Vercel + Lovable, GPT-5.6 multiagent, curl security patch — Dev Signal #64

Short summary

Dev Signal #64 covers four developments: Lovable projects now auto-deploy to Vercel via Nitro with zero config, OpenAI's GPT-5.6 introduces Sol/Terra/Luna tiers for cost-aware multi-agent routing, curl releases 18 CVEs requiring immediate patching for auth state leaks and connection reuse bugs, and ByteDance's Seedream 5.0 Pro adds text-aware image generation through Vercel's AI Gateway. Each item includes a ship/evaluate/patch verdict.

• •Lovable→Vercel zero-config auto-deploy via Nitro eliminates the deployment gap for AI-generated apps
• •GPT-5.6 tiers (Sol/Terra/Luna) enable task-complexity-based routing but hallucination rates exceed GPT-5.5 max
• •curl 18-CVE release is a mandatory patch: auth state leaks across proxies, mTLS mismatches, HTTP/2 use-after-free
