A brief cooldown on a preferred target routes straight to whatever comes next in the list — including a target the operator only ever wanted used in an emergency. There is no way to say "this one is a last resort", so transient cooldown state dispatches it. `cooldownWaitPolicy: "before-last-resort"` plus `lastResort: true` on a target makes selection try the normal targets first. If they are only cooling and the earliest cooldown expires inside the combo's existing `waitForCooldownMs` budget, the request waits for that instead of dispatching the last resort. **The policy only ever defers, and that is the property the tests are built around.** When no normal target can be reached — every one cooling past the budget, already attempted, or ruled out by the caller — the last-resort target is dispatched exactly as today. A policy that could withhold it would turn a fallback into an outage, which is strictly worse than the premature routing it prevents. Five tests cover that one way each: cooling past the budget, excluded, ruled out by the caller's own predicate, a combo whose targets are all last-resort, and a zero wait budget. The deferral wait is scoped to normal targets. A short cooldown on the last-resort target must not make the request sleep on behalf of the very target the policy is avoiding — though the ordinary wait below the policy branch may still wait for it, and should, once it is the only candidate left. The test asserts which branch does the waiting rather than whether any wait happens. Both fields are omitted by default and only the exact literal `before-last-resort` opts in, matching the rule `reasoningEffortMode` already follows. A truthy non-boolean `lastResort` normalizes to false, so a config that fails validation cannot still change routing if it is loaded anyway. The normalizer's null is dropped by `sparseComboConfig`, so stored combos do not gain a meaningless key. Scoped to src/combos/resolve.ts, which #5716 does not touch — that PR changes cooldown *duration* in failover.ts, this one changes *selection*. They merge in either order. Eight mutations, seven caught, including the safety one: withholding the last resort when no normal target is reachable fails immediately. The survivor is an equivalent mutant — the `targets.some(t => !t.lastResort)` guard is a short-circuit that only avoids one wasted selection pass, since the fall-through already handles an all-last-resort combo identically. Recorded rather than papered over with a contrived assertion. Closes #5691 (cherry picked from commit a1ab7f3)
Four findings from the review on #5736, all reproduced before changing anything. **The deferral wait and the ordinary wait now share one budget.** The worst of the four and a bug I introduced. `waitForCooldownMs` is documented as a cap per *selection attempt*, but the fall-through kept the original clock and the full budget, so a 3s deferral followed by a 9s ordinary wait spent 12s against a 10s cap — close to double in the worst case. Both the remaining budget and the clock now advance by whatever the deferral slept, and they are identical to the old values when it did not, so the non-policy path is untouched. The clock half needs its own test: sharing the budget alone still measures the second wait from the original `now`, so a target whose cooldown lapses during the deferral reads as cooling for longer than it is. Pinned by asserting the second sleep is 500ms rather than 3,500ms. **`lastResort: false` is no longer persisted.** The normalizer gives every target an explicit `false`, and the management route wrote normalized targets straight into stored config — so saving any combo added a noise key to every target, including combos that never use the policy. Only the opt-in value is stored now, matching how the combo-level policy is already handled by `sparseComboConfig`. **An omitted policy no longer deletes the stored one.** The management route preserves `cooldownMs`, `waitForCooldownMs` and `defaultEffortMode` when a request omits them; `cooldownWaitPolicy` was missing from that list, so a GUI round-trip would have dropped it. `lastResort` rides on each target and had the same problem, so it is carried over per target, matched on provider and model. **Docs.** The English config table gained rows for both keys, and the four translated guides that carry that table (ja, ko, ru, zh-cn) gained the same two rows. Those translations are mine and should be checked by a native speaker. Two mutations added for the budget fix — not counting the deferral sleep, and not advancing the clock — and both are caught. The re-anchored safety mutation still fails immediately. (cherry picked from commit a57f419) Co-authored-by: Abhishek Sharma <abhicse24@gmail.com>
The carried #5736 test matched no layout seed, so tests/test-layout.test.ts failed on it. Register it in codex-integration in both layout files. Co-authored-by: Abhishek Sharma <abhicse24@gmail.com>
A whole-combo PUT that omitted reasoningEffortMode or imageInput reset them to strict/auto. `ocx combo set` has no flag for reasoningEffortMode, so every CLI edit silently turned an adaptive combo back to strict. The route now carries both from the stored combo when the body omits them, like it already does for cooldownMs, waitForCooldownMs, defaultEffortMode and the last-resort policy. Explicit values still replace them and invalid values are still rejected. The dashboard used omission to mean the default, so toPutBody now sends both fields explicitly; otherwise switching back to auto or strict there would never take effect. Storage stays sparse because the route strips defaults before persisting. Closes #5687
… the config reference The configuration reference still said every combo cooldown is capped at ten minutes and did not list lastResort or cooldownWaitPolicy. It now states the 24-hour cap on explicit Retry-After delays, documents both new fields, and the guide says the policy needs a nonzero waitForCooldownMs.
A dashboard-shaped save re-sends targets without lastResort and omits the combo policy. Pin that both survive it and a rename, that a swapped-in target does not inherit the flag, and that explicit false/null clear them without leaving keys in the stored config.

This policy runs only through pickComboTargetWithWait, but after an upstream failure executeComboResponses first calls advanceComboAfterFailure, which performs a synchronous unrestricted pick and uses it immediately when non-null. For example, with normal targets A and B, last-resort C, and B cooling for 3 seconds, a failure from A causes that selector to choose C immediately even when waitForCooldownMs is 10 seconds; the new policy never gets a chance to wait for B. Route post-failure selection through the policy-aware path, or exclude last-resort targets from the immediate pick when a waitable normal target remains.

When updating an existing combo, any array-valued targets enters this preservation map before comboConfigError validates its elements. A malformed request such as targets: [null] therefore calls Object.hasOwn(null, "lastResort") and throws instead of returning the existing structured 400 validation response. Check that each target is a plain record before inspecting it, or run validation before performing the carry-over.

Apply before-last-resort only when a wait budget exists.
At src/combos/resolve.ts:403-413, the normalOnly selection runs whenever cooldownWaitPolicy is "before-last-resort". It excludes every lastResort target before the code checks options.waitForCooldownMs.
With strategy: "round-robin", a healthy normal target makes pickComboTarget return immediately. The healthy lastResort target therefore does not participate in rotation, even when waitForCooldownMs is 0.
This conflicts with the public contract in docs-site/src/content/docs/reference/configuration/routing.md:93 and docs-site/src/content/docs/guides/combos.md:259-263. Those documents state that the policy applies while a normal target is cooling and that zero wait performs no deferral. The implementation comment at src/combos/resolve.ts:394-401 describes the intended emergency-only behavior, but it does not override those published contracts.
Suggested fix
const defersLastResort = policyCombo?.cooldownWaitPolicy === "before-last-resort"
+ && options.waitForCooldownMs > 0
&& policyCombo.targets.some(target => !target.lastResort);Add a round-robin regression case with healthy normal and last-resort targets and zero wait.

Mark the local budget refusal as non-retryable for SDK clients.
When the first reservation is denied, src/server/responses/core-combo.ts:457 returns a local 429 without x-should-retry: false. formatErrorResponse adds that header only for replay-refusal codes, not request_send_budget_exhausted. Supported SDK clients can retry the bare 429 and submit the request again as a new logical request with a new send budget. Set the no-retry header on this response and assert it in the first-reservation test.

After an upstream failure, core-combo first takes a synchronous pick from advanceComboAfterFailure, which ignored cooldownWaitPolicy. With normal A and B, last-resort C and B cooling briefly, a failure on A dispatched C at once and the policy never waited for B. Under the policy that pick now skips last-resort targets; a null result falls through to pickComboTargetWithWait, which waits for a normal target inside the budget or dispatches the last resort. Also pin that a last-resort target stays out of round-robin while a normal target is available. Co-authored-by: Abhishek Sharma <abhicse24@gmail.com>
The per-target lastResort carry-over read every target before validation, so targets: [null] threw instead of returning the structured 400, and an untrimmed re-sent target missed the stored (trimmed) one and lost its flag. Skip non-record entries and match on trimmed provider and model. Co-authored-by: Abhishek Sharma <abhicse24@gmail.com>
…e policy With cooldownWaitPolicy set, a lastResort target is skipped whenever any normal target is available, for every strategy; waitForCooldownMs only adds the wait for a cooling normal target. Replace the sentence that said the policy needs a nonzero wait, and state the rule in the English reference and in the translated table rows.

When a translated Chat request arrives while its normal target is briefly cooling, this path makes the final Responses executor wait for that target, but the earlier routeModel preflight still calls tryPickComboModel → pickComboTarget without this policy and selects the immediately available last-resort target. chat-completions.ts then performs admission checks and target-specific effort normalization against that wrong target, so a scoped key that permits the normal target but not the emergency target receives a 403 instead of waiting, and an emergency target with an empty effort ladder can strip effort before the normal target is dispatched. Make the synchronous preflight use the same last-resort decision, or defer concrete-target checks and normalization until executeComboResponses makes the authoritative pick.

Explicit server delays are now capped at 24 hours (MAX_SERVER_DELAY_MS), while reset-derived, configured and fallback cooldowns keep their 10-minute ceiling. The combo guide in all eight locales and the configuration reference state the two ceilings.lastResort, andcooldownWaitPolicy: "before-last-resort"makes selection wait out a short cooldown on a normal target (withinwaitForCooldownMs) instead of jumping straight to the emergency target. The policy only defers: when no normal target is reachable the last resort is dispatched as before. Separately,PUT /api/combosused to resetreasoningEffortModeandimageInputwhenever a body omitted them, so everyocx combo setsilently turned anadaptivecombo back tostrict. Omitted values are now kept from the stored combo, likecooldownMs,waitForCooldownMs,defaultEffortModeand the last-resort fields already were. Explicit values still replace them and invalid values are still rejected. Because the dashboard used omission to mean the default, its save payload (toPutBodyingui/src/combo-workspace-data.ts) now sends both fields explicitly, so switching back toauto/strictin the dashboard still takes effect. Storage stays sparse because the route drops defaults before persisting. No dashboard screen changes.Carries #5717

Security review
Item 1 changes a tool-authorization boundary: which upstream tool calls the proxy relays to a client that will execute them.
bridgeToResponsesSSEandbuildResponseJSONnow refuse a client tool call whenenforceDeclaredToolNames === trueanddeclaredToolNamesis absent. The predicate is(enforce === true || declared != null) && enforce !== false && !declared?.has(name), so it only removes the fail-open case and never widens what is relayed.adapter-delivery.tsandrun-turn-execution.tspassdeclaredToolNamesfrombuildToolBridgeMaps, which is always aSet, so the live Responses path already enforced. The fix closes the helper-level fail-open for any caller that asks for enforcement without supplying a catalog.src/server/responses/passthrough-dispatch.tsnever calls the bridge. Its guard (undeclaredToolGuardActive) is derived only from the catalog it captured (declared names, nameless client call types, or an explicit clienttoolskey), and it has no enforce flag separate from that catalog, so the "enforcement requested, catalog missing" state cannot occur there.tests/responses/responses-tool-conformance.test.tscovers absent, null, empty, mismatched and matching catalogs, the explicitly disabled scope and the unscoped null catalog, for both SSE and JSON, including the nested refusal message and wire error type/code.tests/responses/responses-undeclared-tool-guard.test.tsandtests/responses/chat-completions-deferred-tools.test.tsstay green.Maintainer security review is still required before merge.
Notes for review
Co-authored-bytrailer. Upstream PRs fix(bridge): require a catalog for enforced client tool calls #5717, fix(combo): refuse first dispatch when send budget is exhausted #5715 and fix(combo): bound server Retry-After target cooldowns #5716 were 10 commits behinddev, so they were cherry-picked by SHA. The only textual conflict was the Korean combo guide, where fix(combo): refuse first dispatch when send budget is exhausted #5715 and fix(combo): bound server Retry-After target cooldowns #5716 edit neighbouring paragraphs; both were kept.tests/codex-integration/combo-last-resort.test.tsmatched no test-layout seed, so it is now registered inscripts/test-layout/layout.jsonandtests/fixtures/test-layout-expected.json.context_length_exceededenvelope the loop's natural end produces. The carried test pins this.ocx combo sethas noreasoningEffortModeflag. It used to reset the field silently; now it preserves it. Clearing remains available from the dashboard or with an explicit API value.advanceComboAfterFailure) ignoredcooldownWaitPolicy, so a failure on a normal target could dispatch the last resort while another normal target was only briefly cooling. Under the policy it now skips last-resort targets and hands a null result to the policy-awarepickComboTargetWithWait. That function's onlysrccaller (core-combo.ts) already falls back to that path on null.lastResortcarry-over on PUT threw ontargets: [null]instead of returning the structured 400, and it missed a re-sent target with untrimmed provider/model.lastResorttarget is emergency-only for every strategy. It stays out of round-robin/random rotation while any normal target is available, andwaitForCooldownMsonly adds the wait for a cooling normal target. A test pins the round-robin behavior.x-should-retry: falseto the combo's localrequest_send_budget_exhausted429. The single-target path (adapter-dispatch.ts) returns the same bare 429 by design because Codex does not retry a 429, so any header change should cover both paths in its own PR.defaultEffortstill resets it tonull, and for adefaultEffortMode: "force"combo the CLI body is then refused. This PR does not change that.Verification

They are in service ownership, launcher shutdown, the native Codex/Grok toggles, package-tree integrity, the remote-workspace sandbox and the star prompt. These were run at this exact head from a checkout outside~/.codex, because inside a Codex-managed worktree the test-home guard refuses to delete temp directories and adds about 900 location-only failures. The ten failing files (all exceptshutdown-launcher, whose signal tests kill the calling shell) were then run in isolation at both cleandev742ee16 and this head.
