Populated the right_wing_motions.category column (previously 100% NULL across
3,030 motions) via parallel subagent classification — 80 agents derived a
10-category taxonomy and classified all motions in minutes.
Adds to the Overton QMD report:
- Plotly dropdown filter on Chart 1 to toggle between policy categories
- Chart 7: category delta bar chart (pre/post centrist support per domain)
- Chart 8: quarterly domain trajectories for the 5 largest categories
- Domain Decomposition narrative section
Also fixes a Streamlit tab crash (m.text -> m.body_text) and adds TDD tests.
U1: JA21 drives moderation effect (+0.203 CS shift, only party with volume+support gains)
U2: Coalition coding split at July 2024 — opposition effect confirmed (d=0.85 vs 0.87)
U3: Voting margin (ρ=0.812 with centrist support) is far superior to pass rate
U4: SVD trajectory confirms spatial divergence — centrists moved left (Δx=-0.30), right stationary
U5: Mechanism classification Cohen's κ=0.41 (moderate) — taxonomy needs revision
U6: Predictive model AUC-ROC=0.81 — submitter party and category are strongest predictors
