IVaultWithdraw(vault).withdraw(token);
vaultis caller-supplied, so the burner (which holds ETH, USDC, IMD and YOLO) issues an attacker-chosen external call with msg.sender = burner. No contract in the repository exposes a withdraw(address) that would move the burner's funds and the burner grants no allowances, so no loss was found with the in-scope code; it is an unnecessary arbitrary-call surface (a future token or contract that acts on withdraw(address) from the burner would be reachable).Hardening: pin the vault (constructor argument or ProtocolDirectory lookup), or drop pull.
Merged: audit_permissions #2737fd78 and audit_flow #8b2e73ac (reproduced by code reading: lines 120-123 take

function withdraw(address) external { emit Called(msg.sender); }.Any EOA calls burner.pull(address(A), address(0)).

Task 1 (1,000 USDC, no add-on).
Doer submits (s.addon = 0).
Dave disputes; during the vote Carol calls YoloSweetener.sweeten(1, 10_000e18).
NFT holders vote accept -> Accepted; sweetener.payout(1): voterPool = 500e18. vault.claimVoterRewards([subId], V): V receives the IMD/USDC voter shares, voterClaimed(1, V) stays false and V receives 0 YOLO; a direct sweetener.claimVoter(1, V) then pays it.

DevPrices with yoloPriceUsd = 0.01e18.
Owner calls setYoloPriceUsd(0.1e18), setYoloPriceUsd(1e18), setYoloPriceUsd(10e18) in one transaction: all three pass _check, the price is 1000x.
A doer with 1 YOLO locked 52 weeks (power 1e18) submitting to a 1,000 USDC task now gets bps = 4 (yoloValue = 100e18 instead of 100,000e18); at a 100,000 USDC base it reaches the full 4%.
Expected per a strict reading of 'at most 10x per step': a cooldown; actual: unlimited move in one transaction.

bool appellantIsStranger = hasCaller && a.appellant != f.doer && a.appellant != d.disputer;
_fundCall (line 292) treats the disputer as 'a side' only when !sidesDoer; a disputer appealing a Reject decision for the doer's side (sidesDoer = true) posts the full second bond and pays the whole fee from the wallet like a stranger. At settlement the stranger fee carve-out (lines 636-640) excludes any appellant equal to d.disputer, so this caller gets no 0.5 IMD fee back while an unrelated wallet in the same position does. Asymmetry only, bounded by bondFixedImd.
Fix: define 'stranger' in _settleDecided by the test _fundCall used, e.g. a.fromBond == 0 && a.bond.imd != 0. From audit_permissions #d68add12 (reproduced by code reading).
Dispute by D, NFT decides Reject, D appeals with sidesDoer = true (only the doer is restricted), posts 0.5 IMD + 1% and the fee, swarm answers Accept: D is credited a.funds + a.bond + appPart but not strangerFee; an unrelated appellant in the same flow is also credited min(bondFixedImd, penaltyImd).
9.infoDisputeDesk.vote: a payTo record accumulates votes without a side, so one payTo can hold accept and reject countscontracts/src/desks/DisputeDesk.sol:164
if (side == VoteLib.SIDE_ACCEPT) pr.accept += uint120(power);
sideis fixed per voter wallet (lines 145-146), but a payTo named by another voter only gets its accept/reject counter incremented (lines 162-166) and its own side stays 0. The payTo wallet may later vote itself for the other side and is paid whichever side wins. Each NFT still counts once on one side and voterVotesLeft equals the sum of recs on the final side, so no money is created; a hedging possibility the 'one side per wallet' wording does not cover.From audit_permissions #d2d8b09e (reproduced by code reading).
A votes 5 ids accept with payTo = B; B votes 3 ids reject with payTo = B. votesOf(subId, B) = (5, 3); B claims on whichever side is final. No double payment.
10.infoParams.nft and Params.delegateRegistry are not read by the vote path; VotePower's immutables decidecontracts/src/desks/DisputeDesk.sol:185
(,, uint32 instantDelta, uint32 minWallets) = ParamsRegistry(registry).voteParams(version);
VaultParams.sol:16-17 says a version's nft / delegateRegistry govern voting and address(0) disables delegated votes. DisputeDesk.vote discards those two return values of voteParams and checks holders only through the immutable VotePower(nft_, delegateRegistry_) fixed at launch (VotePower.sol:21-24, DisputeDesk.sol:155). A proposed version with delegateRegistry = address(0) changes nothing.
MECHANICS 'Trust assumptions' states the VotePower rule correctly; the struct comments and bounds are the drift. No money impact. From audit_flow #108192c3 (reproduced by code reading).
Owner proposes and after 48 h activates params identical to version 1 except delegateRegistry = address(0); a task under version 2; a delegate of an NFT owner votes with the owner's ids.
Expected per the struct comment: NotTokenHolder.
Actual: the vote counts.

Correct for USDC and for YOLO today (YoloToken taxes only transfers to/from the PoolManager; a wallet -> vault transfer is untaxed), so liabilities <= balance holds; it would break the balance invariant if YOLO ever taxed wallet transfers.

if (t.status != TaskStatus.Open) revert TaskNotOpen();
cancelTask runs _advance before the status check (lines 369-370); a task with no active submission and deadline <= now becomes Expired in that call and cancelTask reverts TaskNotOpen. This matches MECHANICS.md:37 ('cancelTask of an Open task') and the NatSpec, so no rule is broken, but the dev cancellation cannot give predictors 100% back once the deadline passed: YoloPredict resolves the WON'T DO side as winner.
Contributions, add-ons and bonds still come back through the Expired paths. Document it. From audit_economics #83adc12e (reproduced by code reading).
Task 1 deadline T. At T+1 (nobody poked) the dev wallet calls cancelTask(1): _advance closes it as Expired and the call reverts TaskNotOpen; WILL DO predictions get 0.

uint256 left = (end - block.timestamp + WEEK - 1) / WEEK; // whole weeks, rounded up
lock(add, 0) on a running lock computes

No payout can be collected inside that second (stakePower needs the lock running at the payout, >= 24 h after any submission), so the only use is to re-set the lock for >= 1 week, which lock(add, 1) would have cost anyway.Hardening only. From audit_math #cd7afe3e (reproduced by code reading).
lock(1_000e18, 1) at T; warp T + 7 days - 1; lock(1_000e18, 0): Locked reports power 2 * 1_000e18 / 52 while the second 1,000 YOLO is withdrawable one second later.

Audit economicsAgent #19found 3 low, 2 info
I found no critical or high issues in the economics, so the contracts look deployable from that side. But I couldn't confirm it with tests:
forge build(via-IR) was still compiling after 20 minutes and was stopped, so nothing was built and no test ran. I wrote no PoCs, since none of the findings is high enough to need one. Five findings (three low, two info) are in.imd-findings.json.0. Verdict: Deployable on economics, with no blockers found by reading the code. Before launch:
- Get a full
forge buildandforge testrun to complete. - Accept two trust assumptions (item 5): the registry owner's attester and intake powers, and the dev wallet's control of the buyback wallet.
- Consider fixing the low items: the DevPrices step bound has no cooldown, and the swarm callback doesn't check the question hash.
- User approvals — no issue. Every pull takes from the caller:
- The vault pulls only from the sender it appends (
fallback) or frommsg.sender. _fundCallusesa.appellant, which is set from_sender()in the same call.- The other contracts' pulls (Sweetener, Predict, LockHub, DareTrophy) all use
msg.sender. - The swap adapter pulls only from its caller, and the vault approves it for
amountInthen resets the approval to 0. - No Permit2, delegatecall, arbitrary call or upgrade path exists. The routing table forwards no desk-only function.
- The vault pulls only from the sender it appends (
- Balance invariant — no issue. I traced every booking:
- ETH:
collectBondPartand_collectcount ETH, andsettleValuechecks the sum againstmsg.value. ask()removes the fee from liabilities, and_charge/sideSpentremove it from the right bucket.- Settlement splits add up to the reward (
r) and to the penalty. - YoloPredict and the Sweetener balance in every branch.
- ETH:
- Stuck money — no issue. A failed push becomes a credit, and the 30k-gas send to the buyback wallet falls back to the burner. A blacklisted USDC holder can use
withdrawTo. One low gap:claimVoterRewardsskips the YOLO add-on share when the add-on was added after submission (DisputeDesk.sol:441). The voter can still claim it directly from the Sweetener. - Reentrancy and routing — no issue. One transient lock covers every routed call, and views use STATICCALL.
routedandonlyguard the desks.onOracleResulthas no lock but accepts only the stored Intake and makes no external writes. - Access rights — info (trust assumption).
- The attester set is global. After the 48h timelock, an owner-added attester combined with an owner-chosen intake in a new version can decide the swarm answer on that version's tasks, which moves the pot.
setBuybackWalletredirects burn shares instantly.- Low: the "10x per step" price bound has no cooldown, so chained calls move a price by any factor. Only the stake bonus is affected (
DevPrices.sol:89). wirecan't be called twice or by anyone else.
- Cancel — no issue in code. Every party is refunded once and the dev wallet gets nothing. Info: once the deadline passes, a cancel first expires the task and then reverts, so predictions settle as WON'T DO instead of a full refund.
- NFT vote — no issue. A bitmap stops any id voting twice (a repeat in the list, a transfer after voting, owner plus delegate). Huge ids are fine.
payToonly collects reward on the votes credited to it. - Appeal and swarm — low. The callback doesn't compare the attestation's question hash with the stored one, and doesn't mark the oracle's request id as used (
TaskVault.sol:477). The docs (MECHANICS.md:398) note the plane's hash formula is unverified, which limits the fix. The gas reserve, the 6h timeout and the 3-call cap behave as documented. - YoloPredict — no issue. Points can't overflow (
mulDiv). Settlement is idempotent and the last claimant takes the dust. Positions are blocked during review even without a poke. Zero points happen only for positions under roughlyduration²

Item 5/14. MECHANICS and the task brief state the dev wallet sets YOLO/ETH/IMD prices 'within 10x per step'. _check only compares with the current stored price and there is no delay between steps, so the dev wallet can chain calls in one transaction (or one block) and move a price by any factor.
The only money effect is CaseDesk._stakeBps (the doer stake bonus): with yoloPriceUsd raised 1000x, yoloValue(currency, base) shrinks 1000x, so any lock power >= base/1000 in YOLO gets the full MAX_STAKE_BONUS_BPS (4%). The bonus is taken from the stakers' 5% (treasury + burn), not from users.
Fix: add a minimum interval between price changes (e.g. 1 hour per token) or bound the change relative to a price that is at least N hours old.
claimVoterRewards skips the YOLO add-on voter share when the add-on arrived after submissioncontracts/src/desks/DisputeDesk.sol:441
Item 3/14. s.addon is a snapshot of YoloSweetener.bonusOf(taskId) taken at submit (CaseDesk.submit, s.addon = t.addon). YoloSweetener.sweeten accepts deposits while a submission is under review (it checks only Open and deadline). If the add-on was 0 at submission and is added during the dispute, bonusTask stays 0 and claimVoterRewards never calls YoloSweetener.claimVoter, contrary to its NatSpec ('An accepted submission with a $YOLO add-on also claims payTo's share').
The money is not lost: payTo (or anyone) can still call YoloSweetener.claimVoter(taskId, payTo) directly.
Fix: read the sweetener's bonus/voterVotesLeft at claim time instead of the submission snapshot (e.g. bonusTask = s.taskId whenever outcome is Accepted and a sweetener is bound; the call is already in a try).
Task 1 (1,000 USDC, no add-on).
Doer submits (s.addon = 0).
Disputer disputes; during the vote Carol calls YoloSweetener.sweeten(1, 10,000e18).
NFT holders vote accept, instant decision, appeal window passes -> Accepted; anyone calls payout(1): voterPool = 500e18 YOLO.
Voter V calls vault.claimVoterRewards([subId], V): receives IMD/USDC shares, but YoloSweetener.voterClaimed(1, V) stays false and V receives 0 YOLO from the add-on (expected: V's pro-rata share of 500e18).
Swarm callback does not bind the attestation to the asked question (questionHash) nor consume a.requestIdcontracts/src/TaskVault.sol:477
cancelTask cannot cancel a task whose deadline passed unpoked: it expires first and YoloPredict pays WON'T DO instead of 100% refundscontracts/src/TaskVault.sol:316
Item 6. cancelTask runs _advance before the status check; a task with no active submission and deadline <= now becomes Expired in that call and cancelTask reverts TaskNotOpen.
This matches MECHANICS ('cancelTask of an Open task') and the NatSpec ('still open after its timers are played'), so it is not a rule break, but the dev wallet's cancellation cannot be used to give predictors 100% back once the deadline passed: YoloPredict resolves WontDoWon (5% burn, 5% deferred burned, WILL DO side loses). Contributions, add-ons and bonds still come back through the Expired paths. No fix needed unless the intended rule is otherwise; document it.
Task 1 deadline T. At T+1 (nobody poked) the dev wallet calls cancelTask(1): _advance closes it as Expired and the call reverts TaskNotOpen; YoloPredict.claim pays WON'T DO winners and WILL DO positions get 0 (expected per a reading of 'predictions 100% on cancel': not applicable, the task was no longer cancellable).

Audit mathAgent #205found 1 medium, 1 low, 1 info
Review complete. The findings file holds three substantiated items (one medium, one low, one info); the full non-fork suite passes.
0. VERDICT. Deployable for the math I audited. No critical or high. One medium: a filed appeal can still be asked after its documented 6 h deadline because
askAppealSwarmplays no timers, so the outcome of that step depends on transaction ordering (contracts/src/desks/CaseDesk.sol:274). One low: a doer whose lock ended between submission and payout can re-set it for one week and still collect the stake bonus sized on the old term (contracts/src/YoloLockHub.sol:111). Every bucket split I traced (fee, bonds, voter shares, prediction pools, sweetener, vestings, tax) sums exactly, with dust assigned to a named last claimant or the treasury. Fix the medium before launch; the low is a one-line epoch bump.1. User approvals. Info, no issue. Every pull reads

withdrawTolets a blacklisted USDC recipient redirect, the 30,000-gas buyback send falls back to the burner. The last claimant of every remaining/remaining split takes the exact rest.4. Reentrancy and routing. Info, no issue in my area. Views are forwarded by staticcall without the lock, so the sweetener's callbacks into vault views during a locked claim work.
5. Access rights. Info, no issue.
DevPrices._checkis inclusive at both bounds and reverts on zero.ParamsBoundskeeps every division safe:feeBpsof zero andnftFeeBps == feeBpsgive a zero stakers' part with no underflow.6. Cancel. Info, no issue. Refund buckets are disjoint: contributions, doer bond minus its own spent swarm fee, caller bond plus unspent funds, disputer bond, queued bonds, sweetener, predictions at 100%.

Audit permissionsAgent #967found 1 high, 5 info
The review is complete and the findings file is written. Here is the recap.
Verdict. The permission model holds: no path pulls a user's tokens except from the vault-appended sender, desks accept only the vault or their sibling, the bank is desk-only, and no privileged key can move or redirect user money. One documented rule is broken and is reported with a proof.
Findings written to
.imd-findings.json(6 entries):- High, with Foundry proof. The appeal and swarm-call cap
maxImdInignores the bond's "rew" part when the task reward is IMD. The check inDisputeDesk._fundCallat line 303 compares only the fixed bond plus the fee, yet the 1% reward bond is pulled in the same IMD transfer. The interface and MECHANICS promise "at most maxImdIn IMD". Example state: IMD task with a 1000 IMD reward, a stranger appeals with a 1 IMD cap and 11 IMD leave the wallet. The proof test incontracts/test/scratch/MaxImdInCap.t.solfails on the current code with "next call did not revert as expected" and passes once the cap includes the IMD-denominated rew part. - Info.

One environment note worth passing on: forge 1.8.3 here does not keep constructor transient storage across a later call from the test contract, so standalone tests must deploy the core through one helper contract, which the proof does.

_fundCall (line 292) treats the disputer as 'a side' only when !sidesDoer; a disputer appealing a Reject decision for the doer's side (sidesDoer = true) posts the full second bond and pays the whole fee from the wallet like a stranger. At settlement the stranger fee carve-out excludes any appellant equal to d.disputer, so this caller gets no 0.5 IMD fee back while an unrelated wallet in the same position does.

BuybackBurner.pull lets anyone make the burner call withdraw(address) on an arbitrary targetcontracts/src/BuybackBurner.sol:122

No contract in the repository exposes awithdraw(address)that would move the burner's funds and the burner grants no allowances, so no loss was found; hardening: pin the vault (constructor argument or ProtocolDirectory lookup) rather than taking it from calldata.Any wallet calls burner.pull(X, token) for an arbitrary contract X: X.withdraw(token) runs with msg.sender == burner.
Expected: only the project's vault is called.
Actual: any target is called.

The payTo wallet may later vote itself for the other side (its own side is still 0) and will be paid whichever side wins.

pull(vault, token)takes anyvaultaddress and callswithdraw(address)on it from the burner's own address. The burner holds ETH, USDC, IMD and YOLO and has no approvals, so today no balance can be moved this way (the only selector sent is withdraw(address), which none of the four tokens implements), but the contract issues attacker-chosen external calls under its own identity.Hardening: pin the vault (constructor argument or a dev-set address) or drop

Params.nft and Params.delegateRegistry are not read by the vote path; VotePower's immutables decidecontracts/src/VaultParams.sol:17
The ParamsRegistry comment (and ParamsBounds requiring nft != 0) says a version's
nft/delegateRegistrygovern voting and that address(0) disables delegated votes. DisputeDesk.vote discards those two return values ofvoteParams(DisputeDesk.sol:185(,, uint32 instantDelta, uint32 minWallets) = ...) and checks holders only through the immutableVotePower(nft_, delegateRegistry_)fixed at launch 1.A proposed version with delegateRegistry = address(0) changes nothing. docs/MECHANICS.md 'Trust assumptions' states the VotePower rule correctly; the struct comments and bounds are the drift. No money impact.
Owner proposes and (48h later) activates params identical to version 1 except delegateRegistry = address(0); create a task under version 2; a delegate of an NFT owner (MockDelegateRegistry) votes with the owner's ids.

setBuybackWallet(wallet)(lines 75-80) accepts any non-zero address with no timelock, and TaskVault._burn readsbuybackWallet()at every payout. The DevPrices owner can therefore point every ETH/USDC/IMD burn share (the staked-doer half of the stakers' 5% and the unearned NFT 5%) at a wallet it controls, before or after the share arrives.This is a documented dev power (docs/MECHANICS.md 'Dev wallet' row) and never touches user deposits, rewards or bonds, so it is a trust assumption, not a bypass; the 'cannot send the money anywhere else' wording overstates the constraint. Worst case per stolen dev key: all future burn shares plus whatever sits uncollected in the burner.

Audit judgeAgent #199found 1 high, 1 medium, 4 low, 10 info
The review is complete. The findings file is written and every path, line and snippet matches the tree.
Outcome. I kept 16 entries in
.imd-findings.json, merged from the 20 specialist findings, after reproducing each against the code. No critical issue exists. The verdict entry says the code is deployable once two fixes land.Findings that carry a Foundry proof (each written under
contracts/test/scratch/, self-contained, and failing on this code for the stated reason):- High, DisputeDesk.sol:303.
maxImdInignores the IMD-denominated 1% bond part on IMD-reward tasks. A stranger capping an appeal at 1 IMD has 11 IMD pulled on a 1,000 IMD reward. The interface and MECHANICS promise "at most maxImdIn IMD". Proof:MaxImdInCap.t.sol. - Medium, CaseDesk.sol:274.
askAppealSwarmplays no timers, so an appeal older than the 6-hour ask window is either voided by a poke or asked by a late ask, depending on transaction order. The fee and possibly the final outcome differ. Two specialists reported it at different severities. I merged them and kept medium because a documented rule is broken. Proof:LateAppealAsk.t.sol. - Low, YoloLockHub.sol:111. An ended lock re-set with a 1-week term keeps its epoch, so
stakePowerpays the old 52-week power at the payout. Bounded to 4% of the reward from the stakers' share. Proof:RelockKeepsPower.t.sol.
Kept without proof (reproduced by code reading): the arbitrary-target
BuybackBurner.pull, the sweetener voter share skipped for add-ons made after submission, the DevPrices 10x step with no cooldown, plus nine info entries covering the unboundquestionHash, the disputer-as-stranger fee asymmetry, payTo hedging, the unreadParams.nft/delegateRegistry, the Burned event comment, the unchecked USDC/YOLO bond booking, cancel-after-deadline behaviour, the week rounding, and one merged trust-assumption entry.Dropped or downgraded. Nothing was dropped outright. The three overlapping trust-assumption and access-matrix entries became one info entry, and the two BuybackBurner and two sweetener entries each became one.
Checks run. The full build with via_ir took about 9 minutes. The project's CancelTask suite passed. The full suite was not run inside the time budget. The three scratch proofs all fail as stated. No tracked file was modified. The standalone harness deploys the desks and vault through one helper constructor, since the desks' one-shot wiring flag lives in transient storage and must be raised in the same frame as the vault constructor.
