// ErrNotImplemented is returned by every UnimplementedCoreAPI method. It is
// deliberately distinct from ErrUnknownMethod (a wire-level "no such
// method exists" verdict) and from any daemon-level "locked" error: this one
// means "this method exists on CoreAPI, but the fake/adapter embedding
// UnimplementedCoreAPI never got a real implementation for it." A test that
// exercises an undeclared method fails loudly on this text instead of
// silently nil-panicking or being mistaken for a legitimate failure.
var ErrNotImplemented = errors.New("ipc: not implemented (unimplemented CoreAPI stub)")

// UnimplementedCoreAPI is the gRPC Unimplemented*Server pattern applied to
// CoreAPI: embed it in a test double or adapter and override only the
// methods you actually exercise. Every method returns ErrNotImplemented, so
// a call that reaches an undeclared method fails loudly and specifically,
// rather than compiling to a silent no-op or nil-pointer panic. This
// replaces the old pattern of hand-writing all 30 no-op stubs per double —
// those were compiler-satisfying padding, not tests of anything.
