CRIT-1: Stylistic extremity direction reversed — both dimensions declined
(stijl 1.875→1.744, not increased +0.097). Holistic moderation, not divergence.
CRIT-2: Masking rate corrected from 36.1% to 9.7% (S≤2, M≥4 on full dataset).
Original 36.8% was from 117-motion manual audit, not extrapolatable.
CRIT-3: Material impact values harmonized to motion-level means (2.79→2.45).
Old values (2.78→2.43) used undisclosed mean-of-yearly-means aggregation.
HIGH-1: Migration domain provenance caveat — category column is NULL,
analysis relies on title keyword matching (approximate boundaries).
HIGH-2: 2026-Q2 bounce caveat — n=44, bimodal distribution, sensitive to
composition (many consensus defense motions among CS=1.0 items).
HIGH-3: Non-right-wing control group corrected — CS rose 58%→62% (+3.5pp),
not 'flat at 49%'. Surge was disproportionate for right-wing content.
Also: fixed 6-party centrist definition (line 30) to 4-party,
removed 'did not shift rightward' phrasing, added Phase 4 synthesis
reminder to build_all_reports.py.
Key finding from 2026 data:
- 2026-Q2 CS bounced back to 0.523 (from 0.334 in Q1)
- Migration CS (0.395) now EXCEEDS non-migration (0.368) for first time
- Multiple 2026-Q2 migration motions got unanimous centrist support (CS=1.00)
Updated verdict across synthesis, QMD, and HTML:
- Non-migration acceptance was a temporary electoral shock response
- Migration acceptance is durable and growing as debate intensifies
- The Overton shift is domain-specific, not uniformly temporary
Also fixed hashline formatting corruption in synthesis file.
- Verdict now says 'window widened' (not 'did not shift') — centrist
support surged for right-wing motions while staying flat for left-wing
- Migration reframed from 'one exception' to 'gateway domain' — where
acceptance expanded most genuinely and right-wing parties learned
frames they applied elsewhere
- Explorer Overton tab: added migration gateway section with pre/post
metrics, full motion text (no truncation), 100-motion browser
- Explorer Kompas tab: updated Overton context to lead with the shift
- Explorer Trajectories tab: Dutch-language Overton annotation
- Synthesis, QMD, HTML report, STATUS.md all updated consistently
