-- BUG-10: GPS-only false trips gated on OBD presence
+- BUG-09: Geocode pre-caching for fast scrubber (pre-existing)
+- BUG-10: GPS-only false trips gated on OBD presence (pre-existing). Side fix: `refresh_trips()` preserves existing trips when `was_car_ever_connected()` is False (was deleting all trips on restart).
 
-**Still open:** BUG-01 (hotspot/phone — netwatch fix deployed, needs in-car test), BUG-02 (hardware power), BUG-06 (timezone), BUG-07 (intermittent replay).
+**Deployed, awaiting in-car test:**
+- BUG-01: Dual-radio setup — wlan0 is permanent AP at 10.42.0.1, wlan1 handles internet uplink only. `yaris_uplink.py` no longer touches the AP. In-car access card on Settings page shows hotspot URL + cell-data warning. Netwatch fixed to not tear down AP when clients connected (backup, not needed with dual-radio).
+
+**Still open:** BUG-06 (timezone shift), BUG-07 (intermittent replay).
+BUG-02 is hardware (Pi micro-USB port damage) — owner's responsibility.
 
 **Acceptance:** every `BUGS.md` entry in scope is fixed, regression-tested, deployed, and marked resolved.
