The whole request

Deploy this repository to Ethereum mainnet as it is. Do not change contract logic, fee numbers, roles, limits or events; make only changes strictly required for deployment and list every change you make.

Deployment calls nothing but these constructors, in this order:

  1. KeelToken: no arguments (EIP-1167 clone template).
  2. KeelVault: $owner.
  3. KeelFactory: $owner, $contract:KeelVault, $contract:KeelToken, hookSaltStart 0. The constructor searches the CREATE2 salt on chain and deploys KeelHook itself; do not deploy KeelHook separately. Simulate this constructor before sending it; tests measured about 6 million gas.
  4. KeelRouter: $owner, $contract:KeelFactory.

The owner finishes setup afterwards with separate transactions: vault.wire(factory), factory.setSigner, factory.setStartTickBounds, vault.setVerifier, router.setEthPool, then factory.setPaused(false). The factory stays paused after deployment.

Keep forge build, forge test and forge fmt --check passing. Publish the deployed addresses of KeelToken, KeelVault, KeelFactory, KeelHook and KeelRouter.

  2. Audit imported codeAgent #1082found 2 medium, 2 low, 1 info

    Review complete. The findings file is at the repository root and the tree is unchanged apart from it and my scratch tests.

    Outcome. No loss-of-funds, access-control, reentrancy or accounting defect reproduced. The contracts are tightly guarded and the shipped suite is thorough. Five findings are recorded in .imd-findings.json, two medium, two low, one info.

    Findings

    • Medium, close snapshot capture (KeelVault.sol:275). The basket is paid pro rata to balances at block close - 1, and the close is announced seven days ahead and visible in the mempool. A buyer who enters one block before close and exits the block after extracts most of the basket. In the attached proof a 20,000 IMD one-block round trip returns 47,166 IMD, taking 55% of a basket a launch-time holder funded. The proof test fails on the current code. Suggested fix is a snapshot that is not predictable from the close transaction, such as the announce block or a time-weighted balance over the notice window, which needs a scope decision.
    • Medium, launch policy: proxies and initializers (KeelFactory.sol:201). Every launched token is a 45-byte EIP-1167 clone containing DELEGATECALL, configured by initialize after creation. The five deployed runtimes contain no forbidden opcodes, so the protected suite does not catch it. No exploit follows, but the policy forbids the pattern and removing it changes launch logic, which the brief forbids. Flagged for the adapter's decision.
    • Low, post-deployment configuration (KeelVault.sol:107). Six owner transactions are required before anything works, and wire is a one-shot initializer. This matches the brief's schedule and all six are owner-only and validated, so it is recorded as a policy note with the exact reverting state.
    • Low, dead tick range (KeelFactory.sol:120). The bounds setter accepts maxima up to 886,999, but any start tick at or above 349,200 always reverts in launch because the locked liquidity exceeds v4's per-tick cap. Confirmed by launching at 349,000 and 349,200.
    • Info, factory constructor gas (KeelFactory.sol:99). The salt search length is fixed by the final factory address and the pinned start of 0. Tests saw 9,434 and 2,005 attempts; the mainnet number is only known from the deployer's simulation.

    Coverage. I read all ten files under src/ in full, the test helpers, the README, the validation notes and the protected suite, and traced the v4 hook-delta path in the vendored Hooks and PoolManager libraries. I verified by test that all five runtimes pass the protected opcode scan and that no reachable start tick makes the locked position need more than the supply. I did not audit the vendored OpenZeppelin or Uniswap v4 code beyond those paths, and I did not fuzz the metadata JSON parser or compare the quote library against the v4 swap loop line by line.

    Test notes for the adapter. Holders who keep tokens as PoolManager ERC-6909 claims at the snapshot are excluded from claims; this is self-inflicted and not reported. One harness caveat: under via-IR, vm.roll(block.number + 1) evaluated twice in one function reused the cached first value, so new snapshot tests should roll to explicit block numbers.

    • mediumClose snapshot at block.number-1 lets a one-block buyer capture most of the holder basketsrc/KeelVault.sol:275

      KeelVault.close() freezes poolAtClose = basket and pays it pro rata to token balances at block.number - 1 (claimable() at src/KeelVault.sol:293).

      The close is announced publicly at least 7 days ahead (announceClose) and the owner's close transaction is visible in the mempool, so anyone can buy tokens from the permanently locked, deep, one-sided pool in the block before close, hold for exactly one block, claim a basket share proportional to what they bought, and sell back the next block.

      The round trip costs only the two 1% hook fees plus price impact, while the basket (funded by swap fees and third-party deposits over the project's lifetime) is redistributed to the largest last-block balance. The README's protection only covers transfers in the close block itself, not the block before it.

      Victims are the long-term holders whose pro-rata share is diluted; the attacker is unprivileged and needs only ordinary capital for one block (no flash loan is needed, but any capital source works).

      Minimal fix that preserves the holder-claim design: make the snapshot unpredictable or time-weighted, e.g. snapshot at the announceClose block (or a random block inside the notice window committed at announce) instead of close-1, or use time-weighted checkpoints over the notice period. Any of these changes the Project accounting slightly and needs a scope decision.

      State: launched token at startTick -100000, creatorBps 3000; holder buys with 1e22 IMD via router; vault.deposit(token, 5e22); hook.distribute(token); announceClose; +31 days.

      Block 101: raider buys with 2e22 IMD (receives 2.1455e26 tokens).

      Block 102: owner calls close(token) -> snapshot = 101, poolAtClose = 50,180e18.

      Raider: claim(token) = 27,564.5e18 IMD; sell all tokens back = 19,602e18 IMD.

      Raider total out 47,166.5e18 vs 20,000e18 in: net +27,166.5e18 IMD.

      Holder (bought at launch) claims only 22,615.5e18 of the 50,180e18 basket.

      Expected: a one-block round trip should not extract basket IMD; actual: it extracts 55% of it.

    • mediumLaunched tokens are EIP-1167 DELEGATECALL proxies with a post-deployment initializersrc/KeelFactory.sol:201

      Every token the factory launches is an OpenZeppelin Clones minimal proxy (45 bytes of runtime containing DELEGATECALL 0xf4) that forwards to the shared KeelToken implementation deployed as manifest contract 1, and it is configured by KeelToken.initialize(name, symbol, to) (src/KeelToken.sol:26) after creation rather than by a constructor.

      The launch policy forbids proxies, DELEGATECALL and initializers in application contracts; the protected suite only scans the five runtimes deployed at launch (KeelToken, KeelVault, KeelFactory, KeelHook, KeelRouter), which contain no 0xf4/0xf2/0xff opcodes, so this is not caught by it.

      There is no upgrade path (the implementation address is immutable and KeelToken has no delegatecall of its own) and the implementation locks itself in its constructor, so no exploit follows from the pattern: the initializer is guarded by _initialized and the factory initializes each clone in the same transaction it creates it.

      A side effect is that anyone can clone the public implementation and initialize a lookalike token minted to themselves; such a clone is not isLaunched and the router and hook reject it.

      Reported so the adapter can decide: removing it means replacing cloneDeterministic + initialize with new KeelToken{salt: cloneSalt}(name, symbol, address(this)) (constructor-configured, no proxy), which changes the launch gas and the clone address derivation (the IMD-ordering loop must then use the KeelToken creation-code hash). The brief says not to change logic, so this is a scope decision, not a code defect.

      After any launch(): address(token).code.length == 45 and the bytes are 363d3d373d3d3d363d735af43d82803e903d91602b57fd5bf3, byte 0xf4 (DELEGATECALL) present.

      KeelToken(token).initialize("x","y",anyone) reverts AlreadyInitialized, but Clones.clone(implementation) by any EOA followed by initialize("Keel Project","KEEL",attacker) succeeds and mints 1e27 to attacker; factory.isLaunched(rogue) == false.

      Expected by the launch policy: no proxy, no DELEGATECALL, no initializer; actual: all three in every launched token.

    • lowSix owner transactions configure the system after deployment, including a one-shot wire() initializersrc/KeelVault.sol:107

      Nothing works right after the four constructors run: the factory is paused and has no signer or tick bounds, the vault has no factory/hook (wire) and no verifier, and the router has no ETH pool.

      The brief schedules these as separate owner transactions (vault.wire, factory.setSigner, factory.setStartTickBounds, vault.setVerifier, router.setEthPool, factory.setPaused(false)), so this is consistent with the request, but the launch floor forbids post-deployment initialization, and wire() in particular is a one-time initializer: it can only ever be called once (AlreadyWired) and permanently binds the vault to the factory and hook it reads from factory.hook().

      All six are onlyOwner and wire() validates factory.vault() == this and the hook's factory/vault back-references, so there is no access gap; if the owner wires a factory whose vault is this one but whose token implementation or hook is wrong, it cannot be undone and a new vault+factory pair must be deployed.

      The factory and vault could instead take each other's addresses in constructors only with a CREATE2 address precomputation (the vault needs the factory address and the factory needs the vault address), which is a design change beyond the brief; alternatively the signer, tick bounds, verifier and ETH pool parameters could be constructor arguments with the setters retained for rotation.

      Deploy KeelToken(), KeelVault(owner), KeelFactory(owner, vault, token, 0), KeelRouter(owner, factory) and call nothing else. factory.paused() == true, factory.signer() == 0, factory.tickBoundsSet() == false, vault.factory() == 0, vault.verifier() == 0, router.ethPoolConfigured() == false. factory.launch(...) reverts Paused(); after setPaused(false) it reverts NotConfigured(); router.quoteExactInput(address(0), IMD, 1e18) reverts EthPoolNotConfigured(). vault.wire(factory) succeeds once; a second wire() reverts AlreadyWired().

    • lowsetStartTickBounds accepts start ticks at or above 349,200 that launch() can never usesrc/KeelFactory.sol:120

      The bounds check only requires -887200 <= minimum <= maximum <= 886999, but launch() computes the whole-supply liquidity for [lower, 887200] and rejects it when it exceeds Pool.tickSpacingToMaxLiquidityPerTick(200) (src/KeelFactory.sol:215).

      For every start tick whose lower tick is >= 349,400 (start tick >= 349,200) that liquidity is above the per-tick cap, so a permit signed for such a tick is unusable and the creator's launch transaction reverts after paying for signature, UUID, metadata and clone-address work. No funds are at risk and the signer can re-issue a permit; an owner who sets maximum above 349,199 gets a silently dead range.

      Minimal fix: cap maximum at 349,199 in setStartTickBounds (or compute the per-tick-liquidity check there), keeping the launch check as is.

      factory.setStartTickBounds(-887200, 886999) succeeds.

      With a valid permit for startTick 349000, launch() succeeds; with valid permits for startTick 349200, 400000 and 886999, launch() reverts InvalidLiquidity() (selector 0x1fff9681) because lockedLiquidity would exceed tickSpacingToMaxLiquidityPerTick(200).

      Expected: any tick accepted by the bounds can launch; actual: ticks in [349200, 886999] always revert.

    • infoKeelFactory constructor gas is set by its final address and the pinned hookSaltStart of 0src/KeelFactory.sol:99

      The constructor mines a CREATE2 salt until the low 14 bits of the hook address equal 0x28cc. The attempt count is a deterministic function of the factory's own address, the vault address and the compiler output, and the manifest fixes hookSaltStart at 0, so the on-chain count differs from every test measurement and is only known once the deployer simulates the real addresses.

      The expected count is 16,384 at roughly 147 gas per attempt on top of about 1.2M fixed gas; P(attempts > N) = (1 - 2^-14)^N, so about 5% of address pairs need more than 49,000 attempts (about 8.4M gas total) and about 0.2% need more than 100,000 (about 16M gas).

      This is not a defect; it is the number the deployer's gas ceiling must be checked against before the launch is sent, and if the simulation exceeds the ceiling the only lever is a different hookSaltStart in the manifest.

      In the shipped tests the same constructor needs 9,434 attempts and 6,000,580 gas (docs/VALIDATION.md); in a fresh harness deployment it needed 2,005 attempts (factory.hookSaltAttempts()). On mainnet the count is fixed by the CREATE2 address the project factory assigns and cannot be predicted from these numbers.

  5. Audit permissionsAgent #351found 1 medium, 1 low

    The review is complete. The findings file is valid, both snippets match the tree exactly, the scratch directory is removed, and the working tree holds nothing new except .imd-findings.json.

    Outcome

    The permission model across the five contracts holds up well. Every role-restricted entry point has the guard its effect needs, the three callback entry points pin their caller and a transient value set by the originating call, and every change to a fee split (lower share, deactivate creator, close) flushes the hook's pending fees first, so collected fees cannot be re-split after the fact. Unsigned creatorBps, the inactive-creator redirect and the post-close creator payout are all documented in the README as intended, so I recorded them as trust assumptions rather than defects. The full existing suite passes (74 of 74 tests).

    Findings written to .imd-findings.json

    • Medium, pre-announcement basket capture. announceClose fixes the snapshot at the previous block, so an unprivileged buyer who lands one block before the owner's announcement lands, then sells the block after, keeps full claim rights. Measured in the project's own fixture: the raider claims about 27,630 of the ~50,180 IMD basket and nets +27,232 IMD while the legitimate holder drops to 22,669. The owner's transaction is visible in the public mempool, which is the race amplifier. ADAPTATION.md acknowledges this residual, but nothing deployed enforces private submission.
    • Low, one-step renounce locks funds. KeelVault.renounceOwnership is irreversible and leaves every Building basket uncloseable and teamAccrued unclaimable forever, while reimbursements remain the only exit. Reproduced with the former owner reverting on both announceClose and claimTeam.

    Coverage

    All 45 listed entry points have a row (42 hold, 3 reference the two findings), plus two invariant rows. No entry point was left unreached. The static-analysis leads in my area (HookMiner shift order, encodePacked hash, router locking ether, reentrancy) were checked and are false positives; the remaining tool lines concern fee math and timestamps outside my assigned guides.

    • mediumClose snapshot (announce block - 1) is capturable by a buyer who lands one block before the owner's announceClose: unprivileged mempool race diverts the basket from real holderssrc/KeelVault.sol:258

      Trust-gap seam (access x asymmetry, 'race' amplifier). The owner-only announceClose fixes the claim snapshot at the previous completed block, and the README states claim rights do not follow transfers after the snapshot while a buyer 'cannot observe the on-chain notice and acquire a share'. The protection only covers purchases in the announce block itself.

      The owner's announceClose transaction is visible in the public mempool before inclusion; any searcher or block builder who sees it can execute a buy through KeelRouter in the block immediately before it lands (block N-1), let the announcement land at N (snapshotBlock = N-1), sell the whole position at N+1 with no further price exposure, and still claim a pro-rata share of the frozen basket after close.

      The legitimate holders who funded or earned the basket are diluted by exactly that amount. Only two round-trip Keel fees (1% each) and the self-reversed price impact are paid, while the basket share is pure profit; the raid is profitable whenever the basket is a meaningful fraction of the pool's depth, which is the normal state for a Building project with deposits.

      ADAPTATION.md acknowledges the residual, but nothing in the contracts or the brief's setup enforces private submission of announceClose, so the asymmetry is live on mainnet as deployed.

      Preserving the design (historical snapshot, owner-chosen timing), the minimal mitigations are operational (submit announceClose only through a private relay) or a snapshot the owner commits to without revealing (e.g. snapshot = announce block - K with K chosen from a sealed commitment), which is a scope decision for the author.

      Fixture: KeelTestBase setUp (token launched at tick -100000, creatorBps 3000; alice and bob each hold 1e27 IMD approved to the router).

      1. alice buys with 10,000e18 IMD via router.swapExactInput(IMD, token, 10000e18, 1, ts, alice) - legitimate holder.

      2. owner deposits 50,000e18 IMD into the basket via vault.deposit(token, 50000e18).

      3. roll +5 blocks.

      4. block N-1: bob (who saw announceClose pending) buys with 20,000e18 IMD and receives got tokens.

      5. block N: owner calls vault.announceClose(token); snapshotBlock = N-1.

      6. block N+1: bob sells all got tokens back for IMD.

      7. warp +31 days, roll +1, owner calls vault.close(token).

      Expected (README guarantee): bob, who held nothing before the notice and nothing after it, has no basket entitlement; alice's entitlement is the full basket.

      Actual (measured): vault.claimable(token, bob) = 27,629,777,566,886,255,772,183 and vault.claimable(token, alice) = 22,669,022,433,113,744,227,817; after bob calls vault.claim(token) his IMD balance is 27,231,777,566,886,255,772,183 higher than before step 4 while holding zero tokens.

      The basket funded for alice is more than half diverted to the raider.

    • lowOne-step renounceOwnership on KeelVault permanently locks every Building basket and the team balance (no close, no claimTeam, no verifier/creator-status changes)src/KeelVault.sol:13

      Access-control footgun inherited from Ownable2Step: ownership transfer is two-step, but renounceOwnership() is a single irreversible call that sets owner to address(0). On KeelVault every exit path for basket IMD except verifier reimbursements (announceClose, cancelClose, close) and the only exit path for teamAccrued (claimTeam, which also pays owner()) is onlyOwner.

      After a renounce, holders of every Building project can never claim because the project can never reach Closed, teamAccrued keeps growing with 10% of every future fee and can never be paid, and setVerifier/revokeVerifier/setCreatorActive/setRunPrice become unreachable.

      This is an owner-side mistake rather than an attack and is reported as a trust assumption with a concrete locked state; a minimal fix that preserves all requested roles is to override renounceOwnership to revert (as several protocols do when ownerless operation is not a supported state), or to document the lock explicitly in the operator runbook.

      Fixture: KeelTestBase setUp.

      1. alice buys with 10,000e18 IMD (fee pending in hook).

      2. owner deposits 50,000e18 IMD into the basket.

      3. hook.distribute(token) so teamAccrued > 0.

      4. owner calls vault.renounceOwnership(); vault.owner() == address(0).

      5. roll +1 block; vault.announceClose(token) from the former owner reverts OwnableUnauthorizedAccount; vault.claimTeam() reverts OwnableUnauthorizedAccount; no other address can call them either.

      Expected: some path exists to close the project and pay the 50,180e18 IMD basket to holders and the team balance to the team.

      Actual: vault.claimable(token, alice) stays 0 forever, teamAccrued (100e18 after step 3) stays locked, totalOwed can only decrease via verifier reimbursements to the creator.

  6. Audit mathAgent #61found 1 info

    The findings file is in place and excluded from git by the harness as expected. The scratch directory is removed and the tree is otherwise untouched.

    Result: no exploitable arithmetic defect found in the assigned area. The review covered the Math Precision, Boundary and Numerical Gap guides against all five contracts and the two libraries that carry math.

    What I traced and fuzzed

    • Hook fees: all four swap shapes (exact-in and exact-out, buy and sell). Fee equals floor of 1% of gross IMD for exact-input paths and ceilDiv(net, 99) for exact-output paths, and the v4 delta-sign plumbing matches. Fees truncate to zero below 100 wei IMD, which is gas-dominated dust.
    • Vault split: team floor plus creator floor plus exact remainder always sums to the amount, and the 1000 + 8000 bps cap rules out underflow. Claims use mulDiv floor so the sum never exceeds the frozen pool. Fuzz confirmed at most 1 wei of dust.
    • Launch liquidity: floor-to-next-spacing lower tick handles negative remainders, the liquidity formula uses 512-bit intermediates, and the resulting amount0 can never exceed supply. The tick bound at 349,199 matches the per-tick cap.
    • Router quote: V4Quote mirrors Pool.swap including protocol fees, and its int24 tick arithmetic fits for every allowed spacing up to 32,767. Quote equalled actual output across random amounts in both directions.
    • Checkpoints and casts: every narrowing cast is bounded before it runs. Snapshot blocks always precede the close block, so past lookups cannot revert.

    One informational entry: a project closed while every token sits in the pool or dead address has zero circulating supply, so the frozen basket, including third-party deposits, is permanently unclaimable while still counted in totalOwed. I reproduced it with a 1000 IMD deposit and a buy-then-sell-back. The README and an existing test state this is intended, so it is recorded as a documented trust assumption rather than a defect, with the reproduction attached for the judge.

    Coverage: all 45 entry points have rows (42 hold, 3 point to the informational entry), plus three invariant rows. The project suite of 74 tests passes unchanged.

    • infoBasket frozen at close with zero circulating supply is permanently unclaimable (documented behaviour, boundary x invariant seam)src/KeelVault.sol:295

      Seam: boundary (circulating == 0) x invariant (every wei counted in totalOwed has a claimant). close() freezes poolAtClose = basket and computes circulating = totalSupply - balanceAt(POOL_MANAGER, snapshot) - balanceAt(DEAD, snapshot).

      When every token sits in the pool or the dead address at the snapshot block, circulating is 0, claimable() returns 0 for every address, claim() always reverts NothingToClaim, and no other function (accrue in Closed phase credits the creator only, deposit requires Building, there is no sweep) can ever move the frozen basket.

      Deposits made via deposit() by the creator or third parties, plus the basket share of all swap fees accrued during Building, are lost while still counted in totalOwed forever.

      README section on closing states this outcome explicitly ('If circulating supply is zero, no claims are available and the pool remains locked'), and test/KeelVault.t.sol testZeroCirculatingAndExcludedAddressesCannotClaim asserts it, so this is reported as a documented trust assumption and not as a defect: the author may still prefer to route a zero-circulating basket to the creator or back to depositors rather than strand it.

      All other arithmetic in the assigned area (hook fee grossing, vault split, launch liquidity, quote mirror, checkpoints, claim rounding) was traced and fuzzed and holds.

      Setup as test/helpers/KeelTestBase.sol.

      1. Anyone calls vault.deposit(token, 1000e18) (Building phase).

      2. alice buys 100e18 IMD worth of token via router and sells the entire balance back in a later block, so the pool again holds every token outside DEAD.

      3. hook.distribute(token); basket is now 1000e18 + fee share (observed 1001194000000000000001 wei).

      4. Owner: roll one block, announceClose(token); warp 31 days, roll, close(token).

      Expected: the 1001.19 IMD basket is claimable by someone or returned to the depositor.

      Actual: project.circulating == 0, poolAtClose == 1001194000000000000001, claimable(token, X) == 0 for alice, creator and the depositor, claim(token) reverts NothingToClaim, totalOwed still includes the amount and no entry point can release it.

      Probe test (scratch, not kept) testZeroCirculatingLocksDeposit passed asserting exactly this state.

  7. Audit economicsAgent #3found 1 medium, 3 low

    The review is complete. The only file written is .imd-findings.json at the repository root. The scratch tests live under test/scratch/, which is git-ignored, and git status shows no other changes.

    What I audited. The Economic Security, Invariant and Flow Gap guides against all five contracts, with the vendored Uniswap v4 PoolManager executing for real in Foundry. I also pulled the live IMD token from mainnet: it is a LayerZero OFT-style ERC-20 with no pause, tax or blacklist, so the vault's exact-balance and solvency checks hold against the real dependency.

    Findings, ranked:

    1. Medium, with a proof test. Claim rights vest after one completed block and survive an immediate sale. A buy landing in the block before the owner's announceClose transaction, followed by a sale in the announcement block, keeps a full pro-rata basket claim. In the reproduction the attacker spends 398 IMD in round-trip fees and claims 27,630 IMD, cutting the honest holder's claim from 50,299 to 22,669 IMD. The proof at test/scratch/SnapshotRoundTripProof.t.sol fails on the current code.
    2. Low. A close with zero circulating supply at the snapshot freezes the basket forever with no recovery path. The reproduction strands 119.4 IMD of fees.
    3. Low. The 1% fee is enforced only in the hooked pool. A hookless parallel TOKEN/IMD pool was initialized and traded in a test with no fee reaching the hook or vault.
    4. Low. A single renounceOwnership call on the vault permanently disables close, announce and team withdrawal, stranding every basket.

    What held. All four swap modes net to exactly the documented fee with the hook's 6909 claims fully backed. The liability sum always equals totalOwed. Launch liquidity was swept across every aligned lower tick and never exceeds supply or the per-tick cap. The router escrows and settles exactly, and the existing 72-test suite passes.

    Coverage. All 44 entry points have a row, plus four invariant rows. Six rows reference a finding and the rest are holds. Nothing was left unreached.

    Not done. I did not run the invariant fuzz suite to completion in this session, and the parallel-pool and renounce findings carry reproductions but no proof file, since proofs are reserved for the most severe.

    • mediumBasket claim rights vest after one completed block and survive an immediate sale, so a one-block buyer ahead of announceClose captures most of the basketsrc/KeelVault.sol:258

      close() pays the frozen basket pro rata to balanceAt(holder, snapshotBlock) (src/KeelVault.sol:298) and snapshotBlock is the block before announceClose lands (line 258). Nothing requires the holder to still own the tokens at close, and the Keel pool has no LP fee, so a round trip through the locked position costs only the two 1% hook fees.

      Anyone whose buy lands in the block immediately before the owner's announceClose transaction (a searcher who sees the pending transaction in the public mempool while that block is still being built, or a builder who includes its own buy and leaves the owner's transaction for the next block) sells everything in the announcement block, retains a full claim, and is paid from the basket after close. The loss falls on the depositors and genuine holders whose share is diluted.

      Concrete economics from the test: alice holds tokens bought with 10,000 IMD, the basket holds 50,298.8 IMD; bob buys with 20,000 IMD in block 101, the announcement lands in 102, bob sells in 102 for 19,602 IMD (round-trip cost 398 IMD), and after close bob claims 27,629.78 IMD (net profit 27,231 IMD, 55% of the basket) while alice's claim falls from 50,298.8 to 22,669 IMD.

      README documents that a snapshot holder may sell and keep its rights, but it also says a buyer cannot acquire a share of the existing basket by observing the notice; a mempool-visible announcement defeats that with no capital at risk for longer than one block.

      Minimal fix that preserves the historical snapshot: pay min(balanceAt(snapshotBlock), balanceAt(closeBlock-1)) so a claim requires the tokens to be held through close (and recompute circulating the same way), or require announceClose to be sent through a private relay and state that operational requirement in the runbook.

      Fixture as test/helpers/KeelTestBase (launch at tick -100000, 30% creator share, block 100).

      1. alice: router.swapExactInput(IMD, token, 1e22, 1, now, alice).

      2. owner: vault.deposit(token, 5e22).

    • lowclose() with zero circulating supply at the snapshot freezes the basket in the vault foreversrc/KeelVault.sol:283

      circulating is total supply minus the PoolManager's and dead address's snapshot balances. If every holder sold back into the locked pool before the snapshot, circulating is 0, close() still succeeds, poolAtClose is set to the basket, claimable() returns 0 for everyone (line 295), accrue() in the Closed phase never credits the basket again and there is no sweep, redistribution or re-open path.

      The fees and deposits in the basket are then permanently stuck while still counted in totalOwed. README states this outcome, but the contract gives the owner no signal before close and no recovery after it. A cheap guard is to revert close() when circulating == 0 (the owner can cancelClose and re-announce once there are holders), or to fold a zero-circulating basket into teamAccrued/creatorAccrued.

      Fixture as test/helpers/KeelTestBase.

      1. alice buys with 1e22 IMD then sells the whole position back; hook.distribute(token) -> basket = 119,400,000,000,000,000,001 wei (119.4 IMD of hook fees).

      2. vm.roll(101); owner: vault.announceClose(token).

      3. warp 31 days, roll 102; owner: vault.close(token).

      Expected: either close reverts so the owner can re-announce later, or the basket is reassigned.

      Actual: project.circulating == 0, poolAtClose == 119.4 IMD, claimable(token, anyone) == 0, totalOwed still includes the 119.4 IMD; no function in KeelVault can ever move it.

    • lowThe 1% Keel fee is enforced only in the factory's hooked pool; anyone can open a hookless TOKEN/IMD pool and trade fee-freesrc/KeelHook.sol:84

      beforeInitialize only validates pools that name this hook. The launched token is a plain ERC-20, so any address can initialize a second Uniswap v4 pool for the same TOKEN/IMD pair with hooks = address(0) (or any other venue), seed it with tokens bought from the Keel pool, and trade there with no Keel fee.

      Once such a pool exists, routers and aggregators prefer it (0.3% LP fee versus 1% hook fee plus 0% LP fee), so the basket, creator and team stop earning on most volume; the Keel pool only sees arbitrage flow. This undermines the stated purpose that the 1% swap fee funds the team, creator and basket. The README notes other addresses cannot add liquidity to these pools but does not mention that parallel pools bypass the fee entirely.

      There is no contract-level fix without transfer-level fees (which would change the token); report it as an economic trust assumption and set expectations in the documentation.

      Fixture as test/helpers/KeelTestBase.

      1. alice buys tokens with 1e22 IMD via the router; hook.distribute(token); record hook.totalPending() and vault.totalOwed().

      2. alice transfers her tokens to an LP contract, mint it 1e24 IMD.

      4. trader: poolManager.swap on that key, zeroForOne=false, amountSpecified=-1e21 -> receives 12,094,451,810,550,954,080,531 tokens.

      Expected per the protocol's purpose: 10 IMD (1%) reaches the Keel fee accounting.

      Actual: hook.totalPending() and vault.totalOwed() are unchanged; no FeePending event; the Keel pool, basket, creator and team receive nothing.

    • lowrenounceOwnership() on KeelVault permanently disables close, announceClose and claimTeam, freezing every basket and the team balancesrc/KeelVault.sol:13

      KeelVault inherits Ownable2Step, which keeps OpenZeppelin's single-step renounceOwnership(). One owner call sets owner to address(0). After that announceClose, cancelClose, close, setCreatorActive, setVerifier, setRunPrice and claimTeam all revert OwnableUnauthorizedAccount, so no Building project can ever close, holders can never claim, and teamAccrued can never be withdrawn; totalOwed is stuck.

      The same single call on KeelFactory leaves launches paused forever if paused was true, and on KeelRouter leaves the ETH route unconfigurable. The two-step transfer protects against a wrong address but not against this one irreversible call.

      Minimal fix: override renounceOwnership() to revert in all three contracts (ownership can still move via transferOwnership/acceptOwnership).

      Fixture as test/helpers/KeelTestBase (basket funded with vault.deposit(token, 1e21), hook fees distributed so teamAccrued > 0).

      1. owner: vault.renounceOwnership().

      2. vault.owner() == address(0).

      3. owner (or anyone): vault.claimTeam() -> reverts OwnableUnauthorizedAccount; vault.announceClose(token) -> reverts OwnableUnauthorizedAccount; vault.transferOwnership(x) -> reverts.

      Expected: ownership can only move, never vanish, while liabilities exist.

      Actual: the basket (1e21 wei) and teamAccrued are unreachable forever; no claim path exists for holders.

  8. Audit flowAgent #1694found 2 low, 1 info

    The review is complete. The findings file is in place at the repository root (the harness's own exclude rule hides it from git status, which is expected), the scratch probe is under the ignored test/scratch directory, and no tracked file was changed.

    Outcome. I found no critical, high or medium defects in the control flow. The fee take, settlement, callback authorization, snapshot and close paths all behave as the README describes, and I verified the hook's delta signs against the vendored Uniswap v4 Hooks library rather than from memory. All 74 existing tests pass, forge build and forge fmt --check pass, and a live read confirmed the mainnet IMD token reports symbol IMD with 18 decimals and that the PoolManager has code.

    Findings written to .imd-findings.json (three, none needing a proof file):

    • Low, fee avoidance via side pools. The 1% Keel fee is only charged on the hooked pool. Anyone can initialize a hookless TOKEN/IMD pool for a launched token, seed it with bought tokens, and trade there. The scratch test shows a 1,000 IMD buy on such a pool leaves the hook's pending balance and the vault's liabilities unchanged. This is inherent to hook-based fees, so I framed it as a documentation gap rather than a code change.
    • Low, PoolManager-held tokens forfeit the close payout. The close computation treats the entire PoolManager balance as the locked launch position. A holder who LPs in a third-party v4 pool, or keeps ERC-6909 claims, holds no ERC-20 balance at the snapshot, gets zero, and their share is silently redistributed to other holders. The scratch test quantifies the transfer between two holders.
    • Info, constructor gas tail. The hook salt search is geometric with mean 16,384 attempts. From the repository's own measurements, the expected mainnet cost is about 7M gas, not 6M, and roughly one in ten factory addresses needs more than 10M. The count is a pure function of the final factory address, so it can be computed off-chain before broadcast.

    Coverage. All 44 listed entry points have a row, plus six invariant and periphery rows. Four rows carry finding verdicts (hook beforeInitialize, vault claim and close, and the HookMiner loop); the rest are holds, each with a one-line reason. Nothing was left unreached. Static-analysis leads I examined and did not promote: the aderyn "incorrect shift order" and "hash collision" lines are false positives (Yul shl argument order is correct; the packed second argument is fixed-width), the "locks Ether" line is wrong because the only payable function requires exact msg.value, and the slither strict-equality lines are tautological assertions.

    Areas not fully covered within budget. I did not test the behavior of the real IMD token under transfer (fee-on-transfer or callbacks) beyond the read-only symbol and decimals check, and I did not independently re-derive every V4Quote step against the pool math beyond confirming the loop mirrors the vendored swap code and the suite's quote-equals-execution tests.

    • lowKeel 1% fee applies only to the hooked pool; anyone can open a hookless TOKEN/IMD pool for the same launched token and trade it fee-freesrc/KeelHook.sol:82

      KeelHook.beforeInitialize only gates pools whose PoolKey.hooks is this hook. The PoolManager lets any account initialize PoolKey(TOKEN, IMD, fee, spacing, hooks=address(0)) for a launched KeelToken, and KeelToken has no transfer restriction, so liquidity bought on the Keel pool can be re-deposited into a side pool.

      Swaps on that side pool call no Keel hook: hook.pending(token), totalPending and vault.totalOwed stay unchanged, so no team/creator/basket revenue is produced for that volume. The README's 'Other addresses cannot add liquidity to these pools' holds for the hooked pool only; the fee is routable-around once a secondary pool has liquidity.

      This is a design property of hook-based fees rather than an access-control bypass, so it is reported as low: the brief fixes the design, and the operator should understand that fee capture is not guaranteed for all on-chain volume. No code change is proposed; document it in the README's Fees section.

      State: fixture from test/helpers/KeelTestBase.sol (token launched at startTick -100000).

      1. alice: router.swapExactInput(IMD, token, 10000e18, 1, now, alice) and transfer the TOKEN to a V4Actor.

      2. Anyone: poolManager.initialize(PoolKey(token, IMD, 3000, 60, IHooks(0)), currentKeelPrice) succeeds (no hook consulted).

      3. actor.modify(sideKey, ModifyLiquidityParams(tick-6000, tick+6000, 1e21, 0)).

      4. hook.distribute(token); record hook.pending(token) and vault.totalOwed().

      5. bob funds actor with 1000e18 IMD; actor.swap(sideKey, SwapParams(false, -1000e18, MAX_SQRT_PRICE-1)) returns amount0 = 38674335312443901156713 TOKEN.

      Expected under the README's fee model: 1% of the 1000 IMD (10e18) reaches the hook.

      Actual: hook.pending(token) unchanged, hook.distribute(token) is a no-op, vault.totalOwed() unchanged.

      Scratch test: test/scratch/Probe.t.sol::testSidePoolSwapPaysNoKeelFee (passes = bypass confirmed).

    • lowHolders whose TOKEN sits inside the PoolManager at the snapshot (side-pool LPs, ERC-6909 claim holders) are silently excluded from the close payout and their share flows to other holderssrc/KeelVault.sol:283

      close() treats the entire PoolManager ERC-20 balance of TOKEN as the locked launch position. But the PoolManager also holds TOKEN for (a) liquidity positions in any third-party pool that uses the token (see finding 1: such pools are permissionless) and (b) users who kept TOKEN as ERC-6909 claims instead of taking them. Those users hold no ERC-20 balance at snapshotBlock, so claimable() returns 0 for them, while their tokens are also subtracted from circulating.

      The basket is therefore split only among ERC-20 holders, who collectively receive the excluded holders' share. The README documents only that PoolManager and dead are excluded; it does not say that a normal LP in another v4 pool forfeits the holder payout.

      Severity low: the loss per victim is bounded by their share of poolAtClose and requires the holder to have parked tokens in the PoolManager at the snapshot, but it is a loss to an identifiable party under ordinary v4 usage, and nothing warns them.

      Mitigation without changing the accounting rules: document explicitly in README 'Closing and holder claims' that TOKEN held inside the PoolManager (any pool position or ERC-6909 claim) at the snapshot carries no claim, so holders must hold ERC-20 balances in their own address before an announcement.

      State: fixture as above plus a hookless side pool PoolKey(token, IMD, 3000, 60, 0) seeded with liquidity.

      1. bob: router.swapExactInput(IMD, token, 5000e18, ...) -> bobTokens = 66655263859868990583995104.

      2. carol: same buy, transfers her TOKEN to her own V4Actor contract and calls actor.modify(sideKey, ModifyLiquidityParams(tick+120, tick+6120, 1e20, 0)), depositing 3814832804697567477101 TOKEN into the PoolManager (single-sided TOKEN range).

      3. owner: vault.deposit(token, 50000e18); roll 1 block; vault.announceClose(token); warp 31 days; roll; vault.close(token) -> poolAtClose = 50120e18, circulating = 299321654024125672005047141 (excludes carol's pooled 3.81e21).

      4. vault.claimable(token, carol) == 0 and claimable(token, carolActor) == poolAtClose * leftoverERC20 / circulating: the pooled TOKEN earns nothing.

      Expected if pooled tokens counted: carol's actor would get an extra 638767629435603859 wei IMD and bob 142245722328333185 wei less.

      Actual: that amount is redistributed to the remaining ERC-20 holders.

      Scratch test: test/scratch/Probe.t.sol::testHolderWhoLPsInSidePoolAtSnapshotGetsNothingAndOthersAbsorbShare.

    • infoKeelFactory constructor gas is geometric in the CREATE2 salt search; roughly one deployment in ten needs more than 10M gas and the brief's 6M figure is a single samplesrc/libraries/HookMiner.sol:21

      HookMiner.find loops until 14 address bits match, so attempts follow a geometric distribution with mean 16,384 and no upper bound. docs/VALIDATION.md measures about 147 gas per candidate plus about 4.6M fixed gas (6,000,352 gas at 9,434 attempts; 4,676,259 at 471). Expected mainnet constructor cost is therefore about 7.0M gas, not 6M, and the tail is fat: P(attempts > 36,700, i.e. > 10M gas) = exp(-36700/16384) = 10.6%; P(> 15M gas) = 1.3%; P(> 25M gas) = 0.03%.

      The attempt count depends on the final factory address (deployer and nonce/salt) and the exact compiled hook init code, so the test figure does not transfer.

      This is not a code defect (the brief pins hookSaltStart = 0 and asks for the search on chain) but it is a concrete deployment-failure state: a deployment whose simulated cost exceeds the service's gas ceiling cannot be fixed by retrying with the same inputs, only by changing the factory's deployment address (different CREATE2 salt for the factory) or the pinned offset, both of which require a revised launch decision.

      Deployment should simulate with the final address before broadcast, as the README already requires, and the gas ceiling should be set with this distribution in mind.

      Deploy KeelFactory(owner, vault, template, 0) from a deployer address D.

      Expected per the brief: about 6M gas.

      Actual: gas = ~4.6M + 147 * attempts where attempts is the first salt whose keccak256(0xff ++ D ++ salt ++ initCodeHash) low 14 bits equal 0x28cc.

      In test/KeelDeployment.t.sol the CREATE2 rehearsal found 471 attempts (4.68M gas) and the CREATE fixture found 9,434 (6.0M gas); test/KeelFactory.t.sol logs other counts for other addresses.

      For any D with attempts >= 36,700 (10.6% of addresses) the constructor costs more than 10M gas.

      The number is a property of the address, so it can be computed off-chain for the intended factory address before sending the transaction.

  10. Audit judgeAgent #724found 1 medium, 3 low, 2 info

    Review complete. .imd-findings.json is written at the repository root with 6 findings and a 47-row coverage record (all 44 entry points answered, plus 3 invariant rows). No repository file was changed; only the findings file and my scratch tests under test/scratch/ (gitignored) were created.

    What I verified first

    • forge build, forge test (89 of 89 pass) and forge fmt --check all pass on the tree as given.
    • The manifest in launch.json matches the four constructors, the brief's order, $owner arguments and hookSaltStart 0, and uses only the schema's keys.
    • The specialists' attached proof fails on this code for exactly the stated reason.

    Findings kept, after reproduction and merging

    #SeverityFinding
    1mediumA buyer who lands one block before a mempool-visible announceClose and sells in the announcement block keeps a full basket claim. Merged from permissions and economics. Bob nets about 27,230 IMD profit and takes 55% of a basket funded for alice. My own proof under test/scratch/KeelSnapshotRaceProof.t.sol fails on this code and is embedded in the finding.
    2lowTOKEN held inside the PoolManager at the snapshot, such as a third-party pool position or ERC-6909 claim, gets no payout and its share flows to other holders. Reproduced with exact numbers.
    3lowclose() with zero circulating supply strands the basket forever while it stays in totalOwed. Merged from math and economics. Documented behaviour, kept as low.
    4lowInherited one-step renounceOwnership() freezes every Building basket and the team balance on the vault. Merged from permissions and economics.
    5infoThe 1% fee only applies to the hooked pool. Anyone can open a hookless TOKEN/IMD pool and trade fee-free. Design property of hook-based fees, downgraded from low.
    6infoFactory constructor gas is geometric in the salt search. The repository's own runs show 471, 5,322 and 9,434 attempts, so the 6M figure is one sample. Deployment concern, not a code defect.

    Specialist claims I corrected

    • The side-pool bypass was recalibrated from low to info because no code change is possible without changing the token, which the brief forbids.
    • The zero-circulating basket is reported once instead of twice, and the one-block snapshot race once instead of twice, each at the higher severity given.

    My own pass found nothing additional. I traced the hook delta accounting against the vendored v4 Hooks.afterSwap, the router's settlement and callback guards, the launch liquidity formula, the checkpoint lookups and all owner, verifier and factory-only paths. The static-analysis leads (hash collision, shift order, locked Ether, strict equality) are all false positives on this code and were left out.

    • mediumClose snapshot (announce block - 1) is capturable by a buyer who lands one block before a mempool-visible announceClose and sells in the announcement block; the basket is diverted from real holderssrc/KeelVault.sol:258

      Merged from audit_permissions and audit_economics (same root cause). announceClose (owner-only) records snapshotBlock = block.number - 1 and close() pays poolAtClose pro rata to balanceAt(holder, snapshotBlock) (src/KeelVault.sol:298) with no requirement that the holder still owns tokens at close.

      The protection the README claims ('a buyer cannot observe the on-chain notice and acquire a share ... including by front-running that announcement in the same block') only covers a purchase in the announcement block itself.

      The owner's announceClose transaction is visible in the public mempool before it is included; any searcher or builder who sees it buys through KeelRouter in the block before it lands (that block becomes the snapshot), then sells the whole position in the announcement block or later, and still claims a full pro-rata share of the frozen basket after close.

      The Keel pool has no LP fee, so the round trip costs only two 1% hook fees plus self-reversed price impact, while the basket share is pure profit paid out of deposits and fees that belonged to the genuine holders. ADAPTATION.md acknowledges this residual but nothing in the contracts or the brief's setup enforces private submission. Nothing in the specialists' claims needed correction except framing: the on-chain same-block guard works; the pre-chain (mempool) version does not.

      Mitigations that preserve the design: pay min(balanceAt(snapshotBlock), balanceAt(closeBlock-1)) and compute circulating the same way, or document that announceClose must be sent only through a private relay.

      Severity medium: funds paid to the wrong party under a specific but default condition (public mempool submission).

      Fixture as test/helpers/KeelTestBase.sol (PoolManager and IMD code at the fixed mainnet addresses, token launched at startTick -100000 with creatorBps 3000 in block 100).

      Expected (README guarantee): bob holds nothing at close and held for one block that was only chosen because the announcement was visible, so claimable(token, bob) == 0 and claim reverts NothingToClaim.

      Actual: vault.claimable(token, bob) == 27,629,777,566,886,255,772,183 wei (27,629.78 IMD, 55% of the basket), claim pays it; alice's claim falls from the whole basket to 22,669,022,433,113,744,227,817 wei.

      Proof test test/scratch/KeelSnapshotRaceProof.t.sol fails on this code with 'one-block holder captures basket: 27629777566886255772183 != 0'.

      The specialists' attached proof (.imd/reads/proofs/Proof_dffafc3b0069.t.sol) was also run and fails for the same reason.

    • lowTOKEN held inside the PoolManager at the snapshot (third-party pool positions, ERC-6909 claims) is excluded from the close payout and its share flows silently to other holderssrc/KeelVault.sol:284

      From audit_flow. close() treats the PoolManager's whole ERC-20 TOKEN balance at the snapshot as the locked launch position. The PoolManager also holds TOKEN for (a) liquidity positions in any permissionless third-party pool for the token (hookless TOKEN/IMD pools can be initialized by anyone, see finding 5) and (b) users who kept TOKEN as ERC-6909 claims instead of taking it.

      Those users have no ERC-20 balance at the snapshot, so claimable() returns 0 for them (line 298), while their tokens are also subtracted from circulating; the basket is split only among ERC-20 holders, who collectively absorb the excluded share. The README documents only the PoolManager and dead exclusions and does not warn that an ordinary v4 LP position or claim balance forfeits the holder payout.

      Loss per victim is bounded by their share of poolAtClose and requires parking tokens in the PoolManager at the snapshot, so low. Minimal mitigation without changing the accounting: document in 'Closing and holder claims' that TOKEN inside the PoolManager (any position or ERC-6909 claim) at the snapshot carries no claim.

      Fixture as test/helpers/KeelTestBase.sol.

      1. bob: router.swapExactInput(IMD, token, 5000e18, ...) -> bobTokens; carol (alice in the probe): same buy -> carolTokens, transferred to her own V4Actor contract.

      2. anyone: poolManager.initialize(PoolKey(token, IMD, 3000, 60, IHooks(0)), currentKeelSqrtPrice) succeeds; carol's actor adds a single-sided TOKEN range [tick+120, tick+6120] with liquidity 1e20, depositing 3,110,884,333,344,899,864,022 TOKEN into the PoolManager.

      3. owner: vault.deposit(token, 50000e18); vm.roll(101); announceClose(token); warp 31 days; vm.roll(102); close(token).

      Measured: poolAtClose = 50,060e18; circulating = bobTokens + carolTokens - 3.11e21 (the pooled TOKEN is excluded).

      1. vault.claimable(token, carolActor) = 22,613,877,378,920,980,413,069 (only its leftover ERC-20 balance), claimable(token, bob) = 27,446,122,621,079,019,586,930.

      Expected if pooled tokens counted: bob's share would be poolAtClose*bobTokens/(bobTokens+carolTokens) = 27,445,637,582,353,676,300,671; actual is larger by 485,038,725,343,286,259 wei, which is carol's pooled share redistributed to bob (and the rest to carol's own leftover balance).

      Scratch test test/scratch/Probe.t.sol::testPooledTokensExcludedFromClaims passes asserting this state.

    • lowclose() with zero circulating supply at the snapshot freezes the basket (deposits and fees) in the vault forever while it stays counted in totalOwedsrc/KeelVault.sol:295

      Merged from audit_math and audit_economics. circulating = totalSupply - PoolManager - dead balances at the snapshot. If every token sits in the pool or at dead at that block, close() still succeeds, poolAtClose is set to the basket, claimable() returns 0 for every address (p.circulating == 0), claim() always reverts NothingToClaim, deposit() requires Building, accrue() in the Closed phase credits only team and creator, and there is no sweep or re-open.

      Third-party deposits and the basket share of all Building-phase fees are stranded permanently while still counted in totalOwed. README states the outcome and test/KeelVault.t.sol::testZeroCirculatingAndExcludedAddressesCannotClaim asserts it, so this is a documented trust assumption rather than an access defect; but the owner gets no on-chain signal before close and no recovery after.

      Cheap guard preserving roles: revert close() when circulating == 0 so the owner can cancelClose and re-announce once holders exist, or route a zero-circulating basket to creatorAccrued/teamAccrued.

      Severity low: owner-controlled condition, documented.

      Fixture as test/helpers/KeelTestBase.sol.

      1. alice: router.swapExactInput(IMD, token, 1e22, ...), then sells the whole position back (pool again holds every token outside dead).

      2. anyone: vault.deposit(token, 1000e18); hook.distribute(token) -> basket = 1,119,400,000,000,000,000,001 wei.

      3. vm.roll(101); owner: announceClose(token); warp 31 days; vm.roll(102); close(token).

      Expected: either close reverts so the owner can re-announce later, or the basket is reassigned to someone.

      Actual: project.circulating == 0, poolAtClose == 1,119.4 IMD, claimable(token, alice|creator|depositor) == 0, claim reverts NothingToClaim, deposit reverts NotBuilding, totalOwed == 1,198,999,999,999,999,999,999 still includes the basket and no entry point can move it.

      Scratch test test/scratch/Probe.t.sol::testZeroCirculatingStrandsBasket passes asserting this state.

    • lowOne-step renounceOwnership() inherited from Ownable2Step permanently locks every Building basket and the team balance on KeelVault (and freezes configuration on KeelFactory/KeelRouter)src/KeelVault.sol:13

      Merged from audit_permissions and audit_economics. Ownable2Step makes transfers two-step but keeps Ownable.renounceOwnership() (lib/openzeppelin-contracts/contracts/access/Ownable.sol:76), a single irreversible owner call setting owner to address(0).

      On KeelVault every exit path for basket IMD except verifier reimbursements (announceClose, cancelClose, close) and the only exit for teamAccrued (claimTeam) are onlyOwner, as are setVerifier/revokeVerifier/setCreatorActive/setRunPrice. After a renounce no Building project can ever close, holders can never claim, teamAccrued keeps growing with 10% of every fee and is never payable.

      The same call on KeelFactory leaves launches paused forever if paused is true (setPaused is onlyOwner) and on KeelRouter leaves the ETH route unconfigurable. README says renouncing 'permanently gives up that contract's administrative powers' and that team withdrawals become unavailable, but not that all holder baskets are frozen.

      Owner-side mistake, so a trust assumption with a concrete locked state; minimal fix preserving the requested roles: override renounceOwnership() to revert (ownership still moves via transferOwnership/acceptOwnership), or document the lock in the operator runbook.

      Fixture as test/helpers/KeelTestBase.sol.

      1. alice buys with 1e22 IMD; owner: vault.deposit(token, 5e22); hook.distribute(token) -> teamAccrued = 10,000,000,000,000,000,000 wei, basket = 50,060e18.

      2. owner: vault.renounceOwnership(); vault.owner() == address(0).

      3. vm.roll(101); vault.announceClose(token) reverts OwnableUnauthorizedAccount for the former owner and everyone else; vault.claimTeam() reverts; vault.transferOwnership(alice) reverts.

      Expected: some path to close the project and pay the basket and team balance.

      Actual: claimable(token, alice) stays 0 forever, 50,060e18 basket and 10e18 teamAccrued are unreachable; totalOwed can only fall via verifier reimbursements to the creator.

      Scratch test test/scratch/Probe.t.sol::testRenounceLocksVault passes asserting this state.

    • infoThe 1% Keel fee is enforced only in the factory's hooked pool; anyone can open a hookless TOKEN/IMD pool for a launched token and trade it fee-freesrc/KeelHook.sol:82

      Merged from audit_flow and audit_economics. beforeInitialize/beforeAddLiquidity only gate pools whose PoolKey.hooks is this hook. The launched KeelToken is a plain ERC-20 with no transfer restriction, so any account can initialize PoolKey(TOKEN, IMD, 3000, 60, hooks=address(0)) in the PoolManager (or list the token anywhere else), seed it with tokens bought on the Keel pool and trade there with no Keel fee: hook.pending, totalPending and vault.totalOwed do not move.

      Once such a pool is liquid, routers and aggregators prefer it (0.3% LP fee vs 1% hook fee), so team, creator and basket stop earning on most volume. This is an inherent property of hook-based fees under the brief's design (the README's 'Other addresses cannot add liquidity to these pools' holds for the hooked pool only); no contract-level fix exists without a transfer-level fee, which would change the token.

      Reported as info so the operator documents that fee capture is not guaranteed for all on-chain volume.

      Fixture as test/helpers/KeelTestBase.sol.

      1. alice: router.swapExactInput(IMD, token, 10000e18, 1, now, alice); hook.distribute(token); record hook.totalPending() and vault.totalOwed().

      2. alice transfers her TOKEN to a V4Actor contract funded with 1e24 IMD.

      3. anyone: poolManager.initialize(PoolKey(token, IMD, 3000, 60, IHooks(0)), currentKeelSqrtPrice) succeeds (no Keel hook consulted); actor.modify(sideKey, ModifyLiquidityParams(tick-6000, tick+6000, 1e21, 0)).

      4. trader funded with 1000e18 IMD: actor.swap(sideKey, SwapParams(false, -1000e18, MAX_SQRT_PRICE-1)) receives 31,582,355,245,354,586,667,018 TOKEN.

      Expected under the README fee model: 10e18 IMD (1%) reaches hook accounting.

      Actual: hook.pending(token) == 0, totalPending and vault.totalOwed unchanged, no FeePending event.

      Scratch test test/scratch/Probe.t.sol::testSidePoolPaysNoKeelFee passes.

    • infoKeelFactory constructor gas is geometric in the on-chain CREATE2 salt search: expected about 7M gas with an unbounded tail, so the brief's 6M figure is one sample and a deployment over the service gassrc/libraries/HookMiner.sol:21

      From audit_flow. HookMiner.find loops until the low 14 address bits equal 0x28cc, so the attempt count is geometric with mean 16,384 and no upper bound; it depends on the final KeelFactory address (the launch factory, launch number and manifest position) and the exact compiled KeelHook init code, so the test figure does not transfer.

      The repository's own measurements show the spread: 471 attempts / 4,676,259 gas (CREATE2 rehearsal), 5,322 attempts, and 9,434 attempts / 6,000,352 gas (CREATE fixture), about 147 gas per candidate over ~4.6M fixed. Expected mainnet constructor cost is therefore about 7.0M gas; P(> 10M) = exp(-36,700/16,384) = 10.6%, P(> 15M) = 1.3%.

      Not a code defect (the brief pins hookSaltStart = 0 and the on-chain search) and far below the block gas limit, but a concrete deployment-failure state: if the deployer's simulated cost exceeds its gas ceiling the launch parks and only a different factory address or a revised offset (a launch decision) changes the outcome. The attempt count is computable off-chain from the intended factory address before anything is sent.

      Deploy KeelFactory(owner, vault, template, 0) from deployer D via CREATE2.

      Expected per the brief: about 6M gas.

      Actual: gas = ~4.6M + 147 * attempts, where attempts is the first salt s such that keccak256(0xff ++ D ++ s ++ keccak256(KeelHook creationCode ++ abi.encode(D, vault))) has low 14 bits 0x28cc. test/KeelDeployment.t.sol found 471 attempts (4.68M gas) for its CREATE2 address, test/KeelFactory.t.sol::testConstructorDeploymentGasAndRuntimeSizes 9,434 attempts (6.0M gas) for its CREATE address and testLogMinerGas 5,322 for another; for any D with attempts >= 36,700 (10.6% of addresses) the constructor costs more than 10M gas.

    Failed on the agent's machine.

    the task produced no changes; the agent's last message was: The accepted launch.json needed no revision. The brief for this round listed no concrete findings, and every check confirms the manifest as it stands.

    What I verified

    • The manifest names exactly the four contracts in dependency order with arguments matching the accepted constructors: KeelToken with none, KeelVault with the owner, KeelFactory with owner, vault, token template and hookSaltStart 0, KeelRouter with owner and factory.
    • It has only the keys kind, contracts and notes. Notes are 1433 characters, well under the limit, and cover the post-deployment owner calls, the paused state, publishing KeelHook from the factory's hook getter, and the change list.
    • No file other than launch.json differs from the accepted tree. The working tree is clean apart from my scratch directory, which is ignored and deleted before submission.

    Checks run

    Protected probe rehearsalpasses

    For the rehearsal I encoded each contract's init code exactly as the manifest describes, with a placeholder owner and factory address, predicted the CREATE2 addresses, and ran the pinned protected test against them. All four runtimes deployed on an empty chain, stayed under the EIP-170 size limit, and contained no forbidden opcodes. KeelFactory's constructor mined the hook salt and deployed KeelHook itself in that run, so the on-chain search works without any pre-existing contract.

    No changes were made this round. The submission is the existing launch.json.
