Required update. Post-H2 (DAA ≥ 38,951,445) the PoM tier set was reindexed (Qwen3-1.7B at tier 0), so older miners stamped the wrong tier and the node rejected their blocks (BadWeightPath). v0.6.4 sends the correct H2 tier index and reports version 0.6.4 to the pool.
Lines (pick your OS tarball; verify with the matching SHA256SUMS): modern (CUDA 12.x, R575+ — 50xx/A100/30xx/etc), legacy (CUDA 12.4, R550+), pascal (sm_60, GTX 10-series / 1080 Ti — run with --cpu-inference). Adds --very-light (Qwen3-1.7B) + 70B Q2_K_L for --very-high. AMD/Windows distributed separately.
