+-- v1.4.27 B3 — Persist the ASN + carrier on login audit rows.
+--
+-- The bundled MaxMind GeoLite2-ASN MMDB resolves an autonomous-system
+-- number and the organisation string ("Deutsche Telekom AG") at
+-- audit-creation time. Both columns are nullable so the schema stays
+-- valid for older rows, for private/loopback IPs that skip the
+-- lookup entirely, and for offline-miss rows that the resolver could
+-- not match.
+--
+--   asn      — INTEGER, the autonomous-system number from the MMDB.
+--   carrier  — TEXT, the autonomous-system organisation string.
+--
+-- The `IF NOT EXISTS` guards make the migration idempotent — the
+-- demo server may already carry hand-edited columns from a prior
+-- partial run, and the same migration must apply cleanly to a fresh
+-- database. Same posture as 0058_user_research_mode.
