Make every effective-active read scope-aware.

The plan keys manualPreference by codexPoolKeyForScope but also requires getEffectiveActiveCodexAccountId to return the live preference. The current API at src/codex/routing.ts:1625 accepts no quotaScope. Scoped paths at :1379, :2029, and :2218 can therefore read the shared codex preference for spark or reserve; the resolved request can then consume that shared one-shot. Pass quotaScope through these reads, or bypass the preference for independent scopes. Add a regression test proving that an independent scope neither applies nor consumes the shared preference.

consumed.

Seeding is explicit only. The entry is written by
`resetCodexRoutingForManualSelection` and nowhere else. There is no lazy seed
from `config.activeCodexAccountId` on first read, because an absent entry plus a
lazy seed would let an independent quota scope invent a preference it was never
given.

Invalidation, since Codex has no account-side equivalent of Anthropic's
`selectionRevision` (`apiKeySelectionRevision` is for keys and the store
`generation` is credential lineage): the preference is dropped only by an
OPERATOR-driven change of the active account, meaning another
`resetCodexRoutingForManualSelection` naming a different account, or an explicit
clear. A POOL-driven move must not drop it.

That distinction is load-bearing and was missed twice. An earlier draft said
"drop it whenever the accountId no longer equals the persisted active account",
which contradicts the guarantee below: `promoteActiveCodexAccount` (`:1677`)
calls `releaseCodexAccountPinFor` and then `setActiveCodexAccount` (`:1660`,
which clears `runtimeActiveCodexAccountId` at `:1661`) BEFORE it would reach the
guarded `remember`. Under the old rule a failover promote would move the
persisted active, look like a mismatch, and silently spend the operator's
one-shot. Keying invalidation to the operator path instead of to value equality
is what keeps F1 and F4 from cancelling each other.
2. `resetCodexRoutingForManualSelection` (`:870`) additionally seeds
`manualPreference` from `config.activeCodexAccountId`, mirroring
`anthropic-routing.ts:810`. It keeps clearing thread affinity, clearing the
runtime cursor and seeding round-robin, and keeps preserving cooldown.
3. `pickUnboundStrategyAccount` (`:1466-1481`) returns early while a preference is
live, so round-robin and fill-first cannot call `rememberActiveCodexAccount`
over the operator choice.
3. The guard sits on BOTH writers, not only on `remember`.
`rememberActiveCodexAccount` (`:1644`) becomes a no-op while a live preference
names a different account, which closes its four call sites `:1470`, `:1481`,
`:1678` and `:2286` at once. That alone is still insufficient, because
`promoteActiveCodexAccount` (`:1677`) releases the pin and calls
`setActiveCodexAccount` (`:1660`) before it ever reaches `remember`. So
`promoteActiveCodexAccount` and `setActiveCodexAccount` also check for a live
preference and leave the operator's account in place for the pool-driven paths
(failover `:1878`, model detour `:2213`, exclusion `:1704`, cooldown `:2534`
and `:2584`). An operator PUT still moves them, because that path seeds a new
preference first.
4. `getEffectiveActiveCodexAccountId` (`:1625`) returns the preference account
while one is live, ahead of the runtime cursor.
5. `resolveCodexAccountForThreadDetailed` (`:2069`) checks the preference before
`pickUnboundStrategyAccount` (`:2194`). If it names the persisted active
account and that account is selectable and not exhausted, return it with a
`manual` reason and do not call `rememberActiveCodexAccount`.
`pickUnboundStrategyAccount` (`:2194`). If the preference account is selectable
and not exhausted, return it with a `manual` reason and do not call
`rememberActiveCodexAccount`. Honouring does NOT require the preference to still
equal `config.activeCodexAccountId`: a pool-driven promote may legitimately have
moved that value, and treating the difference as staleness is the mistake the
audit rejected twice.
6. `previewCodexAccountForRequest` (`:1987`) peeks the preference without
consuming it.
7. NEW consume-on-success, mirroring `anthropic-routing.ts:799-800`: after a
successful token and admission, set `manualPreference = null` and confirm
`config.activeCodexAccountId`. A failed lookup must not spend the preference.
7. NEW consume-on-success, mirroring `anthropic-routing.ts:799-800`. Codex has no
equivalent of the Anthropic admission commit, so the hook must be named
explicitly: consume at the same point that already records a successful upstream
outcome for the resolved account, `recordCodexUpstreamOutcome`, and only for a
non-quota success. Consuming must call `setActiveCodexAccount` rather than only
nulling the entry, because nulling alone leaves `runtimeActiveCodexAccountId`
pointing at the pool's earlier pick and the next dispatch would silently return
to it. A failed lookup must not spend the preference.

Added after the A-phase audit, because the three files above prove the ceiling and
the drain but not these:

- a live preference survives `promoteActiveCodexAccount` reached through failover
and through a model detour, and survives a priority preemption
- an independent quota scope neither applies nor consumes the shared preference
- an operator selecting a different account replaces the previous preference, while
a pool-driven promote that moves the persisted active account does not spend it
- criterion c-2 directly: with a pinned account that is selectable and under
`autoSwitchThreshold`, auto-switch holds, under both the quota strategy and
round-robin or fill-first

## Out of scope

## Audit record

The A-phase reviewer returned FAIL with one blocker and four majors, all folded
above: the overwrite hole at `promoteActiveCodexAccount` and preemption, the
singleton-versus-scope-keyed state, the missing invalidation rule in the absence
of an account-side revision, the pin-versus-preference disagreement after a
released pin, and the test gap against criterion c-2.

The generic OAuth kind gets no preference in this layer; that arrives with the
kernel in phase 2. No management or GUI change.

## Staleness re-verification

Re-verified at the wp1 P entry against `origin/dev` `16f18d654`, after lane L3
landed `de1d88739`, `abec9ee51` and `7f91737c2` on the owned files. Every anchor
this document depends on is unchanged from the `dd9a2906b` reading:

| Symbol | Line on 16f18d654 |
|---|---|
| `getEffectiveActiveCodexAccountId` | 1625 |
| `rememberActiveCodexAccount` | 1644 |
| `applyQuotaAutoSwitch` | 1784 |
| `resetCodexRoutingForManualSelection` | 870 |
| `pickUnboundStrategyAccount` | 1446 |
| `releaseDrainedCodexAccountPin` | 1757 |

The design therefore survives the lane's landings. What does not change is the
coordination risk: L3 still owns these files for the dispatch round, so the B
phase of this work-phase must not open until that ownership clears. Re-run this
table at that point, because the guarantee above is a snapshot of `16f18d654`.

## Availability and the slice this cycle can actually take

Re-verified at the wp2 P entry against `origin/dev`. The lane partition for the
round in flight does not list `src/oauth/generic-account-failover.ts`,
`src/oauth/pool-settings-capability.ts` or `src/codex/pool-rotation.ts`, so the
kernel extraction and the generic-kind strategy work are available now. Two things
are not:

- `src/codex/routing.ts` is owned by lane L3, so the Codex-side import swap waits.
- `src/server/responses/core.ts` is owned by lane L1 and is the most contended
file in the round with four open PRs, which is also why the wp4b call-site
wiring could not follow #4277 immediately.

This cycle takes the kernel, the Anthropic import swap and the generic consumer.
Only the CODEX import swap is deferred, and it is deferred for free: once
`pool-rotation.ts` re-exports the kernel, `src/codex/` keeps its existing import
path and needs no edit at all. So the contended files stay out of this PR without
the kernel being an orphan.

Two kinds of change are moving here and they carry different risk, which is why
only one of them is behind the flag:

- **Relocation** is behaviour-preserving. Moving the state and primitives into
`pool-kernel.ts` and re-exporting them changes no selection outcome, so it is
not flagged. `git` history and a green existing suite are its proof.
- **Behaviour** is flagged. The generic kind consuming `strategy` and
`autoSwitchThreshold`, and the DTO reporting `inert: false`, only happen when
`pool.kernel` is on. Flag off restores today's outcomes exactly, because the
pre-kernel path is the same code reached through the shim.

Describe flag-off as behavioral parity, not restoration of the pre-kernel implementation path.

Relocation into src/oauth/pool-kernel.ts is unconditional, and src/codex/pool-rotation.ts becomes a re-export (020_phase2_shared_kernel.md:34-40,111-112). However, the mandatory reversibility section defines flag-off as rollback and says Codex and Anthropic take the “pre-kernel code path” (020_phase2_shared_kernel.md:152-164). Disabling pool.kernel cannot restore the relocated implementation. It can only require the kernel-backed path to preserve the old selections. Rewrite this rollback criterion to require behavior parity after the golden-trace proof, without claiming implementation-path restoration.

shape was rejected by the audit: both existing copies walk a STABLE FULL roster

whenever an ineligible id sits between two eligible ones.
- extend the reconcile sweep to `generic:*`. `buildGenerationContext` already fills
`oauthAccountKeys` from `listLiveOAuthAccountKeys` as `provider\0id` for every
live OAuth provider, so the sweep needs no new field and no Codex dependency;
today those keys are simply skipped as `valid === null`.

Preserve the 429 ring and rotation state for each strategy.

At src/oauth/generic-account-failover.ts:202-217, the 429 path filters failedAccountId and cooldowns, then builds a ring that starts after the failed account. The plan only says to call pickRoundRobinAccount(genericPoolKey(name), ...). That helper consumes the supplied list order and mutates weighted state (src/codex/pool-rotation.ts:159-195); it does not reconstruct the failed-account ring. Pass the filtered ring to the helper, clear failed-account sticky state, and define when notePoolRotationSuccess records a successful retry. Apply equivalent exclusion and stable-roster handling to fill-first. Add repeated-429 and ring-wraparound tests; the current tests cover only the pre-change quota path.

`seedPoolRotationAccount(genericPoolKey(provider), accountId)` beside it, mirroring
what `resetAnthropicRoutingForManualSelection` already does for Anthropic.
`clearGenericFailoverHealth` is the wrong map and `clearPoolRotationState` wipes
where seeding is wanted.

Add a focused regression test for generic manual-selection seeding.

The Phase 2 test list covers generic strategy selection and capability assertions. tests/oauth/generic-oauth-failover.test.ts:75-92 only sets the active account directly and checks preferredInitialAccount; it does not exercise the management route or the next generic dispatch. Add a test that performs manual selection through the management route and verifies that the next generic dispatch uses the selected account.

MODIFY `src/oauth/pool-settings-capability.ts` — report `inert` from the flag rather
than as a type literal. While `pool.kernel` is off the generic DTO must keep saying
`inert: true`, because nothing consumes the strategy yet and the reversibility rule
below requires the old behaviour to be exactly restorable. The literal becomes a
computed field and only turns false once the kernel is on.

Known readers of that field, all of which move in the same PR:
`src/cli/account-extended.ts` (forces generic auto-switch inactive),
`tests/server/account-pool-management-api.test.ts` and
`tests/cli/cli-account-pool-verbs.test.ts`. The GUI does not read it.
Also lift the `stickyLimit` rejection at `oauth-account-routes.ts:395` and update
`src/types/provider.ts:512-518` comments.

MODIFY `src/oauth/anthropic-routing.ts` — import from the kernel. `src/codex/`
keeps importing `./pool-rotation`, which is now a re-export, so this layer needs
no edit inside lane L3's files at all. The audit confirmed the shim is sufficient:
`routing.ts`, `auth-api.ts`, `account-priority.ts` and
`state-store-registrations.ts` all keep their existing import path.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add the missing kernel bindings to the generic and management consumers.

The change surface calls pickRoundRobinAccount(genericPoolKey(name), ...) and seedPoolRotationAccount(genericPoolKey(provider), accountId), but src/oauth/generic-account-failover.ts imports nothing from the pool modules, and src/server/management/oauth-account-routes.ts imports only normalization and parsing helpers. The src/codex/pool-rotation.ts re-export preserves the existing path but does not add names to either module's local scope. Add genericPoolKey, pickRoundRobinAccount, and pickFillFirst to the generic failover import, and add genericPoolKey and seedPoolRotationAccount to the management route's existing import.

would have forced an edit inside lane L3's freeze. The second was that dropping
`inert: true` unconditionally contradicts this document's own reversibility rule,
