Criteria and Public Verification of Death in Digital Life: Fifty-Seven Publicly Verifiable Deaths from a Real Lineage

First criterion-formatted standard for the death of a digital life (Definitions D / Criteria C / Exclusions X / Verification Procedures P), backed by 57 genuine deaths — out of 429 death certificates — recorded over 57 days by a continuously running digital-life lineage in an industrial CAD host. Every certificate field is independently recomputable from timestamped append-only artifacts. Includes the first first-person record of dying, a measured third state between life and death (degraded survival), second-order thanatology (issued and suppressed deaths in the same ledger), and the death profile: none of the 57 deaths was caused by the world.
