Deduplication:
- Identified 18 motion pairs with identical body_text and externe_identifier
- Kept the lower ID (first inserted) from each pair
- Cascaded deletes: 18 motions, 18 embeddings, 28 svd_vectors, 23 fused_embeddings
- motions table: 28172 → 28154, zero body_text duplicate groups remaining
SVD analysis:
- Regenerated top_svd_top_motions.json for window=2025 with clean data
(7424 vectors, down from 7430)
- 100 unique motions across 10 axes, no title or ID duplicates
- De Vos huiseigenaren motie no longer appears twice in axis 3
- Regenerated top_svd_top_motions.json for window=2025 with strict
cross-axis deduplication: 100 unique motions across 10 axes (10 per
axis, zero overlap), sorted by absolute SVD score
- Added SVD_THEMES dict to build_svd_components_tab with Dutch-language
theme label and political-polarisation explanation for each of the 10
axes (e.g. 'Confessioneel-conservatief vs. seculier-progressief')
- Selectbox now shows 'As N — <theme>' instead of bare component number
- Each selected axis shows an info banner with the full explanation
- Motion list buttons show ▲/▼ to indicate positive/negative SVD loading
- Translated UI strings to Dutch for consistency
- 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
