APPLICATION PROFILES DESIGNED

DailyTech & Tuning (39 apps)

  • Purpose: ECU tuning, reverse engineering, binary analysis
  • Core Apps: 22 (Git, Python, VS Code, WinHex, ImHex, Ghidra, Sysinternals, etc.)
  • Optional: 17 (VirtualBox, SavvyCAN, Binwalk, CyberChef, etc.)
  • Focus: Hex editing, binary disassembly, CAN analysis, firmware modification

ODIS & XENTRY (25 apps)

  • Purpose: VAG/Mercedes OEM diagnostics
  • Core Apps: 21 (shared tools + diagnostics-specific)
  • Optional: 4 (media, compression, search)
  • Focus: VIN-based coding, fault diagnosis, module software

  • Core Apps: 21 (shared tools + diagnostics-specific)
  • Optional: 4
  • Focus: PIWIS sessions, PSdZData, LoJack module access

EXECUTION MODES

Audit Mode          → Scan current state (no setup changes)
Plan Mode           → Generate Windows and application plans
Apply Mode          → Full installation with checkpoint persistence
Repair Mode         → Accepted mode; currently follows idempotent apply behavior
HealthCheck Mode    → Verify workstation health
Backup Mode         → Save current configuration
Restore Mode        → Restore the latest configuration backup
Inventory Mode      → Inventory support through the audit/reporting path
UpdatePortable Mode → Run portable-app flow without WinGet
CreateWorkspace     → Initialize a profile-specific project

CHECKPOINT & RESTART RECOVERY

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 and revalidate prior work
  6. Continue safely → Idempotent installers continue from the saved execution context

DOWNLOAD SECURITY

The implementation currently validates downloads through:

  1. HTTPS Enforcement — Encrypted, prevents man-in-the-middle
  2. File Size Check — Detects truncation or injection
  3. Archive Integrity — Tests ZIP/7z before extraction
  4. Expected Files — Verifies correct files extracted
  5. SHA256 Hash — Cryptographic integrity verification
  6. Authenticode — Digital signature on executables
  7. Malware Scan — Reserved for the planned security expansion

HTTP allowed only on documented allow-list with strong justification.

NEXT STEPS

Remaining implementation

  • Split the monolithic script into the planned PowerShell modules
  • Complete dedicated Repair and Inventory mode dispatch
  • Add automatic restart prompting and phase skipping
  • Populate and enforce trusted SHA256 values for portable releases
  • Add Windows Defender malware scanning integration
  • Expand the Pester suite toward the PHASE-8 target
  • Run elevated Apply tests on clean profile workstations
  • Complete deployment packaging and production rollout

RECOMMENDATION FOR NEXT PHASE

Ready for the remaining hardening and deployment work?

The design is complete and the first five implementation weeks are validated. The remaining work is focused on hardening and production rollout:

  1. Complete remaining mode semantics — Repair, Inventory, and automatic resume skipping
  2. Harden download trust — Populate trusted hashes and add malware scanning
  3. Split modules — Extract configuration, download, Windows, workspace, and reporting modules
  4. Run elevated Apply tests — Validate WinGet, portable downloads, drivers, and restart behavior
  5. Package and deploy — Test on clean workstations before production rollout

All 9 phase documents are ready to guide development. The specifications are detailed enough for a developer to implement without extensive back-and-forth.
