Bedarf in Sidebar/Material, Drucker-Zeitfenster und Tarif in Einstellungen, helles Theme; Legacy-Token und /api/drucker entfernt; SSE/SW-Fixes gegen hängende Navigation in Chrome.

 ## [Unreleased]
 
+## [3.1.0] – 2026-10-18
+
+### Neu
+
+- **Bedarf in der UI:** Sidebar-Warnung, Karte unter Material, Chip in der Warteschlange.
+- **Start-Zeitfenster** je Drucker in den Einstellungen (Queue nur im Fenster).
+- **HT/NT-Tarif** in den Energie-Einstellungen.
+- **ntfy-Test** wie bei Telegram.
+- **Helles Theme** (Dunkel / Hell / System) pro Browser.
+- Statistik: Balkendiagramme Druckzeit/Verbrauch, Empty-State ohne Daten.
+- Wartung: KPIs, Empty-State, Reset mit Bestätigung (`armButton`).
+
+### Geändert
+
+- Cockpit und Warteschlange nutzen SSE/`createPoller` statt hartem 5‑s-Intervall.
+- Shared-`config.token` wird nicht mehr als Auth akzeptiert — nur noch Session und `grt_…`-Tokens.
+- Legacy-Alias `GET /api/drucker` entfernt (nur `/api/v1/drucker`).
+
+### Behoben
+
+- SSE unter waitress: Hop-by-Hop-Header `Connection` entfernt (sonst Fehler auf `/api/v1/stream`).
+- Bedarf: Material/Farbe aus `files.filaments` statt nicht existierender Spalten.
+- Chrome: Service-Worker lieferte bei Fehlern die Startseite statt der angeklickten Route; „Mehr“-Dialog blockierte die Navigation; SSE und Poller liefen parallel und stauten Verbindungen.
+
+## [3.0.0] – 2026-10-18
+
+Major: neue Tabellen (Aufträge, Wartung), Projekte/Ideen → Aufträge, Navigation umgebaut, Dev-Server → waitress, Schema über Migrationen.
+
+**Vor dem Update:** `pg_dump` der Datenbank. Danach Grotti starten (Migrationen 003–009 laufen automatisch).
+
+### Neu
+
+- **Aufträge:** Kunden, Positionen (Datei × Menge), Fortschritt, Einreihen, Lieferschein; Migration aus Projekten/Ideen; API `/api/v1/kunden`, `/api/v1/auftraege`; MCP-Lesetools.
+- **Ausschuss-Pflicht:** Dialog beim „Platte geräumt“ (Urteil, Grund, Stückzahlen).
+- **Wartung:** Laufzähler und Verschleißteile, Seite `/wartung`.
+- **Bedarf:** Queue vs. Spulenrest (`GET /api/v1/bedarf`).
+- **ntfy** neben Telegram; **Backup**-ZIP (pg_dump + data/); **Zeitfenster** je Drucker; optional HT/NT-Tarif.
+- **SSE** Live-Stream `/api/v1/stream`, Verbindungsbanner, PWA-Manifest/Service-Worker.
+- Migrationen unter `grotti/migrations/`, Connection-Pool, Indizes, Sample-Retention.
+- Mobile-Nav mit „Mehr“-Sheet; Anleitungen Aufträge und Wartung.
+
+### Geändert
+
+- Server: waitress; Threads starten in `server.main()`.
+- Navigation: Aufträge statt Projekte/Ideen; Wartung; Dateien-/Statistik-Icons.
+- Kontrast `--faint`, `prefers-reduced-motion`, Touch-Ziele, Print-CSS.
+- Upload-Whitelist, Host-Validierung, ProxyFix, Settings-Lock, `?token=` nur Bilder.
+- Spulenabzug History ohne blinde Rate; Chargen-Locks; MCP `temp`/`percent`.
+
+### Behoben
+
+- Hängende Queue-Starts nach Neustart; Worker-Rollback; `snapshot()`-Exceptions.
+- Toast-Dedupe; ACE-Map bei Send-Vorbereitung; Spulenwarnung mit ACE.
+
+## [2.10.0] – 2026-10-18
+
+### Neu
+
+- Einstellungen: Slice-Ordner (`watch_dir`) setzen; Repo-Ordner `slice/` als Standard (Inhalt gitignored).
+- Orca-Nachbearbeitung: `scripts/orca_senden.py` lädt den Export nach Grotti und öffnet `/dateien?file=…` (Drucker, ACE, Einreihen in der UI); Anleitung unter Doku.
+- Bibliothek: Ordner unter dem Slice-Pfad anlegen und Watch-Dateien verschieben (ID/Projekt bleiben); API `…/dateien/ordner`, `…/verschieben`.
+- Bibliothek: Filter Material und Ordner, Sortierung (Neueste / Name / Material / Ordner / Druckzeit / Gewicht), Suche auch in Material und Projekt; Filter bleiben im Browser; Gruppenköpfe bei Sort Material/Ordner.
+- Cockpit: Verlauf (Temp/ED) des aktuellen oder letzten Drucks, Link zum Bericht; gemeinsame Chart-Hilfe in `api.js`.
+- Druckbericht-Verlauf: Zeitachse (links °C, rechts ED %), gestrichelte Soll-Linien, Einschaltdauer Düse/Bett; Aufheizen wird dichter erfasst.
+- Stromschätzung aus ED: Einstellungen → Düse-/Bett-Watt; Bericht zeigt kWh (ED oder pauschal).
+- Einstellungen → Dieser Browser: Zeitzone für Anzeigezeiten (Browser automatisch oder z. B. Europe/Berlin).
+
+### Geändert
+
+- Energie-Defaults: Grundlast 40 W (Elektronik), Düse 60 W, Bett 220 W; Hinweis in den Einstellungen, wenn Düse/Bett 0 (nur pauschal).
+- Druckbericht: Start/Ende als lesbare Ortszeit (`17.10.2026, 15:09 – 15:46`) statt ISO.
+- Sidebar **Läuft jetzt**: eine Zeile pro Drucker (Name · % · Fertig-Uhr), Fortschritt in der Zeile; Klick öffnet die Warteschlange, × bricht ab.
+- Spulenakte: KPI-Kacheln statt Fließtext; Druckzeilen mit Datum, Charge `D-…`, Kurzname, Gramm und Status.
+- Material-Spulenformular: Marke, Chargen und Technik unter „Weitere Angaben“ eingeklappt.
+- Druck-Etikett: „Soll … g“ statt „Ziel“ (Slicer-Filamentmenge, wie im Bericht).
+- Tasten-Grenze im Ablauf: dokumentierter Default 3 mm (kalt an der Düse sonst Fehlalarm); Anleitung und Technik-Notiz angepasst.
+- `requirements.txt` mit festen Versionen; `requirements-dev.txt` mit pytest.
+- Unbenutzte Helfer entfernt (`printers.load_printers`, Mesh-Vergleich 3×3, `fetch_bed_mesh`, `last_sample_at`, …).
+
+### Behoben
+
+- Druckbericht: Objekt-Etiketten kollidieren nicht mehr, wenn dieselbe Chargennummer schon an einem anderen Lauf hängt (Seite `/protokoll/<id>` lieferte 500).
+- Orca-Nachbearbeitung: Export unter dem Slice-Ordner (inkl. Unterordner) wird als Watch-Datei übernommen statt flachem Upload; Temp-Dateien `.gcode.pp` erkannt.
+- Material: Rest-Gramm im Spulenformular akzeptiert Dezimalwerte (Abzug lieferte z. B. 501,34 g — Browser blockierte bei `step=1`).

+Gilt für **OrcaSlicer** und **AnycubicSlicerNext**. Pfade anpassen. Der Slicer hängt den Export-Pfad selbst an.
+
+Unter **Gerät / Drucker** keinen Print-Host (Moonraker) eintragen — sonst geht der Job am Grotti-Senden vorbei.
+
+## Ablauf
+
+1. In Orca slicen und **G-code exportieren** (Platte schreiben). Als Ziel den Slice-Ordner wählen — **Unterordner** (z. B. `slice\Gridfinity\…`) gehen: Grotti legt die Datei dort ab und liest den Watch neu. Export außerhalb des Slice-Ordners landet als Upload (ohne Ordner-Verschieben).
+2. Der Browser öffnet `/dateien?file=…` mit der neuen Datei.
+3. Drucker wählen, unter Optionen Farbe → ACE-Platz, **Jetzt** / **Wenn frei** / **Nächster freier**, dann **Starten**.
+
+Test ohne Orca:
+
+```powershell
+D:\Projekte\Grotti\.venv\Scripts\python.exe D:\Projekte\Grotti\scripts\orca_senden.py C:\pfad\datei.gcode
+```
+
+## Störungen
+
+| Symptom | Check |
+| --- | --- |
+| Meldungsfenster „Config fehlt“ | `data/orca-senden.json` anlegen |
+| „Grotti nicht erreichbar“ | Server läuft? `url` stimmt? |
+| „Token fehlt oder stimmt nicht“ | Token neu anlegen, in der JSON eintragen |
+| Browser ohne Datei / Login | Einmal anmelden; Deep-Link behält `?file=` nach dem Login |
+| Skript läuft nicht | Export wirklich speichern; Zeile im **Druckerprofil**; Python-Pfad prüfen |
