requirements.txt

# ============================================================================
# Top-level requirements for the Prism demo workshop image.
# ============================================================================
# This file is the union of all Python dependencies used anywhere in this
# repository: the data-loader pipeline (schema-data/) AND the notebooks
# (notebooks/). Use this to build the workshop image.
#
# Smaller-scoped manifest:
#   - schema-data/requirements.txt: just the data-loader pipeline runtime.
#     If you only need to run prism-seed.py / prism-ingest.py / the chunks
#     export/import scripts, install from that file instead.
#
# Pinning policy: exact versions. The langchain / langgraph ecosystem
# changes API surface frequently (langgraph 1.0 was a breaking release in
# late 2025). Pin and bump deliberately; do not let pip resolve to "latest"
# at image build time.
