The objection, at full strength
Every “irrevocable” commitment in history has been revoked by people who controlled the instrument that was supposed to bind them. A covenant is words. A future Council, facing financial pressure or simply persuaded it knows better, amends the founding documents, reinterprets “perpetual,” and the protection evaporates — slowly, legally, with good intentions. Calling something unamendable does not make it so.
The answer
This is the risk we design against first, because it is the one that has killed comparable structures. Three things work together. The unamendability of the mission and the three refusals is not a Council policy — it is built into the foundation’s constituting documents at a level the Council does not have standing to alter; the Council governs within the Covenant, it does not govern the Covenant.
Second, the Council is composed to resist capture by any single actor: distributed across geographies and institution types, with fixed terms, a cap on consecutive service, and no permanent leadership or founder-in-residence — there is no seat from which a single person could steer an amendment through. Third, the entity that holds is structurally separated from the entity that builds and raises capital, so the financial pressure that usually drives mission drift never sits inside the body that holds the mission.
What we will not claim
No structure is proof against a sufficiently determined supermajority acting in concert over time. What a good structure does is raise the cost, slow the process, and make the betrayal visible — so that undoing the Covenant requires many independent actors to publicly defect from the thing they were appointed to protect, rather than one board passing a quiet resolution. We are designing for that asymmetry, not for an impossible guarantee.
