VoiceAssist Frontend Completion Plan

Executive Summary

This document outlines the comprehensive implementation plan for completing the VoiceAssist frontend MVP. Based on thorough codebase analysis, the frontend is approximately 65% complete with solid foundations in place.

Current State Assessment:

Estimated Total Effort: 180-240 hours (9-12 weeks at 20 hrs/week)

Phase 8: Polish & Production Readiness

8.1 Fix Test Failures & CI Issues

Estimate: 4-6 hours | Priority: CRITICAL | Risk: Low

Current State

• Vitest 1.6.1 configured with memory optimization (pool: 'forks', maxConcurrency: 3)
• ESM import issues already addressed via inline: ['refractor', 'remark-gfm', ...]
• 578 tests passing, 9 skipped
• Bandit configured in .bandit, runs in CI
• Trivy container scanning configured in trivy.yaml

Tasks

Implementation

# Add to .github/workflows/ci.yml
frontend-lint:
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@v4
    - uses: pnpm/action-setup@v2
    - run: pnpm install --frozen-lockfile
    - run: pnpm lint
    - run: pnpm tsc --noEmit

8.2 Complete Offline Voice Capture

Estimate: 8-12 hours | Priority: HIGH | Risk: Medium

Current State

• useOfflineVoiceCapture.ts (479 lines) - FULLY IMPLEMENTED
• IndexedDB storage with proper schema (voiceassist-offline DB)

• Integration with VoiceModePanel.tsx exists

Gap Analysis

• No storage quota management
• No audio compression before storage
• UI indicator exists but may need polish
• Background sync API not used

Tasks

Implementation Notes

// Storage quota management
async function checkStorageQuota() {
  if (navigator.storage?.estimate) {
    const { usage, quota } = await navigator.storage.estimate();
    const percentUsed = (usage! / quota!) * 100;
