Inclusion Criteria: * Age 18 to 75 years at the time of consent. * Histologically confirmed malignant pleural mesothelioma or malignant peritoneal mesothelioma; unresectable, recurrent, metastatic, or refractory disease. * Prior receipt of at least one standard systemic regimen for mesothelioma, or documented ineligibility, intolerance, or refusal of standard therapy considered reasonable by the investigator. * Central biomarker confirmation of MSLN-positive tumor cells and FAP-positive tumorassociated stroma at protocol-defined thresholds. * At least one measurable or evaluable lesion by cohort-appropriate imaging criteria. * ECOG performance status 0 to 1. * Adequate bone marrow, renal, hepatic, coagulation, cardiac, and pulmonary function to undergo lymphodepletion and locoregional cell infusion. * Safe procedural access for intrapleural or intraperitoneal administration, as applicable. * Recovery to Grade 1 or better from prior anticancer therapy toxicities, except alopecia, stable neuropathy, or controlled endocrine replacement. * Life expectancy of at least 12 weeks. * Negative pregnancy test for participants of childbearing potential and agreement to use protocoldefined contraception. * Ability to understand and sign informed consent Exclusion Criteria: * Active or untreated CNS metastases, leptomeningeal disease, or uncontrolled seizures. * Uncontrolled bacterial, fungal, viral, or mycobacterial infection, including empyema, active pleural space infection, peritonitis, or uncontrolled HBV, HCV, or HIV infection. * Autoimmune disease requiring systemic immunosuppression within 14 days before lymphodepletion, or prednisone equivalent greater than 10 mg/day. * Clinically significant cardiovascular disease, uncontrolled arrhythmia, unstable angina, recent myocardial infarction, or other condition judged to increase infusion risk. * Severe interstitial lung disease, baseline oxygen requirement, or other pulmonary compromise making pleural therapy unsafe. * Bowel perforation risk, uncontrolled bowel obstruction, uncontrolled ascites, or any abdominal condition that makes intraperitoneal infusion unsafe in the peritoneal cohort. * Prior gene-modified cell therapy directed against MSLN or FAP within the protocol washout period, or active graft-versus-host disease after prior transplant. * Need for concurrent systemic anticancer therapy other than protocol-permitted supportive care. * Pregnancy or breastfeeding. * Any medical, psychiatric, social, or logistical condition that, in the investigator's judgment, could compromise safety, compliance, or interpretability of study results.
