Original question and givens
Use complete epsilon-NFA states=[s5, m5, f5, e15, e25, d5], alphabet=[a5, b5], start=s5, final_states=[f5], transitions=[[s5, null, m5], [s5, null, d5], [m5, a5, m5], [m5, b5, f5], [f5, null, e15], [e15, null, e25]]. Each transition is [from,input symbol or null,to], with null consuming no input. States/labels and transitions must qualify, and subsets are unique carrier subsets sorted lexicographically. Empty alphabet/final sets and empty subset states are allowed. Given subset S=[s5, m5, d5], input symbol=b5. Give (subset, symbol, symbol_targets, epsilon_closed_targets, empty_dead_state, certificate).

Step-by-step derivation
S001 · implies
Before
source operation=subsetdfa-symbol-transition;original snapshot and mathematics retained
After
explicit ordered source output fields=[subset, symbol, symbol_targets, epsilon_closed_targets, empty_dead_state, certificate]
Conditions: none
Keep the source snapshot while listing ordered fields without JavaScript.Radius uses its original mode to select6 or11 fields without padding;distinguish nonclaims from actual negations.

S002 · implies
Before
ORIGINAL states=[s5, m5, f5, e15, e25, d5],alphabet=[a5, b5],start=s5;ORIGINAL transition order=[[s5, null, m5], [s5, null, d5], [m5, a5, m5], [m5, b5, f5], [f5, null, e15], [e15, null, e25]]
After
final set normalized UTF16=[f5];states nonempty,alphabet/finals/relation MAYEMPTY;DUPLICATE triples rejected in THIS model
Conditions: none
This model differs from the earlier NFA node:transition triples are unique and finals are sorted.Subsets must be actual carrier subsets;do not import old duplicate/final-order conventions.

S003 · implies
Before
Subset DFA ORIGINAL one-symbol transition:EXACT ORIGINAL supplied S=[d5, m5, s5];symbol=b5;ALL matching ORIGINAL edge rows=[[3, m5, f5]]
After
direct symbol targets=[f5];NO EPS preclosure inserted into S;now close ONLY these targets
Conditions: none
An arbitrary supplied S need not be EPS-closed;preclosing it would change this operation.Apply move(S,a) and then close its targets.Empty targets yield the legal empty dead state.
