Phase 42 Plan 04: Voice Offline Badge and useSystemProviders Hook

useSystemProviders hook wires /api/system/providers to ChatInput offline badge, surfacing local Whisper availability via WifiOff icon when voice mode is active

Performance

• Duration: 2 min
• Started: 2026-04-04T22:12:11Z
• Completed: 2026-04-04T22:14:00Z
• Tasks: 2
• Files modified: 2 (1 created, 1 modified)

Accomplishments

• Created useSystemProviders hook that fetches /api/system/providers once on mount, extracts voiceCapability.whisperAvailable, and returns null providers on error for graceful degradation
• Added WifiOff icon offline badge to ChatInput — renders only when enableVoiceInput=true AND providers.whisperAvailable=true
• Verified VoiceMicButton and VoiceModeToggle already rendering correctly from prior phase work (no changes needed)

Task Commits

Each task was committed atomically:

1. Task 1: Create useSystemProviders hook - 768f62fa (feat)
2. Task 2: Add offline badge to ChatInput - 69ae0a00 (feat)

Files Created/Modified

• ui/src/hooks/useSystemProviders.ts - One-shot fetch hook for system providers; exports SystemProviders interface and useSystemProviders function
• ui/src/components/ChatInput.tsx - Added WifiOff import, useSystemProviders call, and offline badge JSX next to VoiceMicButton

Decisions Made

• Used plain useState+useEffect pattern (not React Query / useHardwareInfo) as the plan specified — the hook is intentionally lightweight for a one-time capability probe
• Mapped voiceCapability sub-object from HardwareInfo since the /api/system/providers endpoint returns the full hardware info shape; whisperAvailable lives at data.voiceCapability.whisperAvailable

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Offline badge available in ChatInput; voice UI feature surface is now complete
• Plan 06 (UI wiring) can wire enableVoiceInput prop from user settings/mode state
• Voice mode toggle and mic button confirmed rendering correctly when enableVoiceInput=true
