Repository at commit 5f6af8f1052f555553aad41a0e12fc1d29fa90b6. Run forge at the repo root, import as \"src/...\". Modify no existing file; new files only under contracts/test/audit/.\n\nSOURCE OF TRUTH. Rules: docs/MECHANICS.md, then docs/YOLO.md and docs/TOKENOMICS.md. Code: all of contracts/src/. Docs win over comments. Do not re-report what contracts/test/audit/ proves fixed.\n\nSCOPE. Code security only. Payout amounts and role scenarios are separate orders: one info line here.\n\nALREADY FIXED IN THIS COMMIT (passing PoC in contracts/test/audit/): maxImdIn caps the IMD bond part too (MaxImdInCapTest); a late askAppealSwarm reverts (LateAppealAskTest); a 0 bps stake keeps the staked split (StakeFloorZeroSplitTest); stepDeadline while Appealed (StepDeadlineAppealedTest).\n\nACCEPTED BY DESIGN, documented in docs/MECHANICS.md Known limitations. Not findings unless the code differs from the documented rule: 20+ NFTs disputing from a second wallet; undisputed in 24 h = accepted, WON'T DO predictors dispute; an appeal not asked in 6 h void, full refund, new 24 h window; the queue judged in turn; one dispute per submission; cancelTask in any open phase, spent swarm fees kept; a started YoloLockHub week counted whole.\n\nREPORT FORMAT, MANDATORY. One entry per item, same order, even \"no issue\"; a missing item = INCOMPLETE. Entry 0: VERDICT, deployable or not, every blocker, max 8 lines. Items 1-14: severity, file:line, attack (who calls what, when), loss in tokens at a stated reward, smallest fix, and a Foundry PoC (full source, contracts/test/audit/, fails now, passes once fixed, no fork, no ffi) if real, else one line why not. Severity: critical = theft, permanent loss or freeze, a privileged wallet taking or redirecting user money; high = loss under realistic conditions or a documented rule broken; medium = bounded loss or cheap griefing; low = edge case; info = drift, hardening, \"no issue\".\n\n1. USER APPROVALS. No path takes a user's tokens without their own call. For each pull (TaskVault.sol:555, 696, 769, 787, YoloSweetener.sol:102, YoloPredict.sol:167, YoloLockHub.sol:85, DareTrophy.sol:114, adapters/UniswapV3SwapAdapter.sol:65) prove `from` is the caller (msg.sender or the vault-appended sender). Can anyone (deployer, owners too) make _fundCall (sender = a.appellant, :291) pull from another wallet, spoof the sender via vault forwarding, or spend an allowance or Permit2 signature via admin, upgrade, delegatecall or arbitrary call? Any such path = critical.\n2. BALANCE INVARIANT. TaskVault books every amount in one bucket; liabilities[token] = their sum <= balance. Find a path that books without moving money, moves without booking, books twice, or leaves a bucket nobody can claim. Same per market in YoloPredict (claims + burned + deferred + dust == positions), YoloSweetener, YoloLockHub, BuybackBurner.\n3. STUCK MONEY. Every pull payment ends paid. Rewards in ETH, USDC (blacklisted recipient), IMD, YOLO; reverting or gas-eating ETH receivers; the 30,000-gas send to the buyback wallet and its fallback. Can one party's revert block another's payout?\n4. REENTRANCY AND ROUTING. One lock covers vault and desks; the vault forwards selectors with the sender appended (_route, Desk.routed, _sender). Reach a desk function meant only for the vault or reenter via ETH sends, tokens, onOracleResult, the delegate registry or ownerOf?\n5. ACCESS RIGHTS. Rules: the vault has no owner. The ParamsRegistry owner changes parameters for future tasks only, inside ParamsBounds, after 48 h (same for swarm-answer attesters), pauses new task creation only, binds the Sweetener once. The dev wallet (DevPrices owner of the task's version) sets the YOLO, ETH and IMD prices by hand within 10x per step (USDC = $1), sets the buyback wallet, may cancel an open task. ProtocolDirectory, HiddenList, TrophyCatalog hold no money. Worst case in money for each stolen key. wire callable twice or by anyone?\n6. CANCEL. cancelTask in every phase (no submission, dispute window, voting, appeal filed, swarm silent, queue, deadline passed with timers not played). Rule: everyone takes back what he put in (reward, top-ups, YOLO add-ons, all bonds, unspent prepayment, queued doers, predictions 100%); paid swarm fees stay gone; the dev wallet gets nothing. Double refund, missed party, cancel blockable by a user?\n7. NFT VOTE BY IDS. DisputeDesk.vote(subId, side, payTo, tokenIds), VotePower: ids owned now or delegated (delegate registry v2); each id once per dispute; side fixed; several transactions per side; power = ids; own transaction only. Break: one id twice (repeat, transfer, owner plus delegate), a lying ownerOf, payTo tricks, the minimum-wallets count, an instant decision racing a late vote.\n8. APPEAL AND SWARM. appeal, askAppealSwarm, callSwarm, _fundCall, CaseDesk._ask, TaskVault.ask/onOracleResult, AttestationChecker. Rules: anyone appeals; a dispute party pays the fee from its bond, an outsider posts bond plus fee, capped by maxImdIn; the question goes out in a later call by anyone; max 3 swarm calls per submission; a failed ask, or an appeal not asked within 6 h, counts and refunds. Break: forged or replayed answer, answer after a cancel, gas starvation of an ask (ASK_GAS_RESERVE), price change before the ask.\n9. YOLOPREDICT. predict, settle, claim, _split, _points. Rules: YOLO only, irrevocable, before the deadline, paused during review; 5% burn held to the outcome, 5% deferred, 90% pool, points = amount x ((deadline - now)/(deadline - creation))^2; Unwound = full refund. Break: a position during review, points overflow or zero, last-claimant dust, double settle.\n10. YOLOLOCKHUB. lock(add, 1..52 weeks), withdraw after the end, checkpoints, epoch; CaseDesk reads powerAt at submission (any power, no threshold), DisputeDesk re-checks stakePower at payout. Break: withdraw and relock keeping the bonus, extend-plus-add gaming, lost or double-withdrawn balance.\n11. ROUNDINGS. Bonds (0.5 IMD + 3% or 1% of the author's own reward), stake share in bps, fee splits, prediction splits, voter shares: direction, who gets dust, a last claim that reverts.\n12. DOS AND GAS. Unbounded loops, tiny top-up griefing, block gas limit on must-succeed paths, vote and claim at 2,000 NFTs; gas waste over 20% on a hot path.\n13. TOKEN AND SIDE CONTRACTS. token/ (YoloToken first-hour buy and sell tax only on Uniswap v4 PoolManager transfers, NftGate, vestings, YoloSplitter), DareTrophy (7,777 YOLO burned per mint). TrophyCatalog: owner-only designs, a minted trophy keeps its design. Locked or stealable balances, time math at openAt.\n14. COMMENTS VS CODE. Each promise the code does not keep, one line, info.\n15. COVERAGE. Files read in full, what was not reached, forge build and test result.\n\nNot findings: test/mocks; placeholder wallets; legal; brand/, landing/; Intake, Uniswap, delegate registry, IMD factory themselves. By design unless worse than stated: self-dispute from a second wallet; one late position taking the other side; many wallets in predictions; one lock for all submissions; a stale dev price moving only the stake bonus; ERC-6909 buys before openAt; untaxed v2/v3 pools; fees of silent swarm calls kept.\n","parentJobId":null,"planHash":"6baac64556fe8cfb9db3076b675f7cdb16a4a2332cc17e920222f76899691d75","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"afb75675-216c-48d8-9984-452e2869aa25","publication":{"commit":null,"deliveredAt":null,"repoUrl":null},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"51352","feedbackHash":"f432bd11770310a5f572c42dc4888c6e791f94ef9def2bfa359bb4b355e895b4","nodeKey":"audit_economics","submissionHash":"ec9e4d8327e7347413e71f53f0a121cf7d36090d8e491a703881a28f3d920d50","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"53910","feedbackHash":"ffeecc24614d2cbc7917ad0a747156f6ac2dd51687f588f69a35d26bd3cef257","nodeKey":"audit_flow","submissionHash":"64031d5f07630b5082f3f48c334ebe84308bde32fde19774ceae1fd7820e3427","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"51232","feedbackHash":"766d6a1f50f7af2ca252bbbd2ca2f87be712b405986eae190915ae688a5cf6c8","nodeKey":"audit_judge","submissionHash":"4b6342f7575b9b9ba8eb6e494fcd2e35e4fe7bc983f4485c8141e3e0a2174f65","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"52179","feedbackHash":"2272e79fd3818fb76e177b1008dc21e1a8521424f994946f3b73493e47cf3a98","nodeKey":"audit_math","submissionHash":"1abb4a4609b735c671192074b7e4d502093be61396d3c226dd928d524acdaa40","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"52678","feedbackHash":"3bc5db638e69ceee89d214fff1155e945933243e960cf090f576cf45bd2ed7e6","nodeKey":"audit_permissions","submissionHash":"8adf3b72a5935d0c18b5e1dec0c922ae24d87bf2808effc6e50dca414e1ea1f6","tag1":"review:submission","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"3de286d62bd10fbd03ab048b7cf51eb46f0f7cf9a3f50f080856cdee4322780a","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":null,"device":"02f22d6f13810ca8","findings":[{"citation":"resolved","description":"stakePower only rejects a lock whose epoch changed (a withdrawal) or whose end has passed.

Bonds, fee splits, voter and disputer shares, prediction points and splits, the token tax curve, vesting streams and the lock power formula all round in the documented direction, with the last claimant taking the dust and no path I could find that books without moving money or strands a bucket. I recorded two items in `.imd-findings.json`.\n\n- **Low, YoloLockHub.sol:111.** A doer's lock that ends between the submission and the payout can be re-armed with a one-week term and no new tokens. The epoch only changes on withdrawal, so the payout check still returns the full submission-time power while the live lock is worth 1/52 of it. The doer keeps the up-to-4% stake bonus while committed to only one week. A scratch test demonstrates the state. The smallest fix is to bump the epoch in `lock` when the previous term had ended.\n- **Info, DisputeDesk.sol:641.** The comment promises a winning stranger appellant 0.5 IMD off the top of the loser's bond. When the losing side's own bond already paid a silent swarm call, the IMD penalty is zero and the refund silently drops. Docs do not promise this, so it is a comment-versus-code note.\n\n**Checked and found consistent with the docs.** Points flooring to zero only with sub-second remaining time at the 1 YOLO floor.

In `_settleDecided`, when the swarm sides with the doer, that same wallet is the winning caller: `winnerBonds = doerBond + a.bond` and `_splitCurrency` credits `appPart = winnerShare * a.bond / winnerBonds` to the disputer out of the penalty that is the disputer's OWN forfeited dispute bond (`appellantIsStranger` is false, so no 0.5 IMD carve-out, but the pro-rata split still runs). If the swarm sides against the doer instead, the disputer is the sole winner and `claimDisputer` returns the lost caller bond in full (penalty = doer bond + the caller's bond, 100% to the disputers). So a disputer who expects to lose hedges for one swarm fee: instead of forfeiting the whole dispute bond to the doer they claw back half of the IMD penalty (0.25 of 0.5 IMD) and a quarter of the reward-currency penalty (1% vs 3% weights).

The payout rule (docs/MECHANICS.md 'Doer stake condition': `stakePower(doer, submittedAt)` must not be 0, 'the same lock, never withdrawn, still running'; desks/DeskApi.sol:110: '0 once that lock ended or was withdrawn') is enforced only through `epoch`, which grows in `withdraw()` alone. `lock()` on a lock whose `end` passed starts a new term with `old = 0` (the comment at line 65: 'a lock set again starts afresh') but keeps `l.epoch`, so `_pointBefore(who, since)` still finds the original point (same epoch, `p.end > since`) and `l.end` is in the future again: `stakePower` returns the ORIGINAL power although the lock behind the submission ended and the new term may be a one-week lock of the same tokens. A doer whose lock lapses during a long case (dispute, vote, appeals) restores the up-to-4% bonus with one cheap `lock(0, 1)` call right before the finalizing poke, while a doer who withdrew loses it. Bounded: at most 4% of R, taken from the stakers' 5% fee share (half burn, half treasury), and the tokens stay in the hub, so low.

Two specialists merged.\n- **Fourteen info entries.** Comment drifts (Appeal.spent, Contribution.ever, Burned event, dispute ETH pot, quoteSubmission add-on, stranger fee cap, dead nft/delegateRegistry params), hardening notes (BuybackBurner.pull arbitrary call, attester proposals never expire, `_trySend` code-less token), the dev-key trust assumption, the poke-time dependence of the stake bonus, the zero-point YoloPredict edge, and the required scope line on payout amounts.\n\n**Judgement calls.** BuybackBurner.pull was downgraded from low to info: no approvals, no value, no reachable loss. The medium carries no self-contained proof because a proof needs the fixture's mocks, which the proof rules forbid importing; the reproduction states the exact calls and numbers instead.

Here is the report.\n\n**Entry 0: VERDICT**\nDeployable. No blocker found. All 40 source files under contracts/src/ were read in full; forge build passes and 670 of 671 unit tests pass (1 skipped by the suite itself, fork tests not run). Eight extra probe scenarios (disputer appealing for the doer side, doer appeal above the bond, cancel during Appealed and Asked, ETH task with a losing stranger caller, payTo voting the other side, 2,000-id vote, YoloPredict no-winner) all left the vault exactly solvent with nothing stuck. One low hardening item (BuybackBurner.pull) and six info items are in .imd-findings.json. Payout amounts and role scenarios are separate orders.\n\n**1. User approvals.** Info, no issue. Every pull uses the caller: createTask/topUp pass msg.sender; the desks pass the vault-appended sender (last 52 bytes of calldata, appended after the full msg.data so it cannot be spoofed); _fundCall's a.appellant was just set to that sender; YoloSweetener, YoloPredict, YoloLockHub, DareTrophy and the adapter pull from msg.sender. Bank functions are onlyDesk, desk functions are routed or only(sibling); no delegatecall, no upgrade, no arbitrary call reaches an allowance.\n\n**2. Balance invariant.** Info, no issue. Settlements are credit-only moves between buckets; liabilities change only at collect, pay, ask and refund. The probe scenarios end with liabilities equal to zero and balance equal to liabilities for all four tokens. YoloPredict void refunds paidIn while burnHeld and deferred are zeroed without transfer; the contract ends at zero.\n\n**3. Stuck money.** Info, no issue. Every push falls back to a credit, including the 30,000-gas buyback send which falls to the burner. One info hardening item: _trySend treats a code-less token as success (TaskVault.sol:754), unreachable with the three immutable tokens.\n\n**4. Reentrancy and routing.** Info, no issue. One transient lock covers fallback-forwarded calls, poke, cancel and withdraws; onOracleResult is gated by the stored Intake and makes only a view call; a late vote after an instant decision reverts WrongPhase (observed).\n\n**5. Access rights.** Low: BuybackBurner.pull makes an arbitrary outbound call from a money-holding contract (BuybackBurner.sol:122); no loss today. Everything else matches the stated rules; wire works once and only inside the deployment transaction.\n\n**6. Cancel.** Info, no issue. Cancel during Appealed and Asked refunds bond and unspent prepayment, keeps spent fees, and the task ends solvent; nobody can block it.\n\n**7. NFT vote by ids.** Info, no issue. Per-id bitmap stops repeats, transfers and owner-plus-delegate; side fixed per wallet; payTo accounting balanced in the probe.\n\n**8. Appeal and swarm.** Info, no issue. Fixes for maxImdIn and the late ask hold; the live Intake v2 returns a 4-word requests() tuple (checked by eth_call on Ethereum mainnet, public RPC), so the try/catch decode in _swarmStatus is safe; price is 0.5 IMD.\n\n**9. YoloPredict.** Info: the no-winner branch keys on points, not amounts (YoloPredict.sol:209); unreachable at realistic sizes.\n\n**10. YoloLockHub.** Info: the bonus depends on when the payout is poked (YoloLockHub.sol:111), verified 7 bps vs 0 bps in the fixture; the doer can self-poke.\n\n**11. Roundings.** Info, no issue. All last claimants take the remainder; dust with no winner bond goes to treasury.\n\n**12. DoS and gas.** Info, no issue. A 2,000-id vote measured 8.5M gas, under the 16.7M cap; no unbounded loop on a must-succeed path.\n\n**13. Token and side contracts.** Info, no issue. Tax math matches the documented 30 into pool, 30 to treasury; vesting clocks start at the split; trophies burn 7,777 YOLO and keep their design id.\n\n**14. Comments vs code.** Info: dispute ETH pot comment (TaskVault.sol:49), Contribution.ever comment (VaultTypes.sol:181), Burned event routing (VaultTypes.sol:364).\n\n**15.

At settlement `_settleDecided` then counts that same wallet as the winning caller whenever the swarm sides with the doer: `winnerBonds = doerBond + a.bond`, and `_splitCurrency` credits `appPart = winnerShare * a.bond / winnerBonds` to the disputer out of the penalty that is the disputer's OWN forfeited dispute bond.

Attack: doer locks A YOLO for 52 weeks near the end of a term (or any lock that ends during the judging of the submission), submits, lets the lock end while the case is in dispute/vote/appeal, then calls `lock(0, 1)` (no new tokens, one week) before the final `step`; `_lockRuns` sees a non-zero `stakePower` and `_payReward` pays `bonus`. Loss at R = 100 USDC with full power: 4 USDC that should have gone 2 USDC burn + 2 USDC treasury (bounded by the fee, hence low). Smallest fix: bump `epoch` whenever a term is started on a lock that is not running (in `lock()`, when `end <= block.timestamp` before the new term is set), or return 0 in `stakePower` when the point's `end <= block.timestamp`.
