Use scalar theta=10, complete estimator values=[10, 12, 14] and aligned exact probabilities=[1/4, 1/2, 1/4]. Under this same P_theta the nonnegative probabilities sum to1. Retain zero-mass listed rows and sort values with their own probabilities. Give (theta, law_rows, mean, bias, variance, MSE, variance_plus_bias_squared, identity_holds, certificate).

Compute mean, bias, variance and MSE separately under the same law, then compare the direct MSE with variance+bias^2. The identity is a finite scalar-law certificate, not consistency or an asymptotic claim.

Compute the observed squared error separately from expected loss. If unbiased, verify MSE=variance; otherwise verify MSE≥variance. The last No withholds consistency, not possible coincidence between one observed loss and MSE. Unbiasedness may coexist with positive variance and MSE. The exact result, retaining the requested order, is (3, 3, 0, 1, No, 1/2, 3/2, Yes, No, No, unbiased_only_gives_MSE_equals_variance_not_zero_MSE_or_consistency_and_observed_error_is_not_MSE).

Use scalar theta=4, complete estimator values=[2, 4, 6] and aligned exact probabilities=[1/4, 1/2, 1/4]. Under this same P_theta the nonnegative probabilities sum to1. Retain zero-mass listed rows and sort values with their own probabilities. Given listed observed estimate=2. Give (theta, observed, observed_squared_error, bias, unbiased, variance, MSE, variance_comparison_holds, unbiased_and_zero_MSE, consistency_claim, boundary).

variance_comparison_holds checks MSE=variance when unbiased, otherwise MSE≥variance. One observed loss may coincide with MSE; the final No does not deny coincidence or establish consistency.
