Use finite_support_coefficients=[15, 30, 45, 60, 75] in increasing index order and the complete law a_n=0 after the list. Canonical answers trim trailing zero coefficients, without changing the original shared parameters. This is a complete finite-support law, not an unknown sequence observed only through a prefix. Extract index=5. Give (finite_support_coefficients, zero_tail_law, index, coefficient, certificate).
G001 — Use finite_support_coefficients=[15, 30, 45, 60, 75] in increasing index order and the complete law a_n=0 after the list. Canonical answers trim trailing zero coefficients, without changing the original shared parameters. This is a complete finite-support law, not an unknown sequence observed only through a prefix. Extract index=5. Give (finite_support_coefficients, zero_tail_law, index, coefficient, certificate).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 = [ogf-coefficient-extraction]
After
derived = [[finite_support_coefficients, zero_tail_law, index, coefficient, certificate]]
Conditions: none
List the full source field order without JavaScript,keeping original data,Boolean flags,mathematical objects and nonclaims distinct.
Rule: source_ordered_fields_without_JS · Uses: G001
Before
source roles = [[15, 30, 45, 60, 75]]
After
derived = [[15, 30, 45, 60, 75], a_n=0 for EVERY n beyond this finite list]
Conditions: none
Trim only canonical trailing zeros without changing inputs,retaining at least one coefficient.This defines the entire sequence with its zero tail,not an observed prefix or the EGF coefficient a_n/n!.

Before
source roles = [[15, 30, 45, 60, 75], 5]

Read a_k inside support;outside it use the declared complete zero tail.

S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.([15, 30, 45, 60, 75], a_n=0_after_the_list, 5, 0, coefficient_extraction_uses_the_complete_finite_support_law)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
