Co-locate the two cockpit-pod projects into a single repository:
- Console/ : TeslaConsole, the net48 WinForms operator console (decompiled
reconstruction) plus its differential + catalog test suite.
- Launcher/ : TeslaLauncher, the net6 pod-side Service + Agent rewrite.
Adds a combined TeslaSuite.sln, root README documenting the shared wire
contract (and its current duplication, the main follow-up), and a root
.gitignore. Histories were not preserved per request; this is a fresh start
from the current working state of both projects.

TeslaConsole.DiffTests — differential equivalence suite
Verifies that the reconstructed TeslaConsole.exe (built from the decompiled
source in this repo) behaves identically to the original reference binary in
original/TeslaConsole.exe.
How it works
Both files carry the exact same assembly identity
(TeslaConsole, Version=4.11.3.37076), so the .NET loader will not hold both in
one AppDomain. The suite therefore loads each assembly into its own child
AppDomain (DifferentialFixture) and drives it through a MarshalByRefObject
proxy (Invoker). This is why the project targets net48 — AppDomains are a
.NET Framework feature.
Each child domain is given a probe directory (the recovered build's output, which ships every dependency DLL) so the original — which is distributed without its proprietary dependencies — still resolves its references for metadata inspection.
What is compared
-
Public API surface (
PublicApiSurfaceTests) Every public type and public member (signature-for-signature) exposed by the original must also be exposed by the recovered build. Compiler-generated members and property/event accessor methods are excluded — the README at the repo root notes those legitimately differ between a decompilation and the lost sources. -
Behavioral output (
BehavioralEquivalenceTests) The same deterministic, dependency-free methods are invoked in both assemblies over a battery of inputs and the results must match byte-for-byte:RPStrings.GetTimeString(mm:ss formatting + 0.5 s rounding)HostTypeHelper.Parse(...).ToString()(incl. invalid-input exceptions)PlasmaBitmaps.ConvertBitmap(1-bpp packing of a known pixel pattern)PlasmaBitmaps.GenerateString(full GDI text → 1-bpp plasma pipeline)RPMap/RPVehicleXML parsingSiteManagementwell-known application GUID constantsTuple.Create<,>generic factory
A negative-control test (
Harness_Distinguishes_Different_Outputs) proves the harness can actually see a difference, so a green run is never vacuous.
Running
dotnet test tests/TeslaConsole.DiffTests/TeslaConsole.DiffTests.csproj
A project reference builds the reconstruction first, and the suite always tests
the most recently built bin/{Debug,Release}/net48/TeslaConsole.exe.
Scope / limitations
This compares deterministic logic. It deliberately does not drive the WinForms UI, the pod networking, secure-configuration, or hardware-facing code — those require the live console, its pods, and the proprietary services, and are not reproducible in a unit test. The API-surface test still asserts those types exist with matching signatures even though their behavior isn't exercised.
