Material impact declined post-2024 (2.78→2.43, M>=4 share 23.7%→11.3%).
Right-wing strategic moderation: more motions, milder content, better
framing. The Overton window did not expand — right-wing proposals
shifted into the existing window. 'Acceptance through moderation'
replaces 'acceptance without conversion.'
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.
- Classified 24 post-2024 right-wing motions with CS>=0.5
- Dominant mechanisms: consensus framing (33%), institutional (21%), welfare (17%)
- Only 1 targeted restriction, zero system dismantling
- Right-wing gains centrist support through repackaging, not conversion
- Confirms acceptance-without-conversion dynamic at the mechanism level
- Pearson r=0.45 between stylistic and material impact (separable)
- Material impact averages 0.85 points above stylistic
- 36.8% of motions mask high-impact policy behind restrained language
- Original single-score conflates language vs substance
- Mark U4 mechanism analysis as in progress
- Project-local skill .opencode/skills/score-extremity/ for subagent dispatch
- Orchestrator extremity_rescore_2d.py with load_skill/sample/format/validate/store
- 16 TDD tests covering all orchestrator functions
- 117 motions scored by deepseek v4 flash subagents (12 parallel batches)
- Pearson r=0.45 between stylistic and material dimensions — separable
- Key finding: 36.8% of motions use restrained language for consequential policies
- 2d_extremity_correlation_report.md documents distribution, divergence patterns,
and implications for the Overton acceptance-without-conversion narrative
- Reclassified centrist to {D66, CDA, CU, NSC} — removing VVD/BBB
which are center-right coalition partners
- Added centrist_support_strict (0.251→0.507, d=+0.65), center_right_support,
and left_support_mp columns via migration script
- Figure 1 now shows center-right (VVD/BBB) support as orange dashed line
- New Figure 3: bar chart of left-party support for right-wing motions
(0.268→0.202, left opposition hardened)
- New report Section 6 covering left-wing support trends
- All analysis now uses strict centrist definition throughout
