+
+Ein Desktop-Modul kann zusaetzlich diese Projektdateien besitzen:
+
+- `desktop.php` fuer die Desktop-App-Metadaten und Asset-Definitionen
+- `pages/` fuer Standalone-Seiten oder iframe/native Einstiegspunkte
+- `api/` fuer modulinterne HTTP-Endpunkte
+- `assets/` fuer modulnahe CSS- und JS-Dateien

+# Mining-Checker Modul
+
+## Zweck
+
+Das Modul erfasst DOGE-Mining-Messpunkte, analysiert OCR-Vorschlaege aus Screenshots, speichert Messreihen projektbezogen und berechnet Performance-, Kurs- und Zielmetriken.

+
+## Integration
+
+1. SQL aus dem passenden Dialekt-Schema ausfuehren:
+   - MySQL/MariaDB: `sql/schema.mysql.sql`
+   - PostgreSQL: `sql/schema.pgsql.sql`
+   - `sql/schema.sql` bleibt der Rueckfall fuer bestehende Setups
+2. Das Modul nutzt bewusst dieselbe Projekt-Datenbank wie die Anwendung und legt seine Tabellen mit dem Praefix `miningcheck_` an.
+3. Modulroute ueber `/module/mining-checker` aufrufen.
+4. REST-API wird ueber `/api/mining-checker/...` vom Hauptprojekt geroutet.
+
+Hinweis:
+Wenn beim ersten API-Zugriff noch keine `miningcheck_*` Tabellen vorhanden sind, importiert das Modul automatisch das zum aktiven PDO-Treiber passende Schema.
+Seed-Daten werden dabei nicht automatisch eingespielt.
+Fuer eine manuelle Initialisierung, ein inkrementelles Upgrade oder einen Reset gibt es zusaetzlich `schema-status`, `upgrade` und `initialize`. Mit `{ "drop_existing": true }` werden vorhandene `miningcheck_*` Tabellen inklusive Daten geloescht und das Schema neu angelegt.
+
+## OCR-Hinweis
+
+Das Modul unterstuetzt einen OCR-Provider-Stack. Standardmaessig wird zuerst `ocr.space` verwendet und danach optional auf lokales `tesseract` zurueckgefallen.
+
+Empfohlene Umgebungsvariablen:
+
+- `MINING_CHECKER_OCR_PROVIDERS=ocrspace,tesseract`
+- `MINING_CHECKER_OCR_SPACE_URL=https://api.ocr.space/parse/image`
+- `MINING_CHECKER_OCR_SPACE_API_KEY=...`
+- `MINING_CHECKER_OCR_SPACE_LANGUAGE=eng`
+- `MINING_CHECKER_OCR_SPACE_ENGINE=2`
+- `MINING_CHECKER_OCR_SPACE_SCALE=true`
+- `MINING_CHECKER_OCR_SPACE_DETECT_ORIENTATION=true`
+- `MINING_CHECKER_OCR_SPACE_IS_TABLE=false`
+- `MINING_CHECKER_OCR_SPACE_TIMEOUT=25`
+- `MINING_CHECKER_TESSERACT_BIN=/usr/bin/tesseract`
+- `MINING_CHECKER_TESSERACT_LANG=eng`
+
+Laut OCR.space-Doku wird `POST https://api.ocr.space/parse/image` mit `file`, Header-`apikey`, optional `language`, `scale`, `detectOrientation`, `isTable` und `OCREngine` verwendet. Der Modulparser wertet die OCR.space-Felder `ParsedResults`, `ParsedText`, `IsErroredOnProcessing`, `ErrorMessage` und `OCRExitCode` aus. Quellen: https://ocr.space/ocrapi
+
+## Wechselkurse und Waehrungen
+
+Der Mining-Checker speichert keine eigenen FX-Snapshots mehr, sondern referenziert die `fetch_id` aus `fx-rates`.
+Auch der Waehrungskatalog und die bevorzugten Waehrungen kommen ausschliesslich aus `fx-rates`. Der Mining-Checker fuehrt keine eigene Waehrungstabelle und keine eigene Alias-Verwaltung mehr im Laufzeitpfad.
+- `MINING_CHECKER_FX_AUTO_FETCH_ON_MISS=false`
+
+Optionaler JSON-Body:
+
+- `base`: Standard `EUR`
+- `symbols`: wird aktuell ignoriert; der Mining-Checker speichert immer den kompletten Waehrungssatz des Fetches
+
+Beispiel:
+
+```json
+{
+  "base": "EUR"
+}
+```
+
+`currencyapi.net` wird ueber das Modul `fx-rates` abgefragt. Aus dem Response werden `base`, `rates` und `updated` uebernommen; `valid` muss `true` sein. Die eigentlichen Fetches und Raten liegen im Modul `fx-rates`.
+
+Pro Abruf entsteht genau ein Datensatz in `fx-rates` mit Basiswaehrung, Provider und Stichtag. Neue Mining-Messpunkte pruefen beim Speichern, ob ein neuer FX-Fetch noetig ist; falls nicht, wird die letzte passende `fetch_id` wiederverwendet.
+
+Falls noch historische Mining-Checker-Fetches in `miningcheck_fx_fetches` und `miningcheck_fx_rates` liegen, kann `POST /api/mining-checker/v1/projects/{projectKey}/legacy-fx-migrate` diese nach `fx-rates` ueberfuehren. Danach werden bestehende Messpunkte soweit moeglich auf die passende `fx_fetch_id` aktualisiert.
+
+Fuer Auswertungen, Berichte und Listen speichert der Mining-Checker pro Messpunkt die damals passende `fx_fetch_id`. Historische Umrechnungen laufen damit gegen genau den zugeordneten `fx-rates`-Snapshot.
