| abstract: >- |
| A 2x2 study (quantization regime x released model pair) of governed |
| routing quality for Gemma 4 12B (dense, same-base pair) and a 26B-class |
| MoE released pair on one RTX 5070 Ti: within-pair regime effects are |
| marginal and oppositely signed; the regime x pair interaction — an |
| exploratory single-run endpoint — is +0.030 with a stem-clustered 95% |
| CI of [+0.010, +0.052], concentrated in the volatile-current family; |
| and only 23-32% of temperature-0 outputs are byte-identical across |
| regimes against 100% same-configuration repeat determinism in all four |
| cells. The license field describes the paper and data; analysis code is |
