+# Restore Mobile Terminal Scrolling
+
+## Summary
+
+The recent terminal scrollback optimization disabled scrollback for every viewport. Mobile terminal swipe handling still scrolls xterm's normal buffer programmatically, so swipes in normal-buffer tools no longer have retained output to move through.
+
+## Root Cause
+
+`468f342` changed the terminal configuration to `scrollback: 0` globally to prevent stale repaint frames and wheel scrolling on desktop. The mobile touch handler calls `term.scrollLines()` when the normal buffer is active. With zero scrollback, that call has no scrollable history and becomes a no-op.
+
+## Scope
+
+- `apps/web/src/components/features/terminal/terminal.tsx`
+- Focused terminal configuration test
+
+## Fix
+
+Retain a bounded xterm scrollback buffer on mobile only (`10000` lines), while leaving desktop at zero scrollback and with wheel sensitivity disabled. Mobile's existing custom touch handler remains responsible for moving through normal-buffer history; alternate-screen swipes continue to send SGR wheel events to the active TUI.
+
+## Acceptance Criteria
+
+- [ ] A mobile terminal with normal-buffer output exceeding one screen scrolls via a vertical swipe.
+- [ ] Alternate-screen terminal scrolling continues to use the existing SGR wheel-event path.
+- [ ] Desktop keeps zero xterm scrollback and disabled native wheel scrolling, so stale repaint frames do not return.
+- [ ] Focused unit test and frontend quality gates pass.

+# Restore Mobile Terminal Scrolling — Tasks
+
+- [x] Add a mobile-specific terminal scrollback limit while preserving zero scrollback on desktop.
+- [x] Reinitialize the terminal when the responsive mobile classification changes so its scrollback and touch handler match the active viewport.
+- [x] Add focused tests for the responsive scrollback configuration.
+- [x] Run the full frontend test suite (89 tests passed after repairing the `ProjectsPage` test setup).
+- [x] Run frontend typecheck, lint, focused tests, and production build.
+- [ ] Perform mobile normal-buffer and alternate-screen manual QA.
+- [ ] Update project maps for changed source files (the map patch tool currently fails with an unsupported `temperature` parameter).
