 Shinkan Jinkendo — Datenbank-Migrationen
 
-**Idempotent** über `schema_migrations`: jede numerische Datei `migrations/*.sql` höchstens einmal
-als „erfolgreich“ eingetragen; bei erneutem Start werden nur noch fehlende Dateien abgearbeitet.
+**Deployment:** Beim Start importiert `main.py` dieses Modul und ruft `main()` auf, bevor FastAPI
+die App lädt (`SKIP_DB_MIGRATE=1` nur für Tests oder ohne DB). Jeder Backend-Container-Start
+wendet ausstehende Migrationen an — kein separater Deploy-Schritt nötig.
+
+**Idempotent (Runner):** Über `schema_migrations` wird jede Datei `NNN_*.sql` höchstens einmal
+als erfolgreich markiert; wiederholte Starts führen nur noch fehlende Dateien aus.
+
+**Idempotent (SQL, empfohlen):** `IF NOT EXISTS`, `ADD COLUMN IF NOT EXISTS`, `CREATE INDEX IF NOT EXISTS`,
+damit ein erneuter Lauf derselben Datei harmlos bleibt. Ohne diese Guards schützt nur der
+`schema_migrations`-Eintrag; ältere Migrationen ohne IF NOT EXISTS können bei manuell gelöschtem
+Eintrag und bestehenden Tabellen fehlschlagen.
 
 **Reihenfolge:** Alle `NNN_*.sql` nach führender Zahl (001 vor 009 vor 010 …), bei gleicher Zahl
 alphabetisch nach Dateinamen — nicht bloß String-Sortierung (vermeidet z. B. `10_` vor `9_`).
