Context
A named imperial marriage is a continuity path under Marcus’s still-living authority. Shared household with Faustina’s circle remains.
Commodus’s documented role is bounded by other offices and collaborators named in the sources below.
Livius dates the marriage to 178 under Marcus. Crispina’s later exile and death are a neighbouring hostile-source row, not this wedding. Dio and later lives are literary carriers, not a wedding register.
Why it matters
The 178 marriage is a continuity path of high confidence on the heading in standard chronologies, none on a unique dynastic stability coefficient.
