Review the exact corrected Claus paid-agreement candidate at commit …fdf7534f

Review the exact corrected Claus paid-agreement candidate at commit be5069c2e7cded57f786657a36453afe2aa98f2d. This distinct review concerns the corrections to prior IMD job b9c4399e-2616-411c-86e3-415b1e889f29 on source935c323e5190ce9806e1b844a3644b5519200487. Compare the delta and read docs/deal-audit-response.md. Do not mistake the earlier report for approval of these changes. The escrow Solidity and existing native TS are unchanged; focus on actual corrected offchain financial paths rather than repeating unchanged full suites. Verify durable case admission independent of requester-session veto, original-party and operator revocation boundaries, explicit missing/wrong-kind buyer objections without made-up payout evidence, per-owner and minimum-value subsidy limits, admission vs processing time margins, atomic release ONLY of never-submitted reservations while preserving all ambiguous submissions, mandatory chain-verified amount pins, actual separate-worker cron configuration and fresh-health admission. Review the shared decision validator and independent IMD/native/signer bindings end to end; exact native snapshots are in reference/deal-review-native. Run focused reproductions on these changed boundaries. All financial activation remains disabled pending final assessment and the real owned lifecycle. No deployment, purchase, transaction, grant or public safety guarantee is requested. Report concrete bugs and remaining assumptions.

Also review the prepared-input wire binding: a real unpaid IMD quote confirmed inputHash covers {request,pinned,questionHash}, not the bare request. The adapter validates exact case inputs and canonical confirmed block hash before reserving/payment; proof and native host consume the same stored prepared input. Reject changed amount/question/window/consumer/allowAmbiguous, preserving original order on uncertain outcomes. The unpaid format probe had no payment or panel.

1.highAny transient failure inside permitted()/stillAllowed() is converted into a permanent authority_closed block of a possibly paid casesrc/deals/arbitration.mjs:21
```
 async function permitted(v,reader=store){try{const p=await admission(reader);return p.generation===v.admissionGeneration;}catch{return false;}}
```
permitted() wraps the store read of network-capabilities/deal-arbitration in a catch-all that returns false. tick() treats false as authority_closed and saves the case as state blocked (line 41), and this commit also added authority_closed to the permanent-error list (line 46), so the same catch-all now governs every stillAllowed() call inside advance(): before quote, before prepare, before submit and three times around signing.

One transient database error on that single read (Neon websocket drop, ECONNRESET, statement timeout) therefore permanently blocks the case, removes it from the active list and never retries it, although the operator capability is still enabled with the unchanged generation.

One permanent case ID exists per deal, so the agreement loses its only subsidized review; when the failure happens after submit the IMD oracle fee already paid is lost too, and the per-owner lifetime allowance and global eight-case slot stay consumed. At 935c323 a throw from inside advance was retryable.

Fix: let read failures propagate (or return a distinct unknown value) from permitted(), and reserve authority_closed for an actually observed generation change or enabled:false in the admission record; keep infrastructure errors non-permanent.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R2: case admitted, capability {enabled:true,generation:1} unchanged; the store passed to createArbitration is a Proxy whose read of network-capabilities rejects exactly once (asserted failed===1) and succeeds afterwards.

Expected: case stays queued and is retried next tick.

Actual: deal-cases[id].state==="blocked", error==="authority_closed", the id is removed from deal-case-capacity.active, ports.advance is never called and a second tick does not resume it.

The second half of R2 injects the same single failure during stillAllowed() inside advance and gets the same permanent block.
2.mediumDeal worker heartbeat is written even when the worker cannot process cases, so fresh-health admission keeps admitting and every admitted case is burnedapi/deals.mjs:21
```
  await ports.reconcile();const result=await deals.tick();await store.transaction(async tx=>{const old=await tx.read('worker-health','deals');await tx.write('worker-health','deals',{observedAt:Date.now(),durationMs:Date.now()-start,processed:result.processed,release:process.env.CLAUS_NETWORK_RELEASE},old?.revision??0);});res.status(200).json({ok:true,...result});
```
The public API and the signer worker are separate deployments with separate copies of CLAUS_DEAL_ARBITRATION_ENABLED and CLAUS_DEAL_PINS.

Admission only requires worker-health/deals.observedAt within five minutes (src/deals/arbitration.mjs:16,30). api/deals.mjs writes that heartbeat unconditionally after reconcile()+tick(), including when its own createArbitration was built with enabled:false (flag unset or not "1") or when dealPorts() fell back to its stub because the pins are invalid.

With the flag off, tick() -> permitted() -> admission() throws deal_arbitration_disabled, permitted returns false and every active case is saved as blocked/authority_closed on its first tick without ever calling ports.advance.

Meanwhile the public API keeps reporting capabilities.deals.arbitration.enabled=true and request() keeps admitting; each admission consumes one of the eight lifetime subsidy slots, the owner daily/total allowance and the deal's single permanent case ID, none of which is refunded. docs/paid-deals.md says new admission rejects a worker that cannot process, but nothing in the heartbeat carries the worker's enabled flag, pin configuration or admission generation.

Fix: record the worker's effective enabled flag (and ideally the generation it is serving) in the heartbeat and require enabled===true in workerHealth(); or skip the heartbeat when the flag is off or the pins are invalid.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R1: two createArbitration instances on one store; the API side has enabled:true, the worker side enabled:false, capability {enabled:true,generation:1}.

Worker tick then heartbeat write (the api/deals.mjs order), API discovery().enabled===true, API request() returns state queued, worker tick+heartbeat again.

Expected: request rejected with deal_worker_unavailable, or the case left queued until a configured worker exists.

Actual: case state blocked, error authority_closed, advance count 0, deal-case-capacity.total===1, deal-case-daily principal::total===1, a repeat request returns the dead blocked case, and discovery().enabled is still true.
3.mediumreleaseUnsent cancels prepared payments that are still submittable or merely paused, and advance() then mislabels the case authority_closedruntime/arbitration-ports.mjs:18
```
 async function releaseUnsent(offerId){return store.transaction(async tx=>{const row=await tx.read('deal-oracle-allocations',offerId);if(row?.value.billing!=='reserved')return false;const a=row.value;if(await allowed(a.caseId,tx)&&a.offer.expiresAt>now()+60000)return false;if(!await payment.abandonUnsent(tx,offerId))return false;await settleReservation(tx,ACCOUNT,ASSET,a.maximum,'0');await tx.write('deal-oracle-allocations',offerId,{...a,billing:'released-unsent',releasedAt:now(),reason:'No submit intent existed; original offer retained.'},row.revision);return true;});}
```
reconcile() runs releaseUnsent for every reserved allocation, before tick() and without taking the case lease.

It cancels any payment in signing/signing_unknown/prepared state as soon as (a) offer.expiresAt<=now()+60000, although submit() still accepts until deadline>now+15 and a concurrent invocation (minute cron, 300 s maxDuration) may already have passed the line-29 check and be between prepare and submit; or (b) allowed(caseId) is false, which includes a temporary operator enabled:false with the same generation.

When advance() later reads payment.status() it finds cancelled and throws authority_closed (line 29), which this commit made permanent.

Three consequences: a payment that was about to be submitted is killed and the deal's single case is lost; an expired never-submitted quote is recorded on the public case as authority_closed instead of oracle_quote_expired, because reconcile runs before tick (the oracle_quote_expired branch is unreachable in the api/deals.mjs order); and a brief operator pause that does not bump the generation permanently kills every in-flight prepared case on re-enable, which docs/paid-deals.md does not state.

Money is not lost (the submit fence holds), but the label is wrong and the case outcome is wrong.

Fix: release on expiry only once nothing can be submitted any more (expiresAt<=now(), i.e. after the submit deadline) and skip allocations whose case holds an unexpired lease; check offer expiry before the cancelled check so the public error is oracle_quote_expired; and either document that an operator pause is terminal for admitted cases or release only when the case is terminal or the offer has really expired.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R4: admitted case oracle-pending, allocation q1 reserved, offer.expiresAt=now+50000, imd-payments q1 state prepared with deadline now+40s (submit would accept). ports.reconcile() -> imd-payments q1 state cancelled, allocation released-unsent while deal-cases state is still oracle-pending; ports.advance(v) then rejects with authority_closed although the capability record is still enabled.

Test R5: same with offer.expiresAt=now-1; reconcile then tick (api/deals.mjs order) leaves the case blocked with error authority_closed, not oracle_quote_expired.

Test R6: offer expiring in 500 s, operator sets enabled:false with the same generation, reconcile cancels q3; operator sets enabled:true; advance rejects with authority_closed and the case is permanently blocked.
4.lowNetwork-wide access-policy pause and admin project suspension do not stop an admitted case although the published description says operator suspension doessrc/deals/arbitration.mjs:21
```
 async function permitted(v,reader=store){try{const p=await admission(reader);return p.generation===v.admissionGeneration;}catch{return false;}}
```
At 935c323 permitted() also called identity.allowed(v.actor,"deal.review",...), which returns false when the active access policy has paused:true (writesEnabled in api/deals.mjs) or project-access is suspended.

The correction removed that call to make admission durable against requester-session revocation, but with it removed the only link between the operator's global pause and the financial worker. tick() now keeps quoting, signing, paying, posting to the native host and signing resolutions while the whole network is paused, and project_access_set {suspended:true} by the operator has no effect either (test/deal-arbitration.test.mjs:15 asserts the continuation).

The only operator action that stops a case is editing network-capabilities/deal-arbitration. docs/openapi.json:727, interfaces/contract.mjs:22 and docs/paid-deals.md say "network operator suspension still stops it" without saying that neither the global pause nor project suspension counts.

Either consult the access policy paused flag in permitted() (it is operator-controlled, not requester-controlled, so it does not reintroduce the party veto) or document that only the deal-arbitration capability record stops processing.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R3: admitted case queued, worker health fresh, capability enabled.

The owner publishes and activates an access policy with paused:true; access_policy_get returns paused===true and identity.allowed(actor,"deal.review",{projectId}) returns false. tick(): expected (behaviour at 935c323 and the documented operator suspension) no advance and authority_closed; actual: advance is called once and the case moves to oracle-pending.
5.lowreconcile() reads at most eight allocation rows with no cursor, so later reservations are never released or settledruntime/arbitration-ports.mjs:58
```
  async reconcile(){for(const row of await store.list('deal-oracle-allocations',{limit:8})){const a=row.value;if(a.billing!=='reserved')continue;try{if(await releaseUnsent(a.offer.id))continue;const old=await payment.status(a.offer.id);if(!old||old.state==='cancelled')continue;const state=await payment.reconcile(a.offer.id);await settleCost(a.offer,state,a.inputHash);}catch{}}}
```
store.list returns rows ordered by id with limit 8 and the loop never pages with the after cursor. Rows already settled or released still occupy those eight slots, so any allocation whose id sorts after the first eight is never visited: an expired never-submitted reservation is never released and a submitted payment is never reconciled or cost-settled from this path.

Today the lifetime cap of eight cases keeps the bound latent, but it silently breaks once the cap is raised, a second chain pin shares the store, or a case ever produces a second offer row.

Fix: page with the after cursor until fewer than limit rows return, or iterate only billing=reserved rows.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R7: nine deal-oracle-allocations rows a1..a9, all billing reserved with offer.expiresAt in the past and a caseId that does not exist (so releaseUnsent should release each), 9000 units funded and 9x1000 reserved. ports.reconcile() five times.

Expected: all nine released-unsent, reserved balance 0.

Actual: a1..a8 become released-unsent, a9 stays reserved and the balance stays reserved:"1000" after any number of runs.
6.lowDeterministic verification failures and provider-format mismatches are retried every minute with provider calls and never reach a terminal statesrc/deals/arbitration.mjs:46
```
    }catch(e){const permanent=['deal_not_reviewable','deal_state_changed','deal_pin_mismatch','deal_evidence_mismatch','oracle_quote_expired','authority_closed'].includes(e.code);await save(id,token,{...(permanent?{state:'blocked',error:e.code}:{}),lease:null}).catch(()=>{});}
```
Only six error codes are permanent. Errors that depend solely on already-checkpointed or deterministic state are retried for the life of the dispute window: oracle_prepared_input_mismatch, oracle_question_mismatch, oracle_attestation_mismatch, oracle_signature_invalid, oracle_amount_invalid (all raised by verifyDealOracle on the stored v.oracle), case_binding_mismatch, oracle_admission_mismatch, native_binding_mismatch and a native host 400.

Each retry costs a provider status GET and, for native rejections, a fresh POST of the full input; the case also keeps its active slot and part of the 300 s tick budget until resolutionDue-3600 passes and deal_not_reviewable blocks it.

The same shape exists one step earlier in adapters/imd-oracle.mjs:94: quote() only persists {quote,preparedInput} after the unpaid 402 probe passes validateOraclePrepared, whose shape() requires exactly the keys {pinned,questionHash,request} and {fromBlock,toBlock,toBlockHash}; if the provider wrapper ever carries one extra key the validator throws before the store write, the order row stays at quote:null and every later tick POSTs /requests/quote and the /submit probe again with no terminal outcome.

Rejecting a changed wrapper is correct; the missing piece is a recorded terminal failure (or a bounded attempt count) so the parties can see why the case died and the provider is not polled indefinitely.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R12: ports.advance throws oracle_attestation_mismatch; three ticks 130 s apart call advance three times, the case stays queued with no error and remains in deal-case-capacity.active.

Expected: state failed with the code and removal from active.

Test R9: provider /submit 402 returns input.pinned with one extra key fromBlockHash and an otherwise valid quote; provider.quote() called three times rejects with invalid_shape each time, /requests/quote and /submit are each called 3 times, imd-orders[key].quote===null, no imd-offer-index row.
7.lowvalidateOraclePrepared normalizes a provider-supplied allowAmbiguous:null to false and accepts itsrc/deals/decision.mjs:11
```
 requireThat(canonical({...value.request,allowAmbiguous:value.request?.allowAmbiguous??false})===canonical({...expected,allowAmbiguous:false})&&value.pinned.fromBlock===expected.window.fromBlock&&value.pinned.toBlock===expected.window.toBlock&&/^0x[0-9a-f]{64}$/i.test(value.pinned.toBlockHash??'')&&/^0x[0-9a-f]{64}$/i.test(value.questionHash??''),'oracle_prepared_input_mismatch');return value;
```
The comment says only the documented false default is normalized, but the nullish-coalescing operator also maps an explicit null to false. The provider inputHash is computed over the wrapper as returned (with null), so quote.inputHash===hash(preparedInput) still passes and the worker proceeds to reserve, sign and pay for a request whose allowAmbiguous holds a value this code never chose and whose provider-side meaning the unpaid probe did not verify.

The stated design is to reject any changed allowAmbiguous.

Fix: const a=value.request?.allowAmbiguous; requireThat(a===undefined||a===false,"oracle_prepared_input_mismatch") before the canonical comparison.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R8: expected=oracleInput(case); value={request:{...expected,allowAmbiguous:null},pinned:{fromBlock,toBlock,toBlockHash:<32-byte hex>},questionHash:<32-byte hex>}. validateOraclePrepared(value,expected) returns value with request.allowAmbiguous===null.

Expected: throws oracle_prepared_input_mismatch, as it does for true and for the string "false".
8.lowSeparate-worker deployment config does not exclude the public API functions, so gateway/compile/workflows handlers are deployed into the process that holds the payment and arbiter keysdeploy/deals.vercel.json:2
```
  "functions": {
```
docs/paid-deals.md says the private host receives the funded IMD payer key, the unfunded resolution signer and the sealing key, and that the public API never receives either signing key. Vercel deploys every file under api/ as a serverless function regardless of the functions map, and .vercelignore excludes only node_modules, .git, test, contracts, public, sqlite and env files.

A deployment of this repository with deploy/deals.vercel.json as its vercel.json therefore also serves /api/gateway, /api/compile, /api/workflows, /api/domains and /api/workers from the same project whose environment contains CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY, and /api/compile and /api/workflows run there against the shared database when the second project also sets CRON_SECRET.

Those handlers do not read the keys today, so there is no direct leak, but the stated isolation boundary (keys only in a process that runs the worker) is not what the configuration produces. Nothing in the repository selects the deploy file either: the root vercel.json schedules /api/compile and /api/workflows only, so a worker project created without a --local-config step never ticks arbitration (safe but silent: deal_worker_unavailable forever).

This could not be executed here; it follows from Vercel api/ auto-detection and the absence of any exclusion.

Fix: add a worker-specific ignore or move api/deals.mjs into its own minimal project root so only the deals function is built in the key-holding deployment, and record in the operator docs how the deals config is selected.
Configuration inspection, not executed (no deployment).

State: a Vercel project created from this repository with deploy/deals.vercel.json copied to vercel.json and the deal keys in env.

Input: GET https:///api/gateway?__claus_route=/v1/health.

Expected: 404, only /api/deals exists in the key-holding deployment.

Actual per Vercel function detection: the public gateway handler is built and executes inside the deployment whose environment contains CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY; ls api shows six handlers and .vercelignore excludes none of them.
9.infoAttested request window is bound by whole-object canonical equality, an assumption about an unprobed provider response that fails only after paymentadapters/deal-oracle-proof.mjs:12
```
 validateOraclePrepared(preparedInput,expected);requireThat(q?.questionHash===preparedInput.questionHash&&canonical(q?.window)===canonical(preparedInput.pinned),'oracle_prepared_input_mismatch');
```
The new binding compares canonical(q.window) with canonical(preparedInput.pinned), i.e. exactly {fromBlock,toBlock,toBlockHash}. The 402 challenge input format was confirmed by the unpaid probe, but the attested request object returned by GET /oracle/requests/{id} was not (no panel was opened), and the previous code only read the three fields from it.

If the attested window carries one more key (fromBlockHash, pinnedAt, chainId), verifyDealOracle throws oracle_prepared_input_mismatch after the IMD payment has been made and settled, which the finding at src/deals/arbitration.mjs:46 shows is then retried every minute until the dispute window closes: panel fee spent, no decision. Retained assumption rather than a demonstrated mismatch.

Fix: bind the three pinned fields individually (q.window.fromBlock, toBlock, toBlockHash each === preparedInput.pinned.*), which is what the attestation message already pins.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R10: a valid attested request/attestation pair (passes verifyDealOracle with workerAmount "600") with request.window changed to {fromBlock:96,toBlock:97,toBlockHash:,fromBlockHash:<32-byte hex>}; attestation unchanged and still matching all pinned fields and preparedInput.

Expected: accepted, since the three pinned fields equal the stored prepared input and the attestation blockHash.

Actual: rejects with oracle_prepared_input_mismatch.
10.infoSigner re-validates with the 3600 s admission margin, so the 60 s resolution_expired check is unreachable and the effective processing window ends an hour before expirysrc/deals/decision.mjs:33
```
 requireThat(/^[1-9][0-9]*$/.test(pin.maximumDealWei??'')&&pin.maximumDealWei===o.maximumDealWei&&d.state===4&&/^0x[0-9a-fA-F]{40}$/.test(d.buyer)&&/^0x[0-9a-fA-F]{40}$/.test(d.worker)&&d.buyer.toLowerCase()!==d.worker.toLowerCase()&&![d.buyer.toLowerCase(),d.worker.toLowerCase()].includes(pin.arbiter.toLowerCase())&&/^[1-9][0-9]*$/.test(d.amount)&&BigInt(d.amount)<=BigInt(pin.maximumDealWei)&&/^(0|[1-9][0-9]*)$/.test(p.workerAmount)&&BigInt(p.workerAmount)<=BigInt(d.amount)&&Number.isSafeInteger(p.expiresAt)&&p.expiresAt>Math.floor(now/1000)+3600&&p.expiresAt<=Number(d.resolutionDue),'network_review_invalid_input');
```
validateDealDecisionShape requires proposal.expiresAt > now+3600 and runtime/arbitration-ports.mjs:38 re-runs it on every tick, including the tick whose only remaining work is to read an already completed native approval and sign. The native host itself only requires authorizationActive (expiresAt > now) and the escrow accepts resolve until expiresAt.

So for any case whose approval lands in the window (expiresAt-3600, expiresAt-60] the worker throws network_review_invalid_input, retries each minute and is finally blocked as deal_not_reviewable; the paid panel result and the Claus approval are discarded. The dedicated signing-time check resolution_expired at arbitration-ports.mjs:51 can never fire.

This is consistent with docs/deal-audit-response.md ("existing processing retains its one-hour margin") and with observed() using processingRemainingSeconds=3600 in tick, so it is recorded as a documented limit with dead code rather than a defect; note that proposal.expiresAt=min(resolutionDue,attestation.expiresAt), so the window can also close an hour before the attestation expiry.

If signing with less than an hour left is intended, separate the admission margin from the signing margin.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R11: native input built exactly as test/deal-arbitration.test.mjs does (valid attestation, pins, proposal.expiresAt=min(resolutionDue,attestation.expiresAt)); validateDealDecisionShape(native,pins,now) passes; the same call with now=(proposal.expiresAt-3540)*1000 (59 minutes before expiry, when the contract would still accept the resolution) throws network_review_invalid_input.
11.infoPer-owner subsidy limits are keyed by requesting principal, not by onchain party address, so one provider address can occupy every subsidized casesrc/deals/arbitration.mjs:31
```
    const day=Math.floor(now()/86400000);for(const [k,limit]of [[projectId+':'+day,ARBITRATION_LIMITS.projectDaily],['principal:'+project.ownerId+':'+day,ARBITRATION_LIMITS.principalDaily],['principal:'+project.ownerId+':total',ARBITRATION_LIMITS.principalTotal],['global:'+day,ARBITRATION_LIMITS.globalDaily]]){const r=await tx.read('deal-case-daily',k);requireThat((r?.value.count??0)<limit,'deal_arbitration_capacity');await tx.write('deal-case-daily',k,{count:(r?.value.count??0)+1},r?.revision??0);}
```
Retained assumption acknowledged in docs/deal-audit-response.md, recorded with the concrete bound. Limits are keyed on projectId and project.ownerId (the principal of the signing address); the party check only requires the owner address to be buyer or worker.

A single provider address W can be the worker in deals with buyers B1..B4 (four sign-ins, four principals, four projects); each buyer requests one case per UTC day, so four cases on day 1 and four on day 2 exhaust cases:8 with W in every case, at a cost of four escrows of 0.0001 ETH plus gas, while the network pays up to 0.5 IMD plus inference per case.

An additional counter keyed on each onchain party address (e.g. two lifetime cases per address) would raise the attacker cost to eight distinct addresses without changing the economic rules.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R13: two principals (owner and bob) each owning a project, each the buyer of a distinct deal that shares worker address W.

Both request() calls return queued and deal-case-capacity.total===2; no per-address counter rejects the second.

Extending to four principals per day over two days reaches total 8 with W in every case.

Review complete. The findings file is written and valid, and no tracked files were changed.

What I reviewed. The delta from 935c323 to be5069c across the arbitration core, the arbitration signing ports, the IMD oracle and payment adapters, the shared decision validator, the evidence bundle, the native reference snapshots, the worker entry point and the new deployment file. I ran the existing deal test suites in a dependency-installed copy under /tmp (12 pass) and wrote three scratch reproductions there, all of which pass on the current code and demonstrate the defects.

Findings recorded in .imd-findings.json

High. A transient store read failure becomes a permanent block. The permitted helper in src/deals/arbitration.mjs swallows every error as false, and this commit added authority_closed to the permanent-block list. That check runs before quote, prepare, submit and around signing. One failed read of the capability record kills the deal's only case forever, after the oracle fee may already be spent. Reproduced with a store proxy that fails one read.

Medium. Fresh-health admission trusts a heartbeat from a worker whose own enable flag is off. The worker writes the heartbeat unconditionally, so the public API keeps admitting cases that the worker blocks on first tick. Each one burns a subsidy slot, the owner's lifetime allowance and the deal's permanent case ID. Reproduced with two arbitration instances on one store.

Low. Provider wrapper drift loops forever. A prepared input with one extra key fails validation before the quote is persisted, so every tick re-quotes and re-probes with no terminal state. The current wire format matches, so this is a stability assumption.

Low. Documentation mismatch. The published operation text says operator suspension stops an admitted case, but admin project suspension does not; only the capability record does. The repository's own test asserts the continuation.

Low. Worker deployment isolation. The deals deployment config does not exclude the other api functions, so the public gateway code is deployed into the key-holding project. Flagged as an unverified deployment-shape assumption.

Boundaries verified without defects. Durable admission independent of requester sessions, original-party ownership and per-owner, per-project, daily and minimum-value limits, the three-hour admission versus one-hour processing margins, explicit unavailable and wrong-kind buyer objections in both the bundle and the validator, the database-fenced release that cancels only signing, signing-unknown and prepared payments while keeping submitting, submitted, unknown and paid states, the mandatory chain-matched maximum pin, the prepared-input binding of request, pinned window, question hash and allowAmbiguous in quote, challenge and proof, the canonical block hash check before any reservation or payment, and the native result bindings before signing.

Remaining assumptions. The provider's inputHash canonicalization matches this repository's digest, cron invocations do not overlap beyond the lease window, and the native host's pins equal the worker's. Financial activation stays disabled and nothing here deploys, transacts or grants anything.

highAny transient failure inside permitted()/stillAllowed() is converted into a permanent authority_closed block of a paid casesrc/deals/arbitration.mjs:21
permitted() wraps the store read of network-capabilities/deal-arbitration in a catch-all that returns false, and this commit added 'authority_closed' to the permanent-block list at src/deals/arbitration.mjs:46. stillAllowed() (= permitted) is evaluated before quote, before prepare, before submit and three times around signing in runtime/arbitration-ports.mjs.

So one transient database/network error (ECONNRESET, Neon websocket drop, statement timeout) on that single read at any of those boundaries throws authority_closed, which tick() now saves as state:'blocked', removes from active, and never retries. The operator capability is still enabled with the unchanged generation, so no authority was actually closed.

Because one permanent case ID exists per deal, the agreement loses its only subsidized review forever; if the IMD oracle fee was already paid (states after submit), that spend is also lost, and the per-owner lifetime allowance and global 8-case subsidy slot are consumed. Before this commit authority_closed inside advance was a retryable error.

Expected: only a real generation change or enabled:false in the admission record should block permanently; a read error should leave the lease released and the case retried on the next tick.

Fix: let permitted() propagate (or return a distinct 'unknown' value for) read failures and treat only an actually observed generation/enabled mismatch as authority_closed; keep infrastructure errors non-permanent.
State: case admitted, capability {enabled:true,generation:1} unchanged. During advance, the first store.read('network-capabilities','deal-arbitration') rejects once with ECONNRESET and succeeds on every later call. Expected: case stays in its current state and is retried next tick. Actual: deal-cases[id].state==='blocked', error==='authority_closed', case removed from deal-case-capacity.active; a second tick does not resume it.

mediumFresh-health admission accepts a heartbeat from a worker whose own CLAUS_DEAL_ARBITRATION_ENABLED flag is off, which then permanently blocks every admitted casesrc/deals/arbitration.mjs:30
The public API and the signer worker are separate deployments with separate env (api/gateway.mjs vs api/deals.mjs). Admission only checks that worker-health/deals.observedAt is within five minutes. api/deals.mjs:21 writes that heartbeat unconditionally after reconcile()+tick(), including when its own createArbitration was built with enabled:false (flag unset or not '1').

In that worker, tick() -> permitted() -> admission() throws deal_arbitration_disabled, permitted returns false, and the case is saved as state:'blocked', error:'authority_closed' on its first tick, without ever calling ports.advance. Meanwhile the API's discovery() keeps reporting enabled:true and request() keeps admitting cases, each one consuming one of the 8 lifetime subsidy slots, the owner's principalTotal allowance and the deal's single permanent case ID.

Nothing in the heartbeat carries the worker's enabled state or its arbitration configuration. Expected (docs/paid-deals.md 'Operator deployment'): new admission must be refused when the worker cannot process.

Fix: have the worker record its enabled flag (and ideally its admission generation) in the heartbeat and require enabled===true at admission; and/or make the local-flag-disabled outcome a retryable wait rather than a permanent block.
State: API process createArbitration enabled:true; worker process createArbitration enabled:false; both share the store; worker-health/deals observedAt fresh; capability {enabled:true,generation:1}.

Input: buyer calls deal_review_request for a valid disputed deal.

Expected: request rejected with deal_worker_unavailable (or the case retried until the worker is correctly configured).

Actual: request returns state:'queued'; the worker's first tick marks it blocked/authority_closed with advance never invoked; deal-case-capacity.total===1 and deal-case-daily principal::total===1 remain consumed; a repeat request returns the dead blocked case; discovery() still reports enabled:true.

See test 'REPRO A' in the file quoted in the previous finding (passes on current code).
lowPrepared-input validation failure never persists the quote, so a drifted provider wrapper re-quotes and re-probes every tick with no terminal stateadapters/imd-oracle.mjs:94
quote() only writes {quote,preparedInput} to imd-orders after the unpaid 402 probe passes validateOraclePrepared. That validator uses shape(), which requires exactly the keys {pinned,questionHash,request} and {fromBlock,toBlock,toBlockHash}.

If the provider's wrapper ever carries one extra key (for example a fromBlockHash or a provider version field), or any field drifts, validation throws before the store write, the imd-orders row stays at quote:null, and v.offer is never checkpointed. Each later tick therefore POSTs /requests/quote again with the same requestKey and POSTs the /submit probe again, forever.

The case never reaches the oracle_quote_expired terminal path because that check only runs once an offer exists, so it keeps its active slot, its consumed daily/global/principal counters and the lease cycle indefinitely, with one quote and one probe hitting the provider every minute per case. Rejecting a changed wrapper is correct; the missing piece is a terminal state (or a bounded attempt count) for a provider format mismatch.

The task states a real unpaid quote matched this shape, so this is an assumption about provider stability rather than a present mismatch.

Fix: persist a 'format_mismatch' outcome on the order after validation failure and block the case with a dedicated permanent code, or cap attempts.
Input: provider /submit 402 returns input.pinned={fromBlock:96,toBlock:97,toBlockHash:0x34..,fromBlockHash:0x34..} (one extra key) with an otherwise valid quote. Call provider.quote({projectId:'case',inputHash,quoteId:'deal-oracle:case'}) three times. Expected: a recorded, terminal mismatch after the first attempt. Actual: each call rejects with invalid_shape, /requests/quote and /submit are each called 3 times, imd-orders[key].quote===null, no imd-offer-index row.

lowPublished operation description says network operator suspension stops an admitted case, but admin project suspension does notdocs/openapi.json:727
The same sentence is in interfaces/contract.mjs:22. The only operator action that stops processing is changing the network-capabilities/deal-arbitration record (enabled:false or a new generation), checked by permitted() at src/deals/arbitration.mjs:21.

The operator's admin route project_access_set (PUT /v1/admin/projects/{projectId}/access, src/access/index.mjs:144) marks project-access suspended, yet tick() never reads project-access, so a case keeps paying the oracle, submitting to the native host and signing after the operator suspended the requesting project. test/deal-arbitration.test.mjs:15 explicitly asserts this continuation.

Either the description should say that only deal-arbitration capability changes stop a case, or tick() should consult project-access when the operator suspended the project. As written, an operator who reads the API contract and suspends a project to halt a suspicious review will not halt it.
State: case admitted and queued; operator calls project_access_set {projectId:, suspended:true}.

Expected per the published description: processing stops.

Actual: the next tick() calls ports.advance (test asserts advances()===2 and state !== 'blocked'); only writing network-capabilities/deal-arbitration enabled:false or a new generation blocks the case.
lowSeparate worker deployment config does not exclude the public API functions, so gateway/compile/workflows code is deployed into the process that holds the payment and arbiter keysdeploy/deals.vercel.json:2
docs/paid-deals.md says the private host receives the funded IMD payer key, the unfunded resolution signer and the sealing key, and that the public API never receives either signing key. Vercel deploys every file under api/ as a serverless function regardless of the functions map; .vercelignore excludes only node_modules, .git, test, contracts, public, sqlite and env files.

A deployment of this repository with deploy/deals.vercel.json as vercel.json therefore also serves /api/gateway, /api/compile, /api/workflows, /api/domains and /api/workers from the same project whose env contains CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY.

Those handlers do not read the keys today, so there is no direct leak, but the stated isolation boundary (keys only in a process that runs the worker) is not what the configuration produces; any env-disclosing or SSRF bug in the much larger public gateway would run with the signing keys present. This is a deployment-shape assumption I could not verify against a live deployment.

Fix: add a worker-specific ignore (or move api/deals.mjs to its own minimal project/root) so only the deals function is built in the key-holding deployment, and have the operator record that only that deployment carries the keys.
State: Vercel project created from this repository with deploy/deals.vercel.json copied to vercel.json and the deal keys in env.

Input: GET https:///api/gateway?__claus_route=/v1/health (or /api/compile).

Expected: 404, only /api/deals exists in the key-holding deployment.

Actual: the public gateway handler executes inside the deployment whose environment contains CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY.
Audit economicsAgent #1505found 1 medium, 2 low
Findings file is written and verified against the tree, no tracked file changed, and the focused suites pass. Here is the review.

Outcome. The corrected paid-agreement candidate at be5069c holds up on most of the boundaries the task names. I found one medium and two low defects, all reproduced in test/scratch/review-repro.test.mjs, and recorded them in .imd-findings.json.

Findings

Medium, fresh-health admission does not prove the worker can process. The heartbeat in api/deals.mjs is written whenever the store is reachable and the tick returns. A worker whose process flag is off, or whose pins are empty or malformed, still heartbeats. The public API then admits a case, consumes one of eight lifetime slots and the owner's lifetime allocation, and the next worker tick blocks it with authority_closed. Case ids are permanent, so that deal can never be reviewed again. Reproduced with two arbitration instances on one store.

Low, reconcile only scans eight allocation rows. The loop in runtime/arbitration-ports.mjs lists with a fixed limit and no cursor, and settled or released rows occupy those slots. A ninth expired never-submitted reservation is never released. Latent today because the lifetime cap is eight, but it breaks silently once the cap is raised or a second chain shares the store.

Low, prepared wrapper accepts allowAmbiguous null. The validator in src/deals/decision.mjs normalizes null to false, so a provider wrapper carrying null passes the equality and the inputHash check, and the worker pays for it. The stated design is to reject any changed value.

Boundaries verified without defect

Admitted cases survive requester session expiry, revocation, and project suspension; only the operator generation or enabled flag stops them. The public evidence route reads case storage directly, so a party cannot veto by hiding their project.

Missing or wrong-kind buyer objections are explicitly represented, frozen at admission, and the shared validator accepts only the two explicit statuses. Terms and result still must match.

Minimum value, per-owner daily and lifetime limits, and the three-hour admission versus one-hour processing margins behave as documented and roll back on rejection.

Release touches only payments with no record, cancelled, signing, signing_unknown or prepared state, under the same transaction fence that prepare and submit use. Submitted and unknown states keep their holds.

The pin ceiling is mandatory and checked against the chain value, and the native validator checks the same equality.

The prepared wrapper is bound end to end: quote and challenge both verify the canonical block hash and the provider hash, and proof, native host, and signer consume the same stored wrapper.

Remaining assumptions to carry forward

The attested request and attestation wire shapes were not confirmed by the unpaid probe. If the live read returns a window object with extra keys, every paid case will loop on a prepared-input mismatch after payment.

An expired unpaid quote permanently fails the deal's only case. A nine-minute RPC or provider outage between quote and submit therefore forfeits the subsidy for that deal with no operator reopen path. This is documented, but it is a sharp edge.

The bundle URL hardcodes the public API origin, and the questionHash to question-text link relies on the provider.

No scheduler cancels a native review once its case is blocked, so the native inference spend can still occur for a dead case.

mediumDeal worker heartbeat is written even when the worker cannot process cases, so fresh-health admission burns the deal's single subsidized caseapi/deals.mjs:21
The corrections make new admission depend on a worker heartbeat observed within five minutes (src/deals/arbitration.mjs:16 workerHealth, checked inside request()).

The heartbeat in api/deals.mjs is written whenever the store is reachable and tick() returns, regardless of whether this worker can actually advance cases. tick() returns normally when CLAUS_DEAL_ARBITRATION_ENABLED is not '1' on the worker: permitted() then fails for every active case and each is saved as blocked/authority_closed without ever calling ports.advance.

The same holds when the worker's CLAUS_DEAL_PINS is empty or malformed (dealPorts() returns a stub whose context() throws; tick() catches per case, so the heartbeat is still written). So the health signal the public API relies on does not prove processing capability.

Because a case id is permanent per escrow/chain/deal and request() returns the existing (blocked) case forever, every admission under this condition consumes one of the eight lifetime cases and the per-owner lifetime allocation, and permanently forecloses arbitration for that deal; the counters are never refunded. docs/deal-audit-response.md says both the admission record and the process flag must be enabled, but nothing ties the heartbeat to that flag or to the worker's pin configuration.

Fix: include enabled (process flag) and the configured chain ids in the heartbeat and require them in workerHealth(), or skip the heartbeat write when the flag is off / pins are invalid.
State: public API process has CLAUS_DEAL_ARBITRATION_ENABLED=1 and network-capabilities/deal-arbitration {enabled:true,generation:1}; the worker process runs api/deals.mjs with the flag unset (or with CLAUS_DEAL_PINS=[]).

Worker cron runs: tick() returns {processed:0}; worker-health/deals.observedAt=now is written.

discovery() reports enabled:true; a party calls deal_review_request for a disputed deal: case queued, deal-case-capacity.total becomes 1, principal counters incremented.

Next worker cron: permitted() -> admission() throws deal_arbitration_disabled -> case saved state=blocked, error=authority_closed; advance never called.

deal_review_request again returns the blocked case; total stays 1.

Expected: step 2 rejected with deal_worker_unavailable, or the blocked case should not consume the lifetime allocation.

Actual: the subsidy slot and the deal's only case are lost.

Reproduced in test/scratch/review-repro.test.mjs (F1) with two createArbitration instances on one store: the enabled:false worker tick returns processed:0, the enabled:true API admits, the worker tick blocks with authority_closed, advance count stays 0 and total remains 1.
lowreconcile() reads at most eight allocation rows with no cursor, so later reservations are never released or settledruntime/arbitration-ports.mjs:58
store.list returns rows ordered by id with limit 8 and no 'after' cursor, and the loop never pages. Rows already settled or released still occupy those eight slots. Any allocation whose id sorts after the first eight rows is never visited: an expired never-submitted reservation is never released (the hold stays reserved forever) and a submitted payment is never reconciled or cost-settled from this path.

Today the lifetime cap of eight cases keeps the collection at eight rows, so the bound is latent, but it silently breaks as soon as the cap is raised, a second chain pin shares the store, or any case produces a second offer row.

Fix: page with the after cursor until fewer than limit rows return, or iterate only billing=reserved rows.
State: nine deal-oracle-allocations rows offer-1..offer-9, all billing:reserved with offer.expiresAt in the past and caseId pointing at no case (so releaseUnsent should release each); 9000 units funded and 9x1000 reserved.

Call ports.reconcile() five times.

Expected: all nine released, balance reserved=0.

Actual: offer-1..offer-8 become released-unsent, offer-9 stays reserved and the balance stays reserved:1000 after any number of runs.

Reproduced in test/scratch/review-repro.test.mjs (F2).
lowvalidateOraclePrepared normalizes a provider-supplied allowAmbiguous:null to false and accepts itsrc/deals/decision.mjs:11
The comment says only the documented false default is normalized, but the nullish-coalescing operator also maps an explicit null to false. The provider's inputHash is computed over the wrapper as returned (with null), so quote.inputHash===hash(preparedInput) still passes and the worker proceeds to reserve, sign and pay for a request whose allowAmbiguous field holds a value this code never chose and whose provider-side meaning is unverified by the unpaid format probe.

The stated design is to reject any changed allowAmbiguous; only an absent key or literal false should normalize.

Fix: const a=value.request?.allowAmbiguous; requireThat(a===undefined||a===false,'oracle_prepared_input_mismatch') before the canonical comparison.
Input: expected=oracleInput(case); value={request:{...expected,allowAmbiguous:null},pinned:{fromBlock:expected.window.fromBlock,toBlock:expected.window.toBlock,toBlockHash:<32-byte hex>},questionHash:<32-byte hex>}. validateOraclePrepared(value,expected) returns value.

Expected: throws oracle_prepared_input_mismatch, as it does for true or the string 'false'.

Audit mathAgent #293found 4 low, 1 info
Findings file is written and valid, the working tree is clean, and all scratch material lives only in /tmp. Here is the recap.

Outcome. I reviewed the delta from 935c323 to be5069c against the audit response, traced the corrected offchain financial paths end to end (admission, subsidy limits, evidence bundle, prepared-input binding, payment release, oracle proof, shared validator, native snapshot, signer boundary), confirmed the native snapshot hashes match source.json, ran the existing arbitration and payment suites (11 pass), and wrote focused reproductions in a scratch copy. Five findings are recorded in .imd-findings.json: four low, one info. No critical or high defect was found, so no Foundry proof was needed. The Solidity is unchanged and was not re-audited.

Findings.

Unfenced release race (low). releaseUnsent runs without the case lease and cancels a prepared payment at 60 seconds before quote expiry, while the payment module still accepts submission until 20 seconds before expiry. Overlapping cron invocations can cancel a payment that an in-flight advance has already decided to submit. The case then blocks with the wrong label authority_closed. Funds stay safe. Reproduced.

Disabled worker still heartbeats (low). A signer deployment without the enable flag blocks every admitted case and then writes a fresh heartbeat. The public API keeps admitting, and each blocked case permanently consumes one of the eight subsidy slots. Reproduced.

Over-strict window binding (low). The oracle proof now compares the attested request window to the prepared input by whole-object equality. The unpaid probe confirmed the challenge format, not the attested request format. One extra key there makes a paid case retry every minute until the deal window closes, with the panel fee spent. Reproduced.

Signer host serves the public gateway (low). The deals Vercel config does not exclude the other handlers under api/, so the private deployment also exposes the gateway with database writes. Not executed, since there is no deployment, but it follows from Vercel's auto-detection.

Owner limit keyed by principal (info). Retained assumption, acknowledged in the audit response, with the concrete bound: one provider address can sit in all eight cases via four buyer principals over two UTC days.

Verified as correct. Durable admission independent of requester sessions; operator generation revocation; explicit unavailable and wrong-kind dispute handling in both the bundle and the shared validator; the minimum value and daily and total counters in one transaction; the three-hour admission versus one-hour processing margins; cancellation limited to signing, signing-unknown and prepared states with submitted and unknown states retained; the mandatory decimal pin equality on both the chain port and the validator; the prepared-input hash binding, canonical block check, and the same stored prepared input reaching proof and native host.

Remaining assumptions. The attested request wire format, the provider's inputHash construction as sha256 over sorted canonical JSON, and the IMD order idempotency by requestKey are unverified without a paid panel.

lowreleaseUnsent is not fenced by the case lease and cancels payments that are still submittable, so overlapping worker runs can kill a live caseruntime/arbitration-ports.mjs:18
reconcile() runs releaseUnsent for every reserved allocation before tick() and without taking the case lease. It cancels a prepared payment as soon as offer.expiresAt<=now()+60000, while the payment module itself still accepts submit until deadline>now+15 (deadline<=quote.expiresAt-5, i.e. up to 20s before expiry) and advance() in another invocation may already have passed its own expiresAt>now()+60000 check (line 29) and be between payment.prepare and payment.submit.

With the minute cron and a 300s maxDuration, invocations overlap.

Invocation A: line 29 check passes at T (expiresAt=T+61s), prepare completes at T+3s.

Invocation B: reconcile at any point in T+1s..T+41s sees expiresAt<=now+60s, abandonUnsent cancels the prepared record and settleReservation releases the hold.

A: submit() -> update(offerId,'prepared') throws payment_state_conflict (non-permanent).

Next tick: state.state==='cancelled' -> requireThat fails with authority_closed (also a wrong label: nothing closed authority) -> permanent blocked, subsidy slot consumed, no replacement purchase. Money is safe (the submit fence holds), but a case that was about to be paid dies and is mislabelled.

Minimal fix: only release when nothing can be submitted any more, i.e. when a.offer.expiresAt<=now() (submit is impossible after expiresAt-20s), and/or skip allocations whose case holds an unexpired lease; report expiry-driven cancellation as oracle_quote_expired rather than authority_closed.
State: case queued and allowed; deal-oracle-allocations[live]={billing:'reserved', offer:{expiresAt:now+50000}}; imd-payments[live]={state:'prepared', deadline:now_s+40}.

Call ports.reconcile().

Expected: nothing cancelled, since the case is allowed, the quote has 50s left and submit would still accept (deadline > now+15).

Actual: imd-payments[live].state==='cancelled', allocation billing==='released-unsent' while deal-cases state is still 'queued'; a subsequent advance() blocks the case with authority_closed.

Reproduced with a node test (R1) in a scratch copy of the tree: output 'payment cancelled allocation released-unsent case queued quote remaining ms 50000'.
lowA worker running with CLAUS_DEAL_ARBITRATION_ENABLED unset still writes a fresh heartbeat, so admission stays open while every admitted case is blocked and the subsidy is burnedsrc/deals/arbitration.mjs:16
workerHealth only checks observedAt freshness. api/deals.mjs (line 20-21) builds createArbitration with enabled:process.env.CLAUS_DEAL_ARBITRATION_ENABLED==='1' and writes worker-health/deals after tick() regardless of that flag.

With the flag unset on the private signer deployment (two separate deployments carry two separate copies of the flag), tick() evaluates permitted(v) -> admission() -> requireThat(enabled&&...) throws -> every active case is saved as blocked/authority_closed, and the heartbeat is then written.

The public API (its own flag set) sees worker.healthy===true, discovery.enabled===true, and request() keeps admitting; each admission increments deal-case-capacity.total, which is never decremented for blocked cases. The eight-case subsidy can be consumed by configuration drift alone, and the docs/paid-deals.md claim that new admission rejects an unhealthy worker is weaker than stated: an active but disabled worker counts as healthy.

Fix: include the worker's effective authority in the heartbeat (enabled flag, pins hash, admission generation) and require it in workerHealth, or do not run tick()/write the heartbeat when the flag is off.
State: network-capabilities/deal-arbitration enabled (generation 1), API createArbitration({enabled:true}), worker createArbitration({enabled:false}) on the same store.

Steps: API request() admits case A (queued); worker tick(), then heartbeat write (same order as api/deals.mjs).

Expected: discovery.enabled false and further request() rejected with deal_worker_unavailable, or case A untouched.

Actual: case A state 'blocked', error 'authority_closed'; discovery.enabled true, remainingCases 7; a second deal is admitted (queued) and blocked on the next worker tick; deal-case-capacity.total===2.

Reproduced with a node test (R2) in a scratch copy of the tree.
lowAttested request window is bound by whole-object canonical equality, so any extra provider field makes a paid case retry forever instead of resolvingadapters/deal-oracle-proof.mjs:12
The new binding compares canonical(q.window) with canonical(preparedInput.pinned) (exactly {fromBlock,toBlock,toBlockHash} after shape()). The 402 challenge input format was confirmed by the unpaid probe, but the attested request object returned by GET /oracle/requests/{id} was not (no panel was opened), and the previous code only read window.fromBlock/toBlock/toBlockHash from it.

If the attested request window carries one more key (fromBlockHash, pinnedAt, chainId, ...), verifyDealOracle throws oracle_prepared_input_mismatch after the IMD payment has been made and settled. That error is not in the permanent list of tick() (src/deals/arbitration.mjs line 46), the oracle checkpoint leaves state 'oracle-pending', and every minute the case re-reads the chain, re-verifies and throws again until resolutionDue-3600 passes and deal_not_reviewable blocks it.

Outcome: panel fee spent, no decision, nothing visible in the public case.

Fix: bind the three pinned fields individually (q.window.fromBlock, toBlock, toBlockHash each === preparedInput.pinned.*), which is what the attestation message already pins, or at least add post-payment verification failures to the permanent list so the failure becomes visible.
Input: a valid attested request/attestation pair (passes verifyDealOracle with workerAmount '600') with request.window changed to {fromBlock:96,toBlock:97,toBlockHash:,fromBlockHash:<any 32-byte hex>}; attestation unchanged and still matching all pinned fields and preparedInput.

Expected: accepted, since fromBlock/toBlock/toBlockHash equal the stored prepared input and the attestation blockHash.

Actual: rejects with oracle_prepared_input_mismatch.

Reproduced with a node test (R3) in a scratch copy of the tree.
lowdeploy/deals.vercel.json deploys every api/*.mjs handler on the signer host, so the public gateway with database writes is also served from the private deploymentdeploy/deals.vercel.json:2
Vercel auto-detects every file under api/ as a serverless function; the functions block only configures api/deals.mjs and nothing excludes api/gateway.mjs, api/compile.mjs, api/workflows.mjs, api/workers.mjs or api/domains.mjs. The signer deployment therefore also exposes https:///api/gateway?__claus_route=/v1/...

(and /mcp handling) using the signer host CLAUS_NETWORK_DATABASE_URL and env (no CLAUS_NETWORK_ORIGIN or rate salt unless copied), i.e. a second, unlisted public API instance with full database write access on the deployment that holds CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY.

The keys are not readable through the gateway code, but the stated boundary in docs/paid-deals.md (a separate private host that receives only its own inputs) does not hold, and public traffic lands on the signer deployment.

Fix: add a .vercelignore for the signer deployment that keeps only api/deals.mjs and its imports, or move the worker entry into its own project directory with its own api/ folder.
State: a Vercel project deployed from this repository with deploy/deals.vercel.json as vercel.json and the signer env.

Input: GET https://.vercel.app/api/gateway?__claus_route=/v1/capabilities (the query form the root rewrites use).

Expected: 404, nothing but the authenticated /api/deals cron handler exists.

Actual: the public gateway answers from the signer host against the shared database.

Not executed here (no deployment); follows from Vercel api/ auto-detection and the absence of any exclusion.
infoPer-owner subsidy limit is keyed by the requesting principal, not by the onchain party addresses, so one provider address can occupy all eight casessrc/deals/arbitration.mjs:31
Retained assumption, acknowledged in docs/deal-audit-response.md, recorded here with the concrete bound. The limits are keyed on projectId and project.ownerId (the usr_ digest of the signing address). The party check only requires the owner address to be buyer or worker.

A single provider address W can be the worker in deals with four buyer addresses B1..B4 (four sign-ins, four principals, four projects); each buyer requests one case per UTC day, so 4 cases on day 1 and 4 on day 2 exhaust cases:8 with W in every case, at a cost of 4 x (0.0001 ETH escrow + gas), while the network pays up to 0.5 IMD plus up to 2 USDC inference per case.

An additional counter keyed on each onchain party address (buyer and worker, e.g. 2 lifetime cases per address) raises the attacker cost to eight distinct addresses and prevents one counterparty from sitting in every subsidised case without changing the economic rules.
State: four principals P1..P4 owning projects X1..X4 whose owner addresses are the buyers of four deals that share worker address W; each deal amount 1e14 wei, state 4, resolutionDue > now+3h, public terms/result.

Day 1: request() from P1..P4 succeeds four times (globalDaily 4).

Day 2: four more deals with the same W succeed. deal-case-capacity.total===8 and discovery.enabled is false for everyone else; no per-address counter rejects any of them.
Audit permissionsAgent #1199found 4 low, 3 info
Review complete. The findings file at the repository root is valid and holds seven entries. The working tree contains nothing else.

Outcome. No critical or high defect was found in the corrected offchain paths. The delta does what the response document claims for the points I could execute: admission survives session expiry and project suspension, the bundle marks a missing or wrong-kind objection explicitly and the validator accepts only that shape, the subsidy minimum and per-owner limits hold, the 3-hour admission margin is enforced, release touches only never-submitted payment states under a database fence, the amount pin is mandatory on both hosts, the prepared-input validator rejected every mutation I tried (amount, question, window, pinned block, consumer, allowAmbiguous true, extra keys, chain, quorum), and the five native snapshots match their recorded hashes. The existing test file passes in a dependency-installed copy under /tmp.

Findings recorded (all reproduced against the code in a /tmp copy):

Low, worker flag not in heartbeat. A worker deployed with the arbitration flag off still writes a fresh heartbeat. The public API admits cases, the worker blocks each as authority_closed within a minute, and the lifetime and per-owner slots stay consumed while discovery reports enabled.

Low, global pause no longer stops the financial worker. Removing the per-tick identity check also removed the only link to the access policy's paused flag. Processing and signing continue during a network-wide pause. The docs do not say this.

Low, wrong failure label on expired quotes. Because reconcile runs before tick, an expired never-submitted quote cancels the payment first, so the case is blocked as authority_closed rather than oracle_quote_expired. The release itself is correct.

Low, signing uses the admission margin. The shape validator's one-hour rule is re-run on every tick, so a completed Claus approval arriving in the last hour is never signed. The 60-second resolution_expired check is unreachable. Effective processing budget after admission is two hours, not three.

Info, deterministic failures are retried forever. Attestation, binding, reorg and native HTTP 400 errors are not in the permanent list, so a stuck case retries each minute with a provider status call until the window closes.

Info, operator pause is terminal. A brief capability disable cancels prepared payments and the case blocks on re-enable even with the same generation.

Info, cron file is not selected by anything. Only the root vercel.json is read by Vercel, so the worker cron exists only if an operator renames the file by hand. The failure mode is safe. A worker project also deploys every public api function alongside the signing keys.

Remaining assumptions I could not verify locally:

The provider's inputHash canonicalisation matches this repository's canonical JSON. A mismatch fails closed with no payment.

Submitted or unknown payment outcomes hold the subsidy permanently. No chain proof of Permit2 non-use is attempted, so dead holds are never recovered.

The native validator cannot check evidence absence. A compromised worker secret could present a real objection as unavailable to Claus while the panel saw it.

Both hosts must hold identical pins and the same arbitration flag. Nothing cross-checks them.

The bundle URL host is hard-coded. A different public origin makes every panel report inability after the subsidy is spent.

Vercel cron overlap is handled by state fences only. The 120-second case lease is shorter than a worst-case advance, which relies on those fences rather than the lease.

lowWorker heartbeat does not carry the worker's own arbitration flag, so a worker deployed with CLAUS_DEAL_ARBITRATION_ENABLED unset passes fresh-health admission and then permanently blocks every admittsrc/deals/arbitration.mjs:16
Fresh-health admission only checks that the separate worker wrote worker-health/deals within five minutes. api/deals.mjs writes that heartbeat after every successful tick() regardless of its own CLAUS_DEAL_ARBITRATION_ENABLED value, and tick() with the flag off still runs permitted(v) which throws deal_arbitration_disabled inside admission() and blocks each active case as authority_closed (terminal, removed from active, counters in deal-case-capacity and deal-case-daily are never returned).

The public API process evaluates its own flag, so a public API with the flag on plus a worker with the flag off (a plausible misconfiguration between the two separate Vercel deployments the docs now require) admits cases, burns one of the eight lifetime slots and the per-owner daily/total slot per request, blocks the case within a minute without spending IMD money, and keeps reporting capabilities.deals.arbitration.enabled=true.

The heartbeat should include the worker's effective enabled flag and generation (or the worker should not heartbeat as healthy when disabled), and admission should require it.
State: network-capabilities/deal-arbitration = {enabled:true,profile:'public-deliverable-v1',generation:1}; worker-health/deals = {observedAt: now}.

Public API side: createArbitration({enabled:true}).request(actor, projectId, 1, dealId) -> state 'queued', deal-case-capacity.total = 1.

Worker side: createArbitration({enabled:false}).tick() then write worker-health observedAt=now (exactly what api/deals.mjs does).

Expected: the public API should refuse admission or the case should remain queued until a correctly configured worker exists.

Actual (run against the /tmp copy with test/apps-fixture.mjs): case state 'blocked', error 'authority_closed', advance never called, deal-case-capacity.total still 1, discovery().enabled still true, and a second request by the same owner that day is refused with deal_arbitration_capacity.
lowNetwork-wide access-policy pause no longer halts arbitration spending or resolution signing after the per-tick identity check was removedsrc/deals/arbitration.mjs:21
At 935c323 permitted() also called identity.allowed(v.actor,'deal.review',...), which returns false when the active access policy has paused:true (writesEnabled in api/deals.mjs and runtime/server.mjs). The correction intentionally removed the requester-session veto but with it removed the only link between the operator's network-wide pause and the financial worker.

Now tick() keeps calling ports.advance (IMD quote, Permit2 signing, payment submission, native review, arbiter signature) while the whole network is paused; only the deal-arbitration capability record and the process flag stop it. docs/paid-deals.md and docs/deal-audit-response.md say 'network operator suspension' still stops processing without saying the global pause is excluded.

If this is intended, document that paused does not cover arbitration; otherwise consult the access policy's paused flag in permitted()/allowed() (it is not a requester-controlled signal, so it does not reintroduce the party veto).
Fixture: admitted case in state 'queued', worker-health fresh, capability enabled.

Owner publishes and activates an access policy with {...config,paused:true}; access_policy_get confirms paused=true.

Call tick().

Expected (behaviour at 935c323 and the documented 'operator suspension stops processing'): case blocked with authority_closed and advance not called.

Actual: advance is called once and the case moves to 'oracle-pending' (observed: 'advances while paused: 1 state: oracle-pending').
lowAn expired never-submitted quote is recorded on the case as authority_closed rather than oracle_quote_expired because reconcile() cancels the payment before tick() evaluates the expiryruntime/arbitration-ports.mjs:29
api/deals.mjs runs ports.reconcile() before deals.tick(). For a reserved allocation whose quote expired without a submit intent, releaseUnsent() cancels the imd-payments row and releases the hold first.

When tick() then reaches advance(), payment.status() is already 'cancelled', so the first requireThat fires and the case is permanently blocked with error:'authority_closed'; the oracle_quote_expired branch and the docs statement 'Expired unpaid quotes fail the original case' are never reflected in the public case record.

The public case therefore reports an operator revocation that did not happen, which is misleading for the parties and for anyone auditing why a subsidized case died. The release itself is correct and atomic.

Fix: check offer.expiresAt before the cancelled check, or have releaseUnsent record the reason on the case, or map a cancelled payment with an expired offer to oracle_quote_expired.
State: case 'oracle-pending' with offer {id:'q1', expiresAt: now-1, maximum:'500'}, allocation q1 billing 'reserved' with the correct inputHash, imd-payments q1 state 'prepared', subsidy balance reserved 500.

Run ports.reconcile() then createArbitration({ports}).tick() (the api/deals.mjs order).

Expected: allocation 'released-unsent' and case blocked with error 'oracle_quote_expired'.

Actual (run in the /tmp copy): allocation 'released-unsent', balance available 1000 / reserved 0, but case state 'blocked' with error 'authority_closed'.
lowSigner re-validates with the admission margin, so a completed Claus approval with less than one hour left is never signed and the resolution_expired check is unreachablesrc/deals/decision.mjs:33
validateDealDecisionShape requires proposal.expiresAt > now+3600. That margin is appropriate when the native host admits a review, but runtime/arbitration-ports.mjs:38 re-runs validateDealDecision(input,pins,now()) on every tick, including the tick whose only remaining work is to read an already completed native approval and sign. The native host itself only requires authorizationActive (expiresAt > now), and the escrow accepts resolve until expiresAt.

So for any case whose approval lands in the window (expiresAt-3600, expiresAt-60], the worker throws network_review_invalid_input (not in the permanent list), retries every minute, and finally blocks with deal_not_reviewable once observed() fails; the paid IMD panel result and the Claus approval are discarded without a signature. The dedicated signing-time check resolution_expired at arbitration-ports.mjs:51 (60 s margin) can never fire.

The effective processing budget after a 3-hour admission is therefore 2 hours, which the response document does not state.

Fix: separate the admission margin from the signing margin (pass the margin into the shape validator, or skip the 3600 s clause when a completed native result is being bound) and make the real signing bound the 60 s check.
Build the native input exactly as test/deal-arbitration.test.mjs does (valid attestation, pins, proposal.expiresAt = min(resolutionDue, attestation.expiresAt)). validateDealDecisionShape(native,pins,now) passes.

Call it again with now = (proposal.expiresAt-3540)*1000, i.e. 59 minutes before expiry when the contract would still accept the resolution.

Expected: the already-approved proposal is bound and signed (only resolution_expired at 60 s should stop it).

Actual: throws network_review_invalid_input; in tick() this is non-permanent, the case loops each minute and is blocked as deal_not_reviewable when resolutionDue-3600 passes (reproduced in the /tmp copy as REPRO 7).
infoDeterministic oracle/native verification failures are not terminal: the case is retried every minute, with a provider status call per retry, until the dispute window closessrc/deals/arbitration.mjs:46
Only six error codes are permanent.

Errors that depend solely on already-checkpointed state are retried indefinitely: oracle_prepared_input_mismatch, oracle_question_mismatch, oracle_attestation_mismatch, oracle_signature_invalid, oracle_amount_invalid (all raised by verifyDealOracle on the stored v.oracle), case_binding_mismatch, oracle_admission_mismatch, native_binding_mismatch, deal_observation_reorg, and a native host 400/403 (native() maps every non-ok, non-404, non-429 status to native_review_unavailable).

Each retry runs payment.reconcile (an authenticated IMD /requests/{id} GET) and, for native rejections, a fresh POST of the ~100-200 KB input. For a disputed deal that is 3 days long this is roughly 4,000 provider calls per stuck case; the case also keeps its active slot, so tick() spends part of its 300 s budget on it every minute.

No money is spent twice, but a stored attestation that fails verification will never pass and a native network_review_invalid_input for an unchanged input will never succeed, so these should be recorded as failed with the code, as the oracle disagreed/refused/failed states already are.
State: case with checkpointed offer, settled allocation, imd-payments state provider_paid with outcome.admission.result={kind:"oracle",requestId}, and checkpointed oracle whose attestation.message.expiresAt-issuedAt is 86399 (or signature by a non-IMD key).

Each tick: observed() ok -> advance -> verifyDealOracle throws oracle_attestation_mismatch -> catch: permanent=false -> state unchanged, lease cleared.

Expected: state failed with error oracle_attestation_mismatch and removal from active.

Actual: identical retry every minute, including provider.status() network calls, until resolutionDue-3600 when deal_not_reviewable blocks the case.

The same path applies to a native host that answers HTTP 400 network_review_invalid_input to the POST.
infoA temporary operator disable of the deal-arbitration capability cancels prepared (signed, unsent) payments and permanently kills in-flight cases on re-enableruntime/arbitration-ports.mjs:18
releaseUnsent releases whenever allowed(caseId) is false, which includes network-capabilities/deal-arbitration.enabled=false with the same generation. The reconcile() pass therefore cancels any payment in signing, signing_unknown or prepared state while the capability is off, even for one minute.

When the operator re-enables with the same generation, permitted() is true again, advance() runs, payment.status() returns cancelled and the case is blocked with authority_closed; the lifetime slot stays consumed, and the parties see an authority revocation even though the operator only paused briefly. The release itself is correct and database-fenced.

This is a design consequence worth stating explicitly in docs/paid-deals.md (operator pause is terminal for admitted cases) or, if a pause should be resumable, releasing only when the case is terminal or the offer has actually expired.
State: admitted case oracle-pending with offer q1 expiring in 500 s, allocation q1 reserved (500), imd-payments q1 state prepared.

Operator sets deal-arbitration.enabled=false (generation unchanged) and the cron runs ports.reconcile().

Observed in the /tmp copy: imd-payments q1 -> cancelled, allocation -> released-unsent.

Operator sets enabled=true; next tick(): advance() hits requireThat(state.state!=='cancelled','authority_closed') and the case is blocked permanently.

Expected per docs: a pause that does not bump generation should not terminate the case, or the docs should say it does.
infoSeparate-worker cron exists only as deploy/deals.vercel.json; nothing selects it, and a worker deployment also ships every public api/*.mjs functiondeploy/deals.vercel.json:6
The private worker is configured correctly in content (authenticated GET /api/deals every minute, 300 s limit, heartbeat written after reconcile+tick). But Vercel reads only the repository-root vercel.json, which schedules /api/compile and /api/workflows and not /api/deals.

There is no script, branch, or build step that installs deploy/deals.vercel.json as vercel.json, so a second Vercel project pointed at this repo gets the public API crons and never ticks arbitration; the failure mode is safe (no heartbeat, deal_worker_unavailable on request, discovery enabled=false) but silent.

Conversely, a project that does use the deals file still deploys api/gateway.mjs, api/compile.mjs, api/workflows.mjs, api/domains.mjs and api/workers.mjs as functions in the same environment that holds CLAUS_DEAL_PAYMENT_KEY, CLAUS_DEAL_ARBITER_KEY and CLAUS_DEAL_SEALING_KEY; with no rewrites, /api/gateway is still directly reachable unless the project uses deployment protection.

None of those handlers read the keys, so this is an attack-surface and operations assumption, not a demonstrated leak.
Deploy the repository unchanged to a Vercel project intended as the deals worker, with CLAUS_DEAL_ARBITRATION_ENABLED=1 on both projects.

Expected: /api/deals is invoked every minute and worker-health/deals is refreshed.

Actual: root vercel.json applies, /api/deals is never scheduled, worker-health/deals is never written, deal_review_request returns 503 deal_worker_unavailable and capabilities.deals.arbitration.enabled is false.

With the file copied to vercel.json, vercel ls/the deployment functions tab shows all six api/*.mjs functions live in the worker project.
Audit judgeAgent #715found 1 high, 2 medium, 5 low, 3 info
The findings file is written and every snippet was verified against the tree. Final recap.

Outcome. I judged the 20 specialist findings against commit be5069c, reproduced each claim with a node test file under test/scratch/judge-repro.test.mjs, merged duplicates, and wrote 11 findings to .imd-findings.json. All 13 reproduction tests pass on the current code, which confirms the defects they describe. The existing eight-test arbitration suite still passes, and no repository file outside test/scratch and the findings file was touched.

Findings kept, by severity

High. A single transient store read error inside the admission check is turned into a permanent authority_closed block. The catch-all in permitted() returns false, and this commit made authority_closed permanent, so one dropped Neon connection kills a case, including after the IMD fee was paid. Reproduced with a Proxy store that fails one read.

Medium. The worker heartbeat is written even when the worker cannot process. A worker with its own arbitration flag off still heartbeats, the public API keeps admitting, and every admitted case is blocked on its first tick with the subsidy slots and the deal's only case ID consumed. Four specialists reported this; merged into one.

Medium. releaseUnsent cancels prepared payments that submit would still accept, and also under a temporary operator pause with unchanged generation. advance() then reports authority_closed, so expired quotes are mislabelled and a brief pause permanently kills in-flight cases. Three specialist findings merged.

Low. The global access-policy pause no longer stops the worker, since the identity check was removed with the requester veto, and project suspension never did, while the published description says operator suspension stops a case.

Low. reconcile() lists eight rows with no cursor, so a ninth reservation is never released.

Low. Deterministic verification failures and a provider-format mismatch at quote time are retried every minute with provider calls and never reach a terminal state.

Low. The prepared-input validator accepts an explicit allowAmbiguous of null.

Low. The separate-worker Vercel config does not exclude the public API handlers from the key-holding deployment, and nothing in the repo selects that config. Not executed; stated as configuration inspection.

Info. Whole-object window equality in the oracle proof is an assumption about the unprobed attested-request format. The one-hour margin is re-applied at signing so the 60-second check is dead code, consistent with the docs. Per-owner limits are keyed by principal rather than onchain address, as the response document acknowledges.

Dropped or downgraded. Nothing was dropped outright; each specialist claim reproduced. The signing-margin and window-equality items were downgraded to info because the documented one-hour processing margin and the unverified wire format make them assumptions rather than defects.

Remaining assumptions for the requester. The real attested-request wire format, the Vercel deployment shape, and the provider's handling of a null allowAmbiguous were not observable here. Financial activation remains disabled, and no deployment or transaction was made.

highAny transient failure inside permitted()/stillAllowed() is converted into a permanent authority_closed block of a possibly paid casesrc/deals/arbitration.mjs:21
permitted() wraps the store read of network-capabilities/deal-arbitration in a catch-all that returns false. tick() treats false as authority_closed and saves the case as state blocked (line 41), and this commit also added authority_closed to the permanent-error list (line 46), so the same catch-all now governs every stillAllowed() call inside advance(): before quote, before prepare, before submit and three times around signing.

One transient database error on that single read (Neon websocket drop, ECONNRESET, statement timeout) therefore permanently blocks the case, removes it from the active list and never retries it, although the operator capability is still enabled with the unchanged generation.

One permanent case ID exists per deal, so the agreement loses its only subsidized review; when the failure happens after submit the IMD oracle fee already paid is lost too, and the per-owner lifetime allowance and global eight-case slot stay consumed. At 935c323 a throw from inside advance was retryable.

Fix: let read failures propagate (or return a distinct unknown value) from permitted(), and reserve authority_closed for an actually observed generation change or enabled:false in the admission record; keep infrastructure errors non-permanent.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R2: case admitted, capability {enabled:true,generation:1} unchanged; the store passed to createArbitration is a Proxy whose read of network-capabilities rejects exactly once (asserted failed===1) and succeeds afterwards.

Expected: case stays queued and is retried next tick.

Actual: deal-cases[id].state==="blocked", error==="authority_closed", the id is removed from deal-case-capacity.active, ports.advance is never called and a second tick does not resume it.

The second half of R2 injects the same single failure during stillAllowed() inside advance and gets the same permanent block.
mediumDeal worker heartbeat is written even when the worker cannot process cases, so fresh-health admission keeps admitting and every admitted case is burnedapi/deals.mjs:21
The public API and the signer worker are separate deployments with separate copies of CLAUS_DEAL_ARBITRATION_ENABLED and CLAUS_DEAL_PINS.

Admission only requires worker-health/deals.observedAt within five minutes (src/deals/arbitration.mjs:16,30). api/deals.mjs writes that heartbeat unconditionally after reconcile()+tick(), including when its own createArbitration was built with enabled:false (flag unset or not "1") or when dealPorts() fell back to its stub because the pins are invalid.

With the flag off, tick() -> permitted() -> admission() throws deal_arbitration_disabled, permitted returns false and every active case is saved as blocked/authority_closed on its first tick without ever calling ports.advance.

Meanwhile the public API keeps reporting capabilities.deals.arbitration.enabled=true and request() keeps admitting; each admission consumes one of the eight lifetime subsidy slots, the owner daily/total allowance and the deal's single permanent case ID, none of which is refunded. docs/paid-deals.md says new admission rejects a worker that cannot process, but nothing in the heartbeat carries the worker's enabled flag, pin configuration or admission generation.

Fix: record the worker's effective enabled flag (and ideally the generation it is serving) in the heartbeat and require enabled===true in workerHealth(); or skip the heartbeat when the flag is off or the pins are invalid.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R1: two createArbitration instances on one store; the API side has enabled:true, the worker side enabled:false, capability {enabled:true,generation:1}.

Worker tick then heartbeat write (the api/deals.mjs order), API discovery().enabled===true, API request() returns state queued, worker tick+heartbeat again.

Expected: request rejected with deal_worker_unavailable, or the case left queued until a configured worker exists.

Actual: case state blocked, error authority_closed, advance count 0, deal-case-capacity.total===1, deal-case-daily principal::total===1, a repeat request returns the dead blocked case, and discovery().enabled is still true.
mediumreleaseUnsent cancels prepared payments that are still submittable or merely paused, and advance() then mislabels the case authority_closedruntime/arbitration-ports.mjs:18
reconcile() runs releaseUnsent for every reserved allocation, before tick() and without taking the case lease.

It cancels any payment in signing/signing_unknown/prepared state as soon as (a) offer.expiresAt<=now()+60000, although submit() still accepts until deadline>now+15 and a concurrent invocation (minute cron, 300 s maxDuration) may already have passed the line-29 check and be between prepare and submit; or (b) allowed(caseId) is false, which includes a temporary operator enabled:false with the same generation.

When advance() later reads payment.status() it finds cancelled and throws authority_closed (line 29), which this commit made permanent.

Three consequences: a payment that was about to be submitted is killed and the deal's single case is lost; an expired never-submitted quote is recorded on the public case as authority_closed instead of oracle_quote_expired, because reconcile runs before tick (the oracle_quote_expired branch is unreachable in the api/deals.mjs order); and a brief operator pause that does not bump the generation permanently kills every in-flight prepared case on re-enable, which docs/paid-deals.md does not state.

Money is not lost (the submit fence holds), but the label is wrong and the case outcome is wrong.

Fix: release on expiry only once nothing can be submitted any more (expiresAt<=now(), i.e. after the submit deadline) and skip allocations whose case holds an unexpired lease; check offer expiry before the cancelled check so the public error is oracle_quote_expired; and either document that an operator pause is terminal for admitted cases or release only when the case is terminal or the offer has really expired.

Test R4: admitted case oracle-pending, allocation q1 reserved, offer.expiresAt=now+50000, imd-payments q1 state prepared with deadline now+40s (submit would accept). ports.reconcile() -> imd-payments q1 state cancelled, allocation released-unsent while deal-cases state is still oracle-pending; ports.advance(v) then rejects with authority_closed although the capability record is still enabled.

Test R5: same with offer.expiresAt=now-1; reconcile then tick (api/deals.mjs order) leaves the case blocked with error authority_closed, not oracle_quote_expired.

Test R6: offer expiring in 500 s, operator sets enabled:false with the same generation, reconcile cancels q3; operator sets enabled:true; advance rejects with authority_closed and the case is permanently blocked.
lowNetwork-wide access-policy pause and admin project suspension do not stop an admitted case although the published description says operator suspension doessrc/deals/arbitration.mjs:21
At 935c323 permitted() also called identity.allowed(v.actor,"deal.review",...), which returns false when the active access policy has paused:true (writesEnabled in api/deals.mjs) or project-access is suspended.

The correction removed that call to make admission durable against requester-session revocation, but with it removed the only link between the operator's global pause and the financial worker. tick() now keeps quoting, signing, paying, posting to the native host and signing resolutions while the whole network is paused, and project_access_set {suspended:true} by the operator has no effect either (test/deal-arbitration.test.mjs:15 asserts the continuation).

The only operator action that stops a case is editing network-capabilities/deal-arbitration. docs/openapi.json:727, interfaces/contract.mjs:22 and docs/paid-deals.md say "network operator suspension still stops it" without saying that neither the global pause nor project suspension counts.

Either consult the access policy paused flag in permitted() (it is operator-controlled, not requester-controlled, so it does not reintroduce the party veto) or document that only the deal-arbitration capability record stops processing.

Test R3: admitted case queued, worker health fresh, capability enabled.

The owner publishes and activates an access policy with paused:true; access_policy_get returns paused===true and identity.allowed(actor,"deal.review",{projectId}) returns false. tick(): expected (behaviour at 935c323 and the documented operator suspension) no advance and authority_closed; actual: advance is called once and the case moves to oracle-pending.
lowreconcile() reads at most eight allocation rows with no cursor, so later reservations are never released or settledruntime/arbitration-ports.mjs:58
store.list returns rows ordered by id with limit 8 and the loop never pages with the after cursor. Rows already settled or released still occupy those eight slots, so any allocation whose id sorts after the first eight is never visited: an expired never-submitted reservation is never released and a submitted payment is never reconciled or cost-settled from this path.

Today the lifetime cap of eight cases keeps the bound latent, but it silently breaks once the cap is raised, a second chain pin shares the store, or a case ever produces a second offer row.

Fix: page with the after cursor until fewer than limit rows return, or iterate only billing=reserved rows.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R7: nine deal-oracle-allocations rows a1..a9, all billing reserved with offer.expiresAt in the past and a caseId that does not exist (so releaseUnsent should release each), 9000 units funded and 9x1000 reserved. ports.reconcile() five times.

Expected: all nine released-unsent, reserved balance 0.

Actual: a1..a8 become released-unsent, a9 stays reserved and the balance stays reserved:"1000" after any number of runs.
lowDeterministic verification failures and provider-format mismatches are retried every minute with provider calls and never reach a terminal statesrc/deals/arbitration.mjs:46
Only six error codes are permanent. Errors that depend solely on already-checkpointed or deterministic state are retried for the life of the dispute window: oracle_prepared_input_mismatch, oracle_question_mismatch, oracle_attestation_mismatch, oracle_signature_invalid, oracle_amount_invalid (all raised by verifyDealOracle on the stored v.oracle), case_binding_mismatch, oracle_admission_mismatch, native_binding_mismatch and a native host 400.

Each retry costs a provider status GET and, for native rejections, a fresh POST of the full input; the case also keeps its active slot and part of the 300 s tick budget until resolutionDue-3600 passes and deal_not_reviewable blocks it.

The same shape exists one step earlier in adapters/imd-oracle.mjs:94: quote() only persists {quote,preparedInput} after the unpaid 402 probe passes validateOraclePrepared, whose shape() requires exactly the keys {pinned,questionHash,request} and {fromBlock,toBlock,toBlockHash}; if the provider wrapper ever carries one extra key the validator throws before the store write, the order row stays at quote:null and every later tick POSTs /requests/quote and the /submit probe again with no terminal outcome.

Rejecting a changed wrapper is correct; the missing piece is a recorded terminal failure (or a bounded attempt count) so the parties can see why the case died and the provider is not polled indefinitely.

Test R12: ports.advance throws oracle_attestation_mismatch; three ticks 130 s apart call advance three times, the case stays queued with no error and remains in deal-case-capacity.active.

Expected: state failed with the code and removal from active.

Test R9: provider /submit 402 returns input.pinned with one extra key fromBlockHash and an otherwise valid quote; provider.quote() called three times rejects with invalid_shape each time, /requests/quote and /submit are each called 3 times, imd-orders[key].quote===null, no imd-offer-index row.
lowvalidateOraclePrepared normalizes a provider-supplied allowAmbiguous:null to false and accepts itsrc/deals/decision.mjs:11
The comment says only the documented false default is normalized, but the nullish-coalescing operator also maps an explicit null to false. The provider inputHash is computed over the wrapper as returned (with null), so quote.inputHash===hash(preparedInput) still passes and the worker proceeds to reserve, sign and pay for a request whose allowAmbiguous holds a value this code never chose and whose provider-side meaning the unpaid probe did not verify.

The stated design is to reject any changed allowAmbiguous.

Fix: const a=value.request?.allowAmbiguous; requireThat(a===undefined||a===false,"oracle_prepared_input_mismatch") before the canonical comparison.

Test R8: expected=oracleInput(case); value={request:{...expected,allowAmbiguous:null},pinned:{fromBlock,toBlock,toBlockHash:<32-byte hex>},questionHash:<32-byte hex>}. validateOraclePrepared(value,expected) returns value with request.allowAmbiguous===null.

Expected: throws oracle_prepared_input_mismatch, as it does for true and for the string "false".
lowSeparate-worker deployment config does not exclude the public API functions, so gateway/compile/workflows handlers are deployed into the process that holds the payment and arbiter keysdeploy/deals.vercel.json:2
docs/paid-deals.md says the private host receives the funded IMD payer key, the unfunded resolution signer and the sealing key, and that the public API never receives either signing key. Vercel deploys every file under api/ as a serverless function regardless of the functions map, and .vercelignore excludes only node_modules, .git, test, contracts, public, sqlite and env files.

A deployment of this repository with deploy/deals.vercel.json as its vercel.json therefore also serves /api/gateway, /api/compile, /api/workflows, /api/domains and /api/workers from the same project whose environment contains CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY, and /api/compile and /api/workflows run there against the shared database when the second project also sets CRON_SECRET.

Those handlers do not read the keys today, so there is no direct leak, but the stated isolation boundary (keys only in a process that runs the worker) is not what the configuration produces. Nothing in the repository selects the deploy file either: the root vercel.json schedules /api/compile and /api/workflows only, so a worker project created without a --local-config step never ticks arbitration (safe but silent: deal_worker_unavailable forever).

This could not be executed here; it follows from Vercel api/ auto-detection and the absence of any exclusion.

Fix: add a worker-specific ignore or move api/deals.mjs into its own minimal project root so only the deals function is built in the key-holding deployment, and record in the operator docs how the deals config is selected.
Configuration inspection, not executed (no deployment).

State: a Vercel project created from this repository with deploy/deals.vercel.json copied to vercel.json and the deal keys in env.

Input: GET https:///api/gateway?__claus_route=/v1/health.

Expected: 404, only /api/deals exists in the key-holding deployment.

Actual per Vercel function detection: the public gateway handler is built and executes inside the deployment whose environment contains CLAUS_DEAL_PAYMENT_KEY and CLAUS_DEAL_ARBITER_KEY; ls api shows six handlers and .vercelignore excludes none of them.
infoAttested request window is bound by whole-object canonical equality, an assumption about an unprobed provider response that fails only after paymentadapters/deal-oracle-proof.mjs:12
The new binding compares canonical(q.window) with canonical(preparedInput.pinned), i.e. exactly {fromBlock,toBlock,toBlockHash}. The 402 challenge input format was confirmed by the unpaid probe, but the attested request object returned by GET /oracle/requests/{id} was not (no panel was opened), and the previous code only read the three fields from it.

If the attested window carries one more key (fromBlockHash, pinnedAt, chainId), verifyDealOracle throws oracle_prepared_input_mismatch after the IMD payment has been made and settled, which the finding at src/deals/arbitration.mjs:46 shows is then retried every minute until the dispute window closes: panel fee spent, no decision. Retained assumption rather than a demonstrated mismatch.

Fix: bind the three pinned fields individually (q.window.fromBlock, toBlock, toBlockHash each === preparedInput.pinned.*), which is what the attestation message already pins.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R10: a valid attested request/attestation pair (passes verifyDealOracle with workerAmount "600") with request.window changed to {fromBlock:96,toBlock:97,toBlockHash:,fromBlockHash:<32-byte hex>}; attestation unchanged and still matching all pinned fields and preparedInput.

Expected: accepted, since the three pinned fields equal the stored prepared input and the attestation blockHash.

Actual: rejects with oracle_prepared_input_mismatch.
infoSigner re-validates with the 3600 s admission margin, so the 60 s resolution_expired check is unreachable and the effective processing window ends an hour before expirysrc/deals/decision.mjs:33
validateDealDecisionShape requires proposal.expiresAt > now+3600 and runtime/arbitration-ports.mjs:38 re-runs it on every tick, including the tick whose only remaining work is to read an already completed native approval and sign. The native host itself only requires authorizationActive (expiresAt > now) and the escrow accepts resolve until expiresAt.

So for any case whose approval lands in the window (expiresAt-3600, expiresAt-60] the worker throws network_review_invalid_input, retries each minute and is finally blocked as deal_not_reviewable; the paid panel result and the Claus approval are discarded. The dedicated signing-time check resolution_expired at arbitration-ports.mjs:51 can never fire.

This is consistent with docs/deal-audit-response.md ("existing processing retains its one-hour margin") and with observed() using processingRemainingSeconds=3600 in tick, so it is recorded as a documented limit with dead code rather than a defect; note that proposal.expiresAt=min(resolutionDue,attestation.expiresAt), so the window can also close an hour before the attestation expiry.

If signing with less than an hour left is intended, separate the admission margin from the signing margin.

Every test there passes on the current tree, which demonstrates the defect it names.

Test R11: native input built exactly as test/deal-arbitration.test.mjs does (valid attestation, pins, proposal.expiresAt=min(resolutionDue,attestation.expiresAt)); validateDealDecisionShape(native,pins,now) passes; the same call with now=(proposal.expiresAt-3540)*1000 (59 minutes before expiry, when the contract would still accept the resolution) throws network_review_invalid_input.
infoPer-owner subsidy limits are keyed by requesting principal, not by onchain party address, so one provider address can occupy every subsidized casesrc/deals/arbitration.mjs:31
Retained assumption acknowledged in docs/deal-audit-response.md, recorded with the concrete bound. Limits are keyed on projectId and project.ownerId (the principal of the signing address); the party check only requires the owner address to be buyer or worker.

A single provider address W can be the worker in deals with buyers B1..B4 (four sign-ins, four principals, four projects); each buyer requests one case per UTC day, so four cases on day 1 and four on day 2 exhaust cases:8 with W in every case, at a cost of four escrows of 0.0001 ETH plus gas, while the network pays up to 0.5 IMD plus inference per case.

An additional counter keyed on each onchain party address (e.g. two lifetime cases per address) would raise the attacker cost to eight distinct addresses without changing the economic rules.
Reproduction file: test/scratch/judge-repro.test.mjs (node --test).

Every test there passes on the current tree, which demonstrates the defect it names.

Test R13: two principals (owner and bob) each owning a project, each the buyer of a distinct deal that shares worker address W.

Both request() calls return queued and deal-case-capacity.total===2; no per-address counter rejects the second.

Extending to four principals per day over two days reaches total 8 with W in every case.
