# Signals Scout Data Warehouse

> Focused Signals scout for PostHog projects importing external data into the warehouse. Watches the import side — external data sources, per-table sync schemas, webhook push channels, and materialized views — for the moments an import quietly stops keeping its promise: a source connection in Error, a schema Failed or stuck Running, silent staleness behind a green Completed status, a broken webhook push channel, a row-volume cliff, and failed materialized views. When armed imports are healthy, switches to the optimization lane: reads the per-team querylog table for recurring, multi-user query time and read-bytes concentrated on warehouse tables or repeated query shapes, filing materialization candidates and unused matviews as P3 suggestions. Files each validated import contradiction as an inbox report; otherwise writes durable memory and closes out empty.
