feat(doctor): warn when the Codex default model is not exposed by the proxy - #4963
Conversation
Codex starts every session on the root model pin in its own config.toml, and nothing compared that pin against the models this install exposes. When the two disagree, every turn fails and no surface says why: /api/startup-health returns restart-survivability facts only, and none of runDoctor's sections read a model id. ocx doctor now reports it under "Codex default model exposure", immediately after "Codex config compatibility" because both read config.toml. The exposed set is read rather than recomputed - the running proxy's GET /v1/models when one answers, otherwise the on-disk catalog's visibility: "list" slugs - so the CLI does not duplicate the entitlements snapshot, provider gather and account-selector expansion that build the live list. It reports three states, including undeterminable, so an unread set is never reported as a broken pin, and stays a warning: no recordDoctorFailure, no process.exitCode write, because a degraded-but-working install must not break a green pipeline. Also documents the retained-hide-row contract for disabled bare natives, which is deliberate rather than a defect: the row preserves real upstream metadata for a later re-enable, disabledModels is a catalog control that routing never consults, and a nativeAlias combo is the lever that omits the row outright.

When the configured pin is a disabled native model, this warning says the proxy does not serve it, but structure/catalog.md lines 120-125 and the new user documentation explicitly establish that disabledModels only removes the model from discovery and src/router.ts still routes it normally. Thus a working pinned session is diagnosed as broken and the operator is told to change configuration unnecessarily; report this as a catalog/picker exposure mismatch rather than claiming the route cannot serve the model.

If config.toml exists but cannot be read, such as during a permission or transient filesystem failure, this catch returns the same null used for an absent root model. collectDefaultModelExposure consequently reports an ok not_configured result instead of an undeterminable diagnostic, hiding the pin precisely when doctor cannot inspect it. Return a discriminated read result so read failures remain distinct from a successfully read config with no model key.

When /v1/models returns an array in which a row is malformed or uses an incompatible shape, the loop silently discards that row and still returns a successful Set; if the catalog fallback is unavailable, doctor can therefore emit not_exposed even though the discarded row may represent the configured model. This contradicts the helper's stated malformed-body contract and should degrade the surface to null/undeterminable rather than fabricate a negative verdict.

Separate model exposure from routing and dashboard visibility.
disabledModels hides a native model from public discovery, but it does not block routing. Replace “opencodex does not serve” with wording that says ocx doctor warns when the configured root model is not exposed.
The dashboard correction is reversed. src/server/management/model-rows.ts:89-113 retains disabled native rows so the management dashboard can re-enable them, while visibleNativeSlugs and /v1/models omit them. Update lines 139-142 to distinguish those surfaces. Do not change lines 259-260 to say the dashboard omits the model; those lines describe the shipped dashboard behavior. This keeps the page compliant with the docs-site/** requirement to document current behavior.

Summary
Closes #4646.
The issue makes three asks. One of them is a real defect; the other two describe
behavior that is working as designed, and this PR says so explicitly rather than
implementing them.
Ask 3 (no warning when Codex's pinned default model is not exposed) was the real
defect, and is fixed. Codex starts every session on the root
modelpin in its ownconfig.toml, and nothing compared that pin against the models this install exposes.Neither surface checked it:
/api/startup-healthreturnsreadStartupHealthverbatimand its whole input set is restart-survivability facts, and none of the sections in
runDoctorread a model id. When the pin and the exposed set disagree, every turn failsand no diagnostic points at the pin.
ocx doctornow prints a Codex default model exposure section immediately afterCodex config compatibility, since both read
config.toml. Three design points:snapshot, a provider gather and account-selector expansion; duplicating it in the CLI is
exactly the drift
formatStartupRoutingDetailandcomputeVersionSkewwere extractedto prevent. So doctor reads
GET /v1/modelsfrom the proxy it has already resolved viafindLiveProxy, and falls back to the on-disk catalog'svisibility: "list"slugs."not exposed" when it could not read the set — the install least able to answer (proxy
down, catalog never synced) is exactly the one a fabricated failure would mislead. Both
surfaces are consulted before any negative verdict, so an encoding or staleness
difference between them cannot be reported as a broken pin.
recordDoctorFailure(), noprocess.exitCodewrite. FAIL isreserved for an unusable surface; a quota-exhausted or disabled pin is degraded, not
unusable, and must not break a legitimately green pipeline.
StartupHealthis deliberately not extended.deriveStartupHealthis a pure function overmachine-protection inputs, the GUI narrows its status to a three-colour dot, and its result
is cached by a subprocess probe whose cache key knows nothing about
disabledModels— amodel fact cached on service-diagnostic freshness would go stale on the next quota change.
This PR takes the smaller change: doctor only, no new settings field.
Ask 1 (sync skips rewriting an existing catalog because the file exists) is false, and
implementing it literally would be harmful. There is no existence test in the write
decision. Sync regenerates the whole catalog from live state and byte-compares against
disk:
src/codex/catalog/retained-sync.tsbuilds the content and returnscatalogWritten: falseonly when the freshly computed bytes equal the bytes on disk —strictly stronger than the slug-set or hash comparison the issue asks for. The skip is
load-bearing, not an oversight: a no-op rewrite bumps mtime, the app-server staleness
classifier (#857) compares that mtime against each running Codex's start time, and since
#1407 a stale verdict silences opencodex's model guidance for that Codex's entire
lifetime. It landed on 2026-08-11 in
c7eec01ca4/642805c11e, a month before thereport, and is already pinned by
tests/codex-integration/codex-catalog-sync-hardening.test.ts.Implementing the requested drift trigger would re-break both issues permanently.
visibleNativeSlugsfilters disabled slugs out of/v1/modelswhile the catalogintentionally retains them as
visibility: "hide"rows, so the two sets are unequal bydesign and can never converge. A rewrite triggered on that difference would rewrite the
catalog on every single sync, forever.
Ask 2 (disabled native slugs persist as
visibility: "hide") is true, and is thedocumented, deliberate contract.
desktopAllowlistSuppressedNativeSlugsreturns an emptyset when no native-alias combo is configured, and the visibility assignment keeps the row.
Retention preserves real upstream metadata so re-enabling restores it instead of
synthesizing a guess, and several code paths depend on that recovery property, so the
emission default is unchanged. Most of the contract was already documented; what was
missing was the operator-facing consequence, now added to the English
codex-app-models.mdguide andstructure/catalog.md: a disabled-but-hidden native slugcan still be shown and picked in Codex Desktop, selecting it is not refused for being
disabled (
disabledModelsis a catalog control andsrc/router.tsnever consults it), anda
nativeAliascombo is the lever that omits the row unconditionally.What could not be verified statically. The reporter's captured body shows
catalogWritten: falsebut not therefreshOutcome/skippedReasonfield that woulddistinguish outcomes, so it is unknown whether their runs reached the byte-compare at all
or landed on an earlier discriminated refusal:
desired_disabledre-read under the writelock, a
nullfromrevalidateRetainedCatalogSync, a stale entitlement snapshot, or areadRetainedCatalogSyncpreflight refusal. All of those also reportcatalogWritten: false. The field that separates them isrefreshOutcome:"committed"withcatalogWritten: falseis the byte-identical skip described above, while"refused"means the run never reached the comparison. If the reporter can supply the fullresponse body, that distinguishes them.

Verification
Local verification was not run: this lane forbids running the local suite, typecheck,
build, install, or the
ocxbinary. Hosted CI is the executable verification for thischange.
Hosted CI jobs and tests that exercise it:
bun run teston Linux, Windows and macOS — specificallytests/codex-integration/doctor.test.ts(six new collect-style cases: no pin, exposed viaproxy, not exposed with the surfaces named, undeterminable, proxy-401 falling back to the
catalog, and a retained
hiderow not counting as exposure) andtests/codex-integration/native-model-toggle.test.ts(the ask-2 contract: hidden-but-retainedwithout an alias, omitted with one).

bun run typecheck(strict) on all three platforms.bun run structure:checkviatests/ci-workflows/structure-ssot.test.ts— thestructure/doc-map and ownership gate for thesrc/cli/andsrc/codex/edits.tests/ci-workflows/file-size-ratchet.test.ts— no touched file is in the baseline andnone approaches the 2000-line threshold.
bun run privacy:scan— the new code logs a model id and no credential; it sends noAuthorization header and reads no token.
tests/cli/cli-dispatch.test.tsandtests/cli/cli-json-contract.test.ts— the doctordispatch and exit-code contract, which this change deliberately does not alter.
Static correctness argument, since none of the above ran locally:
readConfiguredDefaultModelusesreadRootTomlString(toml, "model"), whose regex anchors^\s*model\s*=, somodel_provider = "..."cannot match it, and which stops at the firsttable header, so a
[profiles.*]override is not read as the root pin.defaultCatalogModels()returnsRawEntry[](Record<string, unknown>), which is exactlythe injected row type, so the catalog path needs no cast.
CODEX_HOMEnor the network. The existingrunDoctortests write no rootmodel, so thenew section returns
not_configuredbefore any fetch is attempted.src/cli/doctor.tsis dynamically imported only by thedoctordispatch branch, so thenew import adds no cost to other commands.
Not done, deliberately: translated locales of
codex-app-models.md(ko, ja, zh-cn, zh-tw,fr, ru, tr) are untouched. The change adds a new English subsection rather than altering an
existing claim, so no translation now contradicts the English source; they are simply less
complete, which is the normal state between translation passes.
Checklist
On the third box: the new code performs one unauthenticated loopback
GET /v1/modelsagainst the proxy doctor already resolved. It sends no
Authorization,x-api-keyorx-opencodex-api-keyheader and reads no token file, so it adds no credential surface. On anon-loopback bind
/v1/modelsrequires data-plane admission, which doctor deliberately doesnot hold; that 401 is handled as "this surface did not answer" and the on-disk catalog
answers instead. The request is bounded by an 8s
AbortSignal.timeout, and every failuremode degrades to a verdict rather than throwing out of the diagnostic. No
.github/file istouched.
