There is no single “composition code.” There are at least two control modes.
TO EXPAND
toward the expansive donor under the intact local map · 95% CI [3.3%, 86.6%]
Uniform: -0.058. Scrambled: +0.075. Neither has a clear positive interval.
TO COMPACT
toward the compact donor under a spatially uniform ratio · 95% CI [11.3%, 136.5%]
Scrambled is similarly strong at 73.8% [12.7%, 146.6%]. The precise donor map is unnecessary.
The invisible composition field is not merely “more information.” Its global balance can push a body toward compactification, while its local spatial organization appears necessary to guide expansion.
A quarter transplant already moves the future.
25% donor composition produced a 22.0% donor-direction displacement at step 128—about four-fifths of the full transplant’s mean.
The curve is not smoothly monotonic; these are nonlinear living dynamics, not a dial on a motor. But the fitted dose slope remains positive: +0.213 [+0.040, +0.398].
Every nonzero dose has a positive pooled interval at step 128. The system is highly sensitive well before a complete swap.
The two mechanisms separate as the body evolves.
EXPANSION
The intact donor map is the only condition whose step-128 interval is clearly positive. Erasing or scrambling its spatial arrangement removes that clean directional pull.
COMPACTIFICATION
Uniform and scrambled donor balance both drive large compact-donor motion. Exact local alignment is not required; the global composition state is already causal.
This is a developmental asymmetry, not just a stronger and weaker version of the same effect.
One organism can contain both a field-like instruction and a scalar-like control knob.
MAP
Local channel arrangement can encode where expansion should unfold.
SET-POINT
Global channel balance can place the organism in a compactifying dynamical regime.
SENSITIVITY
Even partial composition changes can redirect later morphology without changing visible matter.
This is closer to the kind of hidden organization we were looking for: a pre-morphological state whose structure does not merely predict a future form—it helps select the future trajectory.
The full-field body still generally remains recognizably its host. We are identifying control coordinates inside an organism, not swapping organism identity wholesale.
Map the bifurcation surface.
The next experiment is not another yes/no. It is a map of the organism’s hidden control surface.
