Case. One parent is strict, the other lenient; they argue in front of the child, who learns to play on the gap.
Model. Two unaligned access policies in one system — the child finds privilege escalation through the adults’ contradiction.
Protocol. Align rules between adults in advance and in private; a united front before the child.
Lesson. Disagreements are resolved in the backend, not in production before the user.
