Model

A Model is a pure data object describing what data looks like and where it goes. It does not contain execution logic — that lives in a separate execute function that receives the model as a parameter.

The Model itself is the top-level container. Its sub-objects each have their own page:

• Temporality — the model's time axis (TEMPORAL / TIMELESS), plus the materialization (table / view) choice
• Target — where data lands (table, schema, columns, write mode)
• Staging — optional staging table on Target
• Contract — historical envelope for backfill mode
• Batch — chunk size, lookback, retries
• Curfew — wall-clock hours/days the model must not run
• State — per-model state tracking
• Upstream — the model's inputs (list[Source]): gated upstreams + ungated sources
• Tagging — controls which auto-derived tags get added to the model
