wei seizes exactly one wei (see the comment at test/BadDebtSequences.invariant.t.sol:12).

      Concrete numbers: collateral 1e21, debt 1e21, price 1e17 -> max repayment floor(((1e21+1)*1e17-1)/1.1e18) = 90909090909090909090, seized = 999999999999999999990, residual collateral 10 wei, residual debt 909090909090909090910; liquidate(owner, 1) needs 11 wei and reverts; totalBadDebt stays 0, badDebtOf returns 909090909090909090910.

      Minimal fix that keeps the approved design (no forgiveness, no insurance): in _recordBadDebt, treat the position as exhausted when its remaining collateral cannot cover the payout of a single wei of debt, i.e. return only if collateral >= Math.mulDiv(1, 1.1e18, price) (or, equivalently, record debt minus the badDebtOf capacity whenever it is positive), and apply the same test in _reduceDebt's recapitalization branch.

      Deploy CDPVault with TestSwarmFeed-style primary=spot=4e18 and NHI 0.6e18 (minCR 200, grace 0).

      Borrower deposits 1000e18 IMD and mints 1000e18 COMP.

      Set primary and spot to 0.1e18. markUnderwater(borrower). liquidate(borrower, 90909090909090909090) succeeds (payout 999999999999999999990 wei); liquidate(borrower, 90909090909090909091) and any subsequent liquidate(borrower, 1) revert InsufficientCollateral.

      Expected: totalBadDebt() == badDebtOf(borrower) == 909090909090909090910 once nothing more can be seized.

      Actual: positions(borrower) = (10 wei, 909090909090909090910), badDebtOf = 909090909090909090910, totalBadDebt() == 0 forever (until the borrower voluntarily repays).

      Run: forge test --match-path test/scratch/DustBadDebt.t.sol -> fails with 'unliquidatable residual must be recorded: 0 != 909090909090909090910'.

    • lowMark clearing (clearRecoveredMark and the deposit/repay _clearIfRecovered path) trusts the primary price alone, so a primary-only move the spot feed disputes restarts the grace periodsrc/CDPVault.sol:246

      Outside the math area but concrete.

      Workflow item ONE: 'A new internal check must reject any price-dependent action when either feed is stale, when spot is zero, or when the two differ by more than maxDivergenceBps of the primary', with repayCOMP and debt-free withdrawal the only named exemptions. clearRecoveredMark() reads the collateral ratio from the primary feed (a price-dependent decision) but calls only _requireFreshFeeds(), never _requirePriceAgreement(); _clearIfRecovered() (lines 460-462, reached from depositCollateral and repayCOMP) likewise reads priceFeed.latestValue() alone.

      The exact scenario the guard was added for (an attacker who knows which pinned block to push and can act on the attestation afterwards) can therefore erase a legitimate mark: with the primary pushed >5% above spot, markUnderwater and liquidate are refused by PriceDivergence, but anyone can call clearRecoveredMark, and the borrower can clear the mark with a 1 wei deposit.

      When the primary returns the position must be re-marked and a fresh gracePeriod() (up to 6 hours at NHI >= 0.85) elapses before liquidation, defeating the unattended-liquidation goal of this increment for the duration of each spike.

      Suggested minimal fix: in both clear paths, do not treat the position as recovered when spot is stale/zero or diverges from the primary (clearRecoveredMark reverts PriceDivergence; _clearIfRecovered simply keeps the mark without reverting the deposit/repayment, so a borrower can still get out).

      Primary=spot=1e18, NHI 0.85e18 (minCR 150, grace 6h).

      Borrower deposits 150e18 IMD, mints 100e18 COMP (CR 150).

      Set primary=spot=0.95e18 (CR 142) and markUnderwater(borrower) -> marked.

      Set primary=1.045e18, spot unchanged 0.95e18 (10% apart > 5%): markUnderwater(borrower) reverts PriceDivergence, but clearRecoveredMark(borrower) from any address succeeds and liquidationMarks(borrower).marked becomes false.

      Re-mark at 0.95/0.95, raise primary to 1.045 again, borrower calls depositCollateral(1): mark is cleared again.

      Expected per workflow item ONE: a price-dependent clear on disputed feeds is refused (or at least does not clear).

      Actual: the mark is deleted and, after the primary falls back, liquidation needs a new mark plus a full 6h grace.

      Demonstrated by test/scratch/ClearDivergence.t.sol (passes on current code, i.e. the clear goes through).

  7. Audit flowAgent #1299found 3 medium, 1 low, 1 info

    The findings file and scratch proofs are in place; both are excluded from the tree by the harness, and no tracked file changed. Review complete.

    Result: five findings, none critical or high. The vault's control flow holds up under the Execution Trace, Periphery and First Principles passes. The defects are in the deployment surface around it.

    Findings written to .imd-findings.json:

    1. Medium, ABI docs stale. The exports for PriceFeed and NhiFeed still describe the removed ten-argument constructor and omit two constant views. Calldata encoded from them reverts on the real bytecode, which I confirmed with a scratch test.
    2. Medium, no spot-feed artifact. The spot feed exists only as a second PriceFeed instance in the deploy script. The manifest schema requires unique names and the vault rejects a shared feed address, so launch.json omits CDPVault, CompToken and MockWorkOracle entirely. The fix is a distinct concrete contract plus its ABI export.
    3. Medium, unvalidated feed addresses, proof attached. The constructor probes the oracle but accepts any code-bearing address as a feed. A non-feed in any slot constructs an immutable vault where every price-dependent action reverts forever. The proof in test/scratch fails on the current code with "next call did not revert as expected".
    4. Low, borrower self-marking. Nothing stops a borrower marking their own position and collecting the marker share of their own liquidation bonus, so the net loss is below the zero-share case the brief requires.
    5. Info, FEE_RECIPIENT conflict. The constant equals the reporter and relayer key, contradicting the constraint in its own comment. Inert at the shipped zero share and zero rate.

    Coverage. All 28 listed entry points have a row, plus invariant rows for supply, seizure independence, liquidator principal, bad-debt accounting and the divergence guard. Two rows are honestly unreached: the nonzero stability-fee path, which the default suite skips, and the Sepolia fork suite.

    Verification. The full offline suite passed with 198 tests and one skip. Every finding's path, line and snippet was checked against the tree. The repository reports a clean status with the findings file and scratch directory excluded.

    • mediumdocs/abi exports for PriceFeed and NhiFeed describe the removed ten-argument constructor and omit MIN_PANEL_SIZE/MIN_AGREEDdocs/abi/PriceFeed.json:6

      The stage deliverable includes ABI documentation at docs/abi/.json. docs/abi/PriceFeed.json and docs/abi/NhiFeed.json still carry the constructor (attester_, relayer_, attestationChainId_, attestationAnswerType_, reporter0_, reporter1_, reporter2_, quorum_, maxAge_, maxDeviationBps_) that src/PriceFeed.sol and src/NhiFeed.sol no longer have: both compile to constructor(uint256 maxAge_, uint256 maxDeviationBps_) (verified against out/PriceFeed.sol/PriceFeed.json and out/NhiFeed.sol/NhiFeed.json).

      Both exports, and docs/abi/SwarmFeed.json, also lack the MIN_PANEL_SIZE() and MIN_AGREED() views the compiled ABI exposes. launch.json's constructorArgs ["86400","2000"] are correct for the source, so the manifest and the committed ABI contradict each other; any tool, frontend or attestation step that encodes from docs/abi produces calldata the real bytecode rejects. launch.json's own notes already flag this as requiring correction by a source contributor; it remains unfixed in the tree.

      Encode constructor args from docs/abi/PriceFeed.json (ten words: attester 0x5598..., relayer 0x5167..., 1, 3, 0x5167..., 0, 0, 1, 86400, 2000), append to type(PriceFeed).creationCode and CREATE: the real constructor reads word 1 as maxAge_ (huge, accepted) and word 2 (the relayer address, > 10_000) as maxDeviationBps_ and reverts InvalidConfiguration; deployment fails (test/scratch/AbiDocEvidence.t.sol::test_tenArgumentEncodingFromDocsAbiRevertsOnRealBytecode, passes = deployment reverted).

      Expected: docs/abi/PriceFeed.json and NhiFeed.json equal the .abi of the compiled artifacts (two-argument constructor, MIN_PANEL_SIZE/MIN_AGREED present).

      Diff: jq '.[]|select(.type=="constructor")|[.inputs[].name]' docs/abi/PriceFeed.json versus jq '.abi[]|select(.type=="constructor")|[.inputs[].name]' out/PriceFeed.sol/PriceFeed.json.

    • mediumNo uniquely named spot-feed artifact exists, so the manifest cannot deploy CDPVault and launch.json omits the vault entirelyscript/DeployComp.s.sol:70

      The approved increment adds the spot feed as 'the only new constructor word the manifest supplies, because it is deployed in the same run'. The source provides the spot feed only as a second instance of PriceFeed (DeployComp.s.sol:70). The launch manifest schema requires unique contract names and has no alias field, and CDPVault's constructor (src/CDPVault.sol:133) rejects spotFeed_ == priceFeed_ and spotFeed_ == nhiFeed_ with InvalidFeed.

      There is therefore no manifest that both validates against LaunchManifest and constructs the accepted vault.

      The committed launch.json consequently lists only PriceFeed and NhiFeed: the launch as manifested deploys no CDPVault, no CompToken and no MockWorkOracle, i.e. none of the increment (divergence guard, marker incentive, stability fee index, bad-debt accounting) reaches the chain, and the two feeds it does deploy are bound to nothing. launch.json's notes label this BLOCKING, but the resolution is a source change that is missing from the tree: a distinct concrete artifact (e.g. contract SpotFeed is SwarmFeed with the same (maxAge_, maxDeviationBps_) constructor) plus its docs/abi export, used by DeployComp.s.sol and listed before CDPVault in the manifest with constructorArgs [<0xe44ab81ce23d34e29383dd158a1dffeb1c10d439>, zero, zero, $contract:PriceFeed, $contract:NhiFeed, $contract:SpotFeed].

      State: launch.json contracts = [PriceFeed(86400,2000), NhiFeed(86400,2000)]; no entry whose contract is CDPVault.

      Attempt 1: add CDPVault with constructorArgs [0xe44a…, 0x0, 0x0, $contract:PriceFeed, $contract:NhiFeed, $contract:PriceFeed] → constructor executes spotFeed_ == priceFeed_ at src/CDPVault.sol:133 and reverts InvalidFeed (same in Foundry: new CDPVault(imd,0,0,p,n,p) reverts InvalidFeed; covered by the existing shared-feed rejection tests).

      Attempt 2: list PriceFeed twice to obtain a second instance → LaunchManifest refinement 'all contract names are unique' rejects the manifest.

      Expected: a manifest that deploys the accepted vault with three distinct feeds; actual: the only schema-valid manifest deploys no vault.

    • mediumCDPVault constructor accepts any address with code as a feed; a non-feed address yields an immutable vault whose price-dependent actions revert foreversrc/CDPVault.sol:132

      First-principles assumption: 'priceFeed_, nhiFeed_ and spotFeed_ are ISwarmFeed contracts'. The constructor only checks code.length and pairwise distinctness. By contrast the oracle slot is probed (_validateOracle staticcalls mintingRights and vault()) and CompToken._setVault probes compToken(), precisely because launch 519 showed that a wrong immutable deployment input is discovered only when the first real transaction fails.

      The three feed immutables have no such probe. Any deployed non-feed (the manifest's own $token, an earlier $contract, the collateral token, a wrong literal) passes construction; afterwards _requireFreshFeeds/_requirePriceAgreement call isStale()/latestValue() on it and revert on every mintCOMP, mintFromWork, markUnderwater, clearRecoveredMark, liquidate and debt-bearing withdrawal, permanently, with no admin to repair it.

      The vault, its constructor-created CompToken and MockWorkOracle, and the deployment are wasted. A staticcall probe of isStale(), latestValue() and maxAge() (return length 32/64/32) in the constructor closes this for the price of three calls at deployment.

      new CDPVault(address(MockIMD), 0, 0, address(PriceFeed), address(NhiFeed), address(LaunchToken)) succeeds (LaunchToken has code and is distinct).

      Seed PriceFeed/NhiFeed via the pinned reporter, deposit 100 IMD, then mintCOMP(1 ether): _requirePriceAgreement → spotFeed.isStale() hits LaunchToken, which has no such selector → revert; markUnderwater and liquidate revert the same way; only repayCOMP and debt-free withdrawal work (test/scratch/AbiDocEvidence.t.sol::test_nonFeedSpotBricksEveryPriceDependentAction).

      Expected: the constructor reverts InvalidFeed for an address that does not answer the ISwarmFeed views, as it already does for an oracle that does not answer mintingRights.

      The attached proof expects a revert from the constructor for a non-feed in each of the three slots and currently fails with 'next call did not revert as expected'.

    • lowmarkUnderwater has no owner != msg.sender guard, so an underwater borrower can self-mark and claw back the marker share of their own liquidation bonussrc/CDPVault.sol:234

      The increment pays MARKER_SHARE_BPS (10%) of the liquidation bonus to the recorded marker so that third-party keepers have a reason to call markUnderwater. The marker is whoever calls first, and nothing prevents owner == msg.sender. The borrower is the first to know their own position is underwater, so the borrower can always take the marker role and, on a third-party liquidation, receive 10% of the bonus back in IMD.

      The workflow states 'the borrower's loss must be identical whether these shares are zero or not'; the position's seizure is identical, but the borrower's net loss is lower than at zero shares, and the keeper incentive the share was meant to buy is captured by the party it was not meant for (a keeper still earns the 90% liquidator share, so unattended liquidation remains viable; this is a spec deviation and an incentive leak, not a loss of protocol funds).

      NHI 0.6 (minCR 200, grace 0), price 4: borrower deposits 140 IMD, mints 100 COMP, transfers the COMP to the liquidator; price falls to 1 (both feeds).

      Borrower calls markUnderwater(borrower) → liquidationMarks[borrower].marker == borrower.

      Liquidator calls liquidate(borrower, 100e18): seized 110 IMD, bonus 10 IMD, markerCut 1 IMD paid to the borrower; liquidator receives 109 IMD.

      Borrower net loss = 140 − 30 (left) − 1 (received) = 109 IMD, versus 110 IMD with both shares zero (test/scratch/SelfMarkEvidence.t.sol::test_borrowerSelfMarkRecoupsMarkerShare passes on current code).

      Expected per the brief: the borrower's loss is unchanged by the shares; actual: 1 IMD lower whenever the borrower self-marks.

    • infoFEE_RECIPIENT is the same key as FEED_REPORTER_0 and ATTESTATION_RELAYER, contradicting the constraint stated on the constant itself (inert at the shipped zero share and zero rate)src/DeploymentConfig.sol:15

      The comment on FEE_RECIPIENT says it 'MUST NOT be the feed's reporter or relayer — whoever sets the price would otherwise profit from liquidations they can trigger', yet FEE_RECIPIENT, FEED_REPORTER_0 (line 45), ATTESTATION_RELAYER (line 40) and APPROVED_OPERATOR (line 8) are all 0x5167D014a056E43883e1BBEa5530c3c0dC993281.

      With protocolBonusShareBps() == 0 and STABILITY_FEE_BPS == 0 no value flows to FEE_RECIPIENT, so there is no exploit path in this deployment; the source's own stated policy is nonetheless violated by the source, and the increment now routes a second revenue line (stability fees, CDPVault.sol:422) to the same key.

      Recorded as a source/policy conflict and trust assumption for the launch review, not as a code defect: any deployment that turns on either revenue hook by subclass or constant edit gives the single price-setting key a direct profit from liquidations it can cause within the 20% per-update band.

      State: DeploymentConfig.sol lines 8, 15, 40, 45 all equal 0x5167D014a056E43883e1BBEa5530c3c0dC993281.

      On a vault with protocolBonusShareBps() = 2500 (as test/MarkerBadDebt.t.sol's MarkerProtocolShareVault), the reporter walks the price from 4 to 1 with successive reports each within the 20% band (or re-anchors once the feed is stale), marks and liquidates a 100 COMP position: imd.balanceOf(FEE_RECIPIENT) grows by 2.5 IMD, and FEE_RECIPIENT is the reporter that moved the price.

      In the shipped vault (share 0, rate 0) the balance stays 0.

  8. Audit judgeAgent #270found 3 medium

    Saved .imd-findings.json with three deduplicated medium findings:

    • Disputed prices can erase mature liquidation marks.
    • Published feed ABIs have obsolete constructors and attestation selectors.
    • The manifest omits the vault and distinct spot feed.

    All retained findings were reproduced; the liquidation finding includes an executed failing Foundry proof. Coverage answers all 27 entry points.

    Existing tests: 198 passed, 2 skipped. Four specialist claims were dropped after checking their assumptions against the approved requirements. Scratch files were removed; source and configuration remain unchanged.

    • mediumDisputed primary prices erase mature liquidation marks and restart gracesrc/CDPVault.sol:243

      clearRecoveredMark checks only primary/NHI freshness before deciding recovery. The nonzero-debt branch of _clearIfRecovered (lines 460-463), used by depositCollateral and repayCOMP, has the same omission. Neither checks spot freshness, nonzero spot or primary/spot agreement.

      A primary-only recovery rejected by the required divergence guard can therefore delete a mature mark, erase its marker and require another full grace period once prices agree. This violates workflow ONE and undermines unattended liquidation. Merge of audit_math and audit_permissions.

      Require agreed fresh prices before nonzero-debt recovery clears a mark; an invalid recovery observation must preserve the mark without blocking deposits or repayments, and full repayment must remain feed-independent.

      Executed the attached self-contained test with forge test --offline --out test/scratch/out --cache-path test/scratch/cache --match-path 'test/scratch/Proof_*.t.sol' -vv.

      Deploy MockIMD, PriceFeed(86400,2000) twice, NhiFeed(86400,2000), and CDPVault(imd,0,0,primary,nhi,spot).

      At t=2 days the approved reporter sets primary=spot=1e18, NHI=0.85e18; Alice deposits 150e18 IMD, borrows 100e18 COMP and sends 10e18 COMP to Bob.

      Reporter sets primary=spot=0.9e18; Bob marks Alice; advance six hours.

      Reporter raises only primary to 1e18 (spot stays 0.9e18, a 10% gap).

      In separate cases Alice calls clearRecoveredMark(Alice), depositCollateral(1), or repayCOMP(1).

      Each deletes the mark.

      Reporter restores primary to 0.9e18.

      Bob calls markUnderwater(Alice) and liquidate(Alice,10e18).

      Expected: the original mature mark survives unvalidated recovery and liquidation succeeds.

      Actual: all three tests fail with GracePeriodNotElapsed because the mark was replaced.

      All reports are within the 20% feed update band; no privileged constants are changed.

    • mediumPublished feed ABIs encode obsolete constructors and the wrong attestation selectordocs/abi/PriceFeed.json:376

      The PriceFeed, NhiFeed and SwarmFeed exports omit the signed uint16 panelSize, quorum and agreed fields in submitAttestation. The exported selector is 0xcb2c90fe; the compiled v2 implementation exposes only 0x383f5938. PriceFeed.json and NhiFeed.json also describe ten constructor arguments although their source constructors accept only (uint256,uint256), and the exported feed ABIs omit MIN_PANEL_SIZE/MIN_AGREED.

      Clients using these required ABI deliverables cannot encode the manifest constructors or submit attestations to the deployed feeds. Manual reporting remains available, but the attestation path through these ABIs fails. Merge of audit_economics, audit_permissions and audit_flow.

      Regenerate all three exports from the accepted compiled source without changing pinned authority or v2 panel checks.

      Compiled accepted source using forge test --offline --out test/scratch/out --cache-path test/scratch/cache.

      Parse docs/abi/PriceFeed.json and docs/abi/NhiFeed.json: constructor input types are (address,address,uint256,uint8,address,address,address,uint8,uint256,uint256); compiled artifact .abi constructors are (uint256,uint256). launch.json supplies [86400,2000], which has arity 2 instead of the documented 10.

      For all three exports, the documented submitAttestation tuple has 12 components, whereas compiled artifacts have 15, adding uint16 panelSize, quorum and agreed before issuedAt.

      The documented signature selects 0xcb2c90fe; compiled methodIdentifiers contains only v2 selector 0x383f5938.

      A call encoded from the documented ABI dispatches to no function and reverts before validation regardless of its signed values.

      Expected: constructor arity and runtime selector match the compiled contracts; actual: both differ.

      Executed forge test --offline --out test/scratch/out --cache-path test/scratch/cache --match-path test/scratch/JudgeEvidence.t.sol -vv: test_documentedSelectorMissesBothFeedDispatchers confirms 0xcb2c90fe and empty-data dispatch reverts on both concrete feeds from the authorized relayer, while a v2-shaped call reaches InvalidSignature. test_documentedConstructorEncodingReverts appends the documented ten words (pinned attester, pinned relayer,1,3,pinned reporter,0,0,1,86400,2000) to the actual creation code; CREATE fails for both feeds because word two is interpreted as maxDeviationBps greater than 10000.

    • mediumManifest omits the approved vault because no distinct production spot-feed artifact existslaunch.json:9

      The executable contracts list deploys only PriceFeed and NhiFeed, omitting CDPVault, its separately addressed spot feed and its constructor-created CompToken/MockWorkOracle. The approved increment therefore has no deployable vault topology. Only two concrete production feed identifiers exist; SwarmFeed is abstract.

      DeployComp creates PriceFeed twice, but the canonical manifest requires unique contract identifiers and has no instance alias field. Notes describing the blocker do not deploy the missing contracts. Merge of audit_economics, audit_permissions and audit_flow.

      Add a distinctly named concrete spot-feed artifact and its ABI, then include it and CDPVault in dependency order with the existing approved collateral and zero COMP/oracle constructor arguments. This is a source/manifest conflict, not a demand for later service attestation or unsupported manifest fields.

      Parse current launch.json: contracts is exactly [PriceFeed(86400,2000), NhiFeed(86400,2000)].

      Trace both constructors in src/PriceFeed.sol and src/NhiFeed.sol through SwarmFeed: neither constructs a vault or another feed.

      Executing this list yields exactly two application feed addresses and no CDPVault.

      Expected: three distinct feed addresses and CDPVault(0xe44ab81ce23d34e29383dd158a1dffeb1c10d439,0,0,primary,nhi,spot).

      Reusing either listed feed as spot causes the CDPVault constructor equality guard at src/CDPVault.sol:131-134 to revert InvalidFeed; listing PriceFeed twice violates the canonical unique-contract-name refinement.

      The only second price-feed instance currently appears in script/DeployComp.s.sol:70, which the manifest execution does not run.

      Local Foundry evidence test test_reusingEitherManifestFeedAsSpotReverts executed successfully and confirms InvalidFeed for both attempted substitutions.

    • mediumManifest still omits the approved vault and its distinct production spot feedlaunch.json:9

      Previous finding 0c7887ba9781551cfd751e7ad6c9488471f044057f1528f91783b9205cc5b9d2 remains unresolved. The executable contracts list deploys only PriceFeed and NhiFeed. Neither constructor creates CDPVault or a separate spot feed, so the approved vault increment and its constructor-created CompToken/MockWorkOracle are absent.

      The author correctly identifies a source/manifest dependency gap outside a manifest-only repair scope. An accepted, distinctly named concrete production spot-feed artifact and its ABI must first be supplied by a source-producing assignment; then a manifest assignment can add that feed and CDPVault in dependency order. Preserve existing collateral, pinned authorities and zero child-contract arguments.

      Notes and later services do not supply the omitted deployment operations. This merges all specialist reports of the same topology defect.

      Parse launch.json: contracts is exactly PriceFeed(["86400","2000"]), NhiFeed(["86400","2000"]).

      Trace src/PriceFeed.sol and src/NhiFeed.sol constructors through SwarmFeed: only the two feeds are created; there is no CDPVault constructor call.

      Expected: three distinct feeds followed by CDPVault(0xe44ab81ce23d34e29383dd158a1dffeb1c10d439,0,0,primary,nhi,spot), which creates and binds CompToken and MockWorkOracle.

      Actual: two feeds and no vault or children.

      CDPVault.sol:131-134 rejects spot equal to primary or NHI with InvalidFeed.

      Listing PriceFeed twice violates the canonical unique-contract-name refinement; accepted src has only PriceFeed and NhiFeed as concrete feed identifiers and SwarmFeed is abstract.

      The deployment script creates PriceFeed twice, but manifest execution does not run that script.

      Executed FOUNDRY_TEST=test/scratch/judge forge test --offline --out test/scratch/judge-out --cache-path test/scratch/judge-cache --match-path test/scratch/judge/JudgeTopology.t.sol -vv: all four topology checks passed.

      The two listed feed constructors each leave creation nonce 1 and no child at nonce 1; the primary-as-spot and NHI-as-spot cases revert InvalidFeed; a separately created third PriceFeed allows construction and both child vault links equal the new CDPVault.

      The positive control uses vm.etch to place a MockIMD fixture at the approved address; it makes no assertion about current Sepolia state.

      Separately parsed the unique-name refinement: appending another PriceFeed produces duplicate identifiers and is invalid.

  13. ManifestAgent #1120no change

    The finding reproduces. Repair requires an accepted, distinctly named production spot-feed contract and ABI, outside this assignment’s scope. launch.json remains unchanged.

    Recorded the evidence and scope dispute in .imd-responses.json.

    forge build passed. forge test: 206 passed, 0 failed, 2 skipped, including all four reproduction checks.

    • mediumManifest still omits the approved vault and its distinct production spot feedlaunch.json:9

      Previous finding 8c223e25991a4d0a8a1472197470433e50586fcbb6e05f7db12d2887ce1fa599 remains unresolved. The author confirms the defect and disputes only repairability within the manifest-only assignment. The executable contracts list still deploys only PriceFeed and NhiFeed.

      Their constructors create no CDPVault or third feed, so the approved vault increment and its constructor-created CompToken and MockWorkOracle are absent. A source-producing assignment must supply an accepted distinctly named concrete production spot feed and its ABI; a subsequent manifest assignment must list it before CDPVault, retaining the approved existing collateral, pinned authorities and zero child-contract arguments.

      Notes and later services do not execute the omitted constructors. Duplicate specialist topology reports are merged here.

      Parse launch.json: contracts is exactly PriceFeed(["86400","2000"]), NhiFeed(["86400","2000"]).

      Trace src/PriceFeed.sol:22-35 and src/NhiFeed.sol:21-34 through src/SwarmFeed.sol:99-137: they only initialize their own feed state and create no child contracts.

      Expected: three distinct feeds followed by CDPVault(0xe44ab81ce23d34e29383dd158a1dffeb1c10d439,0,0,primary,nhi,spot), whose constructor creates and binds CompToken and MockWorkOracle.

      Actual: only two feeds, no vault or children.

      CDPVault.sol:131-134 rejects primary or NHI reused as spot with InvalidFeed.

      Source declares only PriceFeed and NhiFeed as concrete production feeds; SwarmFeed is abstract.

      Listing PriceFeed twice violates the canonical unique-contract-name refinement, and script/DeployComp.s.sol is not a manifest operation.

      Executed FOUNDRY_TEST=test/scratch/review forge test --offline --out test/scratch/review-out --cache-path test/scratch/review-cache --match-path test/scratch/review/*.t.sol -vv.

      All four JudgeTopologyTest checks passed: both listed feeds have creation nonce 1 and no child at nonce 1; primary-as-spot and NHI-as-spot revert InvalidFeed; a separately deployed third PriceFeed permits construction and both child vault links equal CDPVault.

      The positive control uses vm.etch with a local MockIMD fixture at the approved address, not live Sepolia evidence.

      Separately parsed the manifest and checked that duplicating PriceFeed fails identifier uniqueness.
