Appendix: Evidence Map and Verification Queue

A note on this appendix. What follows is a working, deliberately incomplete list of the research on which the empirical claims of this volume rest. We offer it in the spirit named throughout the book: not as proof, but as the ground a doubter is entitled to stand on before deciding what to believe. Three honesties belong at the top. First, this list is partial: it reflects what we have found, not the whole of what exists, and we expect readers to extend and correct it. Second, these studies establish correlates and mechanisms (that presence has measurable physiological signatures, that the body's signals track regulation and emotion, that being understood and coordinating well are real and measurable), not that the full Currency of Presence has been built or validated. The validation studies this book calls for are precisely what is still missing; that is the point. Third, we invite adversarial reading. Put these citations in front of a capable AI and ask it to check our claims against the literature, to find where we have overreached, to surface what we have left out. A thesis that cannot survive that scrutiny does not deserve belief.

Bibliographic details vary in completeness; entries without full metadata should be treated as research leads rather than settled citations. Descriptive notes are summaries, not quotations from the cited works.
