In the 1348 plague year Boccaccio suffers household bereavements in Florence as later lives report; the plague is context, not his act
The Decameron book remains a separate instrument dated to completion, not to 1348 mortality. In the causal graph this event strengthens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — a worsening welfare path.

Context
He did not cause the plague. The Decameron book remains a separate instrument dated to completion, not to 1348 mortality.
Giovanni Boccaccio’s documented role is bounded by other offices and collaborators named in the sources below.
Britannica places him in Florence during the 1348 ravages. Lives report deaths of father and stepmother in the plague neighbourhood.

What the sources establish
Britannica records Boccaccio in Florence in 1348. Decameron Web independently treats the plague year as a biographical hinge.
Giovanni Boccaccio did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. Plague is context; do not date the Decameron to 1348 mortality. No fabricated certainty on every relative.
