When a model-detour affinity becomes transiently blocked before a detour account has been recorded, previewReusableAffinityAccount returns null, so previewCodexAccountForRequest can fall through to the ordinary thread affinity, while this new resolve branch immediately calls pickAlternateCodexAccount for the model-detour lane. For example, after a model roster expands to include the ordinary account, preview can report that ordinary account while quota or round-robin resolution selects another eligible account; subagent fallback then scores a different account from the one that serves the request. Make the model-detour preview compute the same side-effect-free alternate (for example via the strategy's peek operation), or make resolution follow the same fallback order, and add a focused preview/resolve regression test.

resetFirstAffinityReplacementpasses candidates accepted byhasCodexQuotaHeadroom()topickResetFirstCodexAccount().hasCodexQuotaHeadroom()returnstrueforCODEX_UNKNOWN_USAGE_SCORE, while reset-first selection orders candidates by reset time and does not compare them with the bound account's usage.

Correct the French preemption wording.
The English passage states that preemption moves an unbound request up when a higher-priority tier regains quota headroom. une demande non liée augmente says that the request increases, not that its priority changes.
Use la préemption fait remonter une demande non liée dès qu'un ordre supérieur retrouve de la marge.

Correct the French manual-pin semantics.
This line says an accepted write “publie” a manual pin, which reads as creating a pin. The documented behavior is the opposite: an accepted priority write clears the manual pin while retaining the selected account. Rewrite this sentence to state the pin-clearing behavior.

Document the complete transient-failure state machine across the affected pages.
The new affinity text describes permanent rebinding, but it does not consistently document the separate transient-detour path: serve the current request on another account, preserve the home binding, return when the home account recovers, and release the binding only after the 10-minute hold limit.
As per path instructions, update all directly affected pages when a user workflow changes.

Include the strict lower-usage requirement in both German strings.
The routing contract requires a replacement account to have quota headroom and strictly lower usage. The strings at Lines 1402 and 1456 mention free quota but omit the lower-usage condition.
The reference configuration at docs-site/src/content/docs/zh-tw/reference/configuration/providers.md:37-39,142 states both conditions. Add the equivalent of “with strictly lower usage” to both German translations.

Include the lower-usage headroom trigger in both descriptions.
Both strings say that a bound task rebinds only when its current account cannot serve. The routing policy also permits rebinding when a destination has genuine quota headroom and strictly lower usage. Without that condition, the GUI states that healthy bound tasks never rebind.
Update both entries. Keep transient detours separate because they preserve the home binding.

Eight-phase plan: hold a live binding for cache, release it only on real evidence, bound retry amplification and fan-out spend, group credentials by observed quota and cache domain, reinforce the Codex prompt cache, and report cache state honestly.
Pooled routing moved a live conversation whenever its account crossed autoSwitchThreshold, and moved it to whichever account was strictly cooler with no floor under the destination. Provider prompt caches are account-isolated, so every hop re-sent the whole prefix; once a pool sat in the 80-99% band the coolest account was still over the threshold and the thread was handed on again every turn. The same predicate short-circuits the 60s re-score interval, so in that band the thread was re-scored per request. pool.cacheAffinity shipped as the opt-in cure (#4292) but defaulted off, so the install that gets hurt was exactly the install that had never heard of it. Three changes: - pool.cacheAffinity now defaults ON. A bound thread keeps its account until that account genuinely cannot serve. An explicit false restores capacity-first routing. - A bound thread may only move to a destination with genuine quota headroom and strictly lower usage, under either setting. CODEX_UNKNOWN_USAGE_SCORE is 101, so an unmeasured account is excluded without a special case. When the whole pool is hot, nobody moves. - A transient failure streak no longer deletes a live binding. The request detours to a remembered alternate while the thread keeps its home, and returns as soon as that account serves again; a hold outliving 10 minutes releases normally. This is independent of cacheAffinity, because attributing a 5xx is not a quota preference. The model-detour lane gets the same hold. Quota refusals (429/402), pauses, plan exclusion, credential invalidation, generation bumps and TTL expiry still release a binding, unchanged. The account-wide clear on a transient streak is gone: each pinned thread reaches the same detour on its own next request, and wiping the map retired bindings for quota scopes the failure never described. Preview never starts a hold or picks a fresh detour, because pickRoundRobinAccount commits and advances the ring and preview is contractually read-only; it reports the detour the request path already chose. Six existing tests encoded the old default and now state it explicitly with pool.cacheAffinity: false.
…4546) Every locale of the provider reference, the accounts CLI page and the dashboard guide documented pool.cacheAffinity as opt-in and off, and described the auto-switch threshold as the bar for moving a bound task. Both became wrong when the default flipped, and a default documented in eight languages is wrong in eight languages. Also corrects the transient-failure wording: a 5xx streak no longer releases a live binding, independently of cacheAffinity. structure/providers/openai-tiers.md and the GUI strategy hints carried the same two claims. The auth-context regression now asserts the session comes home to its held account once health clears, which is what proves a late failure did not disturb the binding; under the old rule there was a newer binding to protect instead.
) Four dashboard tests pinned the sentences that said the usage threshold rebinds a bound task. Those strings changed with the default, so the assertions moved to the claims the copy now makes: bound tasks keep affinity by default, and the threshold rebind is what an explicit pool.cacheAffinity: false restores.
The L2 lane unit shipped its headroom floor while this unit was in flight. Both quota call sites use pickCacheSafeQuotaReplacement unchanged; this unit covers what that PR left open.

Separate failure recovery from cache-safe affinity rebinding.
The preceding text in all three translations says that 401/403 reauthentication or 429 cooldown can clear affinity and rotate to another eligible Pool account. However, the following bullet uses “only” in a way that can apply the lower-usage and quota-headroom requirements to those failure releases.
This contradicts src/codex/routing.ts: pickAlternateCodexAccount uses pickLowestUsageCodexAccount for quota recovery, and getEligiblePoolAccounts does not require hasCodexQuotaHeadroom. A 429 fallback can therefore remain above autoSwitchThreshold. Scope the lower-usage and headroom requirements to exhaustion-based and threshold-driven cache-affinity rebinding. Keep 401/403 and 429 recovery as separate eligible-account releases. Apply the clarification to the English source at docs-site/src/content/docs/guides/web-dashboard.md#L251-L255 and mirror it in the Turkish, Simplified Chinese, and Traditional Chinese bullets.

Correct the cache-affinity comments.
With default affinity, mayRebindAffinityForQuota does not rebind on autoSwitchThreshold alone. It requires an unusable account or usage of at least 100. With pool.cacheAffinity: false, threshold rebinding returns.
The replacement helper still requires quota headroom and strictly lower usage. Therefore, false does not restore routing “byte-for-byte.”
Update both comments to distinguish these policies.

comments near mayRebindAffinityForQuota to accurately describe both policies:
default affinity only rebinds for an unusable account or usage of at least 100,
while pool.cacheAffinity: false restores threshold-based rebinding but still
requires quota headroom and strictly lower replacement usage. Remove the claim
that false restores routing byte-for-byte.

…d agree with preview (#4546) (#4589) Follow-up to #4580, from review of the merged commit. P1: preview and resolve disagreed on the FIRST detour. Preview refused to pick one because pickRoundRobinAccount commits and advances the ring, so it returned null and fell through to the ordinary binding while resolve served from a fresh alternate. Subagent fallback scores the previewed account to decide whether a model is reachable, so it could retire a model over usage the request would never touch. Preview now peeks the same candidate through peekAlternateCodexAccount, which delegates for every strategy except round-robin because that is the only branch with a side effect. P1: when no detour existed the code fell through and deleted the binding. A provider-wide 503 soft-avoids every sibling, which is precisely when the candidate list is empty, so the hold did not cover the failure it was written for. Being unable to send is not the same as forgetting which account owns the conversation: the binding now survives and the bound account is returned, on both the ordinary and model-detour lanes. reset-first could still move a bound thread onto an account with no usage reading, because hasCodexQuotaHeadroom answers true for unknown. The quota strategy excludes those through its strictly-cooler compare; reset ordering has no such compare and now says it explicitly.

Summary
Pooled Codex routing moved a live conversation whenever its account crossed
autoSwitchThreshold, and moved it to whichever account was strictly cooler with no floor under the destination. Provider prompt caches are account-isolated, so every hop re-sent the entire prefix. Once a pool sat in the 80-99% band the coolest account was still over the threshold, so the thread was handed on again the next turn, and the turn after that. The same predicate short-circuits the 60-second re-score interval, so in that band a bound thread was re-scored on every request. #4546 reports the result: roughly 1.9B total tokens and 323M uncached tokens across 15,607 requests in about thirteen hours, with a 7k-token turn arriving upstream as a 150k-token turn.pool.cacheAffinity(#4292) already raised the eviction bar, but it was opt-in and off, so the install that gets hurt is exactly the install that never heard of it. And turning it on did not close the hole: a transient failure streak deleted the binding through a different path that never consulted the flag.Three changes, each independently revertible:
pool.cacheAffinitydefaults ON. A bound thread keeps its account until that account genuinely cannot serve: unusable, paused, plan-excluded, credential-invalid, generation-stale, TTL-expired, quota-refused, or known at 100%. An explicitfalserestores capacity-first routing byte-for-byte.CODEX_UNKNOWN_USAGE_SCOREis 101, so an unmeasured account can never be strictly cooler than a known over-threshold score and is excluded without a special case. When the whole pool is hot, nobody moves - there is nothing to win by trading a warm prefix for an equally hot account.cacheAffinity: attributing a 5xx is not a quota preference, and fix(responses): keep the retryable main-refresh refusal an overload, not a bad key #4269 already showed how badly failure classification misfires when it reads the wrong signal. The model-detour lane gets the same hold, otherwise a model-scoped request drops its pin on three 503s and falls back to a home account that may not be entitled to the model.Release paths are deliberately untouched. Quota refusals (429/402), pauses, plan exclusion, credential invalidation, generation bumps and TTL expiry still release a binding. This narrows a preference; it never weakens a refusal.
Two details worth a reviewer's attention:
pickRoundRobinAccountcommits and advances the ring, andpreviewCodexAccountForRequestis contractually side-effect-free; it reports the detour the request path already chose. Preview and resolve still agree, which matters because preview is what subagent fallback scores.Six existing tests encoded the old default and now state it explicitly with
pool.cacheAffinity: false, keeping their original intent.late transient failure cannot disturb a held Desktop affinity bindingchanged meaning rather than expectation: under the hold there is no newer binding to protect, so the proof that the late failure did no damage is that the session comes home to its held account once health clears.Documentation moves with the behaviour across all eight locales of the provider reference, the accounts CLI page and the dashboard guide, plus
structure/providers/openai-tiers.mdand the dashboard strategy-hint strings undergui/src/i18n/. Those strings are copy-only -autoSwitchQuotaDescandstrategyHintQuotanow say the threshold governs unbound work while a bound task keeps its account by default. No control, layout or component changed, and no toggle was added.Rebased onto current
dev, which now carries #4581. That PR shipped the destination rule for the same issue aspickCacheSafeQuotaReplacement, and this branch uses it unchanged at both quota call sites rather than adding a parallel path. #4581 deliberately left three things open, recorded in its own review, and they are this PR's scope: a below-threshold sibling still took the thread once, cache affinity was still opt-in, and the transient path was untouched.Planning and the follow-on phases (retry-amplification budgets, worker fan-out isolation, quota/cache domain grouping, Codex prompt-cache reinforcement) are recorded in
devlog/_plan/260914_cost_guard_stabilization/. Builds on the headroom-floor analysis fromdevlog/_plan/260914_l2_pool_routing_cache/010_cache_safe_rebind.md, which landed as #4581.Closes #4546
Verification
src/codex/routing.ts, which returnedfailon the first design and is the reason three defects are absent from it: a detour that re-picked per request (cold prefix on a rotating series of accounts), a preview that would have advanced the round-robin ring, and a model-detour lane that still dropped its pin.Checklist
