Prevent large-context aliases from bypassing native combo shadows.
The large entry is emitted before nativeAliasesBySlug is checked. A native combo that shadows gpt-6-sol therefore does not suppress gpt-6-sol-900k, which can route directly to the native backend.
sourceSlugs also includes account-only slugs, so the current condition can emit bare -900k entries for those slugs. disabledModels is handled correctly by the later visibility pass and is not part of this fix.

Avoid rebuilding base entries when only variants are needed.
buildCatalogEntriesFromObservedState derives both the base and variant for every baseSlugs entry, then the merge discards every non-variant entry. Extract the variant construction into a shared helper that consumes the existing native entries.
This is redundant computation only. The policy claim does not hold: policy filtering occurs before baseSlugs is created, and the backfill loop adds only policy.nativeBackfillSlugs. Since accountSelectors is empty, the empty disabled-account set cannot emit account-qualified variants.

Do not synthesize large-context metadata for date-stamped native variants.
isNativeContextVariantBase accepts date-stamped Sol and Luna slugs, but nativeOpenAiContextTier performs an exact override lookup. It does not normalize those slugs to gpt-6-sol or gpt-6-luna. Therefore, a date-stamped -900k variant can reach nativeLargeContextLimits without tier evidence. With no configured cap or model/provider window, the fallback sets both values to 872_000. Configured positive caps can reduce that value, but they do not provide evidence for the fallback.
Return null when no tier exists. Also remove the separate /v1/models fallback, or the endpoint will continue to advertise 872_000 after the resolver returns null.

Validate modelMaxInputTokens instead of copying it through an any cast.
Line 299 copies (provider as any)?.modelMaxInputTokens unfiltered and always sets the key, even when the value is undefined. The other maps in this function go through positiveInt. The any cast also hides the typed contract on OcxProviderConfig. nativeLargeContextLimits filters the values later, so the current behavior is safe. The inconsistency is still fragile, and it changes the returned object's shape for every caller.

Move these mid-file import statements to the top of the module.
Line 464 imports ./context-variants, and context-variants.ts Line 1 imports ./metadata. That is a circular dependency. ESM hoisting makes it work today. If a top-level call to isNativeContextVariantBase is ever added during evaluation, it can reach an uninitialized binding. Put the imports at the top of the file. Better still, import isNativeContextVariantBase from ./native-models and define the suffix there, which removes the cycle.

Apply disabled and eligibility checks to account-qualified aliases.
visibleAccountNatives adds qualified base rows without disabledModels.has(qualifiedId). It also adds every qualified -900k suffix without checking eligibility, canonical provider routing, or disabled aliases.
gpt-6.1-sol-900k is not a recognized native variant. The router does not reject it during route construction. It removes the account namespace, keeps gpt-6.1-sol-900k as route.modelId, and therefore does not normalize it to a base model. The downstream provider may reject that literal model ID.

Update the visibleAccountNatives construction to check disabledModels for each
account-qualified base ID and alias, and add a large-context alias only when it
is not disabled, is an eligible native variant according to
nativeLargeContextLimits, and the configured provider uses canonical OpenAI
routing. Preserve the existing native-variant handling.

Remove the final scope filter for routed rows.
A routed row is admitted with listAllows(m.provider, m.id), but the final filter rechecks the published owned_by and id values. For example, a non-combo row with provider external and model gpt-6-sol is admitted by allowedModels: ["gpt-6-sol"], then can be rejected when its published ID is external/gpt-6-sol.
The combo-specific provider example does not apply: combo rows use m.provider === "combo" during the first check, so allowedProviders: ["external"] would already reject them. The final filter is still incorrect for routed rows whose published selector differs from the resolved route.

Remove the final listAllows filter from the routed-row construction near the
closing array expression; keep the earlier route-level admission check using
m.provider and m.id so published row fields do not override the resolved route’s
selection.

Rewrite the raw model for native context variants.
When route.nativeContextVariant is present, parsed.modelId becomes the wire model before the later route.modelId !== parsed.modelId check. Native routing already sets route.modelId to that wire model, so the check is false and _rawBody.model remains the requested -900k alias. The passthrough serializes the raw body without replacing model from parsed.modelId, so the upstream can receive the unsupported alias.

Update the nativeContextVariant branch to also replace model in parsed._rawBody
with route.nativeContextVariant.wireModel when the raw body is an object. Keep
parsed.modelId and _nativeContextModelId assignments unchanged so passthrough
requests send the wire model rather than the requested alias.
