+# Architecture: Wetter-Klon (Android, ohne Google)
+
+Basis: `recon.md`, `features.csv`. Schwerpunkt: **modernes Design und Homescreen-Widgets**.
+Es gibt keinen Server, keine Accounts und keine Zahlungen. Die App läuft komplett auf dem Gerät und spricht nur öffentliche, schlüsselfreie APIs an.
+
+## Stack
+
+| Schicht | Wahl | warum |
+| --- | --- | --- |
+| Sprache/UI | Kotlin + Jetpack Compose, **Material 3 Expressive** | native Animationen, Shape-Morphing, Dynamic Color: genau der Look des Originals |
+| Hintergründe | Compose Canvas + **AGSL Runtime Shaders** (API 33+), Fallback auf Canvas-Partikel | flüssiger Regen/Schnee/Wolken/Sonne bei 60–120 fps, eigene Grafik statt Google-Assets |
+| Widgets | **Jetpack Glance** (+ RemoteViews nur wo nötig) | Compose-artige Widget-API, responsive Größen, Dynamic Color |
+| Persistenz | Room (SQLite) + DataStore | eine lokale DB, offline-first |
+| Netzwerk | Ktor Client + kotlinx.serialization | leicht, keine Google-Abhängigkeit |
+| Hintergrundjobs | WorkManager | Refresh, Warnungen, Widget-Updates ohne Play Services |
+| Standort | `android.location.LocationManager` (kein Fused Provider) | funktioniert ohne GMS (GrapheneOS, /e/, LineageOS) |
+| Karte | MapLibre Native + OSM-/OpenFreeMap-Tiles, RainViewer-Radarkacheln | Open Source, keine Google Maps |
+| DI | Hilt oder manuell (Koin) | Koin: weniger Magie, reicht für eine App |
+| Build/Verteilung | Gradle KTS, minSdk 29, targetSdk aktuell, F-Droid-tauglich (keine proprietären Libs) | |
+
+## Datenquellen (offiziell, öffentlich)
+
+| Zweck | API | Hinweise |
+| --- | --- | --- |
+| Vorhersage aktuell/stündlich/10 Tage | Open-Meteo `/v1/forecast` (`models=best_match`, für DE `icon_seamless`) | kostenlos nichtkommerziell, CC BY 4.0, Attribution in den Einstellungen |
+| Minutengenauer Niederschlag | Open-Meteo `minutely_15` | Basis für „Regen in 20 Min“ |
+| Luftqualität + Pollen | Open-Meteo Air Quality API | Pollen nur in Europa |
+| Ortssuche | Open-Meteo Geocoding API | Name/PLZ |
+| Reverse Geocoding (GPS → Name) | Nominatim (OSM), max. 1 Req/s, eigener User-Agent | nur beim Standortwechsel |
+| Warnungen DE | DWD Warnungen (`warnings.json`/CAP) über Bright Sky API | |
+| Warnungen EU | MeteoAlarm CAP/Atom Feeds | |
+| Radar | RainViewer Weather Maps API (Vergangenheit + Nowcast) | Attribution Pflicht |
+
+## Schema
+
+Siehe `schema.sql`: 6 Tabellen (`locations`, `card_layout`, `forecast_cache`, `alerts`, `widget_config`, `notification_pref`), die Einstellungen liegen in DataStore.
+Zugriffsregeln: Es gibt keinen Mehrbenutzerbetrieb, Row Level Security entfällt. Die Daten liegen app-privat im Sandbox-Speicher, Backup über Auto Backup ist optional (ausschaltbar).
+Harte Constraints: nur ein `is_current`-Ort (partieller Unique-Index), keine doppelten Orte (gerundete Koordinaten), Warnungen werden über die Provider-ID dedupliziert.
+
+## Interne „API“ (Repositories / Use Cases)
+
+| Aufruf | macht | Input | Output | Flow |
+| --- | --- | --- | --- | --- |
+| `ForecastRepo.observe(locId)` | Flow aus Cache, löst Refresh aus, wenn älter als 30 min | locId | `Forecast` + Status (fresh/stale/offline) | F01 |
+| `ForecastRepo.refresh(locId, force)` | Open-Meteo forecast + air laden, Cache schreiben | locId | Result | F01 |
+| `LocationRepo.updateCurrent()` | GPS → Reverse Geocoding → `is_current`-Zeile | – | Location | F01 |
+| `LocationRepo.search(q)` | Geocoding, entprellt 300 ms | query | List<Place> | F02 |
+| `LocationRepo.add/delete/reorder` | CRUD + Standard-`card_layout` anlegen | Place / id / order | – | F02, F03, F04 |
+| `LayoutRepo.move(locId, card, toPos)` | Kartenreihenfolge pro Stadt | – | – | F07 |
+| `AlertRepo.sync(locId)` | DWD/MeteoAlarm abrufen, abgelaufene löschen | locId | List<Alert> | F08 |
+| `RadarRepo.frames()` | RainViewer-Frame-Liste (−2 h … +30 min) | – | Frames | F05 |
+| `BriefGenerator.build(forecast, alerts)` | regelbasierter Satz („Ab 15 Uhr Regen, morgen 8° kühler“) | Forecast | String | S01 |
+| `SettingsRepo` | Einheiten, Theme, Animationen | – | Flow<Settings> | F06 |
+
+### Hintergrundjobs (WorkManager)
+
+| Job | Takt | macht |
+| --- | --- | --- |
+| `RefreshWorker` | periodisch 30 min (Netz vorhanden), Batterie nicht niedrig | alle Orte + Widgets aktualisieren |
+| `AlertWorker` | 15 min | Warnungen abrufen, neue severe/extreme → Notification |
+| `RainSoonWorker` | 15 min, nur Orte mit `rain_alerts` | `minutely_15` prüfen → „Regen in ~X Min“ |
+| `TomorrowWorker` | täglich zur eingestellten Uhrzeit | Morgen-Vorhersage als Notification |
+| Widget-Update | nach jedem Refresh + `updatePeriodMillis` als Fallback | `GlanceAppWidget.updateAll()` |
+
+## Design-Architektur (Priorität)
+
+- **Theme:** Material 3 Expressive, Dynamic Color (Monet) **plus** eine eigene, zur Wetterlage passende Farbpalette (z. B. klar/Tag → Blau-Gelb, Gewitter → Violett-Grau). `WeatherTheme` liefert Tokens aus `replica-design`.
+- **Hintergrund-Engine:** `WeatherScene(condition, isDay, intensity, windDir)` → AGSL-Shader-Layer (Himmelsverlauf, Wolken, Niederschlagspartikel, Blitz, Nebel), mit Parallax beim Scrollen. Bei aktiviertem Battery Saver bzw. „Animationen reduzieren“ wird ein statischer Verlauf gezeigt.
+- **Karten:** wiederverwendbare `MetricCard` mit expressiven Formen (Cookie-/Pill-Shapes), eigene Gauges (UV-Bogen, Windkompass, Sonnenbogen, AQI-Skala) in Canvas, alles eigene Icons (z. B. Material Symbols, Apache 2.0, plus eigene Wettericons).
+- **Motion:** Shared-Element-Übergang von der Städteliste zur Stadt, Kartendrag mit Spring-Animationen, Haptik beim Einrasten.
+- **Edge-to-Edge**, prädiktive Zurück-Geste, Two-Pane-Layout ab Breite „medium“ (Tablet/Foldable).
+
+## Widgets (Priorität)
+
+| Widget | Größen | Inhalt |
+| --- | --- | --- |
+| Jetzt | 2×1, 2×2 | Icon, Temperatur, H/T, Ort |
+| Stündlich | 4×2 | Jetzt + 5–6 Stunden |
+| Täglich | 4×2, 4×3 | Jetzt + 5 Tage mit Temperaturbalken |
+| Groß/Komplett | 4×4 | Jetzt, stündlich, täglich, Warnhinweis |
+| Pille/Glance | 4×1 | Datum + Wetter in einer Zeile (eigener At-a-Glance-Ersatz) |
+
+- Responsive `SizeMode.Responsive`, ein Widget-Typ pro Inhalt mit Größen-Breakpoints.
+- Stile: Dynamic Color, Wetterlage als Hintergrund (vorgerenderte Bitmaps, weil Widgets keine Shader können), transparent.
+- Konfigurations-Activity: Ort wählen (oder „aktueller Standort“) und den Stil, mit Live-Vorschau.
+- Tippen öffnet direkt die jeweilige Stadt, das Refresh-Icon stößt `RefreshWorker` an.
+
+## Was beißt
+
+- **Zeitzonen/DST:** Stunden und Tage immer in der Zeitzone des Orts (`timezone=auto`) zeigen, nicht in der des Geräts.
+- **Doze/Akkuoptimierung:** WorkManager-Takte sind nicht garantiert. Bei OEMs mit aggressivem Energiesparen auf die Ausnahme hinweisen.
+- **Ohne Play Services:** Kein Fused Location. Für schnelle Ergebnisse `getCurrentLocation` des Netzwerk-Providers mit Timeout nutzen, sonst die letzte bekannte Position.
+- **Rate Limits:** Open-Meteo erlaubt 10k Aufrufe am Tag, kein Problem. Nominatim erlaubt 1 Req/s, also cachen. RainViewer-Tiles müssen gecacht werden.
+- **Widget-Grenzen:** RemoteViews können keine Animationen und keine Shader, daher Hintergründe vorrendern. Updates sind limitiert, also ereignisgesteuert aktualisieren.
+- **Offline:** Der Cache wird immer angezeigt, mit dem Stand „vor X Min“. Ab 3 h wird er als veraltet markiert.
+- **Lizenz/Attribution:** Open-Meteo, DWD, RainViewer und OSM kommen in die About-Seite und ins Kartenoverlay.
+- **Performance:** Shader auf alten Geräten drosseln (adaptive Qualität), Hintergrund pausieren, wenn er nicht sichtbar ist.
+- **DSGVO:** Es gibt kein Tracking und kein Analytics. Koordinaten gehen nur an die Wetter-APIs, auf 2 Nachkommastellen gerundet.
+
+## Build-Reihenfolge
+
+1. **Vertical Slice** (S01, S14): GPS → Open-Meteo → Room → Home mit Hero, stündlicher Leiste und 10-Tage-Liste, schlicht gestaltet. Tabellen `locations`, `forecast_cache`. Beweist den Stack ohne GMS.
+2. **Design-Fundament** (S01): Theme, `WeatherScene`-Shader für die 6 Grundlagen (klar, bewölkt, Regen, Schnee, Gewitter, Nebel × Tag/Nacht), `MetricCard` und alle Must-Karten.
+3. **Widgets** (S12): Jetzt, Stündlich, Täglich, Konfiguration, `RefreshWorker`. Tabelle `widget_config`.
+4. **Orte** (S02, S03): Suche, Hinzufügen, Swipe-to-Delete, Pager zwischen Städten.
+5. **Warnungen** (S11, S13): DWD/MeteoAlarm, Banner, `AlertWorker`. Tabelle `alerts`.
+6. **Einstellungen** (S07–S09): Einheiten, Theme, Animationen.
+7. **Should:** Radar (S06), Kartenreihenfolge (S10, `card_layout`), AQI, Druck, Sicht, Detailansichten (S04, S05), großes Widget und Pillen-Widget, Regen-Benachrichtigung.
+8. **Could:** Brief, Pollen, Morgen-Benachrichtigung, Vibrationen, Tablet-Layout.
+9. **Fixes** aus `/replica-entrepreneur`.

+Not yet verified on a real device: location without Play Services, network on device, widgets on the launcher, WorkManager timing.

+# Komponenten: Wetter-Klon (Compose, Material 3 Expressive)
+
+Tokens: `tokens.json` → `Tokens.kt` (über `gen_theme.py`). Komponenten verwenden nur Rollen (`WColor.onScene`), nie rohe Hex-Werte.
+Icons: Material Symbols Rounded (Apache 2.0) für die UI. Die Wettericons sind eigene oder [Meteocons](https://github.com/basmilius/weather-icons) (MIT), animiert über Lottie. Kein Google-Artwork.
+Schrift: Roboto Flex (OFL). Texte sind alle neu geschrieben, auf Deutsch.
+
+## Grundregel Kontrast über Szenen
+
+Text auf dem animierten Himmel nutzt `on-scene`, bei hellen Szenen (Schnee, Nebel, unterer Tagesverlauf) `on-scene-dark`. Die Szene meldet ihre Helligkeit (`scene.isLight`), und das Theme wählt danach.
+Beim klaren Tageshimmel oben besteht weißer Text nur als Großtext (3,9:1). Kleiner Text dort braucht deshalb einen Scrim, einen Verlauf von 0 auf 25 % Schwarz hinter dem Hero-Kopf.
+Karten auf der Szene: `scene-card` mit 85 % Deckkraft plus Blur (API 31+, `RenderEffect`). Ohne Blur wird `scene-card` voll deckend gezeigt.

+- **HeroBlock:** zentrierte Spalte. Oben die Wetterlage (22sp), darunter die Temperatur sehr groß und **fett** (112sp, 700, nicht dünn) mit dem Wettericon direkt rechts daneben, etwa 40 % der Ziffernhöhe, oben ausgerichtet. Dann „Gefühlt 19°“ und „Höchstwert 22° · Tiefstwert 14°“. Am Tag ist der Text dunkel auf hellem Himmel, nachts weiß. Es gibt keinen Scrim, die hellen Szenen sind entsprechend hell gewählt.
+- **Szene:** ruhiger, weicher Verlauf mit großen, unscharfen, langsam treibenden Formen (Wolkenschemen, Hügel). Keine fotorealistische Darstellung. Bei Niederschlag fallen dezente Partikel.
+- **Karten-Container:** deckend (`card` bzw. `dark-card`, warm getöntes Neutral), Radius 28, Padding 20. Die Kopfzeile besteht aus einem Outline-Icon und dem Titel (card-title). Zwischen den Karten 12 dp Abstand, nach außen 16 dp Rand.
+- **HourlyStrip:** Die Spalten zeigen Temperatur, darunter Icon, darunter Niederschlag in % (`precip-text`, klein), darunter die Uhrzeit. Die aktuelle Stunde trägt einen **Cookie-Chip** (`now-chip`) hinter der Temperatur, das Label heißt „Jetzt“.
+- **DailyList:** **horizontal** scrollende Reihe vertikaler **Kapseln** (`pill`, Radius 24, ca. 56×190 dp). In jeder Kapsel stehen Höchstwert, Tiefstwert (muted), Icon, Niederschlag in % und Tag plus Datum. Ein Tipp auf die Kapsel öffnet S04.
+- **DayDetail (S04, bestätigt):** oben eine Kapselreihe, die gewählte Kapsel ist hervorgehoben (`pill-selected`). Darunter Datum, Ort, „24°/14°“ (day-range 56sp) mit Icon, Wetterlage, die stündliche Vorhersage für diesen Tag und darunter dieselben Detailkarten.
+- **Detailkarten:** Raster mit 2 Spalten aus quadratischen Kacheln, **Formen statt einheitlicher Karten**:
+  - Wind: Kreis, darin ein abgerundetes Dreieck als Blob (`fill-*`), gedreht in die Windrichtung, mittig Wert und Einheit, darunter „Aus NW“
+  - UV: Cookie mit 12 Wellen, Wert und Stufe, Punkte auf einem unteren Bogen, der aktive Punkt farbig
+  - Sichtweite: Kreis mit gewellter Innenfläche (`fill-tertiary`), Wert und Einheit
+  - Luftfeuchte: Rechteck, Füllstand mit gewellter Oberkante, Höhe = %, unten ein runder Chip mit dem Taupunkt
+  - Luftdruck: Kreis mit 270°-Bogenanzeige, Wert groß, Einheit darunter
+  - Sonne: Rechteck mit gefülltem Sinus-Hügel über der Horizontlinie, der Nachtteil dunkler, Sonnenpunkt auf der Kurve, Aufgang und Untergang als Zeiten
+  - Luftqualität: Rechteck mit Verlaufsbalken und Knopf, Wert, Einstufung („Gute Luftqualität“); ohne Daten wird „– –“ gezeigt
+- **NowcastCard (neu):** „Regen ab 09:15“ als Titel, Untertitel „Leichter Regen von 09:15 bis 10:45“. Ein Punkt-Balkendiagramm zeigt die nächsten 2–3 Stunden in 15-Minuten-Schritten, die Y-Achse in drei Stufen (leicht, mäßig, stark). Ein Marker-Chip am Beginn, die X-Achse mit Uhrzeiten. Die Karte erscheint nur, wenn in den nächsten 3 Stunden Niederschlag kommt. Daten: Open-Meteo `minutely_15`.
+- **BriefCard:** wie eine normale Karte mit Icon, Titel „Kurz gesagt“ und einem Chevron zum Auf- und Zuklappen. Darunter 2–3 Sätze Text in body.
+- **Vorschau eines Orts (S15, neu):** Ein gesuchter Ort öffnet die volle Ansicht mit einem Button „Speichern“ oben rechts (gefüllter Pill-Button, Tonal).
+- **Abweichungen, die bewusst eigen bleiben:** eigene Icons und Szenen, ein eigener Akzent erst in `/replica-brand`, eigene Texte. Die Kartenformen sind M3-Expressive-Standardformen (`MaterialShapes`: Cookie, Circle, Triangle, Wavy), damit ist nichts vom Original nachgezeichnet.

+## Feature matrix
+
+See `features.csv`. Must: 18, should: 14, could: 7, skip: 4 (design + widgets raised to must).
+
+## Out of scope (cannot or should not be cloned)
+
+- Google's own forecast and nowcasting models (MetNet / NowCast): proprietary. Replace with Open-Meteo (forecast, AQI, pollen, geocoding), DWD / MeteoAlarm (alerts), RainViewer or DWD radar (map).
+- Gemini-based Weather Brief and personal insights from Calendar/Gmail: Google AI and Google data. A rule- or template-based summary is the replacement, or optionally a local LLM.
+- Location sync via Google account: deliberately left out.
+- At a Glance / Pixel launcher integration: a system feature.
+- Google's illustrations, icons, animations and the "Froggy" art: original assets have to be made from scratch.
+
+## Size
+
+Screens 15, flows 9, entities 7. Hard parts: (1) the precipitation map with timeline (tile sources, licences, animation), (2) reliable background notifications/alerts without Play Services (WorkManager, Doze), (3) polished animated backgrounds + homescreen widget. Size: M (a few weeks) for a native Android app (Kotlin/Compose).
