独立复现Godfrey-Isgur相对论化夸克模型，开源Julia包复现全部209个能级及各类衰变表，验证精度高，提供波函数与智能体接口。
AI中文摘要：
Godfrey和Isgur（1985年）提出的相对论化夸克模型，在发表四十年后仍是介子谱学的参考标准，然而尽管其影响深远，其背后的计算从未公开。我独立复现了整篇论文，并将其作为开源Julia包发布，网址为this http URL，同时附带用于跃迁观测量及与原始论文比较的配套包。使用已发表的参数而不重新拟合，论文的三阶段谐振子算法用独立的有限差分求解器进行了交叉验证。论文谱图中的全部209个能级均在印刷图表的精度范围内被复现。强衰变、辐射、湮灭和电磁表格的复现结果，其中位数模型与论文比值介于0.97至1.06之间，且$1P$混合角与作者在1985年后修订的值一致。随着计算公开，模型自身的波函数可用于衰变振幅和结构可视化。该包及其教学材料和智能体可访问接口，使该模型成为实验问题和理论扩展的基线。
英文摘要：
The relativized quark model of Godfrey and Isgur (1985) remains a reference for meson spectroscopy four decades after its publication, yet despite its impact the calculation behind it has never been publicly available. I present an independent reproduction of the whole paper, released as the open-source Julia package GIModel.jl with companion packages for transition observables and for the comparison with the original. The published parameters are used without refitting, and the paper's three-stage harmonic-oscillator algorithm is cross-checked with an independent finite-difference solver. All 209 levels of the paper's spectrum figures are reproduced within the precision of the printed diagrams. The strong-decay, radiative, annihilation, and electromagnetic tables are reproduced with median model-to-paper ratios between 0.97 and 1.06, and the $1P$ mixing angles agree with the values the authors revised after 1985. With the calculation open, the model's own wavefunctions become available for decay amplitudes and structure visualization. The package, its teaching material, and its agent-accessible interface make the model a baseline for experimental questions and theoretical extensions.
