The Files filter row now uses the same horizontal edge fade as the terminal and task composer pill bars. Filters scroll inside a bounded viewport, while the sort control remains fixed at the trailing edge and the fade tracks the live content offset.

Validation:

The iOS controller fleet has an iOS-labeled worker, but its provisioned recipe is unsigned simulator output only. Hosted iOS checks are required for package compilation and tests.


Summary by cubic

The Files filter chips now scroll with the same horizontal edge fade used by the terminal and task composer pill bars, with the sort control fixed at the trailing edge and the prior row height preserved.

  • Generalized the task-composer pill bar into a reusable HorizontalEdgeFadePillBar with configurable content insets and accessibility identifier.
  • The task composer keeps its existing behavior and MobileTaskComposerPillScroller identifier.
  • The Files filter row keeps its prior height and gains the TerminalArtifactGalleryFilterScroller identifier.

Written for commit 2de9f29. Summary will update on new commits.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep the Files filter row at 44 points.

.frame(height: 34) is followed by .padding(.vertical, 10), so galleryControls occupies 54 points. This adds 10 points to the row and pushes the divider and file content down. Adjust the inner height or padding so the combined layout height is 44 points.

Proposed fix
-        .frame(height: 34)
+        .frame(height: 24) // 24 + 10 + 10 = 44
