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.
synthetic proposition/term calculus or supplied synthetic receipt
After
no actual Lean build,source-digest check or kernel acceptance
Conditions: none
Apply only the specified small calculus or synthetic receipt protocol.Statement,tactic completion,term presence and kernel acceptance are separate.No Lean is run and the teaching guide is not promoted to a formal proof.
IDs and shapes qualified=No;supplied kernel flag=Yes;axioms recorded=Yes
After
synthetic qualified=No;status=composition receipt still incomplete
Conditions: none
Qualification additionally requires the supplied kernel flag;field completeness also requires the axioms-recorded flag.Both merely classify synthetic data,not real kernel acceptance or a semantic trust certificate.
S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
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
(missing, thm-18, Yes, No, Yes, Yes, No, synthetic-receipt-still-incomplete)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
