Preserve the first cap64 score before the second strategy finishes

Constraint: The cap64 run has only produced the high_energy leg so far, so any larger conclusion must wait for hybrid and the final report
Rejected: Wait for report.json before checkpointing | Would lose the verified cap64 high_energy score and the proof that execution has already switched into the hybrid branch
Confidence: high
Scope-risk: narrow
Directive: Do not compare cap64 strategy winners until both legs and the final report land; treat the current 0.625 high_energy score as an intermediate checkpoint only
Tested: Verified high_energy eval.json reports num_queries=32, top1=0.625, topk=1.0; verified progress.json records the same result; verified the active process has switched to the hybrid smoke-local branch and report.json is still absent
Not-tested: Final cap64 hybrid metrics, final report.json, and any cap64-based strategy conclusion
