Package ingest is the WRITE side of the catalog: it takes one data source's SDL and turns it into the physical model the catalog storage persists.

Package store is the entity-storage catalog provider (design 034).

Package llm implements LLM data source types for AI model providers.

Package ratelimit provides request and token rate limiting for LLM sources.

Package reports implements design/039: a report is a pure function of (spec, variables, identity).

Package ui holds the embedded browser assets of the visualization stack — the widget page, the shared JS core and the ECharts runtime — and exports them as bytes: go:embed does not cross package borders, so everything that inlines these assets into a page (pkg/mcp for the widget builds, pkg/mcp/reports for the report document) imports them from here.

Package viz is the visualization core shared by the MCP viz tools (pkg/mcp) and the report renderer (pkg/mcp/reports): the canonical data contracts — flat rows and KPI cards — the chart/column specs, the caps, and the query+jq pipeline that feeds them (query.go).
