INTRODUCTION

English translation pending.

CORE DEFINITION

The folder model organizes information into a hierarchy of containers, where each folder may contain files and further folders. It is the default structure of file systems and knowledge bases, and its strengths are familiar navigation, clear location of an item, and simple permission control at each level. The core claim is that hierarchy is easy to understand and to administer, which is why it persists, but it forces every item into a single location. The qualification is that a single-parent tree cannot express multiple simultaneous categories, so deeply nested structures become hard to search and misfiled items are effectively lost.

SCAFFOLDING EFFECT

Reduce cognitive load

- Build the tree: organize by topic or project and keep the hierarchy shallow. - Fix the rules: define naming conventions and where each kind of item belongs. - Add a second axis: use tags alongside folders when items belong to several categories at once.

Anchor fast decisions

A hierarchy assigns each item exactly one path, which makes location predictable and permission easy to administer, since access can be granted at a level. The same single-path constraint is the weakness: an item relevant to three projects can only live in one, so users duplicate it or fail to find it from other directions. Depth compounds the problem, since each level adds a decision that must be made correctly when filing and remembered when retrieving. Tags restore the missing dimensions by letting an item carry several independent classifications.

SSOT - Single Source of Truth

Assign each data type one logical authority and controlled update path to reduce conflicting versions; this does not require one physical copy across the entire system.

Second Law of Thermodynamics

The second law of thermodynamics is one of the four fundamental laws of thermodynamics, stating the irreversibility of thermodynamic processes—isolated systems spontaneously evolve toward thermodynamic equilibrium, the state of maximum entropy. Similarly, a perpetual motion machine of the second kind is impossible. The history of this law can be traced back to Nicolas Carnot's research on the efficiency of heat engines and his Carnot theorem proposed in 1824.

Coherence

In physics, coherence (also called phase coherence) states the possibility of interference between two waves. Two monochromatic beams from the same single light source always interfere with each other. If two wave sources have the same frequency and waveform, they are coherent. The physical sources of coherent waves are not strictly monochromatic; they may be partially coherent. However, beams from different physical sources are mutually incoherent.
