+# OCSentinel Beta Deployment
+
+## Ziel
+
+Beta-Pakete werden ausschliesslich an benannte Pilotgeraete verteilt. Der
+Stable-Kanal und die vorhandene Stable-NinjaOne-Aufgabe bleiben unveraendert.
+
+## Beta-Aufgabe in NinjaOne
+
+1. Die bestehende Aufgabe `OCSentinel - Installieren und aktualisieren`
+   duplizieren und eindeutig als `OCSentinel - Beta Pilot` benennen.
+2. Das Script `scripts/bootstrap-ocsentinel-ninja.ps1` verwenden.
+3. Die Script-Variable `releasechannel` als Text mit dem Wert `beta` anlegen.
+4. Webhook und Secret bleiben identisch zum Stable-Task.
+5. Die Aufgabe nur einer Pilot-Richtlinie oder explizit ausgewaehlten Geraeten
+   zuweisen.
+
+Die Stable-Aufgabe verwendet keinen Kanalwert oder den Wert `stable`.
+
+## Passive Ransomware-Beta
+
+Die Beta ist nach der Installation weiterhin deaktiviert. Auf einem
+Pilotgeraet wird in `C:\Program Files\OCSentinel\config\ocsentinel-settings.json`
+der Wert `ransomwareBetaEnabled` auf `true` gesetzt. Die Auswertung bleibt
+passiv, solange `ransomwareBetaAlertingEnabled` auf `false` steht: Hinweise,
+Warnungen und kritische Beta-Signale erscheinen im JSON-Report und Dashboard,
+veraendern aber keine NinjaOne-Alarmfelder.
+
+Der optionale Datei-Churn-Sensor wird nur mit
+`ransomwareFileChurnEnabled: true` aktiviert. Er wertet ausschliesslich bereits
+vorhandene Security-Ereignisse 4663 aus, setzt keine Audit-Richtlinie und
+aendert keine SACLs. Es werden nur Zaehler sowie Prozessnamen gespeichert und
+uebertragen, niemals Datei- oder Freigabenamen. Eine Auswertung ist auf 5.000
+Audit-Ereignisse und ein 15-Minuten-Fenster begrenzt; ein gekappter Lauf erzeugt
+kein Churn-Signal.
+
+## Rueckfall
+
+1. Die Beta-Richtlinie entfernen oder die Beta-Aufgabe nicht mehr ausfuehren.
+2. Auf den Pilotgeraeten die vorhandene Stable-Aufgabe ausfuehren.
+3. Die Ransomware-Beta in der lokalen Konfiguration auf `false` setzen, falls
+   sie aktiviert wurde.
+
+Der Client prueft weiterhin Paket-Hash und Authenticode-Signaturstatus, bevor
+eine Beta installiert wird.
+
+## Pilotprotokoll
+
+Vor dem Start festhalten: Organisation, Geraete, Aktivierungszeit, aktivierte
+Feature-Schalter, verantwortliche Person und geplantes Enddatum. Nach dem
+Pilot Laufzeit, Upload-Volumen, Hinweise und Fehlalarme bewerten.

+
+## Ziel
+
+Der Client soll klein, pruefbar und wartbar bleiben. Kommentare sind keine
+zweite Dokumentation und keine Erklaerung fuer selbsterklaerenden Code.
+
+## Kommentarregel
+
+- Kommentare bleiben nur bei Sicherheitsgrenzen, externen API-Eigenheiten,
+  nicht offensichtlichen Entscheidungen und bewusstem Fehlertoleranz-Verhalten.
+- Beschreibende Kommentare direkt neben selbsterklaerenden Anweisungen werden
+  entfernt.
+- Veraltete Kommentare werden im selben Pull Request wie die Codeaenderung
+  geloescht oder aktualisiert.
+- Architektur- und Betriebswissen gehoert in `docs`, nicht in lange
+  Quellcodekommentare.
+
+## Wiederkehrender Clean-up
+
+Bei jeder Minor-Version wird ein kurzer Wartungsdurchlauf eingeplant:
+
+1. Tote Konfiguration, nicht erreichbare Pfade und doppelte Hilfsfunktionen entfernen.
+2. Kommentare gegen den aktuellen Code pruefen und ueberfluessige entfernen.
+3. Formatierung und Benennung vereinheitlichen.
+4. Release-Build und die relevanten Scan-Szenarien erneut ausfuehren.
+
+## Sicherheitsausnahme
+
+Kommentare, die vor einer unsicheren Aenderung schuetzen, bleiben erhalten.
+Beispiele sind TLS-Kompatibilitaet, Secret-Schutz, Upload-Signaturpruefung und
+deterministische Lastverteilung.

+## Local Schedule And Burst Mode
+
+During a NinjaOne installation or update, OCSentinel stores the device's
+NinjaOne organization, location, and device identifiers in its local client
+configuration. Scheduled `SYSTEM` scans restore that context before creating a
+report, so their uploads remain assigned to the correct organization.
+
+The installer creates two Windows Scheduled Tasks running as `SYSTEM`:
+
+- `OCSentinel Daily Scan`: runs once per day and uploads one signed report.
+  The installer deterministically assigns each device a stable slot between
+  `04:00` and `06:59`, derived from its Windows `MachineGuid`. This distributes
+  a fleet rollout instead of sending all reports at the same time.
+- `OCSentinel Burst Check`: runs every five minutes. It performs no scan unless
+  the NinjaOne device custom field `ocsentinelburst` is enabled. Once enabled,
+  it scans for two hours and then disables itself automatically.
+
+Create `ocsentinelburst` as a device-level `Checkbox` custom field and allow
+automation read and write access. Set it to `true` for a device to begin the
+five-minute burst scans; clear it to stop them early. The normal daily scan
+continues regardless of the checkbox.
+
+Create these accompanying device custom fields and allow automation write
+access:
+
+| Field name | Type | Purpose |
+| --- | --- | --- |
+| `ocsentinelburstuntilutc` | Date/Time | UTC time at which the active burst ends |
+| `ocsentinelburststatus` | Text | `idle`, `active until ...`, or `completed` |
+
+## Upload Reliability And Client Health
+
+If the upload endpoint is temporarily unavailable, the client stores up to 100
+signed report payloads locally under `C:\ProgramData\OCSentinel\upload-queue`.
+The next scheduled run sends queued payloads before its new report. The local
+health state is stored under `C:\ProgramData\OCSentinel\state`.
+
+Create these additional device custom fields in NinjaOne and allow automation
+write access:
+
+| Field name | Type | Purpose |
+| --- | --- | --- |
+| `ocsentineluploadstatus` | Text | `ok`, `queued`, or `unknown` upload state |
+| `ocsentinelqueuedreports` | Integer | Reports waiting for delivery |
+| `ocsentinellastuploadutc` | Date/Time | Last successful upload time |
+| `ocsentinellasterror` | Text | Last upload error, if any |
+| `ocsentinelclientversion` | Text | Installed client version |
+
 ## NinjaOne Tasks
 
-Initial install/update:
+Create a PowerShell script in NinjaOne named `OCSentinel - Installieren oder aktualisieren`.
+Run it as `SYSTEM` in 64-bit PowerShell and copy the content of
+`scripts/bootstrap-ocsentinel-ninja.ps1` into the NinjaOne script editor.
+It is idempotent: new devices install the current package, while installed devices
+only update when a newer manifest version is published.
+
+Use it for the one-time rollout and, later, as the monthly update task. For an
+initial validation scan, add `-RunInitialStatusScan` to the script parameters.

+persisted during an actual NinjaOne automation.
+
+If the console shows `Organisation unbekannt`, create a temporary NinjaOne
+PowerShell automation named `OCSentinel - NinjaOne Kontext aktualisieren` and
+copy `scripts/refresh-ocsentinel-ninja-context.ps1` into the editor. Run it as
+`SYSTEM` in 64-bit PowerShell once against the affected devices or policy.
+
+The script has no script variables and does the following safely:
+
+1. updates the installed client through the stable, version-independent manifest;
+2. stores the current NinjaOne organization, location, node, and machine values;
+3. starts one signed status scan and upload using that stored context.
+
+Expected output includes `OCSENTINEL_NINJA_CONTEXT=updated`; this is emitted
+only after the immediate upload succeeds. Do not run this script from an
+interactive PowerShell session, because NinjaOne does not expose the required
+environment values there.

+## Development Upload
+
+For the internal development environment, copy
+`config/ocsentinel-client.dev.example.json` to the installed client config
+path and use its HTTP webhook URL. Production clients must use the HTTPS
+configuration with the public Sentinel domain instead.
+
+## Current Manual Release State
+
+As of July 16, 2026, the first manual release is already published:
+
+- tag: `v1.2.3`
+- release URL: `https://gitea.officecom.cloud/officecom/oc-sentinel/releases/tag/v1.2.3`
+- stable manifest URL: `https://gitea.officecom.cloud/officecom/oc-sentinel/raw/main/release/stable/version.json`
+
+The manifest is intentionally version-independent for NinjaOne. Only the JSON content changes per release; the NinjaOne task URL stays the same.
+
+This means NinjaOne rollout can start immediately without waiting for a Gitea runner.
+
+## Later Automation
+
+When a Gitea runner is added later, the usual next step is:
+
+1. connect to the runner host through SSH or RDP, depending on the server type
+2. install and register the Gitea runner
+3. let `.gitea/workflows/client-build.yml` publish future release artifacts automatically
+4. update `release/stable/version.json` automatically as part of the release flow

 - storage in the central backend
 - organization-wide aggregation
 - NinjaOne organization API updates
+
+## Required n8n Workflow
+
+The webhook itself may be reachable only on the internal network. It does not
+require public access to the n8n editor or API. Every managed device must be
+able to reach the webhook URL over HTTPS.
+
+For the isolated development environment only, HTTP is permitted at
+`http://172.16.41.197:5678/webhook/ocsentinel-ingest`. Do not reuse this URL,
+the development shared secret, or a disabled-TLS configuration in production.
+
+1. `Webhook`: accept `POST` on the configured private URL and enable **Raw Body**.
+2. `Code`: reject a request if `X-ATN-Device`, `X-ATN-Timestamp`,
+   `X-ATN-Nonce`, `X-ATN-Version`, `X-ATN-Payload-SHA256`, or
+   `X-ATN-Signature` is missing; reject timestamps outside five minutes.
+3. `Code`: calculate SHA-256 over the raw request body and compare it with
+   `X-ATN-Payload-SHA256`. Calculate HMAC-SHA256 over the following exact
+   newline-separated string and compare it in constant time with
+   `X-ATN-Signature`:
+
+```text
+<device>\n<timestamp>\n<nonce>\n<version>\n<payload-sha256>
+```
+
+In the current n8n Webhook node, the raw bytes are exposed as Base64 at
+`$binary.data.data`. Decode this value before calculating the payload hash.
+Do not hash `JSON.stringify($json.body)`: parsing and reserializing JSON
+changes whitespace and can change the signed byte sequence.
+
+4. `Postgres`: insert the nonce into `ocsentinel.ingest_nonce` with a short
+   expiry. If it already exists, return `409` and do not process the report.
+5. `Postgres`: upsert the device, insert a row in `ocsentinel.scan_report`,
+   then return `202`.
+6. A separate scheduled n8n workflow reads
+   `ocsentinel.organization_summary` and `ocsentinel.current_device_status`
+   to update the NinjaOne organization fields through the API.
+
+Use an n8n credential for the shared HMAC secret and a separate n8n credential
+for PostgreSQL. Do not store either value in workflow JSON or this repository.
+For the current Docker deployment, use the private hostname
+`ocsentinel-postgres` and the restricted database role `ocsentinel_n8n`; see
+`infra/dockge/README.md` for the remaining credential fields.
+
+## PostgreSQL Scope
+
+- The client only knows its outward upload destination.
+- PostgreSQL connection details belong to the internal ingest or n8n side.
+- If the PostgreSQL IP changes, update the internal server-side configuration and review it during the next release.

+# Release Checklist
+
+## Goal
+
+Use this checklist before publishing every OfficeCom Sentinel release.
+
+## Infrastructure Check
+
+1. Confirm the internal PostgreSQL target is still correct in `infra/postgres-target.example.json` or its private production counterpart.
+2. Confirm the n8n internal base URL is still correct.
+3. Confirm the public client ingest URL still forwards to the intended internal service.
+4. Confirm no internal PostgreSQL host or IP is embedded in client configuration, installer output, or public release artifacts.
+
+## Build Check
+
+1. Build `OCSentinelClient-win-x64.zip`.
+2. Build `OCSentinelSetup.exe`.
+3. Generate `version.json`.
+4. Verify SHA-256 output matches the released ZIP.
+
+## Publish Check
+
+1. Upload the ZIP, SHA256 file, and setup EXE to the release.
+2. Update `release/stable/version.json` so NinjaOne keeps a version-independent manifest URL.
+3. If infrastructure changed, update the internal Postgres target record in the repo at the same time.

+# OfficeCom Sentinel Roadmap
+
+## Produktziel
+
+OfficeCom Sentinel erkennt nachvollziehbare Sicherheitsmuster auf Windows-
+Endpunkten und Fileservern, ohne den Betrieb zu stoeren. NinjaOne ist fuer
+zeitnahe Alerts zustaendig. Die zentrale Plattform sammelt verdichtete
+Telemetrie, zeigt die Sicherheitslage je Organisation und erstellt Berichte.
+
+Der Client ersetzt weder G DATA/MXDR noch ein EDR. Er ergaenzt diese Systeme mit
+lokaler Korrelation, organisationsuebergreifender Sicht und nachvollziehbaren
+Incident-Protokollen.
+
+## Leitplanken
+
+- Wenige aussagekraeftige Signale statt Alarmierung bei Einzelereignissen.
+- Die Bewertung muss im JSON-Report und in der Uebersicht nachvollziehbar sein.
+- Kein direkter Datenbankzugriff und keine internen Infrastrukturwerte im Client.
+- Standardmaessig minimale Last: keine Vollscans, kein globales Dateiauditing,
+  keine dauerhafte Uebertragung von Rohereignissen.
+- Datenminimierung: zentrale Speicherung nur von verdichteten Ereignissen und
+  Incident-Kontext, nicht von vollstaendigen Dateilisten.
+
+## Beta- und Rollback-Modell
+
+Jede neue Erkennung, Datenart und UI-Aenderung durchlaeuft denselben
+reversiblen Lieferweg. Eine Funktion wird nie erstmals auf dem gesamten Bestand
+aktiv geschaltet.
+
+### Stufe 0: Spezifikation und lokale Tests
+
+- Zweck, Datenfelder, Bewertung und erwartete Last werden vor dem Coding
+  dokumentiert.
+- Beispielereignisse decken Normalfall, Hinweis, Warnung, kritisch und Fehler
+  ab.
+- Der Client muss bei fehlender neuer Konfiguration das bisherige Verhalten
+  unveraendert beibehalten.
+
+### Stufe 1: Interne Beta
+
+- Das Paket wird als separater Beta-Release veroeffentlicht; `stable` bleibt
+  unveraendert.
+- Eine neue Funktion ist per Feature-Schalter standardmaessig deaktiviert.
+- Die Beta wird nur auf Testgeraeten bzw. einer internen Organisation verteilt.
+- Zentrale Auswertung prueft Laufzeit, Upload-Volumen, Fehler und Datenformate.
+
+### Stufe 2: Passiver Kunden-Pilot
+
+- Ausgewaehlte Geraete erhalten die Beta mit aktivierter Funktion im
+  Beobachtungsmodus.
+- Signale erscheinen in Protokoll und Dashboard, loesen aber keine NinjaOne-
+  Alarmbedingung aus.
+- Der Pilot laeuft mindestens eine realistische Arbeitswoche, bei Fileservern
+  inklusive der normalen Spitzenzeiten.
+
+### Stufe 3: Kontrollierte Alarmierung
+
+- Erst nach Auswertung werden Warnungen fuer eine kleine, benannte Pilotgruppe
+  an NinjaOne uebergeben.
+- Hinweise bleiben weiterhin rein informativ.
+- Schwellenwerte, Ausnahmen und Empfaenger werden pro Pilot dokumentiert.
+
+### Stufe 4: Stable-Rollout
+
+- Rollout zuerst je Organisation oder Richtlinie, nicht an alle Kunden zugleich.
+- Der Stable-Kanal wird erst nach erfolgreichem Pilot, Review der Datenqualitaet
+  und Freigabe der Alarmbedingungen aktualisiert.
+- Die vorherige Stable-Version bleibt als signiertes Release verfuegbar.
+
+### Rueckfall
+
+- Sofort: Feature-Schalter in der Richtlinie deaktivieren. Der Client bleibt
+  installiert, sammelt fuer diese Funktion aber nichts mehr.
+- Kurzfristig: Pilotgeraete ueber NinjaOne auf die vorherige Stable-Version
+  zuruecksetzen.
+- Zentral: Die Auswertung kann das neue Feld ignorieren; neue JSON-Felder sind
+  immer optional und muessen abwaertskompatibel bleiben.
+- Datenbankaenderungen werden nur additiv eingefuehrt. Loeschende oder nicht
+  rueckgaengig zu machende Migrationen gehoeren nicht in eine Beta.
+
+### Abbruchkriterien
+
+Ein Pilot wird pausiert und zurueckgesetzt, wenn eines dieser Kriterien eintritt:
+
+- spuerbare Last oder Beeintraechtigung auf einem Kundenserver,
+- unkontrolliertes Upload- oder Queue-Wachstum,
+- fehlerhafte Organisationszuordnung oder unerwartete personenbezogene Daten,
+- mehr als ein unbegruendeter NinjaOne-Alarm im Pilot ohne klare Korrektur,
+- fehlende oder nicht nachvollziehbare Incident-Protokolle.
+
+## Ausgangslage: geliefert
+
+- Endpoint-Client mit signiertem Upload und lokaler NinjaOne-Feldaktualisierung.
+- N8n- und PostgreSQL-Pipeline mit organisationsbezogener Zuordnung.
+- Interne Uebersicht, Empfaengerverwaltung und woechentliche HTML-Berichte.
+- Gestaffelte taegliche Uploads sowie Burst-Pruefung.
+- Version 1.4.0: Fehlanmeldungen werden in 15-Minuten-Fenstern korreliert.
+  Einzelne Tippfehler erzeugen keinen Alarm; Anmelde-Bursts und Password
+  Spraying werden als Warnung oder kritisch bewertet.
+
+## Voraussetzung: 1.4.1 Beta-Auslieferung
+
+- Eigener Beta-Manifest-Pfad neben `release/stable/version.json`.
+- Eigene NinjaOne-Aufgabe fuer Pilotgeraete, die ausschliesslich den
+  Beta-Manifest-Pfad verwendet.
+- Stable-Aufgabe bleibt unveraendert und ist zugleich der schnelle Rollback auf
+  die letzte freigegebene Version.
+- Beta-Releases werden in Gitea als Vorabversion markiert und erhalten dieselbe
+  Paket-Hash-Pruefung wie Stable-Releases.
+- Jeder Pilot dokumentiert Geraete, Organisation, aktivierte Feature-Schalter,
+  Startzeitpunkt und verantwortliche Person.
+
+## Naechster Schwerpunkt: 1.5 Ransomware-Frueherkennung
+
+### 1.5.0: Leichtgewichtiger Fileserver-Sensor
+
+**Lieferumfang**
+
+- Inkrementelle Auswertung statt Dateiscan: Nur neue Prozess- und
+  Systemereignisse sowie Aenderungszaehler seit dem letzten Pruefpunkt.
+- Erkennung hochrelevanter Manipulationen wie Schattenkopie-, Recovery- und
+  Backup-Loeschbefehle sowie verdaechtiger Verschluesselungswerkzeuge.
+- Lokaler Ringpuffer mit aggregierten Datei-Churn-Signalen aus vorhandenen
+  Datei-Audit-Ereignissen. Die erste Beta wertet Loesch- und Schreibzugriffe
+  ohne Datei- oder Freigabenamen aus.
+- Snapshot der SMB-Sitzungen und des Incident-Kontexts erst bei einer
+  Auffaelligkeit.
+- Verdichtetes Ransomware-Incident-Protokoll fuer n8n und die Uebersicht.
+
+**Bewertung**
+
+- Hinweis: Ein schwaches, isoliertes Signal. Es erscheint in Protokoll,
+  Uebersicht und Wochenbericht, aber nicht als NinjaOne-Alarm.
+- Warnung: Zwei unabhaengige Signale innerhalb eines kurzen Zeitfensters oder
+  eine veraenderte Canary-Datei.
+- Kritisch: Mehrere korrelierte Signale oder eine bestaetigte Schutzmeldung von
+  G DATA/MXDR zusammen mit auffaelligem Datei-Churn.
+
+**Last- und Datenschutzgrenzen**
+
+- Sensorpruefung hoechstens einmal pro Minute, ausschliesslich inkrementell.
+- Kein globales Windows-Dateiauditing und keine globale Sysmon-Dateierstellung.
+- Keine Datei-Hashes und keine rekursiven Share-Scans im Normalbetrieb.
+- Maximal ein verdichteter Incident-Upload je Fileserver und fuenf Minuten;
+  gleiche Muster werden lokal zusammengefasst.
+- Keine Dateinamen im Standardprotokoll; optionale, begrenzte Detaildaten nur
+  fuer explizit konfigurierte kritische Freigaben.
+
+**Abnahme**
+
+- Test auf einem produktionsnahen Fileserver mit normaler Benutzerlast.
+- Vergleich der Sensorlast vor und nach Aktivierung.
+- Nachweis, dass normale Dateiaktivitaet von vielen Benutzern keinen Alert
+  erzeugt und ein simuliertes Mehrsignal-Szenario korrekt eskaliert.
+- Offline-Pufferung, Deduplizierung und Retry des Incident-Protokolls getestet.
+- Start als interne Beta gemaess dem Beta- und Rollback-Modell; der Sensor wird
+  erst nach dem passiven Fileserver-Pilot als NinjaOne-Alarm aktiviert.
+
+### 1.5.1: Tuning und kontrollierter Rollout
+
+- Baseline je Fileserver und Zeitfenster aus mindestens einer Arbeitswoche.
+- Konfigurierbare Ausnahmen fuer bekannte Backup-, Scan- und Servicekonten.
+- Pilotgruppe mit wenigen Fileservern, Auswertung der Hinweise und Anpassung
+  der Schwellenwerte vor breiter Verteilung.
+- Klare NinjaOne-Conditions fuer Warnung und kritisch; Hinweise bleiben ohne
+  Ticket- oder Alarmflut.
+
+## Danach: 1.6 Zusaetzliche Sensoren
+
+- Neue lokale Administratoren und auffaellige Gruppenmitgliedschaften.
+- RDP- und SMB-Fehlanmeldungen mit Quell- und Konto-Korrelation.
+- Sicherheitsrelevante Aenderungen an Diensten, geplanten Aufgaben und
+  Autostart-Mechanismen.
+- Optionaler Import von G DATA-/MXDR-relevanten lokalen Ereignissen, sofern
+  diese verlaesslich und ohne proprietaere Nebenlast verfuegbar sind.
+
+## Danach: 1.7 Modernes Web GUI und Visualisierung
+
+Das interne Web GUI wird von einer Debug-Ansicht zu einer schnellen,
+arbeitsfaehigen Sicherheitsuebersicht weiterentwickelt. Es bleibt intern und
+benoetigt keine eigene Anmeldung, solange der Zugriff ueber das bestehende
+interne Netz und den Reverse Proxy abgesichert ist.
+
+### Informationsarchitektur
+
+- Startseite mit Sicherheitslage ueber alle Organisationen, aktiven Incidents,
+  Datenabdeckung und Upload-Gesundheit.
+- Organisationsansicht mit Trend, betroffenen Geraeten, offenen Hinweisen und
+  letzter erfolgreicher Datenerfassung.
+- Geraeteansicht mit klarer Risikozusammenfassung, Ereignis-Timeline,
+  Ransomware-Incident-Protokollen und aufgeklapptem Rohdatenexport fuer die
+  technische Analyse.
+- Berichtsbereich mit Vorschau, Versandstatus, Empfaengerregeln und erneutem
+  Versand einer Organisation.
+
+### Visualisierung
+
+- Zeitreihe fuer Hinweise, Warnungen und kritische Signale je Organisation.
+- Gestapelte Tagesansicht fuer Login-, CVE-, Ransomware- und Sensor-Signale.
+- Heatmap fuer auffaellige Zeitfenster statt einer langen, schwer lesbaren
+  Ereignisliste.
+- Abdeckungsansicht: aktive Clients, veraltete Scans, Upload-Fehler und
+  Geraete ohne Organisationszuordnung.
+- Jede Grafik verweist auf die zugrundeliegenden Geraete und Ereignisse; es
+  gibt keine rein dekorativen Kennzahlen ohne Drill-down.
+
+### Technische Leitplanken
+
+- Responsive fuer Notebook, Tablet und Mobilansicht; barrierearme Kontraste und
+  klare Statusfarben.
+- Datenbankabfragen liefern aggregierte Zeitreihen. Rohdaten werden nur beim
+  Oeffnen einer Geraete- oder Incident-Ansicht nachgeladen.
+- Begrenzte Zeitraeume und serverseitige Pagination verhindern langsame Seiten
+  bei wachsendem Datenbestand.
+- HTML-E-Mails und Weboberflaeche teilen einen konsistenten visuellen Standard,
+  aber keine fragilen, kopierten CSS-Regeln.
+
+### Beta und Abnahme
+
+- Neue GUI zunaechst unter separatem internen Beta-Pfad neben der bestehenden
+  Uebersicht bereitstellen.
+- Vergleich der neuen Kennzahlen mit den bekannten Rohdaten und Wochenberichten.
+- Pilot mit realen Organisationen, insbesondere einer groesseren Fileserver-
+  Umgebung, vor Umschalten der Standardansicht.
+- Zuruecksetzen erfolgt ueber den Reverse Proxy auf die bestehende GUI; Daten
+  und Empfaengerregeln bleiben dabei unveraendert.
+
+## Danach: 1.8 Betrieb und Auswertung
+
+- Datenqualitaetspruefung fuer unbekannte Organisationen, fehlende Zuordnung
+  und veraltete Clients.
+- Sensor- und Client-Gesundheit in der internen Uebersicht.
+- Berichtsvarianten je Empfaengergruppe und nachvollziehbare Versandhistorie.
+- Betriebsmetriken fuer Upload-Fehler, Queue-Alter und Incident-Volumen.
+
+## Nicht Bestandteil
+
+- Kein zweiter Antivirus- oder EDR-Agent.
+- Keine Blockierung oder automatische Wiederherstellung durch OCSentinel ohne
+  explizite, separat freigegebene Schutzfunktion.
+- Kein zentraler Upload aller Dateioperationen oder kompletter Eventlogs.
+
+## Qualitaet in jedem Release
+
+- Keine neue Erkennung ohne Beispielereignisse, Regressionstest und dokumentierte
+  Bewertungslogik.
+- Jede neue Datenart benoetigt Zweck, Aufbewahrungsregel und Datenschutzpruefung.
+- Vor jeder Minor-Version: Code-Clean-up, Abhaengigkeiten pruefen, tote Pfade
+  entfernen, ueberfluessige Kommentare loeschen und Dokumentation aktualisieren.
+- Release erst nach Build, Paket-Hash-Pruefung und einem Test der Update- und
+  Upload-Strecke.

+# OCSentinel PostgreSQL Dockge Stack
+
+Production is deployed as the Dockge stack directory:
+
+```text
+/dockerstacks/ocsentinel-postgres
+```
+
+The stack runs `postgres:16-alpine` as `ocsentinel-postgres` and joins the
+existing Docker network `n8n_n8n-network`. It deliberately has no `ports:`
+mapping, so PostgreSQL is not exposed on the host network or the Internet.
+
+The stack owns these private files on the server:
+
+```text
+/dockerstacks/ocsentinel-postgres/compose.yaml
+/dockerstacks/ocsentinel-postgres/.env
+/dockerstacks/ocsentinel-postgres/init/
+/dockerstacks/ocsentinel-postgres/data/
+```
+
+`.env` is root-readable only and contains both the PostgreSQL administrator
+password and the restricted `ocsentinel_n8n` password. Never commit it or copy
+it to endpoint devices.
+
+## n8n PostgreSQL Credential
+
+Create one credential in n8n with these non-secret values:
+
+| Setting | Value |
+| --- | --- |
+| Host | `ocsentinel-postgres` |
+| Port | `5432` |
+| Database | `ocsentinel` |
+| User | `ocsentinel_n8n` |
+| SSL | disabled (private Docker network) |
+
+Retrieve the password only on the server when entering the n8n credential:
+
+```bash
+sudo grep '^OCSENTINEL_N8N_PASSWORD=' /dockerstacks/ocsentinel-postgres/.env
+```
+
+The database schema source remains [../postgres/001_ocsentinel.sql](../postgres/001_ocsentinel.sql).

+# OfficeCom Sentinel PostgreSQL
+
+PostgreSQL is the private central store for endpoint reports. It is never
+contacted directly by an endpoint; only n8n uses a database account.
+
+## Provisioning
+
+The production instance is deployed as the private Dockge stack documented in
+[../dockge/README.md](../dockge/README.md). The bootstrap has already created
+the database, schema, and restricted `ocsentinel_n8n` role.
+
+For a separate future installation:
+
+1. Create a database named `ocsentinel` on the private PostgreSQL server.
+2. Apply `001_ocsentinel.sql` as a database administrator.
+3. Create a non-superuser n8n login and grant only the necessary permissions:
+
+```sql
+GRANT USAGE ON SCHEMA ocsentinel TO ocsentinel_n8n;
+GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA ocsentinel TO ocsentinel_n8n;
+GRANT USAGE, SELECT ON ALL SEQUENCES IN SCHEMA ocsentinel TO ocsentinel_n8n;
+GRANT SELECT ON ocsentinel.current_device_status, ocsentinel.organization_summary TO ocsentinel_n8n;
+ALTER DEFAULT PRIVILEGES IN SCHEMA ocsentinel
+  GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO ocsentinel_n8n;
+```
+
+Keep the database host, password, and TLS settings only in n8n credentials.
+They do not belong in Gitea, NinjaOne scripts, or endpoint configuration.
+
+## Maintenance
+
+Run monthly from n8n or an administrator session to remove expired replay tokens:
+
+```sql
+DELETE FROM ocsentinel.ingest_nonce WHERE expires_at < now();
+```
