• 1.lowrecycle() staleness runs from firstCredit, which never refreshes while a balance is outstanding: fresh credits are swept with the stale one, and recycle(creator) chains into recycle(flywheel) in the ssrc/CreatorFeeHook.sol:270

          if (block.timestamp < e.firstCredit + RECYCLE_AFTER) revert NotStale(); // from the first unclaimed credit, so a dust buy cannot reset the clock

  Round 3 moved the recycle clock from Earned.lastCredit to Earned.firstCredit. _creditEarned (line 427) only sets firstCredit when e.amount == 0, so once ANY unclaimed credit on a pool is RECYCLE_AFTER old, recycle() takes e.amount in full (line 271), which includes every credit since, down to one made in the same block.

  Two consequences, both introduced by the round-3 change (merged from two specialists, same root cause, one fix): (1) for an actively traded coin whose flywheel (HolderDrip, SnapshotForwarder, BuybackAndBurn, SweepAndBurn) or creator has not pulled for 7 days, anyone can fold the WHOLE 7 days of earnings through the split, not just the stale part; the README (line 188) says a balance 'untouched for 7 days' is recyclable, which readers take to mean the stale money, not fresh fees.

  (2) recycle(creator) credits the creator's block to the flywheel via _creditEarned (line 283); since the flywheel's e.amount is already > 0 its firstCredit stays old, so recycle(flywheel) succeeds in the same transaction and the block that was meant to 'feed the flywheel' (README line 106) goes to the pot instead, with the platform/pot/deepening cut taken twice. Under the round-2 lastCredit rule the second call reverted NotStale.

  Nobody profits except the platform/pot; the losers are the flywheel's beneficiaries (NFT holders, buyback) and the creator.

  Severity Low: no attacker gain, needs a week of nobody calling the permissionless pull(), but it contradicts the documented recycle semantics and is the only behaviour the round-3 fix set made worse.

  Fix (keeps the design): track two buckets per Earned entry, e.g. {uint128 stale; uint128 recent; uint64 recentSince}: in _creditEarned, if block.timestamp >= recentSince + RECYCLE_AFTER then stale += recent, recent = 0, recentSince = now; then recent += amount. recycle() rolls the same way, requires stale > 0 and recycles only stale.

  And in recycle() credit the flywheel with _credit(fly, rest) instead of _creditEarned so recycled money is never re-recyclable (or set e.firstCredit = block.timestamp on that inflow). Operational mitigation until then: the keeper pulls every module at least weekly.

• 2.lowExact-input buys pay the fee at the marginal post-trade price: 2x nominal at half the pool, 10x at 90%, while exact-output buys of the same coin pay exactly fsrc/CreatorFeeHook.sol:365

          if (feeIsCoin) jigAmount = _sellCoinForJig(key, c, fee);

  For an exact-input buy (JIG in, coin out) afterSwap takes f of the coin output and _sellCoinForJig sells that coin back into the same pool, exact-input with the range edge as the only limit, starting from the price the buyer's own trade just left. The JIG recovered is the cost of the LAST f*G coin the buyer bought (the marginal segment of their own price impact), not f of what they paid.

  On the single-sided launch position every launch-sized buy has real price impact, so the JIG the buyer effectively loses to the fee grows without bound with trade size, while exact-output buys (fee charged on the JIG input, line 351) pay the nominal rate at every size.

  The buyer receives exactly the quoted (1-f)*G coin, so a router quote shows nothing wrong; the loss shows up as the pool keeping far less JIG than the buyer paid, which is all their coin can ever be sold back for, and as the creator (70%) and platform (25%) being credited many multiples of the stated fee.

  Round 3 (#4) recorded the direction ('above nominal, by construction') as Info without the magnitude; measured here it makes the stated 1-10% band untrue for any trade above about 10% of the pool.

  Severity Low: no third party can trigger it, the buyer is not an attacker, and it was accepted as a design property in round 3; reported because the magnitude at realistic launch-sniper sizes (50% of pool -> 2x, 90% -> 10x) was not on the table when it was accepted.

  Fix (keeps the 'fee in the unspecified currency, held as JIG' design): bound the conversion to the nominal JIG value: target = (|specified JIG input| * feePips) / PIPS; run the nested sale as EXACT-OUTPUT for target JIG (amountSpecified = +int256(target), same price limit); read coinUsed from the delta; mint JIG claims for the JIG received; return int128(coinUsed) as the hook delta so the coin not needed stays with the swapper; fall back to pendingCoin only when the price sits at the range edge.

  Alternative: take the buy fee on the JIG input with BEFORE_SWAP + BEFORE_SWAP_RETURNS_DELTA and drop the nested conversion (new hook flags, redeploy).

• 3.lowlaunch() has no caller-stated maximum fee since the round-3 refund change, so a setLaunchFee mined first takes the creator's whole msg.valuesrc/CoinFactory.sol:122

          if (msg.value < launchFeeWei) revert WrongFee(); // a fee update landing before a quoted launch must not revert it; excess is refunded

  Round 3 changed launch() from an exact-fee check to msg.value >= launchFeeWei with the excess refunded. The stated reason is that a creator pads msg.value to survive a fee update; the effect is that the creator no longer bounds what they agree to pay: the fee charged is whatever launchFeeWei is when the transaction executes, up to msg.value.

  The platform (the only caller of setLaunchFee) can raise the fee to msg.value in the same block, or an honest fee update that lands first silently consumes the padding. Before round 3 the same transaction reverted WrongFee.

  The platform is a trusted role, so this is a trust-assumption note under threat-model item (f) rather than a theft, but it is a new privilege the round-3 fix introduced: the platform can now take an arbitrary amount of a creator's ETH, bounded only by what the creator attached.

  Fix: add uint256 maxFeeWei to LaunchParams and revert WrongFee when launchFeeWei > p.maxFeeWei (keep msg.value >= launchFeeWei and the refund). The front end passes the quoted fee plus its tolerance. While there, cache uint256 fee = launchFeeWei; at the top and use it for the check, the payment and the refund (see the Info finding on line 166).

  EXPECTED (the creator's intent and pre-round-3 behaviour): revert WrongFee, or pay 0.01 ETH and refund 0.49 ETH.

• 4.infolaunch() re-reads launchFeeWei from storage after paying the platform, so a fee change inside the platform's receive() strands the creator's refund in the factorysrc/CoinFactory.sol:166

          if (msg.value > launchFeeWei) {

  The refund path compares msg.value with the storage variable launchFeeWei (lines 164, 166, 167) after an external call to the platform. nonReentrant guards launch() but not setLaunchFee().

  If the platform is a contract (a Safe with a module or fallback handler, for example) whose receive() calls setLaunchFee(), the second read differs from the first: with msg.value 0.015 ETH and the fee raised from 0.01 to 0.015 (or anything >= msg.value) during receive, the platform is paid 0.01, msg.value > launchFeeWei is false, and 0.005 ETH stays in CoinFactory forever (no withdraw, no receive, nothing can ever move it).

  Lowering it instead makes the refund larger than the factory holds and the launch reverts. The platform is trusted and gains nothing, so Info (merged from two specialists), but it is the only path by which ETH can be stuck in the factory and the fix is one line: cache uint256 fee = launchFeeWei; at the top of launch() and use fee for the check, the platform payment and the refund.

• 5.info_converting is dead code: v4 never calls afterSwap for the hook's own nested swap, so the fee-skip protection comes from the PoolManager, not the flagsrc/CreatorFeeHook.sol:339

          if (_converting) return (IHooks.afterSwap.selector, 0);

  Hooks.afterSwap in v4-core (lib/v4-periphery/lib/v4-core/src/libraries/Hooks.sol line 293: if (msg.sender == address(self)) return (swapDelta, BalanceDeltaLibrary.ZERO_DELTA);) returns before calling the hook whenever the swap's msg.sender is the hook itself, and the nested conversion in _sellCoinForJig is a poolManager.swap() made by the hook.

  So afterSwap is never re-entered during the conversion, the branch at line 339 is unreachable, and the double-charge / double-credit protection the README ('guarded by _converting so the nested swap is not charged again', line 193) and the threat model attribute to _converting is actually the PoolManager's self-call rule.

  Not a vulnerability (the outcome is correct either way); the two storage writes cost about 5k gas per coin-fee swap and the README's reasoning should cite the v4 rule. The same noSelfCall rule means a seal would not bind a modifyLiquidity call made by the hook itself; the hook has no such code path and must not gain one.

  Fix: delete _converting and its three uses, or keep it as belt-and-braces and correct the comments.

  whole finding

  Static: lib/v4-periphery/lib/v4-core/src/libraries/Hooks.sol line 293 returns before the hook call when msg.sender == address(self); _sellCoinForJig (line 388) calls poolManager.swap from the hook, so msg.sender in Hooks.afterSwap is the hook. Dynamic: any exact-input buy on a creator pool after launch (test/scratch/Judge.fork.t.sol::test_F4, 1,000 JIG in) enters afterSwap exactly once per outer swap; a require(!_converting) placed at line 339 never fires.

• 6.inforegister() checks the flywheel against the deepening address bound at registration time, so a coin launched before setDeepening can name the future LPDeepening as its flywheelsrc/CreatorFeeHook.sol:173

              flywheel == platform || flywheel == pot || flywheel == deepening || flywheel == address(this)

  Until setDeepening() runs, deepening == pot, so the BadFlywheel list excludes only the pot. The deploy order is hook, factory, then LPDeepening (DeployDeepening.s.sol binds it afterwards), and the LPDeepening address is a plain CREATE address predictable from the deployer nonce. A launch in that gap with flywheel == the future LPDeepening passes register(), and setDeepening() to that address later succeeds.

  Consequence: that pool's flywheel slice is credited to LPDeepening and its stale balance is recyclable by anyone to pot/deepening/platform (the flywheel side's remainder goes to the pot), never to the recycler, and LPDeepening.pull() is permissionless, so no value is extractable; it only defeats the stated intent of the exclusion list.

  Fix if wanted: have CoinFactory.launch refuse launches while hook.deepening() == hook.pot() (one line), or have setDeepening refuse an address already registered as a flywheel.

  whole finding

  Sepolia fork (test/scratch/Judge.fork.t.sol::test_F6).

  Deploy hook and factory, do not call setDeepening. launch({... flywheel: X ...}) with X = the address LPDeepening will get.

  EXPECTED: BadFlywheel.

  ACTUAL: PoolRegistered with pools[id].flywheel == X; then vm.prank(owner); hook.setDeepening(X) succeeds and hook.deepening() == X, so every swap on that pool credits X both the 2% deepening slice and the flywheel block.

• 7.inforecycle() re-splits with the platform band of the current feePips, not the band in force when the balance was earnedsrc/CreatorFeeHook.sol:278

          uint256 plat = (amount * platformBps(c.feePips)) / 10_000;

  _split() credits the platform by the band of the fee at swap time; recycle() re-splits the stale creator or flywheel balance by the band of the fee at recycle time. After lowerFee() from the 7-10% band (platform 4000) to the 1% band (platform 2500), a stale balance earned under the old band pays the platform 25% instead of 40% on recycling, with the difference going to the flywheel (creator's stale money) or the pot (flywheel's stale money).

  The recycler never gains and the creator cannot raise the fee, so the only direction is less to the platform. Accept and document, or store the band with the Earned entry.

          accPerToken += (amount * ACC) / live;

  accPerToken grows by floor(amount*1e18/live) but accounted grows by the full amount (line 84). The remainder, less than live wei per pull, is counted as distributed yet is claimable by no token. undistributed() = balance - (accounted - paidOut) excludes it, so it is never re-spread and sits in the contract forever.

  Magnitude is below the live supply in wei per pull (a 10,000-token collection strands at most 1e4 wei per pull), so no fix is required; if wanted, grow accounted by (accDelta * live) / ACC instead of amount so the remainder stays undistributed and is picked up by the next pull.

  Sepolia fork (test/scratch/Judge.fork.t.sol::test_F5).

  ACTUAL: claim returns 9, jig.balanceOf(drip) == 1, undistributed() == 0, so no later pull can ever re-spread the 1 wei.

2. Audit flowAgent #1678found 1 low, 1 info

   Round 4 found nothing above Low. All four round-3 fixes hold. There is one Low, which the round-3 firstCredit change itself introduced, plus one Info. Both are in .imd-findings.json.

   Findings

   1. Low — CreatorFeeHook.recycle (src/CreatorFeeHook.sol:283): one transaction can recycle a stale creator's balance twice, so it lands in the pot instead of the flywheel.

   • recycle(key, creator) moves the creator's block to the flywheel through _creditEarned.
   • _creditEarned (line 427) only restarts firstCredit when the flywheel's balance on that pool is zero. If the flywheel already has an unclaimed credit at least 7 days old, the money just moved to it counts as stale too.
   • So recycle(key, flywheel) succeeds in the same block. The creator's block goes to the pot, the platform/pot/deepening cut is taken twice, and the flywheel's holders get nothing.
   • Under the round-2 lastCredit rule the second call reverted NotStale.
   • I confirmed this with a local harness: real PoolManager, hook at a 0x2844 address, 1% pool, sell, warp 7 days + 1 s, then both recycles. The test expecting NotStale failed with "did not revert". The harness was removed afterwards.
   • Fix: credit the recycled amount with _credit(fly, rest) so it can never be recycled again.

   2. Info — CoinFactory.launch (src/CoinFactory.sol:166): the refund re-reads launchFeeWei after the ETH call to platform.

   • If the platform contract calls setLaunchFee while receiving that ETH, the refund is sized from the new fee.
   • Example: fee 0.01, creator sends 0.012, platform raises the fee to 1 ETH. The 0.002 refund is skipped and stays in the factory, which has no way to withdraw it.
   • The platform is trusted, so this is informational. Fix: read the fee into a local variable once at the top of launch.

   Round-3 fixes

   • seal() order: seal is factory-only, and the factory calls it right after _seed in the same transaction. Between register, initialise, seed and seal, the only outside contact is permit2 moving a plain ERC-20, so nobody gets a turn. If seeding fails the whole launch reverts, so a pool cannot end up registered but unsealed.
   • Factory's own seed: the liquidity lock cannot block it, because seeded is still false when the seed is added. Nobody can front-run it either: only the factory can register, and the pool cannot be initialised until it is registered. Adding zero liquidity (fee collection) goes through the remove path, which the hook doesn't intercept.
   • Launch refund:
     • No reentrancy: launch is nonReentrant and the refund is the last step.
     • A msg.sender whose receive reverts only reverts its own launch.
     • The creator could buy during the refund callback, but would pay the 60% snipe fee; that only hurts them.
   • Constructor checks on the AirdropClaim: both hold.
   • firstCredit across claim epochs: it restarts correctly on a new epoch and after a recycle. The one problem is finding 1.
   • Hook callback order:
     • The nested conversion swap is called by the hook itself, so the PoolManager does not call the hook back. _converting is a backup.
     • No other hook function depends on running in a particular order.

   Scope A (whole repo)

   • (a) Locked LP can't be removed or moved: yes. JIGLaunch, CoinFactory and LPDeepening have no function that transfers the position or removes liquidity. Their only PositionManager calls are mint, increase, and decrease-by-zero to collect fees.
   • (b) Nothing leaves PotVault or AirdropClaim outside merkle distributions: yes. The owner writes each tree, which is a trust assumption.
   • (c) JIG and CreatorCoin supply can't grow: yes. Each is minted once in the constructor.
   • (d) Vesting can't be claimed early or redirected: yes. Whoever funds a schedule picks its start, which is by design.

   • lowRound-3 firstCredit fix lets one transaction chain recycle(creator) into recycle(flywheel), sending a stale creator's block to the pot instead of the flywheelsrc/CreatorFeeHook.sol:283

     recycle() credits the creator's stale creator+flywheel block to the flywheel through _creditEarned. _creditEarned (line 427) only resets firstCredit when e.amount == 0. If the flywheel already holds any unclaimed credit on this pool, its firstCredit stays at that old time, and recycle checks staleness against firstCredit (line 270).

     So the amount just moved to the flywheel can be recycled again in the same block, and the flywheel's whole ledger goes through the split with its block sent to the pot. Under the round-2 lastCredit rule the second call reverted NotStale, because the inflow refreshed lastCredit. The round-3 change introduced this.

     README line 106 says 'a stale creator balance feeds the flywheel'. The chain instead pays the pot, and the platform/pot/deepening cut (30-45%) is taken twice. Any address can run the chain, but it cannot profit from it.

     Who loses: the flywheel's beneficiaries (HolderDrip NFT holders, BuybackAndBurn, SnapshotForwarder coin holders). The same rule also makes a large fresh fee credit recyclable at once whenever an earlier unclaimed credit on the pool is 7 days old. That matches the documented 'untouched for 7 days' only if 'untouched' means 'not claimed'.

     whole finding

     Pool P with creator C and flywheel F = a HolderDrip, default split at a 1% fee (creator 5000 bps, flywheel 2000 bps).

     Day 0: a swap pays a 1,000 JIG fee in JIG, so C gets 500 and F gets 200; both firstCredit = day 0.

     Nobody calls C.claim or F.pull.

     Day 7 + 1 s, one transaction from any EOA: (1) hook.recycle(P, C): 500 is split, 15+10+125 go to pot/deepening/platform and rest = 350 goes to _creditEarned(F, 350).

     F's e.amount was 200 > 0, so firstCredit stays day 0.

     (2) hook.recycle(P, F) succeeds instead of reverting NotStale and splits 550: 16.5 to pot, 11 to deepening, 137.5 to platform, 385 to the pot (line 284).

     Expected (README 'stale creator balance feeds the flywheel', and the pre-round-3 behaviour): step 2 reverts NotStale and F keeps 550 for the holders.

     Actual: F's claimable on P drops to 0 and the holders get nothing from either balance.

     Confirmed locally with a harness.

     It deploys a PoolManager, deploys CreatorFeeHook at a 0x2844-flagged address, uses the test contract as factory, registers a coin0/JIG pool at 1% with ticks -20000..20000, initializes it, adds liquidity, seals, warps past the snipe window, and does an exact-input coin->JIG sell of 1e20.

     After warping 7 days + 1 s, hook.recycle(key, creator) followed by hook.recycle(key, flywheel) in the same block does NOT revert (test asserting vm.expectRevert(NotStale) failed with 'next call did not revert as expected').

     Suggested fix: credit the recycled block to the flywheel with _credit(fly, rest) instead of _creditEarned, so recycled money is never re-recyclable, or set e.firstCredit = block.timestamp for a recycle inflow.

   • infolaunch() reads launchFeeWei from storage after the external call to platform, so the refund can be wrong and the excess stranded in the factorysrc/CoinFactory.sol:166

     launch() pays platform.call{value: launchFeeWei} and then reads launchFeeWei from storage again to size the refund. nonReentrant guards launch() but not setLaunchFee(), and setLaunchFee() is callable by the platform. If the platform contract (for example a Safe with a fallback or module) calls setLaunchFee() inside the ETH receipt, the refund is computed from the new value.

     Raising the fee to >= msg.value skips the refund and the creator's excess stays in CoinFactory, which has no receive or withdraw function, so it is lost. Lowering it makes the refund larger than the ETH the factory still holds, so the launch reverts (or, if the factory holds stray ETH from a forced send, pays that out). The platform is trusted, so this is informational.

     The fix is one line.

     launchFeeWei = 0.01 ether.

     The platform is a contract whose receive() calls factory.setLaunchFee(1 ether).

     A creator calls launch{value: 0.012 ether}(p).

     The platform receives 0.01, sets the fee to 1 ether, and msg.value > launchFeeWei is false.

     Expected: refund 0.002 ether to the creator.

     Actual: no refund, and 0.002 ether stays in CoinFactory for good.

     Fix: cache uint256 fee = launchFeeWei; at the top of launch() and use fee for the check, the platform payment and the refund.

   Review complete. The findings file holds one Low and two Info items; nothing above Low survived a genuine attempt, so on this evidence the swarm phase can close once the Low is decided.

   Outcome

   Every round-3 fix holds. The permission inventory, the trust gaps and the asymmetries all checked out against the code and against v4-core's actual hook dispatch. Build was green after installing the three gitignored dependencies, and the 14 unit tests pass here. The fork tests need Sepolia and were not run.

   Low, CreatorFeeHook.recycle, line 270. The firstCredit clock has a mirror-image side effect. Once a pool's first unclaimed credit is 7 days old, recycle folds the whole balance, including credits from the same block, through the split. For an active coin whose flywheel module nobody pulls for a week, anyone can send the holders' entire weekly slice to the pot with 25 to 40 percent to the platform. I reproduced it on a local PoolManager: a 2 JIG stale balance plus a 3,939 JIG same-block credit were recycled together. No attacker profits, and pull() is permissionless, so the keeper pulling weekly is a full mitigation. The fix I propose keeps two buckets per ledger entry and recycles only the one older than 7 days.

   Info. The _converting flag is dead code, because v4's Hooks.afterSwap returns before calling the hook when the hook itself is the swapper. The protection is real but comes from the PoolManager, not the flag. Second Info: launch re-reads the fee after paying the platform, so a platform contract that changes the fee inside its receive strands the creator's refund in the factory, which has no withdraw path. Cache the fee at the top of launch.

   Round-3 questions and threat model

   • seal before seeding or skipped: No. Both are factory-only and happen in one launch call with no untrusted external call between register and seal. The collection is only staticcalled, and the airdrop notify, dev buy and refund all run after the seal.
   • factory seed blocked by the lock: No. The seal is set after the mint, and the pool cannot exist before register, so nobody can pre-seal or pre-seed.
   • refund reentrancy or griefing: No fund impact. launch is nonReentrant, a reverting creator only reverts their own launch. See the Info on the platform's receive.
   • firstCredit across epochs: Correct. A claim bumps the epoch, the next credit resets the entry and its clock. The side effect is the Low above.
   • hook callable in wrong order: No. beforeInitialize needs registration, seal needs registration, register is one-shot per pool id, and setFactory/setDeepening are owner one-shots.
   • (a) LP positions: Locked. JIGLaunch, CoinFactory and LPDeepening have no transfer, approve or decrease path, only a zero-liquidity decrease that collects fees. Contracts cannot sign the position permit.
   • (b) PotVault and AirdropClaim: Yes, only via declared or merkle distributions. The owner authors the trees, which is a documented trust assumption.
   • (c) supply: Cannot increase, both tokens are fixed-mint and burnable only.
   • (d) Vesting: Cannot be claimed early or redirected. Unused in production.
   • (e) JIGLaunchHook: Nobody gets the low fee without a proof for tx.origin, the fee is an LP fee and the only LP during the window is JIGLaunch. beforeSwap is view and only reverts on malformed hookData from the swapper. It cannot brick the pool.
   • (f) privileges: No privilege takes user funds beyond the documented ones. The keeper's min-out values bound sandwich loss. The hook owner can bind the 2 percent deepening slice once. The platform sets the launch fee.
   • Scope B: Fee arithmetic is exact for both orderings and both swap directions, exact-output sells are refused, split sums equal the fee, 10 percent on 1e27 fits comfortably in int128. ERC-6909 JIG claims always equal totalClaimable. Nobody can claim another's balance. The nested sale is bounded to the seeded range

   • lowrecycle() sweeps a flywheel's entire balance, including same-block credits, once its first credit is 7 days oldsrc/CreatorFeeHook.sol:270

     Round 3 moved the staleness clock from Earned.lastCredit to Earned.firstCredit so a dust buy cannot keep a stale balance alive. The side effect is the mirror image: once the FIRST unclaimed credit on a pool is RECYCLE_AFTER old, recycle() takes e.amount in full (line 271), and e.amount includes every credit since, down to one made in the same block.

     For an actively traded coin whose flywheel module (HolderDrip, SnapshotForwarder, BuybackAndBurn, SweepAndBurn) has not been pulled for 7 days, anyone can fold the whole flywheel slice earned in those 7 days through the split: platformBps (25-40%) to the platform, 3% pot, 2% deepening and the rest to the pot.

     None of that JIG is 'lost' money: the modules' pull() is permissionless and the keeper is meant to call it, so the only party that gains is the platform, which is also the party that runs the keeper. The same applies to the creator's own slice (recycled to the flywheel), but that is the creator's own inaction.

     Severity Low: no attacker profit, holders' flywheel slice is redirected to platform/pot only when nobody (holders included) calls pull() for a week; the README documents recycling but not that fresh credits are swept with the stale ones. Fix (minimal, keeps the design): keep two buckets per Earned entry, e.g. {uint128 stale; uint128 recent; uint64 recentSince}.

     In _creditEarned: if (block.timestamp >= recentSince + RECYCLE_AFTER) { stale += recent; recent = 0; recentSince = now; } recent += amount. In recycle(): roll the same way, then require stale > 0 and recycle only stale, leaving recent untouched.

     Alternative policy fix: exempt contract flywheels from recycle (their pull() is permissionless so their balance can never be orphaned) and recycle only creator balances. Operational mitigation until then: the keeper must pull every module at least weekly.

     whole finding

     Local harness (test/scratch/RecycleFresh.t.sol; this test contract acts as the factory; needs FOUNDRY_OPTIMIZER_RUNS=44444 because the repo's via-ir/800-runs profile cannot compile a local PoolManager, no config change).

     Pool coin/JIG at 1:1, fee 1%, flywheel = an address F, default split. t0 (after the snipe window): buyer swaps 1,000 JIG exact-input -> claimable[F] = 2.0019e18 (stale). warp(t0 + 7 days + 1 s): buyer swaps 1,000,000 JIG -> F credited a further 3.9392e21 in the same block.

     Then anyone calls hook.recycle(key, F).

     Expected (what the README's 'unclaimed for RECYCLE_AFTER' implies): 2.0019e18 recycled, the fresh 3.9392e21 stays with F.

     Actual: recycle() returns 3,941,201,868,487,893,266,331 wei (= stale + fresh), claimable[F] == 0, claimable[platform] grows by 25% of the fresh credit (~985 JIG), pot by ~2,955 JIG.

     Assertion assertEq(recycled, stale) fails with 3941201868487893266331 != 2001960280243146605.

     whole reproduction

   • info_converting guard is dead code: v4 never calls afterSwap for the hook's own nested swapsrc/CreatorFeeHook.sol:339

     Hooks.afterSwap in v4-core (lib/v4-periphery/lib/v4-core/src/libraries/Hooks.sol line 293) returns before calling the hook whenever msg.sender == address(self), and the nested conversion in _sellCoinForJig is a poolManager.swap() made by the hook itself.

     So afterSwap is never re-entered during the conversion, the branch at line 339 is unreachable, and the fee-skip / double-credit protection the comment and the threat model attribute to _converting actually comes from the PoolManager. Not a vulnerability (the outcome is correct either way), but the storage write/clear costs ~5k gas per coin-fee swap and the reasoning in the README/round reports should cite the v4 self-call rule, not the flag.

     Same rule applies to beforeAddLiquidity (noSelfCall): the seal would not bind a modifyLiquidity call made by the hook itself, which the hook has no code path for; keep it that way.

     Fix: delete _converting and its three uses, or keep it and correct the comments.

     whole finding

     Any exact-input buy on a creator pool after launch (e.g. the scratch harness above: 1,000 JIG in). afterSwap runs once, calls poolManager.swap() for the fee coin; set a breakpoint or emit in afterSwap: it is entered exactly once per outer swap, never with _converting == true. Static: Hooks.sol:293 if (msg.sender == address(self)) return (swapDelta, BalanceDeltaLibrary.ZERO_DELTA);.

   • infolaunch() re-reads launchFeeWei after the platform's receive, so a fee change inside that call strands the creator's refund in the factorysrc/CoinFactory.sol:164

     The round-3 refund path compares msg.value with the storage variable launchFeeWei twice (lines 164 and 166-167) after an external call to the platform.

     If the platform is a contract whose receive() (or anything it calls) invokes setLaunchFee(), the second read differs from the first: with msg.value 0.015 ETH and fee 0.01 raised to 0.015 during receive, the platform is paid 0.01, msg.value > launchFeeWei is false, and 0.005 ETH stays in CoinFactory forever (the factory has no withdraw and no receive, so it is unrecoverable by anyone). Raising it above msg.value gives the same result.

     The platform is a trusted role and gains nothing, so this is Info, but it is the only path by which ETH can be stuck in the factory and it is a one-line fix: cache uint256 fee = launchFeeWei; at the top of launch() and use it for the check, the payment and the refund.

     Deploy CoinFactory with platform = a contract whose receive() calls factory.setLaunchFee(0.015 ether); launchFeeWei = 0.01 ether.

     Creator calls launch{value: 0.015 ether}(...).

     Expected: platform receives 0.01, creator refunded 0.005.

     Actual: platform receives 0.01, creator refunded 0, address(factory).balance == 0.005 ether permanently.

4. Audit mathAgent #1215found 5 info

   The review is complete and the findings file is written and validated.

   Result: nothing above Info remains. Every round-3 fix holds, and the math, boundary and numerical-gap passes over the whole base found only dust-level artefacts. The findings file at .imd-findings.json holds five Info entries, each with a concrete input, and no Critical, High, Medium or Low.

   How the round-3 questions came out

   • seal ordering: seal is factory-only, needs register first, and the factory calls it in the same launch transaction right after seeding. Liquidity adds revert both before register and after seal. The factory's own mint runs in between, and the pool id includes the hook, so nobody can pre-initialise or front-run the seed.
   • launch refund: launch is nonReentrant and both ETH pushes come after all state writes. A reverting caller only breaks its own launch.
   • firstCredit: verified on a fork. A second credit at day 3 left the clock at the first credit, recycle at day 7 moved the full earned amount with the 70/25/5 split, and after a claim the next credit restarted the clock and recycle reverted NotStale.
   • hook call order: only register before seal and seal before liquidity are order-sensitive, and both are enforced.

   Fee arithmetic measured on a Sepolia fork at a 1% fee, coin as currency0, 900M coin seeded single-sided:

   Swap	Paid	Fee credited
   exact-input buy, 1000 JIG	980,932 coin out	10.011 JIG
   exact-output buy, same coin	1002.17 JIG in	10.022 JIG
   exact-input sell, all coin	1962.3 JIG out	19.82 JIG

   heldJig equalled totalClaimable after every swap, recycle and claim, and the four claimable balances summed to totalClaimable. A buy from below the range converted its fee with pendingCoin staying at zero.

   The Info items recorded

   • A sub-wei coin fee on a dust buy converts to zero JIG while the buyer still loses the coin.
   • HolderDrip strands fewer than live wei per pull in its accounted total.
   • register checks the flywheel against the deepening address bound at that moment, so a launch before setDeepening can name the future LPDeepening. No value is extractable.
   • recycle re-splits with the current platform band rather than the band in force when earned, so after lowerFee the platform receives less on recycling.

   Threat-model items A through C are answered yes/no with reasoning inside the first finding's description. The L2 notes from round 3 stand unchanged.

   Housekeeping: the scratch harness was removed, dependencies live only in the gitignored lib/, and the working tree shows no stray files. The local PoolManager would not compile under the project's optimizer settings, so the probe ran against the Sepolia PoolManager on a pinned fork block instead, as the repository's own tests do.

   • infoRound-4 result: every round-3 fix holds and nothing above Info was found in the math, boundary and numerical-gap passessrc/CreatorFeeHook.sol:255

     Plain statement for the swarm-phase decision: after a genuine pass over the whole base with the Math Precision, Boundary and Numerical Gap guides, plus the round-3 regression questions, no defect above Info remains.

     Verified on a Sepolia fork with a local harness (test contract acting as factory, hook deployed at a 0x2844-flagged address, pool seeded through PoolModifyLiquidityTest, PoolSwapTest swaps): (1) seal ordering: seal() is factory-only, register() must precede it (NotRegistered) and the factory calls it in the same launch() transaction immediately after _seed, so no window exists in which a pool is registered but open; beforeAddLiquidity reverts LiquidityLocked both before register (unregistered id) and after seal, and the factory's own mint passes because it runs between the two; the factory's seed cannot be front-run because the pool id includes the hook and beforeInitialize requires the registered flag, which only the factory can set.

     (2) Launch refund: launch() is nonReentrant and both ETH pushes happen after all state writes; a reverting msg.sender only reverts its own launch; a reverting platform blocks every launch but the platform is the trusted team wallet.

     (3) firstCredit across epochs: a second credit at day 3 left firstCredit at the first credit (1792139315), recycle at day 7+ moved 10.0109 JIG as 70% flywheel / 25% platform / 5% pot+deepening; after claim() the epoch moves on, the next credit resets firstCredit to the credit time and recycle reverts NotStale.

     (4) Hook call order: register before seal, seal before any liquidity, afterSwap requires registered, beforeInitialize requires registered; nothing else is order-sensitive.

     Fee arithmetic measured at feePips=10_000 after the snipe window, coin as currency0 at tick -69000 with 900M coin single-sided: exact-input buy of 1000 JIG paid 10.0109 JIG (1.0011% because the coin fee is sold at the post-trade price), exact-output buy of the same 980,932 coin cost 1002.17 JIG with 10.0217 JIG fee (f/(1-f) scaling gives the same rate), exact-input sell paid 19.82 of 1962.3 JIG (1.01%). heldJig == totalClaimable held after every swap, recycle and claim, and claimable(creator)+claimable(fly)+claimable(platform)+claimable(pot) == totalClaimable.

     After a sell drove the price to MIN_SQRT_PRICE+1 (below the range), a buy converted its fee with pendingCoin staying 0.

     Threat-model answers: A(a) no: JIGLaunch, CoinFactory and LPDeepening only ever call modifyLiquidities with MINT/INCREASE/DECREASE(0)+TAKE_PAIR and hold no approve/transfer path for the ERC-721; A(b) no: PotVault and AirdropClaim move tokens only to proven leaves or the pot; A(c) no: JIG and CreatorCoin mint once in the constructor; A(d) no: Vesting has no revoke or redirect and release pays only the stored beneficiary; A(e) no: the 1.5% needs a proof for tx.origin, the only revert in beforeSwap is the swapper's own malformed hookData; A(f) no new path, the keeper's self-sandwich within minOut and the sweeper buying its own listing at the cap remain the documented residual trust.

     B(a) no: both directions pay rate f, exact-output sells are refused; B(b) no: _converting is set only around the nested swap and only afterSwap reads it, no other code runs during the nested swap; B(c) no: totalClaimable == heldJig is maintained by _split, recycle and _claim, and claimFor pays only the credited address; B(d) price impact of the conversion is borne in the fee recipients' favour (buyer-side), partial fills are retried from pendingCoin; B(e) all setters are owner/factory/creator gated and one-shot where stated; B(f) currentFee is bounded in [feePips, 600_000] with a divisor of 10, no overflow; B(g) the five slices sum exactly to the fee (flywheel is the remainder) and 10% on a 2^90-scale output is far below int128; B(h) 0x2844 and 0x2880 match the permission structs and validateHookPermissions runs in both constructors.

   • infoCreatorFeeHook.afterSwap: a sub-wei coin fee is taken from the buyer but converts to zero JIG, so dust buys pay nothing to the recipients while still losing the coinsrc/CreatorFeeHook.sol:399

     Boundary x precision seam. For an exact-input buy the fee is f of the coin output, which is then sold into the same pool. When fee * price < 1 wei of JIG the nested swap consumes the coin (owed > 0) but returns jigDelta == 0, so _split(c, 0) credits nobody and the swapper has still lost the coin.

     The fee itself is also floored to zero when the output is below PIPS/feePips wei (99 wei at 1%).

     Both are dust: at 18 decimals the buyer would need to split a trade into sub-1000-wei pieces, and gas makes that worthless. Reported so the behaviour is documented; no fix needed.

     Same harness as above, after the price is inside the range at tick about -69000 (1 coin = 0.001 JIG): exact-input buy of 50 wei JIG.

     Expected (naively) a 1% fee credit; actual totalClaimable delta is 0 while the buyer received about 49,500 wei coin instead of 50,000 (the 500 wei coin fee was taken by the hook and either sold for 0 wei JIG or parked as pendingCoin).

     Observed in the probe log as 'dust buy fee delta 0'.

   • infoHolderDrip.pull strands up to live-1 wei per pull in 'accounted' that no token can ever claimsrc/HolderDrip.sol:83

     Precision x invariant seam. accPerToken grows by floor(amount1e18/live) but accounted grows by the full amount, so the remainder amount - floor(amount1e18/live)live/1e18 (less than live wei, since ACC = 1e18 only absorbs the division when amount1e18 is divisible by live) is counted as distributed yet is owed to nobody. undistributed() excludes it, so it is never re-spread and sits in the contract forever.

     Magnitude is below the live supply in wei per pull, so for a 10,000-token collection a lifetime of 1,000 pulls strands at most 1e7 wei of JIG. No fix required; if wanted, track the distributed amount as (acc delta * live) / ACC instead of amount.

     HolderDrip with live = 3 and 10 wei of JIG undistributed: pull() sets accPerToken += 3333333333333333333 (floor(10e18/3)), accounted += 10. Each token can claim floor(3333333333333333333/1e18) = 3 wei, 9 wei in total; 1 wei remains in the contract with accounted - paidOut == 1 after all three claims and undistributed() == 0, so no later pull can re-spread it.

   • infoCreatorFeeHook.register checks the flywheel against the deepening address bound at registration time, so a coin launched before setDeepening can name the future LPDeepening as its flywheelsrc/CreatorFeeHook.sol:173

     Temporal boundary. Until setDeepening() runs, deepening == pot, so the BadFlywheel check only excludes the pot. The deploy order is hook, factory, then LPDeepening (DeployDeepening.s.sol binds it afterwards), and the LPDeepening address is a plain CREATE address predictable from the deployer nonce.

     A launch in that gap with flywheel == the future LPDeepening passes register().

     Consequence: that pool's flywheel slice is credited to LPDeepening and its stale balance can be recycled by anyone to pot/deepening/platform (the flywheel side's remainder goes to the pot), never to the recycler, and LPDeepening.pull() is permissionless, so no value is extractable. It only defeats the stated intent of the list.

     Fix if wanted: have the factory refuse launches while hook.deepening() == hook.pot(), or have register() also reject flywheel == factory.platform-style module addresses once bound; cheapest is a one-line check in CoinFactory.launch.

     whole finding

     Deploy hook and factory, do not call setDeepening.

     Compute the LPDeepening address the deployer will create next (keccak(rlp(deployer, nonce))). launch({... flywheel: thatAddress ...}) succeeds (expected: BadFlywheel, actual: PoolRegistered with flywheel == thatAddress).

     Then setDeepening(thatAddress) succeeds and every swap on that pool credits LPDeepening both the 2% deepening slice and the flywheel block.

   • infoCreatorFeeHook.recycle splits with the platform band of the current feePips, not the band in force when the balance was earnedsrc/CreatorFeeHook.sol:278

     Economics x asymmetry seam, tiny. _split() credits the platform by the band of the fee at swap time; recycle() re-splits the stale creator or flywheel balance by the band of the fee at recycle time. After lowerFee() from the 7-10% band (platform 4000) to the 1% band (platform 2500), a stale balance earned under the old band pays the platform 25% instead of 40% on recycling, with the difference going to the flywheel (creator's stale money) or the pot (flywheel's stale money).

     The recycler never gains and the creator cannot raise the fee, so the only direction is less to the platform. Documented as an accepted asymmetry or fixed by storing the band with the Earned entry.

     Pool registered at feePips 100_000 (platform 4000).

     Creator earns 100 JIG on a swap (platform was credited 40 of the 100-fee at swap time).

     Creator calls lowerFee(key, 10_000).

     Seven days later anyone calls recycle(key, creator): expected under the earning band plat = 40; actual plat = (100 * 2500) / 10_000 = 25, flywheel receives 100 - 3 - 2 - 25 = 70 instead of 55.

5. Audit economicsAgent #595found 1 medium, 1 low

   The findings file is written and validated, the scratch tests are removed, and the tree is clean. Here is the report.

   Outcome

   Two findings survived verification and are in .imd-findings.json: one Medium, one Low. Nothing Critical or High. All 62 existing tests pass on a Sepolia fork (17 Regressions, 10 CreatorCoin, 9 JIGLaunchHook, 8 Flywheels, 14 unit). Every round-3 fix holds. The swarm phase is not quite clean: the Medium is a magnitude the round-3 Info item #4 understated by two orders of magnitude.

   Findings

   Medium. Exact-input buys pay the fee at the marginal post-trade price (src/CreatorFeeHook.sol:365). The fee coin is sold back from the price the buyer's own trade just set, so the JIG recovered is the cost of the last 1% of coin they bought, not 1% of what they paid. Measured on the fork at the standard launch with a 1% fee, exact-input versus exact-output for the same coin:

   JIG spent	share of pool	exact-input fee	exact-output fee
   100k	9%	1.10%	0.99%
   1M	50%	2.00%	0.99%
   10M	90%	10.2%	0.99%
   300M	buy-out	75.7%	0.99%

   On the buy-out, 227M of 300M JIG goes to fee recipients and 73M stays in the pool backing the coin. Routers default to exact-input, so this is the launch-sniper path, and 70% of the inflated fee is credited to the creator. Proposed fix: sell the fee coin exact-output for f × JIG input and return only the coin actually used as the hook delta, or move the buy fee to the JIG input side with a before-swap return delta.

   Low. The round-3 launch refund lets a fee front-run capture the whole overpayment (src/CoinFactory.sol:122). A creator sending 0.5 ETH against a 0.01 ETH fee pays 0.5 ETH if the platform raises the fee first. Before round 3 that reverted. Fix: a maxFeeWei in the launch params.

   Round-3 fixes, verified

   • seal before seed or skipped: No. Only the factory calls it, after its own mint in the same transaction. There is no path that registers without sealing.
   • Factory seed blocked by the lock: No. The pool is registered, initialised, seeded and sealed atomically, so no one can add liquidity in between.
   • Launch refund reentrancy or griefing: No. The call is guarded, runs after all state, and only the overpaying caller can revert it.
   • firstCredit across epochs: Correct. An epoch change resets the ledger before the zero-amount check, and a recycle leaves the amount at zero so the next credit restarts the clock.
   • Hook callable out of order: No. Seal on an unregistered pool reverts, seal is idempotent, and unregistered pools cannot be initialised.

   Threat model answers

   • (a) LP positions locked: Yes. No transfer or decrease function exists, and the holders cannot produce EIP-1271 signatures for permit.
   • (b) PotVault and AirdropClaim exits: Yes, only through merkle claims or sweeps to the pot.
   • (c) Supply fixed: Yes, neither token has a mint path.

   • (e) JIGLaunchHook: Yes, the proof is checked against tx.origin per swap. Malformed hookData reverts only that swap, so the hook cannot brick the pool.
   • (f) Privileged powers: Trust assumptions only, plus the Low above. Owner-set merkle roots, keeper min-out, and market approval are documented.
   • Scope B: No swap pays less than the fee. The converting guard has no untrusted callback inside it. Claim accounting holds, with totalClaimable equal to held JIG in every probe including a full buy-out and sell-back. Access control and flag bits are correct and validated in the constructor.
   • Scope C: HolderDrip's checkpoints are correct for LoomCollection's 1-based monotone supply. SweepAndBurn, BuybackAndBurn and LPDeepening unlock callbacks are PoolManager-only and settle exact deltas. AirdropClaim is per-coin isolated.

   • mediumExact-input buys pay the 1-10% fee at the marginal post-trade price: 2x nominal at half the pool, 10x at 90%, 76x on a buy-out, while exact-output pays exactly fsrc/CreatorFeeHook.sol:365

     For an exact-input buy (JIG in, coin out) afterSwap takes f of the gross coin output and _sellCoinForJig sells that coin back into the same pool starting from the price the buyer's own trade just left (sqrtPriceLimit = range bottom, exact-input, no cap). The JIG recovered is the cost of the LAST f*G coin the buyer bought, i.e. the marginal segment of their own price impact, not f of what they paid.

     On the single-sided launch position every launch-sized buy has real price impact, so the fee the buyer actually loses in JIG grows without bound with trade size.

     Measured on a Sepolia fork at the repo's standard launch (1 JIG = 1000 coin, 950M coin seeded, 1% fee, snipe window over): exact-input 1k JIG -> 1.00%; 100k JIG (9% of pool) -> 1.10%; 1M JIG (50% of pool) -> 2.00%; 10M JIG (90% of pool) -> 10.19%; 50M -> 34.5%; 100M -> 51.1%; 300M (buy-out, 937M coin) -> 75.7%: 227M of the 300M JIG paid is credited to creator/platform/pot/deepening and only 73M stays in the pool backing the coin.

     Buying the same 937M coin with an exact-output swap costs 73.7M JIG and pays 0.99%. Exact-output buys (fee charged on the JIG input, line 351) pay the nominal rate in every case, so the two swap kinds price the same trade up to 4x apart. The buyer is not an attacker and receives exactly the quoted coin, so a router quote shows nothing wrong; the loss is that the pool keeps 73M instead of 300M JIG, which is all their coin can ever be sold back for.

     'Pay X' router flows are exact-input by default, so this is the common path for a launch sniper or a large first buyer, and 70% of the inflated fee is credited to the creator (flywheel = 0) and 25% to the platform. Round 3 (#4) recorded the direction ('above nominal, by construction') as Info without the magnitude; the magnitude makes the stated 1-10% fee band untrue for any trade with price impact, which on a fresh single-sided pool is every meaningful trade.

     Fix (minimal, keeps the 'fee in the unspecified currency, held as JIG' design): bound the conversion to the nominal JIG value.

     In afterSwap when feeIsCoin: target = (|specified JIG input| * feePips) / PIPS; run the nested sale as EXACT-OUTPUT for target JIG (amountSpecified = +int256(target), same price limit); read coinUsed from the delta; mint JIG claims for the JIG received; return int128(coinUsed) instead of fee as the hook delta so the fee coin that was not needed stays with the swapper; fall back to coin claims / pendingCoin only when the price sits at the range edge and nothing can be sold.

     Cleaner alternative: take the buy fee on the JIG input with BEFORE_SWAP + BEFORE_SWAP_RETURNS_DELTA (return +f*amountIn on the specified currency) and drop the nested conversion entirely; that changes the hook flags/address and needs a redeploy.

   • lowlaunch() refund introduced in round 3 lets a setLaunchFee front-run capture the creator's whole overpaymentsrc/CoinFactory.sol:122

     Round 3 changed launch() from an exact-fee check to msg.value >= launchFeeWei with the excess refunded (lines 166-169), so a creator who pads msg.value to survive a fee update (the stated reason for the change) now has no upper bound on what they agree to pay: the fee charged is whatever launchFeeWei is when the transaction executes, up to msg.value.

     The platform (the only caller of setLaunchFee) can raise the fee to msg.value in the same block, or an honest fee update that lands first silently consumes the padding. Before round 3 an unexpected fee simply reverted the launch; now it is paid.

     The platform is a trusted role, so this is a trust-assumption and griefing note rather than a theft, but it is a regression the fix introduced: the rationale 'a fee update landing before a quoted launch must not revert it' is only safe when the creator can state the maximum they accept.

     Fix: add uint256 maxFeeWei to LaunchParams, revert WrongFee when launchFeeWei > p.maxFeeWei (keep msg.value >= launchFeeWei and the refund of the difference). The front end passes the quoted fee plus its tolerance.

6. Audit judgeAgent #1357found 3 low, 5 info

   The findings file validates: eight findings, every snippet matches its line, no tracked file changed (only lib/, test/scratch/ and .imd-findings.json were created).

   Verdict

   Nothing above Low remains. Every round-3 fix holds. I reproduced every kept finding on a Sepolia fork with a scratch harness (test/scratch/Judge.fork.t.sol, 8 tests, all pass with the numbers quoted in the findings). The specialists' 12 reports collapsed to 8 findings: 3 Low, 5 Info. One specialist report (the "round-4 result" statement) was a summary, not a defect, and the dust-buy rounding note was dropped as behaviour, not a defect.

   Low

   • recycle() clock from firstCredit sweeps fresh credits with the stale one and lets recycle(creator) chain into recycle(flywheel) in the same block. Merged from two specialists. Reproduced: 10,014 JIG credited the same block was swept; the flywheel lost 11,016 JIG to the pot where the README says it should have been fed. This is the one behaviour the round-3 fixes made worse.
   • Exact-input buys pay the fee at the marginal post-trade price. Measured 200 bps at half the pool and 1019 bps at 90%, against 99 bps for exact-output buys of the same coin. Round 3 accepted the direction as Info; I rate the magnitude Low and leave the acceptance to Jj.
   • launch() has no caller-stated max fee since the refund change, so a setLaunchFee mined first takes the whole msg.value. Trusted role, but a new power under threat-model item (f). Reproduced: creator lost 0.5 ETH.

   Info: launchFeeWei re-read after the platform call strands a refund (0.005 ETH stuck); _converting is dead code because v4 skips afterSwap on self-calls (Hooks.sol:293); a pre-setDeepening launch can name the future LPDeepening as flywheel; recycle() uses the current fee band; HolderDrip strands under live wei per pull.

   Round-3 fix verification

   • seal() ordering: register, initialize, seed and seal all run inside one launch() transaction with no untrusted callback between them. beforeInitialize and beforeAddLiquidity both require registered, which only the factory sets, so the pool cannot be pre-initialised or front-seeded. Confirmed by test.
   • Launch refund: nonReentrant, both pushes after all state writes. A reverting msg.sender reverts only its own overpaid launch.
   • firstCredit across epochs: a claim bumps the epoch and the next credit starts a fresh clock. The repo's own regression test and my test confirm it. The side effect is the Low above.
   • Hook call order: nothing else is order-sensitive.

   Threat model answers

   • A(a) no: JIGLaunch, CoinFactory and LPDeepening only mint, increase, or decrease by zero; no transfer or approve path. A(b) no: PotVault and AirdropClaim move tokens only to proven leaves or the pot. A(c) no: both tokens mint once in the constructor. A(d) no: Vesting is irrevocable and pays only the stored beneficiary. A(e) no: the 1.5% needs a proof for tx.origin; the only revert in beforeSwap is the swapper's own malformed hookData. A(f) only the new setLaunchFee capture above, plus the documented keeper residuals.
   • B(a) no, both directions pay rate f at the nominal level and exact-output sells are refused; the price-impact Low is the caveat. B(b) no, and the real guard is v4's self-call rule. B(c) no: heldJig == totalClaimable held after every swap, recycle and claim in my tests, and claimFor pays only the credited address. B(d) impact falls on the buyer side, see the Low. B(e) all setters correctly gated and one-shot. B(f) bounded, no overflow. B(g) five slices sum exactly to the fee. B(h) 0x2844 and 0x2880 match the permission structs.
   • C(a) consistent, LP locked, both orderings handled. C(b) correct apart from the dust Info. C(c) keeper bounded by cap, approved market, and the JIG-outflow check; inflow tolerated. C(d) callbacks are PoolManager-only. C(e) owner powers are as documented. C(f) LoomCollection mints totalSupply + 1, supply is monotone, no burn: the a

   • lowrecycle() staleness runs from firstCredit, which never refreshes while a balance is outstanding: fresh credits are swept with the stale one, and recycle(creator) chains into recycle(flywheel) in the ssrc/CreatorFeeHook.sol:270

     Round 3 moved the recycle clock from Earned.lastCredit to Earned.firstCredit. _creditEarned (line 427) only sets firstCredit when e.amount == 0, so once ANY unclaimed credit on a pool is RECYCLE_AFTER old, recycle() takes e.amount in full (line 271), which includes every credit since, down to one made in the same block.

     Two consequences, both introduced by the round-3 change (merged from two specialists, same root cause, one fix): (1) for an actively traded coin whose flywheel (HolderDrip, SnapshotForwarder, BuybackAndBurn, SweepAndBurn) or creator has not pulled for 7 days, anyone can fold the WHOLE 7 days of earnings through the split, not just the stale part; the README (line 188) says a balance 'untouched for 7 days' is recyclable, which readers take to mean the stale money, not fresh fees.

     (2) recycle(creator) credits the creator's block to the flywheel via _creditEarned (line 283); since the flywheel's e.amount is already > 0 its firstCredit stays old, so recycle(flywheel) succeeds in the same transaction and the block that was meant to 'feed the flywheel' (README line 106) goes to the pot instead, with the platform/pot/deepening cut taken twice. Under the round-2 lastCredit rule the second call reverted NotStale.

     Nobody profits except the platform/pot; the losers are the flywheel's beneficiaries (NFT holders, buyback) and the creator.

     Severity Low: no attacker gain, needs a week of nobody calling the permissionless pull(), but it contradicts the documented recycle semantics and is the only behaviour the round-3 fix set made worse.

     Fix (keeps the design): track two buckets per Earned entry, e.g. {uint128 stale; uint128 recent; uint64 recentSince}: in _creditEarned, if block.timestamp >= recentSince + RECYCLE_AFTER then stale += recent, recent = 0, recentSince = now; then recent += amount. recycle() rolls the same way, requires stale > 0 and recycles only stale.

     And in recycle() credit the flywheel with _credit(fly, rest) instead of _creditEarned so recycled money is never re-recyclable (or set e.firstCredit = block.timestamp on that inflow). Operational mitigation until then: the keeper pulls every module at least weekly.

   • lowExact-input buys pay the fee at the marginal post-trade price: 2x nominal at half the pool, 10x at 90%, while exact-output buys of the same coin pay exactly fsrc/CreatorFeeHook.sol:365

     For an exact-input buy (JIG in, coin out) afterSwap takes f of the coin output and _sellCoinForJig sells that coin back into the same pool, exact-input with the range edge as the only limit, starting from the price the buyer's own trade just left. The JIG recovered is the cost of the LAST f*G coin the buyer bought (the marginal segment of their own price impact), not f of what they paid.

     On the single-sided launch position every launch-sized buy has real price impact, so the JIG the buyer effectively loses to the fee grows without bound with trade size, while exact-output buys (fee charged on the JIG input, line 351) pay the nominal rate at every size.

     The buyer receives exactly the quoted (1-f)*G coin, so a router quote shows nothing wrong; the loss shows up as the pool keeping far less JIG than the buyer paid, which is all their coin can ever be sold back for, and as the creator (70%) and platform (25%) being credited many multiples of the stated fee.

     Round 3 (#4) recorded the direction ('above nominal, by construction') as Info without the magnitude; measured here it makes the stated 1-10% band untrue for any trade above about 10% of the pool.

     Severity Low: no third party can trigger it, the buyer is not an attacker, and it was accepted as a design property in round 3; reported because the magnitude at realistic launch-sniper sizes (50% of pool -> 2x, 90% -> 10x) was not on the table when it was accepted.

     Fix (keeps the 'fee in the unspecified currency, held as JIG' design): bound the conversion to the nominal JIG value: target = (|specified JIG input| * feePips) / PIPS; run the nested sale as EXACT-OUTPUT for target JIG (amountSpecified = +int256(target), same price limit); read coinUsed from the delta; mint JIG claims for the JIG received; return int128(coinUsed) as the hook delta so the coin not needed stays with the swapper; fall back to pendingCoin only when the price sits at the range edge.

   • infolaunch() re-reads launchFeeWei from storage after paying the platform, so a fee change inside the platform's receive() strands the creator's refund in the factorysrc/CoinFactory.sol:166

     The refund path compares msg.value with the storage variable launchFeeWei (lines 164, 166, 167) after an external call to the platform. nonReentrant guards launch() but not setLaunchFee().

     If the platform is a contract (a Safe with a module or fallback handler, for example) whose receive() calls setLaunchFee(), the second read differs from the first: with msg.value 0.015 ETH and the fee raised from 0.01 to 0.015 (or anything >= msg.value) during receive, the platform is paid 0.01, msg.value > launchFeeWei is false, and 0.005 ETH stays in CoinFactory forever (no withdraw, no receive, nothing can ever move it).

     Lowering it instead makes the refund larger than the factory holds and the launch reverts. The platform is trusted and gains nothing, so Info (merged from two specialists), but it is the only path by which ETH can be stuck in the factory and the fix is one line: cache uint256 fee = launchFeeWei; at the top of launch() and use fee for the check, the platform payment and the refund.

   • info_converting is dead code: v4 never calls afterSwap for the hook's own nested swap, so the fee-skip protection comes from the PoolManager, not the flagsrc/CreatorFeeHook.sol:339

     So afterSwap is never re-entered during the conversion, the branch at line 339 is unreachable, and the double-charge / double-credit protection the README ('guarded by _converting so the nested swap is not charged again', line 193) and the threat model attribute to _converting is actually the PoolManager's self-call rule.

     Not a vulnerability (the outcome is correct either way); the two storage writes cost about 5k gas per coin-fee swap and the README's reasoning should cite the v4 rule. The same noSelfCall rule means a seal would not bind a modifyLiquidity call made by the hook itself; the hook has no such code path and must not gain one.

     Fix: delete _converting and its three uses, or keep it as belt-and-braces and correct the comments.

Dynamic: any exact-input buy on a creator pool after launch (test/scratch/Judge.fork.t.sol::test_F4, 1,000 JIG in) enters afterSwap exactly once per outer swap; a require(!_converting) placed at line 339 never fires.

   • inforegister() checks the flywheel against the deepening address bound at registration time, so a coin launched before setDeepening can name the future LPDeepening as its flywheelsrc/CreatorFeeHook.sol:173

     Until setDeepening() runs, deepening == pot, so the BadFlywheel list excludes only the pot. The deploy order is hook, factory, then LPDeepening (DeployDeepening.s.sol binds it afterwards), and the LPDeepening address is a plain CREATE address predictable from the deployer nonce. A launch in that gap with flywheel == the future LPDeepening passes register(), and setDeepening() to that address later succeeds.

     Consequence: that pool's flywheel slice is credited to LPDeepening and its stale balance is recyclable by anyone to pot/deepening/platform (the flywheel side's remainder goes to the pot), never to the recycler, and LPDeepening.pull() is permissionless, so no value is extractable; it only defeats the stated intent of the exclusion list.

     Fix if wanted: have CoinFactory.launch refuse launches while hook.deepening() == hook.pot() (one line), or have setDeepening refuse an address already registered as a flywheel.

     whole finding

     Sepolia fork (test/scratch/Judge.fork.t.sol::test_F6).

     Deploy hook and factory, do not call setDeepening. launch({... flywheel: X ...}) with X = the address LPDeepening will get.

     EXPECTED: BadFlywheel.

     ACTUAL: PoolRegistered with pools[id].flywheel == X; then vm.prank(owner); hook.setDeepening(X) succeeds and hook.deepening() == X, so every swap on that pool credits X both the 2% deepening slice and the flywheel block.

   • inforecycle() re-splits with the platform band of the current feePips, not the band in force when the balance was earnedsrc/CreatorFeeHook.sol:278

     _split() credits the platform by the band of the fee at swap time; recycle() re-splits the stale creator or flywheel balance by the band of the fee at recycle time. After lowerFee() from the 7-10% band (platform 4000) to the 1% band (platform 2500), a stale balance earned under the old band pays the platform 25% instead of 40% on recycling, with the difference going to the flywheel (creator's stale money) or the pot (flywheel's stale money).

     The recycler never gains and the creator cannot raise the fee, so the only direction is less to the platform. Accept and document, or store the band with the Earned entry.

     Sepolia fork (test/scratch/Judge.fork.t.sol::test_F7).

     Pool registered at feePips 100_000 (platform band 4000).

     After the snipe window a 1,000 JIG exact-input buy credits the creator 55050656338532086231 (55.05 JIG).

     Creator calls lowerFee(key, 10_000). warp +7 days + 1 s; anyone calls recycle(key, creator).

     EXPECTED under the earning band: platform credited 40% = 22.02 JIG.

     ACTUAL: platform credited 13762664084633021557 = exactly 25% (55.05 * 2500 / 10_000).

   • infoHolderDrip.pull() books the full amount as distributed but the accumulator floors, so up to live-1 wei per pull is owed to nobody and never re-spreadsrc/HolderDrip.sol:83

     accPerToken grows by floor(amount*1e18/live) but accounted grows by the full amount (line 84). The remainder, less than live wei per pull, is counted as distributed yet is claimable by no token. undistributed() = balance - (accounted - paidOut) excludes it, so it is never re-spread and sits in the contract forever.

     Magnitude is below the live supply in wei per pull (a 10,000-token collection strands at most 1e4 wei per pull), so no fix is required; if wanted, grow accounted by (accDelta * live) / ACC instead of amount so the remainder stays undistributed and is picked up by the next pull.

     Sepolia fork (test/scratch/Judge.fork.t.sol::test_F5).

     HolderDrip on a collection with 3 live tokens; transfer 10 wei of JIG to it; pull(): accPerToken += 3333333333333333333, accounted += 10.

     The holder claims ids 1..3: EXPECTED all 10 wei eventually distributable.

     ACTUAL: claim returns 9, jig.balanceOf(drip) == 1, undistributed() == 0, so no later pull can ever re-spread the 1 wei.
