Guest-facing Lucia has crossed from future concept into implemented live-development infrastructure, but production readiness still requires verification, persistence, Admin review, security, and Eval Labs hardening.
Current Implemented Baseline
Current product milestone:hello-lucia/lucia-guest-agent main at source commit 826a6a14e2fa95bfd60c8008fb0cdc9d846b4231. The production override and source fallback are both gpt-5.6-sol, and live verification returned gpt-5.6-sol from the provider.
Lucia Engine currently uses the same model name through a separate configuration and verification boundary. Neither surface inherits the other’s model selection or runtime proof.
The model-only upgrade left prompts, verification flow, routing, schemas, and the core SSE events start, token, cta, meta, and done unchanged. This is implemented live-development state, not a broader production-readiness claim.
