-# Bug 47: Fix Collect Coverage Button Error
-
-## Description
-
-Pressing "Collect Coverage" in the workflow gates UI produces a large error. The feature expects a vitest `coverage-summary.json` but the project doesn't have coverage tooling configured.
-
-## Expected Behavior
-
-Either the coverage collection works end-to-end, or the button is hidden/disabled when coverage tooling is not available.
-
-## Steps to Reproduce
-
-1. Start the server
-2. Open the frontend
-3. Navigate to workflow gates
-4. Press "Collect Coverage"
-5. Large error is displayed
-
-## Acceptance Criteria
-
-- [ ] "Collect Coverage" either works or fails gracefully with a clear message
-- [ ] No giant error dump shown to the user

+# Story 48: Two-Column Layout — Chat Left, Panels Right
+
+## User Story
+
+As a user, I want the chat and panels to sit side by side so that the panels don't crowd out the chat history.
+
+## Acceptance Criteria
+
+- [ ] Chat header spans the full width across the top
+- [ ] Below the header, the layout splits into two columns:
+  - **Left column**: Chat messages (scrollable) with chat input pinned at the bottom
+  - **Right column**: All panels (Agent, Review, Gate, Todo, Upcoming) stacked vertically, independently scrollable
+- [ ] The left column takes roughly 60% width, right column 40%
+- [ ] On narrow screens (below ~900px), the layout falls back to a single column with panels stacking below the chat
+- [ ] Chat input is no longer affected by panel height — it stays pinned at the bottom of the left column regardless of how many panels are expanded
+
+## Out of Scope
+
+- Resizable/draggable column divider
+- Collapsible right panel sidebar toggle
+- Removing or consolidating panels
