+// Regression probe for issue #7151: OpenRouter (and every other
+// `passthroughModels` provider — requesty, dgrid, agentrouter, charm-hyper,
+// etc.) never appears in the Hermes Agent role model picker.
+//
+// Root cause: <ModelSelectModal> derives a passthrough provider's model list
+// from the `modelAliases` prop (ModelSelectModal.tsx groupedModels →
+// buildPassthroughAliasModels(modelAliases, providerId)). When `modelAliases`
+// is `{}` (the component default), that helper returns `[]` and the provider
+// group is skipped entirely — see modelSelectModalHelpers.ts. Every sibling
+// CLI tool card (Codex, Claude, Cline, Kilo, Droid, OpenClaw, Antigravity)
+// fetches `/api/models/alias` and passes the result through, but
+// HermesAgentToolCard never does, so OpenRouter's managed-available-model
+// aliases (synced automatically after the connection is tested — see
+// syncManagedAvailableModelAliases in src/lib/providerModels/managedAvailableModels.ts)
+// are invisible to it.
