The reason is item 1 of the MOF/MIIT Operating System Government Procurement Requirements Standard (2023 edition), verified for this briefing in the PDF from gks.mof.gov.cn: a starred, non-scoring indicator requiring that the operating system be same-source compatible with ARM, LoongArch, MIPS, SW64 and x86 CPUs. MOF's own transmittal notice makes starred indicators substantive requirements that cannot be awarded points, only met or failed. HarmonyOS V1.0 was, in January 2026, the first and still the only desktop operating system certified at Security-Reliability Level II — and it still failed the first page of the form. A WeChat practitioner essay published on 2026-10-28 supplies the explanation from the vendor side: four walls — core architecture, ecosystem, procurement rules, commercial control — and the decisive one is that a distro built on Huawei's core would turn an independent systems vendor into a customisation subcontractor whose API cadence is set by a competitor. The institutional point is precise: a rule that scores can be met by improving the artefact; a rule that is starred and non-scoring can only be met by changing the artefact's architecture or the vendor's identity. China's procurement form has made the second kind a gate, and a supplier that has just won the safety contest is the case that reveals what such a gate is actually selecting for.
