Native per-endpoint identity instead of the schtasks bridge:
- Service (default) keeps the existing path - hooks inherit the service
account (SYSTEM by default, or whatever you installed under).
- SpecificUser binds ProcessStartInfo.UserName / Password / Domain so
the hook runs in a batch logon session as the named account. Useful
for AD-write hooks that should NOT run as SYSTEM.
- InteractiveUser uses WTSQueryUserToken(WTSGetActiveConsoleSessionId)
+ DuplicateTokenEx + CreateProcessAsUser to drop the child into the
logged-in user's session with their environment block. This is the
real fix for "calc.exe should pop up on my desktop" - no Task
Scheduler bridge required. Stdio is captured via inheritable
anonymous pipes so the hook still returns stdout/stderr to the
caller normally.
Implementation:
- New RunAsMode enum + RunAsConfig model on EndpointConfig
- ConfigStore round-trips RunAs.Password through DPAPI alongside
bearer/HMAC/PFX secrets
- AdminPipeServer's secret-merge logic preserves the encrypted blob
when the GUI saves an endpoint without re-typing the password
- New WebhookServer.Core.Execution.Native namespace with NativeMethods
(P/Invoke) and InteractiveProcessLauncher (token-based launcher)
- ProcessExecutor branches on RunAs.Mode; the Service/SpecificUser
paths share .NET's Process; InteractiveUser uses the launcher
- GUI editor gets a "Run as" section: dropdown + conditional
username/password/load-profile fields under SpecificUser
