Abstract

This paper presents SCIR-TG-MT, our primary submission (ID 44) to the unconstrained track of the WMT 2026 General Machine Translation shared task. The system covers ten translation directions using DeepSeek-V4-Pro and STRIDE (Structured Translation with Risk-Informed Directional Execution), an OpenCode translation skill. STRIDE converts source-side evidence and task instructions into a translation contract, an execution route, generation constraints, and selected checks. On five WMT25 development directions, STRIDE raises average SacreBLEU from 31.24 to 31.80 and COMET-22 from 83.61 to 84.17. A cumulative ablation on three directions separates the effects of routing, controls, and validation.
