Three test seams were still package-level mutable vars, which tests
had to swap before use. That's the classic path to flaky parallel
tests — two goroutines fighting over the same global fake. Push each
down to the struct that owns the behaviour.
internal/daemon/dns_routing.go
lookupExecutableFunc + vmDNSAddrFunc → fields on *HostNetwork,
defaulted at newHostNetwork time. dns_routing_test builds
HostNetwork{..., lookupExecutable: stub, vmDNSAddr: stub} inline,
no more t.Cleanup dance around package-level vars.
internal/daemon/preflight.go + doctor.go
vsockHostDevicePath (mutable string) → vsockHostDevice field on
*VMService, defaulted via defaultVsockHostDevice constant in
newVMService. Preflight reads s.vsockHostDevice; doctor reads
d.vm.vsockHostDevice. Logger test sets d.vm.vsockHostDevice = tmp
after wireServices.
internal/daemon/workspace/workspace.go
HostCommandOutputFunc → *Inspector struct with a Runner field.
Every git-using helper (GitOutput, GitTrimmedOutput,
GitResolvedConfigValue, RunHostCommand, ListSubmodules,
ListOverlayPaths, CountUntrackedPaths, InspectRepo,
ImportRepoToGuest, PrepareRepoCopy) is now a method on *Inspector.
NewInspector() wraps the real host runner for production;
WorkspaceService holds one via repoInspector, CLI deps holds one
too. cli_test.go's submodule-rejection test builds its own
Inspector with a scripted Runner instead of patching a global.
Pure helpers (FinalizeScript, ResolveSourcePath, ParsePrepareMode,
ShellQuote, FormatStepError, GitFileURL, ParseNullSeparatedOutput)
stay free functions since they don't touch the host.
Sentinel: grep for HostCommandOutputFunc, lookupExecutableFunc,
vmDNSAddrFunc, vsockHostDevicePath is now empty across internal/.
make lint test green.
