 - BLS 4.0 (~7140 Lebensmittel) ist frei nutzbar (MRI / blsdb.de); Dateien nicht im Git.
 - Mapping ohne KI: Normalisierung + exakter Lookup (User vor Global) + Bestätigung neuer Namen.
 - Öl/Supplement mit Etikett (EPA/DHA, Vitamine) ist **ein Katalogeintrag**, keine Zutatenliste. Listen sind nur Rohmischungen aus Lebensmitteln — eine Liste kann keine andere Liste enthalten. Quarkspeise = Liste, Omega-3-Öl = Lebensmittel darin.
-- Gelernte Zuordnungen bleiben dauerhaft, sind aber änder- und löschbar.
+- Gelernte Zuordnungen bleiben dauerhaft, sind aber änder- und löschbar. Nutzer-Mapping vor globalem Mapping. Globales Mapping nur auf BLS oder zentrale Admin-Foods.
+- Sichtbarkeit: persönlich (nur Owner) / zentral (alle) / BLS (alle). Vorschläge und Suche filtern danach; bei gleichem Namen gewinnt persönlich vor zentral vor BLS.
 - Ungemappte / Fertiggerichte: FDDB-Makros, keine erfundenen Mikros.
 - Fasten und „unvollständig“ sind explizite Marken, kein Auto-Schluss aus fehlendem Import.
 - Import-Policy (Profil): nachfragen / Katalog überschreiben / FDDB überschreiben / Makros behalten.
 
 ## Manuelle Lebensmittel / Supplemente
 
-Eigene Einträge (z. B. Norsan Omega-3 + EPA) speichern **dieselben Stoffwerte** wie BLS-Lebensmittel (`food_attribute_values`, immer pro 100 g). Beim Anlegen: Makros plus Suche nach weiteren Stoffen (EPA, DHA, Omega-3). Etikett „pro 8 ml“ → Portionsgröße in g angeben, Umrechnung auf 100 g erfolgt serverseitig. Einheit des Stoffs beachten (oft **g**, Etikett in mg: 1100 mg = 1,1 g). Fehlt ein Stoff im Katalog: Admin → Stoffe & Attribute.
+Eigene Einträge des Nutzers sind **persönlich** (`manual_user`). Der Admin legt **zentrale** Einträge für alle an (`manual_admin`). Beide speichern **dieselben Stoffwerte** wie BLS-Lebensmittel (`food_attribute_values`, immer pro 100 g). Beim Anlegen: Makros plus Suche nach weiteren Stoffen (EPA, DHA, Omega-3). Etikett „pro 8 ml“ → Portionsgröße in g angeben, Umrechnung auf 100 g erfolgt serverseitig. Einheit des Stoffs beachten (oft **g**, Etikett in mg: 1100 mg = 1,1 g). Fehlt ein Stoff im Katalog: Nutzer kann ihn selbst anlegen oder Admin → Stoffe & Attribute.
+
+**Nachträglich ändern:** Unter Ernährung → Tab **Lebensmittel** (persönliche Liste + zentrale Admin-Einträge, Suche). Persönliche Einträge anlegen/bearbeiten; zentrale nur lesen. Beim Zuordnen gilt die Reihenfolge persönlich → zentral → BLS. Globale Namens-Mappings (Admin) gelten für alle, dürfen aber nicht auf ein privates Nutzer-Lebensmittel zeigen. Offizielle BLS-Einträge bleiben fest. Beim Speichern gelten die Felder als Werte je 100 g, außer die Portionsgröße wird bewusst auf die Etikett-Portion gesetzt. Betroffene Tagebuch-Tage werden im Hintergrund neu berechnet. Admin → Lebensmittelkatalog → Reiter **Manuell** → Zentral anlegen.
 
 Weitere Quellen (USDA, Schweizer Nährwertdatenbank) kommen später als zusätzliche Katalogherkunft, nicht als zweite Wertetabelle.
