Use complete unique vertices=[v0, v1, v2] and loop-free duplicate-free undirected edges=[[v0, v1], [v1, v2], [v2, v0]]. An edge needs at least one selected endpoint. Preserve source canonical subset order. Mode=multiple_minima. Give (mode, edges, minimum_size, minimum_covers, mode_certificate, boundary).
G001 — Use complete unique vertices=[v0, v1, v2] and loop-free duplicate-free undirected edges=[[v0, v1], [v1, v2], [v2, v0]]. An edge needs at least one selected endpoint. Preserve source canonical subset order. Mode=multiple_minima. Give (mode, edges, minimum_size, minimum_covers, mode_certificate, boundary).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 = [mincover-empty-multiple-boundary]
After
derived = [[mode, edges, minimum_size, minimum_covers, mode_certificate, boundary]]
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 = [[v0, v1, v2], [[v0, v1], [v1, v2], [v2, v0]], null]
After
derived = [[v0, v1, v2], [[v0, v1], [v0, v2], [v1, v2]], null]
Conditions: none
The carrier is nonempty with at most12 vertices;sort endpoints by UTF16 then edge families in English.Reject loops/reversed duplicates.An omitted candidate stays null,not an invented empty candidate.
Rule: Mincover_complete_simple_graph_UTF16_English_and_optional_candidate · Uses: G001, S001
Before
source roles = [[v0, v1, v2], [[v0, v1], [v0, v2], [v1, v2]], 8]
After
derived = [[3, 5, 6, 7], [[0, 0], [1, 2], [2, 1], [4, 0]], [[v0, v1], [v0, v2], [v1, v2], [v0, v1, v2]], [0, 0, 3, 1], 2, [[v0, v1], [v0, v2], [v1, v2]]]
Conditions: none
Audit every mask against every edge,retaining the first uncovered-edge refutation for each failure and every accepted set in source order.Zero smaller-size counts give a lower bound and actual minimum covers attain it.Keep all ties in numeric-mask order,not English/size order.
Rule: Mincover_ALL_masks_acceptance_refutations_ALLcovers_ALLminimizers · Uses: G001, S002
Before
source roles = [multiple_minima, [v0, v1, v2], [[v0, v1], [v0, v2], [v1, v2]]]
After
derived = [2, [[v0, v1], [v0, v2], [v1, v2]], Yes]
Conditions: none
empty_graph means edgeless,not an empty vertex carrier;the unique minimum is empty.multiple_minima retains all of at least two solutions,not one witness as uniqueness.No Konig,weighted or directed extension.

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