LATTICE FastAPI Endpoint Authoring

What problem does it solve?

It prevents API contract drift between the FastAPI sidecar implementation and the repository’s canonical metadata, which otherwise breaks dependent systems and causes hard-to-debug runtime failures.

Core Features & Use Cases

• Contract-first route authoring: Add routes only via the pixeltable FastAPI sidecar and ensure the declared endpoint table stays synchronized.
• JSON-only responses enforcement: Guarantee routes return JSON by banning HTML/file/redirect patterns.
• Live endpoint count validation: Detect and correct endpoint count drift against meta/API.md and surface architecture counts in meta/ARCHITECTURE.md.
• Operational verification: Confirm sidecar health, validate Unix socket connectivity in production, and run the scoring script for drift/worker health checks.

Quick Start

Use the LATTICE API skill to add a new FastAPI route under pixeltable/service/routes/<section>.py, then update meta/API.md and meta/ARCHITECTURE.md in the same commit.
