Sub-apps used to call @google/genai from the browser, shipping an API key to every user. This proxies Anthropic through the server so the key stays server-side and AI spend is auditable per Clerk userId. - Clerk JWT required (no API-key fallback) - Per-user rate limits via shared KV (AI_RATE_LIMIT_PER_MIN/HOUR) - CORS limited to *.cotrackpro.com + localhost - Both Fastify (long-running host) and Vercel (api/ai/complete.ts) adapters - Input validated: messages shape, max turns, max total chars, max_tokens cap Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
