Original question and givens

Use finite unique labeled points=[a14, b14, c14] and the complete canonical topology=[[a14, b14, c14], [a14, b14], [a14, c14], [a14], [c14], []]. Every neighborhood witness must be a declared open set containing its assigned point; the two points must be distinct and the witnesses disjoint. The complete topology must qualify before a Hausdorff audit. Supplied sampled_pairs=[[c14, a14]]. Give (sampled_pair_rows, all_sampled_separated, sample_count, total_pair_count, general_sample_certificate, boundary).

  • G001 — Use finite unique labeled points=[a14, b14, c14] and the complete canonical topology=[[a14, b14, c14], [a14, b14], [a14, c14], [a14], [c14], []]. Every neighborhood witness must be a declared open set containing its assigned point; the two points must be distinct and the witnesses disjoint.

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 operation=hausdorff-sampled-boundary;original snapshot and mathematics retained

After

explicit ordered source output fields=[sampled_pair_rows, all_sampled_separated, sample_count, total_pair_count, general_sample_certificate, boundary]

Conditions: none

Keep the historical interface marker and list ordered source fields without JavaScript.Tags are not additional evidence;fixed No markers retain their scope.The ordering helper supplies protocol order,not mathematical correctness.

Conditions: none

Samples may be empty,repeat pairs or actually cover every finite pair.Position count is not distinct-pair count.The fixed No negates neither true separation results nor a finite conclusion with separately established completeness;finite sampling does not certify an infinite space.
