This paper presents PC-MLRA (Proof-Carrying Medical-Legal Rights Advisor), a deterministic system designed to provide structured awareness of patient rights and professional ethics in medical contexts. The system maps user queries to legally grounded responses through a fixed, rule-based pipeline without machine learning or generative language models. Responses are generated using predefined templates linked to a static legal knowledge base derived from the NHRC Charter of Patients’ Rights (2019) and the IMC Ethics Regulations (2002). Each output can include a structured proof trace that records the matched intents, activated clauses, and template selection, enabling auditability and reproducibility. The system is evaluated with respect to determinism, legal clause coverage, trace completeness, and safety under ambiguous queries.
