| ✅ | Item | |----|------| | Public‑access check | Only files where anyoneWithLink permission exists are shown. | | Copyright disclaimer | Rendered whenever the file’s metadata does not indicate a public‑domain or Creative‑Commons license. | | Terms of Service | Ensure the widget respects Google Drive API quotas (max 10 requests/second per IP). | | Privacy | No user‑identifying data is stored; only aggregate view counts (IP‑anonymized). | | Accessibility | PDF viewer includes ARIA labels; all buttons are keyboard‑focusable. | 6. Project Timeline (Typical Agile Sprint) | Sprint | Deliverable | |--------|-------------| | Sprint 1 (1 wk) | API proxy scaffolding, service‑account integration, basic /drive-search endpoint. | | Sprint 2 (1 wk) | Front‑end component skeleton, loading/error UI, unit tests for proxy. | | Sprint 3 (1 wk) | PDF preview modal + PDF.js integration, responsive styling. | | Sprint 4 (1 wk) | Legal disclaimer logic, admin toggle (allow/block), logging middleware. | | Sprint 5 (1 wk) | QA, cross‑browser testing, performance profiling, documentation. | | Sprint 6 (0.5 wk) | Production deployment, monitoring dashboard (API‑call health). | 7. Monitoring & Maintenance | Metric | Tool | Alert Threshold | |--------|------|-----------------| | Drive API latency | CloudWatch / Grafana | > 800 ms | | 4xx/5xx responses from proxy | Sentry | > 5 % error rate | | PDF viewer crash rate | Sentry (frontend) | > 2 % sessions | | Download count per day | Custom DB log | Unexpected spikes → review copyright compliance | 8. Optional Enhancements | Feature | Value | Rough Effort | |---------|-------|--------------| | Search auto‑complete (suggest other titles) | Keeps users on site longer | +1 day | | Multiple source fallback (OneDrive, Dropbox) | Improves availability | +2 days | | User‑submitted links (moderated) | Community‑driven content | +3 days (moderation UI) | | Full‑screen PDF viewer | Better reading experience on tablets | +1 day | | Analytics dashboard for admins | Insight into popularity | +2 days | 9.
