Use boundary mode=q_equal_one and positive exact scale=5. Give (mode, scale, metric_description, q, fixed_point_counterexample, theorem_application_claim).
G001 — Use boundary mode=q_equal_one and positive exact scale=5. Give (mode, scale, metric_description, q, fixed_point_counterexample, theorem_application_claim).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 = [contract-boundary]
After
derived = [[mode, scale, metric_description, q, fixed_point_counterexample, 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.
Rule: source_ordered_fields_without_JS · Uses: G001
Before
source roles = [q_equal_one, 5]
After
derived = [q_equal_one, 5, two_point_metric, 1, identity_map_has_two_fixed_points, 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.

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.(q_equal_one, 5, two_point_metric, 1, identity_map_has_two_fixed_points, No)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.

Original questions, answers, step expressions, numeric ASTs and historical records are retained. Source candidate labels remain historical and are not overwritten as formal proof.
