+
+`src/lib/server/completion.ts` ist die Transaktionsgrenze des endgültigen
+Sendungsabschlusses. Er verlangt einen beendeten Live-Lauf sowie passende Show-

+Planungs- und Live-Mutation sperrt diesen Zustand.
+

+weiterhin in den beim Einplanen erzeugten Usage-Snapshots. Finalisierung friert
+die zuvor noch katalogabhängige Abschnittskategorie ein. Abgeschlossene

+Zustand entstehen. Der Umfang ist eine Positivliste aus `rundown`, `moderation`
+oder `research`. Optionale Passwörter liegen als Argon2id-Hash vor. Nach
+erfolgreicher Prüfung entsteht eine höchstens zwölf Stunden gültige, ebenfalls
+nur gehashte Gast-Sitzung; Fehlversuche werden pro Link und Clientadresse
+begrenzt. Änderungen an Umfang, Passwort oder Ablauf invalidieren bestehende

+Medienrequest erneut geprüft.
+
+Die öffentliche Route `/freigabe/[token]` erhält keine interne Sendungs-ID und

+
+Ein beendeter Live-Lauf ist wiederaufnehmbar und deshalb nicht identisch mit

+`shows.status` auf `completed`. Eine dauerhaft gespeicherte Befehls-ID verhindert
+Doppelverbuchung; Usage-Historie enthält nur `done`, nie `skipped` oder Reserve.
+Bestehende Usage-Snapshots bleiben Inhaltsquelle, während Abschnittskategorien
+beim Abschluss zusätzlich eingefroren werden. Historische Sendungen werden nicht
+erneut bearbeitet, sondern mit neuen IDs und zurückgesetztem Laufzustand kopiert.
+
+Lesefreigaben sind keine abgeschwächten Redaktionssitzungen. Sie verwenden eine
+eigene Positivprojektion mit drei kumulativen Umfängen. Roh-Tokens und
+Gast-Sitzungstokens stehen nie in SQLite, optionale Passwörter verwenden Argon2id.
+Passwort, Ablauf und Widerruf werden zentral vor Seite, Seitendaten und Medium
+geprüft. Präsentationsmedien sind an Freigabe, Sendung und Usage-Snapshot
+gebunden; beliebige Fundus-Dateien bleiben ausgeschlossen.
+
+Freigaben verweisen auf `shows` statt ausschließlich auf Finalisierungen. Damit
+kann ein Barkeeper bereits einen Entwurf oder eine laufende Planung teilen. Die
+Gastprojektion liest bei jedem Aufruf die aktuellen Sendungssnapshots; der
+spätere Abschluss stabilisiert genau diese bestehende Datenquelle, ohne Token
+oder URL zu wechseln. Bearbeitungen behalten den Link, invalidieren aber
+vorhandene Passwortsitzungen. Vollständiges Löschen ist der unmittelbare
+Widerruf. Die Sendungsbearbeitung und die zentrale Verwaltung verwenden dieselbe
+Geschäftslogik und bleiben Barkeepern vorbehalten.
+
+## D-028: Additive Wartungsfelder und gemeinsamer Freigabedialog
+
+Vorbereitungsaufwand und Twitch-Tags sind optionale additive Felder. Der neue
+Bildmodus verwendet ein separates boolesches Kennzeichen, damit bestehende
+Tabellen und Daten trotz älterer Modus-Check-Constraints ohne riskanten
+Tabellenumbau erhalten bleiben. Freigabeverwaltung bleibt eine gemeinsame
+Komponente und öffnet in allen drei internen Einstiegen als nativer Dialog.
+
+## D-029: RSS als persistenter Eingang mit begrenztem Abruf
+
+Externe Feeds schreiben nie direkt in den Fundus. Quelle und stabiler
+Eintragsschlüssel werden in einem eigenen Eingang gespeichert; dessen Zustand
+`discarded` oder `imported` wird bei einem erneuten Abruf nicht zurückgesetzt.
+Erst eine bewusste Auswahl erzeugt über `content.ts` ein normales Piece samt
+Originalquelle und gewählten Kategorien. Dadurch bleiben redaktionelle
+Entscheidung, Dublettenschutz und Herkunft nachvollziehbar.
+
+Manueller und geplanter Abruf verwenden denselben Adapter. Wie bei
+Linkmetadaten werden private Ziele, Nichtstandardports und ungeprüfte Redirects
+gesperrt; zusätzlich gelten enge Zeit-, Größen- und Mengenlimits. XML-Entities
+bleiben deaktiviert und fremdes HTML wird nicht gespeichert. Ein Fehler wird am
+betroffenen Feed persistiert und unterbricht keine weiteren fälligen Feeds.
+
+## D-030: Technische Tokens, Scopes und persistente Idempotenz
+
+Externe Assistenz erhält keine simulierte Redaktionssitzung und keine
+Sonderrechte. Eigene zufällige Bearer-Tokens liegen nur gehasht vor, sind sofort
+widerrufbar und erlauben entweder Lesen oder Lesen und Schreiben. REST-Routen
+unter `/api/v1` verwenden die bestehenden Inhalts- und Sendungsdienste, damit
+Validierung, Revisionen und Transaktionen identisch bleiben. Jede erfolgreiche
+Mutation wird mit technischem Akteur, Aktion und Ziel protokolliert.
+
+Neuanlage, Einplanung und Sortierung verlangen einen `Idempotency-Key`.
+Zugang, Schlüssel, Hash des Requestinhalts und vollständige Antwort werden in
+derselben SQLite-Transaktion gespeichert. Eine identische Wiederholung erhält
+dieselbe Antwort; ein veränderter Request mit demselben Schlüssel wird
+abgewiesen. OpenAPI 3.1 beschreibt diese Grenze maschinenlesbar. Ein MCP-Adapter
+oder ein bestimmter KI-Client wird nicht vorgetäuscht: Die Anwendung bleibt ohne
+KI vollständig nutzbar und eine konkrete Client-Verbindung muss separat geprüft
+werden.
+
+## D-031: Usage-basierte Vorbereitung und rotierende Freigabelinks
+
+Die Sendungsübersicht erzeugt keinen zusätzlichen Vorbereitungszustand. Sie
+projiziert konkrete Usage-Snapshots aktiver Sendungen, deren Fundus-Original noch
+`preparing` ist. So bleiben bestehende Daten und Snapshots unverändert, während
+ungeplante Fundus-Arbeit aus der Sendungsübersicht verschwindet.
+
+Weil Freigabetokens nur gehasht gespeichert werden, kann ein bestehender Link
+nicht erneut angezeigt werden. Ein Ersatzlink rotiert deshalb den Token derselben
+Freigabe transaktional und löscht alle Gastsitzungen; Sichtumfang, Passwort und
+Ablauf werden nicht stillschweigend verändert.
+
+## D-032: Vorbereitung als Eigenschaft der konkreten Einplanung
+
+Die erste 0.7.1-Umsetzung aus D-031 leitete den Vorbereitungszustand noch vom
+veränderlichen Fundus-Original ab. Das widerspricht der bestehenden Kopierregel
+für Sendungsfassungen und verhindert unterschiedliche Arbeitsstände bei
+Mehrfachverwendung. D-032 ersetzt deshalb diesen Teil von D-031: Status und
+Aufwand werden mit Migration `0019` additiv an `piece_usages` gespeichert.
+
+Vorbereitende und sendefertige Originale dürfen eingeplant werden. Einplanung,
+Duplikation und ausdrückliches Aktualisieren kopieren den Zustand, während der
+Usage-Editor ihn danach unabhängig ändert. `piece_usages.status` bleibt davon
+getrennt und beschreibt weiterhin ausschließlich den Livezustand `open`,
+`current`, `done` oder `skipped`.
+
+## D-033: Auswahlzustand flüchtig, Verwaltungslogik gemeinsam
+
+Quellenfilter, Pagination und Mehrfachauswahl des RSS-Dialogs bleiben lokaler
+UI-Zustand. Persistiert wird erst durch die bestehende transaktionale
+Importaktion, damit Blättern oder Öffnen eines externen Links niemals
+redaktionelle Inhalte erzeugt. Die Verwaltung ruft weiterhin dieselben Feed-
+und Zugangsdienste auf; neue Dialoge ersetzen nur die dauerhaft ausgebreiteten
+Formulare. Ein technischer Zugang darf Name und Umfang ändern, behält dabei aber
+seinen ausschließlich gehasht gespeicherten Token und erzeugt ein Auditereignis.
+
+Das Live-Menü zeigt einen rein gelesenen Verbindungsstatus des Ausgabekanals.
+Nur die bereits vorhandenen expliziten Verbinden-, Rotieren- und Trennenaktionen
+verändern öffentliche Ausgabe. Navigation zur Planung bleibt davon getrennt.

 # Release Notes
 
+## 0.7.2 - RSS-Auswahl, Live-Menü und Schnittstellenverwaltung
+
+Veröffentlicht am 26. Oktober 2026
+
+- Der Eingang zeigt neue RSS-Beiträge in einer kompakten Katalogfläche. Ein
+  großzügiger, mobil vollflächiger Dialog filtert mehrere Quellen vor der
+  Seiteneinteilung, zeigt 20 Beiträge je Seite und behält die barrierefrei
+  erkennbare Auswahl über Quellen- und Seitenwechsel. Erst die ausdrückliche
+  Übernahme erzeugt Eingangspieces; Herkunft, Kategorien, Verwerfen und
+  Dublettenschutz bleiben erhalten (#16).
+- Das Live-Menü folgt der Nutzerabsicht: Sendungssteuerung, kompakte Ansicht,
+  Lesefreigaben, standardmäßig eingeklappte OBS-Ausgabe und getrennte Navigation
+  sind klar geordnet. Pause/Fortsetzen sowie Abschnitts- und Gesamtreset liegen
+  direkt bei den Timern. Laufend, pausiert und beendet werden eindeutig
+  unterschieden; Navigation allein verändert weder Lauf noch Ausgabe (#18).
+- RSS-Feeds und technische API-Zugänge verwenden Panel, Typografie,
+  Eintragskarten, Classic-Regular-Icons und Dialograhmen des Werkzeugkatalogs.
+  Feeds und Zugänge lassen sich in Dialogen anlegen und bearbeiten; Abruf,
+  Löschen beziehungsweise Widerruf bleiben kompakte Iconaktionen. Neue
+  API-Tokens erscheinen unmittelbar einmalig und kopierbar, während weiterhin
+  nur ihr Hash gespeichert wird (#21).
+- Paket, Lockdatei und Cloudron-Manifest tragen Version `0.7.2`. Es ist keine
+  Datenbankmigration erforderlich. 60 Verhaltenstests und 20 Chromium-Abläufe
+  sind erfolgreich; echte Browser-/Geräteprüfungen außerhalb von Chromium
+  bleiben offen.
+
+## 0.7.1 - Bedienung und Live-Korrekturen
+
+Veröffentlicht am 25. Oktober 2026, Korrekturstand 26. Oktober 2026
+
+- Live-Abschnittszeiten übernehmen geänderte Plandauern. Frühere erledigte oder
+  übersprungene Pieces können offiziell wiederaufgenommen werden, ohne ihre
+  Abschnittslaufzeit oder die Gesamtzeit zurückzusetzen (#1).
+- Mobiler Live-Ablauf, lange Metadaten und Sendungskarten halten ihre verfügbare
+  Breite ein. Der Ablauf bleibt als fokussierbares Sheet bedienbar (#3, #5, #13).
+- „Noch vorzubereiten“ speichert Status und Aufwand an der konkreten Einplanung,
+  priorisiert aktive Sendungen nach Termin und verlinkt mit den Themenicons direkt
+  in den Usage-Editor. Vorbereitende Originale können regulär eingeplant werden;
+  Mehrfachverwendungen bleiben unabhängig (#6, #15).
+- Fundus- und Usage-Editor unterscheiden Text, Nur Bild, Linkvorschau und Video
+  durch kontextsensitive Eingaben und passende Vorschauen (#8).
+- Gast- und historische Abschnitte besitzen klar gepolsterte äußere Glaskarten.
+  Die Freigabeverwaltung liegt direkt vor dem Werkzeugkatalog; der gemeinsame
+  Dialog und seine Formfelder folgen ohne nativen Doppelrahmen dem Sendewerk-
+  Design. Einmalige Links lassen sich kopieren und sicher ersetzen (#11, #12).
+- Die Iconsuche ist nach dem Öffnen sofort sichtbar und fokussiert (#14).
+- RSS-Feeds und technische Zugänge verwenden in der Verwaltung kompakte
+  Hinzufügen-Einstiege und dieselbe visuelle Listenlogik wie der Werkzeugkatalog.
+- Mobiles Live-Sheet und Backdrop sind am Viewport verankert. Viewport-Fit,
+  Standalone-Metadaten und Web-App-Manifest aktivieren iOS-Safe-Areas; ein echter
+  Safari-/Home-Bildschirm-Test bleibt mangels Gerät offen (#3, #13).
+- Paket, Lockdatei und Cloudron-Manifest tragen Version `0.7.1`. Migration
+  `0019_usage_preparation.sql` ergänzt additive Usage-Snapshots. 60
+  Verhaltenstests und 19 Chromium-Abläufe sind
+  erfolgreich; echtes Safari und die installierte Webapp auf iOS bleiben offen.
+
+## 0.7.0 - RSS-Import und externe Assistenz
+
+Veröffentlicht am 25. Oktober 2026
+
+- Barkeeper verwalten RSS-/Atom-Feeds mit Intervall und Standardkategorie;
+  sichere manuelle und geplante Abrufe laufen fehlerisoliert.
+- Neue Beiträge landen in einem getrennten Auswahlbereich im Eingang. Erst eine
+  bewusste Übernahme erzeugt Pieces, während dauerhaftes Verwerfen, Herkunft,
+  Kategorien und Dublettenschutz erhalten bleiben.
+- Abrufe sperren interne Ziele und begrenzen Ports, Redirects, Laufzeit,
+  Antwortgröße und Eintragszahl. Fremdes Feed-HTML wird zu Text bereinigt.
+- Die versionierte REST-API `/api/v1` liest und ändert Pieces, Sendungen und
+  Einplanungen über getrennte technische Lese- oder Schreibzugänge.
+- Technische Tokens werden nur einmal gezeigt und gehasht gespeichert. Widerruf,
+  Audit-Ereignisse, Revisionen und persistente Idempotenz schützen Änderungen.
+- `/api/v1/openapi.json` beschreibt die Schnittstelle für externe Clients.
+  Sendewerk bleibt ohne KI nutzbar; eine konkrete ChatGPT-/Codex-Anbindung ist
+  weiterhin offen.
+- Migration `0018_rss_and_api.sql` ergänzt Feed-, Zugangs-, Audit- und
+  Idempotenzdaten. Paket, Lockdatei und Cloudron-Manifest tragen Version `0.7.0`.
+
+## 0.6.1 - Redaktionelle Wartung
+
+Veröffentlicht am 25. Oktober 2026
+
+- Live-Countdowns übernehmen geänderte Abschnittsplanzeiten, ohne Laufzeit zu verlieren; die mobile Regie gruppiert ihre Kopfaktionen robuster und zeigt den Ablauf als oberstes Sheet.
+- Mobile Formularfelder und die Iconsuche vermeiden iOS-Fokuszoom; Sendungskarten und Gastansicht erhalten klarere Abstände.
+- Pieces führen optionalen Vorbereitungsaufwand, die Sendungsübersicht bündelt offene Vorbereitung und Abschnitte speichern kopierbare Twitch-Tags.
+- Präsentationen können ein ausdrücklich gewähltes Bild ohne Begleittext ausgeben; Originale und Sendungsfassungen bleiben getrennte Snapshots.
+- Lesefreigaben öffnen in Sendung, Verwaltung und Live-Regie über denselben Dialog.
+- Migration `0017_maintenance_fields.sql` ergänzt ausschließlich optionale, rückwärtskompatible Felder.
+
+## 0.6.0 - Abschluss, Archiv und Freigaben
+
+Veröffentlicht am 25. Oktober 2026
+
+Sendewerk 0.6.0 trennt das wiederaufnehmbare Ende eines Live-Laufs vom
+unveränderlichen redaktionellen Abschluss. Abgeschlossene Sendungen erhalten
+eine stabile Historie, liegen im Archiv und können als neuer Entwurf dupliziert
+werden. Barkeeper geben genau eine geplante, laufende oder historische Sendung
+über widerrufbare, optional passwortgeschützte Leselinks frei.
+
+### Abschluss und Historie
+
+- Ein Abschlussdialog zeigt gesendete, übersprungene und offene Pieces getrennt
+  und bietet ausschließlich gesendete Originale zur bewussten Archivierung an.
+- Finalisierung ist transaktional und idempotent. Übersprungene Pieces und die
+  Reservebank werden nicht als gesendet verbucht.
+- Usage-Texte, Relationen, Kategorien und tatsächliche Zeiten bleiben nach dem
+  Abschluss stabil, auch wenn Fundus-Originale oder Kataloge später wechseln.
+- Historische Sendungen sind intern nur lesbar. Die Duplikation erzeugt einen
+  unabhängigen Entwurf mit offenen Pieces und ohne früheren Lauf- oder
+  Freigabezustand.
+
+### Archiv und Freigaben
+
+- Das Archiv zeigt abgeschlossene Sendungen neben archivierten und gelöschten
+  Pieces und bietet die Duplikation direkt an.
+- Barkeeper erstellen Leselinks direkt in der Sendungsbearbeitung oder zentral
+  in der Verwaltung für Ablauf, Moderation oder vollständige Recherche, optional
+  mit Passwort und Ablaufzeit.
+- Noch nicht abgeschlossene Sendungen zeigen Gästen beim nächsten Aufruf den
+  aktuellen Plan. Nach dem Abschluss bleibt derselbe Link auf dem stabilen
+  historischen Stand.
+- Freigaben lassen sich in nach Sendung gruppierten Verwaltungskarten bearbeiten
+  und endgültig löschen; Passwortänderungen beenden vorhandene Gast-Sitzungen.
+- Tokens und Gast-Sitzungen liegen nur gehasht vor; Passwörter verwenden
+  Argon2id und Fehlversuche sind begrenzt.
+- Gastseiten projizieren genau eine Sendung. Private Originaldaten, Nutzer,
+  interne IDs und Felder außerhalb des gewählten Umfangs werden nicht geliefert.
+- Direkte Medienaufrufe prüfen dieselbe Freigabe, Passwortsitzung, Ablaufzeit und
+  den Widerruf erneut und erlauben nur das freigegebene Präsentationsmedium.
+
+### Technik und Prüfung
+
+- Migration `0015_completion_archive_and_shares.sql` übernimmt bestehende
+  abgeschlossene Sendungen und ergänzt Finalisierung, Historie,
+  Duplikationsbefehle, Freigaben, Gast-Sitzungen und
+  Passwortversuchsbegrenzung.
+- Migration `0016_shares_for_active_shows.sql` erhält vorhandene Freigaben und
+  erweitert ihre Referenz auf alle Sendungszustände.
+- Paket, Lockdatei und Cloudron-Manifest tragen gemeinsam Version `0.6.0`.
+- 52 Verhaltenstests und 18 Chromium-Abläufe decken den bisherigen Umfang sowie
+  Abschluss, Archiv und anonyme Lesefreigaben ab.

+Flächen wurden in hellem und dunklem Farbschema kontrolliert. Andere Browser und
+echte Mobilgeräte bleiben offen.
+
+## Fehlerkorrekturen 0.7.1
+
+- Explizite Abschnittsdauern werden während der Live-Regie nach Änderungen
+  synchronisiert. Erledigte oder übersprungene Pieces lassen sich bewusst
+  wiederaufnehmen; frühere Abschnitts- und Gesamtzeiten bleiben dabei erhalten.
+- Der mobile Ablauf liegt innerhalb eines isolierten Live-Containers, lange
+  Metadaten verbreitern die Regie nicht mehr und das Sheet ist am mobilen
+  Viewport verankert. `viewport-fit=cover`, Standalone-Metadaten und Manifest
+  aktivieren Safe Areas auch beim Start vom Home-Bildschirm. Sendungskarten
+  stapeln ihre Inhalte auf kleinen Bildschirmen eindeutig.
+- Die Vorbereitung liegt als eigener Status- und Aufwandsnapshot an der konkreten
+  Einplanung. Vorbereitende Fundus-Pieces lassen sich planen; Originaländerungen,
+  Duplikation und bewusste Aktualisierung folgen der bestehenden Snapshotregel.
+  Usage-Titel, Sendung, Abschnitt, Termin und Themenicons führen direkt in den
+  Usage-Editor; „sendefertig“ entfernt die Fassung aus der Übersicht.
+- Text, Nur Bild, Linkvorschau und Video besitzen in Fundus- und Usage-Editor
+  kontextsensitive Felder und Vorschauen. Ausgeblendete Werte bleiben beim
+  Moduswechsel erhalten.
+- Die Iconsuche fokussiert innerhalb der öffnenden Klick-/Tastaturaktion das
+  Suchfeld. RSS-Feeds und technische Zugänge verwenden gestaltete Formfelder.
+- Lesefreigaben öffnen nach Serverantworten wieder mit dem einmalig sichtbaren
+  Link, bieten Kopieren und sichere Ersatzlinks. Ersatzlinks invalidieren den
+  alten Token und dessen Gastsitzungen. Die Verwaltung zeigt Freigaben direkt
+  vor dem Werkzeugkatalog; der Dialog besitzt nur eine gestaltete Glasfläche.
+  Gast- und historische Abschnitte besitzen äußere Karten mit Innenabstand.
+
+Geprüft wurden 60 von 60 Verhaltenstests, Lint, Typprüfung, Produktionsbuild und
+19 von 19 Chromium-Abläufe. Die Browsermatrix öffnete beide Piece-Editoren,
+Sendungsübersicht, Verwaltung und Freigabedialoge, Gastansicht sowie Live-Regie
+bei Desktop- und Mobilbreiten. Safari und die installierte Webapp auf einem
+echten iOS-Gerät bleiben mangels Gerät getrennt offen.
+
+## RSS-Import und externe Assistenz 0.7.0
+
+- Barkeeper verwalten RSS-/Atom-Feeds mit Standardkategorie, Aktivierung und
+  Abrufintervall; manueller Abruf und ein begrenzter Prozess-Scheduler verwenden
+  dieselbe Fehler- und Dublettenlogik.
+- Feedabrufe prüfen Protokoll, Port, DNS und Redirects, begrenzen Laufzeit,
+  Antwortgröße und Eintragszahl und lassen Fehler anderer Feeds unberührt.
+- Fremdes HTML wird entfernt. Beiträge bleiben mit stabiler Herkunft im
+  getrennten Importeingang, bis die Redaktion sie auswählt, kategorisiert und
+  als normale Pieces übernimmt oder dauerhaft verwirft.
+- `/api/v1` bietet Pieces und Sendungen über gehashte, widerrufbare technische
+  Bearer-Tokens mit reinen Lese- oder Lese-/Schreibrechten an. Mutationen nutzen
+  bestehende Dienste, Audit-Ereignisse, Revisionen und persistente
+  Idempotenzschlüssel.
+- Die maschinenlesbare Beschreibung liegt unter `/api/v1/openapi.json`; eine
+  ChatGPT-/Codex- oder andere konkrete Client-Anbindung wurde nicht eingerichtet.
+- Migration `0018_rss_and_api.sql` ergänzt ausschließlich additive Tabellen und
+  Indizes. Sendewerk bleibt ohne KI und ohne konfigurierte Feeds vollständig
+  nutzbar.
+
+Geprüft wurden 58 Verhaltenstests, Typprüfung, Produktionsbuild, Dependency-
+Audit, vier RSS- und zwei Zugangssicherheitstests sowie ein echter HTTP-Rundlauf
+lesen → anlegen → idempotent wiederholen → ändern → erneut lesen → einplanen →
+sortieren. Desktop-Verwaltung und mobiler Eingang wurden in Chromium ohne
+Konsolenfehler geprüft. In der bestehenden Gesamtmatrix waren 16 von 18 Abläufen
+erfolgreich; die bereits bekannte Live-Zeitanzeige und der Ablauf
+Abschluss/Freigabe schlugen weiterhin fehl. Der globale Lintlauf bleibt an acht
+vorhandenen Formatierungsabweichungen außerhalb dieser Etappe offen.
+
+## Wartungsrelease 0.6.1
+
+- Abschnitts-Countdown, mobile Live-Kopfzeile und Ablauf-Sheet wurden korrigiert; die doppelte Piece-Positionsanzeige entfällt.
+- Optionaler Vorbereitungsaufwand, kompakte Vorbereitungsliste und Abschnitts-Twitch-Tags sind additiv persistiert.
+- Der Präsentationsmodus `image` gibt ausschließlich das bewusst gewählte Snapshot-Medium aus.
+- Mobile Eingaben, Iconsuche, Sendungskarten und Gastabstände wurden angepasst.
+- Lesefreigaben verwenden einen gemeinsamen Dialog und sind auch aus der Live-Regie erreichbar.
+
+Geprüft wurden 52 Verhaltenstests, Typprüfung und Produktionsbuild. Im zweiten
+Chromium-Lauf waren 14 Abläufe erfolgreich; zwei Abläufe schlugen vor dem
+Zeitlimit fehl, zwei weitere wurden nicht mehr ausgeführt. Die vollständige
+Browsermatrix bleibt damit offen.
+
+## Abschluss, Archiv und Freigaben 0.6.0
+
+- das Ende eines Live-Laufs bleibt wiederaufnehmbar; erst der getrennte,
+  idempotente Abschluss friert Sendung, Kategorien, tatsächliche Verwendungen
+  und Zeiten unveränderlich ein
+- der Abschlussdialog zählt gesendete, übersprungene und offene Pieces getrennt
+  und archiviert Fundus-Originale ausschließlich nach bewusster Auswahl
+- die Verwendungshistorie wird beim Abschluss materialisiert; übersprungene
+  Verwendungen und die Reservebank zählen nicht als gesendet
+- abgeschlossene Sendungen liegen getrennt im Archiv, sind intern nur lesbar und
+  lassen sich mit neuen IDs, offenen Verwendungen und ohne Live- oder
+  Freigabezustand in einen neuen Entwurf duplizieren
+- Barkeeper verwalten gehashte Leselinks direkt in der Sendungsbearbeitung und
+  gesammelt in der Verwaltung; Umfang, Passwort und Ablauf lassen sich ändern,
+  Freigaben vollständig löschen
+- Entwürfe, bereite und laufende Sendungen lassen sich bereits freigeben;
+  Planänderungen werden beim nächsten Gastaufruf sichtbar, während der Abschluss
+  denselben Link auf den unveränderlichen historischen Stand festlegt
+- passwortgeschützte Freigaben verwenden kurzlebige, gehashte Gast-Sitzungen und
+  begrenzen Fehlversuche pro Link und Clientadresse
+- Gastseiten liefern genau eine positiv projizierte Sendung ohne interne IDs,
+  Originaldaten oder nicht freigegebene Felder; geschützte Präsentationsmedien
+  prüfen Umfang, Passwortsitzung, Ablauf und Widerruf bei jedem Direktaufruf
+- bestehende abgeschlossene Sendungen werden durch Migration `0015` mit
+  eingefrorener Historie übernommen; Migration `0016` erweitert bestehende
+  Freigaben verlustfrei auf noch nicht abgeschlossene Sendungen
+
+Die lokale Prüfmatrix umfasst 52 Verhaltenstests und 18 Chromium-Abläufe.
+Abschluss, Archiv, historische Nur-Lese-Ansicht, Passwortfreigabe,
+Scope-Begrenzung, direkter Medienzugriff, fremde IDs, Gast-Schreibversuch und
+Widerruf wurden zusätzlich in einem anonymen Browserkontext geprüft. Der
+erweiterte Ablauf prüft außerdem offene Sendungen, aktuelle Planänderungen,
+Bearbeiten und Löschen in beiden Barkeeper-Oberflächen sowie Desktop- und
+Smartphone-Layout.
