+## Abschluss, Historie und Lesefreigaben
+
+`src/lib/server/completion.ts` ist die Transaktionsgrenze des endgültigen
+Sendungsabschlusses. Er verlangt einen beendeten Live-Lauf sowie passende Show-
+und Live-Revisionen. Eine Befehls-ID in `show_finalizations` macht Wiederholungen
+idempotent. In derselben Transaktion werden offene Intervalle geschlossen,
+Abschnittskategorien eingefroren, ausschließlich erledigte Verwendungen außerhalb
+der Reservebank in `piece_usage_history` materialisiert, bewusst gewählte
+Fundus-Originale archiviert und die Sendung auf `completed` gesetzt. Jede normale
+Planungs- und Live-Mutation sperrt diesen Zustand.
+
+Die eigentlichen Sendungstexte, Quellen, Werkzeuge, Themen und Medien liegen
+weiterhin in den beim Einplanen erzeugten Usage-Snapshots. Finalisierung friert
+die zuvor noch katalogabhängige Abschnittskategorie ein. Abgeschlossene
+Sendungen werden ausschließlich gelesen oder vollständig in einen neuen Entwurf
+dupliziert. Das Duplikat erhält neue Show-, Abschnitts-, Usage- und Relations-IDs,
+offene Usage-Status und weder Live-, Historien- noch Freigabedaten.
+
+`src/lib/server/shares.ts` erzeugt für Barkeeper zufällige 256-Bit-Lesetokens;
+SQLite speichert nur SHA-256-Hashes. Eine Freigabe verweist direkt auf eine
+Sendung und darf deshalb bereits im Entwurf, im bereiten oder im laufenden
+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
+Gast-Sitzungen. Ablauf und Löschung werden bei jedem HTML-, Seitendaten- und
+Medienrequest erneut geprüft.
+
+Die öffentliche Route `/freigabe/[token]` erhält keine interne Sendungs-ID und
+keinen ungefilterten `Show`-Datensatz. Sie projiziert genau die am Token gebundene
+Sendung und nur die Felder ihres Umfangs. Vor dem Abschluss werden aktuelle
+Sendungs- und Usage-Snapshots bei jedem Aufruf neu gelesen; danach liefert
+dieselbe Projektion die durch die Finalisierung stabilisierten Snapshots. Die
+separate Medienroute akzeptiert ausschließlich das ausdrücklich gewählte
+Präsentationsmedium einer eingeplanten Nicht-Reserve-Verwendung derselben
+Sendung. Private `/media`-Dateien bleiben weiterhin an eine Redaktionssitzung
+gebunden.
+
+Die wiederverwendbare Barkeeper-Komponente `ShareManagement.svelte` liegt direkt
+in der Sendungsbearbeitung und in der Verwaltung. Beide Routen verwenden
+dieselben Servicefunktionen für Anlage, Bearbeitung und Löschung; die
+Sendungsroute bindet Mutationen zusätzlich an ihre eigene Sendungs-ID. Die
+Verwaltung gruppiert bestehende Freigaben nach Sendung und zeigt deren aktuellen
+Status und Termin.

+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.

 # Release Notes
 
+## 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.

+- 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.
