Member Effectiveness Score
- New BillCosponsor table (migration 0018) with per-bill co-sponsor
party data required for the bipartisan multiplier
- bill_category column on Bill (substantive | commemorative | administrative)
set by a cheap one-shot LLM call after each brief is generated
- effectiveness_score / percentile / tier columns on Member
- New bill_classifier.py worker with 5 tasks:
classify_bill_category — triggered from llm_processor after brief
fetch_bill_cosponsors — triggered from congress_poller on new bill
calculate_effectiveness_scores — nightly at 5 AM UTC
backfill_bill_categories / backfill_all_bill_cosponsors — one-time
- Scoring: distance-traveled pts × bipartisan (1.5×) × substance (0.1×
for commemorative) × leadership (1.2× for committee chairs)
- Percentile normalised within (seniority tier × party) buckets
- Effectiveness card on member detail page with colour-coded bar
- Admin panel: 3 new backfill/calculate controls in Maintenance section
Representation Alignment View
- New GET /api/alignment endpoint: cross-references user's stanced bill
follows (pocket_veto/pocket_boost) with followed members' vote positions
- Efficient bulk queries — no N+1 loops
- New /alignment page with ranked member list and alignment bars
- Alignment added to sidebar nav (auth-required)
