[2026-09-17] The v2 voice floor is now PAIRWISE, and it retroactively passes lv-bronte.

⭐⭐ The v2 voice floor is now PAIRWISE, and it retroactively passes lv-bronte. lv-bronte's ckpt475 shipped as a voice-axis FAILURE at +0.193 against a 0.251 floor contributed entirely by ckpt925 — a third arm nobody was shipping, on one outlier seed. Scored against the arm it was actually compared to the floor is 0.091 and it clears at 2.1x. The rule was changed prospectively, pre-registered for lv-hemingway before any Hemingway number existed, on an argument independent of the answer: the sampling variability of a difference A−B depends on A and B, never on a third arm C. The previous session found the defect and deliberately declined to exploit it; this follows from fixing it. lv-hemingway passes under both rules, so its verdict does not lean on the change. Caveats amended append-only in the compose, the NFS README and the gate record. Commits 0bb4938 2e9b118.
