Before
source roles = [qf-probability-weighted-event, weighted_event]
After
derived = [[reduced_probability_fraction_retaining_integer_denominator1]]
Conditions: none
List this scalar/label/set/point answer role or mode-specific ordered fields,not an imposed universal tuple.Retain legacy domain/underscore operation and integer fractions with/1;original bilingual snapshots stay unchanged.

S002 · implies
Before
source roles = [[8, 9, 10], powerset(S)]
After
derived = [[8, 9, 10], 3]
Conditions: none
S is a nonempty set of at most100 distinct SAFE integers and F is explicitly the FULL powerset,not an event family inferred from one event.

Before
Legacy probability ORIGINAL ALL numerator weights sum := sum(21, 1, 2)
After
Legacy probability ORIGINAL ALL numerator weights sum = 24
Conditions: none
Substitute original roles exactly,without floating approximation or changed operands;extra teaching identities add no source-domain restrictions.

Before
source roles = [[8, 9, 10], [21, 1, 2], 24]
After
derived = [[[8, 21], [9, 1], [10, 2]], 24, Yes, Yes, Yes, Yes]
Conditions: none
Bind weights to ORIGINAL raw S slots;set sorting does not change these associations.Validity needs a positive denominator,all nonnegative weights and the BigInt total equal to the denominator.A model-validity question may legally answerNo,without0/0,sign repair or renormalizing another model.

After
derived = [0, [8, 9, 10], 0, 0/1]
Conditions: none
On the full powerset define every event by its ORIGINAL weighted sum.Nonnegativity,total1 and regrouping disjoint events give finite(and countable,for finite S)additivity.A nonempty E can have mass0.The complement is in the SAME S;do not substitute sorted-slot weights or uniform counts.
