Data Flow tab:
- Prominent "Generate data" button (500 / 2K / 10K) that inserts a fresh
burst of business rows into all source DBs on demand via a new
POST /api/federated/generate (fresh connections, safe alongside the
background streamer); result toast shows what was inserted, CDC streams it.
- "Scripts" button + a "View generation scripts" action on the Data Generator
node open a modal listing every generator script with full source, served by
GET /api/dataflow/scripts. Sources are the real files: the live streaming
generator (sliced live out of trino_federated.py) and the Airflow per-source
DAGs + Faker scripts (mounted read-only from infra/airflow into the API).
Knowledge Chat:
- New "Vector DB" explorer modal: shows the ChromaDB chunking config
(RecursiveCharacterTextSplitter 800/120, all-MiniLM-L6-v2, 384-dim, HNSW),
collections & documents, and the actual stored chunks with text, metadata and
an embedding preview (bars + values) so you can see exactly how files are
split and written as vectors.
Refactor: generator row-builders shared by the streamer and the on-demand burst.
