💡 What:
Replaced .onTapGesture on generic interactive HStack list rows with standard Button(action: {}) wrappers. Applied .buttonStyle(.plain) to prevent default styling, and carefully preserved the .contentShape(Rectangle()) modifier.

🎯 Why:
Using .onTapGesture on list items prevents them from being triggered by keyboard navigation (Space/Return) and hides their interactive nature from VoiceOver and other screen readers.

📸 Before/After:
Visually identical.

Accessibility:
This enhancement directly improves the app for keyboard-only and screen reader users by providing native focus handling, semantic button traits, and functional keyboard activation for interactive list elements in the Recommendations Sheet and Chord/Sequence views.

Summary by CodeRabbit

  • Accessibility
    • Improved keyboard navigation and screen reader support for interactive list rows.
    • Chord and sequence rows now use accessible button controls while preserving their existing appearance and editing behavior.
    • Recommendation rows can be selected by tapping anywhere on the row, with clearer interactive semantics for assistive technologies.
    • Preserved existing actions, labels, tooltips, and selection behavior across these rows.

- Wrapped interactive `HStack` rows in `Button` with `.buttonStyle(.plain)` in `RecommendationsSheet.swift` and `ChordSequenceListViews.swift`.
- Ensures rows can be navigated and activated via keyboard (Space/Return keys).
- Preserved `.contentShape(Rectangle())` to maintain full clickable area.

📝 Walkthrough

Walkthrough

SwiftUI chord, sequence, and recommendation rows now use plain-styled Button controls instead of row-level .onTapGesture handlers. Existing actions and content logic remain unchanged. DEBUG-only layer diagnostic prints were removed. The accessibility journal documents the button pattern.

Changes

Accessible row controls

Layer / File(s) Summary
Editable chord and sequence rows
.Jules/palette.md, XboxControllerMapper/XboxControllerMapper/Views/MainWindow/ChordSequenceListViews.swift
ChordRow and SequenceRow now invoke onEdit through plain-styled buttons. The journal records the related accessibility pattern.
Recommendation row selection
XboxControllerMapper/XboxControllerMapper/Views/MainWindow/RecommendationsSheet.swift
The full recommendation row now toggles selection through one plain-styled button.

Mapping diagnostic cleanup

Layer / File(s) Summary
Layer activation diagnostics
XboxControllerMapper/XboxControllerMapper/Services/Mapping/MappingEngine.swift
DEBUG-only prints for layer activation, toggling, release deactivation, and chord-based changes were removed. Input logging and layer behavior remain.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to a6d4e

Recommendation selection is now exposed as a button, but assistive technologies may not receive clear selected-state and action information. This is a bounded accessibility risk that should be addressed before or shortly after merge.

Expose the recommendation selection state.

The Button toggles selectedIds, but its accessibility tree does not expose isSelected. Add an accessibility value and hint so assistive technologies announce the current state and action.

- Wrapped interactive `HStack` rows in `Button` with `.buttonStyle(.plain)` in `RecommendationsSheet.swift` and `ChordSequenceListViews.swift`.
- Ensures rows can be navigated and activated via keyboard (Space/Return keys).
- Preserved `.contentShape(Rectangle())` to maintain full clickable area.
- Fixed a CI pipeline test deadlock caused by excessive synchronous `print` logging in the hot-path `MappingEngine.swift` (by reverting strictly to `inputLogService`).
