+# FleetTracker360 — CHANGELOG
+
+## 2026-07-16 — Branding & GPS Accuracy
+
+### Branding
+- Replaced Traccar logo SVG with FleetTracker360 (GPS dot + signal waves + gradient text)
+- Created custom branded login page at `/login.html` — dark navy theme, animated grid background
+- HTTPS proxy: Caddy on Core (gps.fleettracker360.com) → Traccar on app2 (152.53.39.202:8082)
+- DNS: gps.fleettracker360.com moved from app2 direct to Core proxy (Cloudflare proxied)
+
+### GPS Accuracy
+- Server-side filtering enabled in Traccar config:
+  - `filter.enable=true` (Kalman smoothing)
+  - `filter.accuracy=30` (reject cell tower triangulation >30m)
+  - `filter.distance=5` (ignore micro-jitter <5m)
+  - `geolocation.enable=true` (road snapping via Nominatim)
+- Computed attributes added to database:
+  - `motion`: auto-detect transport mode (walking/cycling/driving/flying)
+  - `gpsQuality`: tag fix accuracy (excellent/good/fair/poor)
+
+### Still Pending
+- Computed attribute device linking in UI
+- Full community dashboard integration
