Reproducible GIS project

Turn the analysis into an inspectable project another analyst can execute without the conversation. Retain the user's chosen algorithm and stack unless they cannot meet a stated requirement; explain consequential changes before making them. Do not silently substitute a convenient proxy for the requested measurement.

When the user has dlt, Dagster, dbt, QGIS or Observable in their stack, read references/established-stack.md for ownership and integration boundaries. Preserve their chosen tools; retain source pins, GIS correctness and reproducible evidence. Do not duplicate their SQL, ingestion or scheduler definitions.

Compile or update the project
