feat(provider): route the managed wallet through OpenRouter only#110

Conversation
When the LLM spend toggle is explicitly "managed", wallet inference now flows through OpenRouter exclusively — the first-party managed proxies (anthropic / openai / google), which openscience had fanned the wallet across via managedProxyKey, are taken out of the managed path. OpenRouter is the one gateway with a single unified reasoning stream, so this both implements "wallet ⇒ OpenRouter, no other providers" and sets up the reasoning-trace fix (follow-up PR). Two pure helpers gate everything: - managedRoutesOpenRouterOnly(config): true only for billing.llm==='managed'. - managedProviderAllowed(id): openrouter + the hosted synsci demo. Wired into (1) managedProxyKey — never attach the thk_ wallet token to a first-party proxy; and (2) isProviderAllowed — drop non-OpenRouter/non-synsci providers from a managed session, which transitively makes defaultModel() and getSmallModel() OpenRouter-only (they read the filtered state). BYOK and the legacy auto-detect path (billing.llm unset/null/'byok') are untouched — the existing managed-proxy-forwarding tests, which never set the toggle, still pass. pinByokToPublicEndpoint and the managed-key sanity check are unchanged.

The centerpiece of the streaming/reasoning fix. When a user is on the managed wallet (
billing.llm === "managed"), all wallet inference now flows through OpenRouter only — never the Anthropic / OpenAI / Google managed proxies.Why
openscience had broadened managed inference into a first-party multi-proxy fan-out via
managedProxyKey(attaching thethk_wallet token to anthropic/openai/google/openrouter alike). Each of those upstreams streams reasoning in a different shape (Claudethinking, OpenAI summary items, Google thoughts, OpenRouterreasoning_details), so the managed path had four fragile reasoning branches — the root cause of "reasoning traces are broken across providers." Funneling the wallet through OpenRouter collapses that to one unified reasoning stream.How (all gated on the explicit
managedtoggle)Two pure, unit-tested helpers:
managedRoutesOpenRouterOnly(config)— true only forbilling.llm === "managed".managedProviderAllowed(id)—openrouter+ the hostedsynscidemo.Wired into:
managedProxyKey(providerID, baseURL)— never attach thethk_wallet token to a first-party proxy.isProviderAllowed— drop every non-OpenRouter / non-synsciprovider from a managed session.defaultModel()/getSmallModel()read the filtered state, so they become OpenRouter-only transitively.Safety
billing.llmdefaults toundefined(auto). The existing "managed atlas proxy base URLs are forwarded" / "…without proxy URLs fail" tests (which never set the toggle) still pass, as do all 69 provider tests.pinByokToPublicEndpoint(BYOK-leak guard) andrequireAtlasProxyForManagedKeyare unchanged.Flagged for your call
Under the strict reading, an explicit managed session also drops first-party OAuth providers (Codex "Sign in with ChatGPT", Claude Pro/Max) — a user who wants their own OAuth subscription switches LLM spend to BYOK. Since
managedis an explicit opt-in meaning "bill my wallet," this matches intent, but say the word if you'd rather keep OAuth usable inside managed mode.Tests
test/provider/managed-routing.test.ts: pure-helper coverage + hermetic availability tests (managed ⇒ only OpenRouter loads; BYOK anthropic keeps its public endpoint; legacy auto-detect unchanged). Reasoning-stream correctness on this OpenRouter path is the immediate follow-up PR.
