Run 2,007
One admitted validation history row. Whole-run result and per-cell verdict remain separate.
Comparison operands were derived by a writer that verified the complete original raw census. Public readers authenticate this derived view, not private raw bytes. Only recorded cells are shown; the original failed or incomplete run status is unchanged.
Retained validation row
Current ledger record means this is the terminal row after applying the ledger correction chain for this run id. It does not describe code age.
