Define the schema
Zod v4 is the source for runtime validation, TypeScript types, and the generated OpenAPI 3.1 contract.

FENICE
An AI-native foundation for production systems.
FENICE starts where repeated backend setup usually ends: typed contracts, authentication, agent discovery, observability, adapters, validation, and a guarded AI builder already working together.

Position / 01
Start where backend boilerplate ends.
AI-native should not mean a chat layer added after launch. In FENICE, schemas, documentation, agent discovery, observability, and guarded generation are part of the system contract from the beginning.
Foundation / 02
One contract, carried through the system.
Secure the path
JWT access and refresh flows, role checks, rate limits, timeouts, redaction, and adapter boundaries are built into the baseline.
Expose it to agents
MCP discovery and LLM-readable documentation let agents understand the API without a second, drifting integration layer.
Observe and approve
OpenTelemetry traces the system; AI-generated changes pass through planning, approval, scope checks, validation, and pull requests.
Platform / 03
Production mechanics are part of the starting point.
Typed API foundation
Hono, Zod v4, MongoDB, Mongoose, OpenAPI, and Scalar documentation share a deliberate contract.
Agent-readable by design
MCP discovery and Markdown API documentation make capabilities legible to both developers and agents.
Operational visibility
Structured logs, request correlation, OpenTelemetry, health endpoints, and WebSocket projection are present from day one.
Guarded AI builder
Natural-language changes are planned, approved, limited by scope policy, validated, repaired once, and proposed through a PR.
Current state / 04
A reusable foundation, not a hosted-product claim.

“Production-ready” describes the engineering baseline and validation discipline. FENICE is an open foundation to deploy and adapt, not a Formray-hosted SaaS service.
Build the product, not the same foundation again.
Clone the platform, inspect the decisions, and adapt the parts that belong in your own system.
