Summary & Methodology Clarification — The Photogravitational Model

Summary & methodology clarification for the photogravitational model. States that φ = L/(M a) is in [m/s], that current G = a R² / M results are consistency checks, and specifies the conditions for a non-circular single-star estimate of G. No formulas or numbers are changed; the Sun closes at ~0.1% vs CODATA.本文件针对光引力模型（photogravitational model）开展总结与方法学澄清，明确φ = L/(M a) 的单位为米每秒（m/s）；指出当前基于G = a R²/M 推导得到的结果可用于一致性检验；并规定了引力常数G的非圆轨道单星估算所需的条件。本次内容未改动任何公式与数值；相关太阳模型的计算结果与国际科学技术数据委员会（CODATA）标准值的偏差约为0.1%。
