An instruction is an authoritative direction to be obeyed. What part of
"November 1234, radar contact..." do you consider to be an instruction?

My bad. Your postulate was invalid. "November 1234, radar contact."
is not an instruction. It does, however, "establish two-way radio
communication" which authorizes entry into Class C airspace.
Entry into Class C airspace does not require affirmative instructions,
unlike Class B airspace which requires an affirmative clearance.
If ATC wants you to remain clear, they have to keep saying so if they
are going to communicate using your tail number.

Michael
