+## Repair Missing NinjaOne Context
+
+NinjaOne exposes `NINJA_ORGANIZATION_ID`, `NINJA_ORGANIZATION_NAME`,
+`NINJA_AGENT_MACHINE_ID`, and location values only while an automation runs.
+The scheduled OCSentinel task runs later as `SYSTEM`, so those values must be
+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`. Do not run this
+script from an interactive PowerShell session, because NinjaOne does not expose
+the required environment values there.
