Nothing in the repository was changed or deployed. ## Findings ### 1. Low: ClausNativeVault's fixed 250,000 policy gas cannot read a configuration above ~3.5 KB, so an admitting policy is reported as DepositDenied `contracts/src/ClausNativeVault.sol:15` ``` uint256 public constant POLICY_GAS = 250_000; ``` ClausNativeVault._admitted forwards a constant POLICY_GAS (250,000) to the admission policy via staticcall (line 70). The policy is a ClausReadonlyProject whose evaluate() first copies its whole stored `configuration` from storage to build the module calldata (ClausReadonlyProject.sol:39) and then forwards a further fixed 200,000 gas to the module (line 45). Both the executor (registerProject/execute, 8192-byte cap) and the project (_apply) permit configurations up to 8,192 bytes, i.e. 256 cold SLOADs at ~2,100 gas each, so the policy's own gas need scales with configuration size while the vault's budget is constant. Above roughly 3,488 bytes the staticcall runs out of gas, `success` is false and _admitted returns false: every deposit reverts DepositDenied even though the module returns (true, max) when called directly. Nothing distinguishes this from a genuine denial. Withdrawals never call the policy and are unaffected, so the impact is a fail-closed denial of all new deposits that a Claus-approved policy upgrade can trigger unintentionally and that only another approved upgrade to a smaller configuration can repair. The shipped ClausVaultAdmission requires exactly 64 bytes, which is why the pilot has not observed it; the gap is between the two bounds the system enforces (8,192-byte configuration vs 250,000 gas). Minimal fix preserving the design: size POLICY_GAS so the maximum permitted configuration plus the 200,000 module allowance fits (roughly 800,000), or derive the budget from the policy's configuration length, and distinguish a failed policy call from a policy that returned false (separate error). **Reproduction** Deploy LenientAdmission (module returning abi.encode(true, type(uint256).max) for any configuration), register it in a ClausReadonlyProject with configuration = new bytes(4096), deploy ClausNativeVault(policy), fund an EOA and call deposit{value: 1 ether}(). Expected: policy.evaluate(abi.encode(account, 1 ether, 1 ether)) returns (true, max) when called directly, so the deposit is credited (principal == 1 ether). Actual: deposit reverts DepositDenied. With configuration = new bytes(64) the same deposit succeeds. Reproduced with the attached test (forge test --match-path test/scratch/ProofVaultGas.t.sol: testAdmittingPolicyWithLargeConfigurationCreditsDeposit FAILS with DepositDenied(), testSmallConfigurationStillAdmits passes). The specialist's binary search places the boundary at 3,488 admitted / 3,520 denied bytes under solc 0.8.27, via-IR, cancun. **Proof**: a Foundry test that fails on this code and passes once it is fixed. ```solidity // SPDX-License-Identifier: MIT pragma solidity 0.8.27; import {Test} from "forge-std/Test.sol"; import {ClausNativeVault} from "src/ClausNativeVault.sol"; import {ClausReadonlyProject} from "src/ClausReadonlyProject.sol"; /// Admission module that accepts any configuration length and always admits. contract LenientAdmission { function evaluate(bytes calldata, bytes calldata) external pure returns (bytes memory) { return abi.encode(true, type(uint256).max); } } /// Fails on the current code: a policy project with a 4,096-byte configuration admits the /// deposit when evaluated directly, but ClausNativeVault's fixed POLICY_GAS (250,000) is not /// enough to read that configuration from storage, so the vault reports DepositDenied. /// Passes once the vault's policy gas budget covers the configuration sizes the project allows. contract VaultGas is Test { function testAdmittingPolicyWithLargeConfigurationCreditsDeposit() public { LenientAdmission m = new LenientAdmission(); ClausReadonlyProject pol = new ClausReadonlyProject(bytes32(uint256(1)), address(m), new bytes(4096)); // The policy itself admits. bytes memory out = pol.evaluate(abi.encode(address(0xA11CE), uint256(1 ether), uint256(1 ether))); (bool allowed, uint256 max) = abi.decode(out, (bool, uint256)); assertTrue(allowed); assertEq(max, type(uint256).max); ClausNativeVault v = new ClausNativeVault(address(pol)); address alice = address(0xA11CE); vm.deal(alice, 1 ether); vm.prank(alice); v.deposit{value: 1 ether}(); // reverts DepositDenied on the current code assertEq(v.principal(alice), 1 ether); assertEq(v.totalPrincipal(), 1 ether); } function testSmallConfigurationStillAdmits() public { LenientAdmission m = new LenientAdmission(); ClausReadonlyProject pol = new ClausReadonlyProject(bytes32(uint256(1)), address(m), new bytes(64)); ClausNativeVault v = new ClausNativeVault(address(pol)); address alice = address(0xA11CE); vm.deal(alice, 1 ether); vm.prank(alice); v.deposit{value: 1 ether}(); assertEq(v.principal(alice), 1 ether); } } ``` ### 2. Low: revokeGrant and project disablement leave the revoked publisher's record as latest() for up to 24 hours `contracts/src/ClausSignalStore.sol:120` ``` grants[id].revoked = true; ``` revokeGrant is the owner's only emergency lever against a misbehaving publisher, but it only sets grants[id].revoked. The single `record` written by that publisher is returned unchanged by latest(); Record has no retracted flag and the store exposes no owner function to clear or expire it. Disabling the project via ClausApprovalExecutor.setAuthority(id, mandate, false) also leaves latest() unchanged (it only blocks new publishes through _project(true)). A consumer following the documented freshness check (validUntil) keeps accepting the revoked publisher's data until validUntil, which may be up to MAX_DATA_LIFETIME (1 day) after observedAt. The owner's only workaround is to register a new grant to a key it controls and publish a corrective record that itself passes the evaluator, which also requires the project to be enabled. docs/signals.md states that published data cannot be erased, but presents onchain revocation as the way to remove a publisher's authority; the latest record keeps that authority's effect alive. Minimal fix within the design: in revokeGrant, if record.grantId == id, set record.validUntil = uint64(block.timestamp) (or clear the record) and emit an event, and/or expose the grant's revoked flag next to latest() so consumers can check both in one read. **Reproduction** State: store bound to the Pulse evaluator (threshold 1 gwei, maximumAge 3600); owner registers grant G to publisher P (maximumWrites 100, interval 1, expiresAt now+2d). 1) P calls publish(G, 1, 1, now, now+3600, keccak256('src'), validPulseData): latest().sequence == 1, validUntil == now+3600. 2) Owner calls revokeGrant(G): grant(G).revoked == true. 3) latest(): expected a retracted record or validUntil <= now; actual sequence 1, grantId G, validUntil still now+3600, output unchanged. 4) Owner calls executor.setAuthority(projectId, MANDATE, false): latest() is still the same record. Reproduced in test/scratch/Leads.t.sol::testRevokedRecordStaysLatestAndBogusHashAccepted (passes on current code, asserting the stale record). ### 3. Low: Cancelling an owner-transfer proposal (or any setAuthority call) bumps authorityGeneration and permanently disables every publisher grant `contracts/src/ClausApprovalExecutor.sol:189` ``` ++p.authorityGeneration; ``` proposeProjectOwner increments authorityGeneration unconditionally, including when nextOwner == address(0), which the NatSpec and README describe as cancelling the proposal; setAuthority (line 172) increments it on every call, including re-enabling with an unchanged mandate. For the executor itself this is intended invalidation of in-flight approvals. ClausSignalStore, however, binds each PublisherGrant to the exact authorityGeneration at registration and publish reverts GrantInactive on any mismatch (ClausSignalStore.sol:134). So an owner that proposes a transfer and then cancels it, as the README instructs ('Cancel stale owner-transfer proposals explicitly'), ends with upgrades restored (enabled still true, pendingProjectOwners cleared, same owner) but every grant on every store of the project dead for the rest of its term, with no way to revive it: each publisher needs a fresh owner-signed grant and nonce, and the old grant's remaining writes are stranded. docs/signals.md only says 'an owner or authority change invalidates old grants'; neither a cancelled proposal nor a re-affirmed mandate is an owner or authority change. Owner-triggered, so no permission bypass; reported as an operational hazard and documentation gap. Options that preserve the design: skip the increment when nextOwner == 0 and no proposal is pending (and for a no-op setAuthority), or document that any proposal/cancel cycle requires re-granting all publishers. **Reproduction** State: project registered (authorityGeneration 1), store deployed, grant G to publisher P registered with authorityGeneration 1. Owner calls executor.proposeProjectOwner(projectId, 0x77) then executor.proposeProjectOwner(projectId, address(0)). executor.projects(projectId) now reports owner unchanged, enabled == true, authorityGeneration == 3, pendingProjectOwners == 0. P calls sink.publish(G, 1, 1, now, now+300, keccak256('src'), validPulseData). Expected: DataPublished, since the proposal was cancelled and nothing about ownership or mandate changed. Actual: revert GrantInactive(), and the grant stays inactive for its remaining life. Reproduced in test/scratch/Leads.t.sol::testCancelProposalKillsGrants. ### 4. Low: deliverCallback allows unlimited full-gas retries against a requester whose callback always fails, so an automated deliverer can be made to burn ~1M gas per attempt `contracts/src/ClausRequestInbox.sol:101` ``` if (!delivered) r.callbackDelivered = false; ``` deliverCallback is permissionless and, on a failed callback, resets callbackDelivered to false so the same id can be retried without bound. Nothing records the number of attempts, the requester pays nothing for delivery, and the guard at line 95 (gasleft() >= limit*64/63 + 50,000) forces the deliverer to bring the full callbackGas every time, so it cannot cap its own exposure on-chain. A requester contract that registers callbackGas = MAX_CALLBACK_GAS (1,000,000) and implements onClausResult as an infinite loop makes every attempt cost about 1.04M gas and leave the request retryable. Attacker cost is one request event (tens of thousands of gas); deliverer cost is ~1.04M gas per attempt, repeated as long as its automation retries. Who loses: whoever operates an automatic deliverer (the README describes sponsored requests and the reference client relies on inbox-delivered results). The deliverer can mitigate off-chain by not retrying after CallbackAttempted(id, false), which is why this is low rather than medium. Minimal on-chain fix within the design: record a failed-attempt flag or counter and require the requester (or an explicit opt-in) to re-arm retries, or let the deliverer pass a lower gas limit and record it. **Reproduction** Deploy ClausRequestInbox(dispatcher). Deploy requester R whose onClausResult(bytes32,uint8,bytes,bytes32) is `while (true) {}` and have R call inbox.request(keccak256('b'), keccak256('c'), now+1 day, 1_000_000, 'in') -> id. Dispatcher calls resolve(id, true, keccak256('e'), 'out'). Anyone calls deliverCallback{gas: 1_200_000}(id, 'out') three times. Expected: a bounded delivery cost or a terminal failure state after the first attempt. Actual (measured in test/scratch/Leads.t.sol::testDeliverCallbackUnboundedRetries): each call returns delivered == false, consumes 1,040,256 / 1,042,756 / 1,042,756 gas, and requests(id).callbackDelivered is false after every attempt; deliverCallback{gas: 900_000} reverts CallbackGasUnavailable, so the deliverer cannot send less. ### 5. Info: Signal store and factory reject code-bearing owners and publishers that the approval executor accepts (ERC-1271 wallets, EIP-7702 delegated EOAs) `contracts/src/ClausSignalStore.sol:99` ``` if (owner.code.length != 0 || g.publisher == address(0) || g.publisher.code.length != 0 || ``` Merged from three specialist reports. ClausApprovalExecutor.registerProject verifies the owner with SignatureChecker.isValidSignatureNow (line 134), so a project may be owned by an ERC-1271 contract wallet, and the README allows 'deliberately reviewed ERC-1271 verification'. ClausSignalStore.registerGrant (line 99) and ClausSignalFactory.create (ClausSignalFactory.sol:23) revert whenever owner.code.length != 0, and publish (line 133) reverts whenever msg.sender.code.length != 0. docs/signals.md line 34 documents this exactly: 'Owner / publisher: EOA only; contract wallets and EIP-7702 are not admitted', so the exclusion is a stated design choice, not a defect, and the specialists' claim that it is undocumented does not hold. The residual points, all verified: (1) the executor admits a contract owner that can never obtain a store or grant, and nothing signals that at registration; (2) an EOA owner or publisher that later attaches an EIP-7702 delegation (23-byte designator 0xef0100||addr, live on Sepolia and mainnet since Prague) is still the owner for setAuthority/proposeProjectOwner/revokeGrant/cancelGrantNonce but can no longer registerGrant, create or publish, so an existing store can only shrink its publisher set and a delegated publisher's remaining writes are stranded; (3) the code-length check is not what prevents contract-signed grants, ECDSA.recover already does. No funds at risk. If the EOA-only rule is kept, add the signals.md restriction beside the README's ERC-1271 statement and consider accepting or explicitly documenting 7702 designators; if alignment is preferred, use SignatureChecker in registerGrant and drop the owner.code.length checks. The specialist proof (Proof_6ce8ba77f798) fails on current code with InvalidGrant() as described but is not attached, because making it pass would contradict the documented EOA-only design. **Reproduction** State: project registered with EOA owner vm.addr(0xB0B), store deployed, owner signs Grant(publisher 0xBEEF, authorityGeneration 1, maximumWrites 2, minimumInterval 60, expiresAt now+1d, nonce 0). vm.etch(owner, 0xef0100||0x1234) (code.length 23). executor.projects(projectId).owner is still the delegated address. sink.registerGrant(g, ownerSig): expected PublisherGranted (ECDSA key unchanged), actual revert InvalidGrant(). factory.create(projectId, FEED, SCHEMA) from the owner: actual revert InvalidProject(). A publisher that delegates after its grant was registered gets PublisherOnly() from publish. Reproduced by running the specialist proof as test/scratch/ProofDelegated.t.sol (fails with InvalidGrant()). The ERC-1271 variant: register a project with an OwnerWallet whose isValidSignature returns 0x1626ba7e, then factory.create from it reverts InvalidProject (ClausSignalFactory.sol:23). ### 6. Info: Session renewal resets spent, so a pre-signed next generation can be submitted by anyone while the current generation is unspent and totals accumulate `contracts/src/ClausProjectWallet.sol:94` ``` sessions[s.sessionId] = Session(s.signer, s.asset, s.recipient, s.perPayment, s.total, 0, ``` authorizeSession is permissionless given an owner signature and only requires generation == stored generation + 1; it writes a fresh Session with spent = 0. If the owner pre-signs generation N+1 as a renewal, any holder of that signature (including the session signer or recipient) can submit it while generation N is still valid, so the amount extractable under one session ID is the sum of every signed generation's total, not the latest total. The owner does control this through validAfter and deadline on each authorization, and every payment still needs the session signer's signature and stays asset- and recipient-bound, so this is a key-management and disclosure point rather than a bypass. The README documents that nonces persist across generations and that revocation retires the ID, but not that spent resets on renewal. Suggested: document that a renewal's total is additive to any unspent prior generation, or carry spent forward (or require the prior generation to be expired or exhausted) when the renewal keeps the same recipient and asset. **Reproduction** State: wallet W (owner O) holds 10 ETH. O signs S1 = {sessionId X, signer K, asset 0, recipient P, perPayment 1 ETH, total 1 ETH, validAfter 0, validUntil now+10d, generation 1, deadline now+10d} and S2 identical with generation 2. authorizeSession(S1); pay(1 ETH, nonce 1, gen 1): P receives 1 ETH; a second gen-1 payment reverts InvalidPayment (total reached). An unrelated address 0x1234 calls authorizeSession(S2, sigO); pay(1 ETH, nonce 2, gen 2) succeeds. Expected if total were a per-session-ID cap: the second payment is rejected. Actual: P has received 2 ETH under session X. Reproduced in test/scratch/Leads.t.sol::testRenewalResetsSpent. ### 7. Info: Pinned module codehash does not detect behaviour changes of a proxy or delegating module (documented trust assumption, verified on chain) `contracts/src/ClausReadonlyProject.sol:38` ``` if (implementation.codehash != implementationCodeHash) revert InvalidModule(); ``` The executor and kernel pin the module by EXTCODEHASH at registration, approval and every evaluation. A module whose bytecode dispatches to an address held in its own storage keeps the same codehash while its executing logic changes, so 'installed behaviour can only change through a Claus-signed approval' is not an on-chain property for such modules. README and AUDIT_RESPONSE already state that proxy and EIP-7702 delegated modules are outside the supported profile and must be rejected by the off-chain reviewer and approval policy; this entry records that the contracts do not enforce that rejection, so it is an off-chain assumption. No change required if the off-chain rejection is retained. Optional hardening: reject modules whose runtime code contains DELEGATECALL/CALLCODE or begins with the 0xef0100 designator in registerProject and _validate, at the cost of also rejecting legitimate library-style modules. **Reproduction** State: MutableProxy P (admin A, impl ModuleA returning abi.encode(1)) registered as the implementation of project T with codeHash = P.codehash; no Claus approval since. Input: A calls P.setImpl(ModuleB) where ModuleB returns abi.encode(2); then T.evaluate(''). Expected under the stated exact-code property: InvalidModule or the originally reviewed result 1. Actual: T.implementationCodeHash() == P.codehash still holds and T.evaluate('') returns 2 with no executor transaction, approval or event. Reproduced in test/scratch/Leads.t.sol::testProxyModuleChangesBehaviour. ### 8. Info: ClausPulseModule accepts an arbitrary block hash for blocks that blockhash() could still verify `contracts/src/ClausPulseModule.sol:23` ``` if (chainId != context.chainId || number == 0 || hash == bytes32(0) || timestamp != context.observedAt || ``` The module validates chainId, observedAt freshness and validUntil, but never compares `hash` to blockhash(number) even when number is within the last 256 blocks, where the EVM can verify it at no external cost. A granted publisher can therefore attest a fabricated hash for a very recent block and it is stored and emitted in DataPublished as observed. The docs already state that publishers attest the input, so this is a missed cheap hardening, not a broken guarantee; baseFeeWei cannot be verified on chain either way. Suggested: when block.number > number && block.number - number <= 256, require hash == blockhash(number); keep attestation semantics for older blocks and state the boundary in the schema docs. **Reproduction** State: store with Pulse evaluator (threshold 1 gwei, maximumAge 3600), grant G to publisher P, block.number == 1000. Input data = abi.encode(block.chainid, uint64(999), keccak256('bogus'), uint64(block.timestamp), 2 gwei). P calls publish(G, 1, 1, now, now+3600, keccak256('src'), data). Expected if the module verified recent blocks: revert InvalidObservation because blockhash(999) != keccak256('bogus'). Actual: publish succeeds and abi.decode(latest().output) returns (999, keccak256('bogus'), 2 gwei, true). Reproduced in test/scratch/Leads.t.sol::testRevokedRecordStaysLatestAndBogusHashAccepted. ### 9. Info: deliverCallback has no deadline: any party can push a resolved result into the requester's callback arbitrarily late `contracts/src/ClausRequestInbox.sol:88` ``` if ((r.state != State.Completed && r.state != State.Failed) || r.callbackDelivered ``` request() bounds resolution by deadline (<= 30 days), but once a request is Completed or Failed the callback can be delivered by anyone at any time; there is no callback deadline and the requester cannot opt out after resolution (cancel only works while Pending). A third party therefore chooses when onClausResult runs, including years later. The data is authentic (hash-bound) and ClausRequestClient._record is idempotent, so for the reference client the impact is timing only; a requester with time-sensitive callback logic must enforce its own deadline. Suggested: store a callback deadline (for example r.deadline + MAX_LIFETIME) and reject later deliveries, and/or let the requester close a resolved request so callbackDelivered can be set without a call. **Reproduction** State: ClausRequestInbox with dispatcher D; ClausRequestClient C with controller K. K calls C.submit(binding, capability, now+1 day, 'in') -> id. D calls inbox.resolve(id, true, keccak256('ev'), 'out'). Warp 5 years. Unrelated EOA 0x5155 calls inbox.deliverCallback(id, 'out'). Expected: rejected as stale, or restricted to dispatcher/requester. Actual: returns true and C.receipts(id).received == true. Reproduced in test/scratch/Leads.t.sol::testCallbackNoDeadline. ### 10. Info: ClausSignalStore binds to any executor-shaped contract; consumers must anchor on ClausSignalFactory.stores or executor(), not the store address `contracts/src/ClausSignalStore.sol:74` ``` if (approvalExecutor.code.length == 0 || target.code.length == 0 || feed == bytes32(0) || schema == bytes32(0)) revert InvalidProject(); ``` The constructor only requires that approvalExecutor and target have code and that the executor's projects()/pendingProjectOwners() views and the target's executor()/projectId() views are mutually consistent. Anyone can deploy a look-alike executor and evaluator satisfying those views and then deploy a ClausSignalStore carrying the real projectId, feedId and schemaHash, producing events and a latest() indistinguishable from a genuine store unless the reader checks store.executor() against the known executor or resolves the store through ClausSignalFactory.stores(projectId). Mirrors the earlier informational note on ClausNativeVault accepting any admissionPolicy. No on-chain fix strictly needed; document the anchoring rule for consumers and consider recording the factory address in the store. **Reproduction** Deploy FakeExecutor whose projects(bytes32) returns (attacker, fakeTarget, ..., generation 1, enabled true) and pendingProjectOwners returns 0; deploy FakeTarget exposing executor() == FakeExecutor, projectId() == realProjectId, version() == 1, evaluate(bytes). Call new ClausSignalStore(FakeExecutor, realProjectId, FakeTarget, realFeedId, realSchemaHash). Expected for a store trusted by address: revert. Actual: deployment succeeds; the attacker's signature registers a grant and publish stores sequence 1 under the real projectId/feedId. Reproduced in test/scratch/Leads.t.sol::testFakeExecutorStoreDeploys. ### 11. Info: Requester can cancel a pending request at any time, including ahead of the dispatcher's resolve, wasting the sponsored work `contracts/src/ClausRequestInbox.sol:72` ``` if (r.state != State.Pending) revert RequestClosed(); ``` resolve() (dispatcher) is bounded by the deadline and Pending state, while cancel() (requester) has no cutoff other than Pending. A requester can cancel in the same block as, or ahead of, the dispatcher's resolve, and the dispatcher's transaction reverts RequestClosed after the sponsored off-chain work was done. State stays consistent (Cancelled, no result recorded, no callback) and there are no fees or deposits, so the only cost is the operator's wasted compute and gas. Recorded for denial-of-service coverage as a design property of the sponsored inbox; if protection is wanted, a cancellation notice window or two-step cancel closes the race. **Reproduction** State: requester R calls request(binding, capability, now+1 day, 0, input) -> id (Pending). R calls cancel(id); dispatcher then calls resolve(id, true, evidenceHash, result). Expected from the dispatcher's view: result recorded. Actual: revert RequestClosed. Reproduced in test/scratch/Leads.t.sol::testRequesterCancelFrontRunsResolve. ### 12. Info: Vault admission policy only sees per-account state, so no policy can bound aggregate custody `contracts/src/ClausNativeVault.sol:57` ``` bytes memory callData = abi.encodeWithSignature("evaluate(bytes)", abi.encode(account, amount, nextPrincipal)); ``` ClausNativeVault passes only (account, amount, nextPrincipal) to the admission policy and accepts when nextPrincipal <= maximum. totalPrincipal is never part of the input and admissionPolicy is immutable, so no future Claus-approved policy module can enforce a vault-wide ceiling or rate-limit aggregate inflow; since any EOA can deposit, a per-account ceiling bounds nothing in aggregate. This matches the README (per-account ceiling only) and is a capacity note for the operator: if the pilot ever relies on the admission policy to bound custody exposure, a new vault with totalPrincipal in the policy input is needed. **Reproduction** State: ClausVaultAdmission configured (enabled true, maximum 2 ether). Alice deposits 2 ether (accepted); Alice deposits 1 wei more: DepositDenied. Bob deposits 2 ether: accepted; totalPrincipal == 4 ether and grows with each fresh address. Expected if the ceiling were meant to bound custody: denial once the vault total exceeds the maximum; actual: only the per-account check exists. Reproduced in test/scratch/Leads.t.sol::testVaultCeilingPerAccountOnly and exhibited by the existing testCeilingIsPerAccountAndCannotCreditAnotherDepositor. ### 13. Info: Oversized evaluate() input reverts with the misleading error OversizedConfiguration `contracts/src/ClausReadonlyProject.sol:37` ``` if (input.length > 8192) revert OversizedConfiguration(); ``` evaluate() rejects an input longer than 8192 bytes with OversizedConfiguration, the error _apply uses for an oversized stored configuration. Off-chain tooling mapping errors to the signal/vault error table attributes the failure to the project's configuration instead of the caller's input. Fix: add a distinct error such as OversizedInput. **Reproduction** Call ClausReadonlyProject.evaluate(new bytes(8193)) on any registered project whose configuration is within bounds. Expected: an input-specific error. Actual: revert OversizedConfiguration(). Reproduced in test/scratch/Leads.t.sol::testOversizedInputError. --- Judge's submission `f98cefb7ca4b5f2b0a02e383352195e71aa79283c28e43ab899d00fa24de3e76`, accepted on the IdentityMD network. Acceptance means the report met the job's checks; it is not a guarantee that the code has no other defects.
