+# Universal CSV Import – Agent-Leitfaden
+
+**Stand:** 2026-04-09 · **Kontext:** Issue #21 (Universeller CSV-Parser), Prod-Migrationen u. a. 051–053.
+
+Dieses Dokument ist **normativ für Agenten**, die ein neues Import-Zielmodul anlegen oder bestehende Import-Pfade (Executor, Vorlagen, DB) ändern.
+
+---
+
+## 1. Architektur (Kurz)
+
+| Komponente | Pfad / Rolle |
+|------------|----------------|
+| Modul-Definitionen | `backend/csv_parser/module_registry.py` (`MODULE_DEFINITIONS`) |
+| Typ-/Einheiten-Konvertierung | `backend/csv_parser/type_converter.py`, `field_units.py` |
+| Zeilen-Aggregation (z. B. Ernährung pro Tag) | `backend/csv_parser/import_row_processing.py` |
+| Import-Ausführung | `backend/csv_parser/executor.py` |
+| Fehlertexte / Transaktions-Hinweise | `backend/csv_parser/import_errors.py` (`enrich_row_error`) |
+| Admin-Systemvorlagen | `backend/routers/admin_csv_templates.py` |
+| Nutzer-Import (Profil-Mappings) | `backend/routers/csv_import.py` |
+| Vorlagen-Validierung (strukturell + Sample) | `backend/csv_parser/template_validator.py` (`validate_csv_template`) |
+
+**Single Source of Truth** für erlaubte Zielfelder, Typen und Duplikat-Keys ist **`module_registry.py`**. Keine parallele Feldliste in Routern duplizieren.
+
+---
+
+## 2. Checkliste: Neues Zielmodul
+
+1. **`MODULE_DEFINITIONS`** um Eintrag erweitern: `table`, `fields` (Typen `date` / `datetime` / `float` / `int` / `string`), `duplicate_key`, `duplicate_strategy`, ggf. `derive_date_from_datetime_field`, `import_mode` (Spezialpfade wie Schlaf).
+2. **DB:** Migration nur nach Projektregel (`backend/migrations/NNN_*.sql`). Spaltenbreiten/Typen so wählen, dass importierte Werte (z. B. kJ→kcal, große Energiebeträge) **keinen NUMERIC-Overflow** verursachen.
+3. **`source` / CHECK-Constraints:** Wenn die Zieltabelle `source` hat, muss der Wert **`csv`** (oder der vereinbarte Import-Tag) in der DB erlaubt sein (Migration anpassen, nicht nur App-Code).
+4. **Executor:** Einfügen/Aktualisieren in `executor.py` nur über bestehende Muster (ein Cursor, **kein** verschachteltes `get_db()` im gleichen Request). Bei mehreren Zeilen pro Transaktion: bei **Zeilenfehlern** SAVEPOINT pro Zeile nutzen (siehe Activity-Pattern), damit die Transaktion nicht dauerhaft abgebrochen ist.
+5. **Trainingstyp / FK-Auflösung:** DB-Zugriffe für abhängige Entitäten (z. B. `get_training_type_for_activity_with_cursor`) **mit dem gleichen Cursor** wie der Import – keine zweite Connection aus dem Importpfad.
+6. **Vorlagen:** System-Templates in Migration/Seed pflegen (`csv_field_mappings`, `is_system=true`). `type_conversions` und `source_unit` dort setzen, wo Einheiten aus Exporten abweichen (z. B. Apple kJ).
+7. **Validierung:** Neue/angepasste Admin-Vorlagen müssen **`validate_csv_template`** passieren (Create/Update liefert bei Fehlern **422** mit `validation`). Tests für Randfälle ergänzen (`tests/test_template_validator.py` o. ä.).
+8. **API / Frontend:** Neue Admin-Endpunkte in `main.py` registrieren; Frontend **nur** über `api.js`. Bei strukturierten FastAPI-Fehlern (`detail` als Objekt/Liste) bestehende Hilfen (`formatFastApiDetail`) nutzen.
+
+---
+
+## 3. Checkliste: Bestehendes Modul ändern
+
+- Schema-Änderung: Migration + ggf. **`module_registry`**-Felder anpassen.
+- Neue Spalte im Import: Executor-Mapping, optional `type_conversions` / Validator.
+- Änderung an Duplikatlogik: `duplicate_key` / `ON CONFLICT`-Pfad im Executor prüfen.
+- Datums-/Zeit-Parsing: **`type_converter`** – ISO-Daten `YYYY-MM-DD` konsistent (**`dayfirst=False`**), Zeiten `HH:MM` ohne Sekunden unterstützen wo nötig.
+
+---
+
+## 4. Bekannte Einschränkungen (Follow-up in Gitea)
+
+- Admin **„Format prüfen“** kann `import_row_processing` derzeit weglassen; volle Parität mit dem gespeicherten Template erst beim Speichern / echten Import.
+- Nutzer-Mappings (Copy aus Systemvorlage) laufen nicht automatisch durch **`validate_csv_template`** – Tracking: **Gitea #71** (http://192.168.2.144:3000/Lars/mitai-jinkendo/issues/71).
+
+---
+
+## 5. Verwandte Regeln

+- `.claude/rules/ARCHITECTURE.md` – Router, DB, `source`-Tracking
+- `.claude/rules/CODING_RULES.md` – Kurzverweis Universal CSV
+- `.claude/rules/DOCUMENTATION.md` – Ablage technischer Specs
