    🚀 TopicWatchdog – Week 3: Stable Topics with BERTopic

    KMeans worked, but cluster IDs kept jumping across retrains. This week I added a Python BERTopic stage with a BigQuery registry → stable topic IDs!

    🟢 UMAP + HDBSCAN
    🟢 Stable IDs via registry
    🟢 Auto-labels with Gemini
    🟢 Looker Studio dashboards

    📊 3,802 topics → 2,472 mapped, top clusters: migration, economy, climate, politics.
