• 1.mediumSlow (84h) average is stepped with the raw receipt gap, so one receipt after a quiet period of up to 2 days moves emaLong by up to ~18%src/DynamicSellFloorProgram.sol:303

              l = _ema(o.emaLong, target, dt, TAU_LONG);

  Root cause: in _observe the short average is rate-bounded (MAX_STEP_BPS_PER_HOUR, MAX_STEP_BPS), but once oracleWarm is true the long average is updated as _ema(emaLong, target, dt, TAU_LONG) with dt = ts - lastTime. The only bound on dt is the reseed rule (more than STALE_AFTER = 2 days forces a reseed). The weight is dt/(dt+TAU_LONG), so after a 47h gap the new (already 50%-moved) short target gets 169200/471600 = 35.9% of the weight. The pool price only changes when trades happen, so during the gap the price was the OLD one. This update treats the new price as if it had held for the whole gap. The NatSpec at lines 30-31 and 175 calls this a slow average with a 3.5-day time constant. averagePrice() returns emaLong, and both quote (via _extraAt, lines 137-142) and the floor trigger (_inDrawdown, line 357) use it. Impact:

  1. After a quiet period, one buy that pushes the price up raises emaLong by up to ~18%. Later large sells at the old price level are charged deficit = (1.179-1)/1.179 = 15.2% and so pay the full MAX_EXTRA of 2.7% for about a day. The true week-long average has not moved, so this overcharges sellers.
  2. The mirror case: one sell lowers emaShort to 0.505P while emaLong only falls to 0.822P. That puts the program in drawdown from a single receipt, and releaseFloor can then move RELEASE_MAX per hour from the reserve. A smaller move scales down: after a 12h gap, one +50% receipt moves emaLong by 6.25%. Preconditions: the oracle is warm; there is no receipt with at least 0.01 ETH notional for 1-2 days (common in a thin pool); then one trade lands whose execution price is far from the last recorded one. No privilege is needed. The money goes to floorReserve/BURN_HOOK and is not stolen, but users pay fees outside the specified behaviour. Fix that keeps the design: bound the long step the same way the short one is bounded, for example l = _ema(o.emaLong, target, min(dt, 1 hours), TAU_LONG), or apply a per-hour cap in bps. Verified: with dt clamped to 1 hours the attached test passes (emaLong = 1.0059P).

  whole finding

  State: oracle warm at P = 1e15 (26 hourly buy receipts of 1 ETH at price exactly P); oracle.emaShort = oracle.emaLong = 1e15.

  Input: 47h later, one onTrade buy receipt {buy:true, amount0:-2e18, amount1:1000e18 (execution price 2e15), timestamp:now}.

  Expected: emaLong stays within a few percent of 1e15.

  Actual: emaShort = 1500000000000000, emaLong = 1179389312977099 (+17.9%), and sellExtra(sqrtPriceX96 for spot 1e15) = 27000 = MAX_EXTRA instead of ~0.

  Mirror input (verified): sell receipt {buy:false, amount0:1e18, amount1:-2000e18} 47h after warm-up gives emaShort = 505263157894737, emaLong = 822498995580555 and sets drawdownSince = block.timestamp.

  The proof fails on the current code with 'slow average jumped on a single receipt: 1179389312977099 > 1050000000000000' and passes when the long step uses min(dt, 1 hours).

• 2.lowCollect/release asymmetry: once floorReserve exceeds its claim backing, the recipient's fully backed fees can never be collectedsrc/DynamicSellFloorProgram.sol:254

          if (IFloorClaims(POOL_MANAGER).balanceOf(address(this), 0) < amount + floorReserve) revert CollectInvalid();

  Two guards on the same id-0 claim balance give opposite priorities. _maybeRelease (lines 370-373) protects the recipient: each release is capped at held - pending. collectFees (line 254) protects the reserve: it requires held >= amount + floorReserve, so the recipient can be paid only while the WHOLE floorReserve is backed.

  If floorReserve ever exceeds held - pending, releases (permissionless; in stale mode they need no price condition) drain the reserve's real claims until held == pending. From then on _maybeRelease returns 0 (line 372). No other code path lowers floorReserve, so it stays above zero for good, and every collectFees call (manual or the automatic _maybeCollect) reverts CollectInvalid.

  Recovery needs someone to donate the shortfall in id-0 claims.

  Reachability: a shortfall needs a receipt whose moduleFeeEth is larger than the claims delivered for it. That happens if the GOVERNANCE-selected adapter under-delivers or sends a malformed receipt, or if DRAW_FUNDING.fund / BUY_HODL.fund ever re-entered sweepSurplus before _afterTrade did its accounting.

  In the live delivery model I checked (mainnet tx 0x168b56b03143e01d08830059626058c810f250f55cd4731484659028a0d06d84) the adapter transfers the claims in the same transaction, just before onTrade. The trigger is therefore a trusted-adapter fault, and that is why the severity is low. The defect is that the program's own recovery path deadlocks instead of absorbing the shortfall on the reserve side.

  Fix that keeps the design: since releases already never touch pending, collectFees should require only held >= amount + min(floorReserve, held - pending) (or held >= amount).

  Verified: with that guard the attached test passes.

  whole finding

  Draw and Buy & Hodl windows closed (warp 1_800_000_000).

  PoolManager, GOVERNANCE and DRAW are mocked at their constant addresses.

  The program holds 0.7 ETH of id-0 claims.

  The adapter delivers a sell receipt {id:1, amount0:10 ether, amount1:-1e24, moduleFeeEth:1.2 ether}, which gives recipientAccrued = 0.02 ether and floorReserve = 1.18 ether.

  The automatic collect is deferred because 0.7 < 0.02 + 1.18.

  Then releaseFloor() is called every 3 days, 40 times: the held balance falls to 0.02 ether while floorReserve stays at 0.5 ether.

  Expected: collectFees(0.02 ether) pays RECIPIENT.

  Actual: it reverts CollectInvalid, and it keeps reverting because floorReserve can no longer decrease.

  The test fails with CollectInvalid() on the current code and passes with the min(floorReserve, held - pending) guard.

• 3.lowDay 7 size gate and execution-price estimate use the swap-time in-range liquidity, which a seller can inflate for one swap with a just-in-time positionsrc/DynamicSellFloorProgram.sol:103

          if (!isLargeSell(amountSpecified, sqrtPriceX96, liquidity)) return a; // Day 7

  quote classifies a sell as LARGE by comparing it with a virtual reserve computed from the liquidity argument (isLargeSell, lines 111-121). sellExtraFor/executionPrice (lines 148-166) also assume that same liquidity. In Uniswap v4 a seller can add a narrow position around the current tick, swap, and remove the position inside one unlock. Flash accounting settles the net, so no capital stays locked.

  With 20x the in-range liquidity, a 100 CLAUS sell that is 9.5% of the honest reserve reads as 0.47%: isLargeSell returns false and quote returns the 0.2% baseline instead of 2.9%. The narrow range is crossed during the swap, so most of the sell still hits the honest liquidity. The seller really does sell most of the size to the market while skipping the extra.

  Severity is low: the header (lines 22-24) already discloses that the gate is per swap and can be avoided by splitting a sell, and that the execution price assumes the current in-range liquidity. This is a second bypass at a similar cost (two liquidity calls instead of N swaps). It also relies on an assumption: the pool's hook must allow arbitrary liquidity adds and removes.

  Nothing in this repository restricts that, but the hook's code was not available.

  Who loses: floorReserve, and with it the Buyback & Burn hook. Fix (needs a design decision): gate on a quantity the seller cannot inflate for a single transaction. Examples are an ETH-notional threshold, or min(current liquidity, a liquidity value the program tracks from receipts).

  Use the same quantity in executionPrice. Otherwise, add this bypass to the disclosed limits.

  whole finding

  State: oracle warm with emaLong = 1e18 (13 buy receipts of 1 ETH / 1 CLAUS, 150 min apart).

  Input A: quote(any, false, -100e18, uint160(2^96*105409/100000) [spot 10% below average], 1000e18, "").

  Result: a[5] = 29000 (A5 + MAX_EXTRA).

  Input B: the same call with liquidity = 20000e18, which is the in-range liquidity after a +-0.3% JIT position is added in the same unlock.

  Expected: a[5] = 29000.

  Actual: a[5] = 2000, because isLargeSell(-100e18, sqrtP, 20000e18) is false (100e18 <= 21082e18*50/10000).

  The proof fails on the current code with 'extra must not vanish because of transient in-range liquidity: 2000 != 29000'.

• 4.infoTrust assumptions: privileged roles and mutable dependencies that can change behaviour after review (adapter selection, receipt contents, receipt ids, BURN_HOOK, DRAW, ATTESTER)src/ClausDrawFundingProgram.sol:42

          if (msg.sender != authority.adapterFor(address(this)) || !authority.approvedAdapter(msg.sender))

  Coverage: I read src/DynamicSellFloorProgram.sol (the entry file), its base src/ClausDrawFundingProgram.sol and src/IClausTradeProgram.sol in full. Behaviour: quote returns the fixed allocation. Hyperdrive raises a[4] when rolling 24h volume is at least 75 ETH. A LARGE sell below the warm slow average adds up to 2.7% to a[5]. onTrade (only the GOVERNANCE-selected, approved adapter) checks the receipt, forwards the draw and Buy & Hodl shares, and then updates volume, oracle, floor reserve, recipient accrual, keeper state, releases and auto-collect. Not covered: the adapter, dispatcher, hook and PoolManager sources are not in the tree. Facts about them below come from on-chain reads at block ~26334065 and are stated as such. These items are trust assumptions, not bypasses. No unprivileged path moves ETH anywhere except RECIPIENT or BURN_HOOK.

  1. GOVERNANCE 0x180eAE78...e334 is a contract with no EIP-1967 slots; its operator() is EOA 0xAB716305...2073. It is read live on every onTrade (line 42), so it can switch the adapter at any time. The program checks only id uniqueness, module == msg.sender, dataHash == keccak256(data) and timestamp <= block.timestamp (line 44). Every other field is trusted as given: amounts, buy flag, feeEth, moduleFeeEth. No minimum timestamp is enforced, so receipts never expire. The program also never checks that moduleFeeEth claims arrived, so an adapter that under-delivers creates unbacked floorReserve/recipientAccrued (and see the collectFees lock finding). Verified live delivery: operator EOA -> dispatcher 0xea043646...7f91 -> adapter 0x71a8f53e...d069 (adapterFor(0xfad1...) == adapter, approvedAdapter == true). In that delivery the adapter transfers the id-0 claims in the same tx, just before onTrade, and the claims the program received are 0.2% of amount0 (the dispatcher receipt says 0.3%; the adapter keeps the 0.1% compute share). For a base-fee sell, floorShare therefore comes out at 0 wei after rounding.
  2. Receipt ids are keyed by id alone (drawReceiptConsumed, buyTime, keeper chain). A replacement adapter whose ids overlap with earlier ones (for example, after A delivered id 5, B delivers its own id 5) is rejected with DrawFundingInvalidReceipt. Any claims sent for that receipt then become sweepable surplus. The header discloses this limit.
  3. BURN_HOOK 0x37Bfb8AC...bfFf receives every release (line 379) and sweep (line 327). It is an EIP-1967 transparent proxy: implementation 0xa62f9b59...ce14, admin 0x1f22e4b0...29bc, an OZ ProxyAdmin. That ProxyAdmin's owner() currently returns address(0), so ownership is renounced, and the implementation has no upgradeTo/upgradeToAndCall selectors. The specialist's claim that the admin can redirect claims is therefore not true as of this block. The NatSpec still calls it upgradeable.
  4. DRAW 0xF54c2f80...f0A0: startedAt()/endsAt() are read live in quote (base line 36), onTrade (base line 49) and floorShare (line 221). Their live values are 1793200595 and 1793805395, so the window is open now. If DRAW changes these values or reverts, the draw deduction and floor attribution change, or quote/onTrade revert. DRAW_FUNDING and BUY_HODL are non-proxy contracts that receive an external fund() CALL before accounting. I assume they do not re-enter; their source was not reviewed.
  5. ATTESTER 0x8aCA8890...4cFa (an EOA) alone decides keeper wallets, ordering and the scan watermark. RECIPIENT 0x5a428Ea2...d995 is an EOA. If either later adopts EIP-7702 code, re-entry during take() hits the _payment guard and finds accounting already updated.

  Adapter switch: if GOVERNANCE sets adapterFor(program) = B and approves B, then B calling onTrade({id: unused, module: B, buy:false, amount0:1e21, amount1:-1e21, moduleFeeEth:1e20, timestamp:1, dataHash:keccak256("")}, "") with the windows closed succeeds without sending any claims. floorReserve + recipientAccrued rise by 1e20 with nothing backing them.

  Id overlap: after adapter A has delivered id 5, B's receipt with id 5 reverts DrawFundingInvalidReceipt.

1. Posted6 minto the first attempt
2. Audit permissionsAgent #832found 1 low, 3 info

   I found no access-control bypass in the permissions review. There is one low-severity defect, confirmed with a failing Foundry test, plus three trust-assumption notes. All four are in .imd-findings.json with their quoted code lines checked against the source. I changed no files in the repository.

   Files read (all fully readable, nothing missing):

   • src/DynamicSellFloorProgram.sol: the entry file.
   • src/ClausDrawFundingProgram.sol: the base contract. It holds quote and onTrade, the caller check and the replay guard, and it sends the fee shares for the draw and the Buy & Hodl competition.
   • src/IClausTradeProgram.sol: the shared receipt type and interface.
   • The external contracts (PoolManager, the governance contract, the draw and funding contracts, the burn hook) are not in the repository. I read their deployed bytecode and storage slots on-chain, but not their source.

   What the code does: quote adds an extra seller fee of up to 2.7% on large sells while the price is below a slow average. onTrade takes the draw and Buy & Hodl cuts and records volume for the busy-day bonus. It updates a rate-limited price average, splits the remaining fee between the fixed recipient (recipientAccrued) and the floor reserve (floorReserve), and runs the "keeper of the keys" logic. Anyone may call collectFees, sweepSurplus, releaseFloor and crownKeeper; each pays only a fixed address. Only ATTESTER, a plain wallet, can call the attest* functions.

   Checked and holding:

   • unlockCallback only accepts PoolManager during this contract's own payment.
   • The same receipt id cannot be processed twice.
   • Releases never spend the claims backing the recipient's unpaid fees.
   • The recipient is a plain wallet, so paying it out cannot re-enter the contract.
   • The keeper invalidation and crowning paths matched their stated rules.

   Findings:

   1. Low: the recipient's fees can be locked for good (DynamicSellFloorProgram.sol:254). The release path protects the recipient's share, but collectFees requires floorReserve to be fully backed. If the reserve is ever larger than its backing, releases drain the backing to zero and collectFees reverts from then on. In the test: 0.7 ETH of claims for a receipt reporting 1.2 ETH, then 40 releases. That leaves exactly the 0.02 ETH owed to the recipient, and collectFees(0.02 ether) reverts with CollectInvalid.
      • A shortfall like this needs either a misbehaving adapter or a funding contract that re-enters sweepSurplus mid-onTrade.
      • The fix is to require only held >= amount in collectFees, since releases already protect the recipient. The attached test passes once that is done.
   2. Info: governance can swap the adapter at any time (ClausDrawFundingProgram.sol:42). The selected adapter fully controls fee accounting, the price average, the busy-day bonus and keeper state. Receipts never expire because the timestamp has no lower bound.
   3. Info: the replay guard is keyed by trade.id only (ClausDrawFundingProgram.sol:44). A replacement adapter whose ids overlap the old one's will have those receipts rejected. The code comments already disclose this.
   4. Info: BURN_HOOK is an upgradeable proxy (DynamicSellFloorProgram.sol:71). On-chain its admin is 0x1f22…29bc and its implementation is 0xa62f…ce14. Every floor release and surplus sweep goes there, so that admin decides what happens to the money.

   What is assumed, not verified:

   • That the adapter delivers exactly moduleFeeEth worth of claims before calling onTrade. The adapter and governance source is not in the repository.
   • That ETH amounts in receipts are gross of fees.
   • The economic attacks (manipulating the price average, splitting sells to avoid the extra fee) belong to other review areas and got only a light look.

   The repository has no foundry.toml or lib/forge-std, so I ran the test in a temporary copy under /tmp using an existing forge-std. Its source is in the fi

   • lowRecipient's backed fees become permanently uncollectable once floorReserve exceeds its claim backing (collect/release asymmetry)src/DynamicSellFloorProgram.sol:254

     Two guards on the same PoolManager ETH claim (id 0) balance give different priorities. _maybeRelease (L370-373) protects the recipient: it caps each release at held - pending, so the recipient's pending claims are never sent to BURN_HOOK. collectFees (L254) does the opposite and requires held >= amount + floorReserve, so the recipient can be paid only when the whole floorReserve is backed.

     If floorReserve ever exceeds held - pending, releases keep draining the reserve's real claims until held == pending. After that floorReserve stays above zero and can never shrink: _maybeRelease returns 0 at L372, and no other function decreases floorReserve. collectFees then reverts for every amount, so the recipient's fully backed fees are locked for good. A shortfall like this cannot come from an outside caller alone.

     It needs a receipt whose moduleFeeEth is larger than the claims delivered for it. Two ways that can happen: (a) the governance-selected adapter credits too little or sends a malformed receipt, because floorShare/recipientAccrued are derived only from receipt fields; or (b) DRAW_FUNDING.fund or BUY_HODL.fund re-enters and calls sweepSurplus during onTrade.

     In that window (ClausDrawFundingProgram.sol L55/L64, before _afterTrade adds the trade to accounting), the unaccounted module fee counts as surplus. Fix that keeps the design: since release already protects the recipient, collectFees should require only held >= amount, or held >= amount + min(floorReserve, held - pending). It should not require full backing of floorReserve.

     whole finding

     Draw and Buy & Hodl windows closed (warp 1_800_000_000).

     PoolManager, GOVERNANCE and DRAW are mocked at their constant addresses.

     The program holds 0.7 ETH of id-0 claims.

     The adapter delivers a sell receipt with id=1, amount0=10 ether, moduleFeeEth=1.2 ether, which gives recipientAccrued=0.02 ether and floorReserve=1.18 ether.

     Then call releaseFloor() once every 3 days (stale mode) 40 times.

     The held balance falls to 0.02 ether (exactly pending), and floorReserve stays at 0.5 ether. collectFees(0.02 ether): expected success, paying RECIPIENT.

     Actual: reverts CollectInvalid, and keeps reverting forever because floorReserve can no longer decrease.

     Verified with the attached test (fails with CollectInvalid on the current code).

   • infoTrust assumption: GOVERNANCE can switch the receipt-supplying adapter at any time; the new adapter fully drives fee accounting, oracle, hyperdrive and keeper statesrc/ClausDrawFundingProgram.sol:42

     onTrade's only caller check reads GOVERNANCE (0x180e...e334, verified on-chain as a contract with no EIP-1967 implementation or admin slot set) on every call.

     Every value used afterwards comes from the receipt, and the receipt is not bound to anything the program can check on-chain: amount0/amount1 feed the oracle and hyperdrive volume, moduleFeeEth and feeEth feed floorReserve and recipientAccrued, timestamp feeds the windows, staleness and keeper times, and buy feeds the keeper hall of fame. dataHash only binds data to the receipt, not the receipt to a real swap. timestamp has an upper bound but no lower bound, so receipts never expire.

     Whoever controls GOVERNANCE's adapter selection can therefore change the program's behaviour after this review without any change to the program.

     Examples: inflating floorReserve without backing (which leads to the lock in the previous finding), seeding or moving the oracle to trigger floor releases, or crowning arbitrary keeper reigns together with the ATTESTER. This is the stated design, but it is a material trust assumption.

     whole finding

     GOVERNANCE.adapterFor(program) is changed to adapter B, and B is approved.

     B calls onTrade with {id: unused, module: B, buy: false, amount0: 1e21, moduleFeeEth: 1e20, timestamp: 1} and data="" while the program holds enough claims for the base draw and Buy & Hodl transfers (zero outside those windows).

     Result: floorReserve and recipientAccrued increase by 1e20 in total with no backing claims.

     No check in the program rejects the receipt, and its timestamp of 1 is accepted (no expiry).

   • infoReceipt replay guard is keyed by trade.id only, so a replacement adapter with an overlapping id space has its receipts rejectedsrc/ClausDrawFundingProgram.sol:44

     drawReceiptConsumed, buyTime and the keeper chain are all keyed by trade.id alone, not by (module, id). Duplicate delivery from one adapter is correctly rejected. But after GOVERNANCE selects a new adapter whose ids restart or overlap, every overlapping receipt reverts with DrawFundingInvalidReceipt.

     Depending on how the adapter handles a revert, those trades are either blocked or dropped. Their module-fee claims would then be left unaccounted, where sweepSurplus sends them to BURN_HOOK instead of the recipient. The keeper attestation order (strictly increasing ids) is also broken by such a switch.

     The header comment discloses this limit. It is listed here because the task asks for every dependency change that alters behaviour.

     Adapter A delivers a receipt with id=5.

     GOVERNANCE switches to adapter B, which numbers receipts from 1.

     B's onTrade with id=5 (module=B, valid dataHash): expected acceptance as a new receipt; actual revert DrawFundingInvalidReceipt because drawReceiptConsumed[5] is true.

   • infoBURN_HOOK, the destination of every floor release and surplus sweep, is a mutable EIP-1967 proxysrc/DynamicSellFloorProgram.sol:71

     On-chain at review time, BURN_HOOK has implementation slot 0x360894... = 0xa62f9b597225779b430024398b70374e8468ce14 and admin slot 0xb53127... = 0x1f22e4b065b2f15fed5be556dc0fa636048d29bc. Anyone can call releaseFloor() or sweepSurplus(), and both push id-0 claims to this address: up to 0.05 ETH per hour of floorReserve, and all of the unreserved surplus.

     The proxy admin can upgrade the implementation and redirect those claims anywhere, for example instead of buying back and burning CLAUS. RECIPIENT (0x5a42...d995) and ATTESTER (0x8aCA...4cFa) were verified as code-less EOAs, so take() to RECIPIENT cannot re-enter. DRAW, DRAW_FUNDING and BUY_HODL have no EIP-1967 slots set, but onTrade calls them externally before accounting (see the first finding).

     cast storage 0x37Bfb8AC7C960E558657871D41Ca70E07e7DbfFf 0xb53127684a568b3173ae13b9f8a6016e243e63b6e8ee1178d6a717850b5d6103 returns admin 0x1f22e4b0...29bc.

     That admin upgrades the proxy to an implementation that forwards id-0 claims to itself.

     Then any call to releaseFloor() in drawdown or stale mode transfers up to 0.05 ETH of claims per hour to the upgraded hook.

     Expected: the claims are used for buyback and burn.

     Actual: whatever the admin's implementation chooses.

3. Audit economicsAgent #1465found 1 medium, 2 low, 1 info

   The review is complete. The findings file holds four substantiated findings and no tracked file was changed.

   Files read in full. The entry file src/DynamicSellFloorProgram.sol plus both imports it depends on, ClausDrawFundingProgram.sol (receipt gate, draw and Buy & Hodl deductions) and IClausTradeProgram.sol (Trade struct). No entry file was unreadable.

   What the contract does. A Uniswap v4 trade program for the ETH/CLAUS pool. The adapter chosen by GOVERNANCE delivers one receipt per swap through onTrade. The program records a fee-weighted price oracle, a 24h volume window (Hyperdrive), and splits the remaining module fee between a fixed RECIPIENT and a floor reserve. The quote adds up to 2.7% to the module share of a sell that is large relative to in-range liquidity and executes below the slow average. The reserve is released to the Buyback & Burn hook in capped hourly amounts during a sustained drawdown or in stale mode.

   Findings written to .imd-findings.json

   • Medium, line 103. The large-sell gate and the execution-price estimate both read the pool's instantaneous in-range liquidity. A seller adds a narrow just-in-time position before the swap and removes it after, inside one unlock, and the extra disappears. Verified: same oracle, same spot 10% under average, 100 CLAUS sell gives a[5] of 29000 with honest liquidity and 2000 with inflated liquidity. The attached proof test fails on current code for exactly that reason. This is a different, cheaper bypass than the documented splitting limit.
   • Low, line 325. sweepSurplus has no timing guard. If claims reach the program in one transaction and the receipt in a later one, anyone can sweep the fee to BURN_HOOK first and leave recipientAccrued unbacked, so collectFees reverts for that amount. Conditional on the adapter's delivery model, which I could not verify on chain.
   • Low, line 345. Stale mode releases the reserve with no price condition after any two days without a non-dust receipt, so a quiet period on a still-active program spends the reserve in a flat market and the simultaneous oracle reseed blocks normal releases for at least a day afterward.
   • Info, line 244. If receipts are delivered inside a swap, the automatic collection self-call always hits AlreadyUnlocked and only defers itself hourly. Manual collectFees still works, so no funds are at risk.

   Verified properties. Receipt binding is sound: id consumed before external calls, dataHash and module checks, future timestamps rejected. collectFees and unlockCallback only move ETH to the fixed RECIPIENT, the payment lock cannot be left set, and the three balance guards keep floorReserve and pending fees from spending each other's claims. Quote has no revert path besides the pinned base's draw view. Oracle manipulation after warm-up costs far more in fees than the 0.05 ETH per hour it could release, so it is not reported. On chain, RECIPIENT and ATTESTER have no code, BURN_HOOK is an EIP-1967 proxy with a separate admin, and the draw window is open until about Nov 4.

   Trust assumptions, not defects. GOVERNANCE can swap the adapter, and a malicious adapter can feed receipts that move the oracle or redirect fees between RECIPIENT and BURN_HOOK, but cannot pull claims past the balance guards. BURN_HOOK's admin can change what happens to released claims.

   Coverage gaps. Whether receipt amount0 is gross or net of fee is unknown, which affects a small observed-price bias and a dust-level misroute in floorShare; neither is reported. The Keeper of the Keys subsystem got only a light pass since it moves no value. Gas was measured at roughly 190k to 290k per receipt and 15k per quote with a mock manager, not against the live adapter.

   • mediumLarge-sell gate and execution-price estimate read instantaneous in-range liquidity, so a just-in-time position removes the Day 7 extra from any large sellsrc/DynamicSellFloorProgram.sol:103

     quote decides whether a sell is LARGE by comparing the swap amount with a virtual reserve derived from the liquidity argument (isLargeSell, lines 111-121), and sellExtraFor measures the deficit at an execution price that also assumes that same liquidity (executionPrice, lines 148-166). liquidity is the pool's in-range liquidity at quote time.

     Any swapper can raise it for exactly one transaction by adding a narrow position around the current tick before the swap and removing it afterwards inside the same PoolManager unlock; Uniswap v4 flash accounting settles both at the end, so no capital is locked and there is no exposure between blocks.

     With the inflated figure the sell is no longer LARGE, isLargeSell returns false and quote returns the 0.2% baseline, so the whole 0..2.7% extra that is supposed to fund floorReserve is skipped. Even if the gate were kept, executionPrice collapses to spot with inflated liquidity, which defeats the revision 4 change that measured the deficit at execution price.

     The documented limit only covers splitting a sell into many swaps (each paying base fee and gas); this bypass needs one swap and two liquidity calls. Verified with the attached test and with isLargeSell/executionPrice directly: for a 100 CLAUS exact-input sell at sqrtP = 1.0541*2^96 (spot 10% under a warm 1e18 average) isLargeSell(-100e18, sqrtP, 1000e18) is true and quote returns a[5] = 29000, while isLargeSell(-100e18, sqrtP, 20000e18) is false and quote returns a[5] = 2000.

     The deposit a +-0.3% range needs for the second figure is about 63 CLAUS plus 63 ETH (0.3% of the 21082 CLAUS virtual reserve); with tick spacing 1 it is about 1 CLAUS plus 1 ETH, and both come back when the position is removed.

     Who loses: floorReserve, so the Buyback & Burn hook and token holders; the seller keeps about 2.7% of a 90 ETH-notional sell (about 2.4 ETH) per bypass.

     Assumption flagged: the pool's hook allows arbitrary liquidity adds and removes; most v4 pools do and nothing in this file prevents it. Fix needs a design decision: gate LARGE on a quantity the seller cannot inflate transiently (for example a liquidity value the program tracks itself from receipts or the lower of current and tracked liquidity, or a fixed ETH-notional threshold) and use the same quantity in executionPrice; or disclose the bypass with the other known limits.

   • lowsweepSurplus has no timing guard: claims that arrive before their receipt can be swept to BURN_HOOK, leaving recipientAccrued and floorReserve unbackedsrc/DynamicSellFloorProgram.sol:325

     sweepSurplus (anyone) transfers every ETH claim above floorReserve + pending to BURN_HOOK. The accounting that makes a claim 'reserved' only happens in _afterTrade when the receipt is delivered, and onTrade never checks that the claims backing moduleFeeEth are actually present (the pinned base only reverts if a draw/hodl transfer fails).

     If the adapter credits the module fee claims to this contract in one transaction and delivers the receipt later (the file's own vocabulary of 'late-delivered' and 'undelivered' receipts, the blockNumber/timestamp fields and the timestamp <= block.timestamp check all point to asynchronous delivery), then between those two transactions anyone can call sweepSurplus and move the fee to BURN_HOOK.

     After delivery recipientAccrued and floorReserve rise with nothing behind them: collectFees reverts CollectInvalid for that amount forever, normal releases are capped by held - pending, and in the draw window the base transfer to DRAW_FUNDING reverts so the receipt cannot be delivered while the balance is short. A griefer who repeats the sweep every block redirects all of RECIPIENT's baseline fees to buybacks at only gas cost.

     Not reachable if the adapter transfers the claims and calls onTrade in the same transaction; this could not be verified on chain (the live adapter is selected by GOVERNANCE and its source is not in the tree), so the finding is conditional on the delivery model.

     Fix: have sweepSurplus only move claims that have been unaccounted for longer than a grace period (track held at last delivery), or restrict it to a role, or have onTrade reconcile held against the sum it accounts for.

     whole finding

     State: program holds 1 ether of claim id 0 from the adapter, floorReserve = 0, recipientAccrued = recipientCollected = 0, receipt not yet delivered.

     Call sweepSurplus() from any address: returns 1 ether, BURN_HOOK balance +1 ether, program balance 0.

     Then adapter delivers the sell receipt {amount0: 500 ether, amount1: -500 ether, feeEth: 10 ether, moduleFeeEth: 1 ether, timestamp: now} via onTrade: succeeds, recipientAccrued = 1 ether.

     Expected: RECIPIENT can collect 1 ether.

     Actual: collectFees(1 ether) reverts CollectInvalid (balanceOf 0 < 1 ether + 0).

     Scratch test test_sweepBeforeReceiptStrandsRecipientFees in test/scratch/Econ.t.sol reproduces this.

   • lowStale mode drains the whole floor reserve into buybacks after any two quiet days, with no drawdown and while the program is still the active onesrc/DynamicSellFloorProgram.sol:345

     The stated purpose of floorReserve is to be released 'during a real drawdown, or slowly once this program stops receiving trades'. releasable() treats any gap of STALE_AFTER (2 days) since the last non-dust receipt as 'stopped receiving trades' and then lets anyone release RELEASE_MAX every hour with no price condition at all (lines 345-346 skip _inDrawdown). A thin token can easily see two days without a >= 0.01 ETH trade.

     Once that happens the reserve is spent on buybacks in a flat market, 1.2 ETH per day, until a qualifying receipt arrives; nothing distinguishes a quiet weekend from a replaced program. The same two-day gap also marks the oracle stale, so the next receipt reseeds it and starts a new warm-up (>= 1 day, 12 observations): when selling resumes in a real drawdown the reserve may already be partly or fully gone and no normal-mode release can happen for at least a day.

     Flow seam: execution x first principles. Fix is a design decision: tie stale mode to an explicit replacement signal (for example GOVERNANCE.adapterFor(this) no longer being the delivering adapter), or use a much longer stale window, or keep a drawdown condition on the stale path.

     whole finding

     State: oracle warm at 1e18, one large sell receipt {amount0: 100 ether, amount1: -100e18, feeEth: 5 ether, moduleFeeEth: 2.9 ether} delivered at time T gives floorReserve = 2.7 ether; emaShort == emaLong (no drawdown, drawdownSince = 0).

     No receipts with amount0 >= 0.01 ether for 2 days.

     At T + 2 days + 1 hour anyone calls releaseFloor().

     Expected under the stated purpose: 0 (no drawdown, program still active).

     Actual: releasable() returns (0.05 ether, staleMode = true), releaseFloor() transfers 0.05 ether of claims to BURN_HOOK, and the same call succeeds again every hour until floorReserve is 0 (54 hours).

     Scratch test test_staleModeDrainsReserveWithoutDrawdown in test/scratch/Econ.t.sol reproduces this.

   • infoAutomatic fee collection can never succeed when receipts are delivered inside a PoolManager unlock; every attempt only pushes collectRetryAfter out by an hoursrc/DynamicSellFloorProgram.sol:244

     _maybeCollect calls this.collectFees, which calls PoolManager.unlock. Uniswap v4's unlock reverts with AlreadyUnlocked whenever the manager is already unlocked, which is the case if the adapter delivers the receipt synchronously from a swap hook. In that model the self-call always reverts, the catch branch sets collectRetryAfter = now + 1 hour and emits CollectionDeferred, and the cycle repeats forever: RECIPIENT is paid only when someone calls collectFees from outside a swap.

     No funds are at risk (collectFees is permissionless and the manual path works, verified in test_collectInsideUnlockAlwaysDeferred), but the automatic path is dead code in that model and each qualifying receipt spends the gas of the failed attempt. Together with the sweepSurplus note: exactly one of the two delivery models applies, and each has one of these two issues.

     Fix: skip the attempt when the manager reports it is unlocked (v4 exposes the Lock transient slot via exttload), or drop the automatic attempt and document manual collection.

     whole finding

     State: PoolManager unlocked (receipt delivered from the hook's swap callback), recipientAccrued - recipientCollected >= 0.01 ether after the receipt, collectRetryAfter <= now.

     Call: adapter -> onTrade(sell receipt with moduleFeeEth = 1 ether).

     Expected: 1 ether paid to RECIPIENT.

     Actual: unlock reverts AlreadyUnlocked, CollectionDeferred(id, 1 ether) emitted, collectRetryAfter = now + 1 hours, RECIPIENT.balance unchanged; the next attempt one hour later fails the same way.

     Scratch test test_collectInsideUnlockAlwaysDeferred in test/scratch/Econ.t.sol reproduces this with a mock manager whose unlock reverts while unlocked.

4. Audit mathAgent #368found 1 medium, 1 info

   Review complete. The findings file is written and validated, no source or configuration file was changed, and all scratch work lives under test/scratch/.

   Files read in full. src/DynamicSellFloorProgram.sol (the entry), and its two imports src/ClausDrawFundingProgram.sol and src/IClausTradeProgram.sol. The program is a Claus trade hook: quote returns a six-slot fee allocation, adding a Hyperdrive bump on busy days and a sell extra of up to 2.7% for large sells priced below a slow on-chain average. onTrade consumes a receipt once, deducts the draw and Buy & Hodl shares in the base contract, feeds an EMA oracle from the receipt's execution price, splits the module fee between a floor reserve and a fixed recipient, and releases capped amounts to the burn hook during drawdowns or staleness. Keeper-of-the-Keys bookkeeping is attester-driven and has no fee effect.

   Verified properties (math area, in depth).

   • No arithmetic panic in isLargeSell, executionPrice, spotPrice, sellExtraFor across the full input domain (2000-run fuzz each, including int256.min, zero liquidity, max uint160).
   • The execution-price formula matches the Uniswap v3/v4 average-price identity for both exact-input and exact-output sells. Spot round-trip error is under one part per million.
   • floorShare conserves the remaining fee exactly and is pro-rata within 2 wei both outside and inside the draw and Buy & Hodl windows. Small sells put nothing into the floor.
   • Hyperdrive window arithmetic is correct at every hour boundary tested, including the bucket-expiry subtraction.
   • Narrowing casts are bounded before use; the short EMA caps and the maxDelta == 0 floor behave as documented.

   Finding recorded (medium, with proof). The long average that quote and the drawdown trigger rely on is stepped with the raw receipt gap, bounded only by the 2-day reseed rule. One receipt after a 47-hour lull moves it by 17.9%, so a large sell at an unchanged spot pays the full 2.7% extra, and the mirror case arms floor releases from a single receipt. The proof test at test/scratch/LongEmaJump.t.sol fails on the current code and passes with a one-line clamp of the long step, confirmed on a patched copy.

   Info note recorded. sweepSurplus treats any unaccounted claim as surplus. If the adapter transfers fee claims before delivering the receipt in a separate transaction, anyone can sweep them to the burn hook. This is flagged as unverified because the adapter is outside the repository.

   Trust assumptions and coverage limits. The adapter at GOVERNANCE, the DRAW window contract, the upgradeable BURN_HOOK proxy, and the PoolManager were mocked, not read. Receipt amount semantics (gross ETH on sells, fee-exclusive ETH on buys) are taken from the code comments. Keeper attestation logic was read but not exercised beyond the math passes. No static analyzer was run; only Foundry tests via out-of-tree remappings.

   • mediumLong (slow) average steps with the raw receipt gap: one receipt after a sub-2-day lull moves emaLong up to ~18%, mispricing the sell extra and arming floor releasessrc/DynamicSellFloorProgram.sol:303

     The short average is rate-bounded (MAX_STEP_BPS_PER_HOUR = 25%/h, MAX_STEP_BPS = 50% per update), but the long average that quote and the floor trigger actually use (averagePrice() returns emaLong) is stepped with the unbounded receipt gap dt = ts - lastTime. dt is only limited by the reseed rule (ts > lastTime + STALE_AFTER = 2 days), so one receipt arriving up to 172800 s after the previous one weights the (already 50%-moved) short target by dt/(dt+TAU_LONG) = 172800/475200 = 36.4%.

     The documented intent (NatSpec lines 29-31 and 175: a slow average with a 3.5 day time constant, 'roughly a one-week average', valid only after rate-bounded warm-up) is that no single receipt can swing it.

     Concrete values (verified in the attached test): warm oracle at emaShort = emaLong = P = 1e15; no qualifying receipt for 47 h; one 2 ETH buy with execution price 2P. target = _ema(P, 2P, 169200, 1800) = 1.989P -> capped to 1.5P; l = _ema(P, 1.5P, 169200, 302400) = P + 0.5P*169200/471600 = 1.1794P.

     Effect 1 (seller overpays): a large sell quoted at the unchanged spot P gets deficitBps = (1.1794-1)/1.1794 = 1521 >= FULL_DEFICIT_BPS, so a[5] = 2000 + 27000 and the seller pays the full 2.7% extra into floorReserve although the market did not fall. The excess decays only with TAU_LONG (84 h), so large sells are mispriced for roughly a day.

     Effect 2 (false drawdown): the mirror case, one 1 ETH sell at 0.5P after 47 h, gives emaShort = 0.505P and emaLong = 0.8225P; 0.505e4 < 0.8225*8500 so _inDrawdown() is true and drawdownSince is set from a single receipt; after RELEASE_INTERVAL anyone can call releaseFloor() and move RELEASE_MAX = 0.05 ETH per hour of reserve to BURN_HOOK while the condition persists.

     Preconditions are ordinary: a pool that is quiet for 1-2 days (no receipt with >= 0.01 ETH notional) followed by one trade whose average execution price differs from the last recorded one; in a thin pool a 0.01-2 ETH trade is enough and the actor needs no privilege.

     Who loses: large sellers (2.7% extra on sells that are not below the real average) and, in the drop case, the floor reserve is spent while no sustained drawdown exists. Minimal fix preserving the design: bound the long step as the short one is bounded, e.g. use dtL = min(dt, 1 hours) (or a rate cap in bps per hour) in the oracleWarm branch: l = _ema(o.emaLong, target, dtL, TAU_LONG).

     With dtL = 1 h the same receipt moves emaLong by 0.5P*3600/306000 = 0.59%, and the attached test passes.

     Expected: emaLong stays within a few percent of 1e15 (slow 84 h time-constant average).

     Actual: oracle.emaLong = 1179389312977099 (+17.9%), oracle.emaShort = 1500000000000000.

     Then sellExtra(sqrtPriceX96 for spot 1e15, i.e. 2505423094262580766190032085) returns 27000 (MAX_EXTRA) instead of 0.

     Mirror input: buy = false, amount0 = 1e18, amount1 = -2000e18 at T + 169200 gives emaShort = 505263157894737, emaLong = 822498995580555 and drawdownSince = block.timestamp.

   • infosweepSurplus treats every unaccounted ETH claim as surplus, including fee claims delivered before their receipt is processedsrc/DynamicSellFloorProgram.sol:326

     sweepSurplus() is permissionless and sends held - (floorReserve + pending) to BURN_HOOK. floorReserve and recipientAccrued are only credited inside onTrade. If the adapter moves the module-fee claims (ERC6909 id 0) to this program in a transaction before it delivers the receipt (the program is described as receiving late-delivered receipts), then between those two transactions the claims are 'surplus' and anyone can sweep them.

     The later onTrade still credits floorReserve/recipientAccrued for the full moduleFeeEth, leaving them unbacked, and if the draw window is open the base contract's claim transfer at ClausDrawFundingProgram.sol:54 fails and the receipt reverts. This is NOT verified as reachable: the adapter is outside the repository and the claims may be transferred atomically with onTrade (in which case there is no window). Reported so the author can confirm the adapter's ordering.

     Assumed state: adapter transfers X wei of claim id 0 to the program at block N and calls onTrade for the matching receipt at block N+k (k >= 1).

     Input: any account calls sweepSurplus() at a block in (N, N+k).

     Expected: fee claims awaiting their receipt stay with the program.

     Actual: X wei is transferred to BURN_HOOK; the subsequent onTrade credits recipientAccrued/floorReserve by moduleFeeEth without backing (collectFees then reverts with CollectInvalid on the balance check, _maybeRelease clamps to held - pending).

     If the adapter transfers and calls onTrade in one transaction this input does not exist.

   That notification is housekeeping only: the first wide-range log query (40,000 blocks) was stopped by its background time limit. It is not needed. I reran the same query over a 1,500-block range in the foreground, which succeeded and identified the live program, adapter and delivery transaction used in the review. Nothing changes in the result.

   The review stands as reported: .imd-findings.json holds two info-level findings with validated paths, lines and snippets, no critical or high defect was found, and the scratch test under test/scratch/ passes and confirms the keeper re-buy behavior.

     Inventory of every actor and dependency whose later change alters this program's behavior. These are documented trust assumptions, not permission bypasses; none lets an unprivileged party move ETH anywhere other than the fixed RECIPIENT or BURN_HOOK.

     1. GOVERNANCE 0x180eAE78...e334 (mainnet, live operator() = EOA 0xAB716305...2073): adapterFor(address(this))/approvedAdapter (src/ClausDrawFundingProgram.sol:42) is the only caller check on onTrade. Whoever it points to supplies EVERY receipt field; the program verifies only id uniqueness, module == msg.sender, dataHash == keccak256(data) and timestamp <= block.timestamp (src/ClausDrawFundingProgram.sol:44). It never checks that moduleFeeEth claims actually arrived, so recipientAccrued and floorReserve are unbacked if an adapter under-delivers; collectFees then reverts on the balance check (line 254) and the auto-collect path burns up to 150k gas per delivery until the 1h backoff.
     2. The receipt deliverer (live: operator EOA -> dispatcher 0xea043646...7f91 -> adapter 0x71a8f53e...d069 -> program, verified in tx 0x168b56b0...d684, block 26332482) controls delivery timing and order: the oracle keeps only the first receipt per trade-second (line 277), lastActivity/stale-mode release depends on which receipts are delivered, Hyperdrive fails open to the base fee when deliveries lag more than one hour (line 437), and keeper contradictions depend on delivery order.
     3. BURN_HOOK 0x37Bfb8AC...bfFf is an upgradeable proxy that receives all floor releases (line 379) and surplus sweeps (line 327); an upgrade redirects every earmarked ETH claim.
     4. DRAW 0xF54c2f80...f0A0 startedAt()/endsAt() are read live (line 221 and base line 49); live values 1793200595..1793805395, so the window is open at review time and closes in about 28h; a later re-arm of the draw changes floorShare attribution and re-enables the draw deduction.
     5. ATTESTER 0x8aCA8890...4cFa (EOA, no code) alone decides wallets, ordering and the scan watermark of the Keeper game.
     6. RECIPIENT 0x5a428Ea2...d995 is an EOA with no code (verified), so the native take in unlockCallback cannot re-enter.

     whole finding

     State: GOVERNANCE calls its setter so that adapterFor(program) == A2 and approvedAdapter(A2) == true (A2 any contract GOVERNANCE approves).

     Input: A2 calls onTrade(Trade{id: 1, module: A2, buy: false, amount0: +1e18, amount1: -1e21, feeEth: 0, moduleFeeEth: 1e18, timestamp: block.timestamp, dataHash: keccak256("")}, "") WITHOUT transferring any ERC-6909 ETH claims first.

     Expected by a reader of the NatSpec: fee accounting is backed by claims.

     Actual: all checks pass (base lines 42-45), recipientAccrued += 1e18 with zero backing, oracle reseeds at price 1e15 (line 280), and every later collectFees(amount) reverts CollectInvalid at line 254 until 1e18 of surplus claims arrive.

     Repeating with 12 receipts spaced 2h apart over 1 day makes the oracle warm at any price the rate limits allow, so large-sell extras and drawdown releases follow A2's numbers.

     Only GOVERNANCE/the adapter can do this; it is the documented trust boundary and is reported for disclosure, not as an exploit.

   • infoKeeper reign is reset by a re-buy from the same wallet, although the NatSpec says only another buy ends itsrc/DynamicSellFloorProgram.sol:528

     Line 449-450 states 'The buyer of the most recent main-pool buy holds the keys. If 24 hours pass with no other buy, that reign is crowned'. _attestKeeper (line 528) and _keeperOnBuy (lines 490, 495) invalidate the previous reign on ANY later buy inside 24h, without comparing wallet to keeperOf[prev]. A keeper who adds to their position inside the 24h window loses the accumulated time and must hold for a fresh 24h from the new buy.

     If every buy is meant to reset the clock this is intended and the NatSpec should say so; if the same wallet keeping the keys is meant to keep its reign, the check should skip _contradict when wallet == keeperOf[prev] and let keeperCrownable treat same-wallet successors as non-ending. No funds are involved; this only affects the hall-of-fame record.

     State: buy id 10 delivered with timestamp T and attested as attestKeeper(10, W); scanThrough later advanced past T+24h.

     Input: the same wallet W buys again, receipt id 11 with timestamp T+23h is delivered (buyTime[11]=T+23h; _keeperOnBuy line 490 fires _contradict(10, 11) because T+23h < T+24h), then attestKeeper(11, W).

     Expected under the 'no other buy' wording: reign 10 of W still crownable at T+24h.

     Actual: reignInvalid[10] == true, crownKeeper(10) reverts KeeperNotReady, and W is crownable only via reign 11 at T+47h (if no buy at all happens meanwhile).

   • mediumSlow (84h) average is stepped with the raw receipt gap, so one receipt after a quiet period of up to 2 days moves emaLong by up to ~18%src/DynamicSellFloorProgram.sol:303

     Root cause: in _observe the short average is rate-bounded (MAX_STEP_BPS_PER_HOUR, MAX_STEP_BPS), but once oracleWarm is true the long average is updated as _ema(emaLong, target, dt, TAU_LONG) with dt = ts - lastTime. The only bound on dt is the reseed rule (more than STALE_AFTER = 2 days forces a reseed). The weight is dt/(dt+TAU_LONG), so after a 47h gap the new (already 50%-moved) short target gets 169200/471600 = 35.9% of the weight. The pool price only changes when trades happen, so during the gap the price was the OLD one. This update treats the new price as if it had held for the whole gap. The NatSpec at lines 30-31 and 175 calls this a slow average with a 3.5-day time constant. averagePrice() returns emaLong, and both quote (via _extraAt, lines 137-142) and the floor trigger (_inDrawdown, line 357) use it. Impact:

     1. After a quiet period, one buy that pushes the price up raises emaLong by up to ~18%. Later large sells at the old price level are charged deficit = (1.179-1)/1.179 = 15.2% and so pay the full MAX_EXTRA of 2.7% for about a day. The true week-long average has not moved, so this overcharges sellers.
     2. The mirror case: one sell lowers emaShort to 0.505P while emaLong only falls to 0.822P. That puts the program in drawdown from a single receipt, and releaseFloor can then move RELEASE_MAX per hour from the reserve. A smaller move scales down: after a 12h gap, one +50% receipt moves emaLong by 6.25%. Preconditions: the oracle is warm; there is no receipt with at least 0.01 ETH notional for 1-2 days (common in a thin pool); then one trade lands whose execution price is far from the last recorded one. No privilege is needed. The money goes to floorReserve/BURN_HOOK and is not stolen, but users pay fees outside the specified behaviour. Fix that keeps the design: bound the long step the same way the short one is bounded, for example l = _ema(o.emaLong, target, min(dt, 1 hours), TAU_LONG), or apply a per-hour cap in bps. Verified: with dt clamped to 1 hours the attached test passes (emaLong = 1.0059P).

     whole finding

     State: oracle warm at P = 1e15 (26 hourly buy receipts of 1 ETH at price exactly P); oracle.emaShort = oracle.emaLong = 1e15.

     Input: 47h later, one onTrade buy receipt {buy:true, amount0:-2e18, amount1:1000e18 (execution price 2e15), timestamp:now}.

     Expected: emaLong stays within a few percent of 1e15.

     Actual: emaShort = 1500000000000000, emaLong = 1179389312977099 (+17.9%), and sellExtra(sqrtPriceX96 for spot 1e15) = 27000 = MAX_EXTRA instead of ~0.

     Mirror input (verified): sell receipt {buy:false, amount0:1e18, amount1:-2000e18} 47h after warm-up gives emaShort = 505263157894737, emaLong = 822498995580555 and sets drawdownSince = block.timestamp.

     The proof fails on the current code with 'slow average jumped on a single receipt: 1179389312977099 > 1050000000000000' and passes when the long step uses min(dt, 1 hours).

   • lowCollect/release asymmetry: once floorReserve exceeds its claim backing, the recipient's fully backed fees can never be collectedsrc/DynamicSellFloorProgram.sol:254

     Two guards on the same id-0 claim balance give opposite priorities. _maybeRelease (lines 370-373) protects the recipient: each release is capped at held - pending. collectFees (line 254) protects the reserve: it requires held >= amount + floorReserve, so the recipient can be paid only while the WHOLE floorReserve is backed.

     If floorReserve ever exceeds held - pending, releases (permissionless; in stale mode they need no price condition) drain the reserve's real claims until held == pending. From then on _maybeRelease returns 0 (line 372). No other code path lowers floorReserve, so it stays above zero for good, and every collectFees call (manual or the automatic _maybeCollect) reverts CollectInvalid.

     Recovery needs someone to donate the shortfall in id-0 claims.

     Reachability: a shortfall needs a receipt whose moduleFeeEth is larger than the claims delivered for it. That happens if the GOVERNANCE-selected adapter under-delivers or sends a malformed receipt, or if DRAW_FUNDING.fund / BUY_HODL.fund ever re-entered sweepSurplus before _afterTrade did its accounting.

     In the live delivery model I checked (mainnet tx 0x168b56b03143e01d08830059626058c810f250f55cd4731484659028a0d06d84) the adapter transfers the claims in the same transaction, just before onTrade. The trigger is therefore a trusted-adapter fault, and that is why the severity is low. The defect is that the program's own recovery path deadlocks instead of absorbing the shortfall on the reserve side.

     Fix that keeps the design: since releases already never touch pending, collectFees should require only held >= amount + min(floorReserve, held - pending) (or held >= amount).

     Verified: with that guard the attached test passes.

     whole finding

     Draw and Buy & Hodl windows closed (warp 1_800_000_000).

     PoolManager, GOVERNANCE and DRAW are mocked at their constant addresses.

     The program holds 0.7 ETH of id-0 claims.

     The adapter delivers a sell receipt {id:1, amount0:10 ether, amount1:-1e24, moduleFeeEth:1.2 ether}, which gives recipientAccrued = 0.02 ether and floorReserve = 1.18 ether.

     The automatic collect is deferred because 0.7 < 0.02 + 1.18.

     Then releaseFloor() is called every 3 days, 40 times: the held balance falls to 0.02 ether while floorReserve stays at 0.5 ether.

     Expected: collectFees(0.02 ether) pays RECIPIENT.

     Actual: it reverts CollectInvalid, and it keeps reverting because floorReserve can no longer decrease.

     The test fails with CollectInvalid() on the current code and passes with the min(floorReserve, held - pending) guard.

   • lowDay 7 size gate and execution-price estimate use the swap-time in-range liquidity, which a seller can inflate for one swap with a just-in-time positionsrc/DynamicSellFloorProgram.sol:103

     quote classifies a sell as LARGE by comparing it with a virtual reserve computed from the liquidity argument (isLargeSell, lines 111-121). sellExtraFor/executionPrice (lines 148-166) also assume that same liquidity. In Uniswap v4 a seller can add a narrow position around the current tick, swap, and remove the position inside one unlock. Flash accounting settles the net, so no capital stays locked.

     With 20x the in-range liquidity, a 100 CLAUS sell that is 9.5% of the honest reserve reads as 0.47%: isLargeSell returns false and quote returns the 0.2% baseline instead of 2.9%. The narrow range is crossed during the swap, so most of the sell still hits the honest liquidity. The seller really does sell most of the size to the market while skipping the extra.

     Severity is low: the header (lines 22-24) already discloses that the gate is per swap and can be avoided by splitting a sell, and that the execution price assumes the current in-range liquidity. This is a second bypass at a similar cost (two liquidity calls instead of N swaps). It also relies on an assumption: the pool's hook must allow arbitrary liquidity adds and removes.

     Nothing in this repository restricts that, but the hook's code was not available.

     Who loses: floorReserve, and with it the Buyback & Burn hook. Fix (needs a design decision): gate on a quantity the seller cannot inflate for a single transaction. Examples are an ETH-notional threshold, or min(current liquidity, a liquidity value the program tracks from receipts).

     Use the same quantity in executionPrice. Otherwise, add this bypass to the disclosed limits.

     whole finding

     State: oracle warm with emaLong = 1e18 (13 buy receipts of 1 ETH / 1 CLAUS, 150 min apart).

     Input A: quote(any, false, -100e18, uint160(2^96*105409/100000) [spot 10% below average], 1000e18, "").

     Result: a[5] = 29000 (A5 + MAX_EXTRA).

     Input B: the same call with liquidity = 20000e18, which is the in-range liquidity after a +-0.3% JIT position is added in the same unlock.

     Expected: a[5] = 29000.

     Actual: a[5] = 2000, because isLargeSell(-100e18, sqrtP, 20000e18) is false (100e18 <= 21082e18*50/10000).

     The proof fails on the current code with 'extra must not vanish because of transient in-range liquidity: 2000 != 29000'.

   • infoTrust assumptions: privileged roles and mutable dependencies that can change behaviour after review (adapter selection, receipt contents, receipt ids, BURN_HOOK, DRAW, ATTESTER)src/ClausDrawFundingProgram.sol:42

     Coverage: I read src/DynamicSellFloorProgram.sol (the entry file), its base src/ClausDrawFundingProgram.sol and src/IClausTradeProgram.sol in full. Behaviour: quote returns the fixed allocation. Hyperdrive raises a[4] when rolling 24h volume is at least 75 ETH. A LARGE sell below the warm slow average adds up to 2.7% to a[5]. onTrade (only the GOVERNANCE-selected, approved adapter) checks the receipt, forwards the draw and Buy & Hodl shares, and then updates volume, oracle, floor reserve, recipient accrual, keeper state, releases and auto-collect. Not covered: the adapter, dispatcher, hook and PoolManager sources are not in the tree. Facts about them below come from on-chain reads at block ~26334065 and are stated as such. These items are trust assumptions, not bypasses. No unprivileged path moves ETH anywhere except RECIPIENT or BURN_HOOK.

     1. GOVERNANCE 0x180eAE78...e334 is a contract with no EIP-1967 slots; its operator() is EOA 0xAB716305...2073. It is read live on every onTrade (line 42), so it can switch the adapter at any time. The program checks only id uniqueness, module == msg.sender, dataHash == keccak256(data) and timestamp <= block.timestamp (line 44). Every other field is trusted as given: amounts, buy flag, feeEth, moduleFeeEth. No minimum timestamp is enforced, so receipts never expire. The program also never checks that moduleFeeEth claims arrived, so an adapter that under-delivers creates unbacked floorReserve/recipientAccrued (and see the collectFees lock finding). Verified live delivery: operator EOA -> dispatcher 0xea043646...7f91 -> adapter 0x71a8f53e...d069 (adapterFor(0xfad1...) == adapter, approvedAdapter == true). In that delivery the adapter transfers the id-0 claims in the same tx, just before onTrade, and the claims the program received are 0.2% of amount0 (the dispatcher receipt says 0.3%; the adapter keeps the 0.1% compute share). For a base-fee sell, floorShare therefore comes out at 0 wei after rounding.
     2. Receipt ids are keyed by id alone (drawReceiptConsumed, buyTime, keeper chain). A replacement adapter whose ids overlap with earlier ones (for example, after A delivered id 5, B delivers its own id 5) is rejected with DrawFundingInvalidReceipt. Any claims sent for that receipt then become sweepable surplus. The header discloses this limit.
     3. BURN_HOOK 0x37Bfb8AC...bfFf receives every release (line 379) and sweep (line 327). It is an EIP-1967 transparent proxy: implementation 0xa62f9b59...ce14, admin 0x1f22e4b0...29bc, an OZ ProxyAdmin. That ProxyAdmin's owner() currently returns address(0), so ownership is renounced, and the implementation has no upgradeTo/upgradeToAndCall selectors. The specialist's claim that the admin can redirect claims is therefore not true as of this block. The NatSpec still calls it upgradeable.
     4. DRAW 0xF54c2f80...f0A0: startedAt()/endsAt() are read live in quote (base line 36), onTrade (base line 49) and floorShare (line 221). Their live values are 1793200595 and 1793805395, so the window is open now. If DRAW changes these values or reverts, the draw deduction and floor attribution change, or quote/onTrade revert. DRAW_FUNDING and BUY_HODL are non-proxy contracts that receive an external fund() CALL before accounting. I assume they do not re-enter; their source was not reviewed.
     5. ATTESTER 0x8aCA8890...4cFa (an EOA) alone decides keeper wallets, ordering and the scan watermark. RECIPIENT 0x5a428Ea2...d995 is an EOA. If either later adopts EIP-7702 code, re-entry during take() hits the _payment guard and finds accounting already updated.
