This track addresses the fragmented implementation of Session Context Snapshots and Discussion Takes & Timeline Branching tracks (2026-03-11) which were marked complete but the UI panel layout was not properly reorganized. New track structure: - Phase 1: Remove ui_summary_only, rename Context Hub to Project Settings - Phase 2: Merge Session Hub into Discussion Hub (4 tabs) - Phase 3: Context Composition tab (per-discussion file filter) - Phase 4: DAW-style Takes timeline integration - Phase 5: Final integration and cleanup Also archives the two botched tracks and updates tracks.md.
