OpenRouter chat drift leg (cost-safe live canary + envelope triangulation)#333
Merged
Conversation
Add cost-safe drift coverage for the shipped OpenRouter chat/router mock
(src/openrouter-chat.ts), which had none. Mirrors openrouter-video.drift.ts:
1. LIVE canary (FREE, OPENROUTER_API_KEY-gated): GET /api/v1/models (catalog
metadata only, never a paid completion) — asserts the author families
aimock mirrors (openai/anthropic/google) are still present and the
per-model object schema has not drifted.
2. Static envelope shapes (no key): drive the real handler over
POST /api/v1/chat/completions and triangulate the non-streaming envelope,
a streaming chunk, the final usage-bearing chunk (cost/cost_details/
service_tier), and the OpenRouter error envelope {error:{code,message}}
against hand-authored conformant exemplars.
Adds listOpenRouterModels() to providers.ts and registers the
'openrouter-chat' surface in surface-registry.ts.
