Merge TeslaLauncherService (Session 0) + TeslaLauncherAgent (tray) into one
userland TeslaLauncher.exe. The split existed only to work around Vista+
Session 0 isolation; running everything in the auto-logged-in admin session
needs no service, no named pipe, and no flat<->wire conversion layer. The
original Elsewhen software was likewise a single binary.
net40 is the newest framework XP SP3 can install, and net40 assemblies load
in-place on the 4.8 runtime in Win10/11 -- one exe covers both.
- Contract: multi-target net48;net40. The net40 leg of PodRpcProtocol uses
Newtonsoft.Json (STJ has no net40 target); JSON is shape-identical on the
wire, and the request reader keeps date strings raw so Ping echoes
byte-identically. Console keeps the untouched net48/STJ leg.
- MiniZip.cs: central-directory ZIP extractor (stored/deflate/ZIP64) since
net40 has no ZipFile; zip-slip guarded.
- SecureConfig: RSACryptoServiceProvider instead of RSA.Create (net46+),
no leaveOpen BinaryWriter/Reader, struct instead of ValueTuple, and no
SetCompatibleTextRenderingDefault on the passcode thread (the merged app
already has a form). netsh "interface ip" syntax was already XP-correct.
- Volume: nircmd -> CoreAudio (Vista+) -> winmm waveOutSetVolume (XP).
- Paths: CommonApplicationData resolved per-OS (XP has no C:\ProgramData);
launcher log moved next to the key/config in the data dir.
- install.bat: dual-OS (cacls/icacls, netsh firewall/advfirewall, dism and
UAC/notification steps skipped on XP, .NET 4.0 redist check, XP DHCP reset
via netsh); no service registration -- HKLM Run key + auto-login on both;
RegisterApplicationRestart supplies crash-restart on Vista+.
- Bench switches: /skipconfig, /port:NNNN.
Verified: Console + diff suite (103 tests) still green on the net48 leg;
E2E smoke test drove the net40 launcher over real TCP with the Console's own
PodManagerConnection (STJ client vs Newtonsoft server) -- Ping echo, volume,
app registry, launch/kill/watch, InstallProduct zip transfer + extract, and
uninstall orphan cleanup: 17/17 pass.

Make the Console<->Launcher system source-built and modern now that the console
is under our control and the WinXP-era pods are gone.
Contract extraction (Contract/Tesla.Contract.csproj):
- One multi-targeted (net48;net8.0-windows) source project for the RPC contract,
replacing the vendored TeslaConsoleLaunchLib.dll and the hand-synced Tesla.Net
replica in Launcher/LaunchModels_Shared.cs. Emits assembly TeslaConsoleLaunchLib.
SecureConfig extraction (SecureConfig/Tesla.SecureConfig.csproj):
- net48 source of the first-boot provisioning protocol (UDP beacons, OFB crypto,
RSA key exchange), replacing the vendored TeslaSecureConfiguration.dll.
Remove BinaryFormatter from the wire (RCE sink + the reason net6 was pinned):
- Console<->Launcher RPC is now length-prefixed System.Text.Json frames
(Contract/PodRpcProtocol.cs) over the unchanged OFB transport; dispatch by
method name. Deleted the SerializationBinder / MethodInfoProxy machinery.
- Console-local BinaryFormatter (Site config, mission replays) intentionally
retained: local net48 file I/O, not the network surface.
Runtime modernization:
- Launcher Service + Agent: net6 -> net8, win-x86 -> win-x64 (all pods are
64-bit Win10). Kept the SHA1-default PBKDF2 (Console key-derivation compat)
with SYSLIB0041 suppressed and documented.
Tests: differential suite now 73 green. Added SecureConfigCompatTests (OFB
ciphertext byte-identical to the vendored DLL) and PodRpcProtocolTests (JSON
round-trip of every request/response shape); removed the now-obsolete
BinaryFormatter byte-identity guard.
Build hygiene: per-project obj dirs (Launcher/Directory.Build.props) fix a
NuGet restore collision between the two Launcher projects sharing one folder.
NOT runtime-verified against a live pod.
