R0051-26222 · q-20261015-advance-20261116-r01-contraction-mapping-theorem-0097

Original question and givens

Use boundary mode=non_self_map and positive exact scale=22. Give (mode, scale, mapping_description, theorem_application_claim).

  • G001 — Use boundary mode=non_self_map and positive exact scale=22. Give (mode, scale, mapping_description, theorem_application_claim).

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 = [contract-boundary]

After

derived = [[mode, scale, mapping_description, theorem_application_claim]]

Conditions: none

List the full source field order without JavaScript.Original modes select contract6/4/6/6 and IVT8/7/8 roles,without padding or answer-shape inference.

Step identifiers and dependencies

Rule: source_ordered_fields_without_JS · Uses: G001

S002 · implies

Before

source roles = [non_self_map, 22]

After

derived = [non_self_map, 22, T_maps_one_point_outside_X, No]

Conditions: none

The two-point identity at q1 has two fixed points;nonself maps do not iterate in the same space;on(0,s),(x+s)/2 has its fixed point s outside.sampled_pairs supplies only source scope,not a complete recomputable metric/map counterexample.

Step identifiers and dependencies

Rule: Contraction_original_boundary_mode_actual_scope_not_invented_witness · Uses: G001, S001

Reverse checks

  • 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.

Result

(non_self_map, 22, T_maps_one_point_outside_X, No)

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