Sven Geboers	364c312076	fix(right-wing): update DB with latest motions, fix DROP TABLE bug, score all missing 2D ... - Fetched 276 new motions from Tweede Kamer API (2026-04-23 to 2026-05-31) - Fixed classify_motions.py: DROP TABLE → CREATE TABLE IF NOT EXISTS - Restored derived columns (centrist_support_strict, category, etc.) via migration - Scored 180 missing motions in extremity_scores_2d (now 3,049 total, 0 missing) - Re-ran temporal trajectory with updated data (inflection: 2024-Q2)	3 weeks ago
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	3 months 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)	3 months 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	3 months ago
