Robot connects to Wi-Fi, estimates the child's position via RSSI trilateration against fixed anchor APs, and pushes it to Firebase Realtime Database. The Expo/React Native app subscribes live and shows position, online status, battery, and safe-zone alerts. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Flip CALIBRATION_MODE to 1 and reflash to get a serial-printed, strongest-first list of nearby APs (SSID/BSSID/RSSI) instead of running trilateration — makes filling in include/anchors.h a matter of reading values off the serial monitor rather than doing it blind.

Create the ducklan Firebase project, its Realtime Database instance, and a pinned Anonymous Auth identity for the robot. Rules now require auth for reads and restrict writes to that one pinned identity, instead of the fully-open rules a "test mode" database would otherwise have. Firmware exchanges a refresh token for short-lived ID tokens before each write; the app signs in anonymously to satisfy the read rule. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Renamed the mascot from "Ducky" to "DuckLAN" throughout and added a DuckLAN wordmark to the Home screen. Lives in ducklan-app/ as a separate Expo Router app so it doesn't touch the existing Firebase/robot-location dashboard in app/.

…tethered Adds an optional Firebase push (main/secrets.h, gitignored) to the WiFi CSI firmware so it reports status to the phone app over WiFi instead of needing a USB cable to a laptop. Without secrets.h the firmware behaves exactly as before (CSI onboarding/following + the USB serial dashboard). App side: new robots/<deviceId>/status Firebase path, useRobotStatus hook, and a CsiStatusCard on the dashboard showing online state, imprint progress, detection count, and fall alerts (no x/y position — a single ESP32 doing CSI sensing can't determine that, so this doesn't fake one).
# Conflicts: # app/src/screens/DashboardScreen.tsx
… secrets template Rotated to a new anonymous Firebase identity for the robot (old one had no recoverable refresh token) and pinned database.rules.json write access to it; deployed live. Also corrected FIREBASE_HOST in secrets.h.example — it was guessed as a regional europe-west1 URL but the actual instance resolves at the legacy ducklan-default-rtdb.firebaseio.com host.
