I23g. CONTINUATION OF SYSTEM VIABILITY: A CROSS-DOMAIN COMPARISON OF RECOVERY CRITERIA AND THE SUBSEQUENT VIABLE CYCLE

This paper presents a comparative conceptual and operational study of criteria for system recovery and continuation across 15 analytical domains. It draws on version 3.2 of an accumulating research registry containing 79 source records, together with checks of the availability and structure of selected datasets. The registry is a heterogeneous working corpus, not 79 independent experiments or an exhaustive systematic review. Continued existence, preservation of a selected function, recovery, adaptation, and capacity for subsequent recovery are distinguished. Vitological formalization connects a completed E_VSA cycle with a nonempty set of admissible future trajectories C_V and the possible realization of the next cycle. A nonempty C_V means that an admissible continuation exists within a specified model; it does not guarantee its actual realization. RRR is treated as a candidate characteristic of the capacity for subsequent recovery retained after a specified history. Environment, resources, external assistance, recovery cost, and consequences for the associated whole are considered separately. For human systems, Aw–Con–CON is formulated as a candidate mechanism of recognition, alignment, and coordination that must be measured independently of the future outcome. The outputs are a comparative map of criteria, data-sufficiency rules, and a program for testing added information. Under the current documentation, 52 records provide part of the required data and 27 support the definition of recovery and comparison of approaches; none has yet been admitted to a full RRR test. Individual files for 13 participants in one repeated-sprint study were inspected. This structural check does not establish RRR as a distinct measure. Viability efficiency is introduced as a candidate efficiency characteristic with domain-specific conditions of application. Its numerical operationalization, normalization, and evaluation of a common scale are reserved for separate work. This paper does not establish an independent universal RRR quantity, its unit, or superiority over existing reserve measures.
