From b35c78c6940fa0f9a420dce8ca8eabfdbc3efeac Mon Sep 17 00:00:00 2001 From: Bryan Bartley Date: Fri, 29 May 2026 15:45:59 -0500 Subject: [PATCH 1/3] fix(models): suppress placeholder API keys, badge subscription providers, hint on 401 (#4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the loop on the 'demoed deck rejected a viewer's prompt with 401' bug from issue #4. Root cause: the SDK ships overlapping model namespaces — `openai` (uses `OPENAI_API_KEY` against platform.openai.com) and `openai-codex` (uses the ChatGPT Plus/Pro OAuth subscription). Both expose `gpt-5`, `gpt-5.1`, `gpt-5.2`, etc. A common `.env.example` placeholder like `OPENAI_API_KEY=sk-your-...here` in the viewer's environment was enough for the SDK's `hasConfiguredAuth` to mark the openai-provider variant as 'available' (it only checks 'env var non-empty'). The picker then surfaced `openai/gpt-5` next to `openai-codex/gpt-5` with nothing distinguishing them; the click routed through the API-key path; OpenAI rejected the placeholder with 401. Three deck-side fixes: A. Suppress placeholder API keys when computing model availability. New `apps/server/src/credential-quality.ts` with `looksLikePlaceholderKey` — matches `sk-your-*`, `sk-XXXX`, `your-api-key`, ``, `changeme`, unsubstituted shell vars, all-X strings, and length-too-short-to-be-real keys per provider prefix family. Wired into `modelInfoFromSdk` in bridge/in-process.ts. OAuth credentials in auth.db (`isUsingOAuth`) always bypass the check — they're orthogonal to env values. B. Badge subscription providers in the model picker. Added `isSubscription?: boolean` to the ModelInfo protocol type, computed server-side from the SDK's `getOAuthProviders()` list, rendered as a green 'subscription' badge in ModelPickerModal. Users can now see at a glance which `gpt-5` row uses their ChatGPT Plus subscription vs which uses an API key. C. 401-recovery hint. Bridge listens for SDK `notice` events with `level: 'error'` and an auth-shaped message (401, 'incorrect api key', 'unauthorized', etc.). When the current session model is on an API-key provider AND a subscription provider carries the same model id with a real OAuth credential, fires a deck notification telling the operator to switch. Tests: 6 new credential-quality tests (44 assertions). Full server suite still green (167/167).

That list is broader than 'consumer subscription'; it includes: - Local runtimes: ollama, lm-studio, vllm - Gateway services: litellm, kilo, cloudflare-ai-gateway, zenmux - API-tier providers: cerebras, fireworks, together, huggingface, nanogpt, nvidia, venice, moonshot, ...

When the SDK adds a new subscription-style provider upstream, add it here. Also drops the `getOAuthProviders` import that's no longer used and the broken memoization layer (set is now a module-level const).

Three related fixes to the OAuth route's flow lifecycle: 1. Server-side 5-minute timeout per flow. The SDK's own DEFAULT_TIMEOUT (5 min) only fires on the loopback callback listener — it never fires on flows driven by `onPrompt` (e.g. ollama's 'where's your local endpoint?' prompt). Result: closing the ollama OAuth modal without typing a URL leaves the SDK's login promise pending forever, the flow stays in the deck's `flows` map, and every subsequent `POST /:provider/start` returns 409 'already in progress' until the deck process restarts. The deck now schedules its own `setTimeout(... OAUTH_FLOW_MAX_MS)` per flow that force-cancels and broadcasts `oauth_failed` if the flow hasn't naturally completed in time. Cleared on natural completion via `.finally()`. 2. Stale-flow eviction on `/start`. Defensive belt-and-suspenders: if a duplicate `start` arrives and the held flow is past OAUTH_FLOW_MAX_MS, the timer should already have fired — but evict it inline here too so a wedged flow (e.g. timer somehow lost, event loop starved) can't block new attempts indefinitely. 3. `cancel` cleans up promptResolvers too (latent bug). The pre-fix `cancel` handler only aborted the AbortController and rejected `manualCode`. It never touched `promptResolvers`, so cancelling a flow blocked on an `onPrompt` (ollama's endpoint input) left the SDK's promise pending and the flow effectively un-cleaned. Factored the teardown into a single `abortFlow(flow, reason)` helper used by all three paths (cancel, timeout, stale eviction). The helper: - Aborts the SDK AbortController - Clears the lifetime timer - Rejects `consentReady` and `manualCode` deferreds - Resolves all pending `promptResolvers` with empty string (rejecting would surface as an uncaught error inside the SDK's onPrompt caller) - Removes from both `flows` and `flowsById` maps - Is idempotent — second call is a no-op Tests: 6 new tests for the cleanup helper covering pending-deferred rejection, promptResolvers drain, AbortController abort, idempotency, and survival across a throwing resolver.
