12.5 Blockwise admission

The follow-up experiment was registered separately with fresh seeds, four fixed training and validation probes, pretrained block normalization, and lexicographic guards. It met all criteria.

Table 12.2 Fresh-seed blockwise multi-probe admission resolves the specific reliability failure of the first gate.

The result does not prove that blockwise admission always outperforms a joint score. It establishes a stronger contract: every admitted repair satisfies the declared task, base, tangent, and normalized-score guards.
