Conversation
In Pool mode, the synthetic main-liveness answer for a request carrying main's own forwardable bearer was the manual-pin predicate. For an unpinned request that predicate is false, so codexAccountUnusableReason reported main_credential_unavailable, getEligiblePoolAccounts never listed main, and the strategy compared only the stored accounts. Main then served only as the fallback after every stored account had failed, so a pool with one stored sibling degraded to "stored account until it cannot serve, then main" whatever the usage numbers, the strategy or codexAccountPriorities said. requestOwnedMainCredentialIsLive now answers that question from the credential the request actually carries, and final authentication plus both previews share the one expression. A selected main is served from the caller's bearer before any physical claim or materialization, so the read fence is unchanged: no stored entitlement discovery, denial-cache validation, reconciliation, priming, affinity or health state. Account-gated models stay excluded, and retained recovery or a draining profile still make main ineligible. Closes #5019

When the request-owned bearer wins pool ordering here, it is returned as { kind: "main", accountId: null }. The downstream alternate-account path in src/server/responses/passthrough-dispatch.ts is gated by usesCodexForwardPoolAuth, which accepts only pool and main-pool, so a pre-stream 429/402 or transient 5xx from this bearer is returned directly even when a stored sibling is available. Before this change, the caller bearer was used only after stored candidates were exhausted; preserve enough selection origin to retry with __main__ excluded, without attributing durable health state to the request-owned credential.

…dacy Making main an ordinary candidate moved the cooled account out of the selection, and with it the refusal that protected the cooldown: a caller whose own credential IS a cooled Pool subscription was served as main, resurrecting the cooldown it was inside. callerIsCooledPoolAccount only ever asked this of the selected account, which was sufficient while main could not be selected. Eligibility now asks it of every cooled sibling, so the caller that owns one keeps the cooled account as its selection and the existing cooldown machinery produces the same refusal it did before. An unreadable caller identity still fails closed. Preview passes the term explicitly as false: cooldown identity is not modelled there and never was, because it decides a refusal rather than which account serves.

Three of your own regressions are red at this head, all fast assertions rather than timeouts, so this is the fix not reaching the path the tests drive rather than inherited noise:
293 other cases in that shard pass, and The second and third are the interesting pair: one says the fallback must not resurrect a cooled subscription and the other says it must follow the stable user id rather than the recorded email. If a single change can satisfy the first case but not those two, the selection is probably keying on the wrong identity, which is the same class of defect #4593 fixed for stored Direct account identity. Worth checking whether the bearer you admit and the account you record are resolved through the same key. Do not relax any of the three to match current behaviour.

Updated read at this head, and one of these is more serious than the others. An existing invariant is broken. Please treat that as the primary finding rather than as collateral. The question it forces is whether "a caller's main bearer may be selected for a pool request" can be true at all without direct and pool credentials becoming reachable from each other. If it can, the mechanism needs to be explicit about what keeps them independent; if it cannot, the feature needs a different shape. This sits on the credential boundary that Your own three regressions are still red, now on Windows as well as Linux: The pairing is suggestive: the two that fail are the ones constraining which identity the fallback follows and what it must not resurrect. If a single change satisfies the first case but not those two, the selection is probably keying on the wrong identity — the same class #4593 fixed for stored Direct account identity. Worth checking whether the bearer you admit and the account you record resolve through the same key. Do not relax any of the four. If the independence assertion is the one that is wrong, that is a much larger claim and needs to be argued explicitly. |

I verified the selection change at exact head 686b18063d. The report is real and this direction is close, but the new caller-main winner loses pool recovery.
When the request-owned main bearer wins ordering, resolveCodexAuthContext returns kind: "main" with no account id. Downstream alternate-account recovery is gated by usesCodexForwardPoolAuth, which accepts only pool and main-pool. A pre-stream 429/402 or eligible transient failure from that caller bearer therefore returns directly even when a stored sibling is available. Preserve enough request-scoped selection origin to retry with __main__ excluded, while still refusing durable health/affinity ownership for the caller credential.
Also fix the current strict-type mismatch around an absent quota scope and strengthen the regression to compare the exact caller bearer sent upstream, not only negative non-equality assertions. This is an authentication boundary, so keep it unmerged until those paths, focused recovery tests, exact-head CI, and explicit security review are green.

Refreshed this branch onto the current Three shards fail, and every failure is the same sentence: something that used to resolve to a pool account now resolves to
That is the title of this PR happening. Letting a request-owned main bearer take part in pool ordering means it can win an ordering that several existing contracts assume it can never enter, including the hard-lock path, which is a security-relevant one rather than a fixture detail. The failures are therefore the interesting output of the change, not an obstacle in front of it: each one names a place where the intended behavior has to be stated deliberately or excluded.

Summary
In Pool mode with the Codex app signed in as the main login and stored accounts added alongside it,
automatic placement never picked main. Every unpinned request went to a stored account whatever the
usage numbers, the strategy or
codexAccountPrioritiessaid, and main served only when pinned orwhen no stored account could be selected at all.
The cause is one predicate.
resolveCodexAuthContexthands selectionisMainAccountTokenLive: () => preserveRequestOwnedMainPinwhenever the request carries main's ownforwardable bearer. That value answers a different question — is main the effective manual pin with
headroom — so for an unpinned request it is false,
codexAccountUnusableReasonreturnsmain_credential_unavailable,getEligiblePoolAccountsnever lists main, and the strategy comparesonly the stored accounts. Main was still reachable afterwards through
resolveCallerOwnedMainContext,but only as the fallback when nothing else was selectable, so a pool with one stored sibling degraded
to "stored account until it cannot serve, then main".
The fence that predicate sits behind is correct and is kept: a request carrying its own main bearer
must not read or reconcile the stored
auth.json. But that same bearer is what would be forwarded ifmain were selected, so it is main's live credential for this request.
requestOwnedMainCredentialIsLivenow answers from the credential the request actually carries, and main is compared against the stored
accounts on the operator's own ordering. When selection names main, the request returns
resolveCallerOwnedMainContext()immediately — before any physical claim, token refresh ormaterialization — so nothing reads, reconciles, primes or cools the stored profile, and the
request-owned credential still owns no affinity, entitlement or health state.
Deliberately unchanged:
modelEligibleAccountIds, because its roster isdiscovered from the stored credential this request may not read, so candidacy alone cannot
manufacture a grant. That set currently holds one non-flagship slug, so it does not affect the
models in the report.
identity rather than the credential. The new expression is monotone against the old one — an
effective pin answers exactly as before — so the only behavior added is the unpinned case.
nativeMainSelectionOnly. Still derived from the drain alone.The predicate is shared rather than copied, for the reason
poolStateEligibleis: preview exists topredict the resolution, and a preview that scores main differently hands subagent fallback a different
account than the one that serves. Final authentication and both preview builders in
request-prepare.ts(initial and post-decryption recovery) call the one exported expression, which isthe divergence class #4850 closed.
The behavior change a reviewer should look at first
Because main is now scored, main's own recorded model failure reaches subagent fallback, where it was
previously invisible.
responses-preview-main-read-fence.test.tsencoded the old answer in"ownership alone leaves selection-only off", whose assertion was
finalAuth=pool-awith thephysical file deleted. That case is replaced by the two directions of the new contract rather than
relaxed, and both keep the deleted
auth.json, so any path that still needed the physical credentialtakes an ENOENT instead of a quiet fallback.
This touches credential selection, so it needs the explicit security review
MAINTAINERS.mdrequiresfor auth paths. I am not merging it.
Closes #5019
Verification
Local verification was not run: this lane forbids any local suite, focused test, typecheck, build,
install, or
ocxinvocation, so hosted CI is the executable verification for this change. What wasdone instead is a static trace of the full chain —
resolveCodexAuthContext→nativeMainReadsForbidden→isMainAccountTokenLive→codexAccountUnusableReason→getEligiblePoolAccounts→ strategy →resolveCallerOwnedMainContext— against the base commit,plus a check that PRs #4921, #4676 and #4935 did not already alter it (they did not: #4676 contains no
file in this path, and #4935's cohort keying never applies to a request-owned credential because
poolStateEligibleexcludes it).tests/responses/responses-preview-main-read-fence.test.tsnow covers both directions: main isselected and served from the caller's bearer with the model untouched and the denial-cache
validator never running, and a failure recorded against main reaches subagent fallback. The
discriminator in the first case is that the recorded failure belongs to
pool-a, so leaving themodel alone is only possible if preview scored main.
