+## Live-Modus und Präsentationsgrenze
+
+`src/lib/server/live.ts` ist die Transaktionsgrenze der Live-Durchführung. Der
+Live-Stand besitzt eine eigene Revision. Jeder steuernde Befehl trägt zusätzlich
+eine vom Browser erzeugte Befehls-ID; `(show_id, command_id)` ist eindeutig und
+liefert bei Wiederholung das bereits gespeicherte Ergebnis. Tatsächliche Zeiten
+liegen als mehrere Start-/Endintervalle je Verwendung vor. Damit bleiben
+Zurückgehen, Wiederaufnahme und bereits abgeschlossene Laufzeit getrennt von der
+geplanten Dauer nachvollziehbar.
+
+Die interne Route `/live` benötigt weiterhin eine aktive Sitzung und darf
+Recherche, Moderation und eigene Arbeitsdaten lesen. Die separate Ausgabe
+`/heinzlive/[token]` liegt dagegen in einem reduzierten Layout ohne Navigation
+oder Nutzerdaten. In SQLite liegt nur der SHA-256-Hash des 256-Bit-Tokens; ein
+neu erzeugter Ausgabezugang widerruft den vorherigen. Page, Polling-JSON und
+Medienroute leiten ihre Daten aus einer eigenen Positivliste ab. Bilder werden
+nur ausgeliefert, wenn sie zum aktuell ausdrücklich präsentierten Piece gehören.
+Normale Auswahl, Fortschaltung oder Wiederaufnahme verändern den
+Präsentationsstand nicht. Die öffentliche Projektion liest ausschließlich den
+gespeicherten Verwendungssnapshot; spätere Änderungen am Original erscheinen
+erst nach einer ausdrücklichen Snapshot-Aktualisierung.
+
+Linkmetadaten werden nur auf ausdrückliche Aktion durch
+`src/lib/server/presentation.ts` geladen. Jeder HTTP(S)-Abruf löst den Zielhost
+serverseitig auf, sperrt lokale und private IPv4-/IPv6-Ziele und bindet den
+Request an die geprüfte Adresse. Dieselbe Prüfung gilt nach höchstens drei
+Redirects. Zeit- und Größenlimits begrenzen HTML, Anbieter-Metadaten und Bilder.
+Externe Vorschaubilder gelangen nur über token- beziehungsweise
+sitzungsgebundene Proxyrouten in die Ausgabe; fremdes HTML und fremde Skripte
+werden nie übernommen.
+
+Videoquellen werden aus der gespeicherten URL erneut auf eine streng validierte
+YouTube- oder TikTok-ID reduziert. Der Browser erhält nur daraus erzeugte
+offizielle Embed-URLs, startet sie nicht automatisch und ersetzt das Iframe bei
+jedem Inhaltswechsel. YouTube erhält die Startsekunde als Embed-Parameter;
+TikTok wird nach dessen Bereitschaft über die offizielle Player-`postMessage`-
+Schnittstelle positioniert. Nicht unterstützte oder unvollständige Videoquellen
+fallen auf eine normale Linkkarte zurück. Eine authentifizierte Testansicht
+verwendet denselben Renderer, schreibt aber keinen Live-Zustand.
+
+Die Ausgabe synchronisiert ihren kleinen öffentlichen Zustand per
+`no-store`-Polling. Der letzte gültige Inhalt bleibt bei einem Verbindungsfehler
+sichtbar; die Oberfläche kennzeichnet den Abbruch und versucht die Verbindung
+mit verlangsamtem Intervall erneut. Private Live-Daten werden nicht Teil dieses

+## D-016: Live-Befehle idempotent, tatsächliche Zeiten als Intervalle
+
+Die Live-Steuerung verwendet eine eigene Revision und zusätzlich eine pro
+Bedienaktion erzeugte Befehls-ID. Die Datenbank akzeptiert jede Kombination aus
+Sendung und Befehls-ID nur einmal. Ein nach Verbindungsabbruch wiederholter
+Befehl liefert dieselbe Ergebnisrevision und erzeugt weder einen zweiten
+Statuswechsel noch ein zweites Zeitintervall. Laufzeit wird nicht als einzelner
+überschreibbarer Wert, sondern als Summe abgeschlossener und höchstens eines
+aktiven Intervalls ermittelt. Dadurch bleiben Zurückgehen und Wiederaufnahme
+korrekt.
+
+## D-017: Präsentationsausgabe als Positivliste mit gehashtem Zugang
+
+Die heinzlive-Ausgabe ist kein eingeschränkter Aufruf der internen Live-Ansicht,
+sondern eine eigene Datenprojektion. Zulässig sind ausschließlich ausdrücklich
+präsentierter Titel und Präsentationstext, öffentliche Quellen sowie zugehörige
+Bilder und Alternativtexte. Recherche, Einleitung, Moderation, eigene Notizen,
+Ablauf, Nutzer und interne Dateinamen werden nicht in HTML oder JSON übernommen.
+Ein zufälliger 256-Bit-Token steht in der URL, während SQLite nur seinen
+SHA-256-Hash speichert. Medienzugriff prüft Token, aktuelle Präsentation und
+Bildzuordnung gemeinsam. Synchronisierung erfolgt über kleines `no-store`-
+Polling statt über eine dauerhaft offene Serververbindung.
+
+## D-018: Verwendung aus bestehenden Sendungsdaten ableiten
+
+„Gesendet“ ist kein Zustand am Fundus-Piece. Die Anzeige wird ausschließlich
+aus der vorhandenen Original-ID, einer erledigten Verwendung außerhalb der
+Reservebank und dem Status `completed` ihrer Sendung abgeleitet. Dadurch können
+Einplanung, Reserve und Überspringen ein Original nicht versehentlich als
+gesendet markieren, und mehrere tatsächliche Verwendungen bleiben als Historie
+sichtbar.
+
+Eine Duplikation im Sendungsablauf kopiert den konkreten Verwendungssnapshot und
+nicht das Original-Piece. Die neue ID, der Status `open` und fehlende
+Live-Intervalle trennen sie von der bisherigen Durchführung. Der allgemeine
+Verwendungseditor darf den Live-Status nicht mehr aus Formulardaten schreiben;
+Statuswechsel bleiben der Live-Geschäftslogik vorbehalten.
+
+Eine bestehende Einplanung wird nicht automatisch mit späteren Änderungen am
+Original synchronisiert. Die ausdrücklich ausgelöste Aktion **Aus Fundus
+aktualisieren** überschreibt nur Titel, Dauer und Redaktionstexte. Eigene
+Notizen, Status und Messintervalle bleiben erhalten. Alle Zuordnungen und Filter
+verwenden ausschließlich `original_piece_id`, niemals veränderliche Titel. Im
+allgemeinen Fundus gilt „eingeplant“ global für jede nicht abgeschlossene
+Sendung; im Sendungsbau gilt es lokal für die aktuelle Sendung samt Reserve.
+
+## D-019: Lokale Linkmetadaten und streng abgeleitete Video-Embeds
+
+Sendewerk verwendet Metascraper ausschließlich serverseitig, um Titel,
+Beschreibung, Bild und Herausgeber einer ausdrücklich gewählten vorhandenen
+Quelle zu ermitteln. Die Ergebnisse werden gespeichert und nicht bei jedem
+Seitenaufruf neu geladen. Manuell korrigierte Felder haben Vorrang. Ein eigener
+HTTP(S)-Client prüft Protokoll, Port, DNS-Ergebnisse und jedes Redirectziel,
+bindet den Request an die geprüfte öffentliche Adresse und begrenzt Redirects,
+Laufzeit und Antwortgröße. Damit ist weder ein externer Vorschaudienst noch die
+Übernahme fremden HTMLs erforderlich.
+
+Player werden nur für streng erkannte YouTube- und TikTok-URLs erzeugt. Aus der
+validierten Anbieter-ID baut Sendewerk die offiziellen Embed-Adressen selbst;
+gespeichertes oder fremd geliefertes Embed-HTML wird nicht verwendet. YouTube
+nutzt die datenschutzreduzierte `youtube-nocookie.com`-Adresse und den
+`start`-Parameter. TikTok erhält eine Startposition nach `onPlayerReady` über
+die dokumentierte Player-`postMessage`-API. Autoplay bleibt ausgeschaltet, und
+ein Inhaltswechsel ersetzt das Iframe vollständig.
