What this check doesn’t establish
- These are the emperor’s claims, not independently audited production statistics. Subcommittee reconstruction and manuscript transmission were not verified; removed assertions of a ten-year deadline and sole Western manuscript.
Confidence applies to the scope above, not every claim made by the underlying source. How confidence works

The imperial preface reports nearly two thousand books and three million lines of material reduced to about 150,000 lines. It celebrates completion in three years when ten had seemed scarcely sufficient. That is not the same as documenting a formal ten-year deadline.
The essay’s “sharded corpus” analogy depends on a modern scholarly reconstruction of the commission’s working groups, which was not checked here. Neither the preface nor this audit establishes the essay’s account of the Digest’s later manuscript transmission.
The numbers should be attributed to the imperial preface rather than presented as independently audited measurements.
