Sven Geboers	daa22c5e2b	feat: complete parliamentary embedding pipeline with full historical coverage ... - Add fused (SVD + text) embedding pipeline for annual windows 2016-2026 - Fix store_fused_embedding duplicate bug: DELETE before INSERT (idempotent) - Add --text-batch-size CLI flag to run_pipeline.py (default 200) - Add explicit --start-date/--end-date to download_past_year.py - Backfill mp_votes for all motions (party-level votes, 111k new rows) - Add similarity cache recompute: 212k rows across 9 annual windows - Improve ai_provider retry logic, text_pipeline batching - Improve analysis/political_axis PCA handling and visualizations - Add diagnostic/utility scripts: compare_svd, generate_compass, inspect_axis, etc. - Untrack data/motions.db (3.6GB binary), add to .gitignore with outputs/ - Update continuity ledger with full session state	1 month ago
Sven Geboers	a78bee9b0a	feat(similarity): add precomputed similarity cache, fix fusion N+1, add 429 retry ... - Add similarity/ package (compute.py, lookup.py) with numpy-based pairwise cosine similarity and cached lookup - database.py: create embeddings + similarity_cache tables in _init_database(), add store_similarity_batch/get_cached_similarities/clear_similarity_cache helpers - pipeline/fusion.py: replace N+1 per-motion embedding SELECT with single bulk JOIN using DuckDB QUALIFY window function - ai_provider.py: retry HTTP 429 with Retry-After header support - migrations/2026-03-22-add-similarity-cache.sql: make executable - Add tests for similarity compute, db helpers, and 429 retry (34 pass, 2 skip)	1 month ago
Sven Geboers	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/	1 month ago
Sven Geboers	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 Ref: thoughts/shared/plans/2026-03-21-parliamentary-embedding-pipeline-plan.md	1 month ago
Sven Geboers	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 Ref: thoughts/shared/plans/2026-03-21-parliamentary-embedding-pipeline-plan.md	1 month ago
