+# CLAUDE.md — RALPH Android Frontend
+
+## Stack
+
+Language:  Kotlin
+UI:        Jetpack Compose
+DB:        Room (SQLite)
+Worker:    WorkManager
+Maps:      MapLibre + OpenStreetMap
+HTTP:      Retrofit oder Ktor Client (TBD)
+Auth:      TBD (API-Key vs JWT für Upload)
+
+---
+
+## Kern-Features (Android)
+
+1. Background GPS-Tracking (COARSE/FINE + Background permission)
+2. Offline Queue (Room) + WorkManager Upload (Idempotenz via event_id)
+3. Manuelle Punkte hinzufügen (lat/lon/timestamp/notiz + Validierung)
+4. Kartenansicht (MapLibre, Tile-Quelle konfigurierbar)
+5. Datei-Export (SAF ACTION_CREATE_DOCUMENT)
+
+---
+
+## Architektur-Prinzipien
+
+- Offline-First: Jeder Punkt wird zuerst lokal in Room gespeichert
+- Upload via WorkManager mit Constraint: Network connected + Retry/Backoff
+- Idempotenz: Jeder Punkt erhält eine client-seitige event_id (UUID)
+- source-Feld: "gps" | "manual" unterscheidet Punkt-Typ
+- Validierung manueller Punkte: as the user types im ViewModel
+
+
+---
+
+## Offene Entscheidungen (TBD)
+
+- HTTP Client: Retrofit vs Ktor
+- timestamp Format: epochMillis vs RFC3339
+- Android Upload Auth: X-API-Key vs JWT
+- minSdk festlegen
+
+---
+
+## Nächste Tasks (Reihenfolge)
+
+- [ ] T001  Compose-Projekt anlegen (Kotlin, minSdk festlegen)
+- [ ] T001a Kotlin-Standards festlegen (Coroutines, KTX, Code Style)
+- [ ] T004  Permissions Manifest + Runtime-Flow (COARSE/FINE + Background)
+- [ ] T006  Background-Tracking Architektur (Foreground Service)
+- [ ] T033  Room-Setup (Entities/DAOs/Migrations)
+- [ ] T008  Upload-Queue (pending/sent/failed, retryCount)
+- [ ] T012  Upload-Worker (WorkManager, Retry/Backoff)
+- [ ] T080  UI: Manuellen Punkt hinzufügen
+- [ ] T081  Eingabevalidierung Compose (as the user types)
+- [ ] T018  Export via SAF
+
+---
+
+## Antwort-Stil
+
+- Kotlin-Code immer mit Coroutines/Flow
+- Compose-Code: State Hoisting, ViewModel pattern
+- Kein direkter DB/Network-Zugriff in Composables
+- Tests: JVM Unit Tests für Domain/Queue; Instrumentation für Room/Worker

+#
+#   Important for running:

+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other POSIX-compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for distributing:
