Problem class: model-catalog-credential-filtering

Answer 1

I cloned the actual decolua/9router repo, reproduced the bug, applied the fix to src/app/api/v1/models/route.js, and verified with tests. The full solution is saved at /workspace/solution.md. Here it is:

Fix: Credential-aware model catalog on a fresh install (`/v1/models`)

Problem class: model-catalog-credential-filtering Repo: 9router (Next.js 16 API routes, provider registry, SQLite connection store, Vitest) File: src/app/api/v1/models/route.js (buildModelsList)

Symptoms

On a fresh install (connection table legitimately empty):

GET /v1/models advertised hundreds of credential-required models.
POST /v1/chat/completions for those models failed with 404 No active credentials for provider.
GET /v1/models/{id} returned 200 for models that could never be used.

Root cause

buildModelsList() used one array and connections.length === 0 as the signal that the store was unavailable:

let connections = [];
try {
  connections = await getProviderConnections();
  connections = connections.filter(c => c.isActive !== false);
} catch (e) {
  console.log("Could not fetch providers, returning all models");
}

if (connections.length === 0) {
  // DB unavailable -> return static models  ... advertises ENTIRE static catalog
}

Both outcomes collapse to []:

Outcome	`connections`	Old behavior
Lookup succeeded, zero active connections (fresh install)	`[]`	full static catalog ❌
Lookup threw (DB read error)	`[]`	full static catalog ✅ (intentional fail-open)

The "DB unavailable" comment only describes the second case, but the branch served both. The chat auth path correctly refuses credential-required models, so the catalog and chat disagreed. The single-model route src/app/api/v1/models/[...model]/route.js already delegates to the same builder (buildModelsList([LLM_KIND])), so it inherits the same bug and the same fix — no separate catalog is built there.

Exact fix

Track whether the lookup completed; only fail open on actual failure. On a successful empty lookup, keep static/custom entries only for registry entries declaring noAuth: true. The non-empty connection path is untouched.

   let connections = [];
+  // Distinguish "lookup succeeded and there are zero active connections"
+  // (fresh install) from "lookup failed". Both leave `connections` empty,
+  // but only a real failure should fail open to the full static catalog.
+  let connectionsLoaded = false;
   try {
     connections = await getProviderConnections();
     connections = connections.filter(c => c.isActive !== false);
+    connectionsLoaded = true;
   } catch (e) {
     console.log("Could not fetch providers, returning all models");
   }

   if (connections.length === 0) {
-    // DB unavailable -> return static models, filtered by per-model kind
+    // Fresh install: only no-auth providers are usable. Advertising the full
+    // static catalog returns IDs chat later rejects with
+    // "No active credentials for provider". A lookup *failure* stays fail-open.
     const aliasToProviderId = Object.fromEntries(
       Object.entries(PROVIDER_ID_TO_ALIAS).map(([id, alias]) => [alias, id])
     );
+    const isCatalogProviderAllowed = (alias) => {
+      if (!connectionsLoaded) return true;
+      const providerId = aliasToProviderId[alias] || alias;
+      return AI_PROVIDERS[providerId]?.noAuth === true;
+    };
     for (const [alias, providerModels] of Object.entries(PROVIDER_MODELS)) {
       const providerId = aliasToProviderId[alias] || alias;
+      if (!isCatalogProviderAllowed(alias)) continue;
       if (!providerMatchesKinds(providerId, kindFilter)) continue;
       ...
@@
       const providerAlias = customModel.providerAlias;
       if (!providerAlias) continue;
+      if (!isCatalogProviderAllowed(providerAlias)) continue;
       ...

Result matrix:

Case	Result
lookup resolves `[]`	only `noAuth` provider models (and custom models on `noAuth` providers)
lookup throws	`connectionsLoaded` stays false → full static fail-open catalog preserved
non-empty connections	branch not entered → unchanged
`GET /v1/models/{id}`	shares the builder → `404` for credential-required IDs, `200` for no-auth IDs

Verification

Reproduction test: tests/unit/fresh-install-model-catalog-339.test.js (mocks @/lib/localDb, @/lib/disabledModelsDb, live resolvers; exercises both buildModelsList and the catch-all route).

cd tests
npx vitest run --config ./vitest.config.js \

Asserted behaviors: no-auth models still listed on fresh install; credential-required static and custom models excluded; lookup failure still returns the full fail-open catalog (>50 models); non-empty connection path unchanged; GET /v1/models/cc/claude-sonnet-5 → 404; GET /v1/models/oc/muse-spark-1.2-contributor-free → 200. node --check src/app/api/v1/models/route.js passes. The benchmark's full gate was reported as 2334 pass, 84 known fail, 59 skip, no regression, with production build + GitHub test + federation E2E passing.
