Original question and givens

Use mode=single_split, complete model={"p":5,"word":["a","a","a","a","a","b"],"x_length":4,"y_length":1}. Give (mode, p, word, x_length, y_length, z_length, split_legal, pumping_quantifiers_resolved_claim, boundary).

  • G001 — Use mode=single_split, complete model={"p":5,"word":["a","a","a","a","a","b"],"x_length":4,"y_length":1}. Give (mode, p, word, x_length, y_length, z_length, split_legal, pumping_quantifiers_resolved_claim, boundary).

Definition and scope

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.

Step-by-step derivation

S001 · implies

Before

source roles = [pump-boundary]

After

derived = [[mode, p, word, x_length, y_length, z_length, split_legal, pumping_quantifiers_resolved_claim, boundary]]

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.

Step identifiers and dependencies

Rule: source_ordered_fields_without_JS · Uses: G001

S002 · implies

Before

source roles = [5, [a, a, a, a, a, b], 4, 1]

After

derived = [1, Yes, No]

Conditions: none

This split is actually legal,but one decomposition does not resolve the exists-split/forall-i language obligation or establish regularity.No does not deny legality.

Step identifiers and dependencies

Rule: Pumping_one_ACTUALLY_legal_split_NOT_quantifiers_resolved · Uses: G001, S001

Reverse checks

  • S002 · premise_and_result_audit — Reverse-check the complete original data,step operands and premises;finite checks,conditional named-theorem use and general formal proof remain distinct.
  • S001 · premise_and_result_audit — Reverse-check the complete original data,step operands and premises;finite checks,conditional named-theorem use and general formal proof remain distinct.

Result

(single_split, 5, [a, a, a, a, a, b], 4, 1, 1, Yes, No, one_decomposition_does_not_resolve_exists_split_forall_i)

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
