A full SQLite sync may seed a newly inserted publisher's niche; it never updates an existing publisher's niche. This prevents the next OVH sync from overwriting homelab classification. The first OVH run used `sync --seed-niches`: only non-null source labels can fill target rows whose niche is still null. The target predicate is enforced in the database UPDATE, so newer homelab labels survive. `--niches-only` is reserved for a separately reviewed correction and may replace or clear labels; no automatic job uses it. -The full sync now includes measured homepage title, description, h1, language, and source under `last_check_evidence.enrichment.homepage`.
