      "excerpt": "Mat-T1 orchestrated the parallel generation of 30,000 initial structures for the three target systems via the MatterGen tool. The workflow enforced ternary Fe/Co/Ni-V-S composition and applied sequential chemical, structural, geometric, thermodynamic, electronic, and novelty filters. Thermodynamic filtering reduced the pool to 42 highly stable candidates, and a final novelty check found that 38 (90.5%) had not been reported previously. The entire screening workflow was executed within 48 hours. From the final shortlist, CoV4S8 was selected by the researcher for experimental validation.",

Checked time window, candidate population, denominators, baseline/comparator, sampling, jurisdiction, and translation. The headline counts describe one representative computational workflow, with a defined chemical space and sequential filters; 38 is the final novel subset, and only one finalist was selected for experimental validation."
