Repository at commit 84b446c0ff513a39c60486edada40a4a1d781b6b. 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\nKNOWN LIMITATIONS. Every line under Known limitations in docs/MECHANICS.md is an accepted rule, not a finding. Report one only if the documented rule itself is economically abusable: who profits, how much, at what cost, in tokens and $ at a stated reward. Also accepted: the disputer may call the swarm for the doer as an outsider; a winning outsider's 0.5 IMD comes back only from IMD left in the loser's bond; nothing checks that a proof is newer than the task: the burden of proof is the doer's, an old or foreign proof is for the dispute and the swarm.\n\nGOAL. Every high and medium finding with a Foundry PoC; low and info in a separate list at the end, one line each, no PoC needed.\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 every transferFrom, safeTransferFrom and Permit2 pull in contracts/src/ prove `from` is the caller (msg.sender or the vault-appended sender). Can anyone (deployer, owners too) make _fundCall (sender = a.appellant) 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":"5c0c3a64903ff23a208b0d5d368a8bfab61a279c420f7d7a4bd084992afb5bf0","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"30812c29-8868-4f2e-b432-f4ffd11de50c","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":"52158","feedbackHash":"400ab956376f59ebffb57dae49abc5363b9fd25cbe301f9e1a15a7e552ceb8a1","nodeKey":"audit_economics","submissionHash":"9b1ddb6d613e9d75a85f32a226d3d3f85038f0fb7426c2a7c9a4152e4cbda25a","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"50974","feedbackHash":"3e1b55b1f7a4edb2eb74f89698a7f4b2fb4bdadf4be3afefe5b7c835dbdebb7a","nodeKey":"audit_flow","submissionHash":"ecc92fba110647e6f431547ff3ba7b383c8983972bf660cc78b9e4734a16733e","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"51878","feedbackHash":"b4f51c58ec76cc63910da5edb29cdeee1b0d622ff3929601f766c8032e892d07","nodeKey":"audit_judge","submissionHash":"00bc3ce314ed42d994e7754299fade3e0f488fb93db93ca302b7b7f70a9078d0","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"51316","feedbackHash":"90f05419714e661d5b74359812e4b2ecd74ddc4ab8e9d3b04fe38ab3c206a35d","nodeKey":"audit_math","submissionHash":"9169ba35524ecc3a9c2ea328c05c63a63a7da3011b6715b8720829bd5c4957fe","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"52262","feedbackHash":"8aee99b4d3bcb345fc1577c410d5a00c257f179ba42f3d9ffc88377c5225c6c7","nodeKey":"audit_permissions","submissionHash":"b860e4f5a49ee97ae87043d6e83a8180768fbb0b6315ddd0bf1885181b2a5198","tag1":"review:submission","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"0eb660989b1015de9e2e650ad251c620c00b6ef1d181871858a1269c2a5ff500","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":null,"device":"2a6239e0c1b8c774","findings":[{"citation":"resolved","description":"lock(0, weeks_) on a running lock computes pw = max(old + 0, amount * left / 52) where old is the running lock's current power.

Final report follows in the mandatory format.\n\n**0. VERDICT: deployable.** No critical, high or medium found in the economics of `contracts/src/`. Every settlement path conserves value (reward, bonds, add-on, predictions), liabilities move only on money in or out, and the one lock covers vault and desks. Blockers: none. Three low items worth a decision before launch: the dev key (a single EOA) can void a YoloPredict market by `cancelTask` and thereby refund a losing position; the author is paid the whole WILL DO pool on an expiry with no WON'T DO side; `BuybackBurner.forward(ETH)` reverts for exactly the wallet that caused the fallback. Source build passes (warnings only). Test suite not re-run: the via-IR compile of the 60+ test files exceeded the 10-minute background limit on this shared machine.\n\n**1. User approvals.** No issue. Every `transferFrom` in `TaskVault._collect`, `_collectImd`, `collectBondPart` uses `from` = the vault's `msg.sender` or the desk's `_sender()`, which the vault appends itself (`TaskVault.sol:186`), so it cannot be spoofed. `_fundCall` sets `a.appellant = _sender()` before pulling. Desk bank functions are `onlyDesk`; routed desk functions accept only the vault; no delegatecall, no upgrade, no arbitrary call. The swap adapter is approved for exactly `amountIn` and reset to 0. Not reproducible, no PoC.\n\n**2. Balance invariant.** No issue. Books and moves pair up: `_collectImd` books before the pull and reverts on shortfall; `_pay` / `_withdrawTo` / direct burn send reduce liabilities only on success; failed sends become credits. YoloPredict: positions = pools + burnHeld + deferred; Void refunds `paidIn`. YoloSweetener: `bonus = toDoer + burned + toVoters`. YoloLockHub and BuybackBurner hold raw balances only. The only unclaimable remainder is a winner whose own points round to 0 (documented in code, covered by `PredictZeroPoints.t.sol`).\n\n**3. Stuck money.** Low: `BuybackBurner.sol:100` reverts `forward(ETH)` for the same non-receiving wallet that made the vault fall back, so the fallen-back ETH waits for `setBuybackWallet`. Loss bounded to burn shares of staked-doer ETH tasks (0.75% of R), no user money. Fix: credit or skip instead of revert. All user payouts are pull-based credits; a reverting recipient only blocks its own `withdraw`. No PoC needed.\n\n**4. Reentrancy and routing.** No issue. `_entered` is transient and checked by both `nonReentrant` and the forwarding fallback; views are staticcalls without lock. ETH sends from `_pay` happen after state writes; a reentering receiver hits the lock. `onOracleResult` only records. `_sender()` reads the last 52 bytes the vault appended.\n\n**5. Access rights.** Low (finding 1): `TaskVault.sol:369`, the DevPrices owner (a single EOA) may `cancelTask` any open task at any phase. The vault pays the dev nothing, but YoloPredict resolves the market Void (`YoloPredict.sol:271`), refunding a losing position in full. Attack: dev-allied wallet holds WON'T DO 1000 YOLO on a task whose honest submission sits in the 24h window; dev cancels at 23h59m; `claim` returns 1000 YOLO where the correct outcome paid 0. Fix: timelock or multisig on cancel, or exclude markets with an unwound active submission from Void. Documented known limitation says \"takes nothing for itself\", which is true only inside the vault. `wire` is single-use inside the deploy transaction (transient flag). No PoC provided (low).\n\n**6. Cancel.** No issue. Unwound returns pot, top-ups, doer bond minus own swarm spend, appellant bond and unspent fee, disputer bond via `claimDisputer`, queued bonds via `claimVoidSubmission`, add-on via sweetener `withdraw`, positions 100%. No double refund: `_settleNeutral` and `claimDisputer` subtract `sideSpent` exclusively. No user can block cancel.\n\n**7. NFT vote by ids.** Info (finding 6): `DisputeDesk.sol:163`, a `payTo` that only received votes keeps `side == 0` and can vote the other side itself, ending with ","treeHash":null,"usage":{"cachedInputTokens":2821489,"inputTokens":422,"model":"claude-fable-5-1","outputTokens":60320,"runtime":"claude","turns":39,"wallClockMs":1327665}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"28e346843ec15530","findings":[{"citation":"resolved","description":"Permissions audit (items 1,4,5 in depth; 2,3,6,7,8,9,10,13 traced).

The documented formula (`max(old power + added x weeks left / 52, amount x weeks left / 52)`) produces this, so it is reported as the documented rule being gameable, not as a code slip. Smallest fix: when `weeks_ != 0` and `add == 0` (a pure extension), set `pw = all` (amount x weeks left / 52) instead of keeping `old`; keep `old + add * left / 52` only for a pure add with no term change.","line":83,"path":"contracts/src/YoloLockHub.sol","proof":"// SPDX-License-Identifier: MIT\npragma solidity ^0.8.28;\n\nimport {Test} from \"forge-std/Test.sol\";\nimport {YoloLockHub} from \"src/YoloLockHub.sol\";\nimport {MockERC20} from \"../../contracts/test/mocks/MockERC20.sol\";\n\n/// @dev Reproduction of the low finding: after one served 52-week lock, a one-week rolling extension keeps the\n///      full power (amount) while the doc rule for a one-week term is amount / 52.\ncontract LockHubRollingExtension is Test {\n    function test_OneWeekExtensionKeepsFullPower() public {\n        MockERC20 yolo = new MockERC20(\"YOLO\", \"YOLO\", 18);\n        YoloLockHub hub = new YoloLockHub(address(yolo));\n        address alice = makeAddr(\"alice\");\n        yolo.mint(alice, 1000e18);\n        vm.startPrank(alice);\n        yolo.approve(address(hub), type(uint256).max);\n        uint256 t0 = block.timestamp;\n        hub.lock(1000e18, 52);\n        assertEq(hub.power(alice), 1000e18);\n        vm.warp(t0 + 52 weeks - 1 days);\n        hub.lock(0, 1); // one-week extension, nothing added\n        vm.stopPrank();\n        (, uint64 end,) = hub.locks(alice);\n        assertEq(uint256(end), block.timestamp + 1 weeks);\n        // the doc rule \"amount x term in weeks / 52\" gives 1000e18 / 52 for a one-week term; the code keeps 1000e18\n        uint256 oneWeekPower = uint256(1000e18) / 52;\n        assertEq(hub.power(alice), oneWeekPower, \"one-week term should carry one-week power\");\n    }\n}","reproduction":"t0: alice calls lock(1000e18, 52) -> power(alice) == 1000e18, end = t0 + 52 weeks. vm.warp(t0 + 52 weeks - 1 days); alice calls lock(0, 1): newEnd = now + 1 week >= end, left = 1, old = 1000e18, all = 1000e18 * 1 / 52 = 19.23e18, so pw = 1000e18.
