sgeboers aa2f66ac9f feat(analysis): fetch real MP metadata, fix anchor axis for party-level actors 
- fetch_mp_metadata: use real OData URL with pagination (1200 records, 5 pages)
  uses Fractie.Afkorting not NaamNL for abbreviation matching
  skips Verwijderd=true records
- upsert_mp_metadata: keep most recent membership (prefer active over ended,
  then higher Van date) so current party affiliations are not overwritten by historical
- compute_anchor_axis: anchor directly on party-level SVD entities (GroenLinks-PvdA etc)
  before falling back to mp_metadata individual MP lookup
- test_fetch_mp_metadata: fix mock for timeout kwarg + pagination + Afkorting field
- Generated anchor axis HTML for 2025-Q2 through 2026-Q1 in outputs/

sgeboers 5ad83ef1be fix(tests): update test_extract_mp_votes for party-level actor inclusion 
New extract_mp_votes behavior inserts all actors (party + individual MPs),
not only comma-name MPs. Test now validates both types and their party column.
Also adds generated HTML visualizations (political axis x5 windows + trajectories).

sgeboers f2a831dfcf feat(pipeline): add orchestrator CLI, analysis modules, and ActorFractie ingestion 
- pipeline/run_pipeline.py: CLI orchestrator for all 5 pipeline phases with
  --dry-run, --skip-*, --window-size, --svd-k, --start/end-date flags
- analysis/{political_axis,trajectory,clustering,visualize}.py: PCA/anchor
  ideological axis, MP drift trajectories, UMAP + KMeans clustering, Plotly HTML output
- api_client.py: capture ActorFractie per individual MP vote (comma in ActorNaam)
  into mp_vote_parties dict on each motion
- database.insert_motion: auto-insert mp_votes rows with party affiliation for
  newly ingested motions when mp_vote_parties is present
- Add scikit-learn to pyproject.toml for KMeans clustering
- tests/test_run_pipeline.py: window generation, dry-run, skip-all paths
- tests/test_analysis.py: PCA axis, anchor axis, trajectory drift, KMeans

sgeboers a36e6cba4e feat(pipeline): implement parliamentary embedding pipeline MVP 
- Add 4 migration files: mp_votes, mp_metadata, svd_vectors, fused_embeddings
- Extend database.py with 5 new helper methods and table init
- Add pipeline/ package: extract_mp_votes, fetch_mp_metadata, text_pipeline,
  svd_pipeline (with Procrustes alignment), fusion
- Add full test suite (17 tests) covering all pipeline modules and migrations
- Fix Procrustes alignment bug: scipy scale is a norm value, not a multiplier
- Fix DuckDB date type handling in test assertions (datetime.date vs string)
- Remove duckdb.py shim; tests now run against real duckdb + scipy via uv
