Fleet maintenance tool for Jam Coding classroom laptops. One self-elevating EXE that pulls its config from this repo and runs cleanup, app installs, folder sync, wallpaper enforcement, and arbitrary admin commands.

1. Tech runs Jaminator.exe --install once per laptop. UAC prompts. Jaminator copies itself to C:\Program Files\Jaminator\ and registers a scheduled task that auto-runs at every user logon.
2. At logon (auto, headless) Jaminator runs only the login-safe sections:
   • folders — ensure school folders exist under Documents/
   • wallpaper — refresh canonical wallpaper, revert any kid-change
3. On demand (UI, by tech) the tech opens Jaminator from the Start Menu to run anything disruptive — cleanup, app installs, registry tweaks. None of these run at logon, so a class in progress is never interrupted.
4. The whole control plane lives in manifest/manifest.json in this repo. Edit + commit and every laptop picks up the change next launch.
5. Every action is logged to screen and to C:\ProgramData\Jaminator\logs\.

manifest/manifest.json    # live config (folders, apps, commands, wallpaper)
assets/                    # wallpaper.png and other static assets
src/Jaminator/             # C#/.NET Framework 4.8 WinForms project
docs/                      # schema docs

You don't redeploy the EXE for config changes — just edit manifest/manifest.json and commit. Every laptop picks up the change next time it runs.

For a new version of the tool itself: tag a release in GitHub with the EXE attached. Jaminator self-updates on next launch if a newer tag exists.

See docs/manifest-schema.md.

Requires .NET SDK 8+ (only for the build — produces a .NET Framework 4.8 EXE that runs on any Win10/11, 32 or 64-bit, with no runtime install).

dotnet build src/Jaminator -c Release

Output: src/Jaminator/bin/Release/net48/Jaminator.exe

• Public repo. Anyone can read; only repo collaborators can push.
• Every download (MSI, wallpaper) is verified against a sha256 in the manifest. Tampered downloads are refused.
• Tool executes arbitrary PowerShell from the manifest, so the manifest itself is the trust root. Treat write access to this repo as admin access to every Jam Coding laptop.
