Sven Geboers	e478235c84	fix(overton): correct SVD axis interpretation, drop pass rate, synthesis rewrite ... - SVD axis 2 sign corrected: negative = nationalist (PVV -0.56, FVD -0.36), positive = kosmopolitisch (Volt +0.27). Centrists moved LEFT on both axes while right-wing moved further right culturally (+0.146 gap). 'Acceptance without conversion' named as unifying interpretation. - U1: Figure 1 merged to single panel, pass rate removed, 5 centrist_support lines - U2: Pass rate columns dropped from all breakpoint tables, PR narrative cut - U3: Findings report rewritten: SVD section replaced, synthesis restructured into 3 tiers, extremity LLM bias qualified - U4: Axis labels and sign convention added to svd_stability_report.md - Added centrist_support_mp column (MP-weighted, correlates 0.998 with party-level)	1 month ago
Sven Geboers	76b499cdc0	feat(analysis): Overton window breakpoint analysis with opposition control and SVD drift ... Quantify 2024 breakpoint in centrist support (d=+0.68 overall, d=+0.85 opposition-only), domain decomposition, extremity-stratified pass rates, and manual LLM audit (75% agreement). SVD center drift aborted due to axis instability (9/10 consecutive window pairs fail stability threshold).	1 month ago
Sven Geboers	375955dbc4	cleanup: merge session ledgers into docs/solutions and delete artifacts ... - Remove stale thoughts/ledgers/ and thoughts/shared/ artifacts - Fix .gitignore duplicate .worktrees entry - Move pyright to [dependency-groups] dev - Replace hardcoded blog correlation with reproducible metric reference - Add docs: verify-session-artifacts, fusion-vector-dimensions, working-tree-hygiene - Update blog-numbers-from-pipeline-outputs with correlation example	2 months ago
Sven Geboers	67eda93cb1	docs: add overtone shift analysis and insights ... - Add deep dive analysis on SVD axis overtone shift (docs/research/) - Update brainstorm with results documenting key finding: stability and overtone shift are independent phenomena - Add learning doc about axis stability vs semantic drift independence - Update drift report with detailed findings	3 months ago
Sven Geboers	dafdfd5370	feat: add motion semantic drift analysis script ... - Implement SVD axis stability using Lasso regression on fused embeddings - Add overtone shift analysis to detect semantic content changes - Implement semantic drift tracking for motion content over time - Add party voting analysis with cross-ideological voting patterns - Generate markdown report with visualizations - Add comprehensive test suite with 12 passing tests See reports/drift/report.md for analysis results.	3 months ago
Sven Geboers	50fafeecf3	feat: add motion semantic drift analysis script ... - Add scripts/motion_drift.py: analyzes SVD axis stability, semantic drift, and cross-ideological voting patterns across annual windows - Add analysis/motion_drift.py: core analysis functions with Procrustes alignment fallback using party-based sign consistency - Add matplotlib dependency for static chart generation - Add tests/test_motion_drift.py: 12 tests covering all analysis functions - Report output: markdown with embedded PNG charts Key findings from real data: - No axes are fully stable (>0.7) across 2019-2026 - All axes show moderate consistency (0.40-0.47) — stable within periods but flip between cabinet periods (2019/2022/2026 vs 2023/2024/2025) - Party voting analysis detects cross-ideological voting patterns	3 months ago
