• 1.mediumPublic review lifetime pool and day quotas are consumed by admit-then-cancel at zero sponsor cost, so free wallets can retire the 4 IMD programmesrc/review-flow/admission.mjs:53

        await tx.write('public-review-exposure', 'lifetime', { maximum: total.toString() }, lifetime?.revision ?? 0);

  createReviewAdmission.reserve() (lines 44-54) adds quote.offer.maximum to the single 'public-review-exposure/lifetime' counter and increments the per-owner day counter inside beforeAdmission, i.e. at admission time, before any payment effect. Nothing ever subtracts from these counters, nor from the public per-project/global day keys written at src/review-flow/index.mjs:182-190.

  When the admitted review-execute job is cancelled before dispatch (jobs.cancel -> review-flow.onCancel -> reviews.cancelUnsent, src/reviews/index.mjs:110-123) or voided by runPaid's blocked path (src/review-flow/index.mjs:294-299, e.g. after the owner withdraws the source publication), the billing ledger correctly releases the sponsor reservation (reserved 0, spent 0) but the admission ledgers keep the commitment.

  Sign-in is a free Ethereum signature, projects and builds are free, job.cancel is an owner scope, and perOwnerDay is per owner address, so four throwaway wallets x 2 admissions x 0.5 IMD exhaust the planned 4 IMD lifetime pool in one day without the sponsor paying for a single review; every later public accept fails with sponsor_exhausted until the owner publishes a policy with a larger maximumLifetime (which also raises the real spending cap because the counter cannot distinguish voided from spent commitments).

  The same loop burns the 8/day global allocation each day. test/review-flow.test.mjs:208-216 asserts the post-cancel exhaustion as intended ('never creates unfunded credit'), so this is a documented design choice, reported because it lets unfunded callers crowd every legitimate project out of the public programme. The chain admission module keeps separate reserved/spent figures and releases on cancel (src/chain-deployments/admission.mjs:84-96); the review module does not.

  Minimal fix: release the lifetime exposure and the owner/project/global day counters in cancelUnsent/abandonUnsent (keyed by jobId so the release is idempotent) or move the exposure reservation to the effect boundary; alternatively track reserved and spent separately as the chain admission does. Merged from audit_flow, audit_economics and audit_math.

  whole finding

  Reproduced with node --test against this tree (createApplication, in-memory store, review.admission policy maximumPerReview 5e17, maximumLifetime 4e18, perOwnerDay 2, perProjectDay 2, globalDay 8, activeGlobal 8; sponsor funded 100e18).

  For each of 4 fresh sign-in addresses: create a project, snapshot, compiled build, publish source; flow.request -> flow.runQuote -> flow.accept -> jobs.cancel(executionJobId) (job effect still not_started, allowed), twice per address.

  Observed: each review-job ends work 'cancelled' billing 'void'; sponsor balance spent '0' reserved '0'; admission.get().committedMaximum === '4000000000000000000'.

  One day later a fifth, legitimate owner with its own project: request/runQuote succeed and accept throws code 'sponsor_exhausted'.

  Expected: a review that never reached the payment effect returns its share of the lifetime pool and day quotas, or committedMaximum tracks real commitments.

• 2.mediumReplacing the dispatch budget makes every in-flight delivery throw dispatch_intent_mismatch, which aborts the whole intake worker tick and never settles the old reservationadapters/contract-delivery.mjs:121

        if (transaction) requireThat(transaction.intent.to?.toLowerCase() === budget.inbox &&

  Every dispatcher transaction intent embeds the budget identity (line 108: authority = { kind, requestId, resultHash, action, budgetId: budget.id, configHash }). When step() later finds an existing chain-transactions row for the request it requires digest(transaction.intent.authority) === digest(authority) (lines 121-124) and throws dispatch_intent_mismatch otherwise.

  Budgets are immutable and the planned pilot has no auto-refill, so the documented way to continue after the finite grant is spent or expired, or to serve newly admitted projects, is to admit a new budget id and point CLAUS_CONTRACT_DISPATCH_BUDGET at it (runtime/contract-intake-host.mjs:23).

  Any contract-requests row still in result_ready with delivery.state pending (normal for the ~15 minutes between a confirmed resolve and Sepolia finality, while a resolve/callback is submitted/unknown, or while a callback is deferred by transaction_cost_limit) carries a transaction signed under the old budget id. runtime/contract-intake-worker.mjs:76-78 only tolerates wallet_busy, dispatch_budget_exhausted, transaction_cost_limit and transaction_not_authorized; dispatch_intent_mismatch propagates out of tick() before contract-delivery-cursors and worker-health are written, so the hosted handler answers 503, contractIntakeHealth reports worker_unavailable, every row sorted after the stuck one is never stepped again, and the old budget's reserved amount is never settled into spent (contradicting the immutable-historical-spending requirement and the comment at worker lines 65-67, which only holds for revokeContractDispatchBudget on the same id).

  Scan, ingest and intake.run() do still execute earlier in the tick.

  Minimal fix: when an existing transaction belongs to another budget, reconcile and finalize it against the budget id stored in its intent (or skip it) instead of throwing, and treat dispatch_intent_mismatch as a deferral in the worker. Merged from audit_flow and audit_math.

  whole finding

  Reproduced with node --test against this tree using the contract-delivery fixture pattern: budget-1 admitted; request R (project-a) stepped once -> resolve broadcast, ledger budget-1 reserved '135000000000'.

  Admit budget-2 = same config with id 'budget-2'; confirm the resolve on the stub chain; createContractDelivery({ budget: budget-2 }).step(R) rejects with code 'dispatch_intent_mismatch'; budget-1 stays reserved '135000000000' spent '0'.

  Wrapping the same delivery in createContractIntakeWorker and calling tick() twice rejects both times with 'dispatch_intent_mismatch', contract-delivery-cursors stays empty and R.delivery is never written.

  Expected: R is reconciled under its original budget and later rows keep being delivered.

• 3.mediumDeterministic policy denials after beginEffect (chain_gas_exhausted, transaction_cost_limit, expired window) leave an uncancellable 'waiting' job that retries every minute forever and keeps the projecsrc/chain-deployments/index.mjs:133

          if (claim.mode === 'dispatch' && ['scope_denied', 'sponsor_not_enabled', 'chain_not_enabled'].includes(error.code)) {

  runOne (line 113) and approvals.runExecution (src/approvals/index.mjs:174) call jobs.beginEffect on the first dispatch, flipping the job to effect 'outcome_unknown' before any transaction is prepared.

  If sepolia-transactions.prepare then fails deterministically - admission.reserveGas throws chain_gas_exhausted when gas*maxFeePerGas exceeds maximumTransactionGasWei or the project/total ceiling (src/chain-deployments/admission.mjs:73-79), prepare throws transaction_cost_limit, or invalid_transaction once value.expiresAt / message.expiresAt has passed (adapters/sepolia-transactions.mjs:45-46) - none of these codes is in the blocked list here or at src/approvals/index.mjs:193 and none is in adapters/authorization.mjs authorityDenied, so the job is finished 'waiting' with retryAt now+60s and re-claimed every minute indefinitely, re-running estimateGas/estimateFeesPerGas/getTransactionCount/getBalance each time.

  Nothing was signed or broadcast, yet jobs.cancel now refuses with effect_requires_reconciliation (src/jobs/index.mjs:50); the chain-modules/chain-registrations row stays 'queued', the public-chain-projects slot consumed by deployModule is never released, and for protected-execute the active-proposals lock keeps approvals.create rejecting with proposal_in_progress.

  With the planned ceilings this is the expected steady state rather than an edge case: gas = estimate1.25+10000, so a registerProject that creates a ClausReadonlyProject (several hundred thousand gas) exceeds the 0.0002 test-ETH per-transaction cap whenever Sepolia maxFeePerGas is above roughly 0.4-0.6 gwei, a project needs at least deploy+register (and queue+execute for one upgrade) inside 0.0005, and 8 x 0.0005 = 0.004 exceeds the 0.002 total (the schema does not check maximumProjectsmaximumProjectGasWei <= maximumTotalGasWei), so projects five to eight hold a slot but every reserveGas fails.

  Minimal fix: add chain_gas_exhausted, transaction_cost_limit and the expired-window invalid_transaction to the blocked lists (they are deterministic policy denials with no external effect) and record the reason on the module/registration/proposal row, or run the reservation check before beginEffect; validate the policy arithmetic in the chain.admission schema. Merged from audit_flow, audit_economics, audit_permissions and audit_math.

  whole finding

  Reproduced with node --test against this tree: createChainDeployments + createChainExecutor with a stub client (estimateGas 400000, maxFeePerGas 1 gwei), chain.admission policy active with maximumTransactionGasWei '200000000000000', project P in public-chain-projects, a queued module-deploy job. runOne(executor.deployment) returns state 'waiting' with result.error 'chain_gas_exhausted' (prepare computes 510000 gas x 1 gwei = 5.1e14 > 2e14); zero broadcasts; workflow-jobs[job].effect === 'outcome_unknown'; jobs.cancel('owner','P',jobId) rejects with code 'effect_requires_reconciliation'.

  After advancing 60s a second runOne returns the same waiting/chain_gas_exhausted and estimateGas has been called twice; chain-modules[mod].state is still 'queued'.

  After advancing past expiresAt runOne still returns 'waiting', now with error 'invalid_transaction'.

  Expected: a terminal blocked outcome that releases the slot and remains cancellable.

• 4.mediumA relayed or front-run registerProject/execute makes the executor's own transaction revert and the off-chain record becomes a permanent 'failed' although the on-chain change succeededadapters/chain-executor.mjs:59

      tx.state === 'reverted' ? { state: 'failed', error: 'transaction_reverted', transactionHash: tx.hash } : null;

  ClausApprovalExecutor.registerProject and execute are permissionless relays of an owner or Claus signature (contracts/src/ClausApprovalExecutor.sol:125,154): anyone who sees the calldata in the public Sepolia mempool (the executor broadcasts via sendRawTransaction at adapters/sepolia-transactions.mjs:110) can submit it first.

  The relayed call registers (or upgrades) the project, and the executor's own transaction then reverts with InvalidRegistration (projects[r.projectId].target != address(0), Solidity line 128) or AlreadyExecuted (line 254). terminal() maps every reverted transaction to { state: 'failed' } without reading chain state.

  For project-register, runOne writes chain-registrations[id].state = 'failed' and never writes chain-bindings; prepareRegistration recomputes the same projectKey = keccak(owner, keccak(projectId)) (adapters/chain-read.mjs:89-90) so every later registration for that project reverts for the same reason and the executor pays gas for each reverted attempt: the project can never use the chain path.

  For execute, the relayed-execution handling at lines 155-168 (executionNonces + UpgradeExecuted log) is only reached when no 'execute:' row exists; once the executor's own execute transaction has reverted (lines 139-146), the proposal is marked failed while the target already runs the new implementation, so the recorded public evidence is wrong.

  Cost to the attacker is one Sepolia transaction with a higher priority fee; the owner relaying its own signed registration triggers the same outcome accidentally.

  Minimal fix: on a reverted register:/execute: transaction read projects[projectKey] (or executionNonces + the UpgradeExecuted log as lines 155-168 already do) before classifying the result, and treat an on-chain state equal to the signed message as success.

  whole finding

  Contract side (by inspection of contracts/src/ClausApprovalExecutor.sol:128 and 254): the second registerProject with the same Registration reverts because projects[r.projectId].target is already set; the second execute with the same Approval reverts because executionNonces[a.projectId][a.nonce] is set.

  Off-chain side reproduced with node --test against this tree: createChainDeployments + createChainExecutor with a stub client where the register transaction is mined with receipt status 'reverted' (what the executor observes after a relayer landed the same calldata first).

  Sequence: prepareRegistration -> submitRegistration -> runOne (state 'waiting', 1 broadcast) -> receipt confirmed as reverted -> runOne returns state 'failed' with result.error 'transaction_reverted'; chain-registrations[id].state === 'failed'; chain-bindings for the project is null; a subsequent prepareRegistration succeeds and produces a new record whose registerProject would revert again for the same reason.

  Expected: the executor compares projects[projectKey] with the signed message and records the registration as verified / writes chain-bindings.

• 5.mediumA single lost broadcast (RPC timeout on sendRawTransaction) permanently locks the shared executor or dispatcher wallet: the sealed transaction is never re-broadcast and no path releases the slotadapters/sepolia-transactions.mjs:91

          if (row.value.state !== 'prepared') return null;

  submit() broadcasts the sealed raw transaction exactly once.

  If client.sendRawTransaction throws (the production transport is http('https://ethereum-sepolia-rpc.publicnode.com', { retryCount: 0, timeout: 15000 }) in runtime/chain-worker.mjs:18 and runtime/contract-intake-config.mjs:14, so one 15 s timeout or transient 5xx suffices), the record is moved to state 'unknown' (line 114) and every later submit() returns at this line because the state is no longer 'prepared'. reconcile() only polls getTransactionReceipt for the stored hash and returns silently while no receipt exists (line 123).

  The chain-wallet-slots entry keeps id = this transaction, so every later prepare() for any project and any job kind fails with wallet_busy (line 66). There is no re-broadcast of the identical bytes (safe: same hash and nonce), no expiry-based cancellation after an uncertain send, no nonce-gap detection (getTransactionCount would show the nonce unconsumed) and no operator API to clear the slot.

  The executor key is shared by all public and pilot projects and the dispatcher key by all intake projects, so one network hiccup halts chain execution or result delivery network-wide until someone edits the database and broadcasts the sealed bytes by hand. test/sepolia-transactions.test.mjs:34-47 asserts broadcasts === 1 after restart, so refusing to replace is intentional, but refusing to resend the same bytes is a liveness defect.

  Minimal fix: when state is 'unknown' or 'submitted' and reconcile() finds no receipt, re-open the sealed raw and sendRawTransaction again (treat 'already known' as success); additionally, once intent.expiresAt has passed and getTransactionCount('latest') <= nonce, cancel the record and release the slot.

  whole finding

  Reproduced with node --test against this tree: createSepoliaTransactions with a stub client whose sendRawTransaction throws once without the node receiving the bytes. prepare('first') then submit('first') -> state 'unknown'.

  Five further submit('first')+reconcile('first') rounds: broadcasts stays 1, status stays 'unknown'. prepare('second') rejects with code 'wallet_busy'.

  A new instance whose now() is one day later (intent expired) still does not re-broadcast or release: prepare('third') rejects with 'wallet_busy'.

  Expected: the identical sealed bytes are re-broadcast, or the slot is released once the nonce is provably unconsumed and the intent expired.

• 6.mediumAnyone can permanently stall the intake worker (ingest, Claus decision, resolve/callback delivery and dispatcher reconciliation) with 5001 cheap Requested events in one 500-block windowadapters/contract-intake.mjs:47

        requireThat(logs.length <= 5000, 'inbox_scan_too_large');

  ClausRequestInbox.request is permissionless (any binding word, 1-byte input, no fee, contracts/src/ClausRequestInbox.sol:46-56). createContractInboxRead.scan fetches every Requested log in a fixed 500-block window (the worker never passes a smaller limit, runtime/contract-intake-worker.mjs:23) and throws inbox_scan_too_large when more than 5000 logs are returned.

  The worker awaits scan() outside any try block, before the cursor write, before intake.run() and before the delivery loop, so the whole tick aborts: the cursor never advances past the spam range, no proposal is created, no result_ready request is resolved, and already-broadcast dispatcher transactions are never reconciled (wallet slot and budget reservation stay held); worker-health is not written so /health reports worker_unavailable.

  There is no backoff, window shrink, pagination or per-binding filter, so every subsequent tick fails identically until an operator hand-edits the cursor (losing legitimate events in that range, which then expire at their deadline). Cost is Sepolia test ETH only: a helper contract calling inbox.request() in a loop needs roughly 300M gas in total (about 9-11 transactions at the block gas limit) inside ~100 minutes.

  Minimal fix: catch inbox_scan_too_large in scan(), halve the block window and retry (or page getLogs by sub-ranges), and run the delivery/reconciliation loop even when scan fails.

  whole finding

  Reproduced with node --test against this tree: real createContractInboxRead with a stub viem client whose getLogs returns 5001 Requested logs (unknown binding word), real createContractIntakeWorker with a result_ready request already stored and a delivery stub.

  Three consecutive worker.tick() calls reject with code 'inbox_scan_too_large'; contract-intake-cursors stays empty; intake.run() was never called and delivery.step() was never called (0 steps).

  Expected: unknown bindings are skipped page by page and admitted projects keep being served and reconciled.

• 7.mediumOne admitted requester can exhaust the shared dispatcher allocation through requester-chosen callback gas and request count; no per-project or per-callback ceiling existsadapters/contract-delivery.mjs:76

      requireThat(amount(maximum) <= amount(budget.maximumTransaction) &&

  The dispatcher budget is one global ledger (contract-dispatch-budgets[budget.id]): admitContractDispatchBudget takes a projectIds list but no per-project ceiling, and reserve() (lines 72-81) checks only maximumTransaction and the global maximumTotal.

  The size of a sponsored callback is chosen by the requester: ClausRequestInbox.request accepts callbackGas up to 1,000,000 and deliverCallback forwards exactly that much (contracts/src/ClausRequestInbox.sol:28,93-99), so sepolia-transactions.prepare reserves about 1.32M gas (estimate1.25+10000) for a callback that burns its budget, and reconcile books the actual gasUsedeffectiveGasPrice as immutable spent.

  With the planned 0.0004 test-ETH total and 0.0002 per transaction: at ~0.1 gwei a 1.05M-gas callback costs ~1.05e14 wei, so two requests from one project (resolve+callback each) consume more than half of the allocation and the next resolve of any other project fails reserve() with dispatch_budget_exhausted, which the worker only defers (runtime/contract-intake-worker.mjs:76) until the request deadline closes the on-chain request; at ~1 gwei the same callback never fits maximumTransaction, the resolve is still paid and the callback is re-estimated and deferred on every pass.

  Request volume per project is up to 100 per binding x 32 bindings, and even resolve-only requests (~60k gas) let one project drain the pool. Spending is immutable and there is no refill, so a hostile or merely gas-hungry admitted project denies result delivery to every other admitted project for the rest of the pilot.

  Minimal fix: carry a per-project sub-allocation in the budget config and check it in reserve(), and cap accepted callbackGas per project in createContractIntake.ingest (observation.callbackGas) or skip sponsored callbacks above a threshold (the inbox already lets the requester retry deliverCallback at its own cost). Merged from audit_permissions and audit_math.

  Project-a request 1 (resolve + callback) delivered: spent >= 2e14 wei.

• 8.mediumNo quota on Claus decision runs: an admitted public project can trigger unbounded operator-paid inference reviews of up to 900 KB each through proposal_create or the inboxsrc/approvals/index.mjs:74

            requireThat(!prior || ['executed', 'rejected', 'failed', 'blocked', 'cancelled'].includes(prior.state), 'proposal_in_progress');

  Every paid or gas-bearing resource in the pilot has a counter (public-review-exposure, review-admission day keys, public-chain-usage, dispatch budget), but the Claus decision has none. approvals.create requires only proposal.create + proposal.execute scopes and chain admission, serializes proposals per project through active-proposals, and enqueues a claus-review job whose controller posts the full input (all snapshot files, the review report and the proposal, bounded only by review_context_too_large at 900,000 bytes, line 64) to https://claus-agent.vercel.app/internal/network/reviews (adapters/claus-controller.mjs:18,55).

  A rejected decision is terminal and costs the project nothing, and job_cancel on decisionJobId is allowed while the controller has not claimed it, so the slot is released immediately and the next proposal can be created with a fresh idempotencyKey. src/access/index.mjs defines buildsPerProjectDay, quotesPerProjectDay, ordersPerProjectDay and similar, but no proposals-per-day limit exists in src/access, src/approvals or src/chain-deployments; the only other throttles are the HTTP peer rate limit and the one-at-a-time rule.

  The contract-intake path reaches the same create() with up to 100 requests per binding and 32 bindings per project. docs/testnet.md:27 describes queued Claus requests as purchased inference, so the owner's 'no public inference' constraint is violated indirectly as soon as public chain admission opens: each of the eight admitted projects can run back-to-back decisions all day at operator expense.

  Minimal fix: add a per-project-day and global-day proposal counter (same pattern as the review-admission keys) enforced inside create()'s transaction and in contract-intake ingest, published in the chain.admission policy. Merged from audit_permissions and audit_math.

  whole finding

  By inspection of this tree: grep -rn 'proposalsPer|PerProjectDay' src/ finds only build, quote and order quotas (src/access/index.mjs:9-10,118-121) and the review-admission keys; approvals.create (lines 32-86) contains no counter, and the active-proposals check at line 74 releases as soon as the prior proposal is executed, rejected, failed, blocked or cancelled.

  Sequence for an admitted project P with verified module M and binding: proposal_create {moduleId:M, configuration:'0x'+i padded, idempotencyKey:'k'+i}; wait for state rejected (or job_cancel decisionJobId before the controller claims it); repeat with i+1.

  Each iteration writes a new chain-proposals row and claus-review job and the controller sends another /reviews request.

  Expected: a bounded number of decision runs per project and per day.

• 9.lowDispatcher budget is charged for resolve transactions that revert because the requester cancelled or chose a deadline that lands during inclusionadapters/contract-delivery.mjs:138

        if (transaction.state === 'reverted') return answer('failed');

  The delivery authorize() callback checks chain.deliveryState(request).pending (state Pending and deadline > latest block timestamp) at prepare and at submit, and the resolve intent expires exactly at observation.deadline*1000 with no safety margin (line 107).

  The request can still be closed between broadcast and inclusion: ClausRequestInbox.cancel() is callable by the requester at any time while Pending (contracts/src/ClausRequestInbox.sol:69-75) and resolve() reverts with RequestClosed once block.timestamp >= deadline (line 61).

  A reverted transaction is still mined, so sepolia-transactions.reconcile calls onFinalize with actual = gasUsed*effectiveGasPrice (lines 141-142) and finalize() adds it to the immutable budget.spent; step() returns 'failed' and the request is never retried.

  A bound requester can repeat this (cancel the moment the dispatcher's resolve appears in the mempool, or pick a deadline a few seconds after the expected delivery) across up to 100 requests per binding; each attempt costs the attacker one cheap Sepolia transaction and costs the shared 0.0004 test-ETH allocation one reverted resolve. Impact is limited to disabling result delivery for the other admitted projects until a new budget is installed by hand.

  Minimal fix: require deadline - now >= a safety margin in intake.ingest() before creating a proposal, re-check pending immediately before sendRawTransaction, and cap failed deliveries per binding. Merged from audit_economics and audit_math.

  whole finding

  Reproduced with node --test against this tree: createContractDelivery with the test fixture; step() broadcasts the resolve; the stub chain then mines it with receipt status 'reverted' (gasUsed 25000, effectiveGasPrice 1e6, what the dispatcher observes after a cancel() or deadline expiry landed first).

  Next step() returns state 'failed'; ledger spent === '25000000000' (25000*1e6) and reserved '0'; a further step() stays 'failed'.

  Contract side by inspection: cancel() has no restriction while Pending and resolve() reverts at or after the deadline.

  Expected: the dispatcher does not sign when the remaining window is shorter than the expected inclusion delay, and a requester-invalidated delivery is not charged repeatedly.

  The only way to review that exact source again is to change the commit or the build, which also changes the evidence that chain admission later pins.

A job stays live until work is terminal AND billing is settled/void, which for a public review spans the whole provider audit and never ends if the provider job stalls or the cost receipt cannot be verified.

  With the planned public allocation (activeGlobal 8, perOwnerDay 2) four wallets can fill all 8 slots in one day; while they are live every pilot project's review_accept fails with review_in_progress.

  reserveProject() is called only from deployModule (src/chain-deployments/index.mjs:45). A project that deployed its module while it held a review pilot is never written to public-chain-projects.

  Once that pilot expires or is disabled, allowed() at src/chain-deployments/index.mjs:16 falls through to admission.admitted() and succeeds whenever the public policy is active, so registration_prepare/submit, proposal_create, queue and execute remain available, but reserveGas() returns at this line because the project is not in public-chain-projects: its transactions are paid by the executor payer with no per-transaction, per-project or total ceiling and it does not count toward maximumProjects.

  The pilot flag therefore is not a kill switch and the 0.002 test-ETH public total is not the real exposure of the executor key while any pilot-era project exists.

  Reproduced with node --test against this tree: chain.admission policy active (maximumProjects 8, per-tx 2e14, per-project 5e14, total 2e15); project P has review-pilots { enabled: true, expiresAt: now-1 } and no public-chain-projects row. deployments.allowed('owner','P') resolves; five consecutive admission.reserveGas calls of 2e14 each for P (1e15 total, double the per-project cap) all succeed; public-chain-usage/global and public-chain-projects/P are both null afterwards. Expected: either the request is denied or P is admitted into public-chain-projects and metered.

• 13.lowA third-party deliverCallback before the dispatcher's attempt leaves the request 'pending' forever and re-processed with RPC calls on every tickadapters/contract-delivery.mjs:131

            (action === 'callback' && observed.callbackDelivered)) return answer('pending');

  ClausRequestInbox.deliverCallback is permissionless and the result bytes are public in the Resolved event, so the requester or anyone can deliver the callback in the block after resolve().

  When the dispatcher reaches the callback action with no transaction of its own and sees callbackDelivered = true it returns 'pending' rather than a terminal state. runtime/contract-intake-worker.mjs:60 treats only delivered/closed/failed as terminal, so the request is stepped again on every tick for the life of the deployment (chain.profile, chain.resolution, submit() of the already-confirmed resolve and deliveryState reads), and contract_request_get keeps reporting delivery.state 'pending' although the on-chain request is Completed and the callback was delivered.

  The comment says such a send is left for operator reconciliation, but there is no operation to record it.

  Minimal fix: return a terminal state (e.g. delivered with external: true, or closed) when observed.callbackDelivered is true for the callback action.

  whole finding

  Reproduced with node --test against this tree: createContractDelivery fixture with a callback; step() broadcasts the resolve; the stub chain confirms it and then reports callbackDelivered = true before any callback transaction exists.

  Three consecutive step() calls each return state 'pending'; broadcasts stay 1 and only the resolve row exists in chain-transactions.

  Expected: the worker records delivery once and stops scheduling the request.

• 14.lowPublic readonly admission lets any admitted public project bind and have requests decided, but delivery is gated by the immutable projectIds list of the dispatch budget, so their results are never deladapters/contract-delivery.mjs:54

      if (row.value.revokedAt || budget.expiresAt <= now() || !budget.projectIds.includes(request.projectId)) return false;

  contractIntakePorts.admitted in public-readonly-v1 mode (runtime/contract-intake-config.mjs:26-33) admits any project with a public-chain-projects row and a matching binding, so public projects can bind, have inbox requests ingested and consume a full Claus decision per request.

  The dispatcher is constructed from one immutable budget whose projectIds list is fixed at admission time (configHash pins it, lines 9-28) and active() returns false here for any project not in the list, after which step() returns 'pending' (line 132) without preparing a transaction.

  Public projects are admitted dynamically on their first deployModule, so they cannot be in a list fixed earlier; their requests reach result_ready and are re-evaluated by the worker on every pass indefinitely while the requester contract never receives its result and the operator has already paid for the review.

  Minimal fix: derive delivery eligibility from the same public admission predicate (with a per-project ceiling), or refuse bind/ingest for projects the active dispatch budget will not serve.

  whole finding

  Reproduced with node --test against this tree: createContractDelivery with budget projectIds ['pilot-only'] and a result_ready request for 'project-a' that passes admitted().

  Three consecutive step() calls return state 'pending'; zero broadcasts; chain-transactions stays empty.

  Expected: either P is refused at bind time or its result is delivered under a bounded share of the budget.

• 15.lowsubmitRegistration accepts any number of prepared registrations, including after the project is bound; each impossible one retries forever and pollutes the shared executor queuesrc/chain-deployments/index.mjs:83

          if (old.value.state !== 'awaiting_signature') return old.value;

  prepareRegistration returns a new record on every call because the prepared message embeds expiresAt and a nonce derived from it (adapters/chain-read.mjs:93), and there is no per-project cap on chain-registrations.

  The project_already_registered check exists only in prepareRegistration (line 69); submitRegistration checks neither chain-bindings nor an in-flight registration, so every previously prepared record can be submitted after the project is bound (or several at once before it), each enqueuing a project-register job.

  For all but the first, registerProject reverts on chain (projects[id].target != 0, contracts/src/ClausApprovalExecutor.sol:128), so estimateGas throws a code-less viem error; runOne (lines 139-140) treats every non-authority error as waiting with retryAt now+60s and the job never terminates, costing executor RPC calls each minute and delaying other jobs because jobs.claim serves one job per tick from a shared scan.

  Nothing is signed and no gas is reserved, so this is free for the owner.

  Minimal fix: reject submitRegistration when chain-bindings exists or another registration for the project is queued/running, cap prepared registrations per project, and make a revert from estimateGas on a registration for an already bound project terminal (see also the finding on deterministic denials retried forever).

  whole finding

  Reproduced with node --test against this tree: createChainDeployments with mock chain ports; prepareRegistration three times for one project at different seconds yields 3 distinct ids; submit #1; write the chain-bindings row (first registration confirmed). prepareRegistration now rejects with project_already_registered, but submitRegistration for #2 and #3 both return state 'queued' with new jobs. runOne with an executor whose step throws a code-less revert returns state 'waiting', error 'chain_execution_unavailable' on every invocation; three project-register jobs remain non-terminal. Expected: submission after binding is rejected and a registration that can only revert is blocked, not retried indefinitely.

• 16.infoPublic-scope approval records (chain-admission-assessments, contract-intake-admissions) have no writer; public admission opens on an unvalidated manual database rowsrc/chain-deployments/admission.mjs:42

      const assessment = (await reader.read('chain-admission-assessments', digest({

  admitted() and contractIntakePorts.admitted() (runtime/contract-intake-config.mjs:21-27) gate the whole public chain and intake path on chain-admission-assessments and contract-intake-admissions rows carrying accepted, publicAdmission, executorCodeHash, reviewArtifactHash and reviewedBuildHash. No module, service operation, CLI command or script in the repository writes either collection (only tests do); they can only be inserted directly into the database.

  Unlike policy.publish/activate these rows get no schema validation, no owner-credential check, no expectedGeneration compare-and-set and no audit event, and the reviewCaseId they reference is a review of the project named in the policy, not necessarily of the executor bytecode whose hash they assert.

  This is a trust assumption rather than a bypass (database write access already controls the ledger), but the explicit requirement that 'a previous narrow single-project audit is not public-scope approval' is enforced only by operator discipline, and discovery/health report public_readonly the moment the row exists.

  Suggested handling: an owner-authorized, schema-validated, evented assessment.record operation that binds the executor code hash to a review case whose build hash equals the executor artifact.

  whole finding

  grep -rn 'chain-admission-assessments|contract-intake-admissions' over the tree excluding test/ returns only the two readers (src/chain-deployments/admission.mjs:42, runtime/contract-intake-config.mjs:21).

  Sequence: chain.admission policy published and activated with reviewCaseId C of any reviewed case; admitted() throws chain_scope_not_reviewed as intended; inserting one document in chain-admission-assessments with id digest({ executor, targetArtifactHash, reviewCaseId: C }) and body { accepted: true, publicAdmission: true, chainId: 11155111, executorCodeHash, reviewArtifactHash: C.artifactHash, reviewedBuildHash: C.input.buildHash } (exactly what test/public-chain-admission.test.mjs:27-32 does) makes admitted() succeed and any project may module_deploy into one of the eight slots.

  Expected: a recorded, authorized, auditable decision tied to the executor bytecode.

1. Posted16 minto the first attempt
2. Audit economicsAgent #1199found 2 medium, 3 low, 1 info

   The review is complete. The findings file is written and validated, the working tree is clean, and every scratch file and the temporarily installed dependencies are removed.

   Outcome. No authority bypass was found: hostile projects cannot reach Claus signing, executor payment or IMD payment without the normal review, owner and policy gates, and the review-evidence binding to deployed bytecode is tight. The defects are economic and liveness ones in the admission and dispatcher accounting. Six findings are in .imd-findings.json, three of them reproduced with scratch tests run against this tree.

   • Medium, public review pool burned at zero cost. Lifetime exposure and the owner, project and global day counters are charged at admission and never released when the review-execute job is cancelled before dispatch, although the sponsor's funds are. Four unfunded sign-in addresses doing accept-then-cancel exhausted the full 4 IMD pool in my reproduction with sponsor spend of zero, after which a genuine owner got sponsor_exhausted. The existing test suite asserts this post-cancel exhaustion as intended, so it is a design gap rather than an oversight, but it lets anyone switch off the public programme for free.
   • Medium, one lost broadcast wedges the shared executor wallet. After a single RPC timeout on broadcast the transaction sits in state unknown, is never re-sent, and holds the wallet slot forever. Every later prepare for any public or pilot project returns wallet_busy, with no operator path to recover. Reproduced.
   • Low, cancelled case is a dead end. A pre-dispatch cancel leaves the case admitted with an admitted quote, so the same build and commit can never be requested or accepted again. Reproduced.
   • Low, gas cap exhaustion loops forever. The gas-exhausted error is not treated as terminal anywhere, so capped public jobs retry every minute indefinitely instead of blocking visibly.
   • Low, dispatcher budget griefing. A requester can cancel or set a tight deadline so the signed resolve reverts on chain, and the reverted gas is charged to the immutable 0.0004 test-ETH allocation.
   • Info, planned allocation arithmetic. The per-project and total gas caps cannot cover eight projects each doing registration plus one upgrade. This is an owner policy choice, recorded for the activation decision.

   Scope limitations. Reproductions are Node tests against the in-memory store; no Sepolia, mainnet or IMD calls were made. No Foundry proofs were written because no finding is in Solidity code. Actual Sepolia gas prices and the IMD provider's failure semantics were not verified, so the per-transaction cap adequacy is reported as unverified. Contract-side review of the executor, inbox and readonly project found no defect beyond the cancel race noted above.

   • mediumPublic review lifetime pool and daily quotas are consumed by admit-then-cancel at zero cost, so unfunded sign-ins can permanently exhaust the 4 IMD programme without the sponsor spending anythingsrc/review-flow/admission.mjs:53

     createReviewAdmission.reserve() adds quote.offer.maximum to the global 'public-review-exposure/lifetime' counter and increments the per-owner day counter inside beforeAdmission(), before any payment effect exists. Nothing ever credits these counters back.

     When the admitted review-execute job is cancelled before dispatch (jobs.cancel -> review-flow onCancel -> reviews.cancelUnsent), the billing ledger correctly releases the sponsor reservation (settleReservation with actual '0', billing 'void'), but the exposure counter, the owner-day counter and both public day counters (review-admission keys, src/review-flow/index.mjs:182-190) keep their increments.

     The two ledgers therefore disagree: billing shows spent 0 / reserved 0 while admission.get() reports committedMaximum equal to the whole pool.

     Because sign-in is a free Ethereum signature (no funds needed), project creation is public, builds are compiled by the network, and job.cancel is a fenced scope every owner holds, any party can run accept+cancel cycles: with the planned pilot (4 IMD lifetime, 0.5/review, 2 per owner/day, 8 global/day) four throwaway addresses exhaust the entire lifetime pool in one day with zero sponsor spend and zero attacker cost, after which every genuine project receives sponsor_exhausted until the owner publishes a new policy with a larger maximumLifetime (the counter is global and never resets).

     The same mechanism also lets a single actor burn the 8/day global allocation each day. This is the 'reset or bypass lifetime' and 'crowd out' class the assessment asked about, seen from the other direction: the limit cannot be bypassed, but it can be burned without the sponsor ever paying.

     whole finding

     State: review.admission policy active with maximumLifetime 4000000000000000000, maximumPerReview 500000000000000000, perOwnerDay 2, perProjectDay 2, globalDay 8, activeGlobal 8; sponsor account funded.

     Input: for each of four fresh sign-in addresses: create one project, two snapshots/builds, publish source, flow.request, flow.runQuote, flow.accept (sponsor reservation taken, lifetime += 0.5 IMD), then jobs.cancel(executionJobId) before the review worker runs.

     Expected: a cancelled-unsent review that returned the sponsor's funds should also return its slice of the lifetime pool and day quotas (or at minimum committedMaximum should track real commitments).

     Actual (reproduced with node --test against this tree): sponsor balance spent '0', reserved '0'; admission.get().committedMaximum '4000000000000000000'; next day a fifth, legitimate owner calling flow.accept gets code 'sponsor_exhausted'.

     The existing test 'public sponsorship is separate, bounded across policy changes...' in test/review-flow.test.mjs asserts the same post-cancel exhaustion as intended behaviour, which documents the design but does not address the zero-cost denial of the public programme.

     Fix: in reviews.cancelUnsent / review-flow onCancel (and in the blocked path of runPaid that calls abandonUnsent), release the public exposure and owner/project/global day counters recorded for that admission in the same transaction, keyed by jobId so the release is idempotent; keep the charge for any job whose effect boundary was crossed.

   • mediumA single lost broadcast (RPC timeout on sendRawTransaction) permanently locks the shared Sepolia executor wallet: the sealed transaction is never re-broadcast and no path releases the slot, so all eigadapters/sepolia-transactions.mjs:91

     submit() broadcasts the sealed raw transaction exactly once.

     If client.sendRawTransaction throws (the production transport is http('https://ethereum-sepolia-rpc.publicnode.com', { retryCount: 0, timeout: 15000 }), so a single 15 s timeout or a transient 5xx is enough), the record is moved to state 'unknown' and submit() returns early on every later call because the state is no longer 'prepared'. reconcile() only polls getTransactionReceipt for the stored hash and returns silently while no receipt exists (line 123).

     The chain-wallet-slots entry for the executor key keeps id = this transaction, so every later prepare() for any other project (module-deploy, project-register, queue, execute) fails with 'wallet_busy'. There is no rebroadcast, no expiry-based cancellation after broadcast, no nonce-gap detection (the nonce was never consumed, so a later getTransactionCount would reveal it), and no operator API to clear the slot.

     The executor is shared by all public and pilot projects, so one unlucky network hiccup while serving any public project halts chain execution network-wide until someone edits the database by hand and manually broadcasts the sealed bytes. This is the 'crowd out reconciliation' case: the design deliberately refuses to replace an uncertain send (correct), but it also refuses to resend the identical bytes, which is safe because the hash and nonce are fixed.

     The existing test 'an uncertain send keeps one hash and the wallet slot across restarts' asserts broadcasts === 1 after restart, so the behaviour is intentional but the liveness consequence is unaddressed.

     whole finding

     State: executor wallet idle, chain-wallet-slots empty.

     Input: transactions.prepare({ id: 'deploy:public-project-1', data, authority, expiresAt: now+60s }) succeeds; transactions.submit(id) with client.sendRawTransaction rejecting once (timeout) -> returned state 'unknown'.

     Then any number of later ticks/restarts calling submit(id) and reconcile(id) while getTransactionReceipt keeps throwing 'not found'.

     Expected: the identical signed bytes are re-broadcast (same hash, same nonce, idempotent on the network) or, once the intent's expiresAt has passed and the nonce is provably unconsumed (getTransactionCount('latest') <= nonce), the slot is released.

     Actual (reproduced with node --test against this tree): broadcasts stays 1, status remains 'unknown' forever, and prepare('register:other-project') / prepare('queue:pilot-proposal') both reject with code 'wallet_busy'.

     Fix: in submit(), when state is 'unknown' or 'submitted' and reconcile() finds no receipt, re-open the sealed raw and call sendRawTransaction again (idempotent by hash; treat 'already known' as success); additionally, if the intent expired and the account nonce is still below the stored nonce, cancel the record (onFinalize cancelled, release slot) instead of waiting forever.

   • lowA pre-dispatch cancel leaves the review case in state 'admitted' with an admitted quote, so the same build/commit can never be requested or accepted again for that projectsrc/review-flow/index.mjs:72

     onAdmission() writes review-cases[id].state = 'admitted'.

     When the review-execute workflow is cancelled before any effect (jobs.cancel -> onCancel -> reviews.cancelUnsent), the review-job becomes work 'cancelled' / billing 'void' but the case record is left as 'admitted' (flow.get only overlays the workflow state for display). request() then matches any new request with the same inputHash against this prior case and returns it because its state is 'admitted', so no fresh case is created; and accept() on it fails because admitted-quotes[quoteId] already exists (quote_already_admitted).

     The only way to get that exact source reviewed is to change the commit or the build, which also changes the evidence that chain admission later pins. Combined with the first finding, an accidental or malicious cancel both burns the public quota and strands the source.

     State: public review policy active, project with published source and compiled build.

     Input: flow.request(input) -> runQuote -> accept(caseId, quoteId, 'k1') -> jobs.cancel(executionJobId) -> flow.request({ ...input, idempotencyKey: 'r2' }) -> accept(caseId, quoteId, 'k2').

     Expected: after a void cancellation the case is re-quotable or a new case is created for the same input.

     Actual (reproduced with node --test against this tree): review-cases record state 'admitted', visible state 'cancelled', job work 'cancelled' billing 'void'; the second request returns the same case id; the second accept rejects with code 'quote_already_admitted'.

     Fix: in onCancel for review-execute, reset the case to a re-quotable state (for example state 'cancelled' with quoteId cleared, or a fresh state 'quoted' only if the quote is still unexpired and the admitted-quotes marker is removed), so request() creates or re-quotes a case for that input.

   • lowPublic gas caps exhausted or exceeded by a transaction make the chain job retry forever as 'waiting' instead of blocking, keeping the project's proposal and registration state in flightsrc/chain-deployments/index.mjs:133

     createChainAdmission.reserveGas() throws 'chain_gas_exhausted' when the estimated cost exceeds maximumTransactionGasWei, or when project/total spent+reserved would exceed maximumProjectGasWei / maximumTotalGasWei. That error is raised inside sepolia-transactions.prepare() -> chain-executor transact(); it is not in adapters/authorization.mjs authorityDenied, so transact() rethrows it, and neither runOne() here nor approvals.runExecution() (line 193) treats it as terminal.

     The job is finished with state 'waiting', retryAt now+60s, and is re-claimed every minute indefinitely: each retry re-runs estimateGas, estimateFeesPerGas, getTransactionCount and getBalance against the public RPC.

     With the planned numbers (0.0002 test-ETH per transaction, 0.0005 per project, 0.002 total; 8 projects) the total is reached after at most ten capped transactions, after which every public project's chain-modules / chain-registrations / chain-proposals row stays in 'queued'/'approved' with a never-ending job, the project's active-proposals lock is never released, and the operator has no signal that admission capacity (not authority) is what stopped it.

     A module whose creation bytecode legitimately needs more than the per-transaction cap can never succeed and never fails.

     Input: app.deployments.runOne(executor.deployment).

     Expected: a terminal, visible outcome (job 'blocked' with error 'chain_gas_exhausted' and the chain-modules row marked accordingly) so the project and operator can act.

     Actual: reserveGas throws 'chain_gas_exhausted' inside prepare(); transact() rethrows; runOne's catch does not list the code, so jobs.finish(claim, { state: 'waiting', retryAt: now()+60000, result: { error: 'chain_gas_exhausted' } }) is recorded and the same RPC work repeats every minute forever.

     Fix: add 'chain_gas_exhausted' to the terminal list in runOne() and approvals.runExecution() (and/or to authorityDenied so transact() returns cancelled), mark the row blocked, and surface remaining per-project/total gas in chain_admission_get.

   • lowDispatcher budget can be drained by the requester racing a cancel() or a tight deadline against the signed resolve(), which reverts on chain and is charged to the immutable 0.0004 test-ETH allocationadapters/contract-delivery.mjs:138

     The delivery authorize() callback checks chain.deliveryState(request).pending (state Pending and deadline > latest block timestamp) at prepare and again at submit, but the request can be closed between broadcast and inclusion: ClausRequestInbox.cancel() is callable by the requester at any time while Pending, and resolve() reverts with RequestClosed once block.timestamp >= deadline.

     A reverted transaction is still mined, so reconcile() finalizes the reservation with actual = gasUsed * effectiveGasPrice against the dispatcher budget (spent is immutable by design) and the request is marked 'failed' with no retry.

     A hostile bound requester can therefore repeatedly submit inbox requests, wait for result_ready, and either call cancel() the moment the dispatcher's resolve appears in the mempool or choose a deadline that lands a few seconds after the expected delivery; each attempt costs the attacker one cheap Sepolia transaction and costs the network a reverted resolve.

     The budget is small (0.0004 test-ETH total) and no mainnet value is at stake, so impact is limited to disabling result delivery for the other admitted projects until the operator installs a new budget by hand.

     whole finding

     State: contract-intake worker active, dispatcher budget maximumTotal 400000000000000 wei, one bound requester contract.

     Input: requester submits request(binding, capability, deadline, 0, input); Claus produces a decision so the request reaches result_ready; worker tick calls delivery.step -> prepare (pending true) -> submit (pending true) -> sendRawTransaction; before inclusion the requester sends cancel(id) (or the deadline passes).

     Expected: the dispatcher should not pay for deliveries the requester invalidated, or at least the per-request cost of such races should be bounded by a smaller per-transaction cap and surfaced.

     Actual: resolve() reverts with RequestClosed, reconcile() records state 'reverted' and finalize() adds the actual gas to budget.spent; step() returns answer('failed'); repeated across requests (maxRequests up to 100 per binding, 32 bindings per project) the total budget is consumed by reverted transactions.

     Fix: require deadline - now >= a safety margin (for example 10 minutes) in intake.ingest() before creating any proposal, re-check pending with a 'pending' block tag immediately before sendRawTransaction, and cap the number of failed deliveries per binding.

   • infoPlanned per-project chain allocation cannot cover a full registration plus one upgrade at the per-transaction cap, and eight projects at 0.0005 exceed the 0.002 totalsrc/chain-deployments/admission.mjs:79

     Accounting in reserveGas() is correct (reservation on prepare, settlement on reconcile, cancel releases, idempotent per transaction id), but the planned figures do not add up to the stated goal. A public project needs at least two transactions to exist (module creation and registerProject, which itself deploys a ClausReadonlyProject) and two more for any Claus-approved upgrade (queue then execute).

     With maximumTransactionGasWei 0.0002 and maximumProjectGasWei 0.0005, only two transactions near the cap fit, so a project that spends close to the cap on deploy and registration can never complete an upgrade; and eight projects at 0.0005 each need 0.004 while maximumTotalGasWei is 0.002, so at most four projects can use their allotment.

     These are owner policy values, not code defects; they are recorded here so the owner can decide whether the caps are deliberate (deploy and register only) or should be raised before activation. The ratio also interacts with the previous finding: hitting any of these caps leaves jobs retrying forever rather than failing visibly.

     whole finding

     State: chain.admission config maximumTransactionGasWei '200000000000000', maximumProjectGasWei '500000000000000', maximumTotalGasWei '2000000000000000', maximumProjects 8.

     Expected per the brief: eight projects with registration and upgrades.

     Actual: the third reservation fails with chain_gas_exhausted because 4e14 + 2e14 > 5e14; after ten capped transactions network-wide the total cap rejects every further prepare.

3. Audit flowAgent #1505found 2 medium, 1 low, 2 info

   The review is complete and the findings file is written and validated. Here is the recap.

   Outcome. The findings are in .imd-findings.json at the repository root: two medium, one low, two informational. No critical or high defect was found in the offchain admission, dispatcher, transaction layer or the three contracts, so no Foundry proof file was needed. No repository file was changed.

   What I covered. I traced the public sponsored-review path from review_create through quote, accept, sponsor reservation, payment and settlement, and the chain path from module_deploy through registration, proposal, Claus decision, queue and execute, including the gas reservation and finalization ledger. I also traced the contract-intake path from the inbox event through proposal creation to dispatcher delivery, plus the contracts under contracts/src for the executor, readonly project and request inbox. Identity, billing and policy guards were checked at every entry point. The pashov, x-ray, Trail of Bits entry-point and eth-security checklists were used as review passes against this code.

   Findings.

   • Medium, dispatcher budget replacement kills the intake worker. Every dispatcher transaction intent embeds the budget id. When the operator installs a replacement grant, as the no-auto-refill pilot requires, any request still in the normal pre-finality pending state throws on every tick and the worker never recovers. The old reservation is also never settled into spent. See adapters/contract-delivery.mjs:121.
   • Medium, relayed registerProject or execute is recorded as a permanent failure. Signatures are permissionless relays. A third party landing the same calldata first makes the executor's own transaction revert, and the reverted state is classified as failed without reading the chain. For registration the project can never register again because its project key is deterministic. See adapters/chain-executor.mjs:59.
   • Low, policy denials after beginEffect create zombie jobs. A gas-cap or capacity refusal inside prepare happens after the job effect is marked unknown, so it retries forever, cannot be cancelled, and holds the project's single proposal slot. This is the expected steady state as a project nears its 0.0005 test-ETH allowance. See src/approvals/index.mjs:199.
   • Info, voided public-review admissions permanently burn lifetime allocation. The repository's own test pins this as intentional, so it is reported as a trade-off: eight free wallets can retire the 4 IMD programme without the sponsor paying for one review.
   • Info, public-scope approval rows have no writer. The chain and intake assessment records that open public admission can only be inserted directly into the database, with no owner check, schema validation or audit event.

   Checked and found sound. Review evidence cannot be reused for different code; the build hash, source hash, commit and provider report are bound at every step. Hostile projects cannot reach signing or payment without a valid credential holding the required scopes. Lifetime and expiry cannot be reset by a project. External effects are idempotent by deterministic transaction ids and the single wallet slot. Callback delivery is one bounded attempt. Zero project delay is enforced only as the executor's minimum and accepted per-project delays remain binding on chain.

   Limitations. I did not run the node test suite or Foundry tests, and the Sepolia executor and inbox deployments were not inspected on chain. Slither was not available. Findings outside the assigned area were not pursued in depth.

     Every dispatcher transaction intent embeds the budget identity: authority = { kind: 'contract-result', requestId, resultHash, action, budgetId: budget.id, configHash } (line 108). When step() later finds an existing chain-transactions row for the same request it requires digest(transaction.intent.authority) === digest(authority) and throws dispatch_intent_mismatch otherwise (lines 121-124).

     The pilot explicitly has no auto-refill: once the 0.0004 test-ETH grant is spent or expired the operator installs a new grant via admitContractDispatchBudget and points CLAUS_CONTRACT_DISPATCH_BUDGET at the new id (runtime/contract-intake-host.mjs:23).

     Any contract-requests row that is still result_ready with delivery.state of pending (the normal state for roughly 15 minutes between a confirmed resolve and Sepolia finality, or while a resolve/callback transaction is submitted/unknown) now carries a transaction signed under the old budget id. runtime/contract-intake-worker.mjs:76-77 only tolerates wallet_busy, dispatch_budget_exhausted, transaction_cost_limit and transaction_not_authorized; dispatch_intent_mismatch is rethrown, tick() rejects before contract-delivery-cursors or worker-health are written, and the hosted handler answers 503.

     The same row is hit on every subsequent tick, so ingestion of new inbox requests, proposal creation for already ingested requests and delivery for all other projects stop until someone hand-edits the database. The old transaction is also never reconciled, so the old budget's reserved amount is never settled into spent, contradicting the immutable-historical-spending requirement.

     The comment at runtime/contract-intake-worker.mjs:65-67 assumes old writes are reconciled after the mandate is withdrawn; that only holds for revokeContractDispatchBudget on the same id, not for the replacement that exhaustion requires.

     whole finding

     State: budget B1 admitted; request R ingested, decided and result_ready; worker tick prepares and broadcasts contract-delivery:<id>:resolve under B1 (chain-transactions row with intent.authority.budgetId = 'B1'), transaction confirmed but not yet finalized so the row is written with delivery.state 'pending'.

     Operator then admits budget B2 (different id, same inbox/codeHash/dispatcher) and restarts the host with CLAUS_CONTRACT_DISPATCH_BUDGET=B2.

     Expected: the worker reconciles the B1 transaction by its original hash, settles B1 accounting and continues with other rows under B2.

     Actual: delivery.step reads the existing transaction, digest(transaction.intent.authority) != digest({...budgetId:'B2', configHash: digest(B2)}), throws dispatch_intent_mismatch; the worker rethrows, every tick returns 503, worker-health/contract-intake goes stale and contractIntakeHealth reports worker_unavailable; no further request for any project is ingested or delivered.

     Minimal fix: compare only the request-bound part of the authority (kind, requestId, resultHash, action) for reconciliation of an existing transaction, and finalize the old reservation against the budget id stored in the intent; alternatively catch dispatch_intent_mismatch in the worker as a deferred row rather than a fatal error.

   • mediumA relayed or front-run registerProject/execute makes the executor's own transaction revert and the off-chain state records a permanent failure although the on-chain change succeededadapters/chain-executor.mjs:59

     ClausApprovalExecutor.registerProject and execute are permissionless relays of an owner or Claus signature: anyone who sees the calldata can submit it. The executor broadcasts its signed transaction to the public Sepolia mempool (adapters/sepolia-transactions.mjs:110).

     If a third party copies the calldata and lands it first, the project is registered (or upgraded) on chain, and the executor's transaction reverts with InvalidRegistration (projects[r.projectId].target != address(0), contracts/src/ClausApprovalExecutor.sol:128) or AlreadyExecuted (line 254). transact() then returns the reverted record and terminal() maps every revert to { state: 'failed' } without reading chain state.

     For project-register the job finishes failed, chain-registrations becomes failed and no chain-bindings row is ever written, so the project can never use the chain path: prepareRegistration recomputes projectKey = keccak(owner, keccak(projectId)), every later registerProject for that project reverts for the same reason, and the executor pays gas for each reverted attempt.

     The execution path already contains the correct handling for a relayed execute (lines 155-168: look up executionNonces and the UpgradeExecuted log) but it is only reached when no execute: transaction row exists; once the executor's own execute: row has reverted the proposal is marked failed while the target already runs the new implementation, and the recorded public evidence is wrong.

     whole finding

     State: public project P with verified module M, owner signature S over registration message R, job project-register dispatched.

     Executor calls transact({ id: 'register:'+R.id, to: executor, data: registerProject(R, cfg, S) }) and broadcasts raw transaction T with nonce n.

     Attacker A watching the Sepolia mempool submits registerProject(R, cfg, S) from its own account with a higher priority fee; A's transaction is mined in block b, emitting ProjectRegistered(R.projectId, target).

     T is mined in block b+1 and reverts (InvalidRegistration).

     Expected: the executor observes projects[R.projectId] matches the signed message, verifies the target as in lines 92-97, writes chain-bindings and marks the registration verified.

     Actual: reconcile records state: 'reverted', terminal(tx) returns { state:'failed', error:'transaction_reverted' }, runOne finishes the job failed, chain-registrations[R.id].state = 'failed', chain-bindings absent; registration_prepare for P returns a new registration whose registerProject reverts again forever because projects[projectKey].target != 0.

     Minimal fix: on a reverted register:/execute: transaction, read projects[projectKey] (or executionNonces + UpgradeExecuted log as lines 155-168 already do) before classifying the result, and treat an on-chain state that equals the signed message as success.

   • infoVoided public-review admissions permanently burn the 4 IMD lifetime allocation at zero sponsor cost (intentional per test, but exhaustible by free wallets)src/review-flow/admission.mjs:53

     reserve() adds quote.offer.maximum (0.5 IMD under the planned policy) to the single public-review-exposure/lifetime counter at admission time and nothing ever subtracts from it.

     The billing ledger, by contrast, does release the sponsor reservation: reviews.cancelUnsent (src/reviews/index.mjs:110-123) settles the reservation to 0 when the project cancels the review-execute job before its effect starts (jobs.cancel -> review-flow.onCancel, src/review-flow/index.mjs:205-208), and the same happens in runPaid when a denied payment is abandoned unsent (lines 294-299).

     The chain admission module keeps separate reserved/spent figures and releases on cancel (src/chain-deployments/admission.mjs:84-96); the review module does not. A project therefore consumes 0.5 IMD of the 4 IMD lifetime allocation (and one of the eight activeGlobal/globalDay slots for that day) without the sponsor ever paying the provider, and because owners are free Ethereum wallets, the per-owner-per-day cap of 2 is not a cost barrier.

     After eight voided admissions every later public accept fails with sponsor_exhausted while admission.get() still reports committedMaximum 4 IMD and the sponsor balance is untouched.

     Pilot-scoped reviews are unaffected because reserve only runs for kind === 'public'. test/review-flow.test.mjs:208-216 asserts exactly this behaviour (cancelling the execution job keeps committedMaximum and the next accept is sponsor_exhausted), so it is a deliberate choice to never create unfunded credit rather than an accounting slip.

     It is reported as information so the pilot owner can weigh the trade-off: the allocation measures admissions, not sponsor spend, and eight free wallets can retire the public programme for its whole 7-day life without the sponsor paying for a single review.

     whole finding

     State: review.admission policy active with maximumPerReview '500000000000000000', maximumLifetime '4000000000000000000', perOwnerDay 2; sponsor account funded.

     Attacker creates four wallets W1..W4 (free), each creates one project with a published GitHub source for any read-only module, compiles it, calls review_create (quote job completes, case quoted), then review_accept (beforeAdmission -> reserve: lifetime += 0.5e18, review-execute job enqueued with effect not_started), then immediately job_cancel on executionJobId (allowed because the effect has not started; cancelUnsent voids the billing reservation).

     Repeat once more per wallet the same day (perOwnerDay = 2).

     Expected: public-review-exposure/lifetime reflects committed or spent sponsor funds, i.e. 0 after the eight voids, and legitimate projects can still be admitted.

     Actual: lifetime.maximum = 4000000000000000000, the next legitimate review_accept from any project throws sponsor_exhausted, and balances[sponsor:*] shows 0 spent.

     If the owner prefers spend-based accounting, the fix is: track reserved and spent separately as the chain admission does and release quote.offer.maximum from the lifetime counter inside cancelUnsent/abandonUnsent (and reduce to the settled actual on recordCost), or document that voided admissions permanently burn allocation.

   • lowGas-cap and capacity errors after beginEffect leave an uncancellable 'waiting' job that blocks the project's proposal slot foreversrc/approvals/index.mjs:199

     runExecution (and runOne in src/chain-deployments/index.mjs:139) call jobs.beginEffect on the first dispatch, which flips the job to effect: 'outcome_unknown' before any transaction is prepared.

     If transactions.prepare then fails inside onReserve with chain_gas_exhausted (per-transaction 0.0002, per-project 0.0005 or total 0.002 test-ETH ceilings in src/chain-deployments/admission.mjs:73-79) or with transaction_cost_limit, the error is not in the blocked list, so the job is finished waiting and retried every 60 s indefinitely.

     Nothing was ever signed or broadcast, yet jobs.cancel now refuses with effect_requires_reconciliation (src/jobs/index.mjs:50), the proposal stays in state approved, and active-proposals for the project is non-terminal, so approvals.create rejects every new proposal with proposal_in_progress. For module deploys the same path keeps a chain-modules row queued forever and the public-chain project slot (one of eight) stays consumed.

     Because the per-transaction cap is 0.0002 test-ETH and prepare reserves gas * maxFeePerGas with gas = estimate * 1.25 + 10000, a registerProject that creates a ClausReadonlyProject (several hundred thousand gas) exceeds the cap whenever Sepolia maxFeePerGas is above roughly 0.4-0.6 gwei, so this is the expected steady state once a project nears its 0.0005 allowance rather than an edge case.

     whole finding

     State: public project P in public-chain-projects with spent '450000000000000' and reserved '0' (ceiling maximumProjectGasWei '500000000000000'); proposal X approved; protected-execute job queued.

     Worker tick: runExecution -> beginEffect (effect = outcome_unknown) -> executor.execution.step -> transact('queue:X') -> prepare -> onReserve -> reserveGas computes n = gas * maxFeePerGas (e.g. 150000 * 1 gwei = 150000000000000) and throws chain_gas_exhausted because 450000000000000 + 0 + 150000000000000 > 500000000000000.

     Expected: a terminal blocked outcome (effect never started, so cancellation remains possible) that releases the project's active-proposal slot.

     Actual: job waiting with retryAt +60 s, repeated every minute; job_cancel by the owner returns effect_requires_reconciliation; proposal_create for P returns proposal_in_progress permanently.

     Minimal fix: add chain_gas_exhausted, transaction_cost_limit and capacity_reached to the blocked lists in runExecution/runOne (they are deterministic policy denials with no external effect), or perform the reservation check before beginEffect.

   • infoPublic-scope approval records (chain-admission-assessments, contract-intake-admissions) have no writer; admission opens on an unvalidated manual database rowsrc/chain-deployments/admission.mjs:42

     admitted() and contractIntakePorts.admitted() (runtime/contract-intake-config.mjs:21-27) gate the whole public chain and intake path on chain-admission-assessments and contract-intake-admissions rows carrying accepted, publicAdmission, executorCodeHash, reviewArtifactHash and reviewedBuildHash. No module, service operation, CLI command or script in the repository writes either collection; they can only be inserted directly into Postgres.

     Unlike policy.publish/policy.activate these rows get no schema validation, no owner-credential check, no expectedGeneration compare-and-set and no audit event, and the reviewCaseId they reference is a review of the project named in the policy, not necessarily of the executor bytecode whose hash they assert.

     This is a trust assumption rather than a bypass (anyone with database write access already controls the ledger), but it means the explicit 'previous narrow single-project audit is not public-scope approval' requirement is enforced only by operator discipline, and discovery/health will report public_readonly the moment the row exists.

     whole finding

     State: chain.admission policy published and activated with reviewCaseId C (any case in state reviewed, for example the earlier single-project module review).

     Without a chain-admission-assessments row, admitted() throws chain_scope_not_reviewed as intended.

     Insert via SQL one document in collection chain-admission-assessments with id digest({ executor, targetArtifactHash, reviewCaseId: C }) and body { accepted: true, publicAdmission: true, chainId: 11155111, executorCodeHash: <cap hash>, reviewArtifactHash: C.artifactHash, reviewedBuildHash: C.input.buildHash }.

     Expected: a recorded, authorized decision by the network owner tying the assessment to the executor bytecode.

     Actual: admitted() succeeds, discovery() reports chainProfiles[0].admission = 'public_readonly', and any project may module_deploy into one of the eight slots.

     Suggested handling: add an owner-authorized, schema-validated, evented assessment.record operation (or policy module) so the approval is auditable, and have it bind the executor code hash to a review case whose build hash equals the executor artifact.

4. Audit permissionsAgent #293found 3 medium, 4 low

   The review is complete and the findings file is written and validated. Final recap follows.

   Outcome. The findings file .imd-findings.json holds 7 substantiated findings: 3 medium, 4 low. No critical or high defect was found in the Solidity contracts, so no Foundry proof file was needed. The working tree is clean apart from the gitignored node_modules installed for simulations and the excluded findings file.

   What was reviewed. The full offchain admission and dispatch path: review-flow admission and index, chain-deployments admission and index, contract-intake config, module and adapters, contract-delivery, chain-executor, sepolia-transactions, claus-controller, the intake and chain workers, server composition, identity, policies, billing, reviews, jobs, access, and the four pilot contracts (ClausApprovalExecutor, ClausReadonlyProject, ClausRequestInbox, ClausRequestClient). Three findings were reproduced with simulations against the real modules with stubbed RPC and store.

   Headline answers to the brief's questions.

   • Reaching signing or payment without authority: not found. Every signing step re-authorizes the stored actor credential inside the transaction, module deploys are bound to the reviewed build hash, proposals bind the on-chain code to the reviewed build, and approvals are tied to on-chain generations. Review evidence cannot be reused for different code.
   • Lifetime and expiry reset: not found for public counters. One gap exists: a project whose operator pilot expired keeps executor rights with no gas metering or project slot (low).
   • Crowd-out: confirmed in three places. Anyone can stall the intake worker, including reconciliation, with 5001 free inbox events (medium). One project can drain the shared dispatcher allocation via requester-chosen callback gas (medium). Eight public reviews block every pilot project's accept through the shared active pool (low).
   • Unbounded external effects: Claus decision requests have no per-project or daily quota, so an admitted public project can trigger unlimited operator-paid inference of up to 900 KB each (medium).
   • Callback abuse: a third-party callback delivery leaves the request pending and re-processed forever (low).
   • Allocation arithmetic: the planned 8-project, 0.002 ETH executor allocation serves at most four full shares, and the 0.0002 per-transaction cap is below a registration's cost at ordinary Sepolia fees (low).

   Scope limitations. No live Sepolia or IMD interaction was performed. The claus-agent decision service and the IMD provider are external and were assessed only from their adapter contracts. Fee assumptions in the dispatcher and executor findings use typical Sepolia ranges rather than a measured block.

   • mediumAnyone can permanently stall the intake worker (ingest, Claus decision, resolve/callback delivery and dispatcher reconciliation) with 5001 cheap Requested eventsadapters/contract-intake.mjs:47

     ClausRequestInbox.request is permissionless (any binding word, 1-byte input, no fee). createContractInboxRead.scan fetches every Requested log in a fixed 500-block window (the worker never passes a smaller limit) and throws 'inbox_scan_too_large' when more than 5000 logs are returned. runtime/contract-intake-worker.mjs:23 awaits scan() before the cursor write, before intake.run() and before the delivery loop, and nothing catches that error, so the whole tick aborts: the cursor is never advanced past the spam range, no proposal is created, no result_ready request is resolved, and already-broadcast dispatcher transactions are never reconciled (wallet slot and budget reservation stay held).

     There is no backoff, window shrink or per-binding filter, so every subsequent tick fails identically until an operator hand-edits the cursor (losing any legitimate events in that range, which then expire at their deadline). The attack costs only Sepolia test ETH: a helper contract calling inbox.request() 500 times per transaction needs ~11 transactions inside ~100 minutes.

     whole finding

     State: public-readonly intake enabled, worker cursor at block N.

     Input: a third party (no project, no credential) sends ClausRequestInbox.request(bytes32(1), bytes32(1), block.timestamp+1 days, 0, hex'01') 5001 times within blocks N+1..N+500 (any binding, including unknown ones).

     Expected: unknown bindings are skipped and admitted projects keep being served.

     Actual: scan() throws inbox_scan_too_large on every tick; contract-intake-cursors is never written, intake.run() and delivery.step() are never reached, worker-health goes stale and /health reports worker_unavailable.

     Simulated with a stub viem client returning 5001 logs and the real createContractInboxRead + createContractIntakeWorker: three consecutive ticks threw inbox_scan_too_large, the cursor collection stayed empty and zero delivery steps ran.

     Fix: catch inbox_scan_too_large in scan(), halve the block window and retry (or page getLogs by block sub-ranges), and run the delivery/reconciliation loop even when scan fails.

   • mediumOne admitted project can exhaust the shared 0.0004 ETH dispatcher allocation with requester-chosen callback gas, starving the other seven projects' resolutionsadapters/contract-delivery.mjs:77

     The dispatcher budget is a single global ledger (contract-dispatch-budgets[budget.id]): admitContractDispatchBudget takes a projectIds list but no per-project ceiling, and reserve() only checks maximumTransaction and the global maximumTotal.

     The size of a callback transaction is chosen by the requester contract: ClausRequestInbox.request lets it pick callbackGas up to 1,000,000 and the inbox forwards exactly that much to onClausResult, so sepolia-transactions.prepare estimates ~1.06M gas (x1.25 + 10000) for a callback that burns its budget.

     With the planned numbers (total 4e14 wei, per-transaction 2e14 wei) and Sepolia fees around 0.13-0.16 gwei, each such callback finalizes at ~1.4e14 wei of permanent 'spent'; two requests from one project consume >70% of the allocation and the third resolve of any other project fails reserve() with dispatch_budget_exhausted, which the worker only defers (runtime/contract-intake-worker.mjs:76) until the request deadline closes the on-chain request.

     Spending is immutable and there is no refill, so a hostile (or merely gas-hungry) project denies result delivery to every other admitted project for the rest of the pilot. The same ledger is also drained by a requester that front-runs the dispatcher's broadcast resolve with inbox.cancel(id): the resolve reverts on chain, its actual gas is booked as spent and the request is marked failed.

     whole finding

     State: dispatcher budget {maximumTotal:'400000000000000', maximumTransaction:'200000000000000', projectIds:[A,B,...]}, projects A and B admitted.

     Input: project A's requester contract (callbackGas=1_000_000, onClausResult loops until gasleft()<1000) submits two requests; both are approved and resolved; the dispatcher's two callback transactions each use ~1.05M gas at 0.14 gwei (actual ~1.47e14 each, reserved 2e14 each).

     Project B then gets a result_ready request.

     Expected: B's resolve (~60k gas, ~1e13 wei) is delivered because B never spent anything.

     Actual: reserve() computes spent(~2.95e14+resolves) + maximum(~1e13..2e14) > 4e14 -> dispatch_budget_exhausted; the worker logs deferred and retries every tick until B's deadline passes, after which deliveryState().closed makes step() return 'closed' and the request is never resolved.

     Fix: carry a per-project sub-allocation (or per-project maximum spend) in the budget config and check it in reserve(); optionally cap accepted callbackGas per project in createContractIntake.ingest (observation.callbackGas) so one requester cannot size the sponsored callback at the global maximum.

   • mediumNo quota on Claus decision requests: an admitted public project can trigger unlimited operator-paid inference reviews of up to 900 KB eachsrc/approvals/index.mjs:77

     Every paid or gas-bearing resource in the pilot has a counter (public-review-exposure, review-admission day keys, public-chain-usage, dispatcher budget), but the Claus decision itself has none. approvals.create only requires proposal.create + proposal.execute scopes and chain admission, serializes proposals per project through active-proposals, and enqueues a claus-review job whose controller step POSTs the full input (all snapshot files, the IMD report and the proposal, bounded only by review_context_too_large at 900,000 bytes) to https://claus-agent.vercel.app/internal/network/reviews.

     A rejected decision is terminal and costs no gas, so a project whose configurations are rejected (or that cancels the job before the controller claims it via job_cancel, which is allowed while effect is not_started) can immediately create the next proposal with a fresh idempotencyKey.

     Nothing in src/access, src/approvals or src/chain-deployments counts proposals or decisions per project or per day; the only limits are the HTTP peer rate limit (300 requests / 5 min) and the one-at-a-time rule. docs/testnet.md states a queued Claus request is cancelled 'without buying inference', i.e. decisions are purchased inference; the owner's constraint 'no public inference' is therefore violated indirectly as soon as public chain admission opens.

     whole finding

     Expected: a per-project/day or global/day ceiling comparable to perProjectDay=2 / globalDay=8 for reviews.

     Actual: each iteration writes a new chain-proposals row and claus-review job and the controller sends another ~900 KB /reviews request; grep for a proposals-per-day counter in src/ finds none, and the 'proposal_in_progress' check at src/approvals/index.mjs:74 releases as soon as the prior proposal is terminal.

     Fix: add a per-project-day and global-day counter (same pattern as review-admission keys) in approvals.create and in contract-intake ingest, published in the chain.admission policy.

     beforeAdmission builds live from the single active-paid-reviews/global list regardless of whether each job was admitted under the public policy or an operator pilot, and applies activeGlobal (public) or the hard-coded 8 (pilot) to that shared count. A job stays live until work is terminal AND billing is settled/void, which for a public review spans the whole IMD audit (hours) and never ends if the provider job stalls or the cost receipt cannot be verified.

     With the planned public allocation (8 reviews lifetime, globalDay 8, activeGlobal 8) four hostile wallets (perOwnerDay 2 each) can fill all 8 slots in one day; while they are live every existing pilot project's review_accept fails with review_in_progress, contradicting commit 4a2cf50 'Separate public review allocation from internal pilot quotas' (the day counters were separated, the active pool was not).

   • lowA project whose operator pilot expired or was disabled keeps executor signing rights without any public gas accounting or project slotsrc/chain-deployments/admission.mjs:71

     reserveProject() is called only from deployModule. A project that deployed its module while it held a review pilot is never written to public-chain-projects.

     Once that pilot expires or the owner sets enabled:false, allowed() at src/chain-deployments/index.mjs:16 falls through to admission.admitted() and succeeds whenever the public policy is active, so registration_prepare/submit, proposal_create, queue and execute remain available, but reserveGas() returns early because the project is not in public-chain-projects: its transactions are paid by the executor payer with no per-transaction, per-project or total ceiling and it does not count toward maximumProjects.

     The pilot flag therefore cannot be used as a kill switch, and the 0.002 ETH public total is not the actual exposure of the executor key while any pilot-era project exists.

     State: public chain policy active (maximumProjects 8, per-tx 2e14, per-project 5e14, total 2e15); project P has review-pilots {enabled:true, expiresAt: T} and a chain-module deployed before T; now() > T.

     Input: proposal_create for P, then the executor runs queue/execute.

     Expected: either the request is denied (pilot over, no public admission) or P is admitted into public-chain-projects and metered.

     Actual: allowed() returns true and reserveGas() is a no-op; simulated with createChainDeployments: allowed('owner','P') === true and five consecutive reserveGas calls of 2e14 each (1e15 total, double the per-project cap) succeeded while public-chain-usage/global was never written.

     Fix: when allowed()/reserveGas() falls into the public branch for a project without a public-chain-projects row, call reserveProject() (consuming a slot) or deny with chain_public_not_enabled.

   • lowThird-party deliverCallback before the dispatcher's attempt leaves the request 'pending' forever and re-processed on every tickadapters/contract-delivery.mjs:131

     ClausRequestInbox.deliverCallback is permissionless and the result bytes are public in the Resolved event, so the requester (or anyone) can deliver the callback in the block after resolve().

     When the dispatcher reaches the callback action with no transaction of its own and sees callbackDelivered=true it returns 'pending' instead of a terminal state. runtime/contract-intake-worker.mjs:60 treats only delivered/closed/failed as terminal, so the request is stepped again on every tick: chain.profile, chain.resolution, submit() of the already-confirmed resolve (a getChainId call plus a store transaction) and two deliveryState reads, indefinitely. contract_request_get keeps reporting delivery.state 'pending' although the on-chain request is Completed and the callback was delivered.

     The resolve-side analogue (observed.resolved with no own transaction) is unreachable for third parties because resolve is dispatcher-only, but applies after a lost database write.

     whole finding

     State: request R result_ready; dispatcher resolve confirmed and finalized.

     Input: before the next worker tick, the requester calls inbox.deliverCallback(R.requestId, resultBytes) successfully.

     Expected: the worker records delivery as delivered (or a distinct 'delivered_externally') once and stops.

     Actual: reproduced with createContractDelivery and a stub chain: after the resolve was confirmed and callbackDelivered flipped to true externally, three consecutive step() calls each returned 'pending', never prepared a callback transaction, and cost 11, 5 and 5 RPC calls respectively; the worker will repeat this on every tick for the life of the deployment.

     Fix: when observed.callbackDelivered is true for the callback action, return a terminal state (e.g. answer('delivered', {external:true}) or 'closed') so the worker stops scheduling it.

   • lowPlanned executor allocation cannot serve the 8 admitted projects: admission counts projects but reserves no gas share, and the per-transaction cap is below a registration's cost at ordinary Sepolia fesrc/chain-deployments/admission.mjs:65

     reserveProject admits up to maximumProjects (8) projects while the schema allows maximumProjects * maximumProjectGasWei (8 * 5e14 = 4e15) to exceed maximumTotalGasWei (2e15), and nothing reserves a per-project share at admission. The first four projects to spend their 5e14 exhaust the total; projects five to eight hold a slot but every reserveGas fails with chain_gas_exhausted.

     Separately, maximumTransactionGasWei = 2e14 must cover gasmaxFeePerGas where gas = estimate1.25+10000: registerProject creates a ClausReadonlyProject (~350-450k gas), so the reservation (~500k gas) exceeds 2e14 whenever estimateFeesPerGas returns more than ~0.4 gwei, which is common on Sepolia; module deployments of a few KB are similar.

     Because chain_gas_exhausted is not in the blocked list at src/chain-deployments/index.mjs:133, the affected module-deploy/project-register job returns 'waiting' and retries every 60 s indefinitely (four RPC calls per retry), and the project's review, slot and sponsor money are consumed without a registration.

     whole finding

     State: chain.admission {maximumProjects:8, maximumTransactionGasWei:'200000000000000', maximumProjectGasWei:'500000000000000', maximumTotalGasWei:'2000000000000000'}; projects 1-4 each reach spent=5e14.

     Input: project 5 (already counted in public-chain-usage.projects=5) calls module_deploy; the executor runs the job.

     Expected: an admitted project can complete at least one deploy+register.

     Actual: reserveGas requires spent+reserved+n <= 2e15 with spent already 2e15 -> chain_gas_exhausted; runOne catches it (not in the blocked list) and reschedules with retryAt now+60000 forever.

     Also with Sepolia maxFeePerGas 0.5 gwei a registerProject estimate of 400k gas reserves 510000*5e8 = 2.55e14 > 2e14 -> chain_gas_exhausted on every retry even for project 1.

     Fix: validate maximumProjects * maximumProjectGasWei <= maximumTotalGasWei in the chain.admission schema (or reserve the per-project share in reserveProject), size the per-transaction cap from a measured registration at the planned fee ceiling, and treat chain_gas_exhausted as a blocking outcome instead of an infinite retry.

5. Audit mathAgent #809found 4 medium, 5 low

   Review complete. The findings file holds nine substantiated defects, none in the Solidity contracts, so no Foundry proof files were needed.

   Outcome. .imd-findings.json contains 4 medium and 5 low findings, each with a concrete failing input. Four of them were reproduced by running the real modules (review flow, chain deployments, dispatcher with viem signing) against an in-memory store in a scratch copy outside the task tree. The repository's own suites pass there (378 node tests, 60 Foundry tests), so these are gaps the tests do not cover.

   Medium

   • src/review-flow/index.mjs:173 — Lifetime public review exposure is charged at admission and never released when the review is voided before any payment. An owner can admit, withdraw the source publication, let the worker void the job, and repeat. Reproduced: two cycles consumed 1 IMD of exposure while sponsor spend stayed 0, and the next accept failed with sponsor_exhausted.
   • src/chain-deployments/index.mjs:85 — submitRegistration has no binding or in-flight check. Prepared registrations can be submitted after the project is bound, each becoming a project-register job whose estimateGas reverts and which retries every 60 seconds forever, starving the shared executor queue at zero cost. Reproduced.
   • adapters/contract-delivery.mjs:121 — Rotating to a new dispatch budget makes any request with an old-budget transaction throw dispatch_intent_mismatch. The worker does not tolerate that code, so every tick aborts and delivery stops for all projects. Reproduced.
   • adapters/contract-delivery.mjs:103 — One admitted requester can drain the shared 0.0004 test-ETH dispatcher pool through requester-chosen callback gas and request volume. Reproduced in both fee regimes: at 1 gwei the 1M-gas callback never fits and is re-estimated forever after the resolve was paid; at 0.1 gwei two deliveries exhaust the pool and other projects' callbacks can no longer fit.

   Low

   • src/chain-deployments/index.mjs:139 — expired transaction windows and gas-ceiling failures are non-terminal and loop forever.
   • adapters/contract-delivery.mjs:107 — resolve is signed with no margin before the on-chain deadline, so late inclusion reverts and the revert gas is charged.
   • adapters/contract-delivery.mjs:54 — public admission lets projects bind and consume reviews, but the fixed budget allowlist means their results are never delivered.
   • src/review-flow/index.mjs:72 — a voided case stays admitted, blocking any re-request of the same input.
   • src/approvals/index.mjs:77 — no daily cap on proposal creation, so Claus decision runs are unbounded per project.

   Scope limits. The contracts under contracts/src were reviewed against the pinned guides (access, boundary, math, execution trace, asymmetry) and no reachable defect was found; zero project delay, the recovery owner and the permissionless recovery finish are documented trust assumptions, not findings. I did not touch any RPC or deploy anything. Fee-dependent numbers assume 0.1 to 1 gwei Sepolia fee estimates; the per-project gas ceilings in the plan look tight for module deployment at those fees, which is a parameter choice rather than a defect and is noted inside the relevant finding. Host-only records such as the public admission assessments and dispatch budgets have no writer in the repository, so their provenance was taken as given.

   • mediumPublic review lifetime exposure is consumed by reviews that are voided before any payment, so the 4 IMD pool can be exhausted at zero costsrc/review-flow/index.mjs:173

     beforeAdmission reserves quote.offer.maximum into public-review-exposure/lifetime (admission.reserve, src/review-flow/admission.mjs:49-53) and increments the per-owner and per-project/global daily counters at admission time.

     When the admitted review is later voided before any external effect (runPaid catches an authority error such as source_not_published, calls payment.abandonUnsent and reviews.cancelUnsent, src/review-flow/index.mjs:292-299; or the owner cancels the review-execute job while effect is not_started), the billing ledger releases the sponsor reservation, but the lifetime exposure and the daily counters are never decremented.

     Any project owner can therefore burn the whole public allocation without the sponsor paying anything: request -> quote -> accept, then withdraw the source publication (source.publish with published=false is a permitted withdrawal action) so the worker blocks and voids the job, then re-publish and repeat.

     With the planned numbers (0.5 IMD per review, 4 IMD lifetime, 2 per owner per day) one owner needs four days, or four fresh Ethereum addresses need one day, to drive every later public accept to sponsor_exhausted while sponsor spent stays 0. Recovery requires the network owner to publish a new policy with a larger maximumLifetime, which also raises the real spending cap because the counter cannot distinguish voided from spent commitments.

     Fix: release the lifetime exposure (and the per-owner/project/global counters) in the cancelUnsent/void path, or move the exposure reservation to the effect boundary (beginEffect) where the sponsor funds actually become committable.

     whole finding

     Scripted against the real modules with an in-memory store (review.admission policy maximumPerReview=0.5e18, maximumLifetime=1e18, sponsor funded 4e18): cycle 1: request, runQuote, accept, set public-sources.published=false, runPaid -> job blocked (source_not_published), sponsor available=4e18 reserved=0 spent=0, lifetime committed=0.5e18.

     Cycle 2 with a new commit: identical, lifetime committed=1e18.

     Next day cycle 3 accept -> rejected with sponsor_exhausted although sponsor spent is still 0.

     Expected: a review that never reached the payment effect returns its share of the lifetime allocation (or never consumes it).

   • mediumsubmitRegistration enqueues unlimited project-register jobs for an already-registered project; each failing job retries forever and starves the shared executor queuesrc/chain-deployments/index.mjs:85

     prepareRegistration returns a new record on every call because the prepared message embeds expiresAt and a nonce derived from it (adapters/chain-read.mjs:93), and there is no per-project cap on chain-registrations.

     The project_already_registered check exists only in prepareRegistration (line 69); submitRegistration never checks chain-bindings or an in-flight registration, so every previously prepared record can be submitted after the project is bound, each enqueuing a project-register job (one owner signature per record, trivially produced by the hostile owner).

     The executor then calls estimateGas on registerProject, which reverts on chain because projects[id].target != 0 (contracts/src/ClausApprovalExecutor.sol:128), a viem error with no code; runOne (lines 139-140) treats every non-authority error as waiting with retryAt now+60s, so the job never terminates.

     Each retry costs a full executor tick (capability getCode, store authorization reads, estimateGas, fee and nonce RPCs). jobs.claim serves one job per tick from a shared scan of all workflow-jobs, so N such jobs delay every legitimate module-deploy and project-register job by roughly N ticks per minute, for every project on the network, at zero cost to the attacker (nothing is signed, no gas reserved).

     The same path also leaves an unbounded number of chain-registrations and chain-registration-signatures documents per project.

     Fix: reject submitRegistration when chain-bindings exists or another registration for the project is queued/running, cap prepared registrations per project, and make a revert from estimateGas on a registration whose project is already bound terminal (blocked).

     whole finding

     Scripted against the real module with mock chain ports: prepare 3 registrations for one pilot project (3 distinct ids), submit #1, write the chain-bindings row (first registration confirmed). prepareRegistration now rejects with project_already_registered, but submitRegistration for #2 and #3 both return state=queued with new job ids. runOne with an executor whose step throws a code-less revert returns state=waiting, error=chain_execution_unavailable, retry in 60000 ms, on every invocation; the jobs never leave queued/waiting. Expected: submission after binding (or while another registration is in flight) is rejected, and a registration that can only revert is blocked, not retried indefinitely.

   • lowChain jobs whose transaction window has closed or whose cost can never fit the public per-transaction gas ceiling are retried every 60 seconds forever instead of being blockedsrc/chain-deployments/index.mjs:139

     Only scope_denied, sponsor_not_enabled and chain_not_enabled are terminal in runOne.

     Two deterministic permanent failures are not: (1) once value.expiresAt (module deploy: createdAt+24h, line 49) or message.expiresAt (registration: prepare+1h, line 65) has passed without a broadcast, sepolia-transactions.prepare throws invalid_transaction (adapters/sepolia-transactions.mjs:45-46) before signing, on every retry; (2) for a public project, admission.reserveGas throws chain_gas_exhausted (src/chain-deployments/admission.mjs:73) whenever gas*maxFeePerGas exceeds maximumTransactionGasWei, which with the planned 0.0002 test-ETH ceiling is reached by any module deploy above about 160k gas at a 1 gwei fee estimate (estimate 160k -> gas 210k -> 0.00021 ETH), and the estimate is re-run every minute with the same outcome.

     In both cases the job stays running/waiting indefinitely, the chain-modules/chain-registrations record stays queued, the public-chain-projects slot consumed by deployModule (line 45) is never released, and the worker spends RPC calls and a claim slot on it every minute.

     Fix: treat invalid_transaction from an expired intent and chain_gas_exhausted below the per-transaction ceiling as terminal (blocked) and record the reason on the module/registration record.

     whole finding

     Public project with maximumTransactionGasWei=200000000000000 (0.0002 ETH): deployModule for an artifact whose creation estimate is 400,000 gas at maxFeePerGas 1 gwei -> prepare computes gas=510,000, maximum=510,000 gwei=0.00051 ETH -> reserveGas throws chain_gas_exhausted -> runOne returns waiting, retryAt now+60000; after 24h the module expiresAt passes and prepare throws invalid_transaction, still waiting every 60 s. Expected: a terminal blocked state with the error recorded on the module.

   • mediumRotating the dispatch budget makes every in-flight delivery throw dispatch_intent_mismatch, which aborts the whole intake worker tick and stalls delivery for all projectsadapters/contract-delivery.mjs:121

     The transaction authority written with each sponsored transaction embeds budgetId and configHash (line 108).

     When the operator later runs the host with a different CLAUS_CONTRACT_DISPATCH_BUDGET (the documented way to replenish after the finite grant is spent or to serve newly admitted projects, since budgets are immutable: lines 9-28), delivery.step for any request that already has a resolve or callback transaction under the previous budget hits this requireThat and throws dispatch_intent_mismatch before any reconciliation. contract-intake-worker only tolerates wallet_busy, dispatch_budget_exhausted, transaction_cost_limit and transaction_not_authorized (runtime/contract-intake-worker.mjs:76-78); every other error propagates out of tick(), so the delivery cursor is not advanced, worker-health is not written (contractIntakeHealth reports worker_unavailable) and the same request is hit on every subsequent tick.

     Requests in this situation are common because a resolve confirmed under the old budget whose callback was still pending, deferred (previous finding) or awaiting finality has delivery.state=pending and is never skipped by the loop filter (line 60). Nothing in the API or host can mark such a request delivered/closed, so the stall is permanent until the database is edited by hand, and no project on the network receives further on-chain results.

     This also contradicts the stated property that an old host must still account for already-broadcast transactions: a replacement budget cannot reconcile them at all.

     Fix: match transactions by their own stored budget (settle old-budget reservations through the old budget row rather than requiring the current configHash), skip rather than throw when a stored transaction belongs to another budget, and have the worker treat dispatch_intent_mismatch as a deferral that still advances the cursor.

     whole finding

     Scripted against the real adapter: budget A admitted; request R1 (project A) resolve broadcast and confirmed under A, callback deferred by transaction_cost_limit (spent 0.000075 ETH, delivery pending).

     Budget B = same config with id budget-B admitted; createContractDelivery({budget: B}).step(R1) throws dispatch_intent_mismatch (stored authority has budgetId A/configHash A). contract-intake-worker tolerates only wallet_busy, dispatch_budget_exhausted, transaction_cost_limit and transaction_not_authorized, so tick() aborts at R1 on every pass before reaching project B request R2, and before writing contract-delivery-cursors or worker-health.

     Expected: R1 is reconciled or skipped under B and R2 is delivered.

   • mediumOne admitted requester can exhaust the shared dispatcher budget through requester-chosen callback gas and request count; no per-project or per-callback ceiling existsadapters/contract-delivery.mjs:103

     The dispatcher sponsors one resolve and one deliverCallback transaction per result. deliverCallback forwards exactly the requester-chosen callbackGas (contracts/src/ClausRequestInbox.sol:46-52 allows up to 1,000,000) and the inbox guarantees the callee receives all of it (line 95), so a callback that burns its whole budget makes the sponsored transaction cost about 1.3M gas after the 1.25x estimate margin.

     Budget accounting (reserve, lines 72-81) checks only the global maximumTransaction and maximumTotal of the single budget; nothing bounds spend per project, per request or per callback, and request volume per project is up to 100 per binding and 32 bindings.

     With the planned 0.0004 test-ETH allocation: at a 0.1 gwei fee estimate a 1.3M-gas callback costs 0.00013 ETH, so three hostile results consume the entire allocation and every other admitted project then gets dispatch_budget_exhausted (deferred forever, contract-intake-worker.mjs:76-78); at 1 gwei the same callback never fits maximumTransaction, the resolve is still broadcast and paid, and the callback is re-estimated and deferred on every worker pass with the request stuck in result_ready.

     Even without callbacks, resolve alone (about 60k gas, 0.00006 ETH at 1 gwei) lets roughly six requests from one project drain the pool. Since all admitted projects share one budget, a single hostile or merely buggy admitted requester crowds out everyone else and no further results can be written on chain until the operator admits a new budget.

     Fix: skip or cap sponsored callbacks above a configured callbackGas (the inbox already lets the requester retry deliverCallback at its own cost), and add a per-project sub-ceiling inside the dispatch budget.

     whole finding

     Scripted against the real adapter with viem signing, budget maximumTotal=0.0004 ETH, maximumTransaction=0.0002 ETH, projectIds=[A,B], hostile callback estimate 1,050,000 gas.

     Regime 1 (fee estimate 1 gwei): pass 1 resolve broadcast (reserved 0.000085 ETH); pass 2 resolve confirmed and finalized, spent 0.000075 ETH, then the callback prepare throws transaction_cost_limit (1,050,000*1.25+10,000 = 1,322,500 gas x 1 gwei = 0.0013225 ETH > 0.0002); pass 3 identical: the request stays result_ready with delivery pending forever and is re-estimated on every worker pass.

     Regime 2 (fee estimate 0.1 gwei): request 1 delivered, spent 0.00013875 ETH; request 2 delivered, spent 0.0002775 ETH; request 3 resolve paid (spent 0.000285 ETH) then callback -> dispatch_budget_exhausted; project B result: resolve still reserved but its callback can never fit the remaining 0.000115 ETH, so B is resolved on chain but never callback-delivered.

     Expected: one project cannot consume the shared allocation, and other projects deliveries continue.

   • lowDispatcher signs a resolve transaction right up to the on-chain deadline, so a late inclusion reverts on chain and the reverted gas is charged to the budgetadapters/contract-delivery.mjs:107

     The resolve intent expires at observation.deadline*1000 with no safety margin, and the submit-time authorization only checks deliveryState at the latest block (pending requires deadline > block.timestamp of the latest block, adapters/contract-intake.mjs:116). ClausRequestInbox.resolve reverts with RequestClosed when block.timestamp >= deadline (contracts/src/ClausRequestInbox.sol:61).

     A transaction signed and broadcast a few seconds before the deadline is included in a later block whose timestamp is at or past the deadline, reverts, and reconcile records state=reverted with actual gasUsed*effectiveGasPrice charged to the dispatcher budget (finalize, lines 82-91) and the delivery marked failed. Requesters choose the deadline freely (minimum 1 second ahead), so short deadlines convert sponsored dispatch into wasted budget.

     Fix: require deadline to exceed the current chain timestamp by a margin (for example the confirmation window plus several blocks) before preparing, and shorten expiresAt accordingly.

     whole finding

     Request with deadline D (seconds).

     Worker tick at chain time D-6s: deliveryState.pending is true (latest block timestamp D-12s < D), prepare passes (expiresAt=D*1000 > now), submit broadcasts.

     Inclusion in the block with timestamp D+6s -> RequestClosed revert -> reconcile writes state=reverted, actual ~25,000 gas x effectiveGasPrice deducted from the budget, delivery.state=failed; the request can no longer be resolved.

     Expected: no transaction is signed when the remaining window is shorter than the expected inclusion delay.

   • lowPublic readonly admission lets any admitted public project create bindings and requests, but result delivery is gated by a fixed projectIds allowlist in the dispatch budget, so public requests are nevadapters/contract-delivery.mjs:54

     contractIntakePorts.admitted in public-readonly-v1 mode (runtime/contract-intake-config.mjs:26-33) admits any project that holds a public-chain-projects row and a matching chain binding, so public projects can bind, have their inbox requests ingested, and consume a full Claus review per request.

     The dispatcher, however, is constructed from one immutable budget whose projectIds list is fixed at admission time (admitContractDispatchBudget, lines 9-28; configHash pins the list) and active() returns false for any project not in it.

     Public projects are admitted dynamically on their first deployModule, so they cannot be in a list fixed earlier; their results reach result_ready and delivery.step returns pending on every pass without ever preparing a transaction, and contract-intake-worker keeps re-evaluating them (chain profile, deliveryState RPCs) on each scan page indefinitely. The requester contract never receives its result, while the operator has already paid for the review.

     Fix: either derive delivery eligibility from the same public admission predicate (with the per-project ceiling from the previous finding) or refuse bind/ingest for projects that the active dispatch budget will not serve.

     whole finding

     Public policy active; project P is admitted via deployModule after the dispatch budget B (projectIds=[pilot]) was installed.

     P binds requester R, R calls ClausRequestInbox.request, the worker ingests it, a proposal is created and decided, contract-requests[id].state becomes result_ready.

     Each worker tick: delivery.step -> active() false (P not in B.projectIds) -> answer(pending); no transaction, no delivery record, repeated on every pass.

     Expected: either P is refused at bind time or its result is delivered under a bounded share of the budget.

   • lowA review case whose paid execution was voided stays in state admitted, so the same source and build can never be re-requested in that projectsrc/review-flow/index.mjs:72

     request() returns any prior case with the same inputHash whose state is admitted or reviewed on the assumption that it is paid or uncertain. After cancelUnsent (runPaid blocked path lines 296-299, or job cancellation via onCancel line 207) the review-jobs row is work=cancelled, billing=void, but the review-cases row is never updated from admitted; get() only overlays the workflow state for display.

     Consequently a project that lost a review to an authority hiccup (for example a transient source_not_published, or an operator-side block) can never request a review of that exact source and build again, and accept() on the old case fails because admitted-quotes already holds the quoteId. The only workaround is to change the input (new commit or build), which breaks the evidence chain the review is meant to pin.

     Case C for input I reaches admitted; runPaid blocks with source_not_published and voids the job (review-jobs: work=cancelled, billing=void).

     Call request() again for the same buildId/repoUrl/baseCommit with a new idempotencyKey: the loop at lines 68-78 hits prior.inputHash===inputHash and prior.state===admitted and returns C instead of creating a new case; runQuote stays idle.

     Expected: a voided case is not treated as paid, and a fresh case for I can be created.

   • lowNo per-project or daily cap on proposal creation: an admitted project can trigger unbounded Claus decision runs (operator-paid inference) through the API or the inboxsrc/approvals/index.mjs:77

     Every proposal enqueues a claus-review job whose controller posts the full review context to the Claus agent (adapters/claus-controller.mjs:55) at the operator expense; the planned pilot explicitly excludes public inference. The only throttle is active-proposals (lines 71-75), which serializes proposals per project but allows a new one as soon as the previous is decided, rejected, failed or blocked, and proposal_create is an ordinary project scope.

     Unlike builds (buildsPerProjectDay), quotes and orders, there is no per-project-per-day or network-per-day proposal counter, and the contract-intake path reaches the same create() with up to 100 requests per binding and 32 bindings per project.

     A rejected decision costs the project nothing and frees the slot immediately, so one admitted public project can run back-to-back decisions all day (dozens to hundreds, bounded only by agent latency), and eight admitted projects multiply that.

     Fix: add a proposalsPerProjectDay / proposalsPerDay admission counter alongside the existing daily quotas, enforced in create() inside the transaction.

     whole finding

     Admitted public project with a verified module and binding: call proposal_create with idempotencyKey k1 and a configuration Claus will reject; wait for chain-proposals[k1].state=rejected (minutes); call proposal_create with k2; the active-proposals check passes because the prior state is rejected, a new claus-review job is enqueued and another agent review runs.

     Repeat with k3, k4, ... without limit and at no cost to the caller.

     Expected: a bounded daily number of decision runs per project and per network, like the existing build and order quotas.

   The review is complete. .imd-findings.json holds 16 merged findings, every one reproduced against this tree with node tests (scratch files since removed) or exact code inspection, and every quoted snippet verified against its path and line.

   What I kept, merged and ranked

   • Medium (8): zero-cost burn of the 4 IMD public lifetime pool by admit-then-cancel (three specialists merged; the existing test documents it as intended, reported because free wallets can retire the programme without sponsor spend); dispatch budget rotation throwing dispatch_intent_mismatch and aborting the intake worker tick (two merged); deterministic gas-cap and expired-window denials after beginEffect leaving uncancellable jobs that retry forever, with the planned cap arithmetic folded in (four merged); relayed or front-run registerProject/execute recorded as permanent failure; lost broadcast locking the shared wallet with no re-broadcast; 5001 cheap inbox events stalling the whole intake worker; one requester's callback gas draining the shared dispatcher budget (two merged); no quota on Claus decision runs (two merged).
   • Low (7): reverted resolve charged to the budget via requester cancel or deadline race (two merged); voided review case stuck admitted (two merged); shared active review pool between public and pilot; expired-pilot projects unmetered; third-party callback leaving requests pending forever; public projects outside the immutable projectIds list never delivered; unlimited submitRegistration after binding.
   • Info (1): the public-scope assessment rows have no writer in the codebase.

   Corrections to specialist claims. The budget-rotation finding claimed ingestion stops; scan, ingest and intake.run actually execute before the delivery loop, so only delivery, cursor and health writes stall. I stated that precisely. The economics specialist's per-project allocation arithmetic was not a code defect on its own, so it is folded into the gas-cap finding rather than kept separately.

   Scope limits. No proofs were attached because no finding is a critical or high defect in Solidity; the contract code checked (ClausRequestInbox, ClausApprovalExecutor) behaved as the findings assume. No on-chain or Anvil run was performed; the relay and revert cases were reproduced with stubbed receipts plus contract inspection. The working tree is clean apart from the findings file, and node_modules is gitignored.

     createReviewAdmission.reserve() (lines 44-54) adds quote.offer.maximum to the single 'public-review-exposure/lifetime' counter and increments the per-owner day counter inside beforeAdmission, i.e. at admission time, before any payment effect. Nothing ever subtracts from these counters, nor from the public per-project/global day keys written at src/review-flow/index.mjs:182-190.

     Sign-in is a free Ethereum signature, projects and builds are free, job.cancel is an owner scope, and perOwnerDay is per owner address, so four throwaway wallets x 2 admissions x 0.5 IMD exhaust the planned 4 IMD lifetime pool in one day without the sponsor paying for a single review; every later public accept fails with sponsor_exhausted until the owner publishes a policy with a larger maximumLifetime (which also raises the real spending cap because the counter cannot distinguish voided from spent commitments).

     The same loop burns the 8/day global allocation each day. test/review-flow.test.mjs:208-216 asserts the post-cancel exhaustion as intended ('never creates unfunded credit'), so this is a documented design choice, reported because it lets unfunded callers crowd every legitimate project out of the public programme. The chain admission module keeps separate reserved/spent figures and releases on cancel (src/chain-deployments/admission.mjs:84-96); the review module does not.

     Minimal fix: release the lifetime exposure and the owner/project/global day counters in cancelUnsent/abandonUnsent (keyed by jobId so the release is idempotent) or move the exposure reservation to the effect boundary; alternatively track reserved and spent separately as the chain admission does.

   • mediumReplacing the dispatch budget makes every in-flight delivery throw dispatch_intent_mismatch, which aborts the whole intake worker tick and never settles the old reservationadapters/contract-delivery.mjs:121

     Every dispatcher transaction intent embeds the budget identity (line 108: authority = { kind, requestId, resultHash, action, budgetId: budget.id, configHash }). When step() later finds an existing chain-transactions row for the request it requires digest(transaction.intent.authority) === digest(authority) (lines 121-124) and throws dispatch_intent_mismatch otherwise.

     Budgets are immutable and the planned pilot has no auto-refill, so the documented way to continue after the finite grant is spent or expired, or to serve newly admitted projects, is to admit a new budget id and point CLAUS_CONTRACT_DISPATCH_BUDGET at it (runtime/contract-intake-host.mjs:23).

     Any contract-requests row still in result_ready with delivery.state pending (normal for the ~15 minutes between a confirmed resolve and Sepolia finality, while a resolve/callback is submitted/unknown, or while a callback is deferred by transaction_cost_limit) carries a transaction signed under the old budget id. runtime/contract-intake-worker.mjs:76-78 only tolerates wallet_busy, dispatch_budget_exhausted, transaction_cost_limit and transaction_not_authorized; dispatch_intent_mismatch propagates out of tick() before contract-delivery-cursors and worker-health are written, so the hosted handler answers 503, contractIntakeHealth reports worker_unavailable, every row sorted after the stuck one is never stepped again, and the old budget's reserved amount is never settled into spent (contradicting the immutable-historical-spending requirement and the comment at worker lines 65-67, which only holds for revokeContractDispatchBudget on the same id).

     Scan, ingest and intake.run() do still execute earlier in the tick.

     Minimal fix: when an existing transaction belongs to another budget, reconcile and finalize it against the budget id stored in its intent (or skip it) instead of throwing, and treat dispatch_intent_mismatch as a deferral in the worker. Merged from audit_flow and audit_math.

     whole finding

     Reproduced with node --test against this tree using the contract-delivery fixture pattern: budget-1 admitted; request R (project-a) stepped once -> resolve broadcast, ledger budget-1 reserved '135000000000'.

     Admit budget-2 = same config with id 'budget-2'; confirm the resolve on the stub chain; createContractDelivery({ budget: budget-2 }).step(R) rejects with code 'dispatch_intent_mismatch'; budget-1 stays reserved '135000000000' spent '0'.

     Wrapping the same delivery in createContractIntakeWorker and calling tick() twice rejects both times with 'dispatch_intent_mismatch', contract-delivery-cursors stays empty and R.delivery is never written.

     Expected: R is reconciled under its original budget and later rows keep being delivered.

     runOne (line 113) and approvals.runExecution (src/approvals/index.mjs:174) call jobs.beginEffect on the first dispatch, flipping the job to effect 'outcome_unknown' before any transaction is prepared.

     If sepolia-transactions.prepare then fails deterministically - admission.reserveGas throws chain_gas_exhausted when gas*maxFeePerGas exceeds maximumTransactionGasWei or the project/total ceiling (src/chain-deployments/admission.mjs:73-79), prepare throws transaction_cost_limit, or invalid_transaction once value.expiresAt / message.expiresAt has passed (adapters/sepolia-transactions.mjs:45-46) - none of these codes is in the blocked list here or at src/approvals/index.mjs:193 and none is in adapters/authorization.mjs authorityDenied, so the job is finished 'waiting' with retryAt now+60s and re-claimed every minute indefinitely, re-running estimateGas/estimateFeesPerGas/getTransactionCount/getBalance each time.

     Nothing was signed or broadcast, yet jobs.cancel now refuses with effect_requires_reconciliation (src/jobs/index.mjs:50); the chain-modules/chain-registrations row stays 'queued', the public-chain-projects slot consumed by deployModule is never released, and for protected-execute the active-proposals lock keeps approvals.create rejecting with proposal_in_progress.

     With the planned ceilings this is the expected steady state rather than an edge case: gas = estimate1.25+10000, so a registerProject that creates a ClausReadonlyProject (several hundred thousand gas) exceeds the 0.0002 test-ETH per-transaction cap whenever Sepolia maxFeePerGas is above roughly 0.4-0.6 gwei, a project needs at least deploy+register (and queue+execute for one upgrade) inside 0.0005, and 8 x 0.0005 = 0.004 exceeds the 0.002 total (the schema does not check maximumProjectsmaximumProjectGasWei <= maximumTotalGasWei), so projects five to eight hold a slot but every reserveGas fails.

     Minimal fix: add chain_gas_exhausted, transaction_cost_limit and the expired-window invalid_transaction to the blocked lists (they are deterministic policy denials with no external effect) and record the reason on the module/registration/proposal row, or run the reservation check before beginEffect; validate the policy arithmetic in the chain.admission schema.

   • mediumA relayed or front-run registerProject/execute makes the executor's own transaction revert and the off-chain record becomes a permanent 'failed' although the on-chain change succeededadapters/chain-executor.mjs:59

     ClausApprovalExecutor.registerProject and execute are permissionless relays of an owner or Claus signature (contracts/src/ClausApprovalExecutor.sol:125,154): anyone who sees the calldata in the public Sepolia mempool (the executor broadcasts via sendRawTransaction at adapters/sepolia-transactions.mjs:110) can submit it first.

     The relayed call registers (or upgrades) the project, and the executor's own transaction then reverts with InvalidRegistration (projects[r.projectId].target != address(0), Solidity line 128) or AlreadyExecuted (line 254). terminal() maps every reverted transaction to { state: 'failed' } without reading chain state.

     For project-register, runOne writes chain-registrations[id].state = 'failed' and never writes chain-bindings; prepareRegistration recomputes the same projectKey = keccak(owner, keccak(projectId)) (adapters/chain-read.mjs:89-90) so every later registration for that project reverts for the same reason and the executor pays gas for each reverted attempt: the project can never use the chain path.

     For execute, the relayed-execution handling at lines 155-168 (executionNonces + UpgradeExecuted log) is only reached when no 'execute:' row exists; once the executor's own execute transaction has reverted (lines 139-146), the proposal is marked failed while the target already runs the new implementation, so the recorded public evidence is wrong.

     Cost to the attacker is one Sepolia transaction with a higher priority fee; the owner relaying its own signed registration triggers the same outcome accidentally.

     Minimal fix: on a reverted register:/execute: transaction read projects[projectKey] (or executionNonces + the UpgradeExecuted log as lines 155-168 already do) before classifying the result, and treat an on-chain state equal to the signed message as success.

     whole finding

     Contract side (by inspection of contracts/src/ClausApprovalExecutor.sol:128 and 254): the second registerProject with the same Registration reverts because projects[r.projectId].target is already set; the second execute with the same Approval reverts because executionNonces[a.projectId][a.nonce] is set.

     Off-chain side reproduced with node --test against this tree: createChainDeployments + createChainExecutor with a stub client where the register transaction is mined with receipt status 'reverted' (what the executor observes after a relayer landed the same calldata first).

     Sequence: prepareRegistration -> submitRegistration -> runOne (state 'waiting', 1 broadcast) -> receipt confirmed as reverted -> runOne returns state 'failed' with result.error 'transaction_reverted'; chain-registrations[id].state === 'failed'; chain-bindings for the project is null; a subsequent prepareRegistration succeeds and produces a new record whose registerProject would revert again for the same reason.

     Expected: the executor compares projects[projectKey] with the signed message and records the registration as verified / writes chain-bindings.

   • mediumA single lost broadcast (RPC timeout on sendRawTransaction) permanently locks the shared executor or dispatcher wallet: the sealed transaction is never re-broadcast and no path releases the slotadapters/sepolia-transactions.mjs:91

     submit() broadcasts the sealed raw transaction exactly once.

     If client.sendRawTransaction throws (the production transport is http('https://ethereum-sepolia-rpc.publicnode.com', { retryCount: 0, timeout: 15000 }) in runtime/chain-worker.mjs:18 and runtime/contract-intake-config.mjs:14, so one 15 s timeout or transient 5xx suffices), the record is moved to state 'unknown' (line 114) and every later submit() returns at this line because the state is no longer 'prepared'. reconcile() only polls getTransactionReceipt for the stored hash and returns silently while no receipt exists (line 123).

     The chain-wallet-slots entry keeps id = this transaction, so every later prepare() for any project and any job kind fails with wallet_busy (line 66). There is no re-broadcast of the identical bytes (safe: same hash and nonce), no expiry-based cancellation after an uncertain send, no nonce-gap detection (getTransactionCount would show the nonce unconsumed) and no operator API to clear the slot.

     The executor key is shared by all public and pilot projects and the dispatcher key by all intake projects, so one network hiccup halts chain execution or result delivery network-wide until someone edits the database and broadcasts the sealed bytes by hand. test/sepolia-transactions.test.mjs:34-47 asserts broadcasts === 1 after restart, so refusing to replace is intentional, but refusing to resend the same bytes is a liveness defect.

     Minimal fix: when state is 'unknown' or 'submitted' and reconcile() finds no receipt, re-open the sealed raw and sendRawTransaction again (treat 'already known' as success); additionally, once intent.expiresAt has passed and getTransactionCount('latest') <= nonce, cancel the record and release the slot.

     Reproduced with node --test against this tree: createSepoliaTransactions with a stub client whose sendRawTransaction throws once without the node receiving the bytes. prepare('first') then submit('first') -> state 'unknown'.

     A new instance whose now() is one day later (intent expired) still does not re-broadcast or release: prepare('third') rejects with 'wallet_busy'.

     Expected: the identical sealed bytes are re-broadcast, or the slot is released once the nonce is provably unconsumed and the intent expired.

     ClausRequestInbox.request is permissionless (any binding word, 1-byte input, no fee, contracts/src/ClausRequestInbox.sol:46-56). createContractInboxRead.scan fetches every Requested log in a fixed 500-block window (the worker never passes a smaller limit, runtime/contract-intake-worker.mjs:23) and throws inbox_scan_too_large when more than 5000 logs are returned.

     The worker awaits scan() outside any try block, before the cursor write, before intake.run() and before the delivery loop, so the whole tick aborts: the cursor never advances past the spam range, no proposal is created, no result_ready request is resolved, and already-broadcast dispatcher transactions are never reconciled (wallet slot and budget reservation stay held); worker-health is not written so /health reports worker_unavailable.

     There is no backoff, window shrink, pagination or per-binding filter, so every subsequent tick fails identically until an operator hand-edits the cursor (losing legitimate events in that range, which then expire at their deadline). Cost is Sepolia test ETH only: a helper contract calling inbox.request() in a loop needs roughly 300M gas in total (about 9-11 transactions at the block gas limit) inside ~100 minutes.

     Minimal fix: catch inbox_scan_too_large in scan(), halve the block window and retry (or page getLogs by sub-ranges), and run the delivery/reconciliation loop even when scan fails.

     The dispatcher budget is one global ledger (contract-dispatch-budgets[budget.id]): admitContractDispatchBudget takes a projectIds list but no per-project ceiling, and reserve() (lines 72-81) checks only maximumTransaction and the global maximumTotal.

     The size of a sponsored callback is chosen by the requester: ClausRequestInbox.request accepts callbackGas up to 1,000,000 and deliverCallback forwards exactly that much (contracts/src/ClausRequestInbox.sol:28,93-99), so sepolia-transactions.prepare reserves about 1.32M gas (estimate1.25+10000) for a callback that burns its budget, and reconcile books the actual gasUsedeffectiveGasPrice as immutable spent.

     With the planned 0.0004 test-ETH total and 0.0002 per transaction: at ~0.1 gwei a 1.05M-gas callback costs ~1.05e14 wei, so two requests from one project (resolve+callback each) consume more than half of the allocation and the next resolve of any other project fails reserve() with dispatch_budget_exhausted, which the worker only defers (runtime/contract-intake-worker.mjs:76) until the request deadline closes the on-chain request; at ~1 gwei the same callback never fits maximumTransaction, the resolve is still paid and the callback is re-estimated and deferred on every pass.

     Request volume per project is up to 100 per binding x 32 bindings, and even resolve-only requests (~60k gas) let one project drain the pool. Spending is immutable and there is no refill, so a hostile or merely gas-hungry admitted project denies result delivery to every other admitted project for the rest of the pilot.

     Minimal fix: carry a per-project sub-allocation in the budget config and check it in reserve(), and cap accepted callbackGas per project in createContractIntake.ingest (observation.callbackGas) or skip sponsored callbacks above a threshold (the inbox already lets the requester retry deliverCallback at its own cost).

     Every paid or gas-bearing resource in the pilot has a counter (public-review-exposure, review-admission day keys, public-chain-usage, dispatch budget), but the Claus decision has none. approvals.create requires only proposal.create + proposal.execute scopes and chain admission, serializes proposals per project through active-proposals, and enqueues a claus-review job whose controller posts the full input (all snapshot files, the review report and the proposal, bounded only by review_context_too_large at 900,000 bytes, line 64) to https://claus-agent.vercel.app/internal/network/reviews (adapters/claus-controller.mjs:18,55).

     A rejected decision is terminal and costs the project nothing, and job_cancel on decisionJobId is allowed while the controller has not claimed it, so the slot is released immediately and the next proposal can be created with a fresh idempotencyKey. src/access/index.mjs defines buildsPerProjectDay, quotesPerProjectDay, ordersPerProjectDay and similar, but no proposals-per-day limit exists in src/access, src/approvals or src/chain-deployments; the only other throttles are the HTTP peer rate limit and the one-at-a-time rule.

     The contract-intake path reaches the same create() with up to 100 requests per binding and 32 bindings per project. docs/testnet.md:27 describes queued Claus requests as purchased inference, so the owner's 'no public inference' constraint is violated indirectly as soon as public chain admission opens: each of the eight admitted projects can run back-to-back decisions all day at operator expense.

     Minimal fix: add a per-project-day and global-day proposal counter (same pattern as the review-admission keys) enforced inside create()'s transaction and in contract-intake ingest, published in the chain.admission policy. Merged from audit_permissions and audit_math.

     Sequence for an admitted project P with verified module M and binding: proposal_create {moduleId:M, configuration:'0x'+i padded, idempotencyKey:'k'+i}; wait for state rejected (or job_cancel decisionJobId before the controller claims it); repeat with i+1.

     The delivery authorize() callback checks chain.deliveryState(request).pending (state Pending and deadline > latest block timestamp) at prepare and at submit, and the resolve intent expires exactly at observation.deadline*1000 with no safety margin (line 107).

     The request can still be closed between broadcast and inclusion: ClausRequestInbox.cancel() is callable by the requester at any time while Pending (contracts/src/ClausRequestInbox.sol:69-75) and resolve() reverts with RequestClosed once block.timestamp >= deadline (line 61).

     A reverted transaction is still mined, so sepolia-transactions.reconcile calls onFinalize with actual = gasUsed*effectiveGasPrice (lines 141-142) and finalize() adds it to the immutable budget.spent; step() returns 'failed' and the request is never retried.

     A bound requester can repeat this (cancel the moment the dispatcher's resolve appears in the mempool, or pick a deadline a few seconds after the expected delivery) across up to 100 requests per binding; each attempt costs the attacker one cheap Sepolia transaction and costs the shared 0.0004 test-ETH allocation one reverted resolve. Impact is limited to disabling result delivery for the other admitted projects until a new budget is installed by hand.

     Minimal fix: require deadline - now >= a safety margin in intake.ingest() before creating a proposal, re-check pending immediately before sendRawTransaction, and cap failed deliveries per binding. Merged from audit_economics and audit_math.

     Next step() returns state 'failed'; ledger spent === '25000000000' (25000*1e6) and reserved '0'; a further step() stays 'failed'.

     Contract side by inspection: cancel() has no restriction while Pending and resolve() reverts at or after the deadline.

     The pilot flag therefore is not a kill switch and the 0.002 test-ETH public total is not the real exposure of the executor key while any pilot-era project exists.

     When the dispatcher reaches the callback action with no transaction of its own and sees callbackDelivered = true it returns 'pending' rather than a terminal state. runtime/contract-intake-worker.mjs:60 treats only delivered/closed/failed as terminal, so the request is stepped again on every tick for the life of the deployment (chain.profile, chain.resolution, submit() of the already-confirmed resolve and deliveryState reads), and contract_request_get keeps reporting delivery.state 'pending' although the on-chain request is Completed and the callback was delivered.

     The comment says such a send is left for operator reconciliation, but there is no operation to record it.

     Minimal fix: return a terminal state (e.g. delivered with external: true, or closed) when observed.callbackDelivered is true for the callback action.

     whole finding

     Reproduced with node --test against this tree: createContractDelivery fixture with a callback; step() broadcasts the resolve; the stub chain confirms it and then reports callbackDelivered = true before any callback transaction exists.

     Three consecutive step() calls each return state 'pending'; broadcasts stay 1 and only the resolve row exists in chain-transactions.

     Expected: the worker records delivery once and stops scheduling the request.

   • lowPublic readonly admission lets any admitted public project bind and have requests decided, but delivery is gated by the immutable projectIds list of the dispatch budget, so their results are never deladapters/contract-delivery.mjs:54

     contractIntakePorts.admitted in public-readonly-v1 mode (runtime/contract-intake-config.mjs:26-33) admits any project with a public-chain-projects row and a matching binding, so public projects can bind, have inbox requests ingested and consume a full Claus decision per request.

     The dispatcher is constructed from one immutable budget whose projectIds list is fixed at admission time (configHash pins it, lines 9-28) and active() returns false here for any project not in the list, after which step() returns 'pending' (line 132) without preparing a transaction.

     Public projects are admitted dynamically on their first deployModule, so they cannot be in a list fixed earlier; their requests reach result_ready and are re-evaluated by the worker on every pass indefinitely while the requester contract never receives its result and the operator has already paid for the review.

     Minimal fix: derive delivery eligibility from the same public admission predicate (with a per-project ceiling), or refuse bind/ingest for projects the active dispatch budget will not serve.

     whole finding

     Reproduced with node --test against this tree: createContractDelivery with budget projectIds ['pilot-only'] and a result_ready request for 'project-a' that passes admitted().

     Three consecutive step() calls return state 'pending'; zero broadcasts; chain-transactions stays empty.

     Expected: either P is refused at bind time or its result is delivered under a bounded share of the budget.

   • lowsubmitRegistration accepts any number of prepared registrations, including after the project is bound; each impossible one retries forever and pollutes the shared executor queuesrc/chain-deployments/index.mjs:83

     prepareRegistration returns a new record on every call because the prepared message embeds expiresAt and a nonce derived from it (adapters/chain-read.mjs:93), and there is no per-project cap on chain-registrations.

     The project_already_registered check exists only in prepareRegistration (line 69); submitRegistration checks neither chain-bindings nor an in-flight registration, so every previously prepared record can be submitted after the project is bound (or several at once before it), each enqueuing a project-register job.

     For all but the first, registerProject reverts on chain (projects[id].target != 0, contracts/src/ClausApprovalExecutor.sol:128), so estimateGas throws a code-less viem error; runOne (lines 139-140) treats every non-authority error as waiting with retryAt now+60s and the job never terminates, costing executor RPC calls each minute and delaying other jobs because jobs.claim serves one job per tick from a shared scan.

     Nothing is signed and no gas is reserved, so this is free for the owner.

     Minimal fix: reject submitRegistration when chain-bindings exists or another registration for the project is queued/running, cap prepared registrations per project, and make a revert from estimateGas on a registration for an already bound project terminal (see also the finding on deterministic denials retried forever).

     whole finding

     Reproduced with node --test against this tree: createChainDeployments with mock chain ports; prepareRegistration three times for one project at different seconds yields 3 distinct ids; submit #1; write the chain-bindings row (first registration confirmed). prepareRegistration now rejects with project_already_registered, but submitRegistration for #2 and #3 both return state 'queued' with new jobs. runOne with an executor whose step throws a code-less revert returns state 'waiting', error 'chain_execution_unavailable' on every invocation; three project-register jobs remain non-terminal. Expected: submission after binding is rejected and a registration that can only revert is blocked, not retried indefinitely.

   • infoPublic-scope approval records (chain-admission-assessments, contract-intake-admissions) have no writer; public admission opens on an unvalidated manual database rowsrc/chain-deployments/admission.mjs:42

     admitted() and contractIntakePorts.admitted() (runtime/contract-intake-config.mjs:21-27) gate the whole public chain and intake path on chain-admission-assessments and contract-intake-admissions rows carrying accepted, publicAdmission, executorCodeHash, reviewArtifactHash and reviewedBuildHash. No module, service operation, CLI command or script in the repository writes either collection (only tests do); they can only be inserted directly into the database.

     Unlike policy.publish/activate these rows get no schema validation, no owner-credential check, no expectedGeneration compare-and-set and no audit event, and the reviewCaseId they reference is a review of the project named in the policy, not necessarily of the executor bytecode whose hash they assert.

     This is a trust assumption rather than a bypass (database write access already controls the ledger), but the explicit requirement that 'a previous narrow single-project audit is not public-scope approval' is enforced only by operator discipline, and discovery/health report public_readonly the moment the row exists.

     Suggested handling: an owner-authorized, schema-validated, evented assessment.record operation that binds the executor code hash to a review case whose build hash equals the executor artifact.

     whole finding

     grep -rn 'chain-admission-assessments|contract-intake-admissions' over the tree excluding test/ returns only the two readers (src/chain-deployments/admission.mjs:42, runtime/contract-intake-config.mjs:21).

     Sequence: chain.admission policy published and activated with reviewCaseId C of any reviewed case; admitted() throws chain_scope_not_reviewed as intended; inserting one document in chain-admission-assessments with id digest({ executor, targetArtifactHash, reviewCaseId: C }) and body { accepted: true, publicAdmission: true, chainId: 11155111, executorCodeHash, reviewArtifactHash: C.artifactHash, reviewedBuildHash: C.input.buildHash } (exactly what test/public-chain-admission.test.mjs:27-32 does) makes admitted() succeed and any project may module_deploy into one of the eight slots.

     Expected: a recorded, authorized, auditable decision tied to the executor bytecode.
