Two scenarios: freshly-ingested 2-doc KB (stats reflect counts +
last_ingest_at populated) and empty-but-initialized KB (counts zero,
last_ingest_at None). The empty case runs ingest_with_config over an
empty workspace dir to seed kebab.sqlite before calling schema_with_config,
since open_existing (used internally) returns NotIndexed if the DB is absent.
