What's in it

Foreman scrapes every London borough's planning register from planit.org.uk, then scores each application for housing relevance — is this actually about building or changing homes, not a satellite dish or a tree preservation order. Foundations is the slice that clears that bar: application type and size, decision and timing, dwelling counts, consultation activity (comments, documents, statutory notice days), agent and case officer, and location. See About for how the pipeline works end to end.

Same housing_relevance_score > 0.9 boundary everywhere — the CSV, the Parquet file, and the API all agree.
