The cli package's TestMain (internal/surface/cli/main_test.go) re-enters the abcd binary whenever ABCD_CLI_TEST_AS_BINARY=1 is in the environment, whatever the arguments, so an ambient marker makes go test of the package run zero tests, print the bare status board and pass. Test-only; the shipped binary carries no such symbol.

Grounds

• pursued: a compiled cli test binary run with the marker and -test.run runs the named test; one that prints the status board and exits 0 would show it wrong
