BU80 advances a settlement-surface judgment: the real world is not a surface of explicit display, but a surface of conditional settlement. It identifies a deeper fact: reality is not a showroom, but a dynamic field of settlement. It addresses how “latent structures” are transformed into “explicit reality.” This paper develops BU80|Conditional Settlement of New Standing Positions under B_U as a structural account of how new standing positions acquire admissible existence within a changing reality. Its central claim is that the establishment of new structures in reality does not arise from pure randomness, local microscopic fluctuation, formal equivalence, or subjective naming alone. A new standing position arises when a retainable residual structure passes through a chain of persistence, connection, cost payment, environmental admissibility, feedback, and settlement. The paper therefore treats new standing positions as conditional settlement results rather than automatic displays of all possible forms. BU80 introduces the universal co-admissive medium as the full-factor connective carrier of total reality. This medium is not a particular object, material, field, or local channel. It is the carrying structure through which objects, relations, conditions, residual structures, and transition paths may obtain connectability, persistence, trialability, return-writing, and settlement qualification on the same settlement surface. Reality does not unfold every possible standing position at once. Many structural positions first appear as residue, weak signal, noise, anomaly, seed-stage form, or unclosed readout. Their standing depends on boundary conditions, coherence windows, environmental carrying capacity, gradient admissibility, feedback chains, friction cost, and settlement paths. The paper then defines the weak persistence morphism p^w as the structure that preserves traceable continuity through change. It allows retainable structures to continue across disturbance, failure, environmental transition, feedback, and nonzero cost without requiring strong identity or zero-friction equivalence. Weak persistence morphism therefore explains how a structure can remain trackable across windows while still undergoing transformation, trial, selection, and reconfiguration. BU80 also refines soft link and related terms. Soft link does not mean a merely weak connection. It denotes a low-impedance, low-entropy, composable, transferable, testable, and settleable linkage that follows the universal co-admissive medium rather than forcing a rigid coupling. In this sense, soft links may be strong or weak, near or distant, explicit or implicit. The concept can be further sharpened through translinkage relation and translinkage gradient flow, where a latent relational convertibility becomes activated and directed toward a possible new standing position. The friction-cost functional is then introduced as the total cost term required for soft links and weak persistence morphisms to execute in reality. It includes state-transfer cost, structural-matching cost, resolution-conversion cost, coherence-maintenance cost, information and energy exchange cost, constraint-compatibility cost, residue-bearing cost, risk cost, information-update cost, and settlement-readout cost. Every real soft link carries nonzero friction cost. The paper uses the Mariana Trench as an intuitive example. Extreme pressure, darkness, temperature, chemical gradients, nutrient constraints, and ecological feedback form a special environmental window. Retainable biological structures may persist, adapt, and enter new population standing through weak persistence, soft linkage, environmental selection, and settlement. The final judgment is that new materials, new meanings, new biological adaptations, new organizational forms, and new economic windows emerge through conditional settlement: the universal co-admissive medium carries the possibility, weak persistence preserves continuity, soft links expose transformable relations, friction cost records reality expenditure, and settlement grants the new standing position.
