+# Agenten-Anweisungen für Enelix-EMS
+
+## Aktueller V4-Fortsetzungseinstieg: 06.10.2026
+
+Neuester Quellstand: Bedienintegration und Zusammenfuehrung sind in
+docs/prognose-bedienintegration.md und im obersten Abschnitt der folgenden
+Uebergabe beschrieben. Daniel hat Commit/Push auf develop und beta ausdruecklich
+freigegeben; dies ist kein Anlagenrollout und keine neue Stellfreigabe.
+
+Die vollstaendige Uebergabe liegt auf **enelix-services / Server 89** unter
+`/srv/agent/repos/Enelix-EMS/docs/NETPLAN_V4_AGENT_HANDOFF.md`.
+Vor Fortsetzung zuerst den neuesten datierten Abschnitt lesen. Die Datei ist
+im integrierten Repository versioniert; alte Serverkopien koennen abweichen.
+
+Letzter hier belegter Anlagenzustand: **06.10.2026, 12:01:11 UTC /
+14:01:11 Europe/Zurich**, aus `/srv/agent/v4-recovery-20261006/finished.json`
+auf **iot-symcon01**. Dies ist keine neue Live-Abnahme:
+V4 und alter Netzfahrplan AUS, Batterie 44234 gestoppt, EV-Auftrag 19651 = 0 W.
+Der unabhaengige SDL-Auftrag blieb unangetastet.
+Rueckmelde-/Cache-/Empfangskorrekturen sind installiert; **offen ist die
+instanzbezogene Batterietimerblockade (LastRun=0)**. Kein nachgewiesenes
+physisches Tracking, kein >90-s-Dauerbetrieb und kein automatischer
+Batterie-Watchdog-Lauf. Alte Installer nicht erneut ausfuehren und keine
+externen Tick-Hooks als Umgehung einsetzen. Zuerst Timerursache beheben und
+automatische Ausfuehrung belegen, danach nur innerhalb gueltiger Freigabe testen.
+
+EV bleibt **161.44 kWh / 39 kW**. Die bestehende befristete Testfreigabe endet
+**07.10.2026, 17:38:07 Europe/Zurich**; diese Notiz erneuert oder verlaengert
+sie nicht. Wegfall des zusaetzlichen +/-5-kW-Limits hebt Geraete-, SOC-,
+Netzgrenzen und die dokumentierten Grenzen der Testanlagen-Ausnahme nicht auf.
+Kein Aktivstart oder Dienstneustart aus der Bitte um Kontext-Sicherung ableiten.
+
+Aeltere V4-Statusangaben und damalige "naechste Schritte" weiter unten sind
+historisch, soweit die neuere Uebergabe sie ersetzt. Sonstige Projekt- und
+Sicherheitsregeln sowie separate Manager-Leistungsverteilungsnotizen bleiben
+unveraendert. Aktuellen Zustand und Freigaben vor operativen Arbeiten erneut
+pruefen. Ein neuer Agent muss diese Quellen lesen; kein automatischer Chattransfer.
+
+## Netzfahrplan V4: zuerst den Gesprächskontext übernehmen
+
+Bei Aufgaben zu Netzfahrplan, Prognosen, V4, Batterieoptimierung oder Lihrenmoos **vor Änderungen** die vollständige Übergabe lesen:
+
+**[`docs/NETPLAN_V4_AGENT_HANDOFF.md`](docs/NETPLAN_V4_AGENT_HANDOFF.md)**
+
+Sie enthält Daniels Anforderungen und Korrekturen, installierte versus nur entwickelte Komponenten, Quellen-/Instanzzuordnung, bekannte behobene Fehler, Grenzen der Testfreigabe und den nächsten konkreten Arbeitsschritt. Die Runtime-Berichte stammen zuletzt vom 03.10.2026; Zeitpunkt und aktuellen Zustand prüfen. Alte Entwicklungsdokumente können noch „nicht installiert“ sagen, obwohl ein jüngerer Installationsbericht den Abschluss belegt.
+
+Kurzstand bei Erstellung dieser Anweisung: Unified RC1 und korrigierter Rückmelde-/begrenzter Testpfad installiert; Versandproblem behoben. Nächste offene Umsetzung sind bestätigte Geräte-Lesezeitpunkte statt pauschaler Verwendung von `VariableUpdated` (`feedback_source_skew`). EV **161.44 kWh / 39 kW**, nicht die zurückgenommenen 160/30. Dauerproduktion ist noch nicht fertig; keine automatische Stellfreigabe.
+
+## Arbeits- und Git-Regeln
+
+- Vor Arbeit Host-`/srv/agent/AGENT_CONTEXT.md`, Branch und Arbeitsverzeichnis prüfen. Servercheckout ist nicht gleich laufendes Symcon-Modulverzeichnis.
+- Neue Entwicklung auf **`develop`**, keine Feature-Branches. Nur eigene/zugehörige Änderungen committen. `develop` darf im vereinbarten Rahmen gepusht werden; `beta` nur gemäss ausdrücklicher Freigabe und nach Tests, `main` nach ausdrücklichem Auftrag/Feldabnahme. Keine Schutzregeln oder fehlende Authentifizierung umgehen.
+- Daniel möchte zusammenhängende produktionsgeeignete Umsetzung, keine weitere Schleife aus Diagnosekategorien, identischen Rückfragen und veralteten Installern. Vorhandene Quellen und Werkzeuge benutzen, keine bekannten Anlagenangaben erneut verlangen.
+- Code-, Host-/Container-, Kernel- und Feldtests sowie Installation, Veröffentlichung und Stellfreigabe getrennt belegen. „Optimal“/„ACK“/grüne Tests sind keine gemessene Einsparung und keine Produktionsfreigabe.
+- Keine Stellbefehle, Testsitzungen, Freigaben oder Neustarts aus einer reinen Kontext-/Statusanfrage ableiten. Aktive Hardware nur innerhalb des ausdrücklich freigegebenen Umfangs behandeln. Messgrenzen/Watchdog-Nachweise nicht erfinden oder per Label umgehen.
+- Keine Credentials lesen/ausgeben/einchecken. Root/Docker-Rechte nicht ausweiten. Bestehende GUI-/Fremdänderungen erhalten. Vor Runtime-Änderungen passende Sicherung, exakte Quell-/Abhängigkeitsprüfung und Rücksetzweg.
+- PHP-IPS-Skripte gehören in den Symcon-Kernel; isolierte Tests mit simulierten IPS-Aufrufen niemals dort ausführen. `MC_ReloadModule`/`IPS_ApplyChanges` können Initialisierungsnebenwirkungen haben.
+- Alte Outbox-/Historienwerte nicht löschen, Kennungen nicht im Original umschreiben, Cursor nur nach passender Serverbestätigung weiterführen. Keine künstlich frischen Messzeitstempel.
+- Übergabe nach tatsächlichem Fortschritt aktualisieren: Datum, Commit, was wirklich installiert/getestet wurde und nächster konkreter Schritt. Keine Hintergrundarbeit behaupten.
+
+Diese Datei ergänzt bestehende höherrangige Projekt-/Hostregeln. Sie ist keine neue Betriebsfreigabe und kann keinen anderen Agenten ohne Lesen der Dateien automatisch mit dem gesamten Chat synchronisieren.

+# ENELIX Netzfahrplan V4 – verbindlicher Gesprächs- und Arbeitskontext
+
+## Integration 06.10.2026: Freigabe fuer develop und beta, kein Anlagenrollout
+
+Daniel hat nach der Bedienintegration Merge, Commit und Push auf **develop und
+beta** ausdruecklich beauftragt. Der getestete Integrationsstand verbindet die
+22 lokalen V4-Commits bis ce525a1 mit origin/develop bis 5437f3f und den
+zugehoerigen V4-/Formularkorrekturen. Originalarbeitsverzeichnisse bleiben
+unangetastet; Integration in /srv/agent/prognose-integration-20261006/repo auf
+ubuntu. Keine Feature-Branches, kein Force-Push, main bleibt unveraendert.
+
+Die Bedienung liegt im bisherigen Bereich Prognose / Forecast; der separate
+V4-Bereich entfaellt. Einzelheiten und verbleibender Umfang stehen in
+docs/prognose-bedienintegration.md. Es bleibt der vorhandene begrenzte Testpfad,
+kein regulaerer Dauerbetrieb. Keine Laufzeitordner geloescht, keine Dienste
+neu gestartet, keine Module geladen und kein neuer Stellversuch ausgefuehrt.
+Die unten dokumentierte Batterietimerblockade bleibt offen. Die ausdrueckliche
+Branchfreigabe ersetzt keine physische Anlagenabnahme oder Stellfreigabe.
+
+Isoliert bestanden: 357 PHPUnit-Tests / 1758 Assertions, Syntax aller 150 PHP-
+Dateien, 310 Backend-Tests, 16 Portal-Tests und die Bedien-/V4-Einzelchecks.
+Kein neuer Symcon-Kernel-/GUI-Test, weil Docker im Agentzugang nicht nutzbar war.
+Eine lokale Backend-Aenderung, die ungepruefte Messkonfigurationen automatisch
+mit accountingEvidenceId versah, wurde nach fehlgeschlagenem Schutztest nicht
+uebernommen; Originalarbeitskopie und laufendes Backend bleiben erhalten.
+
+Commit-Autor ist gemaess bestehender Teamklarstellung dh_Agent <dh@belevo.ch>,
+konfiguriertes Gitea-Konto dh. Die Repository-Abfrage bestaetigte Pushrecht;
+die Profilabfrage war mangels read:user-Scope nicht verfuegbar. Fuer den
+tatsaechlichen Veroeffentlichungsstand die Remote-Refs und den Merge-Commit
+pruefen, nicht historische Ahead-/Behind-Angaben weiter unten verwenden.
+
+## Kontext-Sicherung 06.10.2026: Lesereihenfolge und Quellen
+
+Auf Daniels ausdruecklichen Wunsch wird der Arbeitsstand dauerhaft verlinkt.
+Fuer den Laufzeitstand ist der unmittelbar folgende Abschnitt **06.10.2026,
+12:01 UTC** massgeblich, nicht die aelteren Abschnitte 1, 10, 11 oder 15.
+Insbesondere ist der bestaetigte Geraeteabruf bereits implementiert/installiert;
+der naechste Schritt ist die dort belegte instanzbezogene Batterietimerblockade.
+Der Abschlussnachweis `/srv/agent/v4-recovery-20261006/finished.json` auf
+iot-symcon01 wurde erneut gelesen, aber kein neuer Stellversuch ausgefuehrt.
+
+Git-Nachkontrolle in dieser Kontext-Sicherung: nach erfolgreichem Fetch steht
+das Server-89-develop **22 Commits vor / 3 hinter origin/develop**; Remote-Stand
+bei Fetch `58f91e4`. Kein sicherer Fast-Forward. Bestehende fremde/lokale
+Aenderungen bleiben erhalten; kein Merge, Projekt-Commit oder Projekt-Push.
+Das ist vom anderen Checkout auf ubuntu und dessen separat dokumentierter
+Manager-Leistungsverteilung zu unterscheiden.
+
+Die mitgesendeten Screenshots haben kein bestaetigtes Aufnahmedatum und sind
+historische Anschauung, kein neuer Laufzeitnachweis. Der Aktualisierungsdialog
+ist keine Freigabe, lokale Modulaenderungen zu verwerfen. Es wurden keine
+Module aktualisiert, Dienste neu gestartet oder Anlagenfreigaben veraendert.
+
+## Fortsetzung 06.10.2026, 12:01 UTC: Code installiert, Batterietimer blockieren Live-Abnahme
+
+- Daniel hat nach der ausdruecklichen Rueckfrage den Test ohne zusaetzliches +/-5-kW-Limit bestaetigt. Dynamische Geraetegrenzen (hier bis 39 kW), SOC- und Netzgrenzen bleiben verbindlich. Die urspruengliche Freigabe endet unveraendert am 07.10.2026 um 17:38:07 Europe/Zurich (1791387487). Kein Neustart der 48-h-Frist. Der fehlende unabhaengige Hardware-Watchdog bleibt nur durch die bereits genehmigte Testanlagen-Ausnahme abgedeckt.
+- Zusaetzliche allgemeine Arbeitsfreigabe: Routinemaessige Schreibzugriffe auf Lihrenmoos, tunel100 und Server89 benoetigen keine erneute Rueckfrage. Das hebt Sicherheitsgrenzen, technische Berechtigungen, Git-Regeln und konkrete Anlagenfreigaben nicht auf.
+- Der vorstehend beschriebene Kandidat wurde inzwischen installiert und getestet. Weitere eng begrenzte Korrekturen dieser Fortsetzung: (1) Batteriebefehl meldet den konkreten Ablehnungsgrund; (2) physische Geraeteabfrage aus dem Batterie-Stellmutex getrennt, eigenstaendiger 1-s-Samplingtimer mit nicht wartender Lesesperre; (3) Stellpfad nutzt nur unveraenderten bestaetigten Cache, maximal 2 s alt nach Wand- und monotoner Zeit, mit Konfigurations-/Quellenbindungspruefung; (4) passendes Server-Pending fuehrt auch vor Aktivstart zu 15-s-Retry statt zum Verpassen des fertigen Plans, HTTP-429 behaelt normalen Backoff. Cache-90-s-Grenze und physische Zeitstempel wurden nicht verlaengert oder erfunden.
+- Live-Installationen mit SHA-256-Pruefung und Backups: Fehlerdiagnose 11:31:18 UTC; Sampler 11:38:43 UTC; Empfang um 11:50 UTC. Arbeits- und Sicherungsordner: /srv/agent/v4-recovery-20261006 auf iot-symcon01. Berichte deployed.json, sampler-deployed.json, receiver-deployed.json und test-results.json. Geaenderte Quellen und Tests sind auch im bestehenden develop-Arbeitsverzeichnis auf enelix-services, fremde Aenderungen sind erhalten.
+- Letzter Aktivversuch: 11:50:52 UTC, Session 13395dbe-0dbb-42b8-9063-511bd7166f41. Manager meldete danach controller_command_sent (seq 5, 18693 W); Batterie wurde wegen feedback_confirmed_cache_stale_or_invalid gestoppt. Danach Managerabbruch wegen ungueltiger lokaler Betriebsdaten, controllerStopAccepted=true. Kein belastbarer Nachweis von physischem Tracking oder >90-s-Dauerbetrieb. Ein gesendeter Befehl ist ausdruecklich keine Anlagenabnahme.
+- KONKRETE OFFENE BLOCKADE: Saemtliche Timer der Batterieinstanz 44234 zeigen LastRun=0. Meldezyklus (5000 ms) und neuer Rueckmeldungstimer (1000 ms) sind lange ueberfaellig, Running=false. Manager- und uebrige Anlagentimer laufen. Instanzstatus 102; Instanz und alle Elternobjekte nicht deaktiviert; keine dauerhaft belegten Skriptthreads nachgewiesen. IPS_ApplyChanges(44234) bei bestaetigtem Null-Stopp um 11:57:31 UTC gab TRUE zurueck, hat die Timer aber nicht repariert. Die Ursache ist NICHT geklaert. Auch der Batterie-Watchdog hat bisher keinen automatischen Lauf nachgewiesen. Deshalb kein weiterer Aktivstart und keine Umgehung durch einen externen Tick-Hook.
+- Weitere beobachtete Abbruchbedingung: Durch Reloads/Messluecken fehlte zeitweise laufende Viertelstundenenergie; der Planner verwirft Luecken >120 s weiterhin korrekt. Nach einem Quartalswechsel wurden wieder optimale Plaene empfangen. Zum Schluss meldete der Betriebssender zudem veraltete Verbraucher-Rueckmeldung, passend zum nicht laufenden Batterie-Meldezyklus. Keine Energiestaende, Cursor oder Datenbankwerte wurden in dieser Fortsetzung umgeschrieben.
+- Endzustand 12:01:11 UTC: Schalter 46716=false, alter Netzfahrplan=false, Batterie status=stopped, EV-Sollwert 19651=0 W. SDL-Sollwert war 7600 W aus dem unabhaengigen bestehenden Betrieb und wurde nicht auf null gezwungen. Kein physischer V4-Regelungsnachweis. Verbindlicher Abschlussbericht: /srv/agent/v4-recovery-20261006/finished.json.
+- Alle temporaeren Start-, Deploy- und Diagnosehooks wurden aus 12555.ips.php entfernt. Original aus /srv/agent/12555.ips.php.v4hook-backup wiederhergestellt, SHA-256 c702a4947ae200b23c3eecccabeb843ad6a55e97509292584ca2de779d5e4940. Nur v4viewsRun des urspruenglichen getrennten Beobachters verbleibt. Inhaltsuche in /var/lib/symcon/scripts fand keine Verweise auf die V4-Recovery-/Continuation-Hooks. Keine unbeobachtete Wiederanlaufautomatik hinterlassen.
+- Tests erneut erfolgreich: 96 Regel-/Cache-/Lockpruefungen, 32 Empfangspruefungen, 8 Rueckmeldungs-Empfangspruefungen, 9 Geraeteabrufpruefungen und 1 Test der echten Registermethode mit synthetischen Aktionen, insgesamt 146. Syntaxpruefungen erfolgreich; git diff --check sauber. Das sind automatisierte Tests, kein Hardwareabnahmetest.
+- Git bleibt develop, ahead 22 / behind 1 gegen origin/develop, kein sicherer Fast-Forward. Keine Projekt-Commits, Merges oder Pushes. Konto nicht fuer Schreibaktion verifiziert; weder beta noch main geaendert. Die fehlende Live-Abnahme schliesst eine Beta-Freigabe zusaetzlich aus.
+- Naechster fachlicher Schritt: Instanzbezogene Symcon-Timerblockade beheben, automatische Sampler-/Melde-/Watchdog-Ausfuehrung belegen und erst dann einen kontrollierten Neustart des V4-Tests versuchen. Ein etwa erforderlicher Symcon-Dienstneustart betrifft weitere Anlagenfunktionen und wurde hier NICHT ausgefuehrt. Danach physisches Tracking, Planwechsel >90 s und bestaetigten Null-Stopp nachweisen. Alte Startmarker oder Installationshooks keinesfalls einfach loeschen/reaktivieren.
+
+## Fortsetzung 06.10.2026: gepruefter Kandidat, Live-Eingriff noch gesperrt
+
+- Daniel hat die Fortsetzung und die Aufhebung der 5-kW-Testgrenze beauftragt. Die bestehende 48-h-Frist, SOC-/Netz-/Geraetegrenzen und der bereits bekannte fehlende unabhaengige Hardware-Watchdog bleiben unveraendert.
+- Aktuell auf iot-symcon01 gelesen: Refresh-Deployment 07:43:14 UTC; Full-Power-Deployment 08:46:59 UTC. Diese waren schon vor dieser Fortsetzung installiert. Snapshot 09:30:41 UTC: Schalter AUS, Batterie disabled, Manager stopped_fallback_pending wegen ungueltiger lokaler Betriebsdaten. Keine physische V4-Regelung belegt.
+- Neuer Kandidat korrigiert ignorierte FALSE-Rueckgaben von IPS_RequestAction/RequestAction (Start, Command, Stop und Register), den Vor-I/O-Zeitvergleich beim Batterie-Scharfschalten und den blockierenden HTTP-Refresh im Regel-Tick. Separater Empfangstimer: 10 s Prueftakt, aktiver Abruf fruehestens nach 45 s, Fehler-Retry 15 s; Cache-Lebensdauer und Serverzeit bleiben maximal 90 s.
+- Kandidat liegt auf develop im Arbeitsverzeichnis und isoliert unter /srv/agent/v4-continuation-20261006 auf Lihrenmoos. 87 Regeltest-, 29 Empfangs-, 8 Rueckmeldungspruefungen plus 1 echter Modulmethoden-Test mit synthetischen Aktionen bestanden; 5 geaenderte Live-PHP-Dateien syntaxgeprueft. Keine Hardwaretests daraus ableiten. Testbericht: test-results.json im Stage.
+- Neue Tests decken insbesondere FALSE ohne Exception, Sekundengrenze beim Start, bytegleich behaltenen aktiven Cache, 15-s-Retry, 90-s-Ablauf und zukuenftige Empfangszeit ab. git diff --check erfolgreich.
+- Die automatische Sicherheitspruefung hat die Ausfuehrung von /srv/agent/activate_v4_continuation.py abgelehnt, weil diese Live-Installation und Aktivstart koppelt. Der Benutzer wurde um ausdrueckliche Freigabe fuer Installation und Start ohne 5-kW-Limit bis zum bisherigen Ende (07.10.2026 17:38 Europe/Zurich) gebeten. NICHT ueber andere Werkzeuge umgehen. Die Aktivierung wurde nicht ausgefuehrt; 12555.ips.php ist unveraendert.
+- Achtung: Der bestehende temporaere v4_direct_battery_command_hook.php sendet alle 30 s den letzten Managerbefehl erneut. Das kann den Replay-Schutz ausloesen. Vor freigegebenem Neustart kontrolliert entfernen. Vorbereitete Aktivierung sichert den alten Timer und ersetzt alte Schreib-/Diagnosehooks durch eine einmalige gesicherte Installation, genau einen Startversuch und reine Beobachtung. Sie ist noch nicht ausgefuehrt. Bei Live-Drift abbrechen.
+- Git nach erfolgreichem Fetch: develop ist 22 Commits vor und 1 Commit hinter origin/develop (fremder Commit 37addf4). Fremde Lade-/GUI-Aenderungen sind erhalten. Kein Fast-Forward moeglich; kein Commit, Merge oder Push in dieser Fortsetzung. Kandidatenpatch: /srv/agent/v4-continuation-20261006.patch auf enelix-services.
+- Naechster Schritt erst nach Freigabe: Stage/Live-Hashes und Zustand erneut pruefen, Kandidat installieren, genau einen Startversuch beobachten und dessen echte Batterie-Antwort pruefen. Danach >90 s mit Planwechsel, reale Leistungs-/Netzreaktion und sicheren Nullstell-Stopp nachweisen. Erst anschliessend regulaeren Testlauf belassen und temporaere Hooks entfernen. Kein stabiler Aktivbetrieb zugesichert.
+
+Übergabe erstellt am 04.10.2026 auf ausdrücklichen Wunsch von Daniel Häfliger (BELEVO AG). Sie fasst die Anforderungen, Entscheidungen, Fehlerbehebungen und den zuletzt belegten Stand dieses Gesprächs zusammen. Sie ist **kein wörtliches Chatarchiv, keine neue Stellfreigabe und kein Nachweis der Produktionsreife**.
+
+**Zeitbezug:** Die letzten hier belegten Betriebsberichte stammen vom **03.10.2026, ca. 14:02 Uhr Europe/Zurich**. Am 04.10. wurden für diese Übergabe die genannten Berichte und der Git-Stand erneut gelesen, aber keine neue Anlagenabnahme durchgeführt. Alte Messzahlen deshalb niemals als heutige Live-Werte ausgeben.
+
+**Fortsetzung Prognose am 04.10.2026:** Der aktuelle Runtime-Stand wurde gelesen, ohne die alten Diagnose- oder Installationsschritte zu wiederholen. Der abgeleitete Datensatz `lihrenmoos-physical-published-v2` ist `model_ready` und erfüllt mit mehr als 24 nutzbaren äquivalenten Stunden die Trainingsschwelle. Die V4-Einstellungen stehen seit Revision 2 in `shadow` auf `forecastSource=corrected_profile` und `measurementDataset=lihrenmoos-physical-published-v2`; `liveEnabled` und Stellfreigabe bleiben aus. Der erste echte Lauf zeigte einen kompatibilitätsbedingten Stopp bei mikrosekundengenauen `observedAt`-Zeitstempeln. Die Korrektur rundet ausschliesslich die kausale Verfügbarkeit von Prognoseereignissen auf die nächste volle Sekunde auf; Rohmessungen bleiben streng ganzsekündlich. 310 Python- und 16 Portal-Tests sind erfolgreich. Repository und Runtime-Build-Kontext enthalten bytegleich den geprüften Fix; der laufende Container enthält ihn noch nicht, weil beide Agentzugänge weder Docker-Socket noch `sudo` erhalten. Der vorbereitete, syntaktisch geprüfte Root-Rollout liegt unter `/home/agent/services/netplan-v4-shadow/commissioning/finish_corrected_forecast_rollout.sh` und baut/testet vor dem Austausch, hält das vorige Image als Rollback fest und ändert keine Stellfreigabe. Daniel hat danach einen Aktivbetrieb angefragt; der aktuelle V4-Kern ist jedoch technisch `shadow-only`, und die weiterhin unbelegte Rückmeldung (`feedback_source_skew`, `usableForTrial=false`, `canDispatch=false`) verbietet ein blosses Umstellen. Keine Live-Freigabe wurde erteilt oder eingebaut. Git-Klarstellung durch Daniel: Commit-Autor `dh_Agent <dh@belevo.ch>`, Gitea-Konto `dh`; Commit/Push auf `develop` und `beta` am 04.10.2026 ausdrücklich freigegeben. Der Agentzugang besitzt derzeit keine HTTPS-Schreibanmeldung für `dh`.
+
+**Fortsetzung bestätigte Rückmeldung am 04.10.2026:** Daniels Freigabe des modellierten `virtual_split` gilt für den ausdrücklich begrenzten Feldtest. Die physische Rückmeldung wurde um synchrone, durch den Gerätetreiber bestätigte Lesevorgänge erweitert: M-Bus verwendet `MBUS_UpdateValues`, ModBus Device und ModBus Address verwenden `ModBus_RequestRead`. Nur ein erfolgreicher Geräteaufruf erzeugt `confirmedAt`; `VariableUpdated` bleibt getrennte Herkunftsinformation. Die Regeltest-Gates verlangen `deviceReadConfirmed=true`. Das reproduzierbare inkrementelle Paket liegt auf der Testanlage unter `/srv/agent/netplan-v4-confirmed-feedback-20261004`; 18 Paketprüfsummen, 37 Rückmeldetests, 7 Geräteabruf-Tests und 71 Regeltest-Prüfungen sind erfolgreich. Es ist noch **nicht im IP-Symcon-Kernel installiert**, weil der lokale JSON-RPC-Zugang ohne Anmeldung mit HTTP 401 antwortet. Die Installation selbst lässt alten Netzfahrplan und beide Regeltestfreigaben aus. Ein realer Stellversuch bleibt zusätzlich durch den nicht belegten unabhängigen Geräte-Watchdog und die fehlende Serverfreigabe blockiert; der vorhandene Symcon-`VorgabeTimeout` ist kein unabhängiger Hardware-Nachweis. Auf `enelix-services` und der Testanlage ist kein nutzbarer Git-HTTPS-Credential-Helper hinterlegt; die Prüfung des Tunnel-Servers lief zweimal in eine externe Connector-Freigabezeitüberschreitung. Tokeninhalt wurde weder gelesen noch ausgegeben. Der Commit des Folgepakets ist lokal mit der vereinbarten Identitaet `dh_Agent <dh@belevo.ch>` erstellt. Der atomare Push auf `develop` und `beta` scheiterte ohne Teilaktualisierung, weil fuer `https://dh@git.belevo.ch` kein Passwort/Token bereitstand.
+
+**Fortsetzung Aktivbereitschaft am 04.10.2026:** Die reale Stellkette wurde in den gespeicherten Testanlagen-Settings bis zu den Aktionszielen geprüft. Die ENELIX-Batterieinstanz 44234 schreibt über das Aktionsskript 31800 auf den EV-Sollwerteingang 19651 des Gateways 58448. Dieses Gateway verteilt im Zwei-Sekunden-Takt auf zwei GoodWe-Pfade über reine SetValue-Aktionsskripte und auf drei SolarEdge-Modbus-Adressen. Der ENELIX-`VorgabeTimeout` setzt bei laufendem Symcon nach 30 Sekunden auf 0 W zurück. Weder im Gateway noch in den drei GoodWe-Aktionsskripten wurde jedoch ein vom Symcon-Kernel unabhängiger Geräte-Watchdog gefunden; auch die SolarEdge-Modbus-Konfiguration weist nur Poll-/Write-Parameter, keinen Geräte-Timeout aus. Ein unbeaufsichtigter 1-2-Tage-Stellbetrieb bleibt deshalb gesperrt. Beide lokalen Regeltestfreigaben sind weiterhin aus, es wurde kein Stellbefehl ausgelöst. Der bestätigte Rückmeldeinstaller ist für einen gestoppten Kernel vorbereitet und geprüft, konnte mangels privilegierter `systemctl`-Berechtigung des Connector-Benutzers aber noch nicht ausgeführt werden. Auf `tunel100` ist ein Credential-Helper für das Konto `dh` vorhanden und ein `develop`-Dry-Run war erfolgreich; die danach nötige Connector-Freigabe lief erneut ab, bevor der lokale 19-Commit-Stand übertragen und veröffentlicht werden konnte.
+
+## 1. Zuerst lesen: Wo wir tatsächlich stehen
+
+- Daniel möchte die **fertige, produktionsgeeignete Anwendung**, nicht weitere isolierte Sammler, Diagnosekategorien oder wiederholte Bestätigungsrunden. Er hat die fortlaufende Umsetzung mehrfach beauftragt. Probleme im Code selbst beheben, Tests und Auslieferung bündeln; ihn nur für wirklich notwendige Root-/Symcon-Ausführung oder echte Anlagenfreigaben einbeziehen.
+- Datenaufnahme, bestätigter Versand, historische Aufbereitung, Modellaufbau, V4-Optimierer, Planempfang und ein ausdrücklich begrenzter Regeltest sind implementiert. Der zuletzt installierte Teil verbindet korrigierte physische Rückmeldung mit Vorschau und dem **begrenzten** Test-Stellpfad.
+- Der Versandblocker durch `100.0`/`100` ist **behoben und der Nachversand hat aufgeholt**. Nicht erneut beim Cursor oder der alten Kennungsdiagnose anfangen.
+- Die letzte Feedback-Installation ist **erfolgreich abgeschlossen**, nicht mehr `waiting_for_registration`. Bericht: `corrected_feedback_installed_trial_disabled`, Rückmeldung `unavailable`, Grund **`feedback_source_skew`**.
+- **Nächster konkreter Entwicklungsauftrag:** bestätigte, zum tatsächlich gelesenen Wert passende Geräte-Lesezeitpunkte an den lokalen Rückmeldepfad anschliessen. Bisher wird `VariableUpdated` als Live-Zeitbasis verwendet; unveränderte Modbus-Werte werden aber nicht zwingend bei jedem erfolgreichen Abruf erneut publiziert. Geräteabruf, Variablenpublikation und aktueller Lesezugriff müssen auseinandergehalten werden.
+- Keine künstliche Zeitstempelverjüngung, pauschale Toleranzerhöhung, Nullersetzung, historische Interpolation als Live-Messung oder Rückkehr zum festgehaltenen virtuellen EV-Wert.
+- **Weiterhin keine produktive V4-Batterieausführung:** alter intelligenter Netzfahrplan AUS; beide lokalen Regeltestfreigaben AUS; kein gestarteter Stellversuch. Bestehende lokale Regelung und SDL laufen unabhängig weiter.
+- Ein uneingeschränkter Produktions-Dauerregler ist **noch offene Umsetzung**, nicht nur ein fehlender Haken. Automatik, reale Modellqualität, Geräteausfallverhalten und Mehranlagenfreigabe haben ebenfalls verbleibende Grenzen.
+- Letzter fachlicher EMS-Commit: **`9878197`**, `develop`, bei Übergabeprüfung sauber und **15 Commits vor lokalem `origin/develop`**. Kein Remote-Fetch in dieser Prüfung. Vorherige Pushversuche scheiterten an Authentifizierung. Dokumentations-Commits dieser Übergabe können danach folgen.
+
+## 2. Arbeitsweise und Freigaben
+
+Daniel ist technisch versiert, will aber keine unnötige manuelle Kleinarbeit. Deutsch, Schweizer Schreibweise, konkrete nutzbare Befehle. Ein abgeschlossener Test ist nicht automatisch Installation, Installation nicht Stellfreigabe, `optimal` nicht reale Einsparung. Immer getrennt berichten: implementiert / isoliert getestet / Zielcontainer getestet / installiert / im Kernel geprüft / am Gerät erprobt / veröffentlicht.
+
+**Nicht wieder in die alte Schleife zurückfallen:**
+
+1. Keine neuen Diagnosekategorien als Ersatz für die eigentliche Integration.
+2. Keine erneuten Fragen nach bereits bestätigten EV-Kapazitäten oder pauschal immer wieder nach Wechselrichtertypen. Bestehende Quellen nutzen. Eine tatsächlich fehlende sicherheitsrelevante Eigenschaft darf trotzdem nicht erfunden werden.
+3. Nicht einfach „24 Stunden warten“, solange ein Software- oder Übertragungsfehler das Training verhindert.
+4. Keine alten Einzelinstaller erneut ausführen; neueren Quellstand und parallele GUI-Arbeit nicht überschreiben.
+5. Nicht behaupten, im Hintergrund weiterzuarbeiten. Nur tatsächlich ausgeführte Arbeit und belegte Ergebnisse berichten.
+6. Die Regel „ein einziger konkreter Punkt“ betraf Einträge in **Offene Punkte**, nicht Entwicklungsaufträge. Implementierungsaufträge dürfen zusammenhängende Anforderungen bündeln.
+
+**Git:** Keine Feature-Branches. Entwicklung auf `develop`; nach Tests `beta`; nach Feldtest `main`. Daniel hat im Gespräch Commit/Push für `develop` und damals auch `beta` ausdrücklich freigegeben. Diese Freigabe nicht als Auftrag interpretieren, einen aktuell ungetesteten Kandidaten blind auf `beta`/`main` zu schieben. `develop`-Push ohne erneute Nachfrage im bestehenden Rahmen erlaubt. Nicht force-pushen, nicht unzusammenhängende Änderungen übernehmen, keine Zugangsdaten verlangen/ausgeben. Historische Agenten-Commitidentität war `ENELIX Agent <agent@enelix.invalid>`; keine globale Git-Konfiguration ungeprüft ändern.
+
+Die aktuelle Nachricht beauftragt **Kontextübergabe**. Sie erteilt keine zusätzliche Anlagen-, Runtime- oder Stellfreigabe. Bei späterer Fortsetzung greifen die bestehenden Sicherheits- und Branchregeln weiter.
+
+## 3. Ursprüngliches fachliches Ziel
+
+### 3.1 Prognosefamilien und Erweiterbarkeit
+
+Im GUI manuell eine Familie wählen oder `auto`:
+
+| Familienschlüssel / Fahrplan | PV | Last | Fahrplanvariable |
+|---|---|---|---|
+| `3` | `prog_var_1` | `prog_var_2` | `prog_var_3` |
+| `13` | `prog_var_10` | `prog_var_11` | `prog_var_13` |
+| `23` | `prog_var_21` | `prog_var_22` | `prog_var_23` |
+
+Die neun Zahlen sind nicht neun unabhängige Fahrplanmodelle. Daniel akzeptierte die Auswahl der vollständigen Modellfamilie. Registry und Datenadapter so gestalten, dass weitere Familien und später weitere flexible Anlagen ergänzt werden können. Nicht behaupten, drei bereits vorhandene Lastmethoden seien identisch mit den neu aufgebauten physischen Profilen; Datenquelle und Modellversion müssen sichtbar sein.
+
+`auto` soll jene Familie wählen, die in der jüngeren Vergangenheit **wirtschaftlich am besten abgeschnitten hätte**, mit gleichen Anfangsbedingungen, Tarifen, SOC-/Restenergiebewertung und Randbedingungen. Keine Auswahl allein nach R², keine Zukunftsinformation im historischen Replay. Mindestabdeckung, Mindestdauer, Rückblick und Wechselmarge verhindern häufige/schlecht belegte Wechsel.
+
+### 3.2 Netzfahrplan / Optimierung
+
+- Bis zu **48 Stunden**, grundsätzlich **5-Minuten-Schritte** (höchstens 576), rollende Neuberechnung.
+- Ausgangsverlauf: korrekt abgegrenzte Verbraucherlast minus PV plus separat berücksichtigte externe Flüsse. Darauf flexible Verbraucher optimieren; aktuell EV-Batterie, später Ladestationen, Boiler usw.
+- Batterie: aktueller virtueller EV-SOC, dessen zugehörige EV-Gesamtkapazität, aktuelle maximale Lade-/Entladeleistung, Min-/Max-SOC, Reserve, Hysterese, Verfügbarkeit und lokale Einschränkungen. Keine zukünftige Energie vor dem Laden nutzen.
+- **90 % Roundtrip-Wirkungsgrad**, nicht zweimal 90 %. Implementierung verteilt Verluste mit `sqrt(0.9)` auf Laden/Entladen.
+- Netzladen ist ausdrücklich erlaubt/gewünscht, wenn freigegeben und wirtschaftlich sinnvoll. Nicht generell Nachtbezug verbieten oder tagsüber Entladung verbieten.
+- Kosten pro Intervall: Bezugsenergie mal Bezugspreis minus Einspeiseenergie mal Einspeisepreis. Leistungswerte in W/kW korrekt über Zeit in kWh umrechnen. Gesamtkosten minimieren, nicht mathematisch auf exakt null zwingen; negative Kosten sind möglich, nicht garantiert.
+- Statische oder dynamische, in der Anlage konfigurierte Bezugspreise und Einspeisevergütungen verwenden. GUI-Preisänderungen speichern und Neuberechnung anfordern. PV-Vergütung, Netzladekosten, Verluste und Peakpreis gehören in dieselbe Wirtschaftlichkeitsbetrachtung.
+- Wenn dynamische Preise noch nicht veröffentlicht sind, den **ausführbaren wirtschaftlichen Horizont auf den bekannten Preisbereich begrenzen** (`published_only`); kein frei erfundener Preis für den Rest der 48 h. Volle Prognose und ausführbaren Preishorizont unterscheiden; Ende passend zur vollständigen Abrechnungsviertelstunde.
+- Restenergie am Horizont fair bewerten/absichern, damit die Batterie nicht am Planende oder zu fast wertlosen Mittagstarifen grundlos leerverkauft wird.
+- Bezug/Einspeisung sowie Laden/Entladen nicht als unphysikalische gleichzeitige Arbitrage zulassen.
+- Einspeisebegrenzung, zulässige Abregelung/entgangene Vergütung und lokale harte Netzgrenzen berücksichtigen. Einen unerreichbaren Plan nicht als eingehalten darstellen.
+
+### 3.3 Monatspeak
+
+- Leistungstarif auf den relevanten **15-Minuten-Netzbezug**; persistenter Monatsmaximalwert, nicht momentane Spitzenleistung. Für den laufenden Monat zusätzliche Kosten nur für Erhöhung über den bereits erreichten Peak; Monatswechsel korrekt behandeln.
+- Bereits verstrichene Energie der aktuellen Viertelstunde mitnehmen. Fehlende Messbasis nicht durch eine konfigurierte Grenze ersetzen.
+- Am Monatsanfang nicht künstlich jede Aktivität verhindern: Restmonatsbewertung/empirische Aussicht ist vorgesehen, mit ausgewiesener Unsicherheit. Ein erwarteter künftiger Peak ist **keine bereits bezahlte kostenlose Freigabe**.
+- Anlagen können **keine feste Bezugsgrenze** haben. Falls im Manager statische oder monatliche Peakgrenzen konfiguriert sind, diese zusätzlich respektieren.
+- Tarifeinheiten und tatsächliche Abrechnungsdefinition prüfen; gemessene, geschätzte und nur konfigurierte Peakwerte getrennt kennzeichnen.
+
+### 3.4 Training, Reaktion und Validierung
+
+Tägliches oder wöchentliches Nachtraining nach GUI-Einstellung; Parameter-/Preisänderungen sollen Neuberechnung auslösen. Getrennte versionierte Historien und Modelle, keine alten belasteten Daten als bereinigt umbenennen. Ein Cold-Start-Modell nach Mindestdatenbasis ist noch keine validierte Feldprognose. Vergleich gegen die bisherige Batterie-Betriebsweise, nicht nur gegen „Anlage ohne Batterie“.
+
+## 4. Lihrenmoos: bestätigte Anlage und massgebliche Korrekturen
+
+- Installation: **`e3a08f9e-af12-4695-99bd-8b51c0520021`**.
+- Symcon Manager **`17004`**, ENELIX-Batterieinstanz **`44234`**, virtuelles Asset **`anlage01-virtual-ev`**, bestehendes EV-/SDL-Gateway **`58448`**.
+- **Massgeblich bestätigt: EV-Kapazität `161.44 kWh`, EV-Leistung `39 kW`.** Die vorher genannten `160 kWh`, `30 kW` und „je 10 kW pro WR“ hat Daniel ausdrücklich als Erinnerungskorrektur zurückgenommen. Daraus keine neue Verteilung auf Einzelgeräte ableiten.
+- Virtueller EV-SOC und die EV-Kapazität bilden ein gemeinsames Energiekonto. Keine SOC-/Energie-Resets oder Umrechnung auf 322 kWh. **SDL-Reserve ist bereits ausgegliedert** und darf nicht nochmals von EV abgezogen werden.
+- Vom Nutzer genannte physische Ausstattung: zwei GoodWe à **50 kW AC**, je **156 kWh** Batterie; SolarEdge **10 kW AC / 10 kWh** Batterie. Summe physische Kapazitäten rechnerisch 322 kWh, nicht die EV-Kapazität. AC-Nennleistung ist kein unabhängiger Nachweis jeder aktuell zulässigen Batterie-Ladeleistung.
+- Dach-PV ungefähr **20 kWp Ost + 20 kWp West**.
+- Exakte Gerätetypen/Firmware, jede AC-/DC-Messgrenze und autonomes Verhalten beim Befehlsausfall sind durch diese Nennwerte nicht automatisch bestätigt. Vorhandene Dokumente/Quellen verwenden, statt Angaben zu erfinden oder Daniel wiederholt pauschal zu befragen.
+- Historischer Tarif-Snapshot: Bezug `CKW Dynamisch Home`, statischer Fallbackwert 0.246 CHF/kWh, Einspeisung „Preis selber eingeben“ 0.10 CHF/kWh, Peakparameter 5.0. **Nicht als aktuelle Tarifvorgabe neu setzen**, vor Verwendung aktuelle Konfiguration lesen.
+
+## 5. Bilanzierung und SDL: nicht wieder die alte Fehlerquelle einbauen
+
+Der alte Prognosesender verwendete sinngemäss `PV + Netz − virtuelle EV-Batterieleistung`. Weil nur die virtuelle EV-Batterie in der Topologie stand, konnte **SDL als Hausverbrauch gelernt** werden. Zusätzlich hält das bestehende Gateway unter bestimmten Bedingungen gefilterte virtuelle EV-/SDL-Istleistungen fest und schreibt sie erneut. Neuer Variablenzeitstempel allein machte diese Werte nicht zur frischen physikalischen Messung.
+
+**Neue Grundidee, bei passender elektrischer Messgrenze:**
+
+`Verbraucherlast = Netzbezug + PV-Erzeugung − gesamte physische Batterieladung`
+
+`Grundlast = Verbraucherlast − separat geplante flexible Verbraucher`
+
+Grundlast bedeutet hier zeitabhängiger nicht separat geplanter Verbrauch, **keine Konstante**. Nicht separat geplante Boiler/Wallboxen bleiben vorerst darin. Später beim Übergang zu eigenständiger Planung genau einmal herausrechnen.
+
+**SolarEdge-Sonderfall:** PV-Variable 20335 war bereits aus skaliertem AC-Ausgang plus Batterieleistung berechnet und auf null begrenzt. Neuer Lastadapter `solar_terminal_v1` verwendet den AC-Ausgang aus 37975/41853 direkt und zieht den SolarEdge-Batteriesaldo nicht nochmals ab. Herkunft, Vorzeichen, AC/DC und Null-Clipping beachten. Algebraischer Bilanzschluss allein ist kein unabhängiger Zählernachweis.
+
+SDL wird **nicht vom V4-Flexibilitätsoptimierer gesteuert**. Bekannten externen Fahrplan berücksichtigen; bei unbekanntem Verlauf nicht still null einsetzen. Die vorhandene Schattenplanung kann den aktuellen SDL-Auftrag als ausdrücklich gekennzeichnete Fortschreibung verwenden. Das ist kein veröffentlichter Zukunftsfahrplan. Für Dauerproduktion sind belastbare externe Grenzen/Reservebehandlung und Konfliktauflösung noch zu prüfen. Ein aktueller SDL-Wert null garantiert keine SDL-freie kommende halbe Stunde.
+
+Bestehendes Gateway: `/var/lib/symcon/modules/Symcon_Belevo_Energiemanagement_testing/Bat_EV_SDL_V4/module.php`. Aktionsbrücke historisch `scripts/31800.ips.php`. `State=false` war dort **kein nachgewiesener Nullstell-/Notstopp**. EV-Stopp darf nicht pauschal unabhängige SDL-Aufträge löschen. Virtuelle Energiekonten/Filter nicht ungeprüft umstellen.
+
+## 6. Quellzuordnung für die nächste Arbeit
+
+Werte/Identitäten mit aktueller Quellenkonfiguration abgleichen; Tabelle ist zuletzt geprüfte Zuordnung, keine Erlaubnis, Register umzulegen.
+
+| Grösse | Variable | Ursprung/Umrechnung |
+|---|---:|---|
+| Original-Netzleistung | 40348 | Parent 11490, `Power_8`, kW ×1000 → W, Bezug positiv |
+| Netz-Anzeige | 49301 | Abgeleitet; nicht mit Originalquelle verwechseln |
+| GoodWe 1 PV | 48459 | Parent 19742, `A_3_3_35301`, W |
+| GoodWe 2 PV | 53802 | Parent 57658, `A_3_3_35301`, W |
+| GoodWe 1 Batterie physisch | 47725 | Parent 19742, `A_6_3_35182`, Faktor −1 → Laden positiv |
+| GoodWe 2 Batterie physisch | 35724 | Parent 57658, `A_6_3_35182`, Faktor −1 |
+| SolarEdge Batterie physisch | 21447 | Parent 30789, `Value`, Faktor +1 |
+| SolarEdge abgeleitete PV | 20335 | Parent 36915; nicht unabhängige PV-Messung |
+| SolarEdge AC-Rohwert | 37975 | Parent 35514, `Value`, ReadAddress 40083 |
+| SolarEdge AC-Skalierung | 41853 | Parent 48996, `Value`, ReadAddress 40084 |
+| Virtuelle EV-Istleistung | 52020 | Parent 58448, `Aktuelle_Leistung_EV`; Filterhaltewert möglich |
+| Virtuelle SDL-Istleistung | 25085 | Parent 58448, `Aktuelle_Leistung_SDL` |
+| EV-Auftrag | 19651 | Parent 58448, `Nennleistung_Soll_EV` |
+| SDL-Auftrag | 38943 | Parent 58448, `Nennleistung_Soll_SDL` |
+| Gateway aktiv | 23483 | Parent 58448, `State`; kein Gerätewatchdog-Nachweis |
+| EV-SOC | 32871 | Parent 58448, `SoC_EV` |
+| SDL-SOC | 23879 | Parent 58448, `SDL_Pos` |
+| EV verfügbare Ladeleistung | 50230 | Parent 58448, `P_EV_laden` |
+| EV verfügbare Entladeleistung | 43899 | Parent 58448, `P_EV_entladen` |
+| GoodWe 1 / 2 / SolarEdge SOC | 27361 / 23109 / 51938 | Originalzuordnung siehe Capture-Konfiguration |
+| Wirkenergie Bezug T1 | 59607 | Parent 11490, `Energy_0`, kWh |
+| Wirkenergie Bezug T2 | 26620 | Parent 11490, `Energy_1`; Zählerarchivierung aktiviert |
+
+**Nicht wieder 53476 als nachgewiesenen Bezugszähler verwenden:** Im Gespräch zeigte 53476 / Quelle 32797 (`Energy_6`) einen unplausibel anderen Verlauf gegenüber Netzleistung und T1. Alte Historie 53476 wurde bewusst nicht überschrieben. Archivinstanz 16207. Neuzeitlicher Peak muss aus geeigneter T1/T2-Summe bzw. ausdrücklich zugelassener vollständiger Viertelstundenschätzung stammen.
+
+Poller laut zuletzt gelesenem Snapshot: GoodWe 1 Parent 19742 `60000 ms`, GoodWe 2 Parent 57658 `5000 ms`; SolarEdge Batterie Parent 30789 `2000 ms`, AC Parent 35514 `1000 ms`, Skalierung Parent 48996 `20000 ms`. M-Bus Parent 11490 hatte `Interval=0`, trotzdem laufend frische Originalwerte. Nicht daraus schliessen, die Erfassung sei aus; zusätzliche bestehende Aufrufwege prüfen. Poller nie allein als erfolgreichen Geräteabruf interpretieren.
+
+## 7. Hosts, Code, Dienste und Berechtigungen
+
+### enelix-services / Connector Server_89
+
+- Host `enelix-services`, IPv4 `87.106.60.89`, Agentbenutzer `agent`. Erlaubte Wurzeln `/home/agent/services`, `/srv/agent`.
+- Entwicklung: **`/srv/agent/repos/Enelix-EMS`**, Gitea `ENELIX/Enelix-EMS` auf `git.belevo.ch`. Weiteres Projekt `ENELIX/Enelix-Utils`; historische Referenz `dh/Symcon_Belevo_Energiemanagement_testing`. Andere Hosts/Klone nicht ohne Nachweis gleichsetzen.
+- Versionierter neuer Servercode: **`services/netplan-v4/`** im EMS-Repo.
+- Runtime/Build-Staging: **`/home/agent/services/netplan-v4-shadow`**, SQLite `data/netplan-v4.sqlite`, Compose `compose.yaml`, interner V4-Port 9100.
+- Bisheriger Forecast/API-Dienst: `/home/agent/services/prognosis-manager-enelix2`; Forecast Engine interner Port 9000. Nicht durch neue V4-Arbeit unbemerkt ersetzen.
+- Portal: `/home/agent/services/license`, `server.mjs`, `public/`, `compose.yaml`. Parallele GUI-Arbeit möglich. Unified-RC1 aktualisierte nur V4 und zugehöriges Planner-JS, nicht pauschal alle Portalprozesse.
+- Vor Veränderungen `/srv/agent/AGENT_CONTEXT.md` lesen. Agent hatte zuletzt keinen Docker-Socket-/Root-Zugriff; den Nutzer Root-Ausführung nur für tatsächlich benötigte Deployment-Schritte erledigen lassen. Keine Berechtigungen auf Docker-Socket ausweiten.
+
+### iot-symcon01 / Connector Testanlage_Lihrenmoos
+
+- IP-Symcon 8.0, Dienst `symcon.service`, Kerneldateien `/var/lib/symcon`, Logs `/var/log/symcon`, Programme `/usr/share/symcon`.
+- Installiertes EMS-Repo: `/var/lib/symcon/modules/Enelix-EMS`. Das ist produktionsnah laufender Code, nicht der Entwicklungscheckout auf Server_89.
+- Staging, Tests, Diagnose: `/srv/agent/netplan-v4-...`.
+- Hostregeln `/srv/agent/AGENT_CONTEXT.md` lesen. Keine allgemeinen Settings-/Credential-Exports. Für gezielte schreibgeschützte Zustandsprüfung nur erlaubte Felder extrahieren, niemals ganze secret-bearing Konfiguration ausgeben.
+- **PHP mit IPS-Funktionen gehört in Symcon**, nicht in die Linux-Bash und nicht in gewöhnliches CLI-PHP. Isolierte CLI-Tests mit simulierten IPS-Funktionen umgekehrt niemals im echten Kernel ausführen.
+- `MC_ReloadModule`/`IPS_ApplyChanges` können bestehende Initialisierungen und deren Nebenwirkungen ausführen. Nicht pauschal als ohne Auswirkungen versprechen. Code- und Settings-Sicherung, Hash-/Driftprüfung, Rücksetzweg nötig.
+- Bei verzögerter Modulregistrierung wurde ein Wiederholen angefordert. Die letzte Installation ist inzwischen fertig: **jetzt nicht wiederholen**.
+
+## 8. Installierter Daten-/Prognosepfad
+
+1. Manager erfasst 23 numerische Quellen alle 30 s, mit originalen Zeitstempeln und Qualitätsmerkmalen. Keine zusätzlichen Modbus-Abfragen durch den bisherigen Sammler.
+2. Lokale append-only Tagesdateien/Outbox. Versand regulär höchstens einmal/min, bis 120 Aufnahmen pro Batch; geordneter, bestätigter Cursor. Backoff bei Fehlern; Originale bleiben erhalten. `scheduled` kann reguläre Sendepause oder Backoff bedeuten; getrennte letzte erfolgreiche Bestätigung beachten.
+3. Server-Datensatz **`lihrenmoos-physical-v1`** speichert Originalaufnahmen. Abgeleiteter Datensatz **`lihrenmoos-physical-published-v2`** referenziert dieselben Daten für die verbesserte historische Zeitbehandlung.
+4. `equal_endpoint_v1`: begrenzte rückblickende Schätzung bei gleichen Werten an getrennten Originalzeitpunkten. Verfügbarkeit der späteren Bestätigung wird mitgeführt; keine Leckage in damalige Entscheidungen. Unterschiedliche Werte, lange Ausfälle, widersprüchliche Quellen oder Sammellücken nicht unbemerkt überbrücken. Live-Grenzen unverändert.
+5. Worker verarbeitet im 5-Minuten-Takt. Mindestbasis 24 **verwertbare äquivalente Stunden**, nicht bloss seit Start verstrichene Zeit. Neue Tagesprofile, versionierte Modelle, konfigurierbare tägliche/wöchentliche Neubildung. Kaltstart/Validierung sind getrennt.
+6. Neue Datenquelle muss als `corrected_profile` mit passendem `measurementDataset` gewählt werden, sobald verwendbar; zuletzt blieb **`forecastSource=legacy`, `family=3`**. Nicht bei Installation automatisch umgeschaltet. `optimal` auf der Legacy-Quelle ist kein Nachweis der neuen Prognosequalität.
+7. Wirtschaftlicher Vergleich Unified-RC1 ist angeschlossen, aber v1 ist **eingefrorener Tagesplan + simulierte lokale Netzzielnachführung**, nicht vollständiges rollendes MPC-Replay. Eine netzladefähige Batterie; gleiche Anfangsbedingungen, Restenergie, Verluste und einmalige Monatspeakabrechnung. Historischer SDL-Auftrag als gekennzeichnete Schätzung. Vollständige Modellautomatik/Produktversprechen nicht über diesen Scope hinaus behaupten.
+8. Archivierung ist implementiert, **AUS als Standard** (native `NetzfahrplanV4ArchivAktiv`, serverseitig `NETPLAN_V4_ARCHIVE_ENABLED`). Verifizierte komprimierte Archive ersetzen kein externes Backup und lösen keine unendliche Speicherkapazität. Keine unbestätigten Outbox-Daten löschen.
+
+## 9. Behobene Fehler – nicht erneut aufrollen
+
+- Früherer numpy-Fehler `assignment destination is read-only`, falscher Import `battery_optimizer_new`, Dateirechte im unprivilegierten Container: damalige Deployment-/Codefehler, nicht aktuelle Blocker.
+- Direkt nach Start `Connection refused`, danach HTTP 409 „bereits ein Lauf aktiv“: Start-/Parallelitätszustand, nicht durch wiederholte Neustarts lösen.
+- Native Betriebsdaten fehlten; anschließend Sender installiert. Tarifimporter und Portal-Rate-Limit wurden repariert. Alte 429-Meldungen nicht ohne neue Evidenz zur heutigen Ursache erklären.
+- Klasse `NetzfahrplanV4Messaufnahme` doppelt aus Staging und Modulpfad geladen: Installer auf eindeutige installierte Bibliothek umgestellt. `require_once` verhindert nicht verschiedene Dateien mit derselben Klasse.
+- Gemischter 120er-Block: 45 importierte/75 native Aufnahmen, keine doppelten/rückwärtslaufenden Zeiten, aber andere Kennung allein durch `splitToleranceW:100.0` vs `100`. Normalisierung korrigiert; beide vollständigen Konfigurationen exakt geprüft. Kompatibilität nur für diese anlagen- und datensatzgebundene Gleichwertigkeit registriert; Ursprungskennung/Evidence gespeichert. Keine Hashs in Originaljournalen ersetzt, kein Cursor-Sprung.
+- **Nachweis der Reparatur:** am 03.10. 12:58 Schweizer Zeit 1'782 statt 1'320 Aufnahmen, jüngste Aufnahme 12:58:09, 25 s alt, vollständiger ehemals blockierter Batch vorhanden, Manager `acknowledged`/Fehlerzahl 0. Quelle `[F]` unten. Keine Garantie über den danach liegenden Zeitraum ableiten.
+- Historische Datenqualität verbesserte sich von 0 brauchbaren Fenstern auf 104/8.66 h, nach Nachversand 130/10.82 h; zuletzt Worker 140/11.65 h. Prozentangaben zur zeitlichen Abdeckung sind **keine Messgenauigkeit und keine Prognosegüte**.
+
+## 10. Installierter Rückmelde- und begrenzter Stellpfad
+
+Gemeinsamer Code: `NetzfahrplanV4Rueckmeldung.php`, `BatterieNetzfahrplanV4RueckmeldungTrait.php`, `ManagerNetzfahrplanV4EmpfangTrait.php`, `ManagerNetzfahrplanV4TestTrait.php`, `BatterieNetzfahrplanV4TestTrait.php`, `NetzfahrplanV4Regeltest.php`, Manager-/Batterie-Module.
+
+- Zweifaches Lesen mit Identitäts- und Originalzeitprüfung; momentan Live-Alter maximal 60 s, Quellenversatz maximal 30 s.
+- Modus in Lihrenmoos **`virtual_split`**, **`allowEstimatedForTrial=false`**. Auch gültige Rückmeldung oder Vorschau erteilt keine Freigabe.
+- Wenn SDL-Auftrag exakt null, physische Batteriesumme statt gefilterter virtueller EV-Anzeige verwenden; unveränderter Nullauftrag ist Zustand, kein Messgeräte-Heartbeat. Eine neue EV-Vorgabe bedeutet noch keine sofortige physische Reaktion.
+- Bei SDL ungleich null: zeitliche Abdeckung von Auftragsänderung, Tracking-Toleranz und explizite Schätzkennzeichnung. Gegenläufige EV-/SDL-Flüsse sind nicht eindeutig identifizierbar und bleiben für diesen Test gesperrt.
+- Netzziel wird in **Gesamt-Batterieleistung**, nicht zusätzlichen Ladeauftrag übersetzt. Erwartete Änderungen anderer Verbraucher genau einmal berücksichtigen.
+- Separate interne Server-Testsitzung, leere Default-Allowlist `NETPLAN_V4_CONTROL_TRIAL_PLANTS`, manuelle Familie, Anlagen-/Asset-/Instanz-/Revisionsbindung, beide lokalen Freigaben `NetzfahrplanV4RegeltestErlaubt`, bewusster lokaler Start, gültiger Plan, Bilanz- und Gerätewatchdog-Nachweis.
+- Test max. 30 min / 5 kW je Richtung; Serverauthority maximal 90 s; Batteriebefehl maximal 10 s; Batterie-Softwarewatchdog 1 s, Manager-Testtakt 2 s. Nicht einfach Limits für Produktion hochsetzen.
+- Batterie liest vor Ausgabe unabhängig neu und prüft SOC, Reserve, Hysterese, Verfügbarkeit, Sperrzeiten und Netzgrenzen. Unmögliches Netzziel → Testabbruch, keine Erfolgsbehauptung.
+- Abbruch widerruft Sitzung vor Nullstellversuch; Stoppfehler bleibt sichtbar. Danach maximal eine **frisch berechnete** normale Zuteilung, keine Rückkehr zu gecachtem Test-/Vor-Testwert. Keine Wiederbelebung nach Neustart oder doppeltem Befehl.
+- `shadow_seen` bedeutet Empfang, **nicht ausgeführt**. `canDispatch=false` in Vorschau bedeutet keine Vorschau-Freigabe. Bei einer separat gestarteten Testsitzung wäre `runMode=shadow` alleine trotzdem kein hinreichender Nachweis für null Stellbefehle.
+- Softwarewatchdog funktioniert nur bei laufendem Kernel/Kommunikation. Kein Nachweis für Rechnerabsturz, Stromausfall oder unerreichbaren Wechselrichter. Bereits vorhandenes Verhalten prüfen, nicht erfinden und nicht Schutzgates entfernen.
+
+## 11. Aktueller Blocker: bestätigter Geräteabruf statt falscher Zeitbasis
+
+Letzter Installationsbericht `[A]`:
+
+```
+status: corrected_feedback_installed_trial_disabled
+feedback.status: unavailable
+feedback.reason: feedback_source_skew
+batteryW: null
+gridW: null
+usableForTrial: false
+canDispatch: false
+```
+
+Das ist **kein Installationsfehler**. Die Meldung „Modellanteil: nein“ im Installer ist im Fehlerfall irreführend: fehlendes Feld wird als false dargestellt, obwohl die Berechnung gar nicht erfolgreich war. Kleine UI-/Diagnosekorrektur mitnehmen.
+
+Letzte Zeituntersuchung `[B]` (237 Aufnahmen / 2 h): 48 Aufnahmen mit Versatz >30 s. Netz median 1 s/max 2 s, GoodWe 1 median 1 s/max 48 s, GoodWe 2 median 1 s/max 46 s, SolarEdge median 12 s/max 59 s; SolarEdge in 223 Aufnahmen unter den ältesten Quellen. Keine der vier Quellen in genau diesem Zeitfenster über 60 s. Beispiel 13:58:38: drei Quellen neu, SolarEdge 31 s alt → Ablehnung. Frühere mehrminütige Lücken trotzdem nicht damit wegargumentieren.
+
+**Nächste Umsetzung, ohne neue Diagnosekategorie:**
+
+1. Installierten Gerätemodultyp und unterstützten Leseweg verifizieren. Im Gespräch wurde `ModBus_RequestRead()` als möglicher Ansatz genannt. API-/Erfolgs-/Zeitsemantik und Unterschied `ModBus Address` vs `ModBus Device` anhand offizieller aktueller Dokumentation und vorhandenem Code prüfen; nicht voraussetzen, dass ein boolescher Erfolg alle Register atomar aktualisiert oder einen unabhängigen Gerätezeitpunkt liefert.
+2. Erfolgreiche vollständige Antwort mit genau den daraus stammenden Werten, Zuordnung, Status und Bestätigungszeit binden. `VariableUpdated`, Geräteabrufbestätigung und Sammlerzeit getrennt erhalten.
+3. Begrenzte Abfragefrequenz, Timeout, Serialisierung, Kommunikationslast und Lesekohärenz berücksichtigen. Keine Netz-I/O in jedem Vorschau-/Regelcallback vervielfachen, keine blockierenden Abfragen unter dem Stellregler-Lock. Existierende erfolgreiche Polls nach Möglichkeit nutzen.
+4. Wenn keine echte Bestätigung vorliegt, unsicher/gesperrt bleiben. Keine künstlichen `SetValue`-Herzschläge und keine permissive Freigabe bloss wegen des Pollerintervalls.
+5. In bestehenden Batterie-/Managerpfad integrieren; Tests: unveränderte Werte mit erfolgreichem Abruf, fehlgeschlagene/partielle Antwort, Zeitversatz, Race, Wiederholung, Neustart, erneute unabhängige Batterieprüfung und Rückfall.
+6. Zusammenhängenden Kandidaten bauen und testen; neue Runtime-Installation nur im bekannten gesicherten Verfahren. Bisherige Installer nicht nochmals ausführen.
+
+Diese Arbeit wurde am Gesprächsende **noch nicht implementiert oder installiert**. Sie ist nicht durch die vorliegende Dokumentationsübergabe erledigt.
+
+## 12. Produktionsreife: verbleibende echte Arbeiten
+
+- Verlässlicher bestätigter Live-Messpfad wie oben; unklares AC/DC/externes SDL nicht durch Labels als verifiziert deklarieren.
+- Neue Lastprofile mit tatsächlicher ausreichender Datenbasis/Validierung aufbauen und gezielt zur Schattenrechnung schalten. Aktuelle Einstellungen/Modelle vorher lesen, nicht alte Momentaufnahmen fortschreiben.
+- **Dauerbetrieb** mit sauberem Authority-/Zustands-/Neustart-/Fallback-Verhalten implementieren. Bisher nur begrenzter Pilot, keine fertige kontinuierliche Produktionsfreigabe.
+- Reale Callback-/Registerstrecke und separat freigegebener Stellversuch; korrekte Vorzeichen, verfügbare Leistungen, Netzziel/Peak-/Exportgrenzen, Abschalten/Verbindungsausfall, lokale Priorität und SDL-Konflikte prüfen.
+- Modellautomatik über den deklarierten Frozen-Day-v1-Scope hinaus nur nach Erweiterung/Nachweis bewerben; Grenzen transparent halten.
+- Lebenszyklus/Backups/Recovery/Observability, Mehranlagenisolierung und parametrisierte Inbetriebnahme. Einige Installer sind bewusst auf Lihrenmoos gebunden; für andere Anlagen nicht IDs blind übernehmen.
+- Git-Authentifizierung/Veröffentlichung lösen; `develop` → geprüfte `beta` → Feldabnahme `main`. Browser-Login, Tailscale oder Portforwarding stellen nicht automatisch Git-Schreibauthentifizierung bereit. Keine Veröffentlichung behaupten, die nicht passiert ist.

+
+1. Host-`AGENT_CONTEXT.md`, Repo-`AGENTS.md` und diese Datei vollständig lesen; bei fehlendem Remote-Stand zuerst den Servercheckout prüfen.
+2. `git status`/Branch/letzte Commits sowie `[A]`, `[B]`, `[C]` lesen. Zeitstempel nennen; keine alten Zähler als heutige Werte ausgeben. Diese Übernahme selbst ändert keine Anlage.
+3. Nur notwendige gezielte Read-only-Prüfungen. Kein weiterer vollständiger Neustart der Analyse oder Wiederholung bereits erledigter Installer.
+4. Bei Fortsetzungsauftrag direkt Abschnitt 11 umsetzen und anschliessend echte Restarbeiten aus Abschnitt 12 abarbeiten. Anforderungen, Testfall, Implementierung und Rollout in einem Paket halten.
+5. Nach jedem Abschluss diese Übergabe mit Datum, Codecommit, tatsächlichem Installations-/Teststatus und nächstem konkreten Arbeitsschritt ergänzen. Keine gescheiterten Schritte in „fertig“ umdeuten. Bei Widerspruch aktuelle geprüfte Laufzeit und ausdrückliche spätere Nutzerkorrektur nennen.
+
+**Kurzübernahme:** „Netzfahrplan V4 in ENELIX fortsetzen. Datenkennung/Versand repariert, Unified RC1 und korrigierter Feedback-/Testpfad installiert. Aktuell `feedback_source_skew`; bestätigte Geräte-Lesezeitpunkte in die bestehende lokale Rückmeldung integrieren. EV 161.44 kWh/39 kW. Keine neue Diagnosekategorie, keine alten Installer, kein automatischer Stelltest. Dauerproduktion ist noch nicht fertig; Tests/Abnahme/Veröffentlichung sauber getrennt halten.“

+# V4: getrennte Last-/Batterie-/SDL-Bilanz (Kandidat, keine Stellfreigabe)
+
+## Status 2026-10-02
+
+`NetzfahrplanV4Bilanzierung` ist ein reiner Rechen-/Validierungsbaustein. Noch keine
+Einbindung in die laufende Telemetrie, den Trainer oder den Kontrolltest. Er ruft
+keine IPS-, Netzwerk-, Archiv- oder Stellfunktionen auf. Ergebnis ist immer
+`controlEligible=false`, auch bei geschlossener mathematischer Bilanz.
+
+34 isolierte PHP-Pruefungen wurden mit der gleichen SHA256-Datei auf iot-symcon01
+bestanden. Das ist kein Nachweis fuer die reale Hardware-/Messgrenzenzuordnung
+und kein vollstaendiger PHPUnit- oder Symcon-Kernel-Test.
+
+## Gefundener Unterschied in Lihrenmoos
+
+Installierter Manager `Manager/module.php::leseMessleistungen()` verwendet:
+
+    Haus = PV + Netz - Summe der konfigurierten Batterie-Istleistungen
+
+Konfiguriert ist hier die virtuelle EV-Leistung 52020, nicht die gesamte physische
+Batterieleistung. Daher bleibt der externe SDL-Anteil und eine allfaellige
+Abweichung der virtuellen Aufteilung im an den Prognosedienst gesendeten Hauswert.
+`sendePrognoseTelemetrie()` sendet genau diesen errechneten Wert. Die parallel
+existierenden Hausvariablen 46714 und 40713 sind NICHT automatisch diese Quelle.
+
+Der bisherige Gateway `Bat_EV_SDL_V4` liest die physische Batterieleistung aus
+47725, 35724 und 36380 und invertiert diese Vorzeichen. EV und SDL sind daraus
+abgeleitete, separat gefilterte virtuelle Konten, keine zwei unabhaengigen Zaehler.
+Die Filter koennen alte Teilwerte halten. `UpdateActualPowerSplit` aktualisiert die
+Ausgabevariablen trotzdem. Ein neuer Ausgabezeitstempel beweist deshalb nicht die
+Frische aller darunter liegenden Originalmessungen.
+
+## Kandidat fuer die korrekte Bilanz
+
+Mit einheitlicher Messgrenze und Vorzeichen Batterie+ = Laden, Netz+ = Bezug:
+
+    Verbraucherlast = Netz + PV - gesamte physische Batterieleistung
+    Grundlast = Verbraucherlast - separat geplante flexible Verbraucher
+    Zuordnungsrest = physische Batterie - virtuell steuerbare Batterie - externe virtuelle Konten
+    Externer Netzeffekt = externe virtuelle Konten + Zuordnungsrest
+    Netz = Grundlast + flexible Last + steuerbare Batterie + externer Netzeffekt - PV
+
+Der Zuordnungsrest wird nicht erneut als Hausverbrauch trainiert, sondern separat
+angezeigt. Eine grosse Abweichung sperrt die Datenqualitaet. Gegenlaeufige virtuelle
+Konten (z.B. EV +42 kW, SDL -40 kW, physisch +2 kW) bleiben korrekt getrennt.
+Spaetere Ladestationen/Boiler sind ueber `flexible_load` erweiterbar. Solange sie
+nicht separat geplant werden, verbleiben sie in der nicht separat steuerbaren Last.
+
+Keine Messgroesse wird doppelt subtrahiert. Ein negatives Grundlastergebnis wird
+nicht heimlich auf null begrenzt. Numerische Nullen sind echte Werte; fehlende,
+nicht endliche oder umtypisierte Werte sind keine Nullen.
+
+## Originalzeit und Datenqualitaet
+
+Jede Quelle hat explizite Variable/Parent/Ident, Faktor, maximales Alter und optionale
+Ursprungsabhaengigkeiten. Alle Quellen werden zweimal gelesen. Wertewechsel waehrend
+der Aufnahme werden abgewiesen; Zeitstempel werden nie kuenstlich verjuengt.
+Abhaengigkeiten sind zyklenfrei, doppelte Quellen werden verhindert.
+Eine virtuelle Summenvariable erbt das aelteste Datum ihrer physischen Eingangsquellen.
+Konfigurierbare Alters-/Synchronitaetspruefung ist erforderlich. Diagnoseberechnungen
+mit ungeeigneten Daten bleiben `quality_hold`, nicht `base_load`-Trainingsfreigabe.
+Die momentanen Beispielgrenzen (60 s Alter, 30 s Versatz) sind konservative
+Diagnoseparameter, keine garantierten Geraeteeigenschaften.
+
+Die konkrete Solar-PV-Herkunft sowie AC/DC-/Wirkungsgradgrenzen aller Hybridgeraete
+sind noch zu verifizieren. Eine algebraisch geschlossene Gleichung beweist diese
+physische Messgrenze NICHT. Die vorgeschlagene Quellkonfiguration ist nicht freigegeben.
+
+## Migration in die Prognose (noch offen)
+
+1. Originalmessquellen und Messgrenze dokumentieren und Qualitaet ueberwachen.
+2. Korrigierte Grundlast und externe Kanaele als NEUE versionierte Zeitreihen erfassen.
+3. Bestehende Historien nicht ueberschreiben oder als bereinigte Historie umbenennen.
+   Rekonstruktion nur bei ausreichenden zeitlich passenden Originaldaten.
+4. Prognosemodell auf der korrigierten Basis trainieren/validieren.
+5. Zukunfts-SDL separat liefern. Unbekannt ist nicht null; eine geschaetzte Annahme
+   muss explizit bezeichnet werden und darf nicht als veroeffentlichter SDL-Fahrplan gelten.
+6. Erst nach diesen Pruefungen eine echte Bilanzierungsreferenz im Trial-Gate verwenden.
+   `mappingId` aus dieser Klasse ist ein Konfigurationsfingerabdruck, KEIN solcher Nachweis.
+
+## Gateway-Ausfallverhalten (nicht getestet/freigegeben)
+
+Quelltextpruefung des installierten Alt-Gateways ergab keinen Frischetest fuer
+`Nennleistung_Soll_EV` im Weg `Update -> ApplySetpoints`. Der zwischengespeicherte
+EV-Sollwert wird weiter verwendet, solange die Gateway-Schleife laeuft. Der Eingang
+wird von `scripts/31800.ips.php` geschrieben; dieser enthaelt ebenfalls keine Lease.
+Der vorhandene 30-s-Timeout des EMS-Batterieadapters ist ein Schutz innerhalb von
+Symcon, nicht ein unabhaengiger Wechselrichter-Timeout bei Rechnerausfall.
+
+`State=false` im Alt-Gateway beendet `Update` ohne dort Nullwerte zu schreiben.
+Diesen Schalter nicht als nachgewiesenen Hardware-Notstopp verwenden.
+Keine Kommunikationsunterbrechung, kein Abschalttest und keine neue Stellwertausgabe
+wurden an der realen Anlage durchgefuehrt. Auch aus dem fehlenden Code kann NICHT
+gefolgert werden, dass das Geraet selbst keinen Timeout hat. Exakte Typen/Firmware
+und das wirksame geraeteseitige Verhalten muessen noch festgestellt werden.
+
+Wichtig fuer spaetere Anpassung: Ein EV-Befehlsablauf darf nicht pauschal den
+externen SDL-Auftrag loeschen. Ein Kernel-interner Timer ersetzt wiederum keinen
+Schutz bei komplettem Kernel-/Rechner-/Kommunikationsausfall.

+# V4 application data and forecast integration
+
+## Implemented application path
+
+`ManagerNetzfahrplanV4DatenTrait` records the configured raw power/SOC/counter sources
+inside the existing Manager. This replaces the need for permanent standalone
+observation categories once the native delivery path has been accepted. It never
+issues device commands. New acquisition properties default disabled.
+
+The private outbox at `data/enelix-v4/<installationId>` is append-only and delivery
+is acknowledged by dataset and capture time. Unacknowledged data survives network
+failures and 429 responses. The native payload budget is below the existing portal
+1 MiB request-body limit. Existing authentication and V4 rate limiting are reused.
+
+Server application source is now versioned under `services/netplan-v4`, rather than
+existing only as an untracked server working tree. No live measurements, databases,
+credentials, dependency binaries or settings exports are included in this directory.
+
+The existing worker handles per-plant dataset ingestion, physical five-minute
+rollup, model training, model storage and corrected-load substitution into the V4
+optimizer. It continues to consume the existing PV forecasts and price/operation
+inputs. The public device route can append measurements but cannot alter source
+meaning, register a dataset, change live permissions or arm a controlled trial.
+
+## Explicit settings and model meaning
+
+- `forecastSource=legacy` preserves the existing forecast input by default.
+- `forecastSource=corrected_profile` plus `measurementDataset` uses the trained
+  corrected physical load. Missing models are reported; legacy house values are
+  not substituted silently.
+- `trainingCadence=daily|weekly` is now connected to real profile fitting in the
+  application worker, independently from the optimizer refresh frequency.
+- Corrected load profiles are tagged `physical-profile-v1`: robust daily profile,
+  recent-day profile and weekday/weekend profile paired with PV families 3/13/23.
+  They are not claimed to be the previous load models unchanged. Economic automatic
+  selection still requires the separate, not yet finished cost-replay integration.
+- Initial models are explicitly bootstrap models. Later candidates record causal
+  holdout errors; an overlapping validation window cannot certify a promotion.
+- Current SDL request persistence is only a labelled shadow scenario. Unknown or
+  stale SDL is not silently zero, and the scenario is not a guaranteed future
+  schedule or a robust SDL-aware production control policy.
+
+## Lihrenmoos package scope
+
+Effective EV capacity 161.44 kWh and power 39 kW remain unchanged; SDL reserve is
+already excluded. The prepared dataset `lihrenmoos-physical-v1` uses a configured
+physical estimate with SolarEdge signed terminal power counted once. It requires
+at least 24 equivalent usable hours before the first bootstrap profile; the
+history window is 28 days. Coverage policy 95% with maximum 10-second unsupported
+portion is an explicit modelling assumption. Gaps and source ages remain visible.
+It is not an independent electrical metering-boundary proof.
+
+Server entry point on the service host:
+
+    python3 /home/agent/services/netplan-v4-shadow/commissioning/deploy_application.py \
+      --plant e3a08f9e-af12-4695-99bd-8b51c0520021 --apply
+
+Default without --apply checks source only. The explicit apply command rebuilds
+and tests V4 in Python 3.11, tests portal routing, backs up the V4 database and
+recreates only V4 and the portal. It configures the dataset but DOES NOT select it
+for the existing plan automatically. No forecasts/tariff importer or controllers
+are restarted by the server command. A previous-image rollback is prepared.
+
+Then, inside Lihrenmoos Symcon:
+
+    require '/srv/agent/netplan-v4-application-build/install.php';
+
+This is a data-only patch of the currently installed passive manager, with file
+backup and library reload. It does NOT install the development control-trial
+changes in Manager/Batterie. The first runtime invocation imports at most 48h of
+the existing 23-channel observer as a durable backlog, preserving the original
+files, then activates acquisition and delivery. If Symcon module registration is
+not immediately available, the installer reports that a single repeat is needed.
+
+The two temporary standalone samplers are not stopped automatically by this
+initial package; disable them only after native batch acceptance and history
+continuity are confirmed. This package creates no new root diagnostic category.
+
+## Validation performed before deployment
+
+219 Python tests passed in the isolated host QA runtime, including actual synthetic
+measurement -> profile -> existing optimizer -> stored shadow plan. 16 Node proxy
+checks passed. 21 PHP data-path checks and 5 installer scenarios passed with mocked
+IPS/HTTP and temporary files on the test host. Full staged PHP syntax passed.
+No new container or new manager data integration has yet been run in production.
+
+Evidence: service `APPLICATION_PIPELINE_TEST_RESULTS.txt`,
+`APPLICATION_PORTAL_TEST_RESULTS.txt`, `commissioning/application-source/RELEASE.json`;
+test host `netplan-v4-application-build/PREPARATION.json` and `TEST_RESULTS.txt`.
+
+## Remaining product scope (do not disguise as complete)
+
+This integrates application data and load forecasting, not completed production
+commissioning. Economic replay-based automatic family selection, full corrected
+feedback/control integration, long-term outbox/server retention and real live/
+failure acceptance remain open. Existing trial gates are unchanged. No sensor,
+accounting or hardware evidence identifier is fabricated by data ingestion.
+
+## Installer class-path correction (2026-10-03)
+
+The original commissioning installer loaded `source/libs/NetzfahrplanV4Messaufnahme.php`
+while importing observation history. A later Manager callback loads the installed
+copy at `modules/Enelix-EMS/libs/NetzfahrplanV4Messaufnahme.php`. PHP's once-only file
+inclusion does not deduplicate class declarations across those different files.
+The dependent `NetzfahrplanV4Bilanzierung` class is subject to the same collision.
+
+The tested installer-only fix is preserved in
+`examples/V4ApplicationData/application-class-loading.patch` (SHA256
+`6d53d74d4059bb1ae3a446350637a4f4a4a73cc2fd64d2fc2f0967bd23ec7173`).
+When building a commissioning package, load both classes only from the installed
+module tree, after validating their expected source hashes. Before any require,
+check both already-loaded origins without autoload. Reject a foreign staged origin
+with a controlled error; do not hide it by wrapping the class declaration in a guard.
+Include `installed_capture_bootstrap.php` in the package checksum map. Do not change
+the installed-module manifest or bless unrelated source changes.
+
+The Lihrenmoos staging entrypoint has this fix applied, with backups of its original
+installer and checksum map. No running modules, data files, timers, native callbacks,
+server components or actuator settings were changed by the repair. Actual completion
+still requires the user's fresh Symcon invocation of the corrected installer.
+
+Validation: the original two-path failure was reproduced with the real PHP classes.
+Thirteen additional isolated installer scenarios passed, including callback/reload
+loading order, preloaded dependencies, history import, repeat/finished import,
+foreign-class refusal, partial-import preservation, source drift, registration wait
+and first installation. These are PHP CLI tests with mocked IPS in temporary trees,
+not a completed test in the actual Symcon kernel.
+
+Evidence on the test host:
+`/srv/agent/netplan-v4-application-build/class-loading-fix/TEST_RESULTS.json` and
+`FIX_RESULT.json`. The test harness and exact candidate source are retained there.

+# V4: begrenzter Regeltest (Entwicklungskandidat, NICHT in Betrieb)
+
+Stand 2026-10-02. Diese Erweiterung ist weder Produktionsfreigabe noch ein
+Installations-/Startauftrag. Bestehende Schattenplaene und ihre `shadow_seen`
+Bestaetigungen bleiben unveraendert. Ein Vorschauwert allein darf niemals
+als Stellfreigabe interpretiert werden.
+
+## Freigabekette
+
+1. Serverseitige separate Allowlist `NETPLAN_V4_CONTROL_TRIAL_PLANTS` (standardmaessig
+   leer). Interner authentifizierter `planner/trial/arm`-Aufruf mit expliziter
+   Bestaetigung, neuer Sitzung, gepruefter Plan-ID/Revision, Batteriezuordnung,
+   Zeitfenster, Leistungsgrenzen und dokumentierter Geraete-Watchdog-Abnahme.
+   Die bestehenden oeffentlichen Portal-/Geraeterouten proxien diesen Aufruf NICHT.
+2. `NetzfahrplanV4RegeltestErlaubt` lokal im Manager UND im Batteriemodul (jeweils
+   Standard false). Alte `NetzfahrplanAktiv`-Freigabe muss false bleiben.
+3. Zusaetzlicher bewusster lokaler Start einer bestimmten Sitzung. Ein Reload,
+   Netzwiederkehr oder gespeicherter Haken startet keine Sitzung automatisch.
+4. Der Manager prueft den empfangenen Schattenplan und die getrennte
+   `controlled_trial_authority` gemeinsam. Sie sind gebunden an Anlage, Batterie,
+   beide Instanz-IDs, Revision, manuelle Modellfamilie und stabilen Planungskontext.
+5. Die Batterie nimmt nur einen separaten `controlled_trial_command` mit eigener
+   Sequenz und kurzer Gueltigkeit an. Normale Managerbefehle erneuern diese
+   Gueltigkeit nicht. `shadow_seen` bleibt eine Empfangs-, keine Ausfuehrungsmeldung.
+
+Die Serverantwort bleibt eine Schattenplan-Antwort (`liveEnabled:false`). Eine
+getrennte Testfreigabe ist unter `controlledTrial` und
+`controlledTrialAuthorized` sichtbar. Der Schattenmodus allein ist bei kuenftig
+bewusst gestartetem Test deshalb kein Nachweis fuer 'keine Batteriebewegung'.
+Die Controller-Diagnosen benennen eine angenommene Sollvorgabe, nicht bereits
+physisch gemessene Umsetzung oder Ersparnis.
+
+## Bewusst begrenzter Pilotumfang
+
+- Genau eine eindeutig zugeordnete Batterie je Test; Familie manuell festgelegt.
+- 30 bis 1800 Sekunden Sitzung, maximal 5000 W Laden und 5000 W Entladen.
+- Server-, Manager- und Batteriegrenze koennen strenger sein; nie grosszuegig
+  ersetzen oder still auf 39 kW hochsetzen.
+- Gesamtsollleistung, NICHT Zusatzleistung zur bereits fliessenden Batterieleistung.
+- Andere Verbraucher bleiben im alten Verteiler. Ihre erwartete Leistungsaenderung
+  wird einmal bei der Batteriekorrektur beruecksichtigt.
+- Batterie wird nur einem Stellwertpfad zugeteilt, nicht gleichzeitig dem alten
+  und neuen Verteiler. Ist der Test ungueltig, stoppt er und es wird eine NEUE
+  normale Verteilung angefordert; kein alter gespeicherter Sollwert wird restauriert.
+- Physische Grenzverletzung, die innerhalb der Pilotleistung nicht behebbar ist,
+  beendet den Test zugunsten der bestehenden lokalen Regelung.
+
+## Ausfall- und Zeitverhalten
+
+- Serverfreigabe maximal 90 Sekunden, lokal regelmaessig frisch abgerufen.
+  Serverseitiger Widerruf wirkt nicht magisch sofort: Cachefrist beachten.
+- Einzelner Batteriebefehl maximal 10 Sekunden; Batterie kontrolliert im laufenden
+  Kernel mit 1-Sekunden-Timer zusaetzlich zu Messwert-Callbacks.
+- Manager liefert kurze Befehle im Test mit zusaetzlichem 2-Sekunden-Takt.
+- Monotone Laufzeit und Kalenderzeit werden getrennt geprueft. Eine rueckwaerts
+  springende Systemuhr darf eine Sitzung nicht verlaengern.
+- Abbruch widerruft die Sitzung VOR dem Nullstellversuch. Schreibfehler werden als
+  `stop_failed`/nicht bestaetigter Stopp sichtbar, nicht als sicherer Zustand.
+- Reserve, Hysterese, aktuelle Lade-/Entladeleistung, SOC und Verfuegbarkeit werden
+  auch im Batteriemodul erneut geprueft. Sicherheitsreduktionen werden nicht durch
+  die Umschaltsperre verzoegert; Richtungswechsel laufen ueber null.
+- Laufzeitsitzungen liegen nur im Buffer, nicht als automatische Wiederanlauf-Freigabe.
+  Ein persistenter Marker sorgt bei Wiederinitialisierung fuer einen erneuten
+  Nullstellversuch, falls ein Testwert zuvor ausgegeben worden sein koennte.
+
+WICHTIGE GRENZE: PHP-Timer und Software-Nullstellversuche funktionieren nur bei

+# V4 corrected physical feedback -> local bounded control
+
+## Scope of this delivery
+
+The shared physical feedback reader is now connected to the actual Manager preview,
+the existing explicit bounded-trial command path, and an independent reread in the
+Battery module immediately before hardware output. This is not a new observer.
+The installer leaves both local trial permissions disabled and cannot arm a server
+trial. Normal operation continues through the existing local controller.
+
+Lihrenmoos binding: Manager 17004, Battery 44234, virtual asset
+`anlage01-virtual-ev`. Effective 161.44 kWh / 39 kW unchanged. Source definitions
+come from the existing versioned capture config and current saved topology, not
+from new guessed device models. No old histories, sender cursors, virtual energy
+accounts, SDL requests, archive policies or inverter polling are changed.
+
+## Feedback and meaning
+
+`NetzfahrplanV4Rueckmeldung` checks original value timestamps and object identities
+in two read passes. Live max age is bounded to 60s and inter-source skew to 30s.
+History interpolation/publication estimates are not accepted as live feedback.
+The mapping fingerprint normalizes numbers and ordering, so a JSON property round
+trip does not create a new identity. A mapping change cancels an active session.
+
+Two adapters exist: sum of explicitly assigned physical meters, and a virtual
+EV/SDL partition model. For the latter, gateway state and current requests are
+read but unchanged zero commands are not mistaken for failed sensor heartbeats.
+When SDL request is exactly zero, current physical battery power is used rather
+than the filtered virtual EV display. A new EV request does not invent an immediate
+physical response or force the measured sign toward the desired sign.
+
+When SDL is nonzero, source timestamps must cover the latest request change and
+physical tracking error must remain within the configured small tolerance. The
+partition is explicitly estimated, not separately measured. Opposing EV/SDL flows
+cannot be uniquely identified; they remain ineligible for trial control. Unknown
+or stale physical sources never fall back to held filtered EV values.
+
+`allowEstimatedForTrial` is false in the prepared Lihrenmoos config. Configuring
+feedback or seeing a valid preview therefore does NOT accept the estimate for a
+trial and does NOT satisfy accounting/device-watchdog evidence or other gates.
+This adapter does not claim to resolve arbitrary simultaneous SDL activity.
+
+## Actual control integration
+
+The same coherent grid/battery snapshot is used in the Manager. Battery command
+is a TOTAL power, not a delta added to the existing command. Planned changes in
+other consumers are counted once and remain explicitly separate from measured grid.
+
+A separate explicit server authority, both local consents, accounting evidence,
+device-watchdog evidence, a deliberate session start and fresh plan remain required.
+The existing trial is limited to 1800s / 5000W per direction; individual command
+leases remain <=10s and cannot be renewed by replay or ordinary manager messages.
+The local feedback mapping fingerprint and grid caps are bound to the session.
+
+Immediately before writing, Battery rereads physical feedback and applies current
+SOC, reserve, hysteresis, availability and change-lock constraints. Its resulting
+command must still meet the bound grid limits; an unreachable target revokes the
+trial rather than claiming that the planned grid value was achieved. It cannot
+claim physical performance merely because a register call returned successfully.
+
+Abort revokes the lease and attempts zero, and the Manager wrapper then runs at
+most one fresh ordinary allocation, clearing cached pre-trial targets. It does
+not recurse forever or revive an old plan. A failed stop stays explicitly failed.
+The watchdog still requires a functioning kernel. Independent hardware failure
+behavior is NOT certified by software tests.
+
+Outside a V4 session the existing battery power path is unchanged. The compatible
+BatterieRegler library includes the already developed optional reserve charging
+limit; with its default (maximal charge) 13,824 old/new ordinary-offer test cases
+match exactly. That comparison is not an on-device dynamics test.
+
+## Installation
+
+A single prepared Symcon script is the next runtime action:
+
+    require '/srv/agent/netplan-v4-feedback-stage/install.php';
+
+It hash-checks nine changed files and all version-matched dependencies, backs up
+existing source, installs dependencies before modules and reloads the ENELIX
+library. Reload/ApplyChanges may execute existing initialization routines; this
+is not promised to be a zero-effect library reload. It configures only the new
+feedback mapping on Battery. No server redeployment is required. No shared classes
+are included from staging, avoiding the earlier duplicate-class problem.
+
+A delayed module-registration result requests one repeat. A valid installation
+can still report an unavailable feedback sample; that is not reinterpreted as zero.
+Any preexisting trial permission, unsaved change, or concurrent source change stops
+the installer. Source write failure rolls back its own changed files; reload errors
+are reported for review and do not automatically authorize anything.
+
+## Validation and remaining acceptance
+
+125 isolated PHP functional checks cover the reader, real receiver, actual trial
+traits with a simulated register driver, the extracted actual Manager fallback
+wrapper, and the real Battery message builder with optional diagnostic variables absent.
+Source quality is stored internally; a last partition estimate is not relabelled as a
+measured value just because a trial ends or a diagnostic variable is hidden. Four full module linkage checks and ten isolated installer scenarios also
+pass. Full PHP syntax and dependency hashes are checked. Neither these fixtures nor
+the ordinary-offer comparison run the real Symcon kernel or an inverter.
+
+Evidence: test host `/srv/agent/netplan-v4-feedback-stage/PREPARATION.json`,
+`TEST_RESULTS.txt`, `INSTALLER_TEST_RESULTS.json`, `ORDINARY_OFFER_TEST.json`.
+
+Runtime installation, real feedback reception, and a separately authorized field
+trial remain outstanding. This finishes the code connection for bounded control;
+it is NOT an unrestricted continuous-production controller or a hardware
+commissioning certificate. Corrected model selection and actual real-world savings
+must be checked against their own data. Existing safety gates are not bypassed.

+# Passive V4 data capture - user inventory and raw acquisition
+
+Status 2026-10-02: source implementation, CLI/mocked tests and staged user installation.
+Not part of the live manager, not a control or training release.
+
+## Lihrenmoos user-reported inventory (not applied to running configuration)
+
+- GoodWe 1/2: each 50 kW AC, each 156 kWh reported physical battery capacity.
+- SolarEdge: 10 kW AC, 10 kWh reported physical battery capacity.
+- EV allocation: 30 kW / 160 kWh total, understood as 10 kW EV per inverter.
+- PV roof: approximately 20 kWp east and 20 kWp west. Tilt/individual strings unknown.
+- Nominal battery sum: 322 kWh. 162 kWh nominal difference to EV allocation is NOT a
+  verified usable SDL capacity. AC ratings are not verified battery charge/discharge ratings.
+- Exact types, firmware, common AC meter boundary and device watchdog remain unverified.
+- Current saved manager topology still reports 161.44 kWh / 39 kW. Gateway currently
+  lists 130/130/8 kWh and 57/57/5 kW. These may use a different usable/nominal basis.
+  Do not rebase virtual SOC or change current controls based on these notes alone.
+
+## Why collect before boundary approval
+
+Record the actual original numerical channels now, with source metadata and timestamps.
+The algebraic base-load candidate is useful for diagnosis, but NEVER a certified base-load
+training sample until the physical AC/DC boundary and historical recipe are verified.
+No dependence on hardware-watchdog approval for passive recording.
+
+21 channels: PCC power, legacy displayed PCC power, PV for three inverters, three physical
+battery powers, EV/SDL virtual powers and SOCs, three physical SOCs, dynamic EV limits,
+T1/T2 import counters, EV/SDL requested setpoints (READ ONLY).
+A cyclic script reads values already present in Symcon every 30 seconds. It does not issue
+additional Modbus polls. Original VariableUpdated/VariableChanged are retained; these are
+Symcon timestamps, not independent device-measurement timestamps. Two-pass reads detect
+concurrent changes; missing/non-numeric/re-used channels remain explicit quality failures.
+
+## Storage and interpretation
+
+Daily append-only raw-YYYYMMDD.jsonl in the separate capture stage data directory, UTC
+capture times plus original source timestamps, immutable mapping/inventory snapshots by
+SHA256. Raw errors and quality_hold are recorded too; nothing is invented as zero.
+The raw observations are a source for later documented 5-minute aggregation, not themselves
+aligned 5-minute means. No interpolation, training publication or future SDL assumption.
+
+A 512 MiB journal quota, 64 MiB daily limit, 256 KiB record cap and 100 MiB free-space
+reserve bound recording. Limits fail visibly without deleting old data. File permissions
+0640; no upload credentials, request bodies, complete instance configurations or secrets.
+A separate status variable and STATUS.json show latest capture and failures. Process restart
+retains files; an incomplete final JSONL row is preserved for manual review, not extended.
+
+## Install / stop
+
+Staged user entry point: /srv/agent/netplan-v4-data-capture-stage/install.php
+Execute in the Symcon PHP editor (not a Linux shell):
+
+    require '/srv/agent/netplan-v4-data-capture-stage/install.php';
+
+Installer checks exact source hashes and numeric source identities before creating a NEW
+root category ENELIX_V4_PASSIVE_CAPTURE, a status string, collector script and stop script.
+IPS_SetScriptTimer enables only this new script at 30 seconds. Repeating installation is
+idempotent. Unrelated/edited scripts or object identity collisions are not overwritten.
+
+Stop using the newly created script 'Nur diese Messaufnahme stoppen'; it disables only
+this collection timer, retains collected files, and does not stop the manager or battery.
+No module reload, existing archive change, existing timer/poller change, service restart,
+forecast selection, battery reservation or actuator command is included.
+
+Current tests: 36 core/file tests + 19 mocked native lifecycle tests with PHP CLI on the
+test host. First real capture and future timer execution require the user activation.
+These tests do not certify hardware mappings or a Symcon-kernel run.

+# Historical publication timing (2026-10-03)
+
+## Implemented scope
+
+`services/netplan-v4/netplan_v4/history_timing.py` implements optional, bounded
+retrospective estimates between consecutive identical source values at DIFFERENT
+original publication timestamps. It is used by the existing measurement pipeline,
+model training and forecast source substitution. It is NOT a real-time estimator,
+a measurement certificate, an actuator authority or a repair of device communications.
+
+No source `maxAgeSeconds` is changed. When a regular hold expires, only its tail
+until the next qualifying original publication may be estimated. Strict processing
+remains the default. The following forbid the estimate: unequal endpoints,
+nonfinite/missing observations, conflicting same-timestamp values, collector gaps,
+invalid source intervals or a span beyond the explicit source-specific bound.
+There is no extrapolation past the last observation and no fabricated zero.
+
+Each window reports `publicationEstimatedSeconds`, per-source estimated portions,
+uncovered-source seconds and `availableNotBefore`. Training/validation must not use
+a confirmation or receipt before it was actually available. Backfilled windows
+cannot establish a supposedly causal holdout at a date before their availability.
+All physical windows remain configured estimates; even full support is not proof
+that the physical waveform stayed constant between the two endpoint readings.
+
+## Evidence and model assumptions
+
+Read-only source configuration projection on the test server, snapshot
+2026-10-03T07:47:24Z: GoodWe 1 instance 19742 (ModBus Device) has Poller 60000 ms;
+GoodWe 2 instance 57658 has Poller 5000 ms; SolarEdge scale instance 48996
+(ModBus Address) has Poller 20000 ms. No polling setting was changed.
+Projection program: /srv/agent/netplan-v4-application-build/inspect_source_update_policy.py.
+
+Official Symcon documentation accessed on 2026-10-03:
+https://www.symcon.de/de/service/dokumentation/modulreferenz/geraete/modbus-rtu-tcp/vorlagen/
+It documents value publication for ModBus Device on changes or when the variable is
+older than 60 seconds, including ordinary and virtual addresses. VariableUpdated
+is therefore not automatically the last successful device poll. The documentation
+is not a proof that a particular installed device link was healthy.
+
+Explicit Lihrenmoos HISTORICAL estimate bounds:
+- GoodWe 1 PV/physical storage: equal original publications at most 130 s apart
+  (60 s publication suppression + configured 60 s poll + 10 s scheduling allowance).
+- GoodWe 2 PV/physical storage: at most 75 s (60 + 5 + 10).
+- SolarEdge scale: equal scale publications at most 90 s apart. This is a modelling
+  bound based on the configured 20 s polling and observed sparse scale publication,
+  not a manufacturer guarantee and not proof of the same internal implementation
+  as ModBus Device. Raw AC power remains under the original strict limit.
+The 10 s margins are explicit scheduling assumptions, NOT measured timing guarantees.
+Gaps of many minutes (e.g. the previously observed GoodWe gaps above 600 s) are NOT
+bridged. Nonzero changes are never interpolated by this policy.
+
+## Versioned dataset without restarting collection
+
+`lihrenmoos-physical-published-v2` references immutable observations in
+`lihrenmoos-physical-v1`. No observations are copied, deleted, relabelled or resent.
+Registration requires the same installation and identical original mapping,
+formula, coverage and training configuration. Cycles/reference chains and device
+uploads directly into a derived dataset are rejected. Original ingestion continues
+unchanged in the Manager. The 24 usable-hour minimum stays in force.
+
+Models/windows are stored separately for v1/v2 and record their timing policy. An
+existing selected model/family is not automatically switched by this release.
+The current SDL request still uses the strict current-state requirements; no
+historical bridge grants a future SDL schedule or a live battery permission.
+
+## Tests and release
+
+254 isolated Python tests passed (219 previous + 35 new including simulated
+installation/recovery). Includes the actual service pipeline from referenced
+observations to model and optimizer using synthetic records. No new target-container
+or field-history evaluation has been run with this release yet; do not infer an
+improved real coverage percentage or production acceptance from unit tests.
+Evidence: /home/agent/services/qa/history-timing-20261003/ALL_TEST_RESULTS.txt.
+
+Prepared command on enelix-services (root required for Docker):
+
+    python3 /home/agent/services/netplan-v4-shadow/commissioning/deploy_history_timing.py \
+      --plant e3a08f9e-af12-4695-99bd-8b51c0520021 --apply
+
+Default without --apply validates staged source only. The apply path backs up source
+files, builds and runs the exact target tests, backs up the V4 SQLite database, and
+recreates ONLY the V4 service. A failed test restores source without a service
+restart; failed post-deploy validation attempts the previous image and preserves
+additive data. Concurrently modified files are not silently overwritten.
+
+No portal/forecast/tariff/Symcon restart, no new sensor requests, no change to
+161.44 kWh / 39 kW, SOC accounting, old raw samplers or actuator permissions.
+The new dataset is registered but not selected for the active forecast. A root
+execution and successful report are still required to install it. Previous release
+manifests remain historical records; do not bypass them to reapply an older build.

+# Numeric mapping identity defect - 2026-10-03
+
+## Confirmed from installed code and read-only evidence
+
+The pending batch contains 120 observations: zero duplicate timestamps, zero
+backwards pairs, but 75 identity failures. The initial 45 observations in this
+batch are imported observer records; later native captures use the saved manager
+configuration. Evidence: test-host `PENDING_DELIVERY_REVIEW.json`.
+
+The configured mapping fingerprint is
+`517d1907631c7f152096e21759bb3452cdd0b4b1b73f91f1c7cd3bd62d8aaa8b`.
+Reproducing native configuration loading generates
+`3a1a9cf42aae49f55385d2350da74cae780ae12f170e4976849591e48a393994`.
+The sole difference in the compared configurations is numeric representation of
+`accounting.splitToleranceW`: prepared float 100.0 versus saved integer 100.
+Both inventory fingerprints and all measurement definitions match.
+`NetzfahrplanV4Bilanzierung::konfigurieren` validated this field using a function
+which returns a float, but discarded the normalized return value. Other numeric
+factors were already assigned from that validator.
+
+## Tested source correction
+
+Assign the returned float to `splitToleranceW`. Equal numeric settings now retain
+the original fingerprint through a plain JSON property round trip. Actual numeric
+changes still produce distinct fingerprints, and boolean/string values are still
+rejected. Input configurations are not mutated.
+
+42 isolated PHP checks passed on the test host: 34 accounting regressions plus
+8 numeric identity regressions. A separate check with the actual prepared capture
+configuration reproduces the configured fingerprint after the property round trip.
+Evidence: `/srv/agent/netplan-v4-application-build/NUMERIC_MAPPING_TEST_RESULTS.json`
+and `NUMERIC_MAPPING_TEST_RESULTS.txt`. Library SHA256:
+`ffda2a03dbb226a4405a2ad66704c080a9dc475ce64282ad3f0d7d60034ab199`.
+
+## Not deployed / recovery still incomplete
+
+No installed library, original outbox, cursor, server validator, settings, dataset
+registration or actuator permission was changed in this turn. Future-capture
+normalization alone does not recover already stored native observations. The
+server correctly rejects an entire batch containing a mismatched mapping.
+
+An untested proposal to send distinct immutable dataset versions in separate
+batches was removed from the development source and preserved only as a draft at
+`/home/agent/services/qa/numeric-mapping-20261003/UNTESTED_SENDER_DRAFT.patch`.
+Metadata preparation files are not an installation or permission to ingest into
+an unregistered dataset. Tool writes for the complete server recovery package were
+blocked; no alternative deployment or identity-check bypass was performed.
+
+Next recovery must preserve original records and provenance, retain exact
+per-dataset identity validation, acknowledge only accepted data and include tests
+for the mixed 45/75 batch, retries, partial ACKs and no cursor/data loss. Do not
+skip the rejected block, rewrite hashes in raw journals or re-run old installers.

+# V4 plan reception and local preview (observation only)
+
+This module does not execute a battery command. The existing regulator and its
+setpoints remain unchanged. `NetzfahrplanAktiv` must remain false.
+
+The optional `NetzfahrplanV4EmpfangAktiv` property defaults to false. When enabled
+with the existing shadow sender, one bounded GET is made before the next native
+operation POST, avoiding reading the plan immediately after queuing its replan.
+A successful inspection acknowledges `shadow_seen` once per plan/step. This is
+not `applied`. An HTTP failure clears the local preview; it does not change the
+old control mode or its connection credentials.
+
+The V4 service must first support `receiverProtocolVersion=1`, installation IDs
+in envelope and plan, per-input event references, and the stable controlContext
+used at calculation time. Old or cross-plant responses are deliberately refused.
+The client checks fresh/lastRun/pending status, exact configuration revision,
+model-family registry, known price coverage, contiguous half-open five-minute
+intervals, asset mapping and power balance. Numerical feasibility checks are
+not evidence of economic performance or permission to control devices.
+
+A cache watchdog refreshes the diagnostic display every 10 seconds, without any
+network requests. Cached response older than 90 seconds, plan older than 900
+seconds, an expired step, invalid local measurement or policy change invalidates
+the preview. Missing targets are JSON null and '-' in the display, never zero.
+Restart/ApplyChanges clears the cache. Existing control functions are not edited.
+
+The preview is currently limited to ONE battery. Multiple batteries are still
+accepted by the server planner; local allocation is explicitly unsupported in
+this stage. Preview feedback uses actual grid and battery power, local capacity,
+available power, minimum/maximum SOC, discharge hysteresis, network-charging
+permission and import/export/month limits. It exposes any remaining grid-limit
+violation instead of pretending the battery can resolve it. It is a momentary
+calculation only, NOT the commissioned real-time regulator. PV curtailment and
+external SDL/base-load separation must still be validated before any live test.
+
+Two read-only variables below the manager expose a HTML summary and detailed
+JSON. No EnableAction, consumer RequestAction, SendData or actor property writes
+are used. The existing form.json and web portal assets are not modified.
+
+Offline checks:
+
+    php tests/V4Receiver/protocol_checks.php
+    php tests/V4Receiver/receiver_checks.php
+
+The PHPUnit wrapper runs these in separate subprocesses, so fake IPS and curl
+functions cannot contaminate other module tests. The mocked transport uses no
+real credentials or connections. Full Symcon kernel testing and installation
+are separate commissioning steps; these unit tests are not field acceptance.

+# Separate physical load / EV-SDL observation (NO dispatch or training permission)
+
+## Implemented 2026-10-02
+
+- `NetzfahrplanV4Messsicht` recalculates independent physical-load, physical-storage,
+  unfiltered modelled allocation and SolarEdge-origin views from explicitly identified
+  raw snapshots. Quality failures in held virtual accounts do not veto otherwise
+  consistent physical inputs. Missing/stale physical inputs still invalidate their
+  respective view. No automatic relaxation of age/skew limits.
+- EV/SDL model: delta = physical - requestedEV - requestedSDL; distribute delta in
+  proportion to the absolute requested powers. The SDL component is obtained from
+  physical minus modelled EV to preserve numerical closure. This is an accounting
+  convention, NOT independently measured EV and SDL and NOT a verified response.
+- Command changes more recent than the oldest physical feedback are flagged. Unknown
+  change timestamps, tracking mismatch, aged/missing origins and idle unallocated
+  power remain explicit. There is no held-value filter and no forced convergence of
+  displayed power to the requested value. All proposals keep `canDispatch=false`.
+- Actual legacy filter outputs are displayed solely for comparison. They are not
+  reused as inputs of physical-load or unfiltered partition calculations. No changes
+  to the legacy filter, physical driver, EV/SDL setpoints, SOC integration or accounts.
+
+## New read-only origin finding
+
+Selected event 38921 writes legacy PV variable 20335 using:
+
+    a = 10 ** GetValue(41853) * GetValue(37975) + GetValue(21447)
+    if (a < 0) a = 0
+    SetValue(20335, a)
+
+Arithmetic statements were inspected without exposing arbitrary scripts/credentials.
+Verified saved configuration: variable 37975 parent 35514, register 40083; scale
+41853 parent 48996, register 40084; battery 21447 parent 30789. An independently
+updated 20335 is therefore not an independent PV reading and cannot certify all
+input timestamps. A second constrained arithmetic read confirmed the condition
+`if ($a < 0)`; this clamp applies to the legacy calculated PV value, not to the
+new signed terminal-power observation. Neither proves the full AC/DC boundary.
+
+The staged observer additionally records the ORIGINAL mantissa and exponent, not
+only their periodically rewritten derived PV result. The alternative candidate
+uses the scaled terminal power ONCE for this inverter (removing its derived-PV
+and battery terms). GoodWe AC/DC boundaries and full-site physical boundary are
+still unverified. This is not a definitive corrected house meter or live forecast.
+
+## Standalone installation / operational scope
+
+Stage on test host: `/srv/agent/netplan-v4-separated-observer-stage`.
+User invocation inside Symcon only:
+
+    require '/srv/agent/netplan-v4-separated-observer-stage/install.php';
+
+Creates only a NEW root category, three textual diagnostic variables, observe and
+stop scripts and a NEW 30-second timer. Reads 23 existing numeric variables twice;
+no Modbus polling requests, network calls, archive settings, existing module or
+control timer updates. Existing 21-channel raw collector continues untouched.
+
+New daily journals contain the selected numeric raw snapshot and derived views.
+A new immutable mapping/inventory reference binds the corrected user EV allocation
+161.44 kWh / 39 kW. Original collector metadata and its correction addendum remain
+unchanged. No rescaling or resetting of virtual SOC/energy accounts.
+
+Derived journal and LATEST/STATUS reports are 0644 WITHIN mode-0700 private stage
+and data directories, allowing the authorized agent to inspect these selected
+new outputs without repeated manual exports. No permissions on original journals,
+Symcon directories or unrelated data are changed. Quotas reuse 64 MiB/day, 512 MiB
+in total and 100 MiB disk reserve; exceeding them stops recording visibly and does
+not delete old data. No network transfer or cloud trainer is activated.
+
+## Validation and limitations
+
+40 pure view checks + 32 native-mock checks passed on PHP 8.3 CLI at test host.
+Regression: 36 raw-capture + 19 native-capture + 34 accounting checks passed with
+new additive `raw_power`/`scale` units. Total 161 isolated checks. Full relevant PHP
+source lint passed. Not a full PHPUnit run, Symcon kernel trial or hardware test.
+
+Tests cover opposite EV/SDL requests, held output, non-unique partition labelling,
+negative terminal power, scale/sentinel validity, old dependency timestamps, changed
+commands, missing source, no duplicate native objects, unchanged existing signals,
+append preservation, source drift, private output restrictions and stop behavior.
+
+The observer is PREPARED, not started by the assistant. It does not replace the
+installed receiver or its existing preview calculation. The preview/driver must
+only be switched after measurement-boundary and feedback policy acceptance. Model
+training and five-minute reconstruction must consume the new versioned snapshots
+separately; there is no training eligibility or zero future-SDL assumption here.
+
+Device-side command-loss protection and exact model/firmware identification remain
+open. Official SolarEdge PDF fetch was unavailable (403/error); no device-specific
+register suitability or watchdog behavior was inferred from a third-party source.

+# V4 Unified RC1 - actual scope and release boundary
+
+This release consolidates application data recovery, native delivery status, economic
+family comparison, and optional verified archival. It is NOT a production actuation
+release. No claim that all original product requirements or hardware acceptance are
+complete. Sources are in the existing develop branch, not feature branches.
+
+## Delivered code
+
+* Audited recovery for the exact 100.0/100 splitToleranceW serialization defect.
+  The internal operator endpoint validates the two complete JSON representations,
+  their exact SHA256, installation, inventory, and every field. Only that numeric
+  representation may differ. Device-supplied arbitrary aliases are never accepted.
+  Existing rows/measurements are not rewritten. The original received mapping and
+  proof reference are recorded with the observation. A mixed 45/75 block and retries
+  are regression tested. Adoption requires an explicit deployment flag.
+* Native normalization prevents recurrence. The sender preserves a separate last
+  successful receipt even during scheduled/backoff states, reports safe numeric HTTP
+  status (no response or credential text), and continues trying to deliver a durable
+  prefix if the current capture cannot be appended. No cursor reset or skipped block.
+* Economic comparison is actually connected, not an empty score list. At the start
+  of a local calendar day the worker freezes comparable plans for families 3/13/23
+  with the then-known forecasts, prices and common battery/limit state. Completed
+  days are evaluated against subsequently acquired physical residual data. Initial
+  energy, losses, common terminal energy valuation and 15-minute demand charge are
+  included; monthly maxima are charged once over a comparison period, not per day.
+  GUI lookback/minimum days/coverage/switch margin are applied by the selector.
+* v1 economic scope: one grid-charge-enabled battery, frozen day-ahead plans, with
+  local grid-target tracking simulated during the day. It is NOT a full receding-
+  horizon replay. Historical external SDL uses the then-recorded SDL request and is
+  clearly marked as an estimate, not independently measured delivery. Missing
+  actuals, unmatched contexts and breaches cannot become zero cost or a successful
+  comparison. Broader device topologies stay collecting; no fake equivalence.
+* Lossless archive implementation and tests are present for acknowledged old native
+  outbox days and old server observations/plans. Archives are verified before plain
+  rows/files are retired. Active plans, acknowledged plans and unacknowledged data
+  are excluded. Archiving is OFF by default; enable only with an explicit storage
+  policy (native NetzfahrplanV4ArchivAktiv; server NETPLAN_V4_ARCHIVE_ENABLED=1).
+  Compressed archives are retained: this is not an external backup or infinite disk.
+
+## Deployment is not data/model/actuator acceptance
+
+Server entry: commissioning/deploy_unified_release.py. Default checks sources only.
+--apply builds and tests a separate candidate context with no network/production
+mounts before replacing the V4 service. It preserves the running plant allowlist,
+backs up SQLite consistently, and uses a pinned built image. Only the V4 planner JS
+asset is updated; unrelated GUI work, portal runtime, tariffs, forecasting, Symcon
+and actuators are untouched. Rollback restores previous source/image; additive audit
+rows remain. Database schema changes do not overwrite old observations.
+
+--approve-numeric-mapping-compatibility explicitly authorizes the demonstrated pair
+of equivalent configuration representations. Without it, strict original validation
+remains and backlog containing the legacy serialization is still rejected.
+
+Lihrenmoos native stage: /srv/agent/netplan-v4-unified-release/install.php.
+This patches three data-only libraries, reloads the existing library, compares all
+pre-existing properties and lets the existing data timer resume. No raw replay,
+force-skip or actuator callback from the installer. Archiving stays disabled by default.
+
+## Remaining product work - do not label as complete
+
+1. The full production dispatcher is not installed. Earlier controlled-trial code
+   still has bounded pilot grants; continuous production authority and complete
+   corrected physical/virtual feedback integration are NOT delivered by this RC.
+2. The actual host/container/kernel and field acceptance of this release are not
+   replaced by CLI mocks. Real source validity and independent command-loss behavior
+   are not asserted by a measurement algebra or an override.
+3. The replay limitation above must be accepted as a beta feature, or extended to
+   continuous rolling reoptimization and additional asset types before advertising
+   the original full automatic-selection requirement.
+4. Native multi-plant commissioning, external backups, retained archive lifecycle,
+   model quality on field data and publication authentication remain operational
+   release criteria. The tests do not demonstrate actual cost savings.
+
+Do not re-run obsolete piecemeal installers after this release, bypass their source
+checks, turn the previous grid schedule on, or turn 'productionReady' true manually.
+The retained EV capacity is 161.44 kWh / 39 kW; SDL reserve is already outside EV.

+# Prognosebedienung im bestehenden Manager
+
+Stand: 06.10.2026. Gepruefter Integrationsstand zur von Daniel freigegebenen
+Veroeffentlichung auf develop und beta. Kein Deployment und keine neue Stellfreigabe.
+
+## Umfang
+
+Der separate Formularbereich `V4 Planempfang / Prognosemanager` entfaellt.
+Empfang, Planpruefung, Lizenzportal-Verweis und explizites Ein-/Ausschalten
+stehen im bestehenden Bereich `Prognose / Forecast`.
+
+Der neue Formularaufruf `FormNetzfahrplanSchalten` delegiert an den vorhandenen
+`V4ManagerAktivtestSchalten`-Pfad. Er prueft beim Start nochmals gespeicherte
+Prognosekonfiguration, Netzfahrplanlizenz, Managerstatus und bestehende lokale
+Testfreigaben. Ein Formularaufruf allein erteilt keine Berechtigung. Ausschalten
+bleibt auch nach Lizenzverlust moeglich. Der bestehende Stopp beinhaltet eine
+frisch berechnete normale Regelung nach Widerruf der V4-Sitzung; er ist kein
+anlagenweiter Not-Aus und veraendert keine unabhaengigen SDL-Auftraege.
+
+Die Anzeige nennt weiterhin Testbetrieb und das bestehende Testende. Es gibt
+keine neue Dauerbetriebsfreigabe, keinen Reset der 48-Stunden-Frist und keine
+Aenderung an Watchdog-Ausnahmen, Messwertgrenzen oder Geraeteschutzpruefungen.
+
+## Kompatibilitaet
+
+- Keine Properties, Attribute, Objekt-IDs, Timer, Datenpfade oder Backend-APIs werden migriert.
+- Prognosemodelle, Optimierer, Planempfang, ACKs, Messaufnahme und Versand bleiben unveraendert.
+- Die vorhandene Portalpruefung fuer `grid_schedule` bleibt massgeblich. Keine Portal- oder Lizenzbestellung wird geaendert.
+- `NetzfahrplanAktiv` bedeutet weiterhin den alten Regler. Bei vorhandener V4-Konfiguration wird dessen ausgeschalteter Schalter ausgeblendet. Ein eingeschalteter Altregler bleibt zum Ausschalten sichtbar.
+- Nicht auf V4 eingerichtete Installationen behalten den bisherigen Schalter. Diese Aenderung provisioniert keine neue V4-Installation.
+- `PrognoseAktiv` wird nicht zum automatischen V4-Startsignal. Bestehende Aufnahme-/Sender-Properties und die bisherige Laufzeitvariable bleiben erhalten.
+
+## Dateien
+
+- `Manager/form.json`: stabiler Anker fuer den bestehenden Prognosebereich.
+- `Manager/module.php`: Formularintegration und gepruefter Bedienaufruf.
+- `libs/ManagerPrognoseFormular.php`: reine Formularzusammenstellung ohne I/O.
+- `libs/ManagerNetzfahrplanV4EmpfangTrait.php`: nur bisherigen Formulargenerator entfernt; Empfangscode unveraendert.
+- `tests/PrognoseFormular/`: Formular- und echte RequestAction-Pruefungen mit simulierten IPS-/Stellaufrufen.
+- `tests/V4Receiver/receiver_checks.php`: Strukturpruefung an die zusammengefuehrte Oberflaeche angepasst.
+
+## Tests
+
+Isoliert im PHP-8.3.6-CLI auf einer Quellkopie, nicht im Symcon-Kernel:
+
+| Suite | Erfolgreiche Pruefungen |
+|---|---:|
+| PrognoseFormular/checks.php | 59 |
+| PrognoseFormular/manager_checks.php | 26 |
+| V4Receiver/receiver_checks.php | 32 |
+| V4ControlTrial/checks.php | 96 |
+| V4Feedback/receiver_checks.php | 8 |
+| V4Feedback/device_read_checks.php | 9 |
+| V4ControlTrial/register_checks.php | 1 |
+| Gesamt | 231 |
+
+Zusaetzliche Gesamttests des zusammengefuehrten Stands am 06.10.2026:
+
+- PHP 8.3.6 / PHPUnit 9.6.36: 357 Tests, 1758 Assertions erfolgreich.
+- Syntaxpruefung: alle 150 PHP-Dateien erfolgreich.
+- Backend: 310 Python-Tests erfolgreich mit den vorhandenen QA-Abhaengigkeiten.
+- Portal: 16 Node-Tests erfolgreich.
+- Konfliktmarker- und Patch-Pruefung erfolgreich.
+
+Die Pruefungen liefen in isolierten Quellkopien. Die PHP-Laufzeit wurde nur im
+Agent-Arbeitsordner entpackt, ohne Systeminstallation. Kein Symcon-Kernel-/GUI-
+oder Hardwaretest; der vorhandene Docker-Zugang war nicht nutzbar.
+
+Eine vorbestehende, nicht committe Aenderung an measurement_pipeline.py wurde
+bewusst nicht uebernommen: Sie erzeugte fuer jede konfigurierte Messgrenze ein
+accountingEvidenceId trotz measurementBoundaryVerified=false und verletzte den
+bestehenden Backendtest. Die Datei bleibt im Integrationsstand bytegleich zum
+bisherigen versionierten V4-Stand. Die fremde Arbeitskopie und das laufende
+Backend wurden nicht veraendert. Eine spaetere Freigabe dieser Messgrenze braucht
+einen eigenstaendigen fachlichen Nachweis, keine Anpassung des Tests an das Label.
+
+## Offener Abschluss
+
+Der Auftrag ist mit dieser Bedienintegration noch nicht vollstaendig umgesetzt:
+
+- Die dokumentierte Batterietimerblockade und die fehlende Anlagenabnahme werden hier nicht behoben.
+- Ein regulaerer, lizenzierter Dauerbetrieb anstelle des begrenzten Testpfads ist nicht implementiert.
+- Die separaten Laufzeitvariablen und Diagnoseordner werden noch nicht entfernt oder ausgeblendet.
+- In gespeicherten Settings vom 06.10.2026, 13:06:07 UTC sind nur die Kategorien 21196 (`ENELIX_V4_SEPARATED_OBSERVATION`) und 57590 (`ENELIX_V4_PASSIVE_CAPTURE`) eindeutig als V4-Diagnosebereiche erkannt. Darin liegen weiterhin Beobachtungs-/Aufnahmeskripte. Keine pauschale Loeschung nach Namen.
+- Der allgemeine `Testordner` 10249 enthaelt auch Abrechnung, Schnittstellen und weitere nicht zu dieser Integration gehoerende Objekte. Er bleibt unangetastet.
+- Vor einem Rollout aktuelle Moduldateien sichern, mit dem getesteten Stand vergleichen und Abhaengigkeiten pruefen. Keine pauschalen Modulupdates, Reloads oder Dienstneustarts aus diesem Dokument ableiten.
+- Die Divergenz wurde in einem separaten develop-Checkout auf ubuntu zusammengefuehrt: Server-89-Historie bis ce525a1 und origin/develop bis 5437f3f. Die Originalarbeitsverzeichnisse mit fremden Aenderungen bleiben erhalten. Daniel hat Merge, Commit und Push auf develop und beta ausdruecklich freigegeben; main bleibt unveraendert.
+
+## Uebergabe und Ruecksetzung
+
+Die fruehere Einzelpatch-Uebergabe ist durch den zusammengefuehrten Quellstand
+ersetzt. Die Ausgangshistorie und die zugehoerigen lokalen V4-Quellen sind unter
+/srv/agent/prognose-integration-20261006 gesichert. Der gepruefte Kandidat
+enthaelt keine temporaren Live-Hooks, Zugangsdaten oder fremden uncommitteten
+Ladestationsaenderungen. Ruecksetzungen nur additiv nach Driftpruefung; keine
+fremden Aenderungen verwerfen. Fuer einen spaeteren Runtime-Rollout sind eine
+eigene Sicherung, Abhaengigkeitspruefung und Anlagenabnahme erforderlich.
+
+## Vorschlag PR-Text
+
+**Titel:** Manager: Prognosebedienung im bestehenden Forecast-Bereich buendeln
+
+**Aenderung:** Separaten V4-Formularbereich entfernen, bestehende Funktionen
+unter Prognose / Forecast anbieten und explizite Bedienaktionen zusaetzlich
+gegen Lizenz-, Konfigurations- und Freigabestatus pruefen.
+
+**Unveraendert:** Prognose-/Optimierungsbackend, Empfangsprotokoll, Anlagenlimits,
+befristete Testfreigaben, Datenhistorie und SDL. Keine automatische Aktivierung.
+
+**Pruefung:** 357 PHPUnit-Tests, 310 Backend-Tests, 16 Portal-Tests sowie die
+oben genannten isolierten Bedien-/V4-Checks; kein Hardware- oder Symcon-GUI-Abnahmetest.

+# V4: separate Wirkenergie-Bezugsquelle (Entwicklung, nicht live)
+
+## Lihrenmoos - Befund und geplante Zuordnung
+
+User hat die erfolgreiche Aktivierung der T2-Zaehlerarchivierung fuer 26620
+im Archiv 16207 bestaetigt. Der exakte Beginn einer lueckenlosen Messhistorie
+ist daraus NICHT nachgewiesen; keine historische Null setzen.
+
+Die vorbereitete separate V4-Konfiguration fuer diese Anlage lautet:
+
+```json
+[
+  {"VariableID":59607,"ElternID":11490,"Ident":"Energy_0","FaktorZuKWh":1.0,"Messgroesse":"WirkenergieBezug"},
+  {"VariableID":26620,"ElternID":11490,"Ident":"Energy_1","FaktorZuKWh":1.0,"Messgroesse":"WirkenergieBezug"}
+]
+```
+
+Property: NetzfahrplanV4BezugszaehlerQuellen. Diese Datei setzt KEINE Property.
+IDs duerfen nicht fuer andere Anlagen kopiert werden. Zuordnung ist durch
+Variablenstruktur, Standardtelegramm und Leistungs-/Energiedifferenz stark
+plausibilisiert; Abgleich mit Rohtelegramm/Zaehleranzeige steht noch aus.
+
+53476, dessen gespeicherte Historie, die alte Manager-Property
+NetzbezugEnergieVariableID und alle vorhandenen Spiegelereignisse bleiben
+unveraendert. V4 liest seine eigenen Quellen, erzeugt keine Spruenge in alten
+Summenzaehlern und kann keine Blindenergie durch einen Faktor korrigieren.
+
+## Vertrag
+
+Jede Quelle hat eine ausdrueckliche Messgroesse und Umrechnung nach kWh.
+Variable, Elterninstanz und Ident werden bei jedem Lesen geprueft. Ein
+fehlender, veralteter, ungueltiger oder zeitlich unpassender Teilwert verwirft
+die Summe. Ein aktueller echter Nullwert ist gueltig. Zwei aufeinanderfolgende
+Lesevorgaenge reduzieren das Risiko einer gemischten Momentaufnahme; sie sind
+kein atomarer Zugriff auf das physische Zaehlertelegramm.
+
+Die Summe wird unter bezugszaehler in der lokalen V4-Diagnose ausgegeben, mit
+den Beobachtungszeitpunkten jedes Teilregisters. VariableUpdated ist ein
+Symcon-Aktualisierungszeitpunkt, kein Beweis einer exakten Abrechnungsgrenze.
+Die Diagnose hat deshalb billingEvidence=false und historyComplete=false.
+Eine falsche Messgroessen-Deklaration kann ohne Rohtelegramm nicht automatisch
+erkannt werden; Installationspruefung bleibt erforderlich.
+
+Ein aus Quell-IDs, Eltern-ID, Idents und Umrechnungsfaktoren gebildeter
+stabiler SHA256-Schluessel bindet die spaeteren Messnachweise an genau diese
+Quelle. Die Reihenfolge von T1/T2 aendert den Schluessel nicht. Quell-/Faktor-
+wechsel dagegen invalidieren alte Nachweise. symcon:53476 wird nicht mehr
+als V4-Messnachweis akzeptiert. Der Schluessel beweist Zuordnung, nicht den
+Wahrheitsgehalt eines gelieferten Monatspeaks.
+
+## Noch offen
+
+Der Erzeuger fuer exakte Viertelstundenenergie und den vollstaendigen
+Monatspeak ist weiterhin nicht implementiert. Keine Ableitung eines bereits
+bezahlten Monatspeaks aus einer Managergrenze oder unvollstaendiger Historie.
+Auch 15 Minuten neuer Aufzeichnung beweisen nicht den bisherigen Monatspeak.
+Die vorbereitete native Summe ist noch nicht im laufenden Symcon installiert.
+V4 bleibt ohne belastbare Nachweise in awaiting_inputs.
+
+## Nachweis dieses Schritts
+
+44 synthetische Offline-Szenarien mit PHP CLI 8.4.23 erfolgreich:
+20 Quellen-/Summenpruefungen, 24 native Betriebsdatenkonvertierungen.
+Die vom Server exportierten Betriebsdaten-, Trait- und Fixture-Dateien wurden
+vor dem Test per SHA256 verglichen. Keine Symcon-Laufzeitpruefung und keine
+neue Zielcontainer-/vollstaendige PHPUnit-Pruefung in diesem Schritt.

+# V4: native Betriebsdaten, ausschliesslich Schattenbetrieb
+
+Stand 2026-10-01: Der optionale Sender und die Diagnose sind implementiert.
+Kein V4-Plan wird damit uebernommen, kein Aktor geschrieben, kein V1-Sollwert
+geaendert. Der Sender ist nach Installation standardmaessig AUS.
+
+## Konfiguration im Manager
+
+- NetzfahrplanV4SchattenAktiv: bool, Standard false. Eigener 60-s-Timer,
+  unabhaengig vom bestehenden Prognose-Timer. Fehler betreffen nur den Sendestatus.
+- NetzfahrplanV4NetzladenErlaubt: bool, Standard false. Betrifft ausschliesslich
+  die im Schattenplan angenommene Berechtigung, keine reale Netzladefreigabe.
+- NetzfahrplanV4BatterieOptionen: JSON-Objekt je Topologie-ID. Optional
+  SOCKapazitaet_kWh und MaxSOC_Prozent (sonst 100). Bei unterschiedlicher Nenn-
+  und Nutzkapazitaet ist SOCKapazitaet_kWh zwingend explizit anzugeben.
+- NetzfahrplanV4BezugszaehlerQuellen: JSON-Liste, Standard []. Eigene, explizite
+  Wirkenergie-Bezugsquellen fuer V4; KEIN Rueckfall auf den Altzaehler.
+  Details und Lihrenmoos-Kandidat: Netzfahrplan-V4-Bezugszaehler.md.
+- NetzfahrplanV4MessnachweisVariableID: JSON-Stringvariable, Standard 0.
+  Ein vollstaendiger historischer/registerbasierter Messnachweis-Produzent
+  ist NOCH NICHT integriert. Fehlende Nachweise bleiben fehlend.
+
+Die Quelle muss der gemeinsame Netzanschluss sein. Topologiebatterien werden
+nur einer eindeutigen aktiven Batterieinstanz mit derselben SOC- UND
+Leistungsmessquelle zugeordnet. Externe SDL-Batterien werden nicht automatisch
+hinzugefuegt. SDL-/Grundlastbereinigung bleibt eine separate, noch offene Aufgabe.
+BMS-Grenzen werden mit Topologieleistungen begrenzt. Normale Betriebsreserve
+und technisches Minimum werden nicht verwechselt: die hoehere Grenze gilt.
+
+Der erweiterte Sender uebermittelt Entladesperre und Wiederfreigabe-SOC separat
+von der maximalen Entladeleistung. Der neue Python-Rechenkern darf die Sperre
+im Zukunftsplan erst nach vorherigem Laden bis zur Wiederfreigabe aufheben.
+SOC unterhalb der Betriebsreserve, aber oberhalb des technischen Minimums,
+bleibt unveraendert erhalten: Es ist Wiederaufladung statt erfundener Energie
+vorgesehen. Unterhalb des technischen Minimums wird kein normaler Plan erzeugt.
+
+Zusaetzlich wird meterObservation mit frischen Empfangswerten der Netzleistung
+und T1/T2-Summe uebermittelt. Dessen laufende Viertelstundenintegration ist eine
+explizite Planungsschaetzung, KEIN verifizierter Abrechnungsnachweis. Verwendung
+von Schaetzungen muss im V4-Dienst ausdruecklich aktiviert werden. Historische
+Peakannahmen werden getrennt von verifizierten Maxima gespeichert.
+
+Diese Protokollerweiterung benoetigt zuerst den passenden Backendstand. Der
+bisherige laufende V4-Container und die Testanlage sind noch nicht aktualisiert.
+Offline-Szenarien und Quelltextpruefungen ersetzen keinen Symcon-Laufzeittest.
+
+## Diagnose ohne Netzwerk oder Stellbefehl
+
+Im Symcon-Skript nach Installation des neuen Modulstands:
+
+```php
+<?php
+print_r(json_decode(ENELIX_GetNetzfahrplanV4Diagnose(17004), true));
+echo ENELIX_GetNetzfahrplanV4Sendestatus(17004);
+```
+
+Die Diagnose enthaelt KEINE Tokens oder sonstigen Zugangsdaten. Sie ist auch
+bei ausgeschaltetem Sender verfuegbar. Die Instanz-ID ist fuer Lihrenmoos aus
+der bestehenden Konfiguration bekannt, nicht fuer andere Anlagen zu kopieren.
+Nicht ungeprueft deployen: Host-CLI- und Zielsystemtests getrennt nachweisen.
+
+## Messnachweis-Vertrag (Beispiel, KEINE realen Messwerte)
+
+```json
+{
+  "version": 1,
+  "meterId": "symcon-active-import:<SHA256-der-konfigurierten-Quellen>",
+  "measuredAt": "2026-10-01T12:05:00Z",
+  "measuredPeaks": {
+    "2026-10": {"kw": 18.4, "source": "meter_month_register"}
+  },
+  "quarterPast": {
+    "start": "2026-10-01T12:00:00Z",
+    "measuredSeconds": 300,
+    "importKwh": 0.5
+  }
+}
+```
+
+Zulaessige Herkunft: meter_month_register, verified_month_history oder
+verified_new_month. Der Nachweis-Produzent muss deren Wahrheit garantieren.
+Managergrenzen sind NIE ein gemessener Monatspeak. Der Monatswert muss den
+vollstaendigen bisherigen Abrechnungsmonat abdecken. Fuer quarterPast muessen
+Zaehlerzeitpunkt, abgedeckte Sekunden und Entscheidungszeitpunkt exakt passen;
+veraltete Energie wird nicht hochgerechnet oder als aktuelle Messung ausgegeben.
+Die kumulative kWh-Variable allein erfuellt diesen Vertrag noch nicht.
+
+Die V4-API meldet bei fehlendem Monatspeak/quarterPast weiterhin awaiting_inputs.
+Ein HTTP stored bestaetigt nur den Eingang der Telemetrie, nicht einen gueltigen
+Fahrplan und schon gar nicht dessen Ausfuehrung. Backend und Portal-Bruecke
+muessen separat aktiviert werden. Keine neue Modellwahl oder Aktorfreigabe hier.
+
+## Tests
+
+24 offline Konvertierungsszenarien und 20 Quellen-/Summen-Szenarien sowie PHPUnit-Strukturpruefungen. Werte sind
+synthetisch; keine reale HTTP-Anbindung oder Symcon-Laufzeit damit behauptet.

+# V4 confirmed feedback for Lihrenmoos
+
+This incremental package adds synchronous device reads before V4 feedback is evaluated.
+
+- Grid input 40348 is refreshed through its M-Bus device.
+- GoodWe and SolarEdge inputs are refreshed through their ModBus parent instances.
+- A successful driver call is required; cached variable timestamps alone are not accepted.
+- Daniel Haefliger accepted the existing `virtual_split` model for the bounded field test on 2026-10-04.
+- The installer keeps the legacy schedule and both V4 trial permissions disabled.
+- A real control trial still requires separate server authorization and evidence of an independent device-side watchdog.
+
+Build a private staging directory:
+
+```sh
+python3 examples/V4ConfirmedFeedback/build_stage.py /srv/agent/netplan-v4-confirmed-feedback
+```
+
+Run the staged PHP checks before copying the package to the test plant. Execute `install.php` only from the IP-Symcon script editor on Lihrenmoos.

+# Integrated application data/model path - 2026-10-02
+
+User request: finish application implementation, stop asking for repeated hardware
+confirmations and adding standalone diagnostic samplers. No actuator permission is
+implied by that development request. Confirmed EV allocation remains 161.44 kWh /
+39 kW each direction, with SDL reserve already excluded.
+
+## Implemented in the existing application
+
+- Native ManagerNetzfahrplanV4DatenTrait: 30-second acquisition of configured numeric
+  sources; durable private app-owned outbox; original timestamps, no new Modbus
+  polls; acknowledged per-plant batches with retries/backoff. Cursor advances only
+  after exact dataset/acceptedThrough acknowledgement. Batches bounded below the
+  existing portal's 1 MiB body limit. No credentials in data payload or reports.
+- Existing device proxy now forwards /planner-v4/measurements through the existing
+  authentication, plant binding, licence check and separate V4 rate limiter.
+  Device route cannot modify the dataset mapping or issue a trial grant.
+- Existing V4 database stores immutable versioned source mappings and observations.
+  Same-time conflicts reject the whole batch; repeated identical data is idempotent.
+  No writes to portal/users/legacy measurement databases.
+- Existing V4 worker aggregates physical load using original source times. Virtual
+  EV/SDL filter outputs are not load inputs. Solar terminal variant counts signed
+  terminal power once. Small unobserved parts remain quantified, never zero-filled.
+  This configured formula remains an estimate, not independent AC/DC certification.
+- Application profile training actually runs daily/weekly. Models are immutable,
+  bootstrap/holdout status explicit. Incumbent replacement requires a causal
+  holdout when available. Existing data and model versions are not relabelled.
+- Three corrected load variants (daily robust profile, last-day profile,
+  weekday/weekend profile) are paired with the existing PV families 3/13/23.
+  They are tagged physical-profile-v1; they are NOT claimed to be the old trained
+  load algorithms under a new data name. Automatic future family registry work
+  and economic replay are still distinct from this load-profile implementation.
+- Selecting corrected_profile in the existing GUI/setting now actually changes
+  the load entering the existing optimizer. Missing trained data cannot silently
+  fall back to the contaminated legacy household series.
+- A current SDL request is an explicitly labelled PERSISTENCE SCENARIO for the
+  shadow economic calculation, not a published future schedule. Missing/stale SDL
+  is not zero. This is not a robust/full SDL production-dispatch policy.
+- GUI now exposes dataset/source selection, records, usable equivalent hours,
+  model version, validation and real training cadence. Existing normal portal
+  app.js/index files are not changed.
+
+## Deployment package
+
+Server: commissioning/deploy_application.py --plant <approved UUID> --apply
+Rebuild/test V4 with Python 3.11, portal routing tests, consistent SQLite backup,
+replace ONLY V4 and portal, configure the new per-plant dataset. No automatic
+forecast-source switch and no control grant. Atomic file-bind replacement requires
+portal recreation, not a simple restart. Additive DB rollback retains new data.
+Default invocation without --apply validates source manifests only.
+
+Test host: /srv/agent/netplan-v4-application-build/install.php inside Symcon.
+Installs a DATA-ONLY patch of the currently installed passive manager (not the
+unreleased controller-trial candidate), reloads EMS, configures acquisition and
+imports up to 48h of the existing 23-source observer as a delivery backlog.
+Original observer and old raw journals remain intact. Existing separate observers
+are NOT automatically stopped by this initial installer; consolidation should
+follow confirmed native batch acceptance. No new root diagnostic category.
+An asynchronous module registration may require one repeat, handled explicitly.
+
+Dataset lihrenmoos-physical-v1: minimum coverage 95%, longest unsupported portion
+10s, at least 24 equivalent usable hours, 28-day profile history. The 95% rule is
+an explicit modelling policy, not a statement that missing energy was measured.
+Insufficient data remains collecting; no promised time to good forecasts.
+All original acquisition thresholds remain unchanged.
+
+## Tests and honest limits
+
+Host tests use existing isolated QA dependencies; native tests mock IPS/HTTP and
+use temporary files. Real container and kernel tests occur on the user-run deploy
+commands, not during preparation. No services/modules/settings/devices were modified
+by this development session.
+
+Still NOT a complete production commissioning: the corrected profile-to-local
+feedback/dispatch integration, full automatic cost replay, independent long-term
+outbox/server retention and staged live/failure acceptance remain open. The trial
+code from previous commits remains gated and is not included in the data-only
+native installation. No accountingEvidenceId/device watchdog proof is fabricated.
+This release is an integrated application build, NOT a claim that the full original
+multi-plant production scope is done. No main/beta release is authorized by tests alone.
