ingestion
Offline batch pipeline (never part of the live ai-service request path):
extract -> segment -> chunk -> embed -> load. Parses
data/raw/duoc-thu-quoc-gia-viet-nam-2018.pdf into per-drug, per-section
chunks and upserts embeddings into Qdrant. Run via
python -m ingestion.cli run --pdf data/raw/duoc-thu-quoc-gia-viet-nam-2018.pdf
(once implemented).
