The Trajectory Engineering Papers — Series Roster and Persistent Identifiers (Roster Note v1.0)

Abstract

The single authoritative statement of the roster of The Trajectory Engineering Papers, a numbered working-paper series specifying Health 4.0 and health trajectory engineering. Papers I, III, and IV each carry a roster written at the time of their deposit, and the roster changed between deposits (May 2026 and August–September 2026); this note supersedes those roster sections, records the persistent identifiers (Zenodo and SSRN) of every deposited paper, gives a concordance mapping each printed cross-reference to its current paper number, lists companion works outside the numbered series, and states the versioning convention. The current roster: I Prospectus; II The Framework for Closing the Loop; III Health 4.0: The System of Care; IV Health 4.0 and the End of Zero-Sum Healthcare; V Health 4.0 and the Health Trajectory Benefit: A Definitional Specification (in preparation); VI The Longevity-Short Balance Sheet (in preparation); VII The Chronic Disease Dividend; VIII The Health Trajectory Benefit: Actuarial Specification; IX Global Translation; X Trajectory Engineering Beyond Health. This note is re-issued as a new version whenever the roster changes; the concept DOI always resolves to the current roster.
