Revise SVD_THEMES labels based on TF-IDF analysis of top 50 motions
per component (pool size: current_parliament). Manual review of motion
titles ensures labels reflect actual parliamentary content rather than
party position semantics.
Key corrections:
- Axis 1: fiscal/economic policy vs social welfare + international rights
- Axis 4: active international engagement vs restraint
- Axis 5: pragmatic financial support vs progressive individual rights
- Axis 6: fossil fuels/financial incentives vs climate/intl rights
- Axis 7: practical-administrative vs idealistico-procedural (kept)
- Axis 8: European defense cooperation vs domestic socioeconomic policy
- Axis 9: concrete-administrative vs systemic reform
- Axis 10: citizen protection vs government regulation
Subagent analysis caught that axes 5 and 6 are NOT the same
(Nationale soevereiniteit) — manual motion review confirms distinct
content for each. Axes 1, 5, 6 had completely wrong labels.

Cleanup performed by assistant: removed generated caches and stale files: __pycache__, *.pyc, .pytest_cache, .ruff_cache, dummy/, test.py, read.py, reset.py, fix_database.py, thoughts/thoughts/, .github/workflows/mindmodel-validate.yml. No push performed.
- 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
