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.
Retain the ORIGINAL bank full operation prefix,domain and ordered answer roles.Use orthogonal_equal_unit only where a frame is declared,and degrees where an angle unit is declared.Integer fractions retain/1.Do not invent parameters or alter original bilingual sources.
Substitute exact ORIGINAL roles,without floating approximation.SAFE bounds raw inputs only;derived integers/rationals are unbounded and do not inherit another bank component cap.

The flag tests total<=180,NOT total<=target.With target90,total100 may have flagYes and remainder-10.Each raw part is within0..180;an accumulated540 is legal arithmetic but not an angle in this entry.Keep original prefix order without sorting/wrapping.
S006 · premise_and_result_audit — Reverse-check this step against the ORIGINAL data,indices and premises,without claiming the conclusion uniquely recovers the inputs.Finite exact checking,independent review,formal proof and publication clearance remain separate.
S005 · premise_and_result_audit — Recompute Angle ORIGINAL target minus total with exact rational arithmetic, not rounded decimals.

Result
([11, 101, 113], Yes, -23)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
