+## Up Next
+
+### Phase 4 — Accountability
+
+- [ ] **Votes & Committees** — fetch roll-call votes from Congress.gov into a `bill_votes` table. UI: vote results filterable by followed members and topics; timeline entries for committee actions.
+- [ ] **Member Effectiveness Score** — nightly Celery task; transparent formula: sponsored bills, bills advanced through stages, co-sponsorships, committee participation, bills enacted. Stored in `member_scores`. Displayed on member profile with formula explanation.
+- [ ] **Representation Alignment View** — for each followed member, show how their votes and actions align with the user's followed topics. Neutral presentation — no scorecard framing.
+
+### Phase 5 — Search & Polish
+
+- [ ] **Search Improvements** — filters on global search (bill type, status, chamber, date range); search within a member's sponsored bills; topic-scoped search.
+- [ ] **Desktop View** — wider multi-column layout for large screens: sticky sidebar, expanded grid, richer bill detail.
+- [ ] **first_name / last_name Backfill** — Celery task to populate empty first/last from stored "Last, First" `name` field via split (affects ~10% of member records).
+
+### Backlog
+
+- [ ] **Notification Channels v2** — email (SMTP), Discord webhook, Telegram bot.
+- [ ] **Cross-Bill Referencing** — extract referenced bill IDs from LLM briefs; `bill_references` table; hover preview popover in BriefPanel for referenced legislation.
+- [ ] **Source Viewer Option B** — in-app bill text viewer with cited passage highlighted and scroll-to-anchor. Deferred pending UX review of the current GovInfo-link approach.
+- [ ] **Raw Diff Panel** — `difflib` diff between stored document versions, shown as collapsible "Raw Changes" below the amendment brief. Zero API calls.
+- [ ] **Shareable Collection Subscriptions** — "Follow this collection" so other users can subscribe to a public collection and get its bills added to their feed.
