-- Photo upload (attachments)
-- Magic-link sign-in and password reset by email

-- Status workflow: Reported → Triage → Investigation → Corrective actions → Verification → Closed, with role-based transitions
-- "My actions" list and overdue tracking
-- Email notifications: assignment, due dates, high-severity alerts
-- CSV and PDF export
-- Dashboard metrics computed from real data
+- [x] Web app connected to the API: sign-in, first-run setup, every page on live data (demo data removed from the frontend)
+- [x] Photo and PDF upload, checked by file content (not name), size-limited, served with a sandboxing security policy
+- [x] Magic-link sign-in, password reset by email, email invitations for new users (admins can also set passwords when there's no email)
+- [x] Incident detail page: details editing, activity log (comments + audit trail), investigation with 5 Whys and fishbone (6M) views, corrective actions (CAPA)
+- [x] Status workflow Reported → Triage → Investigation → Corrective actions → Verification → Closed, with role rules and guards (e.g. high severity can't skip investigation; closing needs every action verified), shared between API and UI
+- [x] "My actions" and "All actions" lists with overdue tracking; assignees can update progress on their own actions
+- [x] Email notifications: high/critical alerts to safety managers, action assignment, daily due/overdue digest
+- [x] CSV export of the filtered register (protected against spreadsheet formula injection); print-friendly incident page for PDF via the browser
+- [x] Overview dashboard and Analytics computed from real data; Locations and Settings (people, roles, passwords) pages

+- [ ] **Server-side PDF (later).** Decided 2026-10-06 to keep browser-generated PDFs for now: the "Print / PDF" button and print stylesheet are simpler and add no dependencies. Revisit if PDFs need to be produced automatically, e.g. attached to emails or archived on close.
+- [ ] **Email delivery (later).** Decided 2026-10-06 that the current behavior is fine for now: without `SMTP_URL`, emails print to the server log in development and are dropped (with a startup warning) in production. Later: configure SMTP for real deployments, add a "send test email" button for admins, and consider showing admins a warning in the app when email isn't set up.
+- [ ] **Notification preferences.** Everyone gets every email that applies to them. Add per-user opt-outs, and an alert-recipients setting per site.
