Describe the common architecture and functions of the treaty bodies.

The UN's double machinery: the Charter-based organs (working from the UN Charter's own authority — the Council, the UPR, the special procedures) and the treaty-based organs (the committees created by each treaty — the states-parties' creatures). Beside them: the HighCommissioner for Human Rights (OHCHR) — the system's coordinator and voice; the GeneralAssembly and ECOSOC's historic roles; and the mainstreaming mandate (human rights in all UN work — the specialised agencies' faces: the ILO's standards, UNESCO's, WHO's — International Institutions' terrain, LAW5405). The design's logic: the world has no human-rights court of general jurisdiction — so the system works through dialogue, naming and assistance (the reports, the reviews, the visits) rather than judgment.
