Nothing in the repository was changed or deployed. ## Findings ### 1. Medium: Oracle validity is time-based, so a single off-market seed (first receipt, or first receipt after a 2-day gap) survives warm-up and charges MAX_EXTRA plus releases floorReserve at an unchanged market `src/DynamicSellFloorProgram.sol:134` ``` if (uint256(o.lastTime) < uint256(o.seededAt) + MIN_COVERAGE) return (false, 0); ``` averagePrice() treats the oracle as valid once one observation lands MIN_COVERAGE (1 day) after seededAt (line 134); it never checks that the rate-bounded short average has converged or that more than one observation exists. The seed path (line 238) writes a single receipt's execution price into both averages with no bound, both at first use and whenever the previous observation is older than STALE_AFTER (line 236). Every later update is capped at MAX_STEP_BPS (50% of emaShort, lines 245-247) regardless of elapsed time, and during warm-up the long average simply copies the capped short average (line 252). So one seed far from the market followed by one honest receipt a day later yields a 'valid' long average still far above spot: with a 10x seed the average is 8.9x spot, with a 2x seed after a stale gap it is 1.78x spot. The NatSpec at line 53 claims 'a bad seed cannot persist'; it does whenever trading is sparse, which is exactly the regime in which the reseed path fires. Consequences while the average is inflated (TAU_LONG = 84h, so for about 1-2 weeks of sparse trading): sellExtra() returns MAX_EXTRA (2.7%) for every large sell at the true market price, and _inDrawdown() is true, so releaseFloor() moves floorReserve to BURN_HOOK at RELEASE_MAX per hour during a drawdown that never happened. Who can cause it: the first >= 0.01 ETH trade after deployment or after any 2-day quiet period is the seed; a receipt's observed price is its own execution price, so a trader who pumps first (or trades after a pump) chooses the seed. Cost is the pool fee on the pump round trip (about 4.4% of pump volume, e.g. roughly 1.8 ETH to seed at 2x on a 100 ETH virtual reserve); it can also happen organically from one large buy's impact price. Verified: both specialists' scenarios (audit_flow bfcf3e4b and audit_economics fbd178a1) reproduce; they share this root cause and are merged here. Fix preserving the design: require a minimum number of tracked observations (and/or that the last update did not hit the step cap) before averagePrice() returns ok, and on a stale reseed keep the previous emaLong as the long seed instead of the new receipt's price. **Reproduction** Fresh case (attached proof): mocks etched at GOVERNANCE, DRAW and POOL_MANAGER; vm.warp(1_800_000_000). Real price P = spotPrice(32<<96) = 976562500000000. Receipt 1 at t0: buy, amount0 = -0.01 ether, amount1 = 0.01e18*1e18/(10P) (seeds emaShort = emaLong = 10P). Receipt 2 at t0 + 1 day: buy, amount0 = -1 ether, amount1 = 1e18*1e18/P. Expected: averagePrice() not valid, or sellExtra(32<<96) == 0 because spot equals the market price. Actual: averagePrice() = (true, 8.888P), sellExtra(32<<96) == 27000, _inDrawdown() true. Stale-gap case (test_staleReseedPersists in test/scratch/JudgeRepro.t.sol): 26 hourly 1 ETH buys at 1000 CLAUS/ETH make the oracle valid at 1e15 with last observation T; at T + 2 days + 1 one buy amount0 = -0.01 ether, amount1 = 5e18 (price 2e15) reseeds both averages to 2e15 with no bound; at T + 3 days + 1 hour one honest buy (-1 ether, 1000e18) makes averagePrice() = (true, 1775139413563591); sellExtra(2505414483750479311864138015696) == 27000 at spot 1e15; releaseFloor() one hour later records drawdownSince != 0. Run: FOUNDRY_REMAPPINGS='forge-std/=/src/' forge test --match-path test/scratch/Proof_bfcf3e4b4d9b.t.sol (fails on current code). **Proof**: a Foundry test that fails on this code and passes once it is fixed. ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.8.26; import "forge-std/Test.sol"; import {DynamicSellFloorProgram} from "src/DynamicSellFloorProgram.sol"; import {ProgramTypes} from "src/IClausTradeProgram.sol"; contract MockGov { address public adapter; function set(address a) external { adapter = a; } function adapterFor(address) external view returns (address) { return adapter; } function approvedAdapter(address) external pure returns (bool) { return true; } } contract MockDraw { function startedAt() external pure returns (uint256) { return 0; } function endsAt() external pure returns (uint256) { return 0; } } contract MockPM { function balanceOf(address, uint256) external pure returns (uint256) { return 0; } function transfer(address, uint256, uint256) external pure returns (bool) { return true; } } contract OracleSeedTest is Test { DynamicSellFloorProgram p; address constant GOV = 0x180eAE784dEe739FBab432B06f78bF9a98Aae334; address constant DRAW = 0xF54c2f80c7A745C7b73F6c2035B7cAB87672f0A0; address constant PM = 0x000000000004444c5dc75cB358380D2e3dE08A90; address adapter = address(0xA11CE); uint160 constant SQRT_REAL = uint160(32 << 96); // 1024 CLAUS per ETH function setUp() public { vm.warp(1_800_000_000); // after every hard-coded draw / Buy&Hodl window vm.etch(GOV, address(new MockGov()).code); vm.etch(DRAW, address(new MockDraw()).code); vm.etch(PM, address(new MockPM()).code); MockGov(GOV).set(adapter); p = new DynamicSellFloorProgram(); } function _trade(uint256 id, uint256 ts, uint256 ethWei, uint256 claus) internal { ProgramTypes.Trade memory t = ProgramTypes.Trade({ id: id, module: adapter, sender: address(1), buy: true, amount0: -int128(int256(ethWei)), amount1: int128(int256(claus)), feeEth: 0, moduleFeeEth: 0, blockNumber: block.number, timestamp: ts, dataHash: keccak256("") }); vm.prank(adapter); p.onTrade(t, ""); } /// A seed at 10x the real price (one 0.01 ETH receipt), followed by ONE honest receipt /// at the real price exactly MIN_COVERAGE later, yields a "valid" average at ~8.9x the /// real price.

Currently it pays the full 2.7%. assertTrue(!ok || p.sellExtra(SQRT_REAL) == 0, "spot == real price but full sell extra charged"); } } ``` ### 2. Medium: Large-sell extra is avoided by splitting a sell into swaps of at most 0.5% of the virtual reserve, because isLargeSell is stateless and per swap `src/DynamicSellFloorProgram.sol:89` ``` if (!isLargeSell(amountSpecified, sqrtPriceX96, liquidity)) return a; // Day 7 ``` The only condition that routes a sell into sellExtra() is isLargeSell() (line 89), a pure function of the single swap's amountSpecified against 0.5% of the in-range virtual reserve (lines 97-107). quote() reads no per-sender, per-block or cumulative state, so N consecutive sub-threshold swaps in one transaction (Universal Router or any contract) deliver the same output as one large swap at the same price path, and each is quoted the base A5 only. The base 2.2% is paid either way; the only cost of splitting is gas. The sells the program exists to tax (large sells into a drawdown, up to 2.7% of gross) are therefore exactly the ones that can opt out, and floorReserve grows only from sellers who do not bother. Example on a 100 ETH virtual reserve at full deficit: one 10 ETH sell owes 0.27 ETH extra; 20 swaps of 0.5 ETH owe 0 and cost about 20 x 150k gas. This is inherent to the Day 7 per-swap size gate rather than a coding slip, so the fix is a design choice for the requester: (a) drop the size gate and let the deficit alone set the extra, (b) have the adapter pass cumulative per-block or per-sender sell volume in the quote data and gate on that, or (c) measure 'large' by the price move the swap would cause (post-swap price) rather than by amountSpecified. **Reproduction** State: oracle valid at emaLong = 1e15 (26 hourly buys of 1 ETH for 1000e18 CLAUS), liquidity L = 1e24, sqrtPriceX96 = 2717503554927417939056391812168 (spot 8.5e14, 15% below the average). reserve1 = (L * (sqrtP >> 32)) >> 64 = 34299717028501767865670754; piece = reserve1 * 50 / 10000. Input A: quote(any, false, -(20 * piece), sqrtP, L, '') -> a[5] == 29000 (base 2000 + MAX_EXTRA 27000). Input B: 20 calls quote(any, false, -piece, sqrtP, L, '') -> every a[5] == 2000. Expected: a sell of 10% of the reserve into a 15% drawdown pays the extra. Actual: 0 extra when split. test_splitSellBypassesExtra in test/scratch/JudgeRepro.t.sol. ### 3. Low: sellExtra uses only the pre-swap spot price, so a buy that lifts spot to the average removes the extra from a sell of any size `src/DynamicSellFloorProgram.sol:90` ``` a[5] = A5 + sellExtra(sqrtPriceX96); ``` sellExtra() compares the sqrtPriceX96 the caller passes to quote() (the pool price before the swap) with the slow average and returns 0 whenever spot >= avg (line 114). The oracle is rate bounded but the spot side is not. A seller who first buys enough to lift the pool to the average and then sells is quoted the base allocation for the sell regardless of its size, while the sell itself drives the price back below the average. Cost of the bypass is the base fee on both legs of the pump (about 0.044 x pump, where lifting the price by deficit d on virtual reserve R costs about R*d/2 ETH); the avoided extra is up to 2.7% of the sell, so the pump pays for sells above roughly 12% of the virtual reserve (R = 100 ETH, d = 15%: pump 7.24 ETH, fees 0.32 ETH, extra avoided on a 20 ETH sell 0.54 ETH). Splitting (previous finding) is cheaper and dominates today, so this matters once the size gate is fixed; it is kept separate because it needs a different fix: evaluate the deficit against the post-swap price (or min(pre, post)) or a short time-weighted price rather than the instantaneous pre-swap spot. **Reproduction** State: oracle valid at 1e15, L = 1e24. Input A: quote(any, false, -1e25, sqrtP = 2640938750475477889760800828730 (spot 9e14), L, '') -> a[5] == 20000. Input B, same oracle state after a buy moved the pool to sqrtP = 2505414483750479311864138015696 (spot = avg): quote(any, false, -1e25, sqrtP, L, '') -> a[5] == 2000, i.e. a sell of about 30% of the reserve pays no extra. Expected: a sell that large into a 10% drawdown pays 1.8% extra. test_prePumpZeroesExtra in test/scratch/JudgeRepro.t.sol. ### 4. Low: A late-delivered buy with an id below lastAttestedBuy never invalidates its reign, so crownKeeper succeeds on a reign the contract already holds a contradicting receipt for `src/DynamicSellFloorProgram.sol:415` ``` if (last != 0 && t.id > last && t.timestamp < uint256(buyTime[last]) + KEEPER_REIGN) { ``` _keeperOnBuy auto-contradicts only when the new receipt's id is greater than lastAttestedBuy (line 415). A buy receipt delivered late, whose id lies between an attested reign and its next attested buy and whose timestamp is inside that reign's 24h, is recorded in buyTime but contradicts nothing. keeperCrownable (lines 493-500) checks only keeperOf, reignCrowned, reignInvalid, scanThrough and the next attested buy's time, none of which this receipt touches, so anyone can crownKeeper the reign and push it into the hall of fame after the contract already knows the keys moved. The property stated at lines 386-387 ('A delivered buy that contradicts the attested coverage invalidates the affected reign') therefore holds only for the latest reign; earlier reigns depend on a separate permissionless invalidateBySkippedBuy call that races with crownKeeper. No ETH or claim value depends on the crown, so impact is a wrong hall-of-fame entry that must afterwards be flagged via reignRevoked. Minimal fix preserving the design: in _keeperOnBuy, when t.id < lastAttestedBuy, walk back a bounded number of attested ids (add a prevAttestedBuy link set in _attestKeeper) to the attested id just below t.id and call _contradict if t.timestamp < buyTime[thatId] + KEEPER_REIGN. **Reproduction** State: buy id 10 delivered at T0 and attested (wallet 0xBEEF); buy id 20 delivered and attested at T0+25h; attester calls attestScan(T0+24h). Input: adapter delivers buy receipt id 15 with timestamp T0+5h (accepted: timestamp <= block.timestamp, id unused). Expected: reign 10 invalid (keeperCrownable(10) == false, crownKeeper(10) reverts KeeperNotReady). Actual: keeperCrownable(10) == true and crownKeeper(10) succeeds, pushing (0xBEEF, T0, T0+24h, 10) into the hall of fame.

Low: Receipt replay guard and keeper state are keyed on trade.id alone, so a replacement adapter whose ids overlap is rejected or ignored `src/ClausDrawFundingProgram.sol:44` ``` if (trade.module != msg.sender || drawReceiptConsumed[trade.id] || trade.dataHash != keccak256(data) || trade.timestamp > block.timestamp) ``` GOVERNANCE can change adapterFor(program) after this review. drawReceiptConsumed (line 44), buyTime, the strictly increasing attestation chain (lastAttestedBuy) and nextAttestedBuy are keyed only on trade.id, not on (module, id). If a new adapter numbers its receipts in a range that overlaps ids the old adapter already delivered: (a) onTrade reverts DrawFundingInvalidReceipt for every overlapping id, so those receipts' fee accounting (recipientAccrued/floorReserve), oracle updates and volume are never recorded; (b) _keeperOnBuy returns early for ids that already have buyTime, and _attestKeeper reverts for any id <= lastAttestedBuy, so the keeper feature stalls. Whether ids can overlap depends on how the external adapter numbers receipts, which this repository does not show; that is an assumption, so severity is low. Fix: key consumption and keeper state on keccak256(module, id), or record the adapter in effect and namespace on change. **Reproduction** Mock GOVERNANCE.adapterFor = A, approvedAdapter(A) true. A delivers a receipt with id = 1 (succeeds). Governance sets adapterFor = B. B delivers its own first receipt with id = 1 and module = B. Expected: accepted, a different receipt from a different adapter. Actual: reverts DrawFundingInvalidReceipt(). test_adapterSwapIdOverlap in test/scratch/JudgeRepro.t.sol. ### 6. Info: quote() and onTrade() hard-depend on DRAW.startedAt()/endsAt(); the try/catch in floorShare can never engage `src/ClausDrawFundingProgram.sol:36` ``` if ((block.timestamp < IClausDrawWindow(DRAW).endsAt() || block.timestamp < BUY_HODL_END) && allocation[5] < 2000) ``` The inherited quote (line 36) and onTrade (line 49) call IClausDrawWindow(DRAW).endsAt()/startedAt() unguarded, so any revert or missing code at DRAW makes every quote and every receipt delivery revert. The override's floorShare (DynamicSellFloorProgram.sol lines 173-179) checks DRAW.code.length and wraps both views in nested try/catch, but it runs only after the parent's unguarded calls have already succeeded, so that defence is dead code and suggests a graceful degradation that does not exist. On mainnet DRAW (0xF54c...f0A0) has 8527 bytes of non-proxy code and returns startedAt 1793200595 / endsAt 1793805395 (read on 2026-11-03), and post-Cancun code cannot be removed, so the failing state was not observed; recorded as a dependency and dead-defence note. If graceful degradation is wanted, move the try/catch into the parent's quote/onTrade (a failed window read means 'outside the window'); otherwise drop the dead guard. **Reproduction** State: no code at DRAW (vm.etch(DRAW, '')), as in any non-fork environment. Input: quote(any, true, -1e18, 2**96, 1e18, '') or onTrade(validReceipt, '') from the approved adapter. Expected if the floorShare defence were effective: base allocation returned / receipt processed with the draw deduction skipped. Actual: both revert before floorShare runs, while floorShare(sellReceipt) called directly succeeds. test_quoteRevertsWithoutDrawCode in test/scratch/JudgeRepro.t.sol. ### 7. Info: Trust assumptions: operator-controlled GOVERNANCE selects the adapter that fabricates every receipt; RECIPIENT and ATTESTER are single EOAs; DRAW window read live `src/ClausDrawFundingProgram.sol:42` ``` if (msg.sender != authority.adapterFor(address(this)) || !authority.approvedAdapter(msg.sender)) ``` Inventory of the privileged roles and mutable dependencies that can change behaviour after this review (merged from audit_economics bb296070 and audit_permissions c321b3c5). (1) onTrade accepts receipts only from adapterFor(this) that is also approvedAdapter, both read at call time from GOVERNANCE 0x180e...e334 (6585 bytes of code on mainnet; operator() = 0xAB71...2073, an EOA with no code). The operator can at any time point adapterFor elsewhere (every further onTrade here reverts DrawFundingUnauthorized) or approve an adapter that fabricates receipts: the program verifies only module == msg.sender, unused id, dataHash and timestamp <= now, and trusts id, amounts (oracle, hyperdrive volume, keeper), feeEth and moduleFeeEth (recipientAccrued/floorReserve) with no on-chain cross-check. Verified mitigating property: even a hostile adapter cannot direct claims to itself. collectFees pays only RECIPIENT and only up to balance - floorReserve (line 212 of the override), _maybeRelease pays only BURN_HOOK and only up to balance - pending, and the base pays only DRAW_FUNDING and BUY_HODL; the worst a hostile adapter can do is re-split held claims between those fixed destinations and skew the oracle. (2) RECIPIENT 0x5a42...d995 and ATTESTER 0x8aCA...4cFa have no code on mainnet: the native transfer in unlockCallback cannot re-enter, and keeper wallets/scan coverage are a single-key trust. (3) DRAW_FUNDING and BUY_HODL have code (8350 and 6761 bytes) and no EIP-1967 slots. (4) Assumptions this repository cannot verify: that the adapter transfers trade.moduleFeeEth in id-0 claims before or during onTrade (the invariant balance >= floorReserve + pending depends on it), and that a sell receipt's amount0 is gross ETH before fee (floorShare line 170 and _recordVolume line 338 treat it so; if it is net of fee, floorShare diverts part of the base module fee to floorReserve). **Reproduction** State: GOVERNANCE.adapterFor(program) returns X and approvedAdapter(X) is true. Input: X calls onTrade with Trade{id: fresh, module: X, buy: false, amount0: 1e18, amount1: 1, feeEth: 0, moduleFeeEth: 1e18, timestamp: block.timestamp, dataHash: keccak256('')} and data ''. Actual: accepted; recipientAccrued and/or floorReserve rise by 1e18 without any claims arriving, and the next collectFees/releaseFloor pay out of whatever claims the program already holds, bounded by the two balance checks. Conversely after the operator calls setModule(other) on GOVERNANCE, the previously valid adapter's onTrade reverts DrawFundingUnauthorized at lines 42-43. Expected: by design; recorded as the trust boundary, not a bypass. ### 8. Info: Floor reserve destination BURN_HOOK is an EIP-1967 transparent proxy whose upgrader could not be identified; released claims follow whatever implementation is installed later `src/DynamicSellFloorProgram.sol:60` ``` address public constant BURN_HOOK = 0x37Bfb8AC7C960E558657871D41Ca70E07e7DbfFf; ``` _maybeRelease (line 310) transfers PoolManager ETH claims (id 0) to BURN_HOOK permissionlessly, up to 0.05 ETH per hour, and in stale mode without any price condition. Read on mainnet on 2026-11-03: 0x37Bf...bfFf holds 3070 bytes of proxy code; its EIP-1967 implementation slot is 0xa62f9b597225779b430024398b70374e8468ce14 (24261 bytes) and its admin slot is 0x1f22e4b065b2f15fed5be556dc0fa636048d29bc (1018 bytes, owner() returns the zero address, so it is either a renounced ProxyAdmin or a different pattern; the upgrader could not be determined). The program cannot pause or redirect releases. Whether the hook spends ERC-6909 claims pushed to it by a third-party transfer, rather than only claims it minted itself, could not be verified without its source; if it does not, released reserve is stranded in the hook's claim balance. Record the upgrade authority of 0x37Bf... and the hook's handling of externally transferred claims as explicit trust assumptions before launch. **Reproduction** State: floorReserve > 0 and either the drawdown condition held for 1h or no non-dust receipt for 2 days. Input: anyone calls releaseFloor(). Actual: PoolManager.transfer(BURN_HOOK, 0, amount) succeeds unconditionally (ERC-6909 has no receiver hook) and floorReserve is reduced; what happens to the claims is decided by the proxy's current implementation. Observed: cast storage 0x37Bfb8AC7C960E558657871D41Ca70E07e7DbfFf 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc -> 0x...a62f9b597225779b430024398b70374e8468ce14; admin slot 0xb53127...6103 -> 0x...1f22e4b065b2f15fed5be556dc0fa636048d29bc. ### 9. Info: No recovery path: id-0 claims above floorReserve + pending, and claims of any other currency id, are permanently stuck `src/DynamicSellFloorProgram.sol:212` ``` if (IFloorClaims(POOL_MANAGER).balanceOf(address(this), 0) < amount + floorReserve) revert CollectInvalid(); ``` The only two outflows are collectFees() (bounded by recipientAccrued - recipientCollected, line 211) and _maybeRelease() (bounded by floorReserve). Any id-0 claim balance not represented in those counters (rounding dust from the base contract's halving, claims transferred directly to the program, adapter over-delivery) can never be moved, and claims of any other currency id are not handled at all. There is intentionally no owner, so this is a design consequence rather than a defect; it is reported because the task asks for custody and recovery to be checked. If the requester wants it closed: let anyone sweep max(0, balance - floorReserve - pending) of id 0 to BURN_HOOK or RECIPIENT via the existing unlock/burn/take path, which adds no new trust. **Reproduction** State: floorReserve = 0, recipientAccrued == recipientCollected. Input: any account transfers 1 wei of PoolManager claim id 0 to the program. Actual: collectFees(1) reverts CollectInvalid (amount > pending = 0); releasable() returns (0, false); releaseFloor() returns 0; no other function moves claims. Expected under the task's recovery check: a bounded, permissionless sweep to one of the fixed recipients. test_strayClaimStuck in test/scratch/JudgeRepro.t.sol. ### 10. Info: Short-EMA rate limiter freezes permanently once emaShort is tiny (cap = s/2 rounds to 0 at s == 1) `src/DynamicSellFloorProgram.sol:246` ``` uint256 cap = s * MAX_STEP_BPS / 10000; ``` _observe bounds each short-average step by maxDelta = s*2500*dt/36_000_000 capped at cap = s*5000/10000 (lines 245-247), both relative to the previous short average and both rounding down. With s == 1 the cap is 0, so target is clamped to s on every later observation and the long average, which copies target during warm-up and is an EMA of target afterwards, is pinned too. More generally for s < 14400/dt the per-update step rounds to 0. The state is only entered through the unbounded (re)seed path (line 238) with a receipt whose amount1 >= amount0 * 1e18, i.e. >= 1e34 CLAUS base units against 0.01 ETH, which is not achievable at any plausible CLAUS price; reported as a verified numerical boundary, not an exploitable defect. Once stuck, averagePrice stays (true, 1) after warm-up, so sellExtra returns 0 for every large sell and _inDrawdown is always false until a stale reseed. Minimal fix: floor maxDelta at 1 (if (maxDelta == 0) maxDelta = 1) or reject seeds below a sanity floor. **Reproduction** Fresh deployment, DRAW window closed. Receipt 1: buy, amount0 = -0.01 ether, amount1 = 1e34 -> oracle = (1, 1, t0, t0). Then one buy per hour for 30 hours, amount0 = -1 ether, amount1 = 1e25 (price 1e11). Expected: the short average converges toward 1e11 within the 25%/hour bound. Actual: oracle.emaShort == 1 and oracle.emaLong == 1 after 30 observations; averagePrice() == (true, 1); sellExtra(any) == 0. test_seedOneFreezes in test/scratch/JudgeRepro.t.sol. ### 11. Info: sellExtra treats a spot price that rounds to 0 wei as missing data, dropping the extra at the deepest possible deficit `src/DynamicSellFloorProgram.sol:114` ``` if (spot == 0 || spot >= avg) return 0; ``` spotPrice returns ETH wei per 1e18 CLAUS as an integer and returns 0 for sqrtPriceX96 above about 7.92e37 (below Uniswap's MAX_SQRT_PRICE of about 1.46e48), where the true value is below 1 wei. sellExtra uses spot == 0 as the same sentinel as 'no price' (line 114) and returns 0, although with a valid average a zero spot is the maximal deficit and MAX_EXTRA is the intended result. Reaching this region requires the pool price to exceed 1e18 CLAUS base units per ETH, so it is a verified boundary of the formula rather than a reachable loss on the current pool. Minimal fix: return 0 only when sqrtPriceX96 == 0 and let spot == 0 fall through to the deficit computation. **Reproduction** Oracle warmed up with a valid average (26 hourly 1 ETH buys at 1e15). sellExtra(uint160(8e46)) -> expected MAX_EXTRA (spot far more than 15% below avg); actual spotPrice(8e46) == 0 and sellExtra == 0, while sellExtra(uint160(7e37)) == 27000. test_spotZeroDropsExtra in test/scratch/JudgeRepro.t.sol. --- Judge's submission `7c099837c6ed0934d246d4822ccab4ad7395ade4c09f7c41e158b613a27b086d`, accepted on the IdentityMD network.
