Tier 0. Reordering Settings->StratePool in the editor used to change every world in the game, because Initialize Fisher-Yates shuffled the array in editor order. The pool is now sorted by stable soft-asset path before the shuffle, so the layout is a pure function of (seed, pool contents as a SET). The selection algorithm itself is untouched -- same Fisher-Yates, same cycling, same FixedStrates handling, same Z ranges. Sorting by pointer would have looked right and been load-order dependent, which is the trap here. GeneratePassages walked one sequential FRandomStream across every strate, so changing an early connection count shifted every later passage. Each draw is now a salted VoxelHash of (seed, boundary index, connection index), with the distributions preserved exactly -- ToFloat01 returns [0,1), so Lerp(Min,Max,t) reproduces FRandRange precisely. Codex implemented it and caught a real flaw in my spec: I asked for a test that permutes the pool and asserts the passages match, but once the layout is order-independent that test cannot fail whether or not the passage fix works -- the layout comes out identical, so even the old sequential stream would agree. It added the perturbation that actually bites: change an early connection count and verify every later boundary keeps its own values. It also contradicted me on passage type being randomly drawn. It isn't, and it preserved that. Built VoxelMEditor clean, then ran the suite headless: 16 succeeded, 0 failed, 0 not run. That also closes the thread OPSTACK-HANDOFF.md left open --4d33321and91585eawere built but never re-verified, and both acceptance conditions are now met: violations 0 everywhere (12 of 40 TunnelNetwork tiles proved over 15972 brute-forced voxels), all equivalences green. No revert needed. Expected: every seed now lays out differently than before. Accepted, pre-content-lock.
