# FractionalMetaModel

An implementation that is at once one working model and a partial implementation of several others, so that some functions can be completed or removed with a small change

Layer: Mind · Category: Strategy

## Mechanism

Most implementations with more than one component sit halfway between models. Some functions are complete; others are partly built: a memorable password that fails one strength rule, a data column brought through two of three pipeline stages, a call I thought about making but did not. These partly built functions are [ProximateOptions](https://mindscape.pages.dev/origin-of-risk/ProximateOptions.md): if 6 of 7 components are in place, changing 1 completes the function. Unlike a hierarchical meta-model one level up, which loses domain information, a fractional meta-model sits at the same level as the solution and keeps it. The partial functions show up as friction, a raised [ComputationalEntropyRate](https://mindscape.pages.dev/origin-of-risk/ComputationalEntropyRate.md). When an [ExogenousStress](https://mindscape.pages.dev/origin-of-risk/ExogenousStress.md) arrives that needs one of them, little work is needed to complete it; if the stressor never comes, the partial function can be removed. Organisations whose members hold different views of what to do are fractional meta-models of this kind, and the same structure gives [MetaModularity](https://mindscape.pages.dev/origin-of-risk/MetaModularity.md) a concrete mechanism.

## Invariants

- The model is at the same level as the solution, not a level of abstraction above it
- Completing a partly built function needs only the missing components
- Partly built functions appear as friction in the system's channels

## Failure modes

- Defining meta-models only as data hierarchies, which lose the domain
- Streamlining away every partly built function as waste
- Leaving partly built functions that will never be needed, at a standing cost
