Scope
Pre-search nomination: bounded preservation of a defined quantum information feature and recurrence of a collective spin observable under specified transformations; distinguish finite experimental endurance from unlimited persistence. The row specifies no actual system, feature, duration or programme mechanism, so examples assess its existential content only.
Uncertainty
Choosing a particular system, feature tolerance and timescale remains necessary for any commissioned test. That operational choice is open; the occurrence of bounded feature endurance is already evidenced. Biological homeostasis may preserve a statistical relation across a lineage rather than one organism’s complete state [S57].
