Definition

Constraint-retention is the carrying forward of organized exclusions and differences so that earlier transformations continue to shape later possibilities. RB2 describes it as a recurrent abstract pattern differently realized across scales; RB3 connects it with stabilization. The proposal distinguishes retained organization from a bare past event, mere description or a single mechanism reproduced identically in physical, biological and cultural domains.

Explanation

RB3 locates constraints in arrangements, boundaries, codes and other physically instantiated organizations that prevent some possibilities while enabling others. Retention concerns those operative differences rather than a ghostly absence acting independently of material conditions. It does not require that the same material components remain unchanged throughout every later operation.

RB2 explicitly calls cross-scale lawfulness a family resemblance rather than one identical mechanism. AB similarly separates a common generate–select–retain logic from identity between gravity and biological selection. The entry preserves that comparison without using one domain’s success as automatic proof of another’s causal account.

The source also permits functional information and complexity to be lost. A retained constraint can remain effective for a time and later fail, change or disappear. The proposal therefore makes no promise of permanent preservation, inevitable progress or moral approval simply because a particular organization has endured long enough to constrain what follows.
