 ## [Unreleased]
 
+## [3.6.0] – 2026-10-25
+
+### Neu
+
+- **Projekte:** Kennzahlen (Läufe, Zeit, Filament, Kosten), Tab Läufe, Einreihen / Alle einreihen, Filter Aktiv/Fertig, Deep-Link `#id`. API: `GET …/laeufe`, `POST …/einreihen`.
+- **Wand-Cockpit:** Block „Als Nächstes“ — Nochmal, Queue-Hinweis, passende Dateien (Start oder Anpassen unter Dateien).
+- **Querverlinkung:** Datei/Projekt/Spule/Auftrag/Drucker verlinkt in Protokoll, Bericht, Warteschlange, Aufträge, Material, Statistik (Projektfilter), Dateien.
+- **API für Apps:** `POST /auth/token`, QR bei Token-Erzeugung, Server-Filter für Dateien/Queue/Spulen (`limit`/`offset`, `X-Total-Count`), `?token=` für Datei-Vorschau und Assets, `/version` mit `api`/`features`, Aktions-Alias `resume`/`cancel`. Doku: `docs/internal/API.md`, `openapi.yaml`.
+- **Pi:** Umzugsanleitung Windows→Pi, Skript `scripts/pfade_umziehen.py` im `.deb`.
+- **Protokoll Verbinden:** Verdachtspaare nach Runout manuell zusammenlegen (`POST /laeufe/<id>/verbinden`). Liste zeigt Rollenwechsel, mehrere Spulen und Pausendauer.
+- **Reparatur:** `scripts/laeufe_reparieren.py` findet Alt-Paare und verwaiste Live-Läufe (Probelauf standardmäßig). Orphan-Übernahme nur bei gleicher Datei und wenn der Live-Lauf wirklich verschwindet; kein Host-Fallback auf fremde offene Drucke.
+
+### Geändert
+
+- **Projekte / Aufträge:** Liste zuerst (volle Breite); Formular und Detail nur bei Neu, Auswahl oder Bearbeiten — wie Material. Aufträge: Positionen ohne `prompt()`, Kopf-Button „Neuer Auftrag“.
+- **Layout:** `.edit-split.is-idle`, Split/Panel ab 1080px einspaltig; Pfad-Ellipsis in Tabellen; Protokoll-Hilfe einklappbar; Queue-Aktionen mit Textlabels; Jetzt-Seite zeigt „Alles erledigt“; Aktivität Drucker-Filter als Select; Statistik-Filter unter „Weitere Filter“; Nav Aufträge = Clipboard-Icon; Mobile-Mehr gruppiert.
+- **Material-Routing:** PLA ist PLA. Meta, Matte, Silk und die Marke halten die Queue nicht mehr an; liegt die genannte Sorte am Drucker, wird sie weiter bevorzugt. Ein anderer Typ (PETG statt PLA) bleibt ein Wartegrund.
+- **mcp** auf `2.0.0` gepinnt.
+- **Lauf-Identität:** Zusammenlegen nur mit Beweis (`print_duration` fortgesetzt + Lücke ≤ 5 s, oder Watcher „druckt weiter“). Leere History-Hüllen werden nicht gespeichert. `sync_history` unter Advisory-Lock; Abzug atomar. Doku: `docs/internal/Lauf-Identitaet.md`.
+- **Queue `print_active`:** Nur `complete` = fertig. `cancelled`/`standby` werden entprellt; echter Abbruch heißt „Druck abgebrochen“, nicht „Fertig.“. Kein Auto-Retry nach Abbruch. Worker respektiert Abbruch während Upload. `print_queue.run_id` + höchstens ein `running` pro Host.
+- **Wand Runout:** Hinweis nennt ACE-Platz und verlinkt Material mit vorausgefülltem Drucker/Platz.
+- **Live-UI:** SSE `queue`/`drucker` aktualisiert Warteschlange und Protokoll.
+
+### Behoben
+
+- **Legacy-Kameras-Seite:** totes Template entfernt (Route leitete schon auf die Wand um).
+- **Laufende Charge bleibt am History-Job:** Kommt die Moonraker-Job-ID, übernimmt dieser Lauf die Nummer. Sie fällt nicht weg, nur weil der Druck noch läuft.
+- **Alte History-Jobs verbrauchen die Charge von heute:** Eine Filament-Pause öffnet eine zweite Job-ID. Bleibt die ohne Ende und ohne Dauer in der History stehen, hing Grotti sie als neuen Druck an den heutigen Tag und buchte das Filament noch einmal ab. Die Job-ID bleibt am ursprünglichen Lauf, eine leere Hülle überschreibt ihn nicht, und die Charge trägt das Startdatum des Drucks.
+- **Kontaktverlust spaltet den Druck:** Zwei fehlende Polls melden den Drucker offline, lassen den Lauf aber offen und ziehen nichts ab. Dieselbe Charge läuft weiter, wenn derselbe Auftrag wieder da ist. Erst fertig, Abbruch, Fehler oder ein anderer Auftrag schließt den Lauf.
+- **Queue bleibt auf „Druckstart kann eine Minute dauern“, während der Drucker längst druckt:** Der Abschluss hat `await_print` erst geprüft, wenn der Drucker wieder frei war, und den laufenden Druck dann als Start-Timeout gewertet.
+- **Strombericht ohne Düse/Bett nach Pause:** Beim Zusammenlegen zweier History-Jobs bleiben Temperatur- und ED-Proben am Lauf. Vorher wurden die Proben des Folgejobs gelöscht, der Bericht fiel auf die Grundlast zurück.
+- **Filament-Pause spaltet das Protokoll:** Setzt Anycubic nach dem Fortsetzen eine neue History-Job-ID, bleibt es ein Lauf. Der Abbruch-Teil wird nicht noch einmal als ganzer Druck abgezogen.
+- **Materialwechsel öffnet trotzdem einen zweiten Auftrag:** Moonraker liefert die History neueste zuerst. Die Fortsetzung kam vor dem abgebrochenen Teil an die Reihe, fand keinen Vorgänger und wurde ein eigener Lauf; der alte Teil wurde als Abbruch abgezogen. Der Abgleich geht jetzt pro Drucker von alt nach neu. Eine eingeklappte Job-ID setzt den laufenden Druck nicht mehr auf „Abgebrochen“ zurück, und der zusammengelegte Lauf hat kein Ende, solange er druckt.
+- **Fertig vor History bucht doppelt:** Live-Lauf wird geschlossen ohne Abzug; History bucht. Fallback nach 10 min ohne History.
+- **Abbruch + schnelles Nochmal:** Frischer Neustart (Dauer nahe 0) wird nicht mehr als Filament-Fortsetzung zusammengelegt.
+- **Alter Lauf auf der neuen Spule:** Der History-Abgleich zieht einen Druck nur von Rollen ab, die vor dem Druckende schon existierten. Die Rolle, die gerade im ACE liegt, bekommt keine alten Jobs.
+- **Projektfilter leer neben „Wurzel“:** Ein gewähltes Projekt hebt den Ordnerfilter „Wurzel“ auf. Ein Ordner zeigt auch die Dateien in seinen Unterordnern.
+
+## [3.5.2] – 2026-10-21
+
+### Geändert
+
+- **Wenig Rest:** ACE oder Spule unter dem Dateigewicht warnt unter Dateien, bricht Start und Warteschlange nicht mehr ab. Falsche Sorte bleibt ein Wartegrund.
+
+### Behoben
+
+- **Queue „Nochmal — Start abgebrochen (Neustart)“ während der Drucker anläuft:** Nach dem Upload bleibt der Auftrag in `await_print`, bis Moonraker druckt. Die 45-Sekunden-Regel gilt nur noch, wenn der Upload-Thread weg ist. Wand und Seitenleiste zeigen „startet“ und dass es etwa eine Minute dauern kann.
+
+## [3.5.1] – 2026-10-20
+
+### Geändert
+
+- **MCP:** Server-Anweisung für Clients (Ablauf, confirm, Filament-Pause, Platten-Quittung, kein G-code), damit der Agent die Tools in der richtigen Reihenfolge nutzt.
+- **Wand:** „Aus der Warteschlange“-Strip nur noch bei Ablauf (mit Schritten); einfacher Queue-Druck zeigt nur DRUCKT.
+
+### Behoben
+
+- **Queue zu früh „Fertig.“:** Nach Start bleibt Phase `starting`, bis Moonraker `printing` meldet — alter `complete`/`standby` schließt den Job nicht mehr.
+

 ## Hinweise
 
 - Standard lauscht auf `0.0.0.0:8770` (LAN). Für Internet: Reverse Proxy mit TLS.
 - Drucker unter **Einstellungen** anlegen (kein vorgefülltes `drucker.json` nötig).
 - Öffentliches `apt install grotti` ohne Datei: kommt mit dem Repo-Server (Phase 2).

+Runout, Rolle tauschen, Fortsetzen: Anycubic schließt den History-Job als `cancelled` und öffnet eine neue Job-ID. Beobachtet am 2026-10-25 auf Kobra 3 A1 (`000040` → `000041`):
+
+- Der neue `start_time` liegt etwa 0,04 s nach dem `end_time` des alten.
+- `print_duration` und `total_duration` sind an beiden Einträgen gleich und laufen weiter. Der Zähler beginnt nicht bei 0.
+- `/server/history/list` liefert neueste zuerst. Grotti sortiert pro Drucker nach `start_time`, sonst kommt die Fortsetzung vor ihrem Vorgänger dran (`jobs.history_in_order`).
+- Nach dem Zusammenlegen hängt die alte Job-ID in `run_jobs` am Lauf. `store.history_job_retired` überspringt sie, sonst schreibt sie `cancelled` zurück.

+## Regel
+
+Zusammengelegt wird nur mit **Beweis**, nicht nur wegen Zeit und Dateiname:
+
+1. Der neue Moonraker-Job hat `print_duration` ≥ Dauer des Vorgängers − 30 s, und die Lücke `end→start` ist höchstens 5 s (Anycubic setzt `end_time` erst beim Fortsetzen).
+2. Oder der Watcher hat `paused → printing` bei gleicher Datei gesehen (`watcher_resume`, `printers.active_run_id`).
+
+Ein Neustart mit `print_duration` ≤ 60 s wird nie zusammengelegt.
+
+## Pfade

+## Queue
+
+In `print_active` heißt nur `complete` fertig. `cancelled`/`standby` werden entprellt (`TERMINAL_CONFIRM_HITS`). Echter Abbruch → Status `cancelled`, nicht „Fertig.“.

+Grotti steuert eine 3D-Drucker-Farm (Anycubic Kobra, Klipper/Moonraker).
+Antworte dem Nutzer auf Deutsch. Handle nur über diese Tools.
+
+Identität
+- Drucker über das Feld host (IP). Den Namen nur zur Anzeige nutzen. Hosts nie raten: erst list_printers oder get_printer.
+- Dateien über die numerische id aus list_files (Feld id), nicht über den Dateinamen allein.
+- Vor jedem Schreibzugriff den aktuellen Stand lesen.
+
+Lesen
+- Farm: list_printers (live=true). Ein Drucker: get_printer(host).
+- Läuft: list_running. Warteschlange: list_queue. Ereignisse: list_events.
+- Bibliothek: list_files. Spulen: list_spools. Filament-Fehlmenge: bedarf_lesen.
+- Kundenaufträge: auftraege_lesen. Verschleißteile: wartung_lesen.
+
+Zustand (Feld state)
+- printing: druckt. paused: Pause. standby: frei. complete: fertig, Platte oft noch belegt.
+- error: Fehler, nicht einfach neu starten. offline: nicht erreichbar.
+- progress ist 0…1. filament_empty oder pause_reason bei Pause heißt Filament leer.
+  Dann dem Nutzer sagen, die neue Spule in Grotti dem Drucker zuzuweisen, und erst danach resume_printer.
+  Eine Filament-Pause nicht blind fortsetzen.
+
+Schreiben
+confirm=true nur setzen, wenn der Nutzer diese Aktion in diesem Zug klar will. Nicht vorauseilend bestätigen.
+- enqueue_when_free: Datei in die Warteschlange. host leer = Grotti wählt den nächsten Drucker mit passender Sorte. host gesetzt = dieser Drucker, sobald er frei ist und die Platte klar ist. Das ist der normale Weg.
+- enqueue_print: sofort senden und starten. Nur wenn der Nutzer einen Sofortstart auf einem genannten freien Drucker will (state standby, Platte frei). Große Dateien brauchen oft etwa eine Minute bis zum Start.
+- Den Material-Match macht Grotti (PLA Meta ist nicht Matte und nicht Silk). Eine falsche Maschine nicht erzwingen. Eine Ablehnung wörtlich weitergeben.
+- bed_leveling=true nur auf ausdrücklichen Wunsch (Bettnetz / Auto-Level).
+- pause_printer und resume_printer während des Drucks, ohne confirm.
+- cancel_printer bricht den Druck ab und braucht confirm=true. Bei Unklarheit erst nachfragen.
+- clear_bed ist nur die Quittung „Platte ist leer“ und schiebt nichts physisch. Erst aufrufen, wenn der Nutzer sagt, das Teil ist herunter. Ohne diese Quittung startet der nächste „wenn frei“-Job nicht.
+- steer_temp (Düse und Bett in °C), steer_speed (Prozent), steer_fan (0–100): nur diese Werte. Kein freier G-code.
+
+Grenzen
+- Keine G-code-Konsole, kein Firmware-Restart, kein E-Stop, keine Benutzer- oder Token-Verwaltung. Diese Lücken nicht umgehen.
+- Im Read-only-Modus (GROTTI_MCP_READ_ONLY) schlagen Schreib-Tools fehl. Das sagen und nicht wiederholen.
+- Gesperrte Drucker und ausgeschaltete Automatik starten keine Warteschlangen-Jobs. Den Fehler nennen.
+
+Antworten
+- Kurz und konkret: Druckername, host, Datei, Zustand, was du getan hast.
+- Den Fehlertext von Grotti zitieren. Keinen Workaround außerhalb der Tools erfinden.
