صِحَّةُ التَّعْيِينِ وَقُوَّةُ الدَّلِيلِ
Correct classification and strong evidence.
Check four items for each problem: (1) contextual meaning, (2) the defining formal or semantic condition, (3) the reason a close alternative fails, and (4) the expressive benefit.
Do not convert uncertain literary attribution into asserted historical fact. Maintain distinctions among scriptural incorporation, poetic inclusion, and commonly shared subject matter.
