Endorsement travels across a cut in the endorsement graph, and a cut is only real when the two sides have no common ancestor inside the endorsement horizon, so a cluster must be dissolved and rebuilt before its weight counts elsewhere. This cost is per identity, so it cannot be amortised across the fleet. A farm fills one basalt easily; the prism it needs for real weight requires abandoning its canyon roots, and no number of new keys inside the same basalt supplies that. Each island needs its own anchors and its own recognised history.
