if (a.agreed < a.quorum || a.agreed > a.panelSize) return 4;
The oracle-consumer reference's _verifyAttestation 'checks the window and the signature'. check() verifies answer type, panel, quorum, agreed and the signer; TaskVault clamps the signed issuedAt into [askedAt, now] to decide 'in time', but an attestation whose expiresAt has passed is accepted.
Today the only sender is the Intake (msg.sender == via.intake), which delivers at once, so this is hardening: if the Intake ever re-delivers a stale signed answer (validForSeconds is 30 days in bodyFields) the vault records it.
Smallest fix: return a new code when a.expiresAt != 0 && a.expiresAt < block.timestamp (fits the 200k callback budget). Reported by audit_economics; confirmed by code reading (no expiresAt read anywhere in check()).
Build an attestation with expiresAt = block.timestamp - 1 (Base._attestation sets expiresAt = now + 1 days; set a.expiresAt = uint64(block.timestamp - 1)), sign it with the attester key and deliver it through MockIntake.complete for a pending request.
Expected: ignored (AttestationIgnored) and the case stays pending until the timeout.
Actual: check returns 0 and _recordAnswer stores it as the final answer.

Audit mathAgent #1094found 1 medium, 1 low, 1 info
The findings file is written and verified (snippets match their lines; no existing file was touched). With the time left, here is the report.
1. Verdict
Not blocked by the math at the money core. The liabilities invariant, every split and every claim bucket close exactly, and the baseline reproduces (318 passed, 5 fork suites skipped). What I would fix before launch: the YOLO price oracle, whose "EOA-only" sampling does not survive a same-block sandwich, so one pumped sample becomes the YOLO price for two hours and steers trophy prices, sweetener payouts and YOLO-task bonds. Severity medium. One low (vesting clocks) and one info. No critical or high.
2. Code findings
[Medium] YOLO price sample can be sandwiched inside one block.
contracts/src/oracles/YoloPoolSamples.sol:60. The guard stops a contract from swapping, sampling and swapping back in one transaction, but three transactions of one EOA in one block (nonce order or a bundle) do the same with no inventory risk. Since the price is the highest sample of 2 h, one pumped sample is the price for two hours and seven later honest samples do not displace it. With launch values (opening 1.5e-5 IMD per YOLO, cap $0.01) the move is up to 87x. Effects: trophy price drops from about 13,000 YOLO to about 150; the sweetener cap drops from about 2.6M YOLO to 30,000 (the sweetener claws back up to 98.8% of an unconfirmed bonus by callingpayoutthemselves); every YOLO task's doer bond grows up to 87x and rewards above about $3.45 real become "large" (0.5 IMD check prepaid by the doer). Cost to reach the cap on the 150M single-sided position: about 2 × 1.25% of roughly 18,750 IMD notional, near $3,600; a 10x pump near $930. PoCcontracts/test/scratch/SampleSandwich.t.sol(two tests, both fail now). Fix: a sample counts only when confirmed by the next sample at least 15 minutes later within a tick band, so a price must be held across blocks.[Low] Vesting clock can be started by anyone with 1 wei before the split.
contracts/src/token/ProjectVesting.sol:63. The split is not in the launch transaction, andreleasestarts the clock on any nonzero balance. An NFT holder who bought in minute 0-30 sends 1 wei to a vesting and callsrelease; at the split a day later 213,089.8 YOLO of the dev share is already free (0 expected). That is the gap audit A-03 meant to close, bounded by the launch-to-split delay the project controls. PoCcontracts/test/scratch/VestingClockPreStart.t.solfails now. Fix: only the splitter may start the clock.[Info] Sweetener cap "floor of 30,000 YOLO" is $3.45 at the opening price.
contracts/src/YoloSweetener.sol:170. Documented as harmless; it is the doer's loss in the finding above.3. Business logic and concept risks
- Pump-then-payout on sweetened tasks. Gains: the sweetener; loses: the doer, up to the whole bonus above 30,000 YOLO. Cost near $1k to $3.6k in swap fees per 2 h window. Recommend the median sample for payouts and letting a doer order the swarm check on a sweetened task.
- Tie rule. With no NFT votes, disputers lose their whole bond (50% to the doer, 50% treasury). Honest disputing costs 1 IMD plus 0.0003 ETH plus the risk of voter apathy, so a disputer must also budget 1.5 IMD for a swarm call. Recommend returning disputer bonds when no vote was cast at all.
- Relayer gas eats the winners' share. Shortfall is paid from the loser's bond before winners; at mainnet gas, ten votes cost more than a 1 IMD bond, so winning small disputes pays nothing beyond bond return. Documented, but it removes the voter incentive on small tasks.
- Stabilizer / MM fund. 150M unlocked at day 0 to one wallet, with the treasury wallet also receiving the buy tax. Recommend a public address, a stated maximum daily sell, and on-chain reporting; the fund stays.

Task with a 2,600,000 YOLO bonus (~$300 at the opening price), small reward, accepted without a swarm answer.
One sandwiched sample at the $0.01 cap (see the YoloPoolSamples finding) then payout: _cap = 300e18 * 1e18 / 0.01e18 = 30,000 YOLO; doer receives 27,000 YOLO after the 10% fee, 2,570,000 YOLO return to the sweetener.
Expected (honest price): the doer receives 2,340,000 YOLO.
Audit permissionsAgent #911found 2 medium, 4 low, 1 info
Only new files exist under the scratch directory;
.imd-findings.jsonis ignored by git but present in the repo root. Here is the report.1. Verdict
Not blocked for launch on code grounds: no path to theft, double payment or stuck money was found in the permission model. Two medium items should be settled before launch: the vesting clock can be started by anyone before the split (a guaranteed-by-docs behaviour that fails), and the author can withdraw the reward the instant a public proof appears, which makes honest doing a losing strategy against a dishonest author. Both are cheap to fix. Everything else is low or informational.
2. Code findings (most severe first)
M-1. Vesting clocks can be started before the share arrives.
contracts/src/token/ProjectVesting.sol:63.releaseis permissionless and starts the clock on the first call that finds any balance. Between launch 1 andsplit(a separate transaction) anyone sends 1 wei of YOLO to a vesting and callsrelease; the head start vests at the split. A split delayed 30 days frees ~6.39M dev YOLO at once. Reachable at launch values. Fix: start the clock only from the splitter, or require the expected balance. PoCcontracts/test/scratch/VestingClockPreStart.t.solfails on this code (clock must start at the split: 1 != 2592001); full source is in the findings file.M-2. Author withdraws after seeing the public proof.
contracts/src/TaskVault.sol:305. Every proof type is public beforesubmitcan be called; the author front-runs withwithdrawContribution, the doer'ssubmitrevertsRewardTooSmall, and the author has the work for the 0.0005 ETH fee. Documented in MECHANICS but not as a risk; the sweetener got a 1 h notice (R-3), the vault did not. Fix: the same announce-then-withdraw rule for active shares.L-1. Unconfirmed sweetener bonus returns in full without a YOLO price.
YoloSweetener.sol:170.payoutis permissionless; when the keeper lapses ~25 minutes or Chainlink is stale, the cap is 0, the doer gets nothing and the sweetener takes everything back.L-2. Doer self-appeal.
DisputeDesk.sol:127. The doer may appeal an Accept decision against themselves, taking the single appeal slot and writing both the appeal and its reply.L-3. One wallet votes both sides.
VoteLib.sol:103. A holder splits NFTs across sides and is paid as a correct voter whichever side wins.L-4. Relayer reimbursement filled to the cap with wasted gas.
DisputeDesk.sol:431. Skipped ERC-1271 burner ballots are metered; the shortfall is taken from the loser's penalty before winners.I-1. Attester removal silences the swarm for live tasks.
ParamsRegistry.sol:183. A documented owner power, but its effect on open cases (checks pass, appeals void, ties accept) is not disclosed.3. Business logic and concept risks
- Reward is not locked (M-2). Author gains the work, doer loses it. Cost ~$2. Recommend a withdrawal notice.
- Optimistic default favours doers. NoDecision with no swarm call ends Accepted and the honest disputer loses their full bond (50% to the doer, 50% treasury). A disputer must pay 0.5 IMD plus bond to be judged. With NFT turnout below margin 10, junk submissions pass unless someone pays. Recommend a tie rule that returns disputer bonds when nobody judged.
- Price liveness is an unpaid EOA keeper. Without 5 samples per 2 h, every YOLO task is large (0.5 IMD check, 40 IMD bond base), bonuses return to givers (L-1), trophies cost 10,000 YOLO. Recommend the project commits to run and monitor the sampler, and that the sweetener holds rather than returns without a price.
- Stabilizer / MM fund, 150M unlocked day 0. Stays per the owner. Risk to holders: one EOA holds 15% liquid plus 74M treasury and 62.5M incentives at once, 54% circulating on day 0 against a $10M cap valuation. Recommend a published MM mandate, a separate signer from the params owner, and on-chain disclosure of that wallet.
- Demand for $YOLO.

Without a live YOLO price an unconfirmed sweetener bonus is returned in full; anyone picks the momentcontracts/src/YoloSweetener.sol:170
_cap returns 0 whenever hasPrice(yolo) is false (fewer than 5 samples in the last 2 h, i.e. the optional EOA keeper lapsed for ~25 minutes) or any oracle call reverts (stale Chainlink feed). payout is permissionless, so for every accepted submission the swarm did not confirm (every small task without a dispute) the sweetener, or anyone, can call payout at a moment without a price and the whole bonus returns to the sweeteners; the doer gets 0 and payout cannot be rerun (returnBase != 0).
The behaviour is in the NatSpec ('no price = 0') but it turns a promised bonus into one the giver can take back after the work is done, with no notice, by timing a call.
Smallest fix: when no price is available, keep the bonus (revert NothingToPay until a price exists) or fall back to the uncapped path only when the task's own oracle has a price; at least let only the doer call payout.
The doer can appeal against their own accepted decision to occupy the single appeal slotcontracts/src/desks/DisputeDesk.sol:127
State: submission 1 in Phase.Decided with nftDecision = Accept, appeal window open.
Doer D calls appeal(1, 'they are right, reject me', maxImdIn, payIn).
Expected: NotOpponent-style revert (a party cannot represent the other side).
Actual: appeal recorded with appellant = D, sidesDoer = false; a disputer's appeal(1, ...) now reverts WrongPhase (phase is Appealed); D calls appealReply(1, 'ignore the above') successfully because sender == s.doer.
One wallet may vote both sides and always collect the correct-voter rewardcontracts/src/libraries/VoteLib.sol:103
walletSides is a bitmask, so a holder of N NFTs can sign one accept ballot with half of them and one reject ballot with the other half. Each NFT counts once, but the wallet is counted as a distinct winner wallet on both sides and its payTo collects a share of voterImd (50% of the loser bond) and voterFee (6% of R) whichever side wins, at zero risk. Honest voters who commit are diluted; a large holder can also inflate walletsAccept/walletsReject.
Not a theft, but it makes the 'correct NFT voters' reward farmable without judging.
Smallest fix: skip a ballot whose voter already voted the other side on this submission (seen & ~sideBit != 0 -> BallotSkipped).
State: submission in Phase.Voting; wallet W owns tokens 1..20.
W signs ballot A (side 1, tokens 1-10, payTo W) and ballot B (side 2, tokens 11-20, payTo W).
Relayer submits both.
Expected: a wallet is on one side.
Actual: both counted (acceptVotesOf[W] = 10, rejectVotesOf[W] = 10, walletsAccept and walletsReject each +1).
After settlement on either outcome claimVoterReward(subId, W) pays W 10/left of the voter buckets.
Relayer reimbursement can be filled to the cap with deliberately wasted gascontracts/src/desks/DisputeDesk.sol:431
State: Phase.Voting, dispute pot 0.0003 ETH, relayer R owns 1 NFT.
R submits [ballot with a valid signature for token 1, ballot from a contract whose isValidSignature loops until out of gas].
Expected: reimbursement for ~40k gas of real work.
Actual: gasUsed ~540k, capped at 90k; cost = 90k x basefee x 1.1 credited from the pot, the rest booked as relayerShortfall and paid from the loser's bond at settlement.
Params owner can turn every swarm answer for live tasks into silence by removing the attester (48 h)contracts/src/ParamsRegistry.sol:183
Trust assumption to disclose rather than a bypass: the attester set is global and applies to the Intake callbacks of tasks already running. The single-EOA owner can proposeAttester(signer, false) and after 48 h anyone executes it; from then on AttestationChecker.check returns 5 for every answer and CaseDesk treats each question as silent: mandatory checks pass, appeals are voided (NFT decision stands), NoDecision ends in the tie rule (accepted), swarm fees of callers are lost.
The owner thus biases all open cases toward doers without touching money. MECHANICS.md lists the attester set as owner-changeable but not this effect.
Recommend: disclose it, and either pin the attester set per parameter version with the rest, or require a live attester at all times (refuse the removal of the last attester).
State: registry with one attester A, task in Phase.Asked waiting for an appeal answer.
Owner calls proposeAttester(A, false); 48 h later anyone calls executeAttester(A, false).
Intake delivers the signed 'no'.
Expected: Rejected.
Actual: AttestationIgnored(rid, 15); at askedAt + 6 h step() marks the request Silent, drops the caller (fee lost), and the NFT 'accept' decision stands and finalizes Accepted.

Verdict
Not blocked by any code defect I could reproduce: no theft, double payment or stuck-money path survived verification, and the baseline matches the docs (318 passed, 5 fork suites skipped). Four reproducible code findings, the worst two low. Three business-logic risks need an owner decision before launch: silence and the tie rule favour the doer, the single-key params owner can switch the swarm off for every open case after 48 h, and the Stabilizer wallet plus treasury hold 29% of supply on day 0 under one EOA with no controls. Launch is reasonable once the vesting clock guard is added and the disclosures below are published.
Code findings (full detail, call sequences and the PoC source are in
.imd-findings.json)- Low. Vesting clocks can be started by anyone with dust before the split.
contracts/src/token/ProjectVesting.sol:63starts a clock on the first permissionlessreleasewith any nonzero balance. YOLO trades from the launch-1 block,splitis a later call. Any holder sends 1 wei to a vesting and calls release. Expected: the dev clock starts at the split with nothing releasable. Actual: it starts at the dust transfer, and at a split 12 h later about 106,544 YOLO of the dev share is already free. Bounded by the launch-1-to-split gap; benefits the beneficiaries, breaks the published schedule. Reachable with launch values. Fix: require the compiled share to have arrived before starting the clock, or let only a fixed starter start it. PoCcontracts/test/scratch/VestingClockFrontRun.t.solfails on this code with1 != 43201. - Low. A late-delivered swarm answer counts only if nobody poked first.

Question asked at T, answer signed at T+1h, delivered at T+6h+60s: if the losing party calledpokeat T+6h the answer is silence (check skipped, window opens, caller's fee lost); otherwise it is final. Same inputs, opposite outcome, chosen by whoever pokes. Only bites when delivery is late. Fix: comparerecordedAtwith the deadline, or ignore answers to timed-out requests inonOracleResult. - Info. The doer may appeal their own Accept decision (
contracts/src/desks/DisputeDesk.sol:127), taking the single appeal slot and the opponent reply for about 0.5 IMD net. C-01 closed this for disputes, not appeals. Fix: refuseappealfrom the doer when the decision is Accept. - Info. Hedged voting.
contracts/src/libraries/VoteLib.sol:103lets one wallet vote both sides with disjoint tokens and collect the voter reward whatever the outcome, diluting real judges. Fix: skip a ballot whose wallet already voted the other side.
Business logic and concept risks
- Silence resolves for the doer. A silent or refused swarm question (Intake down, body refused as ambiguous, price raised above the prepayment) skips the mandatory check and, after an undecided NFT vote, the tie rule accepts. A doer with a bogus proof on a $300 USDC task gains 270 USDC for a 1.68 IMD bond if the swarm never answers; each disputer attempt to call it costs 0.5 IMD lost per silence plus gas. Who loses: the author. Recommendation: when a dispute exists and every swarm call went silent, default to the NFT majority if any, else to rejection with all bonds returned, or at least never to acceptance on a case the swarm refused.
- Honest disputing of small dares is unprofitable for third parties. A winning disputer earns 50% to 100% of a bond of 1 to 1.7 IMD ($7.65 to $13) and pays dispute, call-the-swarm and claim gas plus 0.5 IMD fee at risk. Only the author has a real incentive, and the author as contributor gets only their bond back. Expect few disputes from the crowd; disclose this and consider paying the caller's gas from the losing bond.
- The params owner can turn the swarm off for all open cases. A single EOA proposes removal of the only attester; after 48 h every callback is ignored, an

Launch-ready from a money-safety standpoint: I found no path to theft, double payment or stuck funds, and the liabilities invariant holds in every outcome I traced. One medium finding blocks launch as the economics stand: a losing, stake-free NFT voter can take the whole loser penalty as relayer gas, which removes the payout that is supposed to reward winners and honest voters. Two lows (vesting clock pre-start, doer capturing the appeal slot) and four info items should be fixed or disclosed before launch. The 15% Stabilizer / MM fund is kept as the owner's decision, with controls recommended in section 3.
2. Code findings, most severe first
M-1 · Medium · Relayer shortfall is paid from the loser's penalty before winners and correct voters, whatever side the relayer voted for
- Where:
contracts/src/desks/DisputeDesk.sol:507(_settleDecidedstep 1),:422-447(_reimburseRelayer),:255-270(claimRelayerShortfall). - Impact: cheap griefing. A voter on the losing side relays their own ballots one NFT per batch and is reimbursed up to (30k + 60k) gas × basefee × 1.1 per batch, first from the dispute ETH pot, then as IMD shortfall at the submission's IMD/ETH rate. The shortfall is paid from the penalty before the 50/50 split, so the winning doer gets only their own bond back and the correct votes get nothing. NFT voters stake nothing, so the attack costs the griefer about zero net (reimbursement is 1.1 × basefee against basefee + tip). It also removes the only reward that makes honest NFT voting worthwhile.
- Call sequence:
createTask→submit→dispute→submitVotes× 20 from the losing voter's own wallet (one tokenId each) → vote endpoke→ 24 h →poke→claimRelayerShortfall. - Concrete state: $100 USDC task, doer bond 1 IMD, one dispute bond 1 IMD, basefee 20 gwei. 120 NFTs accept, 20 NFTs reject (20 batches). Expected per MECHANICS:
voterImd0.5 IMD, doer +0.5 IMD. Actual: shortfall recorded 12.375 IMD,shortfallPay= 1 IMD,voterImd= 0, doer credit = 1 IMD only. - Launch values: reachable (relayBaseGas 30k, maxRelayGasPerVote 60k, markup 10%, minDisputeFee 0.0003 ETH). At IMD = $7.65 a $300 task has a 1.68 IMD doer bond and 1 IMD dispute bonds; the same 20 batches at 20 gwei (≈ $82 of gas) cover any realistic penalty.
- Smallest fix: record shortfall per side (the side of the votes the batch counted) and pay only the shortfall of batches whose votes were on the final side; or cap total shortfall taken from the penalty (e.g. at most
BPS - winnerBondBps) so winners and correct voters always keep a share. - PoC

The launch pins the version 1 Intake; the IdentityMD oracle-consumer reference says new consumers must use version 2contracts/script/LaunchPlan.sol:52
Compare contracts/script/LaunchPlan.sol:52 and docs/LAUNCH-TASK.md:184 ('0x1397434cd35e8a9c8ac312a61d3a285eb31dea56') with the oracle-consumer reference table: version 2 is 0xa43e6f75ee006411f79ac1c84120606c2330de82.
Expected: a new mainnet consumer points at version 2.
Actual: version 1.
AttestationChecker does not check expiresAt (nor a.chainId), unlike the protocol's _verifyAttestationcontracts/src/helpers/AttestationChecker.sol:51
The oracle-consumer reference says the consumer's _verifyAttestation 'checks the window and the signature'. check() verifies answer type, panel, quorum, agreed and the signer, and TaskVault clamps the signed issuedAt into [askedAt, now] to decide 'in time', but an attestation whose expiresAt has passed is accepted as a final answer.
Today the only sender is the Intake, which delivers at once, so this is hardening only: if the Intake ever re-delivers or delivers a stale signed answer (validForSeconds is 30 days in bodyFields), the vault would still record it.
Smallest fix: return a new code when a.expiresAt != 0 && a.expiresAt < block.timestamp (fits the 200k callback budget).
Build an attestation with expiresAt = block.timestamp - 1 (the Base test helper uses _attestation(answer) with expiresAt = now + 1 days; set a.expiresAt = uint64(block.timestamp - 1)), sign it with the attester key and deliver it through MockIntake.complete for a pending request.
Expected: ignored (AttestationIgnored) and the case stays pending until the timeout.
Actual: attestationChecker.check returns 0 and _recordAnswer stores it as the final answer.
Docs drift: the registry owner can set the judge (Intake, NFT contract, attester, delegate registry) for all future tasks, which the docs summarise as 'cannot move, freeze or redirect deposits'contracts/src/ParamsRegistry.sol:16
True for live tasks, but a proposed version (48 h public, in bounds) may change intake, nft, delegateRegistry and priceOracle, and proposeAttester changes the accepted signers for every open case. Pointing a future version at an Intake or NFT contract the owner controls decides every future case (and thus every reward) created under that version; a signer change reaches open cases but only through a callback the real Intake delivers (B-02 argument).
This is the owner's largest lever and an intentional single-EOA role; it should be stated as such in docs/MECHANICS.md 'Trust assumptions' and README.md ('there is no admin over funds') rather than only 'parameters for future tasks', and the owner key should at least be a hardware key or multisig with the proposals monitored. Not a code defect.
Windows that follow swarm silence start at a computed past moment, so they can be fully elapsed when first observed; a doer gains by nobody pokingcontracts/src/desks/CaseDesk.sol:156
Large task (USDC 300e6): doer submits and prepays the check; the Intake never answers and nobody calls the vault.
30 h 1 s later anyone calls poke(taskId).
Expected (a disputer's reading of the docs): a 24 h dispute window is open now.
Actual: step() sets windowEnd = askedAt + 6 h + 24 h (already passed) and the next iteration finalizes Accepted; dispute(subId) reverts WrongPhase.

The review is complete. The findings file holds 11 merged, reproduced findings, all anchored to lines that match the tree, and no existing file was touched.
1. Verdict
Not ready for mainnet as it stands. Nothing found is a theft or a bricked launch, but three medium items undercut public promises: the YOLO price oracle can be set for two hours by one sandwiched sample, the vesting clocks can be started by anyone with dust before the split, and a losing-side voter can eat the whole loser penalty through relayer reimbursement so winners and correct voters get nothing. Fix those three plus the two one-line guards (doer self-appeal, two-sided voting) before launch.
2. Code findings (most severe first)
# Sev Where Finding Proof 1 medium YoloPoolSamples.sol:60 EOA-only sampling stops a single-transaction sandwich only. Swap, sample, swap back in three transactions of one block pumps the highest-of-2h price up to 87x for ~$3,600 in LP fees. Lowers trophy price 99%, cuts the sweetener cap to ~$3.45, inflates YOLO-task bonds 87x. SampleSandwich.t.sol, fails 2 medium ProjectVesting.sol:63 Anyone with 1 wei of YOLO starts a vesting clock before the split, so the A-03 promise "clocks start at the split" fails. 30-day gap frees ~6.39M dev YOLO at the split. Merged from four specialists. VestingClockPreStart.t.sol, fails 3 medium DisputeDesk.sol:507 Relayer shortfall is paid from the penalty before winners and voters, for any side. A losing voter relaying 20 one-NFT batches at 20 gwei records 12.375 IMD shortfall against a 1 IMD penalty; correct voters get 0. Reproduced in JudgeChecks.t.sol with the Base harness, not self-contained 4 low DisputeDesk.sol:127 Doer may appeal their own acceptance, hold the single appeal slot and write both appeal texts. Reproduced 5 low VoteLib.sol:103 One wallet votes both sides with disjoint tokens and is paid the voter reward whichever side wins. Reproduced 6 low YoloSweetener.sol:170 With no YOLO price the cap is 0, so anyone times payout to return an unconfirmed bonus in full; the doer gets nothing. Reproduced 7 low CaseDesk.sol:358 A late-delivered but in-time-signed answer is final only if nobody poked at the deadline first. Reproduced both ways 8 low TaskVault.sol:305 Author withdraws the active share the moment the public proof appears, with no notice, unlike the sweetener. Code reading 9 info AttestationChecker.sol:51 expiresAt and chainId not checked. Code reading 10 info ParamsRegistry.sol:16 Attester removal silences all live cases after 48 h; a future version can point intake/nft at owner contracts. Disclose as trust assumptions. Code reading 11 info LaunchPlan.sol:52 Pins Intake v1 where the reference says use v2 for new consumers. Compared to reference Dropped or merged: the sweetener-cap info from audit_math is folded into findings 1 and 6; the ERC-1271 gas-burn route into finding 3; the "windows after silence start in the past" item matches the docs and was dropped.
3. Business logic and concept risks
- Reward withdrawal race (finding 8). Author gains the work for a $2 fee, doer loses the work. Add a one-hour notice for active shares while a task is Open.
- Voter reward farmable without judging (findings 3 and 5). Relayers and hedgers gain the voter pool, honest NFT holders lose their only incentive, so the NFT court decays. Pay shortfall per winning side and refuse two-sided wallets.
- Owner levers (finding 10). A single EOA can silence the swarm for every open case or redefine the judge for future tasks. Disclose, require a live attester, move the key to a multisig.
- Stabilizer / MM fund. Stays by owner decision. Risk to holders is 150M unlocked YOLO in one wallet at launch; recommend on-chain disclosure of the wallet, a published trading policy and a public report of its movements.
