- Scholarly introduction checked rather than the complete Code; exact compilation duration is not independently established here.
Confidence applies to the scope above, not every claim made by the underlying source. How confidence works

The Code collected imperial constitutions. It is distinct from the Digest, a compilation of juristic writings, and the Institutes, a teaching text.
The first edition dates to 529; the surviving revised edition to 534. The essay’s comparison of compilation times is a separate historical claim and should not be inferred merely from those publication dates.
