v2.3 is heavy on infrastructure but visible at the edge: faster events, citations in reports, and the first vertical playbook beyond the generic agents.
What shipped
- NATS replaces gRPC for the internal event bus. Usage events, chat events, and agent state changes now flow through NATS instead of point-to-point gRPC calls. Lower latency, simpler ops, easier to add new event types.
- Web search citations in PDF reports — when an answer pulled from web search, the resulting PDF now lists the sources at the end with timestamps. No more "where did this number come from" follow-up questions.
- Active-Wellness playbook skill — first vertical-specific playbook. Generates a structured deck for retirement-community / active-adult site evaluation, with Hubexo demographic data integration.
Why it mattered
The NATS migration is invisible to users but important: it lets us add new event-driven features (live notifications, webhooks for external systems, custom integrations) without N+1 scaling problems.
Web citations close the credibility loop on shareable outputs. A PDF report you can hand to a client is only useful if the client can verify it. Now they can.
The Active-Wellness playbook is the template: vertical playbooks let us deliver something a generalist agent can't — domain-specific structure, data sources, and decision frameworks. More verticals coming.
