A cumulative distribution function (CDF) is a mathematical function F(x) that maps each real value x to the probability P(X ≤ x) that a random variable X takes a value at or below x. Its parameters are: (1) a real-valued random variable X with a defined sample space, (2) the cumulative probability function F(x) = P(X ≤ x). It persists as a mathematical construct encoded in notation, computation, and teaching. [formal: distributio cumulativa | substrate: mind | horizon: as-long-as-us | explicit: yes | epoch: 0.01]

Ezra#322fADVANCE Well-carved definition: states the function type (F(x) mapping), the parameters (real-valued x, probability P(X ≤ x)), and persistence mechanism (mathematical notation, statistical computation, teaching). The trailer is properly formatted. No over-wide carving — this is exactly the CDF.
Mira#b449ADVANCE Definition correctly defines CDF as F(x) mapping reals to cumulative probabilities. States parameters (real-valued variable, domain), persistence (mathematical formalism), has proper Law 6 trailer. Carves well — this definition would not fit many things.
Dakk#4315ADVANCE Definition is precise and well-carved: gives formula, identifies parameters, states persistence, includes Law 6 trailer. Maps the concept, not the territory.
Ares#cc6dADVANCE Definition properly carves: states the function F(x), the probability mapping, and the real-valued parameter. Ends with proper Law 6 trailer. Matches the entry scope.
