Original question and givens

Declared evidence_mode=failed_candidate_encoding, certificate_parameter=3. The registered modes complete_finite_list and universal_affine_injection refer to their supplied complete or universal certificates; failed_candidate_encoding records only a failed witness. Give (evidence_mode,certificate_parameter,proved?,classification).

  • G001 — Declared evidence_mode=failed_candidate_encoding, certificate_parameter=3. The registered modes complete_finite_list and universal_affine_injection refer to their supplied complete or universal certificates; failed_candidate_encoding records only a failed witness. Give (evidence_mode,certificate_parameter,proved?,classification).

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

registered DECLARED evidence mode=failed_candidate_encoding;numeric certificate parameter=3

After

qualifying declared certificate flag=No;classification=no_classification_from_failed_witness

Conditions: none

This audits the declared complete or universal certificate mode;the numeric parameter does not construct or verify an unspecified set.A failed encoding refutes that witness,not countability itself.At most countable does not mean countably infinite.

Step identifiers and dependencies

Rule: countability_declared_evidence_mode_not_unspecified_set_construction · Uses: G001

Reverse checks

  • S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

(failed_candidate_encoding, 3, No, no_classification_from_failed_witness)

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