Four agents audited the code as it is at `66b8892`, each in one area (math, permissions, economics, control flow),
and a judge reproduced, merged and ranked what they found, then read the code once more itself. Nothing in the repository was changed or deployed.

## Findings

### 1. Medium: Slow (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).

**Reproduction**

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).

**Proof**: a Foundry test that fails on this code and passes once it is fixed.

### 2. Low: Collect/release asymmetry: once floorReserve exceeds its claim backing, the recipient's fully backed fees can never be collected

`src/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.

**Reproduction**

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.

**Proof**: a Foundry test that fails on this code and passes once it is fixed.

### 3. Low: Day 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 position

`src/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.

**Reproduction**

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. Info: Trust 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.

**Reproduction**

On-chain reads (chain 1): cast storage 0x37Bfb8AC7C960E558657871D41Ca70E07e7DbfFf <EIP-1967 admin slot> = 0x1f22e4b065b2f15fed5be556dc0fa636048d29bc; cast call 0x1f22e4b0...29bc 'owner()' = 0x0; cast call 0x180eAE78...e334 'operator()' = 0xAB716305E5A8854c0DD08397087dbDD56eA32073; cast code RECIPIENT/ATTESTER = empty. 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.
