 ## CHECKPOINT & RESTART RECOVERY
 
-The new system can **resume after a forced restart** (WinGet often requires reboot):
+The current system persists execution checkpoints and can be explicitly resumed after a restart:
 
 1. **Execution starts** → Create checkpoint with ExecutionId
 2. **Phase completes** → Update checkpoint, log progress
 3. **Restart detected** → Save state to disk, prompt user
 4. **System reboots** → Checkpoint persisted, waiting for resume
-5. **Script resumes** → Load checkpoint, skip completed phases
-6. **Continue from where it left off** → Full transparency and recovery
+5. **Script resumes** → Load checkpoint and revalidate prior work
+6. **Continue safely** → Idempotent installers continue from the saved execution context

+# Troubleshooting
+
+## Pester is not installed
+
+Install Pester for the current user, then rerun the test runner:
+
+```powershell
+Install-Module Pester -Scope CurrentUser -Force
+.\Tests\\Run-AllTests.ps1
+```
+
+## Script reports that administrator privileges are required
+
+`Apply`, `Repair`, `Restore`, `UpdatePortable`, and Windows configuration changes require an elevated Windows PowerShell window. Use `Plan`, `Audit`, `HealthCheck`, or `CreateWorkspace` when elevation is not available.
+
+## A shared drive is unavailable
+
+The setup expects `S:` for shared automotive data and `P:` for shared portable applications. `HealthCheck` reports their availability and labels. Portable applications fall back to the local `C:\Automotive\PortableApps` path when `P:` is unavailable, but shared profile data remains unavailable until the drive is mounted.
+
+## A download is blocked as insecure
+
+Downloads must use HTTPS. HTTP is rejected unless the caller explicitly marks a documented vendor exception. The current exception is limited to the Xhorse assets whose vendor CDN does not provide HTTPS. Verify the vendor network/VPN path and confirm the URL before retrying.
+
+## A portable download fails hash or signature validation
+
+Do not bypass the failure. Preserve the downloaded file, compare its SHA256 value with the trusted vendor release information, and inspect the Authenticode status. Remove the file only after the incident has been recorded. Update `Config\\portable-apps.json` only with a verified expected hash.
+
+## Resume after restart
+
+Check `C:\Automotive\Config\\.workstation-setup-state.json` or the configured local root for the last checkpoint. Resume with the same profile and `-ResumeFromCheckpoint`. Completed work is revalidated because installers and vendor packages can change between runs.
+
+## Workspace creation fails
+
+`CreateWorkspace` requires `-JobId`, `-Manufacturer`, and `-Model`. Job IDs, manufacturers, and models cannot contain path separators or Windows filename characters. Use a simple value such as `VW001`, `Volkswagen`, and `Golf`.
+
+## OEM or communication software installation
+
+The setup does not silently install licensed OEM suites. Use the vendor installer, complete licensing and device registration on the current Windows installation, and verify J2534/USB drivers separately. Keep other isolated Windows installations without drive letters while working in the current profile.

+## Reports and State
+
+Reports are written under the configured local root:
+
+- `Logs`: setup logs, CSV summaries, plans, and workspace results.
+- `Config`: local profile metadata, Windows state, and checkpoint state.
+- `Manifests`: portable application hashes and inventories when the shared portable root is available.
+
+The checkpoint file is `Config\\.workstation-setup-state.json`. Resume a prior apply run with:
+
+```powershell
+.\Automotive-Workstation-Setup.ps1 -Mode Apply `
+  -WorkstationProfile 'DailyTech & Tuning' -ResumeFromCheckpoint
+```
+
+## Workspace Data Handling
+
+Always preserve original ECU, EEPROM, and coding reads in the `Originals` or profile-equivalent folder. Calculate hashes before editing. Keep modified files in `WorkingCopies`, `CodingBackups`, or the matching profile folder. Do not flash or code a vehicle without authorization, verified backups, stable power, and a vendor-supported procedure.
+
+## Testing
+
+Run the Pester suite from the repository root:
+
+```powershell
+.\Tests\\Run-AllTests.ps1
+```
+
+The suite is designed to use temporary roots and does not install applications or modify Windows settings.
