+Daraus folgen genau zwei Arten von Einheiten-Einstellungen:
+
+**1. Sammelwerte, die in die Agenten geschrieben werden.** Alles, was es auch am Agenten
+gibt: Tagesbudget, Modell, Verhalten beim Budgetende (#716). Wer für das Marketing das
+Tagesbudget setzt, schreibt den Wert in jeden Agenten darunter. Die Einheit merkt sich den
+Wert nur als **Vorgabe für Agenten, die neu hinzukommen**, nie als Grenze, die im
+Hintergrund gilt. Danach steht am Agenten, was gilt, und nur dort.

+  Ausreißer, ob er mit überschrieben wird.
+- Die Vorschau bietet zwei Rechenwege: **ein Wert je Agent** („jeder bekommt 10 $") oder
+  **ein Gesamtbetrag, verteilt** („das Marketing bekommt 100 $"). Beim Verteilen
+  vorgeschlagen: im Verhältnis der bisherigen Werte, damit ein Spezialist seinen
+  größeren Anteil behält.
+
+**2. Regeln, die es nur an der Einheit gibt.** Sie haben kein Gegenstück am Agenten und
+können deshalb mit nichts konkurrieren:
+
+- **Rechte-Obergrenze.** „Was die Einheit nicht darf, kann ein Mitglied nicht bekommen"
+  bleibt, weil sie eine Sicherheitsgrenze ist. Sie wird **beim Schreiben** geprüft, nicht
+  zur Laufzeit darübergelegt: Eine Rechteänderung am Agenten, die über die Obergrenze
+  hinausginge, wird abgewiesen. Senkt man die Obergrenze, zeigt die Vorschau, welchen

+- **Eskalation:** Das Werkzeug `Escalation` hat jeder Agent, ohne dass man es freischalten
+  muss. „Ich komme nicht weiter“ ist keine Berechtigung. Der Vorgang geht an die eigene

+  - `handle`: sie erledigt es selbst

+## 7a — Fremde Laufzeiten
+
+*Ergänzt am 2026-09-24, angeregt durch Paperclip. Items #712, #713.*
+
+Der vorige Abschnitt legt fest, dass nur die Entwicklungsabteilung Code hervorbringt.
+Daraus folgt eine Frage, die bisher offen war: **Womit programmiert sie?** Ein
+nachgebautes Schreib-und-Ausführ-Werkzeug von uns wird nie so gut wie Claude Code, das
+auf nichts anderes ausgelegt ist. Und mit einem Abo kann es billiger sein als Tokens über
+OpenRouter.
+
+Also bekommt jeder Agent eine **Laufzeit**:
+
+| Laufzeit | Was läuft | Wofür |
+|---|---|---|
+| `native` | unsere Engine mit OpenRouter, wie heute | Voreinstellung, alles außer Programmieren |
+| `claude-code` | Claude Code im Kopflos-Modus | die Entwicklungsabteilung |
+| `codex` | OpenAI Codex CLI | dasselbe, anderer Anbieter |
+| `command` | ein Befehl, dessen Ausgabe das Ergebnis ist | Sonderfälle |
+| `http` | ein Aufruf an einen fremden Dienst | Agenten, die woanders laufen |
+
+**Was die Instanz behält:** Organisation, Taskboard, Budget, Audit, Freigaben. **Was die
+fremde Laufzeit übernimmt:** die Arbeit innerhalb eines einzelnen Laufs. Paperclip trennt
+das vollständig: *„control plane, not execution plane"*. Wir tun das nicht, und das ist
+Absicht. Unsere Sicherheit liegt in der Ausführung (StagingGate, Werkzeugrechte,
+UntrustedContent). Eine fremde Laufzeit ist deshalb die Ausnahme für einen bestimmten
+Zweck, nicht das Modell für alles.
+
+### Eine fremde Laufzeit gilt als weniger vertrauenswürdig
+
+Was innerhalb von Claude Code geschieht, sieht keine unserer Prüfstellen. Daraus folgen
+vier Regeln:
+
+1. **Eigener Arbeitsplatz.** Ein Worktree oder eine Sandbox (#654), nie der
+   Arbeitsbereich der Instanz selbst.
+2. **Freigabelisten statt Rechte-Umgehung.** `--allowedTools` und `--max-turns`, nie
+   `--dangerously-skip-permissions`. Bei Paperclip ist die Umgehung die Voreinstellung;
+   bei uns ist sie ausgeschlossen.
+3. **Das Ergebnis ist ein Vorschlag.** Ein Diff oder ein fertiges Skript zur Abnahme, nie
+   ein direkter Einsatz. Ob es eingesetzt wird, entscheidet die Lieferkette aus
+   Abschnitt 7 (#695). Dass es Claude Code geschrieben hat, erspart keine Prüfung.
+4. **Nach außen nur über uns.** Mit Taskboard, Leitung und Ablage spricht die fremde
+   Laufzeit über einen **MCP-Server, den die Instanz je Lauf bereitstellt** (#713). Jeder
+   Aufruf dort durchläuft dieselbe Kette wie ein nativer Werkzeugaufruf. Der Server
+   bietet nur an, was der Agent laut Konfiguration hat, und ist damit kein zweiter Weg
+   an den Rechten vorbei. Das Token gilt einen Lauf lang und wird nie in der
+   Befehlszeile übergeben.
+
+### Kosten, die nichts kosten
+
+Mit einem Abo kostet ein Lauf 0 $ und verbraucht trotzdem etwas: Kontingent. Die
+Token-Zahlen aus `--output-format stream-json` gehen deshalb wie jeder andere Lauf in
+RunUsage. In der Kostenanalyse (Abschnitt 8a) erscheinen sie als Kontingentverbrauch, nicht
+als „kostenlos". Sonst wird genau die Abteilung unsichtbar, die am meisten Tokens
+verbraucht.
+
+### Zwei Vorbehalte vor dem Bau
+
+- **Das Kontingent teilt der Mensch mit sich selbst.** Ein Pro-Plan, auf dem die
+  Entwicklungsabteilung läuft, ist derselbe, mit dem der Mensch arbeitet. Entweder ein
+  eigener Account oder eine Vorfahrtsregel, die die Abteilung anhält, bevor der Mensch
+  an die Grenze stößt.
+- **Die Nutzungsbedingungen sind nicht geprüft.** Ob der automatisierte Dauerbetrieb
+  eines Verbraucher-Abos durch ein Agentensystem gedeckt ist, ist offen. Deshalb werden
+  beide Anmeldewege gebaut, Abo und API-Schlüssel, und die Entscheidung bleibt eine
+  Frage der Konfiguration statt eine des Umbaus.

+### Was liegen bleibt, wenn das Budget endet
+
+*Ergänzt am 2026-09-24 auf Hinweis des Nutzers. Item #716.*
+
+Um 22:30 ist das Tagesbudget aufgebraucht, und für den Rest des Tages stehen noch 100
+Läufe an. Lässt man sie verfallen, fehlt Arbeit. Holt man sie nach, fressen sie das
+Budget des nächsten Tages.
+
+**Heute gibt es dafür schon ein Verhalten. Nur hat es niemand entschieden.** Der Ausfall
+wird vermerkt (seit #608 als RunReceipt mit `BudgetExceeded`), aber nicht an der Aufgabe
+und nicht zusammengefasst. Einmalige Aufgaben werden alle 30 Minuten erneut versucht und
+laufen nach Mitternacht still zu Lasten des neuen Tages. Wiederkehrende verfallen still,
+weil ihr Termin schon beim Beanspruchen verbraucht ist. Beides kann richtig sein, aber
+nicht, ohne dass es jemand festlegt. Die Tagesgrenze ist die lokale Mitternacht.
+
+Der Vorschlag ist eine Einstellung je Agent, was mit einem Lauf geschieht, der am Budget
+scheitert:
+
+| Regel | Was geschieht | Voreinstellung für |
+|---|---|---|
+| `expire` | verfällt, wird an der Aufgabe vermerkt | wiederkehrende Aufgaben: Der nächste Termin kommt ohnehin, ein verpasster Stundenbericht ist vom nächsten überholt |
+| `catch_up_once` | alle verfallenen Termine werden zu **einem** Nachholauf zusammengefasst | — (sinnvoll für den Tagesbericht, dessen nächster Termin erst in 24 Stunden käme) |
+| `carry_over` | wird mitgenommen | einmalige Aufgaben: echte Arbeit, die nicht verschwinden darf |
+
+Dazu gilt: **Der neue Tag hat Vorfahrt.** Nachholläufe kommen nach den regulär fälligen,
+unterhalb jeder Priorität, und sie nutzen nur den **Spielraum**, den der Rest des Tages
+nicht braucht: Grenze minus Verbrauch, minus die Reservierung laufender Läufe, minus der
+Bedarf der noch geplanten Läufe bis Mitternacht, minus 10 % Reserve. Ohne diese Regel
+schiebt ein einziger überzogener Tag seinen Ausfall Tag für Tag vor sich her, statt ihn
+aufzulösen. *Beim Bau am 2026-09-24 geändert:* Das Konzept sah hier zunächst einen
+pauschalen Anteil von 25 % vor. Ein fester Anteil ist an einem vollen Tag zu viel und an
+einem ruhigen unnötig wenig; der Spielraum folgt dem tatsächlichen Plan, und dieselbe
+Rechnung trägt später die Füllarbeit. Eine einmalige Aufgabe, die
+nach einigen Tagen immer noch nicht drankam, geht an den Menschen: Was nie läuft, darf
+nicht unbemerkt liegen bleiben.
+
+**Vermerkt wird zweimal:** an der Aufgabe („ausgefallen: Budget erschöpft, 22:30" bzw.
+„nachgeholt am …") und in einer Tageszusammenfassung („Budget Marketing um 22:30
+erschöpft, 100 Läufe ausgefallen, 12 zum Nachholen vorgemerkt"). Die Zusammenfassung
+geht in die Abweichungsmeldung oben und ins Lagebild (Abschnitt 10a).
+
+**Besser als jede Nachholregel ist Vorbeugen.** Die Kostenprognose aus #608 weiß schon
+heute, ob das Budget für die geplanten Aufgaben reicht. Sie sollte vormittags melden,
+dass bei diesem Verbrauch um 22:30 Schluss ist. Dann kann der Mensch rechtzeitig
+nachlegen oder entscheiden, was entfällt.
+
+Zur selben Baustelle gehört die **Budgetreservierung**, der offene Rest aus #682: Noch
+prüft jeder Lauf das Budget einzeln vor dem Start, und bis zu `maxParallelTaskRuns` Läufe
+können es gemeinsam überschreiten. Erst mit einer Reservierung vor dem Lauf ist der
+Ausfall vorhersagbar statt eine Frage, welcher Lauf zuerst zugreift.
+
+### Füllarbeit und Großaufgaben
+
+*Ergänzt am 2026-09-24 auf Vorschlag des Nutzers. Item #717.*
+
+Der vorige Abschnitt regelt, was liegen bleibt, wenn das Budget nicht reicht. Die
+Kehrseite: An den meisten Tagen bleibt Budget übrig, und das verfällt.
+
+**Füllarbeit** ist Arbeit, die umfangreich, aber nicht eilig ist. Ob sie heute, morgen
+oder übermorgen läuft, ist gleich. Sie bekommt statt eines Termins eine **Frist
+„spätestens bis"** und läuft, wenn Platz ist. Rechenzentren machen das seit Jahrzehnten
+so und nennen es *Backfilling*. Ob Platz ist, entscheidet der Code:
+
+- Keine regulär fällige Aufgabe des Agenten wartet.
+- Das Restbudget des Tages, abzüglich der Prognose für die noch geplanten Läufe (#608) und
+  eines Sicherheitsaufschlags, reicht für die Schätzung der Füllarbeit.
+- Bevorzugt spät am Tag, weil die Prognose dann am wenigsten Unsicherheit hat.
+
+Rückt die Frist näher und es fand sich nie Platz, wird der Mensch gefragt: Budget
+erhöhen oder Frist verschieben. Eine Füllarbeit überschreitet ihre Frist nie still.
+
+**Großaufgaben** sind Aufgaben, deren Schätzung einen großen Teil des Tagesbudgets
+übersteigt (Vorgabe etwa 50 %). Sie werden nicht einfach angefangen. Der Agent schlägt
+einen von zwei Wegen vor:
+
+1. **Teilen.** Unteraufgaben, jede ein eigener Lauf, verbunden über die Elternaufgabe
+   (Zielkette, Abschnitt 9a). Die Teile können dann Füllarbeit sein.
+2. **Sonderbudget.** Ein Betrag für genau diese Aufgabe samt Unteraufgaben, vom Menschen
+   freigegeben. Es ist ein eigener Topf: Es hebt die Tagesgrenze des Agenten nicht an und
+   ist in der Kostenanalyse gesondert sichtbar. Damit ist es die einzige Ausnahme von
+   „Budgets bleiben am Agenten", gebunden an eine Aufgabe und nie still.
+
+**Ehrlich schätzen.** Kosten lassen sich vorab nicht genau wissen, und Modelle schätzen
+ihren eigenen Aufwand schlecht. Wo es Verlauf gibt, schätzt der Code aus dem Verlauf.
+Sonst schätzt der Agent, und die Zahl ist als Schätzung gekennzeichnet. Nach dem ersten
+Teillauf ersetzt der gemessene Wert die Schätzung.

+## 9a — Von Paperclip gelernt
+
+*Ergänzt am 2026-09-24 nach Durchsicht des Paperclip-Quellcodes. Items #714, #715.*
+
+[Paperclip](https://github.com/paperclipai/paperclip) ist das Projekt, das diesem Konzept
+am nächsten kommt: Firma, Organigramm, Budgets, der Mensch als „Board" mit Vetorecht.
+Einiges davon lohnt sich zu übernehmen, anderes bewusst nicht.
+
+### Übernommen: die Zielkette (#714)
+
+Jede Aufgabe hat eine **Elternaufgabe**, ganz oben steht das Ziel der Einheit. Damit kann
+jeder Agent beantworten, *warum* er etwas tut. Die Kette geht als kurzer Absatz in den
+Lauf mit. Das ist etwas anderes als `blocked_by`: Die Elternaufgabe ist der Zweck
+(„wofür"), der Blocker die Voraussetzung („wann"). Heute kennt `TaskItem` nur den Blocker.
+
+Daraus folgt eine zweite Fähigkeit, Paperclips *Task Watchdog*: **Kommt ein ganzer
+Teilbaum zur Ruhe**, alle Blätter erledigt, abgebrochen, blockiert oder in Prüfung, und
+es gibt keinen Weg mehr, auf dem er weiterläuft, dann prüft jemand, ob der Stillstand
+berechtigt ist. Denn Agenten hören aus falschen Gründen auf: „erledigt" ohne Beleg, eine
+Prüfung ohne Prüfer, ein falsch gelesener Blocker. Ohne Prüfung liegt der Baum einfach
+still, und niemand merkt es. Die Aufteilung ist dieselbe wie überall: Ob der Baum ruht,
+erkennt eine Abfrage (#646). Ob das in Ordnung ist, deutet die Aufsicht (#680) oder die
+Leitung. Der Prüfer gibt zurück, er bessert nicht selbst nach.
+
+### Übernommen: Rückmeldung nach Vertrauensstufe (#715)
+
+Das ist der wertvollste Gedanke aus Paperclip, und er schließt eine Lücke, die dieses
+Konzept bisher hatte. Ein Agent, der Rezensionen, Mails oder Webseiten liest, hat fremden
+Text im Kontext. UntrustedContent (K2) rahmt diesen Text beim Lesen. Schreibt der Agent
+seiner Leitung aber einen Kommentar in eigenen Worten, trägt er den fremden Text eine
+Ebene höher, in einen Kontext mit mehr Rechten, und dort ist er nicht mehr gerahmt.
+**Prompt-Injection über die Hierarchie.**
+
+Nach oben gibt es deshalb genau drei Wege:
+
+1. **Das Erledigt-Signal.** Immer an. Die Leitung wird geweckt und liest das Ergebnis im
+   Vorgang selbst.
+2. **Ein Kommentar genau eine Ebene nach oben.** Nur ein Kommentar, keine Status- oder
+   Feldänderung, nie an die übernächste Ebene oder an Geschwister. **Nur für die
+   Standardstufe.**
+3. **Für Agenten, die fremde Inhalte lesen: kein Freitext nach oben.** Stattdessen
+   verfasst der Code eine Systemmeldung „blockiert" oder „abgebrochen". Sie löst keine
+   weitere Meldung aus und geht je Zustand nur einmal hinaus.
+
+**Woher die Stufe kommt:** aus den Werkzeugen, nicht aus einer Einstellung. Wer WebFetch,
+Mail, Rocket.Chat oder ein Skript mit Außenkontakt hat, liest fremde Inhalte. Das weiß
+der Code aus der Konfiguration, eine Selbstauskunft des Agenten ist dafür nicht nötig.
+Eine Einstellung darf die Stufe nur verschärfen, nie lockern.
+
+Für Querverbindungen gilt das **„Courier Pattern"**: Wer seitlich etwas braucht, schreibt
+nicht in fremde Vorgänge, sondern legt beim Ziel eine vollständige, in sich geschlossene
+Aufgabe an. Das ist die Adressbuchregel aus Abschnitt 3 und die Stille-Post-Regel aus
+Abschnitt 5, nur zu Ende gedacht: Der Empfänger darf die Vorgänge des Absenders womöglich
+gar nicht lesen, also muss alles Nötige in der Aufgabe selbst stehen.
+
+**Reihenfolge:** vor der Freigabe durch die Leitung (#687). Eine Leitung, die Freigaben
+erteilt, darf keinen Kontext haben, in den ein Untergebener fremden Text schreiben kann.
+
+**Umsetzung (2026-09-25):**
+
+- **Die Stufe.** Jedes Werkzeug sagt über `ReadsForeignContent` selbst, ob es Text von
+  außen hereinholt. Das tun WebFetch, WebMonitor, DirectAPI, Mail, Rocket.Chat, Telegram,
+  TelegramClient, SocialMediaManager, FTP und Database. Bei Database liegt der Grund darin,
+  dass Bestellungen, Rezensionen und Feeds von außen kommen. Die Einstellung
+  `treatAsForeignReader` kann die Stufe nur anheben.
+- **Die Prüfung.** `ReportingLine` wird an allen Stellen angewandt, an denen Text nach oben
+  gehen kann: Nachricht, Spawn, `task_create` bzw. `task_update` mit einer Leitung als
+  Zuständiger, `task_comment` und die Notiz „Observed again" bei einer Dublette. Keine
+  Stufe darf Aufgaben einer höheren Ebene ändern oder wieder öffnen.
+- **Seitwärts** wird nichts abgelehnt. Nachrichten und Aufgaben von Agenten der
+  Fremdinhalt-Stufe kommen beim Empfänger aber in `<untrusted_content>` gerahmt an, mit
+  einem Hinweis auf die Herkunft.
+- **Die Rückmeldung.** Das Erledigt-Signal und die Systemmeldung erzeugt `TaskReports` im
+  Scanner. Wer eine Aufgabe vergeben hat, erfährt, wenn sie erledigt ist, in Prüfung geht,
+  blockiert oder abgebrochen wird. Die Meldung geht je Zustand einmal hinaus, gesammelt in
+  einer offenen Aufgabe je Empfänger. Sie enthält nur ID, Zuständigen und Zustand. Den Titel
+  enthält sie nur, wenn der Zuständige zur Standardstufe gehört, denn der Zuständige kann
+  den Titel ändern.
+- **Offen:** Ein Agent kann fremden Text auch über eine Datei in einem gemeinsamen Bereich
+  weitergeben. Die Ablage kennt heute nicht, wer eine Datei zuletzt geschrieben hat. Das
+  gehört zu #720 (gleichzeitiger Zugriff), wo ohnehin der Schreiber je Datei verfolgt
+  werden muss.
+
+### Übernommen, im Kleinen
+
+- **Budget in zwei Stufen.** Die harte Grenze gibt es schon (`BudgetGuard`, Tagesbudget
+  je Agent und Instanz). Dazu kommt eine Warnung bei 80 % an die Leitung, damit das
+  Anhalten keine Überraschung ist. Gehört zu #699.
+- **Gestaffelte Anzeige.** Oben die lesbare Zusammenfassung, darunter die Schritte, ganz
+  unten das Rohprotokoll. Gilt für die Teamübersicht (Abschnitt 10a) und die
+  Laufansichten aus #660.
+
+### Bewusst nicht übernommen
+
+- **Rechte-Umgehung als Voreinstellung.** Der Claude-Code-Adapter startet mit
+  `dangerouslySkipPermissions = true`, und Skills sind „open by default". Das ist das
+  Gegenteil unserer Linie, jedem Agenten nur die Rechte zu geben, die er braucht.
+- **Die ganze Firma sieht alle Arbeit.** Bei Paperclip ist das ausdrücklich gewollt.
+  Hier trennen die gemeinsamen Bereiche je Einheit bewusst (Abschnitt 3).
+- **Die reine Steuerungsebene.** Siehe Abschnitt 7a.
+- **Als Warnsignal: die Komplexität.** Allein die Regeln zur Ausführung umfassen dort
+  über 1.400 Zeilen, bei knapp 5.000 offenen Issues und im Wesentlichen einem einzigen

+letzten Sekunden gesprochen hat und wo es klemmt. Ein Klick führt zum Agenten.
+
+Bei fünf Agenten ist das eine Annehmlichkeit. Bei fünfzig ist es die einzige Art, ein
+Problem zu bemerken, bevor die Rechnung kommt oder ein Ergebnis fehlt. Abschnitt 10 sagt,
+bei fünfzig Agenten müsse etwas anderes dem Menschen sagen, wo er hinsehen soll. Das
+Lagebild ist dieses Etwas, zum Hinsehen, neben der Aufsicht (#680) zum Nachlesen.
+
+### Drei Festlegungen
+
+1. **Die Anordnung kommt aus der Struktur, nicht aus der Hand.** In n8n oder Node-RED ist
+   der Graph das Programm, dort zieht man Nodes, und das soll so sein. Hier zeigt der
+   Graph eine Wahrheit, die woanders liegt: Einheiten, Leitung, Adressbuch. Sind die
+   Nodes frei platzierbar und verbindbar, zeigt das Bild bald etwas anderes als die
+   Organisation. Verschieben per Drag & Drop kommt später als Bedienung für den Umzug
+   (Abschnitt 3), mit gestoppter Instanz, Bestätigung und Audit-Eintrag, nicht als
+   Zeichenwerkzeug.
+2. **Einheiten sind aufklappbare Container, Probleme wandern nach oben.** Hundert Nodes
+   mit wechselnden Kanten sind ein Knäuel. Standardansicht sind die Abteilungen mit einer
+   Zusammenfassung: „4 arbeiten · 1 Problem · 2 Freigaben offen". Eine Markierung am
+   Container heißt „irgendwo darin", und man klappt auf, bis man den Agenten findet.
+   Kanten zwischen Einheiten werden gebündelt, mit Zähler.
+3. **„Problem" stellt der Code fest, nicht das Modell.** Die Zustände:
+
+   | Zustand | Woher |
+   |---|---|
+   | arbeitet | aktiver Lauf |
+   | wartet auf Freigabe | offene StagedCalls |
+   | wartet auf Kollegen | laufende Delegation |
+   | Problem | letzter Lauf gescheitert, LoopGuard-Abbruch, Eskalation über Frist, Budget erschöpft |
+   | hängt | Lauf deutlich länger als bei diesem Agenten üblich |
+   | pausiert / aus | Konfiguration |
+
+   Immer Farbe **und** Symbol.
+
+### Der Klick führt in die Seitenleiste, nicht direkt in den Chat
+
+Die meisten Probleme löst man nicht im Gespräch: Oft wartet eine Freigabe, oder ein
+Werkzeug ist dreimal gescheitert. Die Seitenleiste zeigt den laufenden Lauf, den letzten
+Fehler im Wortlaut, offene Aufgaben und Freigaben (dort bestätigbar), die Kosten von heute
+gegen den Durchschnitt und den Knopf „Chat öffnen". Das ist ein Klick mehr, dafür ist
+der richtige Handgriff meist schon da.
+
+### Technik
+
+- **Datenquelle** ist der vorhandene Ereignisstrom (`MergedEventStream`). Neu sind
+  Ereignistypen mit Absender und Empfänger: Delegation, Task-Zuweisung, später Besprechung
+  und Eskalation, jeweils mit eigener Linienart. Das Verblassen nach einigen Sekunden
+  geschieht im Browser.
+- **Bibliothek:** ELK (elkjs) für das Layout, die Karten als HTML, die Linien als SVG.
+  Als Datei im `wwwroot`, nicht über ein CDN. Stufe 0 und 1 zeichneten mit Cytoscape.js
+  auf einer Canvas. Das wurde am 2026-09-24 ersetzt: Ein Canvas-Knoten kann keine
+  Agentenliste, keine Suchhervorhebung und nicht den Hausstil tragen.
+- **Gestalt (Rückmeldung 2026-09-24):** Jede Einheit bleibt immer als Karte sichtbar,
+  verbunden als Baum. Zugeklappt wird nur die Agentenliste einer großen Einheit; sie
+  zeigt dann, wer Aufmerksamkeit braucht, und „+n weitere". Eine Linie trägt die Farbe
+  des dringlichsten Zustands darunter, eine rote Linie führt also von oben zum Problem.
+  Ohne Durchklicken durch zehn Ebenen. Links ein Strukturbaum mit Suche und Zustandsfilter,
+  der die Wege zu den Treffern zeigt und den Rest abblendet. Hausstil bleibt: Radius 0,
+  App-Akzent.
+- **Nur in der WebUI.** Ein zweiter Graph-Renderer in Avalonia wäre doppelte Arbeit, die
+  auseinanderläuft. Der Desktop bettet die Ansicht ein oder verlinkt sie.
+- Englisch, Texte über Sprachpakete (#661).
+
+### Stufen
+
+- **Stufe 0**, ohne Einheiten: die vorhandenen Agenten mit Delegationskanten und
+  Zuständen. Das nützt sofort, auf der Test-VM mit sieben Agenten.
+- **Stufe 1**, mit #683: Container und nach oben gereichte Probleme. Ab hier fällt das
+  Lagebild mit dem Organigramm aus #688 zusammen; es gibt nicht zwei Ansichten der
+  Organisation.
+- **Später: die Zeitleiste.** „Wie sah das Büro um 3:12 Uhr aus?" Das kostet wenig, weil
+  nichts gelöscht wird (Abschnitt 8a): Das AuditLog wird nur neu abgespielt. Für die Frage,
+  wie ein Projekt gescheitert ist, ist das vielleicht das wertvollste Werkzeug überhaupt.
+
+### Wie andere es machen
+
+Paperclip hat ein statisches Organigramm mit einem Statuspunkt je Agent und daneben eine
+Liste der laufenden Läufe, aber keine Ansicht der Kommunikation. LangGraph Studio zeigt den
+laufenden Node eines *Ablaufgraphen*, also eines Programms, nicht einer Organisation.
+AutoGen Studio, Flowise und Langflow sind Baukästen („Nodes ziehen = Programm"), gut zum
+Bauen, schwach als Lagebild. ChatDev und AI Town zeigen das Büro wörtlich als
+Pixelgrafik: charmant, aber mit wenig Information. Die Verbindung aus aufklappbarer
+Organisation, Live-Zuständen und nach oben gereichten Problemen mit Direktzugriff hat
+keines davon.

+**Why elkjs 0.9.3 and not the newest.** It came in together with cytoscape-elk 2.3.0,

+(see below); elkjs stays at the version it was checked at. Raising it is a separate change.
+
+**Why Cytoscape is gone.** The team overview (#711) first drew its graph with Cytoscape.js
+on a canvas. A canvas node cannot hold a list of agents, a search highlight or the house
+style, so the cards became plain HTML placed by ELK, with the lines in SVG. Nothing else
+used Cytoscape.
+
+**How it is loaded.** `elk.bundled.js` is a UMD bundle and, loaded as a classic script,
+registers the global `ELK`. The team overview loads it on demand, so pages that do not draw

+# Eclipse Public License - v 2.0
+
+THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+PUBLIC LICENSE (“AGREEMENT”). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+
+## 1. DEFINITIONS
+
+“Contribution” means:
+
+-   a\) in the case of the initial Contributor, the initial content
+    Distributed under this Agreement, and
+-   b\) in the case of each subsequent Contributor:
+    -   i\) changes to the Program, and
+    -   ii\) additions to the Program;
+
+    where such changes and/or additions to the Program originate from
+    and are Distributed by that particular Contributor. A Contribution
+    “originates” from a Contributor if it was added to the Program by
+    such Contributor itself or anyone acting on such Contributor's
+    behalf. Contributions do not include changes or additions to the
+    Program that are not Modified Works.
+
+“Contributor” means any person or entity that Distributes the Program.
+
+“Licensed Patents” mean patent claims licensable by a Contributor which
+are necessarily infringed by the use or sale of its Contribution alone
+or when combined with the Program.
+
+“Program” means the Contributions Distributed in accordance with this
+Agreement.
+
+“Recipient” means anyone who receives the Program under this Agreement
+or any Secondary License (as applicable), including Contributors.
+
+“Derivative Works” shall mean any work, whether in Source Code or other
+form, that is based on (or derived from) the Program and for which the
+editorial revisions, annotations, elaborations, or other modifications
+represent, as a whole, an original work of authorship.
+
+“Modified Works” shall mean any work in Source Code or other form that
+results from an addition to, deletion from, or modification of the
+contents of the Program, including, for purposes of clarity any new file
+in Source Code form that contains any contents of the Program. Modified
+Works shall not include works that contain only declarations,
+interfaces, types, classes, structures, or files of the Program solely
+in each case in order to link to, bind by name, or subclass the Program
+or Modified Works thereof.
+
+“Distribute” means the acts of a) distributing or b) making available in
+any manner that enables the transfer of a copy.
+
+“Source Code” means the form of a Program preferred for making
+modifications, including but not limited to software source code,
+documentation source, and configuration files.
+
+“Secondary License” means either the GNU General Public License, Version
+2.0, or any later versions of that license, including any exceptions or
+additional permissions as identified by the initial Contributor.
+
+## 2. GRANT OF RIGHTS
+
+-   a\) Subject to the terms of this Agreement, each Contributor hereby
+    grants Recipient a non-exclusive, worldwide, royalty-free copyright
+    license to reproduce, prepare Derivative Works of, publicly display,
+    publicly perform, Distribute and sublicense the Contribution of such
+    Contributor, if any, and such Derivative Works.
+-   b\) Subject to the terms of this Agreement, each Contributor hereby
+    grants Recipient a non-exclusive, worldwide, royalty-free patent license
+    under Licensed Patents to make, use, sell, offer to sell, import and
+    otherwise transfer the Contribution of such Contributor, if any, in
+    Source Code or other form. This patent license shall apply to the
+    combination of the Contribution and the Program if, at the time the
+    Contribution is added by the Contributor, such addition of the
+    Contribution causes such combination to be covered by the
+    Licensed Patents. The patent license shall not apply to any other
+    combinations which include the Contribution. No hardware per se is
+    licensed hereunder.
+-   c\) Recipient understands that although each Contributor grants the
+    licenses to its Contributions set forth herein, no assurances are
+    provided by any Contributor that the Program does not infringe the
+    patent or other intellectual property rights of any other entity. Each
+    Contributor disclaims any liability to Recipient for claims brought by
+    any other entity based on infringement of intellectual property rights
+    or otherwise. As a condition to exercising the rights and licenses
+    granted hereunder, each Recipient hereby assumes sole responsibility to
+    secure any other intellectual property rights needed, if any. For
+    example, if a third party patent license is required to allow Recipient
+    to Distribute the Program, it is Recipient's responsibility to acquire
+    that license before distributing the Program.
+-   d\) Each Contributor represents that to its knowledge it has sufficient
+    copyright rights in its Contribution, if any, to grant the copyright
+    license set forth in this Agreement.
+-   e\) Notwithstanding the terms of any Secondary License, no Contributor
+    makes additional grants to any Recipient (other than those set forth in
+    this Agreement) as a result of such Recipient's receipt of the Program
+    under the terms of a Secondary License (if permitted under the terms of
+    Section 3).
+
+## 3. REQUIREMENTS
+
+3.1 If a Contributor Distributes the Program in any form, then:
+
+-   a\) the Program must also be made available as Source Code, in accordance
+    with section 3.2, and the Contributor must accompany the Program with a
+    statement that the Source Code for the Program is available under this
+    Agreement, and informs Recipients how to obtain it in a reasonable
+    manner on or through a medium customarily used for software exchange;
+    and
+-   b\) the Contributor may Distribute the Program under a license different
+    than this Agreement, provided that such license:
+    -   i\) effectively disclaims on behalf of all other Contributors all
+        warranties and conditions, express and implied, including warranties or
+        conditions of title and non-infringement, and implied warranties or
+        conditions of merchantability and fitness for a particular purpose;
+    -   ii\) effectively excludes on behalf of all other Contributors all
+        liability for damages, including direct, indirect, special, incidental
+        and consequential damages, such as lost profits;
+    -   iii\) does not attempt to limit or alter the recipients' rights in the
+        Source Code under section 3.2; and
+    -   iv\) requires any subsequent distribution of the Program by any party to
+        be under a license that satisfies the requirements of this section 3.
+
+3.2 When the Program is Distributed as Source Code:
+
+-   a\) it must be made available under this Agreement, or if the Program (i)
+    is combined with other material in a separate file or files made
+    available under a Secondary License, and (ii) the initial Contributor
+    attached to the Source Code the notice described in Exhibit A of this
+    Agreement, then the Program may be made available under the terms of
+    such Secondary Licenses, and
+-   b\) a copy of this Agreement must be included with each copy of
+    the Program.
+
+3.3 Contributors may not remove or alter any copyright, patent,
+trademark, attribution notices, disclaimers of warranty, or limitations
+of liability (‘notices’) contained within the Program from any copy of
+the Program which they Distribute, provided that Contributors may add
+their own appropriate notices.
+
+## 4. COMMERCIAL DISTRIBUTION
+
+Commercial distributors of software may accept certain responsibilities
+with respect to end users, business partners and the like. While this
+license is intended to facilitate the commercial use of the Program, the
+Contributor who includes the Program in a commercial product offering
+should do so in a manner which does not create potential liability for
+other Contributors. Therefore, if a Contributor includes the Program in
+a commercial product offering, such Contributor (“Commercial
+Contributor”) hereby agrees to defend and indemnify every other
+Contributor (“Indemnified Contributor”) against any losses, damages and
+costs (collectively “Losses”) arising from claims, lawsuits and other
+legal actions brought by a third party against the Indemnified
+Contributor to the extent caused by the acts or omissions of such
+Commercial Contributor in connection with its distribution of the
+Program in a commercial product offering. The obligations in this
+section do not apply to any claims or Losses relating to any actual or
+alleged intellectual property infringement. In order to qualify, an
+Indemnified Contributor must: a) promptly notify the Commercial
+Contributor in writing of such claim, and b) allow the Commercial
+Contributor to control, and cooperate with the Commercial Contributor
+in, the defense and any related settlement negotiations. The Indemnified
+Contributor may participate in any such claim at its own expense.
+
+For example, a Contributor might include the Program in a commercial
+product offering, Product X. That Contributor is then a Commercial
+Contributor. If that Commercial Contributor then makes performance
+claims, or offers warranties related to Product X, those performance
+claims and warranties are such Commercial Contributor's responsibility
+alone. Under this section, the Commercial Contributor would have to
+defend claims against the other Contributors related to those
+performance claims and warranties, and if a court requires any other
+Contributor to pay any damages as a result, the Commercial Contributor
+must pay those damages.
+
+## 5. NO WARRANTY {#warranty}
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN “AS IS”
+BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
+IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
+TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
+PURPOSE. Each Recipient is solely responsible for determining the
+appropriateness of using and distributing the Program and assumes all
+risks associated with its exercise of rights under this Agreement,
+including but not limited to the risks and costs of program errors,
+compliance with applicable laws, damage to or loss of data, programs or
+equipment, and unavailability or interruption of operations.
+
+## 6. DISCLAIMER OF LIABILITY {#disclaimer}
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
+SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
+EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
+PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
+CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
+EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+## 7. GENERAL
+
+If any provision of this Agreement is invalid or unenforceable under
+applicable law, it shall not affect the validity or enforceability of
+the remainder of the terms of this Agreement, and without further action
+by the parties hereto, such provision shall be reformed to the minimum
+extent necessary to make such provision valid and enforceable.
+
+If Recipient institutes patent litigation against any entity (including
+a cross-claim or counterclaim in a lawsuit) alleging that the Program
+itself (excluding combinations of the Program with other software or
+hardware) infringes such Recipient's patent(s), then such Recipient's
+rights granted under Section 2(b) shall terminate as of the date such
+litigation is filed.
+
+All Recipient's rights under this Agreement shall terminate if it fails
+to comply with any of the material terms or conditions of this Agreement
+and does not cure such failure in a reasonable period of time after
+becoming aware of such noncompliance. If all Recipient's rights under
+this Agreement terminate, Recipient agrees to cease use and distribution
+of the Program as soon as reasonably practicable. However, Recipient's
+obligations under this Agreement and any licenses granted by Recipient
+relating to the Program shall continue and survive.
+
+Everyone is permitted to copy and distribute copies of this Agreement,
+but in order to avoid inconsistency the Agreement is copyrighted and may
+only be modified in the following manner. The Agreement Steward reserves
+the right to publish new versions (including revisions) of this
+Agreement from time to time. No one other than the Agreement Steward has
+the right to modify this Agreement. The Eclipse Foundation is the
+initial Agreement Steward. The Eclipse Foundation may assign the
+responsibility to serve as the Agreement Steward to a suitable separate
+entity. Each new version of the Agreement will be given a distinguishing
+version number. The Program (including Contributions) may always be
+Distributed subject to the version of the Agreement under which it was
+received. In addition, after a new version of the Agreement is
+published, Contributor may elect to Distribute the Program (including
+its Contributions) under the new version.
+
+Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
+receives no rights or licenses to the intellectual property of any
+Contributor under this Agreement, whether expressly, by implication,
+estoppel or otherwise. All rights in the Program not expressly granted
+under this Agreement are reserved. Nothing in this Agreement is intended
+to be enforceable by any entity that is not a Contributor or Recipient.
+No third-party beneficiary rights are created under this Agreement.
+
+## Exhibit A – Form of Secondary Licenses Notice {#exhibit-a}
+
+“This Source Code may also be made available under the following
+Secondary Licenses when the conditions for such availability set forth
+in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
+version(s), and exceptions or additional permissions here}.”
+
+> Simply including a copy of this Agreement, including this Exhibit A is
+> not sufficient to license the Source Code under Secondary Licenses.
+>
+> If it is not possible or desirable to put the notice in a particular
+> file, then You may include the notice in a location (such as a LICENSE
+> file in a relevant directory) where a recipient would be likely to
+> look for such a notice.
+>
+> You may add additional accurate notices of copyright ownership.
