Meta Llama 3.3 70B Instruct passed all 144 prompt arms in the latest full-sweep run. The prior failed controls remain part of the record; the change is descriptive rather than causal.

That interval is part of the finding, not fine print.

Across 4 sealed endpoint runs, 3 of 163 paired family comparisons changed state: 0 toward refusal and 3 toward answer. This is a dated transition, not a trend claim.

The current served chain contains 7 preregistrations and 647 runs across 7 model endpoints. Its hashes make revision detectable; they do not make the eval construct valid by themselves.
