This leads to Physical Hallucination: the generation of syntactically correct solvers that faithfully execute physically invalid laws. Here, we introduce a Neuro-Symbolic Generative Agent that functions as a cognitive supervisor atop traditional numerical engines. By encapsulating physical laws into modular Constitutive Skills and leveraging latent intrinsic priors, the Agent employs a Chain-of-Thought reasoning workflow to autonomously validate, prune, and complete physical mechanisms. We demonstrate this capability on the challenge of thermal pressurization in low-permeability sandstone. While a standard literature-retrieval baseline erroneously predicts catastrophic material failure by blindly adopting a rigid \"undrained\" simplification, our Agent autonomously identifies the system as operating in a drained regime (Deborah number De &lt;&lt; 1) via dimensionless scaling analysis. Consequently, it inductively completes the missing dissipation mechanism (Darcy flow) required to satisfy boundary constraints, predicting a stable stress path consistent with experimental reality. This work establishes a paradigm where AI agents transcend the role of coding assistants to act as epistemic partners, capable of reasoning about and correcting the theoretical assumptions embedded in scientific data.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='cs.DB'/>\n    <published>2026-03-10T14:56:36Z</published>\n    <arxiv:primary_category term='cs.DB'/>\n    <author>\n      <name>Yue Wua</name>\n    </author>\n    <author>\n      <name>Tianhao Su</name>\n    </author>\n    <author>\n      <name>Rui Hu</name>\n    </author>\n    <author>\n      <name>Mingchuan Zhao</name>\n    </author>\n    <author>\n      <name>Shunbo Hu</name>\n    </author>\n    <author>\n      <name>Deng Pan</name>\n    </author>\n    <author>\n      <name>Jizhong Huang</name>\n    </author>\n  </entry>"
