Release v0.1.3: OFSI List Change Feed, SMS Alerts & Notification Settings

12 February 2026

What changed

• OFSI list change feed — The system now automatically detects additions, removals, and modifications between OFSI list versions. A new /dashboard/sanctions/changes page shows changes grouped by version date with filtering, pagination, and portfolio impact indicators. A dashboard widget surfaces the latest 5 changes.
• SMS alerts — New Twilio-based SMS channel. Users add a phone number, verify it via a 6-digit OTP code, then receive SMS notifications when OFSI list changes affect their portfolio. Phone numbers are masked in all logs.
• Notification settings — New settings section with toggles for email alerts (match notifications, list changes, daily digest), SMS alerts (per alert type), and periodic all-clear confirmations (daily/weekly/monthly).
• Accessibility — WCAG 2.1 AA compliance: proper ARIA labels, role="switch" on toggles, role="feed" on the changes list, keyboard navigation with focus rings, and semantic HTML throughout.
• GDPR — Notification preferences can be fully deleted via a new DELETE endpoint.

Why it matters

Users no longer need to manually check whether the OFSI list has changed. The change feed shows exactly what moved and who in your portfolio might be affected. SMS alerts mean you find out immediately, even if you're away from your desk.

Technical notes

• 3 new database tables: ofsi_list_changes, notification_preferences, sms_log
• 5 new API endpoints (GET/PUT/DELETE notification preferences, POST SMS verify, GET sanctions changes)
• New env vars: TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, TWILIO_PHONE_NUMBER (all optional — SMS degrades gracefully without them)
