Summary

Makes a generic OAuth provider's stored pool strategy actually select an account, behind a new opt-in pool.kernel flag. Until now strategy and autoSwitchThreshold were persisted, reported through the management contract, settable from the CLI — and read by nothing. The DTO said so with inert: true.

Two paths had to branch, not one. Branching only the pre-dispatch preference would leave the setting inert in practice the moment anything actually failed, which is the case an operator picks a strategy for.

Strategy initial preference 429 rotation
flag off, or absent / quota unchanged unchanged
round-robin peek the shared ring advance the ring
fill-first hold the active account under its threshold take the next eligible account, never the cooled one

Three things are worth calling out, because each was forced by the code rather than chosen:

  • Both quota guards are skipped for the two new strategies. hasHeadroomEvidence refuses every provider with no quota data at all — which is exactly where round-robin is the point — and the healthy-active early return fires before autoSwitchThreshold can ever be read, so fill-first could never reach its own test. They still guard the quota answer, which is unchanged.
  • The round-robin commit is at admission, not at proposal. peekRoundRobinAccount never creates the pool state and notePoolRotationSuccess returns immediately without it, so a peek-only path leaves the ring with nothing to advance and round-robin proposes the same account forever. noteGenericPoolSelection takes the live pick at commit, the same shape commitAnthropicSelectionRouting already uses. Its early return is the safety story for the core path: it is reached on every generic first dispatch, so anything but round-robin leaves the cursor untouched.
  • Fill-first walks the sorted full roster. The account store holds accounts in login order, so two operators who added the same accounts in a different sequence would otherwise rotate differently, and walking the eligible subset changes the wrap order whenever an ineligible id sits between two eligible ones — the bug the shared kernel already carries a stableAll argument to avoid.

Also fixed here, the generic half of the defect #4284 closed for Codex: a manual account selection cleared the presence count but never seeded the rotation cursor, so an operator's pick lost the very next dispatch to sticky rotation.

stickyLimit joins the generic contract (the CLI verb already routed it; only the server refused it). quotaWindow is still refused.

Design and audit trail: devlog/_plan/260911_account_pool_unification/020_phase2_shared_kernel.md. The plan audit returned FAIL on three blockers — two of which corrected claims the plan made itself — and passed on re-audit.

Verification

  • bun x tsc --noEmit — pass
  • bun test tests/oauth/generic-oauth-failover.test.ts tests/server/account-pool-management-api.test.ts tests/cli/cli-account-pool-verbs.test.ts — 93 pass, 0 fail
  • Red control: with the strategy branch disabled, 5 of the 7 new strategy cases fail. The 2 that stay green are the invariance cases — flag off, and quota unchanged — which are supposed to pass either way.
  • bun run privacy:scan — passed

Two existing tests were corrected rather than allowed to keep passing. The DTO marker test located its slice with indexOf("inert: true;"); once the field became inert: boolean, that returned -1 and slice(start, -1) handed back nearly the whole file, so all three assertions still passed while the test checked nothing. It now fails closed on a missing anchor. And the CLI test fed inert: false through a malformed-capability loop, which would have rendered the live feature as an unknown capability.

Docs move with it: the English reference plus seven translated locales all stated that a generic strategy and threshold never steer selection, which is now true only with the flag off.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

  • New Features

    • Added configurable generic OAuth account-pool strategies: round-robin and fill-first.
    • Added optional pool-kernel activation to apply saved selection settings.
    • Added sticky account limits and threshold-based selection for supported strategies.
    • Improved account rotation and selection consistency across switching and failover scenarios.
    • Added clearer capability reporting for applied, inactive, and unsupported settings.
  • Documentation

    • Updated CLI and configuration documentation across supported languages with new pool behavior, defaults, and status meanings.

…rnel

round-robin and fill-first now actually select an account for a generic OAuth provider, on both the initial-preference and the 429 path. Both quota guards are skipped for them deliberately: hasHeadroomEvidence refuses every provider with no quota data, which is exactly where round-robin is the point, and the healthy-active early return fires before autoSwitchThreshold can be read. quota, and the flag off, keep the pre-kernel path unchanged.

The live round-robin pick commits at admission rather than at proposal, matching commitAnthropicSelectionRouting: peek never creates the pool state and notePoolRotationSuccess no-ops without it, so a peek-only path would never turn the ring.
The inert contract was published in the English reference and in seven translated locales, all of which said a generic strategy and threshold never steer selection. That is now true only with pool.kernel off, so each page describes both states rather than the old one.

Generic OAuth pool behavior and its management documentation still contain several localized inconsistencies that can cause confusing account selection, status reporting, or configuration behavior. The impact is bounded, but these follow-ups should remain visible before merge.

설명
지금 dev(HEAD 29d632ff2, #4284 수동 선택이 풀 커서를 이기는 단계까지 올라온 상태)에서 일반 OAuth 풀은 strategyautoSwitchThreshold를 설정·저장·관리 API로 보여 주기는 하는데, 실제로 계정을 고르는 코드는 읽지 않습니다. src/oauth/pool-settings-capability.ts의 DTO가 inert: true로 그 사실을 그대로 적어 두고, preferredInitialAccount / rotateGenericOAuthAccountOn429는 할당량(quota) 경로만 탑니다. 그 바로 아래에 이미 #4279로 src/oauth/pool-kernel.ts가 들어 있어서 Anthropic·Codex가 쓰던 round-robin / fill-first 원시 연산은 공유 커널에 있습니다. 그런데 일반 OAuth 쪽은 아직 그 커널을 “전략 소비”로 연결하지 않은 상태입니다.

이 PR(#4289, 브랜치 codex/generic-pool-kernel)은 계정 풀 통일 계획의 phase 2입니다. 계획 문서는 devlog/_plan/260911_account_pool_unification/020_phase2_shared_kernel.md에 있습니다. 핵심은 새 옵트인 플래그 pool.kernel(기본 꺼짐, src/config.ts / src/types/config.ts)입니다. 플래그가 꺼져 있으면 예전과 똑같이 동작하고, 켜져 있고 strategyround-robin 또는 fill-first일 때만 일반 풀이 전략을 읽습니다. quota이거나 전략이 없으면 예전 경로 그대로입니다. 이렇게 하면 “저장만 되고 안 쓰이던” #695 계약을 실제로 쓰게 하면서도, 기본값을 바꾸지 않아서 기존 운영자를 깨지 않습니다.

선택 경로는 두 군데를 같이 갈라야 의미가 있습니다. (1) 보내기 전 선호 preferredInitialAccount — round-robin은 peekRoundRobinAccount로만 제안하고, 커밋은 나중에 합니다. fill-first는 활성 계정이 임계값 아래면 유지하고, 넘으면 정렬된 전체 명단(stableGenericRoster)에서 다음 가능 계정을 고릅니다. (2) 429 회전 rotateGenericOAuthAccountOn429 — 여기서도 같은 전략으로 갈라서, 실패가 났을 때 다시 quota 랭킹으로 돌아가 전략이 무력화되지 않게 합니다. round-robin의 커밋은 noteGenericPoolSelectionsrc/server/responses/core.ts에서 계정이 실제로 승인된 뒤에만 호출합니다. peek만 하면 풀 상태가 안 생겨서 링이 영원히 같은 계정을 고르는 문제를 Anthropic의 commitAnthropicSelectionRouting과 같은 모양으로 막습니다.

부가로, #4284가 Codex에서 고친 “수동 선택이 다음 디스패치에서 sticky 회전에 지는” 결함의 일반 풀 반쪽도 같이 닫습니다. src/server/management/oauth-account-routes.ts에서 활성 계정을 바꿀 때 seedPoolRotationAccount(genericPoolKey(...))로 커서를 심습니다. 계약 쪽에서는 stickyLimit을 일반 풀이 받을 수 있게 열고(quotaWindow만 거절), DTO의 inert를 리터럴 true가 아니라 pool.kernel에 따라 계산되는 boolean으로 바꿉니다. CLI·다국어 docs도 “항상 inert”에서 “플래그 상태에 따라”로 맞춰 두었고, 테스트는 새 전략 케이스 + inert DTO 앵커 수정 + CLI live/off 구분을 넣었습니다. 작성자 검증: tsc, 관련 테스트 93 pass, privacy:scan, 전략 분기 끄면 신규 케이스 5/7이 깨지는 red control까지 적혀 있습니다. 현재 dev 방향(풀 커널 + 수동 선택)과 정면으로 이어지는 phase-2라서 우선순위는 높게 잡았습니다.

라인 수준
src/server/management/oauth-account-routes.ts (setActiveAccount 직후 seed) - genericPoolKey(provider)로 항상 시드합니다. Anthropic도 이 경로를 타면 generic:anthropic 키가 생기고, 실제 Anthropic 회전은 POOL_KEY_ANTHROPIC("anthropic")만 봅니다. 해롭진 않지만 orphan 상태입니다. poolSettingsCapability(...) === "generic"일 때만 시드하는 편이 맞습니다.
src/server/responses/core.ts (noteGenericPoolSelection 호출) - 변경은 작지만 이 파일은 지금도 여러 열린 PR(#4287, #4259, #4242 등)이 만지는 충돌 지점입니다. 머지 순서만 조심하면 됩니다.
src/oauth/generic-account-failover.ts (noteGenericPoolSelection 뒤 빈 줄 두 줄) - 동작과 무관한 형식 잡음입니다.
preferredInitialAccount의 전략 분기 - isProactivePreferenceEnabled 가드 안에 있어서, kernel+round-robin이어도 oauthAccountFailover.enabled가 꺼져 있으면 초기 선호는 안 돕니다. 429 경로는 presence 쿼럼으로 따로 돕니다. 의도된 분리로 보이지만, 운영자가 “strategy만 켰는데 왜 안 도느냐”고 물을 수 있으니 docs에 한 줄 더 있으면 좋습니다.

메인테이너의 판단이 필요한 지점

  • pool.kernel 기본값을 계속 off로 둘지, 곧 기본 on으로 올릴 로드맵을 언제 열지.
  • core.ts 충돌 레인에서 이 PR을 다른 responses 작업보다 먼저 넣을지.
  • Anthropic set-active 경로의 orphan generic:anthropic 시드를 이번 PR에서 가드할지, 후속으로 둘지.
  • stickyLimit을 일반 계약에 넣은 뒤 GUI/대시보드가 inert: boolean + stickyLimit을 이미 소화하는지, 아니면 CLI/API만 먼저 살아도 되는지.

너의 추천
CI(changes 등) 초록 확인 후 머지해도 됩니다. 머지 전에 set-active 시드를 generic kind에만 거는 한 줄 가드를 넣고, core.ts는 충돌만 재확인하면 phase-2 열차에 바로 실을 만합니다. orphan 시드 가드를 후속으로 빼도 동작 회귀는 없습니다.

P2 Badge Treat a zero threshold as disabled

When pool.kernel and fill-first are enabled, ocx account auto-switch <provider> off stores 0, but this comparison treats every measured account as over the threshold because its usage is always at least zero. The next request therefore switches accounts instead of disabling threshold-based switching; return false for a zero threshold before applying the comparison.

P2 Badge Base threshold status on the active strategy

With pool.kernel: true, this reports inert: false solely from the global flag, even when the provider uses quota/round-robin or has proactive preference disabled. If a threshold remains stored in either case, cmdAutoSwitch consequently reports enabled: true and says the threshold is applied although preferredInitialAccount never consumes it. The DTO or CLI status needs to account for the effective fill-first strategy and proactive enablement.

P2 Badge Preserve unknown pool settings during config saves

Because a plain Zod object strips unknown properties, loading a configuration written by a newer binary, such as pool: { kernel: true, futureOption: ... }, removes futureOption from the returned config. CLI paths that subsequently call the unguarded saveConfig() then overwrite the file with that property missing. Make this new namespace passthrough-compatible, as other extensible configuration objects are, so routine saves do not destroy forward-version settings.

Update every document mapped to the changed source areas in structure/INDEX.md, as required by the repository ownership policy.

Include stickyLimit in the generic OAuth contract summary.

At docs-site/src/content/docs/reference/configuration/providers.md:590-593, the summary lists only strategy and autoSwitchThreshold. The generic provider type accepts stickyLimit (src/types/provider.ts:533-538), and the CLI maps ocx account sticky to that field (src/cli/account-extended.ts:888-890). Add stickyLimit to the summary and state that it applies only to round-robin.

Treat threshold 0 as disabled.

ocx account auto-switch <provider> off persists autoSwitchThreshold: 0. A live generic pool returns that value with inert: false, but this condition reports enabled: true and renders auto-switch: on.

Guard generic rotation seeding behind the pool kernel

seedPoolRotationAccount creates and mutates generic:${provider} state without checking config.pool?.kernel. The active-account route accepts providers outside the generic failover contract, including Anthropic. Call this helper only when the kernel is enabled and isGenericFailoverProvider(provider, config.providers[provider]) returns true; keep the separate Anthropic reset path unchanged.

Validate oauthAccountFailover.stickyLimit in direct configuration input.

providerConfigSchema in src/config.ts:580 passes unknown provider fields through, so validateConfigCandidate accepts stickyLimit: 0. genericStickyLimit() then sends it to normalizeAccountPoolStickyLimit(), which silently changes it to 1. This violates the documented 1–100 contract and differs from PUT /api/oauth/accounts/pool, which rejects the value at src/server/management/oauth-account-routes.ts:426-430. Add nested schema validation or a superRefine check for oauthAccountFailover.stickyLimit, and test invalid values through validateConfigCandidate.

Clear the pool-kernel state in this test fixture.

selectionState in src/oauth/pool-kernel.ts:22 is module-global, and clearGenericFailoverHealth() does not clear it. The first test mutates generic:xai through noteGenericPoolSelection() at tests/oauth/generic-oauth-failover.test.ts:553-558. The 429 test then reads that state through pickRoundRobinAccount() at lines 633-637. The current sequence still selects ids[1]!, but the fixture is not isolated. Clear clearPoolRotationState() in beforeEach and afterEach, as the other pool tests do.

- The APPLIED value is echoed, not the requested one, so a server-side normalization stays visible.
- Values are not re-validated in the CLI: the server owns the strategy names and the 1-100 sticky bound.
- `anthropic` owns the full pool contract. Other OAuth providers reach the same endpoint with a generic subset (enabled/strategy/autoSwitchThreshold) whose settings persist but do not yet steer selection; `sticky` and `quotaWindow` are refused for them.

Use stickyLimit in the generic contract description.

Line 542 names the field sticky, but the generic pool API uses stickyLimit. src/cli/account-extended.ts sends and reports stickyLimit, and tests/cli/cli-account-pool-verbs.test.ts asserts that field. A user following this reference may send sticky, which can make the setting appear unsupported or be ignored. Change the list to enabled/strategy/autoSwitchThreshold/stickyLimit, or document an explicit alias if the server accepts one.
