Major corrections:
- Fix PC2 factual error: CU/CDA/SGP/D66 are strongly negative (-13 to -58), not near zero
- Correct methodology: party scores use single-window SVD, not Procrustes pipeline
- Correct centering: global (after stacking), not per-window
- Fix Groep Markuszower misclassification on PC4 (positive, not negative pool)
- Fix D66/PC4-PC5 cross-reference error
- Fix PC8/DENK interpretation (negative = voting against, not absence of focus)
Additions:
- Party sizes (N=) for all 17 parties across all axes
- Party size reliability table (D66=26 to Volt=1)
- All 5 flip values documented (PC3,4,7,9,10), not just PC3
- Vector-space mismatch table (single-window scores vs Procrustes EVR)
- Cautionary '(indicatief label)' on PC7-PC10
- New follow-up steps: bootstrap CIs, dimensionality testing, varimax, external validation
- Softened causal claims (kabinetscrisis correlation, PVV motivations)
- Less normatively loaded PC2 label
