Use mode=wrong_scaling and complete model={"values":[1,2],"probabilities":[[2,5],[3,5]],"process_certificate":"infinite_iid","n":5}. Give (mode, mean, variance, n, proposed_denominator, required_denominator, proposed_scaling_claim).
G001 — Use mode=wrong_scaling and complete model={"values":[1,2],"probabilities":[[2,5],[3,5]],"process_certificate":"infinite_iid","n":5}. Give (mode, mean, variance, n, proposed_denominator, required_denominator, proposed_scaling_claim).Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Before
source roles = [clt-application-boundary]
After
derived = [[mode, mean, variance, n, proposed_denominator, required_denominator, proposed_scaling_claim]]
Conditions: none
List the complete source field order and mode-specific roles without JavaScript or answer-shape inference;No,undefined and infinity retain their distinct meanings.

derived = [ASSUME infinite sequence is IID with this common marginal]
Conditions: none
infinite_iid is an explicit infinite-process premise token,not a construction or finite verification of infinite independence.Subsequent reasoning is conditional on that premise.

Before
source roles = [CLT ORIGINAL conditional marginal, [[1, 2/5], [2, 3/5]]]
After
derived = [8/5, 14/5, 6/25]
Conditions: none
Use the SAME complete law for E[X],E[X²] and Var(X)=E[X²]-E[X]².Keep value² as an exact teaching intermediate and apply the source profile to its product with probability,not an extra rejection for a large zero-mass value square.Finite moments prove neither independence,an infinite process nor a distributional limit.
Rule: CLT_ALL_finite_marginal_moments_not_a_process_or_limit_proof · Uses: G001, S017
Before
source roles = [wrong_scaling, 8/5, 6/25, 5]
After
derived = [wrong_scaling, 8/5, 6/25, 5, denominator=n*sigma, required=sigma*sqrt(n), No]
Conditions: none
The denominator must be sigma*sqrt(n),since Var(S_n)=n*sigma².The general formula n*sigma differs,but coincides at n=1;No does not assert numerical inequality in every instance.One finite histogram,even if normal-looking,does not prove a distributional limit.
