## What Bejan Saw
Bejan examined flow systems under finite time and finite size constraints. He identified the generation of configuration as a physical phenomenon. The work grounds design evolution in thermodynamics.

## Core Results
The second edition incorporates the constructal law. Flow architectures evolve to provide greater access to currents. Patterns include tree-shaped networks and branching structures. These arise in heat transfer, fluid flow, and cooling systems.

## Exact Passages and Citations
The constructal law appears as: "For a finite-size flow system to persist in time (to live) it must evolve with freedom such that it provides easier and greater access to what flows." This statement is referenced in the 1997 edition from 1996 papers on conducting paths. The book links entropy generation minimization to finite-size systems.

## Convergence Patterns Evidenced
The text addresses flow networks. It shows branching and symmetry in engineered and natural systems. Scale invariance appears in optimized tree structures. Bounded chaos and memory in flow paths receive treatment through configuration persistence.

## Relation to OIP/GRAIN Synthesis
The work supplies mechanistic grounding for energy flows that produce structural patterns. It aligns with the Ladder step from flow to structure. Distance remains partial. The synthesis extends to memory, life, and mind layers. Bejan stays within inanimate and animate flow systems.

## Honest Limits and Disconfirming Edges
No direct treatment of the Mirror Layer or reader-in-system recursion exists. Reductionist accounts of pure entropy increase without configuration generation stand as separate. The law applies to finite-size systems and does not claim universality beyond that scope. Primary sources remain the 1996-1997 papers rather than later expansions.

## Mechanistic Claims in Detail
Finite-time thermodynamics optimizes access routes. Tree networks minimize resistance under volume constraints. This holds in heat generating volumes cooled by conducting paths. Claims derive from mathematical modeling of flow architectures.
