+## 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
 
 Create a PowerShell script in NinjaOne named `OCSentinel - Installieren oder aktualisieren`.
