Truth that exists within a closed system—a framework with fixed premises, fixed rules, and no outside influence. In a closed system, truth is stable, certain, and final—as long as you accept the system's axioms. This is the truth of mathematics (within a given axiomatic system), of dogma (within a given faith), of ideology (within a given framework). Closed system truth is comforting because it never changes, but it's limited because it can't learn. It's the truth of people who have all the answers and never need new questions.
Example: "He lived in closed system truth: his religion, his politics, his worldview—all sealed, all certain, all final. When confronted with evidence that challenged his system, he didn't update; he defended. The system was closed, and nothing new could enter. He was certain, peaceful, and completely unable to learn. Closed system truth had given him certainty at the cost of growth."
