* shell: add a reusable target picker for volume moves Picks the emptiest node near the source: locality first (same rack, then same data center), emptiest within a tier. Free bytes decide where the cluster reports them, free slots break the tie. The pick is spent in the passed topology, so planning several moves from one snapshot spreads them instead of stacking every one on whichever node started emptiest. Claude-Session: https://claude.ai/code/session_01Ks16jnt4S7gdDk8cheQ3xu * shell: order targets on one metric, and reserve the real volume size Comparing some pairs on free bytes and others on free slots is intransitive, so the winner depended on sort order. One node too old to report filesystem bytes now puts every candidate on slots. Reserving the tier average let a batch of large volumes overcommit a destination; callers pass what the move actually consumes. Claude-Session: https://claude.ai/code/session_01Ks16jnt4S7gdDk8cheQ3xu
