• 1.lowIntroduced: agent hard-codes a 16384 output cap that an unpatched payer refuses; the ordering dependency is undocumented and each mis-ordered review fails terminally for its input hashintegration/agent-review/network-review-schema.ts:148

    max_output_tokens:16384,stream:false,store:false,

  INTRODUCED DEFECT (merged from audit_flow and audit_economics; both reproduced). Before this patch every review body carried max_output_tokens <= 4096, which every payer build accepts.

  The patch makes the agent emit a constant 16384 for every new review while only the patched payer's review lane (createCreditCompletion with maximumOutputTokens:16384, credit-provider.js:39-45) accepts it; the parent-commit handler and the patched default lane both refuse it through validateRequest's output>8192 check (vendor/src/policy.js:17).

  The two mirrors run in separate deployments (integration/agent-review/README.md) and docs/review-output-budget.json records publicationIsActivation:false with no deployment order. If the agent change is live while the payer is at ea60511 (or the payer is later rolled back), the relay answers HTTP 400 {error:'request_refused',payment:'not_signed'} before any reservation.

  In runNetworkReview that body is not in the deferral allowlist (network-review.ts:120-122), so if(!response.ok)throw marks the row 'uncertain'. The uncertain row holds the single-active unique index claus_network_review_active for the 800 s delivery window, so every other submitNetworkReview raises network_review_capacity meanwhile.

  After 800 s networkReviewStatus asks GET /api/requests/:id, receives 404 not_found (no credit, work or x402 row exists) and terminally sets state 'failed', result {error:'inference_not_reserved'} (network-review.ts:160-162).

  Because the review id is nr_ and submitNetworkReview returns the existing row for the same id, that proposal can never be reviewed again without changing its input; the failed row also still counts toward the 8-per-day limit (network-review.ts:66). No money is spent. The reverse order (payer first) is safe: the widened lane still accepts 1..16384, verified with a 4096 body on both handlers.

  Note: the claim that the payer additionally fences the id in claus_payment_ids via confirmAbsent could not be checked because src/budget.js is not mirrored.

  Fix that preserves the intent: make the payer widening a stated precondition of the agent release (deploy and verify the payer lane first and record that order in docs/review-output-budget.json), or have the agent read the lane's maximum from a relay-advertised value (for example in the /api/admission response) and fall back to <= 8192 when it is absent or lower.

  whole finding

  Payer side, scratch harness around the real handlers (test/scratch/harness.mjs, stubs for the non-mirrored request-budget/transport modules, in-memory store): the parent-commit createCreditCompletion (git show ea60511:integration/payment-review/src/credit-provider.js) built as the review lane (forceStream:false, allowSmallerOutput:false, allowCapacityDeferral:true) given the post-patch review body {model:'gpt-6-astra',provider:'openai',reasoning:{effort:'xhigh',context:'all_turns'},max_output_tokens:16384,stream:false,store:false,instructions,input:[...]} with Idempotency-Key network-review:nr_<64 hex> returns status 400 {error:'request_refused',payment:'not_signed'}; the patched handler with maximumOutputTokens:16384 returns 200, quotes max_output_tokens 16384 once, forwards the paid body byte-identical to the original (JSON.stringify equality true) and stores request_hash = sha256(original body).

  The same 4096 body is accepted (200) by both handlers.

  Agent side, the real network-review.ts run via esbuild with a scripted database and relay (test/scratch/agent-harness.mjs): queued row with request.max_output_tokens 16384, admission GET answers ready/surplus_credit, POST /api/completion answers 400 {error:'request_refused',payment:'not_signed'}.

  Expected: review dispatched, or deferred under the same id.

  Actual: runNetworkReview issues UPDATE ...

  SET state='uncertain' and returns state 'uncertain'; networkReviewStatus inside the 800 s window makes no relay call and returns 'uncertain'; with started_at 900 s in the past and GET /api/requests/:id answering 404 {error:'not_found'} it issues UPDATE ...

  SET state='failed',result='{"error":"inference_not_reserved"}' and returns state 'failed'.

• 2.infoUnchanged mechanism, exposure widened: credit-lane telemetry reports effectiveMaxOutputTokens from the sent request and ignores the provider's x-si-adapted-params headerintegration/payment-review/src/credit-provider.js:172

  effectiveMaxOutputTokens:transport?(normalized.tokenLimitAdapted?null:quoted.request.max_completion_tokens):quoted.request.max_output_tokens

  EVIDENCE-INTEGRITY LIMITATION, not a new bypass (from audit_permissions; the code behaviour is reproduced, the provider behaviour is not). The native credit lane sets telemetry.effectiveMaxOutputTokens to quoted.request.max_output_tokens, i.e. what was sent, and never reads the provider's x-si-adapted-params header, whereas the x402 lane's responseMetadata (vendor/src/response.js:5) does capture that header.

  Until this patch every credit request was at or below the 8192 bound that the vendored validateRequest mirrors; the review lane now sends 16384, above that mirrored bound, and docs/review-output-budget.json records paidModelCalls 0, so no paid call has shown that the provider executes 16384 rather than adapting it.

  If the provider did adapt, the stored result and the agent's failed-review evidence (finish() stores the whole inference result on incomplete_or_invalid_model_result) would state that a 16384 budget was in effect when it was not, misleading the next correction. No spending or verdict integrity is affected: cost comes from x-si-buyer-cost-micro and an incomplete result is still rejected.

  If this matters, read x-si-adapted-params on the credit lane as the x402 lane does, store it in telemetry and derive effectiveMaxOutputTokens from it when present, and confirm one paid call at 16384 before relying on the budget.

  whole finding

  Scratch harness (test/scratch/harness.mjs): patched review lane, 16384 body, stub provider answering HTTP 200 with headers x-request-id, x-si-buyer-cost-micro: 468507 and x-si-adapted-params: max_output_tokens=8192, body {status:'incomplete',usage:{output_tokens:8192,buyer_cost_micro:'468507'},...}.

  Expected: the saved telemetry shows the adapted parameter.

  Actual: the returned/stored telemetry keys are paymentScheme,actualMicroUsdc,latencyMs,requestedMaxOutputTokens,effectiveMaxOutputTokens,requestedInputItems,effectiveInputItems with requestedMaxOutputTokens 16384 and effectiveMaxOutputTokens 16384 and no adapted-params field.

  Whether the live provider adapts above 8192 is unverified; no paid call was made.

• 3.infoUnchanged limitation: the 600 s provider deadline is not widened with the 4x larger reasoning budget; a time-cut review still ends failed with its 2 USDC hold retainedintegration/payment-review/vendor/src/response.js:12

      ? {providerMs:600000,activeMs:760000}

  UNCHANGED LIMITATION, listed by declared scope ('deadline' unchanged); merged from four specialists (audit_flow, audit_permissions, audit_economics, audit_math). completionTiming(false,'research') still yields providerMs 600000 / activeMs 760000, signal() subtracts a further 30 s (credit-provider.js:89-93), and the agent keeps its 650 s POST timeout and 800 s status window.

  The patch raises the longest legitimate generation from 4096 to 16384 reasoning+output tokens at effort xhigh on inputs of up to ~900 kB canonical evidence without measuring the elapsed time of the failed 4096 call, so the binding limit on a slow review can move from the token cap to the time cap.

  When the local abort fires after startCredit, submitting is true, so finishCredit stores status 'uncertain' with amount null: released = reserved_max - COALESCE(accounted_cost, reserved_max) = 0, and expireCredit later releases nothing for a non-reserved row (credit-work-store.js:39-47, 87-101), so the 2,000,000 microUSDC committed against the lifetime ceiling stays committed until separate reconciliation.

  The agent then records failed/inference_delivery_unknown with paymentHoldRetained:true and never retries, the same outcome as the incident this patch addresses, reached by a different limit. If the provider instead returns x-si-truncated: 1, the cost is kept and the result is marked incomplete (credit-provider.js:171) and parseNetworkDecision rejects it.

  This is the documented behaviour for any timeout; it is reported so the next correction measures the first paid 16384 call's latency instead of treating a timeout as a new bug. If it matters, raise providerMs for the review lane in step with the output budget, keeping activeMs, the relay's 750 s stream maximum and the agent's 650 s fetch timeout consistent.

  whole finding

  Code trace only; not reproduced against the live provider because no paid calls were made.

  State: review lane admitted, reservation and startCredit succeeded.

  Input: a provider generation still running at started + min(600000, activeMs-elapsed-30000) ms (for example 16384 tokens generated at under ~29 tokens/s after the 135k-token prefill of the cause).

  Expected per the patch's goal: a complete JSON verdict.

  Actual: AbortSignal.timeout fires, the catch at credit-provider.js:176-185 saves status 'uncertain', payment 'unknown', amount null; claus_payment_budget.committed stays increased by 2,000,000; after the 800 s window networkReviewStatus (network-review.ts:154-158) sets the review failed with inference_delivery_unknown and paymentHoldRetained true.

• 4.infoUnchanged limitation: the 2 USDC ceiling with no quote shrinking now applies to a 16384-token quote, narrowing the affordable input range by roughly 58261 microUSDCintegration/payment-review/src/index.js:67

    const reviewCredit=createCreditCompletion({env,sql,fetcher,paidFetch,store:creditWork,forceStream:false,allowSmallerOutput:false,allowCapacityDeferral:true,maximumOutputTokens:16384});

  UNCHANGED LIMITATION, by declared scope ('2-USDC per-call ceiling' and 'no quote shrinking' unchanged); merged from audit_economics and audit_math. The review lane keeps allowSmallerOutput:false, so quoteWithinBudget (vendor/src/quote.js:35) never steps 16384 down to 4096/2048 and validateChallenge throws quote_refused when the unsigned quote exceeds min(pool remaining, caller 2000000).

  From docs/review-output-budget.json (accounted 468507 micro at 4096 output tokens, unsigned quote 526768 at 16384 for the same ~135689-token input) the extra reservation adds about 58261 micro per request, so a review whose 4096-token quote already sat between roughly 1941739 and 2000000 micro would now be refused instead of dispatched.

  The failure is clean and unpaid: outcome credit_quote_rejected, status failed, payment not_signed, accounted_cost 0, no provider call, 502 to the agent; the agent marks the row uncertain and later fails it via /api/requests with verified_nonpayment accounting. Extrapolating the cause's prices to the 900000-byte canonical input cap gives a quote well under 2000000, so the band is probably unreachable with current pricing.

  No change is required; whether review quotes may shrink or the ceiling should scale is a design decision outside this patch.

  whole finding

  Scratch harness (test/scratch/harness.mjs): patched review lane, 16384 body, stub quote endpoint answering 402 with accepts[0].amount '2000001' and caller/pool maximum 2000000.

  Expected per the declared design: refusal without payment.

  Actual: exactly one quote candidate (max_output_tokens 16384) is tried, the handler returns 502 {error:'payment_requires_reconciliation',id} and the stored work row is status 'failed', accounted_cost '0', outcome {rail:'surplus_credit',failure:'credit_quote_rejected',payment:'not_signed'}.

  The real price table is not mirrored, so the exact input size at which this triggers cannot be computed from this tree.

• 5.infoUnchanged trust assumption, widened: the 16384 lane is selected by the caller-chosen Idempotency-Key pattern alone, so any INFERENCE_SECRET holder can obtain the widened budgetintegration/payment-review/src/index.js:68

    const workHandler=id=>/^network-review:nr_[a-f0-9]{64}$/.test(id)?reviewCredit:independentCredit;

  TRUST ASSUMPTION, not a monetary bypass (from audit_permissions; reproduced on the handler). workHandler picks reviewCredit purely from the idempotency key matching network-review:nr_<64 hex>; createCreditCompletion never inspects the id and nothing on the relay checks that such an id corresponds to a persisted claus_network_reviews row or that the body is a review request.

  This routing predates the patch; what the patch adds is that the pattern now also grants a 16384 output budget that no other caller of the same INFERENCE_SECRET can obtain (the default lanes refuse 8193+). The agent's Builder flows and the review flow share INFERENCE_SECRET (relay() in network-review.ts), so any process holding it can mint a review-shaped id.

  Exposure stays bounded by the unchanged 2 USDC quote ceiling, the single active work slot and the lifetime ceiling, so this is a boundary to document rather than a defect to fix in this patch. If a tighter boundary is wanted, bind the widened cap to evidence only the agent produces (for example require the review body's instructions to carry the fixed review preamble, or have the agent sign the id), which is a design decision outside this patch's scope.

  whole finding

  Scratch harness (test/scratch/harness.mjs): the patched handler built as index.js builds reviewCredit (maximumOutputTokens:16384) accepts a 16384 body under Idempotency-Key network-review:nr_aaaa...(64 hex) with instructions 'review' and a one-item input, reserves, quotes and dispatches it (200); the same body under a build_<24 hex>:model:1 id on the default handler is refused with 400 request_refused.

  In index.js:141 and :158 the only selector between the two handlers is the regex at line 68; no persisted review or body shape is consulted.

  Reproduced in the handler harness, not against a running relay.

1. Posted6 minto the first attempt
2. Audit flowAgent #956found 1 low, 1 info

   Review complete. The findings file is written at the repository root and validated against the tree.

   Outcome. The patch introduces no boundary bypass, mutation or replay path, route leak, or evidence-integrity defect that I could substantiate. I found one low-severity rollout coupling and recorded one unchanged limitation, as the task asked for them to be reported separately.

   What I verified

   • The committed tree matches docs/review-output-budget.patch exactly.
   • With a scratch harness loading the real credit provider, the review lane accepts 1 to 16384 tokens, refuses 0 and 16385, and still refuses an extra field, 161 inputs, an invalid effort, and non-object bodies on the cloned validation view.
   • The quoted body and the paid dispatch both carry the original 16384 value. The default lane used by the pilot and Builder handlers still refuses 16384, and the constructor rejects any other cap.
   • The widened handler is reachable only for ids matching the strict network-review pattern, both for fresh admission and for saved rows.
   • Old queued or failed review rows keep their saved 4096 request and identity. The failed request is not repaid, and the input-hash id prevents replay under the new budget.

   Findings recorded

   • Low, introduced. The agent builder hard-codes 16384 with no coupling to what the relay accepts. If the agent mirror ships before the payment mirror, every new review gets a 400 refusal, sits in the uncertain state for 800 seconds while blocking all other submissions, then fails permanently with inference_not_reserved and burns a daily slot. Fix by deploying the payment side first and recording that order, or by deriving the cap from an advertised relay capability.
   • Info, unchanged limitation. The 600 second provider deadline was not raised with the four times larger generation budget. A timeout after dispatch leaves the 2 USDC commitment permanently held, which is existing behaviour but becomes more likely per review.

   Not verified. No paid provider call was made, so acceptance of 16384 by the live model was not tested beyond the unsigned quote recorded in the change note. The agent's own inference transport and configuration module are not in the mirror and were not inspected.

   • lowAgent now emits a fixed 16384 output cap that the unpatched payment relay refuses; shipping the agent mirror before the payment mirror permanently fails every new reviewintegration/agent-review/network-review-schema.ts:148

     INTRODUCED. The agent-side request builder no longer derives the cap from configuration or from anything the relay advertises; it hard-codes 16384. The two mirrors run in separate deployments (integration/agent-review/README.md) and docs/review-output-budget.json records no ordering requirement (publicationIsActivation:false).

     The relay only accepts 16384 for the review lane after integration/payment-review/src/credit-provider.js:39-44 is live; the previous validateRequest (vendor/src/policy.js:17, output>8192) refuses it with 400 request_refused / payment not_signed.

     In runNetworkReview (integration/agent-review/network-review.ts:115-133) that reply is not in the deferral allowlist, so the review is marked uncertain, holds the single-active unique index claus_network_review_active for at least 800 s (every further submitNetworkReview raises network_review_capacity), then networkReviewStatus reads the payer 404 not_found and terminally sets failed/inference_not_reserved.

     Each such row still counts toward the 8-per-day limit, and because the id is nr_, the same proposal can never be reviewed again without changing its input. No money is spent.

     Fix: deploy the payment mirror first and record that order in the change note, or derive the review cap from a relay-advertised capability (for example the /api/admission response) and fall back to 8192 when absent.

     whole finding

     State: agent deployment at this commit; payment relay at the parent commit (ea60511), or any relay whose review lane is built without maximumOutputTokens:16384.

     Input: submitNetworkReview(validInput) then runNetworkReview(id) with admission ready.

     Expected: the saved request is quoted and dispatched, or deferred with admission:deferred.

     Actual: POST /api/completion returns 400 {"error":"request_refused","payment":"not_signed"}; the review row becomes state uncertain, then failed {"error":"inference_not_reserved"} after 800 s; concurrent submissions throw network_review_capacity meanwhile.

     Verified with test/scratch/drive.mjs, which loads the real credit-provider.js: a handler built with the default maximumOutputTokens (identical to the pre-patch validation path) answers a 16384-token body with 400 request_refused, while the 16384 lane accepts it and forwards max_output_tokens 16384 unchanged in both the quote and the paid dispatch.

   • infoUnchanged limitation: the fixed 600 s provider deadline is not widened with the 4x larger reasoning budget; an over-long generation strands a permanent 2 USDC holdintegration/payment-review/src/credit-provider.js:123

     UNCHANGED LIMITATION, not an introduced defect; reported separately as the task asks. completionTiming(false,'research') (vendor/src/response.js:13) still gives providerMs 600000 / activeMs 760000, and signal() subtracts a further 30 s, so the paid dispatch is aborted after roughly 570 s.

     The patch raises the maximum generation from 4096 to 16384 reasoning+output tokens at effort xhigh on inputs of up to ~900 kB canonical evidence, which lengthens the longest legitimate response without touching the deadline.

     When the abort fires after startCredit, submitting is true, so finishCredit stores status uncertain with amount null: accounted_cost stays NULL, released is 0, and expireCredit later releases nothing, so the 2,000,000 microUSDC committed against the lifetime ceiling is never returned (credit-work-store.js:87-101, 39-47). The agent then records failed/inference_delivery_unknown with paymentHoldRetained:true and never retries.

     This is the documented behaviour for any timeout, but the probability per review rises with this patch; the change note lists the deadline as intentionally unchanged. If it matters, raise providerMs for the review lane in step with the output budget, keeping activeMs and the agent 650 s fetch timeout consistent.

     whole finding

     State: review lane admitted, reservation and startCredit succeeded.

     Input: a provider response that has not completed 570 s after dispatch (for example 16384 tokens generated at under 29 tokens per second after a 135k-token prefill).

     Expected per the change note: unchanged; the request is aborted.

     Actual: AbortSignal.timeout fires, the catch at credit-provider.js:176-185 saves status uncertain / payment unknown with no cost, claus_payment_budget.committed remains increased by 2,000,000 permanently, and the agent review ends failed with inference_delivery_unknown.

3. Audit mathAgent #912found 2 info

   The review is complete. The findings file is written and validated, and the repository tree is untouched apart from .imd-findings.json.

   Result: no introduced defect found in the patch. The two entries in the findings file are info-level notes on unchanged limitations, labeled as such, so the requester can tell them apart from actionable defects.

   What I checked, in the order the scope asks for:

   • Boundary bypass. The review lane accepts max_output_tokens 1 to 16384 and runs every other original check on a clone capped at 8192. I drove the handler with stubbed dependencies: 16385, 0, 1.5, a string, a missing field, negative zero, non-object bodies and a body carrying an own __proto__ key are all refused on both lanes. 8193 passes only on the review lane, and the constructor rejects any limit other than 8192 or 16384.
   • Mutation and replay. The request hash, quote, payload hash and dispatched body all use the original parsed request, not the clone. A resend of an existing ID with a different output cap hits the hash mismatch and returns a conflict. The failed review keeps its 4096 body because the agent sends only the saved request, and resubmitting the same input returns the existing failed row.
   • Route isolation. Only IDs matching the review pattern reach the 16384 handler. The pilot and Builder lanes keep the 8192 default, and the Builder transport adapter is never constructed on the review lane.
   • Evidence and result integrity. The strict complete-JSON verdict parser is unchanged. The maximum valid verdict is about 7,900 characters, so it still fits the 8,000-character content cap. The mirror file hashes match the three hashes in the scope document. The older agent source binding pins a pre-patch hash, but that document explicitly describes itself as historical, so it is not a defect.

   The two unchanged limitations recorded as info:

   1. The provider deadline stays at 600 seconds while the token budget quadruples. A review still generating at about 570 seconds now fails by time rather than tokens, is still charged, and ends failed with its hold retained.
   2. The 2 USDC quote ceiling with no shrinking now applies to the 16384-token quote. From the figures in the scope document, the wider allowance adds about 58,000 micro USDC per request, so a request already near the ceiling would be refused cleanly without payment. This band is probably unreachable under the 900 KB input cap.

   Tools run: a Node harness in /tmp against copies of the patched validator, since the mirror omits several modules the handler imports and no Foundry contract is involved. No Solidity changed, so no proof tests apply. The temporary directory was removed.

   • infoUnchanged limitation: provider deadline stays 600s while the review token budget quadruples, so a slow generation now fails by time instead of by tokens and is still chargedintegration/payment-review/vendor/src/response.js:12

     NOT an introduced defect; reported separately as an unchanged limitation the patch interacts with. The patch raises max_output_tokens for the trusted review lane from 4096 to 16384 (integration/agent-review/network-review-schema.ts:148, credit-provider.js:39-44) but leaves completionTiming(false,'research') at providerMs 600000 / activeMs 760000, and the provider abort at credit-provider.js:89-93 at min(600000, deadline-now-30000).

     With four times the reasoning budget at effort xhigh and ~135k input tokens, the binding limit on a long review can move from the token cap to the time cap. Either the provider cuts the response and sets x-si-truncated=1 (credit-provider.js:171 marks it incomplete, cost retained) or the local AbortSignal fires (catch at line 176 saves status uncertain with payment unknown because submitting=true).

     In both cases parseNetworkDecision (network-review-schema.ts:154) throws network_review_incomplete and the review row ends failed with its hold retained, the same outcome as the incident this patch addresses, just by a different limit. This is consistent with the declared scope (timeout unchanged) and no retry is implied; it is listed so the requester can decide whether 600s is still the right ceiling for a 16384-token xhigh review.

     whole finding

     State: a review request on the network-review lane (id network-review:nr_<64 hex>) whose provider generation is still running at started+570000 ms.

     Expected per patch intent: a complete JSON verdict within the 16384-token budget.

     Actual: credit-provider.js signal() aborts (TimeoutError) or the provider returns x-si-truncated: 1; the saved result has responseStatus incomplete or status uncertain, parseNetworkDecision rejects it, claus_network_reviews.state becomes failed (incomplete_or_invalid_model_result or inference_delivery_unknown) while the 2 USDC hold stays reserved.

   • infoUnchanged limitation: the 2 USDC quote ceiling with no shrinking now applies to a 16384-token quote, so a request that fit at 4096 can be refused at quoteintegration/payment-review/src/credit-provider.js:99

     NOT an introduced boundary bypass; a safe consequence of the widened output allowance under the explicitly unchanged 2 USDC per-call ceiling and no-quote-shrinking rule. The review lane is created with allowSmallerOutput:false (index.js:67), so quoteWithinBudget never steps 16384 down to 4096/2048; validateChallenge (vendor/src/policy.js:30) throws quote_refused when the unsigned quote exceeds maximum (min(pool remaining 2000000, caller 2000000)).

     From the figures in docs/review-output-budget.json (accounted 468507 micro at 4096 output, unsigned quote 526768 at 16384 for the same ~135689-token input) the extra output allowance adds about 58261 micro per request. A review whose 4096-token quote already sat between roughly 1941739 and 2000000 micro would therefore now be refused instead of dispatched.

     Failure is clean: outcome credit_quote_rejected, status failed, payment not_signed, accounted_cost 0, no provider call; the agent marks the row uncertain on the 502 and later fails it via /api/requests with verified_nonpayment accounting. Given the 900000-byte canonical input cap this band is probably unreachable with current pricing, so this is informational only.

     whole finding

     State: a network-review request whose unsigned 'upto' quote for the saved 16384-token body exceeds 2000000 micro-USDC.

     Expected per the declared design: refusal without payment (this is the intended behaviour).

     Actual: identical, refusal without payment; listed only so the requester knows the affordable input range narrowed by ~58261 micro compared with the 4096 body.

     Not reproducible from this tree because the provider price table is not mirrored.

4. Audit permissionsAgent #646found 2 low, 2 info

   Review complete. The findings file holds four entries, none above low severity, and no file in the tree was modified.

   What I verified

   • The patch in docs/review-output-budget.patch is exactly the HEAD commit's diff to the three integration files, and the three mirror hashes in docs/review-output-budget.json match the tree.
   • I ran the patched credit provider in a stubbed harness outside the repository. The review lane accepts max_output_tokens 1 through 16384 and refuses 0 and 16385. The default lane still refuses 16384. Unsupported fields and oversize input arrays are still refused on the review lane. The quote and reservation hash use the raw body with 16384, so the saved, quoted and sent request is unchanged.
   • Route isolation holds as described: the widened handler is reached only through the review ID pattern, and the 2-USDC quote ceiling, no-shrink quote, deadlines, accounting and strict complete-JSON verdict are untouched.
   • Replay is safe: the agent never regenerates a persisted request, and the relay's hash check rejects a body that differs from the saved one.

   Findings written to .imd-findings.json

   • Low, introduced. The agent now hard-codes 16384, so the configuration cap that was previously honoured and whose hash is bound to every review row no longer limits the review request. Concrete state: settings.maxOutputTokens 2048 still yields a 16384 request.
   • Low, introduced exposure. The credit lane reports effectiveMaxOutputTokens as whatever was sent and never reads the provider's adapted-params header, which the x402 lane does read. No paid call at 16384 was made, so a provider clamp to 8192 would be invisible in the saved evidence.
   • Info, unchanged limitation now widened. The review lane is chosen purely from a caller-selected Idempotency-Key pattern. Any holder of the inference secret can mint a review-shaped ID and obtain the 16384 budget, bounded by the unchanged 2-USDC ceiling and single active slot.
   • Info, unchanged limitation. The 600-second provider window is unchanged while the output budget quadruples, and the scope file records no latency for the prior failure. A slow 16384-token response ends on the existing uncertain path with the hold retained.

   Limits of this review

   The mirror omits several imports (request-budget, response-stream, builder-transport, credit-admission and the Hono app dependencies), so the scope file's two targeted tests and typecheck could not be rerun here. I exercised the patched validation branch directly with stubs instead. No Solidity was in scope, so no Foundry proof was needed.

   • low[introduced] Review output budget is hard-coded; the bound agent configuration no longer limits itintegration/agent-review/network-review-schema.ts:148

     Before this patch networkReviewRequest bounded the review request by the operator configuration (Math.min(4096,config.settings.maxOutputTokens)). The patch replaces that with the literal 16384, so the configuration revision/hash that submitNetworkReview binds into every claus_network_reviews row no longer governs the only request parameter that drives reasoning spend and provider latency.

     Decoupling reviews from the conversational reply cap is the stated intent, but the result is that no configuration value can lower the review budget without a code release, while model, provider and reasoning effort stay configuration-controlled. Spend is still capped by the unchanged 2-USDC quote, so impact is bounded.

     Minimal fix that keeps the intent: read a review-specific bound from configuration with 16384 as its default and ceiling, e.g. max_output_tokens: Math.min(16384, config.settings.reviewMaxOutputTokens ?? 16384), so the bound stays visible in the configuration hash recorded with the review.

     whole finding

     State: a configuration whose settings.maxOutputTokens is 2048 (or any value below 16384), settings.enabled true, policy.capabilities.networkReview true.

     Input: networkReviewRequest(validInput, config).

     Expected (pre-patch semantics and the configuration binding recorded on the row): a request bounded by the configuration.

     Actual: the returned request has max_output_tokens === 16384 regardless of any configuration value; the only way to lower it is a new agent release.

   • low[introduced exposure] Saved review telemetry reports effectiveMaxOutputTokens 16384 even if the provider adapts the parameterintegration/payment-review/src/credit-provider.js:172

     The credit lane records telemetry.effectiveMaxOutputTokens from quoted.request.max_output_tokens, i.e. what was sent, and never reads the provider's x-si-adapted-params header; the x402 lane's responseMetadata in vendor/src/response.js does capture that header. Until this patch every credit request was at or below 8192, the value the vendored validateRequest mirrors, so adaptation was not a live case.

     The review lane now sends 16384, above that mirrored bound, and the scope file records paidModelCalls 0: only an unsigned quote (526768 microUSDC) was obtained at 16384, no paid call proved the provider executes 16384 rather than clamping.

     If the provider clamps, the saved result and the agent's failed-review evidence (finish() stores the whole inference result on incomplete_or_invalid_model_result) state that a 16384 budget was in effect when it was not, which misleads the next correction.

     Fix: read x-si-adapted-params on the credit lane as the x402 lane does, store it in telemetry, and derive effectiveMaxOutputTokens from it when present; confirm one paid call at 16384 before relying on the budget.

     whole finding

     State: review lane (maximumOutputTokens 16384), request max_output_tokens 16384.

     Input: provider responds HTTP 200 with headers x-si-buyer-cost-micro: 468507, x-si-adapted-params: max_output_tokens=8192, and a Responses body with status 'incomplete' and usage.output_tokens 8192.

     Expected: the saved response/telemetry shows the adapted parameter so the incomplete verdict is attributed to an 8192 budget.

     Actual: finishCredit stores telemetry.requestedMaxOutputTokens 16384 and telemetry.effectiveMaxOutputTokens 16384 with no adapted-params field; parseNetworkDecision fails the review as before and the stored evidence claims the widened budget was applied.

     Unverified against the live provider: whether it adapts above 8192 is unknown because no paid call at 16384 was made.

   • info[unchanged limitation, widened] The 16384 lane is selected by a caller-chosen Idempotency-Key pattern, not by a registered reviewintegration/payment-review/src/index.js:68

     workHandler picks reviewCredit purely from the idempotency key matching network-review:nr_<64 hex>; createCreditCompletion itself never inspects the id, and nothing on the relay checks that such an id corresponds to a persisted claus_network_reviews row or that the body is a review request. This routing predates the patch; what the patch adds is that this pattern now also grants a 16384 output budget that no other caller of the same INFERENCE_SECRET can obtain.

     The agent's Builder flows and the review flow share the same INFERENCE_SECRET (relay() in network-review.ts reads process.env.INFERENCE_SECRET), so any process holding it can mint a review-shaped id. Exposure stays bounded by the unchanged 2-USDC quote ceiling and the single active work slot, so this is a trust assumption to document, not a monetary bypass.

     If a tighter boundary is wanted, bind the widened cap to evidence only the agent produces (for example require the review body's instructions to carry the fixed review preamble, or have the agent sign the id), which is a design decision outside this patch.

     whole finding

     State: NETWORK_REVIEW_FRESH_RAIL=credit_work, SURPLUS_CREDIT_ENABLED=true, funded pool, no active work.

     Input: any holder of INFERENCE_SECRET POSTs /api/completion with Idempotency-Key network-review:nr_0000000000000000000000000000000000000000000000000000000000000000, X-Inference-Purpose research, X-Max-Quote-Micro-USDC 2000000, and a body {model:'gpt-6-astra',provider:'openai',reasoning:{effort:'xhigh',context:'all_turns'},stream:false,store:false,instructions:'anything',input:[{role:'user',content:'anything'}],max_output_tokens:16384}.

     Expected: only requests generated by networkReviewRequest for a persisted review receive the 16384 budget.

     Actual: the id passes workCandidate and workHandler, reviewCredit accepts max_output_tokens 16384 and quotes it (verified in a stubbed harness of createCreditCompletion: the same body with a build_ id on the default handler is refused with request_refused, the review-shaped id is reserved and quoted at 16384).

     whole reproduction

   • info[unchanged limitation] Provider window stays 600 s while the review output budget quadruplesintegration/payment-review/src/credit-provider.js:123

     The patch raises the review budget from 4096 to 16384 combined reasoning/output tokens but, by declared scope, leaves completionTiming(false,'research') at providerMs 600000 / activeMs 760000, the agent's 650 s POST timeout and the 800 s status window. The scope file records no latency for the failed 4096-token call, so nothing in the submission shows that a response that actually uses 16384 reasoning tokens at xhigh effort returns inside the window.

     The failure mode is the already-corrected uncertain path, not a new defect: the hold is retained and the review ends failed with inference_delivery_unknown. Reported so the next correction measures the elapsed time of the first paid 16384 call instead of treating a timeout as a fresh bug.

     State: review lane dispatch at t0 after quote and balance reads (about 5-30 s).

     Input: provider needs more than min(600 s, 760 s - elapsed - 30 s) to finish a 16384-token response.

     Expected under the patch's stated goal: a complete JSON verdict.

     Actual: providerSignal aborts, the catch path stores status 'uncertain' with payment 'unknown' and no response; after the 800 s window networkReviewStatus marks the review failed with paymentHoldRetained true and the 2-USDC hold stays committed until separately reconciled.

5. Audit economicsAgent #461found 1 medium, 1 info

   The review is complete and the findings file is written at the repository root with two entries, one actionable and one labelled as an unchanged limitation.

   What I checked. The patch in the tree matches docs/review-output-budget.patch exactly, and the three file hashes in the scope file match the mirror files. I ran the real credit handler in a scratch harness, stubbing only the modules the mirror omits, and drove it with the exact request shape the agent now emits. Those runs confirm the patch's own claims: the trusted review lane accepts 16384, forwards it unchanged into both the unsigned quote and the paid body, refuses 16385, still enforces every other request check on the widened clone, keeps the default handler at 8192, and returns a hash conflict when the same id is replayed with a different output budget. Route isolation holds because the widened handler is only reachable through the review id pattern behind the inference secret, and the per-call spend stays inside the unchanged 2 USDC reservation. The older source manifest is explicitly marked historical, so it is not a stale binding.

   Findings written.

   • Medium, introduced. The agent now hard-codes 16384 with no readback of what the payer accepts. If the agent deployment carries this change while the payer is still at the previous commit, the vendor validator refuses the request with an unsigned 400. The agent treats that as uncertain rather than deferred, and after the 800 second window the payer's 404 turns it into a terminal failure. That review id is bound to the input hash, so the proposal can never be re-reviewed, the id is fenced on the payer, one of the eight daily slots is consumed, and the single active slot is held for the whole window. The fix is to make the payer widening a verified precondition of the agent change, ideally with the payer advertising its review-lane ceiling so the agent falls back to 8192 when it is absent.
   • Info, unchanged limitation. The fixed 600 second provider deadline and the no-shrink 2 USDC quote now carry a four times larger output reservation. A generation that needs the full budget can time out with the hold retained, and a near-maximum evidence payload can quote above the ceiling where it previously fit. This cannot be reproduced offline and needs no change within this patch's scope.

   Coverage gaps. The mirror does not include the request-budget module that derives the hash and caller maximum from the 16384 body, so I could not verify it directly. The project's own test suite does not cover the integration mirrors, and the two targeted tests cited in the scope file are not in the tree.

   • mediumIntroduced: agent hard-codes 16384 with no payer readback, so a payer still at the 8192 cap terminally fails and fences every new reviewintegration/agent-review/network-review-schema.ts:148

     The patch couples two separately deployed components through a constant each side hard-codes: the agent mirror now emits max_output_tokens 16384 for every new review, and the payer mirror accepts it only in the reviewCredit handler built with maximumOutputTokens:16384 (integration/payment-review/src/credit-provider.js:39-45).

     Nothing in the patch, the scope file (publicationIsActivation:false, mirrors deployed separately) or the agent's dispatch path checks that the payer it talks to has that widening. Before this patch the agent sent at most 4096, which every payer version accepted, so this ordering dependency is new.

     If the agent deployment carries this change while the payer deployment is still at commit ea60511 (or any build whose /api/completion review lane validates with the vendor validateRequest cap of 8192, integration/payment-review/vendor/src/policy.js:17), the payer answers HTTP 400 {error:'request_refused',payment:'not_signed'} before reserving anything.

     The agent's dispatch loop (integration/agent-review/network-review.ts:120-133) only re-queues on the enumerated admission:'deferred' bodies; a plain 400 falls to if(!response.ok)throw and the row becomes 'uncertain'.

     After the 800 s delivery window networkReviewStatus asks GET /api/requests/:id; the payer finds no credit, work or x402 row, runs confirmAbsent and returns 404 not_found, so the agent marks the review failed with 'inference_not_reserved' (network-review.ts:160-162).

     The consequences are terminal and bounded-resource consuming: (1) the review id is nr_, and submitNetworkReview returns the existing failed row for the same input, so that proposal can never be reviewed again without changing the proposal itself; (2) the id is now in claus_payment_ids as absent, so a later POST with the same id hits a primary-key conflict that reserveCredit rethrows (not the one_active constraint) and surfaces as 503 payment_service_unavailable; (3) the failed row still counts toward the global daily review limit of 8 (network-review.ts:66), and while 'uncertain' it holds the single active slot (claus_network_review_active) for 800 s, blocking every other review.

     The scope file's claim that unchanged 'liveness corrections' cover this lane is not true for this failure: the deferral list was widened only for admission reasons, not for an unsigned request refusal.

     Unchanged by contrast: the reverse order (payer first, agent later) is safe because the widened lane still accepts 1..16384.

     whole finding

     State: payer deployment without this patch (review lane = createCreditCompletion default maximumOutputTokens 8192, i.e. commit ea60511), agent deployment with this patch.

     Input: any newly submitted valid review; networkReviewRequest now returns a body with max_output_tokens:16384.

     Verified against the mirrored code: validateRequest(request with max_output_tokens 16384) from integration/payment-review/vendor/src/policy.js throws 'request_refused' while the same body with 4096 passes; the real createCreditCompletion built with the default cap returns {status:400,body:{error:'request_refused',payment:'not_signed'}} for the 16384 body and the patched handler built with maximumOutputTokens:16384 returns 200 and forwards 16384 unchanged into both the unsigned quote and the paid body (scratch harness around the real handler with the missing transport/request-budget modules stubbed).

     Expected: the review completes or is deferred and retried under the same id.

     Actual: runNetworkReview throws on !response.ok, the row goes 'uncertain', and after 800 s networkReviewStatus receives 404 not_found and sets state 'failed' result {error:'inference_not_reserved'}; the input hash id is permanently failed on the agent and fenced in claus_payment_ids on the payer, and the attempt consumes one of the 8 daily review slots.

     Fix that preserves the intended behaviour: make the payer-side widening a precondition of the agent change (deploy/verify the payer lane first, and record that ordering in docs/review-output-budget.json), and have the agent confirm the ceiling before emitting it, e.g. admission or /health advertising the review lane's maximumOutputTokens (16384) and the agent falling back to min(8192, ...) when the advertised value is absent or lower.

     Alternatively keep the agent at <=8192 until a live payer readback shows the patched handler.

   • infoUnchanged limitation with widened exposure: fixed 600 s provider deadline and unshrinkable 2-USDC quote now carry a 4x larger output reservationintegration/payment-review/src/credit-provider.js:123

     Not an introduced defect; recorded so it is not mistaken for one. The patch leaves completionTiming (providerMs 600000, activeMs 760000), the agent's 650 s client timeout, the relay's 750 s stream maximum and the no-shrink unsigned quote unchanged while raising the reservation from 4096 to 16384 output tokens at reasoning effort xhigh.

     Two existing failure paths therefore gain exposure: (a) a nonstreaming generation that actually uses most of the 16384-token budget on a ~135k-token input must finish inside the 600 s provider signal; if it does not, the handler aborts after dispatch with submitting=true, the work row becomes 'uncertain' with its full 2-USDC hold retained, and the review later terminates as failed with paymentHoldRetained:true while the provider may still bill the completed generation; (b) the unsigned quote scales with the output reservation (526768 micro-USDC for the cause's 135689-token input at 16384), and because allowSmallerOutput is false for this lane an evidence payload large enough to quote above 2000000 fails unsigned with no retry, whereas the same payload quoted at 4096 might have been admitted.

     Neither path can be reproduced offline without provider throughput and pricing, so this is reported as a limitation, not a defect; the economics stay bounded by the 2-USDC per-call reservation and the lifetime ceiling.

     whole finding

     Scenario (a): a review whose xhigh reasoning plus verdict needs more than 600 s wall time at 16384 tokens.

     Expected per design: bounded hold, no approval.

     Actual: same, but the hold is retained for a generation the provider may have completed and billed, with no result captured.

     Scenario (b): an evidence payload near the 900 KB canonical limit whose quote at 16384 exceeds 2000000 micro-USDC.

     Expected: admitted at the lower reservation the old request used.

     Actual: quote_refused, failed not_signed, id terminal.

     No code change is required by this entry; if the operator wants to reduce the exposure, the design decision is whether the review lane's providerMs should scale with the output reservation or the quote may shrink for reviews, both of which are explicitly outside this patch's stated scope.

6. Audit judgeAgent #1239found 1 low, 4 info

   The review is complete. The findings file holds five merged, reproduced entries. No files outside the findings file and the scratch directory were changed.

   What the patch does correctly. I drove the real patched handler and the parent-commit handler through a scratch harness. The review lane accepts 1 to 16384 and refuses 0, 16385 and non-integers. The default lanes still refuse anything above 8192. Every other validateRequest check still applies on the review lane. The quoted and paid body is byte-identical to the original, the stored hash is the hash of the original body, a mutated replay under the same id returns a conflict, and an identical replay returns the stored response. The constructor rejects limits other than 8192 and 16384. I found no introduced boundary bypass, mutation path or route-isolation break.

   Findings kept, in order of severity:

   • Low, introduced. The agent hard-codes 16384 with no payer readback, and the change note records no deployment order. Reproduced both halves: the parent-commit payer answers the new body with 400 request_refused, and the real agent flow then marks the row uncertain, blocks other reviews for the 800 s window, and terminally fails it with inference_not_reserved on the 404. The id is the input hash, so that proposal cannot be reviewed again. The reverse order is safe. This merges the audit_flow and audit_economics reports. I rated it low rather than medium because no money moves and a correct deployment order avoids it entirely.
   • Info, unchanged mechanism with widened exposure. Credit-lane telemetry reports the sent cap as effective and ignores the provider's adapted-params header. Reproduced on the handler. Whether the live provider adapts above 8192 is unknown because no paid call was made.
   • Info, unchanged limitation. The 600 s provider deadline is not widened with the quadrupled budget. A time-cut review ends failed with its hold retained. Four specialists reported this; merged into one entry, code trace only.
   • Info, unchanged limitation. The 2 USDC ceiling with no quote shrinking now applies to a 16384 quote. Reproduced the clean unpaid refusal on the handler. The affected band is probably unreachable at current prices.
   • Info, trust assumption. The 16384 lane is selected by the idempotency-key pattern alone, so any holder of the inference secret can obtain it. Bounded by the unchanged ceilings.

   Dropped. The audit_permissions report that configuration no longer bounds the review budget describes the patch's stated intent, not a defect.

   Not verifiable from this tree. The request-budget module and the budget module are not mirrored, so I could not confirm that the real quote path accepts 16384 end to end, or the claim that the payer fences a missing id after a 404. Both are stated as unverified inside the findings.

   • lowIntroduced: agent hard-codes a 16384 output cap that an unpatched payer refuses; the ordering dependency is undocumented and each mis-ordered review fails terminally for its input hashintegration/agent-review/network-review-schema.ts:148

     INTRODUCED DEFECT (merged from audit_flow and audit_economics; both reproduced). Before this patch every review body carried max_output_tokens <= 4096, which every payer build accepts.

     The patch makes the agent emit a constant 16384 for every new review while only the patched payer's review lane (createCreditCompletion with maximumOutputTokens:16384, credit-provider.js:39-45) accepts it; the parent-commit handler and the patched default lane both refuse it through validateRequest's output>8192 check (vendor/src/policy.js:17).

     The two mirrors run in separate deployments (integration/agent-review/README.md) and docs/review-output-budget.json records publicationIsActivation:false with no deployment order. If the agent change is live while the payer is at ea60511 (or the payer is later rolled back), the relay answers HTTP 400 {error:'request_refused',payment:'not_signed'} before any reservation.

     In runNetworkReview that body is not in the deferral allowlist (network-review.ts:120-122), so if(!response.ok)throw marks the row 'uncertain'. The uncertain row holds the single-active unique index claus_network_review_active for the 800 s delivery window, so every other submitNetworkReview raises network_review_capacity meanwhile.

     After 800 s networkReviewStatus asks GET /api/requests/:id, receives 404 not_found (no credit, work or x402 row exists) and terminally sets state 'failed', result {error:'inference_not_reserved'} (network-review.ts:160-162).

     Because the review id is nr_ and submitNetworkReview returns the existing row for the same id, that proposal can never be reviewed again without changing its input; the failed row also still counts toward the 8-per-day limit (network-review.ts:66). No money is spent. The reverse order (payer first) is safe: the widened lane still accepts 1..16384, verified with a 4096 body on both handlers.

     Note: the claim that the payer additionally fences the id in claus_payment_ids via confirmAbsent could not be checked because src/budget.js is not mirrored.

     Fix that preserves the intent: make the payer widening a stated precondition of the agent release (deploy and verify the payer lane first and record that order in docs/review-output-budget.json), or have the agent read the lane's maximum from a relay-advertised value (for example in the /api/admission response) and fall back to <= 8192 when it is absent or lower.

     The same 4096 body is accepted (200) by both handlers.

The native credit lane sets telemetry.effectiveMaxOutputTokens to quoted.request.max_output_tokens, i.e. what was sent, and never reads the provider's x-si-adapted-params header, whereas the x402 lane's responseMetadata (vendor/src/response.js:5) does capture that header.

     Until this patch every credit request was at or below the 8192 bound that the vendored validateRequest mirrors; the review lane now sends 16384, above that mirrored bound, and docs/review-output-budget.json records paidModelCalls 0, so no paid call has shown that the provider executes 16384 rather than adapting it.

     If the provider did adapt, the stored result and the agent's failed-review evidence (finish() stores the whole inference result on incomplete_or_invalid_model_result) would state that a 16384 budget was in effect when it was not, misleading the next correction. No spending or verdict integrity is affected: cost comes from x-si-buyer-cost-micro and an incomplete result is still rejected.

     If this matters, read x-si-adapted-params on the credit lane as the x402 lane does, store it in telemetry and derive effectiveMaxOutputTokens from it when present, and confirm one paid call at 16384 before relying on the budget.

     whole finding

     Scratch harness (test/scratch/harness.mjs): patched review lane, 16384 body, stub provider answering HTTP 200 with headers x-request-id, x-si-buyer-cost-micro: 468507 and x-si-adapted-params: max_output_tokens=8192, body {status:'incomplete',usage:{output_tokens:8192,buyer_cost_micro:'468507'},...}.

     Expected: the saved telemetry shows the adapted parameter.

     Actual: the returned/stored telemetry keys are paymentScheme,actualMicroUsdc,latencyMs,requestedMaxOutputTokens,effectiveMaxOutputTokens,requestedInputItems,effectiveInputItems with requestedMaxOutputTokens 16384 and effectiveMaxOutputTokens 16384 and no adapted-params field.

     Whether the live provider adapts above 8192 is unverified; no paid call was made.

   • infoUnchanged limitation: the 600 s provider deadline is not widened with the 4x larger reasoning budget; a time-cut review still ends failed with its 2 USDC hold retainedintegration/payment-review/vendor/src/response.js:12

     UNCHANGED LIMITATION, listed by declared scope ('deadline' unchanged); merged from four specialists (audit_flow, audit_permissions, audit_economics, audit_math). completionTiming(false,'research') still yields providerMs 600000 / activeMs 760000, signal() subtracts a further 30 s (credit-provider.js:89-93), and the agent keeps its 650 s POST timeout and 800 s status window.

     The patch raises the longest legitimate generation from 4096 to 16384 reasoning+output tokens at effort xhigh on inputs of up to ~900 kB canonical evidence without measuring the elapsed time of the failed 4096 call, so the binding limit on a slow review can move from the token cap to the time cap.

     When the local abort fires after startCredit, submitting is true, so finishCredit stores status 'uncertain' with amount null: released = reserved_max - COALESCE(accounted_cost, reserved_max) = 0, and expireCredit later releases nothing for a non-reserved row (credit-work-store.js:39-47, 87-101), so the 2,000,000 microUSDC committed against the lifetime ceiling stays committed until separate reconciliation.

     The agent then records failed/inference_delivery_unknown with paymentHoldRetained:true and never retries, the same outcome as the incident this patch addresses, reached by a different limit. If the provider instead returns x-si-truncated: 1, the cost is kept and the result is marked incomplete (credit-provider.js:171) and parseNetworkDecision rejects it.

     This is the documented behaviour for any timeout; it is reported so the next correction measures the first paid 16384 call's latency instead of treating a timeout as a new bug. If it matters, raise providerMs for the review lane in step with the output budget, keeping activeMs, the relay's 750 s stream maximum and the agent's 650 s fetch timeout consistent.

     whole finding

     Code trace only; not reproduced against the live provider because no paid calls were made.

     State: review lane admitted, reservation and startCredit succeeded.

     Input: a provider generation still running at started + min(600000, activeMs-elapsed-30000) ms (for example 16384 tokens generated at under ~29 tokens/s after the 135k-token prefill of the cause).

     Expected per the patch's goal: a complete JSON verdict.

     Actual: AbortSignal.timeout fires, the catch at credit-provider.js:176-185 saves status 'uncertain', payment 'unknown', amount null; claus_payment_budget.committed stays increased by 2,000,000; after the 800 s window networkReviewStatus (network-review.ts:154-158) sets the review failed with inference_delivery_unknown and paymentHoldRetained true.

   • infoUnchanged limitation: the 2 USDC ceiling with no quote shrinking now applies to a 16384-token quote, narrowing the affordable input range by roughly 58261 microUSDCintegration/payment-review/src/index.js:67

     UNCHANGED LIMITATION, by declared scope ('2-USDC per-call ceiling' and 'no quote shrinking' unchanged); merged from audit_economics and audit_math. The review lane keeps allowSmallerOutput:false, so quoteWithinBudget (vendor/src/quote.js:35) never steps 16384 down to 4096/2048 and validateChallenge throws quote_refused when the unsigned quote exceeds min(pool remaining, caller 2000000).

     From docs/review-output-budget.json (accounted 468507 micro at 4096 output tokens, unsigned quote 526768 at 16384 for the same ~135689-token input) the extra reservation adds about 58261 micro per request, so a review whose 4096-token quote already sat between roughly 1941739 and 2000000 micro would now be refused instead of dispatched.

     The failure is clean and unpaid: outcome credit_quote_rejected, status failed, payment not_signed, accounted_cost 0, no provider call, 502 to the agent; the agent marks the row uncertain and later fails it via /api/requests with verified_nonpayment accounting. Extrapolating the cause's prices to the 900000-byte canonical input cap gives a quote well under 2000000, so the band is probably unreachable with current pricing.

     No change is required; whether review quotes may shrink or the ceiling should scale is a design decision outside this patch.

     whole finding

     Scratch harness (test/scratch/harness.mjs): patched review lane, 16384 body, stub quote endpoint answering 402 with accepts[0].amount '2000001' and caller/pool maximum 2000000.

     Expected per the declared design: refusal without payment.

     Actual: exactly one quote candidate (max_output_tokens 16384) is tried, the handler returns 502 {error:'payment_requires_reconciliation',id} and the stored work row is status 'failed', accounted_cost '0', outcome {rail:'surplus_credit',failure:'credit_quote_rejected',payment:'not_signed'}.

     The real price table is not mirrored, so the exact input size at which this triggers cannot be computed from this tree.

   • infoUnchanged trust assumption, widened: the 16384 lane is selected by the caller-chosen Idempotency-Key pattern alone, so any INFERENCE_SECRET holder can obtain the widened budgetintegration/payment-review/src/index.js:68

     TRUST ASSUMPTION, not a monetary bypass (from audit_permissions; reproduced on the handler). workHandler picks reviewCredit purely from the idempotency key matching network-review:nr_<64 hex>; createCreditCompletion never inspects the id and nothing on the relay checks that such an id corresponds to a persisted claus_network_reviews row or that the body is a review request.

     This routing predates the patch; what the patch adds is that the pattern now also grants a 16384 output budget that no other caller of the same INFERENCE_SECRET can obtain (the default lanes refuse 8193+). The agent's Builder flows and the review flow share INFERENCE_SECRET (relay() in network-review.ts), so any process holding it can mint a review-shaped id.

     Exposure stays bounded by the unchanged 2 USDC quote ceiling, the single active work slot and the lifetime ceiling, so this is a boundary to document rather than a defect to fix in this patch. If a tighter boundary is wanted, bind the widened cap to evidence only the agent produces (for example require the review body's instructions to carry the fixed review preamble, or have the agent sign the id), which is a design decision outside this patch's scope.

     whole finding

     Scratch harness (test/scratch/harness.mjs): the patched handler built as index.js builds reviewCredit (maximumOutputTokens:16384) accepts a 16384 body under Idempotency-Key network-review:nr_aaaa...(64 hex) with instructions 'review' and a one-item input, reserves, quotes and dispatches it (200); the same body under a build_<24 hex>:model:1 id on the default handler is refused with 400 request_refused.

     In index.js:141 and :158 the only selector between the two handlers is the regex at line 68; no persisted review or body shape is consulted.

     Reproduced in the handler harness, not against a running relay.
