fix(responses): settle a credential hop where the replay is dispatched (#4709) - #4745
Conversation
#4709) [skip ci] A credential hop books the replay it is about to make, and the reservation is the charge. The layer that then dispatches that replay has accounting of its own, so the same physical send was charged twice. Two shapes produced it. A retry-helper replay reports every physical send back through onSendsConsumed, and the adapter hop sites did not mark the reservation countedExternally, so the reporter added a second charge. An adapter that owns its transport -- Kiro's reset ladder, Cursor's transport ladder -- reserves once per physical send against the same budget, so it charged the hop's replay again no matter what the hop did. The visible effect is worse than a miscount. Once the base allowance is spent, a recovery class may still draw the single shared final-recovery reserve; a doubled charge spends it early, and the ladder answers a provider 429 with a synthetic error instead of the rate limit it was recovering from. The settlement now follows the dispatcher rather than the ladder: - A helper-routed replay reserves with countedExternally, so the reporter's first send settles the booking instead of adding to it. - An adapter-owned ladder receives adapterDispatchBudget, a live delegating view of the same budget that spends a permit handed down through pendingHopPermit on the adapter's first reservation. Every later send in that ladder is a new physical send and is charged normally. - SingleUseDispatchPermit.assumeCharge() is what closes an externally counted booking when the holder is the layer that sends. Leaving it open is not harmless: the next report of the request would settle against it and one real send would go uncharged. adapter-dispatch.ts keeps confirming at the dispatch boundary, and skips that confirmation when the adapter owns dispatch -- settling first would hand the adapter a dead permit, which it reads as an exhausted request and stops sending on. adapter-continuation.ts still never confirms, because its replay is the next loop iteration. run-turn-execution.ts always hands the reservation down, because a runTurn adapter is by definition the layer that sends. The view delegates through getters rather than copying. A spread would freeze used, reserveSpent and the target counters at construction time and hand the adapter a budget that can never read as exhausted.

리뷰 · 우선순위 76 / 80이 PR은 이슈 #4709가 말한 회계 버그의 남은 반쪽을 고친다. generic-OAuth 429 홉은 예약을 잡는 순간이 곧 청구인데, 그 재전송을 실제로 내보내는 층(재시도 헬퍼의 onSendsConsumed 보고, 또는 Kiro/Cursor처럼 어댑터가 자기 사다리에서 reserveDispatch 하는 경로)가 또 한 번 청구해서, 물리 전송 1회가 예산에서 2회로 잡혔다. 기본 허용량이 바닥나면 공유 final-recovery 예비분이 빨리 소모되고, 진짜 429를 살리려던 사다리가 합성 오류로 끊길 수 있다. 현재 dev HEAD 핵심은 세 갈래다. (1) 헬퍼가 재전송을 보고하는 경우 reserveCredentialHop에 countedExternally를 켜 기자(reporter)의 첫 보고가 예약을 정산하게 한다. (2) 어댑터가 전송을 소유하면 adapterDispatchBudget 라이브 위임 뷰와 pendingHopPermit으로 첫 reserveDispatch가 홉 예약을 쓰게 하고, SingleUseDispatchPermit.assumeCharge()로 외부 부킹을 닫는다. (3) adapter-dispatch.ts는 어댑터 소유일 때 dispatch 경계에서 permit.use()를 건너뛰고, adapter-continuation.ts는 다음 루프 iteration이 재전송이므로 확인하지 않으며, run-turn-execution.ts는 항상 예약을 아래로 넘긴다. 뷰는 스프레드 복사가 아니라 getter로 used / remainingBaseSends를 살아 있게 읽는다. 스프레드면 생성 시점 값이 얼어 #4546이 없앤 ‘층마다 새 허용량’ 부류의 결함이 된다. 문서 라인 메인테이너의 판단이 필요한 지점

When generic OAuth rotation uses an adapter that exposes fetchResponse but does not reserve ctx.sendBudget—such as the Command Code and Google adapters—this predicate is true, so the replay skips hop.permit.use(). If the adapter reaches the wire and then throws, rebuildAndRefetch returns its failure and the caller releases the still-open permit, removing that physical attempt from the shared budget; a subsequent combo or fallback leg can therefore exceed the request send ceiling. Detect actual budget-reserving adapters rather than treating every fetchResponse implementation as owning a reservation ladder.

…4707) [skip ci] The #4546 work added a durable spend-reservation ledger so token, identity and pool ceilings survive a restart, and nothing in production reached it. The only call to admitWorkflowTurn() omitted its spend argument, so sharedSpendLedger() was never constructed, spend-ledger.jsonl was never created by ordinary traffic, and markDispatched, settle and abandon had no production caller at all. The ceilings the feature advertised stayed process-local and count-only. request-spend.ts is that caller. It books by observing the request's own send counter rather than by being called from each dispatch site: that counter moves exactly once per physical send -- a reservation increments it, a refund decrements it, and an externally reported send settles against a booking already counted -- so one entry per increment is one entry per send. A dispatch path added later cannot forget to book, which is the failure mode that produced an uncalled feature the first time. The observer may refuse. A ledger limit that could only describe a send after the fact would be no ceiling at all, so reserveDispatch consults it last, after every cheaper bound has passed, and a refusal denies the dispatch as spend-exhausted. Consulting it last matters because it is the only bound here that writes: an entry booked for a dispatch some other check would have refused is spend the request never makes, held against the scope until retention expires. A booking is confirmed dispatched only once a later send exists, because that later send proves the earlier one left. The newest stays open, so a reservation the budget hands back is still released for free. The cost is bounded and stated: a hard crash between reserving and sending replays as abandoned rather than unresolved, for at most one send per request. Settlement follows what the request learned. addFinalRequestLog is the one seam every request passes exactly once, whatever transport served it and however it ended, and the terminal usage is already known there. That usage belongs to the last send that left, so it settles with the real figure; every earlier send failed without reporting usage of its own and may still have been billed, so it becomes unresolved spend rather than free. A request that reports no usage at all -- a cancel, a lost stream -- leaves all of them unresolved. The ledger also now resolves what replay leaves behind. A reservation that survives restart has no owner: nothing in the new process can settle it, and leaving it live holds its tokens against the scope forever, which is a ceiling that only ever tightens. Deleting the entry is not the alternative, because that would hand the same send id a second reservation. An undispatched reservation never reached the wire and is abandoned; a dispatched one may already have been billed and becomes unresolved. Both are journaled, so a second restart has nothing left to redo. The reservation uses the caller's max_output_tokens as its output ceiling, captured in request-prepare before any body exists. A caller that omits it leaves the provider/model default in charge and reserves only the input estimate; settlement then books the real figure, so the gap is a looser bound up front rather than a wrong one after. The identity scope is the privacy-safe account label the request log already uses, and the ledger aliases it again on the way to disk, so no raw credential reaches either. The default policy still sets no token ceiling on any scope, so an unconfigured install accounts and reports without refusing anything. The operator configuration path for those limits is deliberately not in this change. Closes #4707

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep the handed-down hop refundable until the adapter commits the send.
adapterDispatchBudgetView.reserveDispatch calls hopPermit.assumeCharge() at src/server/responses/request-send-budget.ts:233, then returns a permit whose release() is a no-op. This settles the original hop before the adapter commits a wire send.
runCursorTurnWithRetry reserves and uses the permit before transport.run() at src/adapters/cursor/transport-retry.ts:111-124. Its catch path explicitly retries when requestUncommitted(transport) is true. That is a pre-commit failure, but the loop does not release the handed-down hop before taking a new reservation. The first hop therefore remains charged and can exhaust the request budget.
Deferring assumeCharge() only until the delegated permit's current use() call is not sufficient because the adapter calls use() before transport.run(). Keep the source permit open through the pre-commit phase, release it when requestUncommitted(transport) or another pre-wire setup failure abandons the dispatch, and settle it only after the adapter reaches its commit boundary. Add regression coverage for both delegated release() and a Cursor pre-commit retry.

) [skip ci] When a request exhausts its shared send budget the three dispatch paths disagreed about what the client was told. Passthrough returned 429 and explicitly declined to blame the provider. The adapter paths did not special case SendBudgetExhaustedError: they fell through describeUpstreamConnectFailure and answered 502 "Provider unreachable" for a refusal this process made itself. The runTurn path pushed an unstructured error event, which is inferred back to 502 and delivered under HTTP 200. The status is the load-bearing half, and it is worse than a mislabel. The Codex client retries 5xx and does not retry a direct 429, so telling it the provider broke makes it send the whole turn again -- the amplification this budget exists to stop. Reporting the refusal as a quota code would stop the client for a reason that is not true, and the retryable streaming rate-limit codes would restart the stream, so neither is available. Both adapter catch sites now answer 429 before describeUpstreamConnectFailure can launder the refusal, and runTurn emits it as a structured terminal event with its status, type and code on the event itself, because an unstructured message is inferred back to 502. classifyError keeps the distinct code by matching the supplied type rather than the status. An upstream 429 still classifies as rate_limit_exceeded; only this proxy's own refusal carries request_send_budget_exhausted. Before this the passthrough path asked for that code and the classifier overwrote it, so even the one path that got the status right could not be told apart afterwards. A local 429 must also not look like a provider one to our own routing. rotateRunTurnAdapterOnPreflight429 returns early on the code, before it reads the status, so a refusal cannot rotate a credential or write a cooldown against an account that rate-limited nothing -- a fake quota signal that outlives the request and misroutes later ones. The terminal-guard continuation loop never consulted sendBudgetExhausted() while the main recovery loop did, so a spent budget could still same-key 429-replay on a live stream. It is checked before the wait cancels the upstream body, so a refusal keeps the real 429 with its Retry-After and quota evidence intact. Upstream classification of a provider 429 as org or project spend exhaustion is a separate contract and is not touched here. Closes #4708
…4546) [skip ci] Carried from PR #4717. The Command Code reasoning-effort retry commit is left behind: that retry stays on the same selected key, so it is not needed to tell account A's usage from account B's, and keeping it out keeps this layer reviewable. The injected-executor fix it depended on is already here. Adds the consumer-side assertion the attribution depends on. A row carries BOTH the per-attempt records and the request total, and a reader that added them would report 600 input tokens for 300 that were actually spent. usageAttributions takes the attempts when a row has them and the entry row only when it has none, so the parent total is a fallback for rows written before attempts existed rather than another column to sum. That arithmetic is also why hidden attempts must not be folded into the response the client sees: the Codex client treats response.completed.usage as the exact usage for that response and adds it to its durable turn and thread totals, so a proxy-side sum would corrupt accounting it owns. Closes #4717 Co-authored-by: thisisjun786 <259586770+thisisjun786@users.noreply.github.com>
…later (#4546) [skip ci] The transient-hold resolver and the pool-wide recovery limiter added in #4626 still have no production caller, so #4701 is not closed here. Wiring them turned up a defect in the thing being wired, and that has to be fixed first. A withheld dispatch promises the caller a retry time. It was computed from the probe pacing alone. When the RATIO limiter is what refused, the account usually has no probe state at all -- nothing was ever granted for it -- so nextProbeAt returned now, and the refusal told the caller to try again immediately. A withheld dispatch that busy-loops puts the same load on an already-failing pool as the dispatch it refused, which is the opposite of what the limiter is for. It also violates the Retry-After half of #4701's completion criteria directly. The limiter is the only thing that knows when its own window moves, so it now says: nextRecoveryAt returns now while the allowance is unspent, and otherwise the moment the oldest bucket still inside the window falls out. Every such bucket started after now - windowMs, so the answer is always strictly in the future, and it is a real change point rather than a guessed delay. The withheld result takes the later of that and the probe pacing. The existing zero-allowance test asserted only that the result was withheld, which is why the defect survived the unit suite that was written to cover this module. It now asserts the time as well. Refs #4701
…#4546) Each layer of this lane closes one seam of the #4546 amplification: the credential hop that was charged twice, the spend ledger with no caller, the refusal reported as a provider fault, the usage attributed to the wrong key, the withheld recovery that said "retry now". What none of them checks is whether the seams agree with each other. This composes the real primitives -- the request execution budget, the durable spend ledger with its request-scoped caller, the pool recovery limiter -- and asserts that the numbers describe the same events: physical sends, budget consumption, ledger reservation and settlement, and the refusal the caller is given. The scenarios are the incident's own: a request whose every layer tries to recover, concurrent requests contending for one process-wide recovery allowance, a caller that keeps its detour instead of adding a second trial to a failing account, a fan-out child spending the parent's allowance rather than a fresh one, and a restart that must neither reset a ceiling nor settle the same send twice. A fixture that only counted sends would have passed throughout the incident, which is why every case ties a send count to the spend the ledger recorded for it.
The account-change scenario the incident needs, written against current behaviour because the #4710 refusal is owned by another lane and is not in this stack yet. What it pins now: continuation state is dropped and the turn continues, an uploaded file reference is classified non-portable and is NOT removed by the scrub, and the carriers must be read directly because the portability verdict reports only the first reason it finds -- a body carrying both a response id and a file reports the response id. What it documents: once the refusal lands, that body must be declined before dispatch and the refusal must win over the response id. The two properties above are what the change has to preserve, so they are asserted now. Also pins the accounting invariant that refusal owes: a decision made before dispatch spends no send and books no ledger entry. A refusal counted as a send would appear as provider load that never happened and would push a healthy account toward a cooldown.
…fusing sends (#4546) Four fixes, batched into one push so the queue only pays once. 1. src/server/responses/core.ts was 214 lines against a 210-line cap in tests/fixtures/file-size-baseline.json. The spend-observer wiring added four lines of comment and continuation. The comment is now one line and the expression one line, and the file is back at its cap. The ratchet only ever lowers caps, so growing past one is a hard failure rather than a nudge. 2. The spend tracker refused a dispatch on ANY ledger denial. Only an operator's configured ceiling should: capacity, durability and a journal this process could not prove complete all mean the ledger cannot ACCOUNT for the send, which is not a reason to refuse one. An unconfigured install keeps the count caps it already had and is not newly refused, and a degraded ledger must not become an outage. 3. The shared ledger is now resolved on the first charge rather than when the request is built. It opens a journal under the OpenCodex home, and a request that never dispatches has no business creating one; this also means the home in effect at dispatch is the one written to, instead of whichever home was current when the first request of the process happened to be constructed. 4. Three assertions in the new tests claimed states the code never reaches. The concurrent-probe case asserted a limiter refusal, but the second caller short-circuits on the lease before it reaches the limiter and costs no allowance; the shared bound is now proved by asking the limiter directly. The exhausted-ceiling case asserted final-recovery-spent where the total ceiling refuses first, so it asserts total-exhausted and checks reserveSpent separately for the point it was making. The unstructured-error control asserted an exact 502 where the property that matters is that the identity is gone, so it asserts that instead. Tests are not typechecked -- tsconfig includes only src -- so a test that asserts the opposite of what it claims passes silently. These were found by reading, not by running.
Two source-of-truth failures from the previous tip run, both mine. tests/lib/transient-budget-scope-source.test.ts pinned the exact core.ts line that mints the request's send budget, and bl2 changed it to install the spend observer. The oracle now matches the new shape and additionally asserts the observer is attached at the same place, which is the property that actually matters: a combo child inherits the parent's holder and must not open a second set of ledger entries for the same physical sends. tests/lib/spend-reservation-ledger.test.ts caught a real defect in the replay reconciliation, not a stale expectation. An exhausted scope must still be exhausted after a restart -- that is the whole reason the ledger is on disk -- and abandoning a replayed undispatched reservation handed its tokens back and reset the ceiling. The distinction I drew was wrong. "Open" does not prove nothing was sent: the torn-tail rule immediately above says the journal may be missing its last record, so a send can dispatch and die before its dispatch record lands. Both live states now resolve to unresolved spend, which is the conservative answer and the one that preserves the ceiling. The bl2 wiring test asserted the old split and is updated to the new figures, along with the structure contract and the tracker's own comment.

Summary
A credential hop books the replay it is about to make, and the reservation is the charge. The layer that then dispatches that replay has accounting of its own, so one physical send was charged to the request budget twice.
Two shapes produced it. A retry-helper replay reports every physical send back through
onSendsConsumed, and the three adapter hop sites did not mark their reservationcountedExternally, so the reporter added a second charge. An adapter that owns its transport — Kiro's reset ladder (src/adapters/kiro-retry.ts), Cursor's transport ladder (src/adapters/cursor/transport-retry.ts) — reserves once per physical send against the same budget, so it charged the hop's replay again regardless of what the hop did.The visible effect is worse than a miscount. Once the base allowance is spent a recovery class may still draw the single shared final-recovery reserve; a doubled charge spends that reserve early, and the ladder answers a provider 429 with a synthetic error instead of the rate limit it was recovering from.
Settlement now follows the dispatcher rather than the ladder:
countedExternally, so the reporter's first send settles the booking instead of adding to it.adapterDispatchBudget, a live delegating view of the same budget that spends a permit handed down throughpendingHopPermiton the adapter's first reservation. Every later send in that ladder is a new physical send and is charged normally.SingleUseDispatchPermit.assumeCharge()closes an externally counted booking when its holder is the layer that sends. Leaving it open is not harmless: the next report of the request would settle against it and one real send would go uncharged.adapter-dispatch.tskeeps confirming at the dispatch boundary introduced by #4690, and skips that confirmation when the adapter owns dispatch — settling first would hand the adapter a dead permit, which it reads as an exhausted request and stops sending on.adapter-continuation.tsstill never confirms, because its replay is the next loop iteration.run-turn-execution.tsalways hands the reservation down, because a runTurn adapter is by definition the layer that sends.The view delegates through getters rather than copying. A spread would freeze
used,reserveSpentand the target counters at construction time and hand the adapter a budget that can never read as exhausted — the same class of defect as the fresh per-layer allowances #4546 removed.This finishes the remaining half of the accounting story that #4621 opened; that PR's review identified the adapter-internal double reservation, and its author is credited with a

reserveCredentialHopcall site and the dispatcher each one's replay reaches:adapter-dispatch.ts(adapterfetchResponseor the retry-helper refetch),adapter-continuation.ts(same two shapes),run-turn-execution.ts(adapter-owned only),sidecar-execution.tsandpassthrough-dispatch.ts(unchanged — the sidecar loop dispatches directly and reports nothing, so itsuse()remains correct, and the passthrough ladder already had thecountedExternally+pendingHopPermitshape this change generalises).kiro-retry.tsandcursor/transport-retry.tsboth callsendBudget.reserveDispatchper physical send and throwSendBudgetExhaustedErrorwhenuse()fails, which is why the view falls back to a real reservation instead of returning a settled permit.fetchWithResetRetry/fetchWithTransientRetryreporting: only the transient layer reports throughonSendsConsumed, and the inner reset layer is deliberately suppressed, socountedExternallyis set only when a transient policy exists.sendBudget: adapterSendBudgetcall site;adapterSendBudgetstays exported becausetests/responses/responses-core-modules.test.tsasserts holder identity through it.tests/lib/execution-budget-permits.test.tsthat pinned the previous literalrebuildAndRefetch("oauth-account-429", () => { hop.permit?.use(); })call shape, and re-read the neighbouring oracles intests/lib/transient-budget-scope-source.test.ts(sixreserveCredentialHop(sites, thependingHopPermit = hop.permit;assertion, the release count) to confirm this change keeps them true.structure/transports/responses.md, which owns this contract, so the documented ladder shapes match the code.Regression coverage added:
tests/lib/execution-budget-permits.test.ts— behavioural: an external reporter settles acountedExternallybooking rather than charging again;assumeCharge()takes the booking over, keeps the send charged exactly once, closes the booking so a later report is charged in full, and refuses a second confirmation or a refund. Plus source oracles for all three hop sites.tests/responses/responses-core-modules.test.ts— the adapter view spends a handed-down hop on its first reservation, charges the second reservation normally, clearspendingHopPermit, and readsused/remainingBaseSendslive from the delegated holder.Hosted CI: this branch is a non-tip layer of a stacked lane and carries
[skip ci]under the maintainer-approved DEV-STACK-08 tip-only CI policy. The lane's CI gate runs on the tip branch.Checklist
