SVD axes capture agreement structure — centrists 'moving left' means
voting patterns diverged from right-wing, not that parties changed
ideology. 'Acceptance without conversion' is a behavioral claim.
Documented as best-practice learning.
Captures the 7-step methodology developed through multiple analysis
iterations: strict centrist definition, Procrustes-aligned SVD with
anchor-party sign validation, centrist support fraction over pass rate,
acceptance-without-conversion test, opposition-only filter as coalition
control, extremity-stratified tolerance analysis, and LLM score auditing.

confirming lint rule coverage before trusting it for enforcement.
Documents the P2-002 incident where ruff BLE only catches bare
not .

- Add detailed implementation plans for P1-001 through P4-005
- Add research artifacts and solution docs from ledger merge
- Add test for SVD component 1 compass alignment
- 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
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.

- refactoring-streamlit-data-loading.md: update test count
164/164 → 173/173 (7 new axis validation tests added)
- svd-component-labels-mismatch.md: SVD_THEMES moved from
explorer.py:434-611 → analysis/config.py:67+ per the
refactoring that extracted constants to analysis/config.py
- Add AGENTS.md with documented solutions reference
- Include SVD label convention (right-wing parties on right side)
- Document SVD insight: labels reflect voting patterns, not semantics
- Fix SQL verification example to use Python approach
