# COUCH Data Magnetic-Domain Comparison
|
|
|
|
This comparison runs the same byte-signal to magnetic-domain transfold used for
|
|
`enwik8` against the local COUCH JSON data bundle.

|
|
COUCH bundle:

## Read
|
|
|
|
The COUCH bundle returns the same magnetic-domain shape class but in a smaller,
|
|
cooler regime:
|
|
|
|
```text
|
|
COUCH mean heat loss is about 0.239, versus enwik8 1 MiB at about 0.973.
|
|
COUCH mean remanence is higher, about 0.889 versus 0.844.
|
|
COUCH mean susceptibility is lower, about 0.569 versus 0.746.
|
|
```
|
|
|
|
That suggests COUCH data is more memory-like and less transition-agitated under
|
|
this transform. In routing terms, COUCH looks like a compact high-remanence
|
|
surface that should prefer dictionary/state reuse, while `enwik8` looks like a
|
|
larger high-transition surface that needs more boundary-aware shaping.
|
|
|
|
Claim boundary:
|
|
|
|
This is a byte-statistical magnetic-domain analogue. It supports routing and
|
|
stress-test comparisons only; it is not a proof of compression improvement.
