An invisible internal rewrite changes what the organism becomes.
The perturbation did not add mass, move mass, alter the visible body, or change global channel balance. It changed only which hidden material occupied each visible location.
Immediate reorganization
Radius shift after only 32 transitions; 95% family interval -0.116 to -0.056.
Maximum compaction
At +128 steps, 15 of 16 families compacted relative to their untouched futures.
Long memory
Visible-field distance at +512 steps. The average radius recovers, but the future does not return to the untouched trajectory.
First the body contracts. Then the difference becomes history.
The rewrite produces a coherent transient: slightly more mass, smaller radius, and broader occupation of the four spatial quadrants. The radius effect peaks around +128 steps and relaxes. Yet the full visible-field distance keeps growing—from 0.239 at +32 to 0.327 at +512.
One visible beginning. Several real trajectories.
Representative source 25, chosen mechanically as the organism closest to the cohort-median field06 original-versus-negative divergence at +128. The q40 panel is rendered from the exact two-channel state patch by summing the channels. All seven intervention states have the identical summed field byte-for-byte. Aggregate effects use all 64 organisms; these images are illustration, not selection evidence.
The susceptibility travels. The word mostly does not.
The previously discovered field06 operator was not uniquely powerful in these fresh q40 organisms. A decoy hidden field produced nearly the same broad developmental reorganization.
General causal plasticity
Mean visible-field distance at +128 across all six hidden rewrites; every family moved away from intact.
Field06 family − decoy
Radius difference at +128; 95% CI -0.098 to +0.047. Broad morphology does not privilege field06.
Signed specificity
Field06 sign contrast minus decoy sign contrast at +128; 95% CI -0.111 to +0.072.
This changes the target. There may be no universal magic texture. The organism appears to have a private hidden coordinate system: the ability to be redirected is shared, while the meaningful direction must be learned from its own development.
Visible morphology is an incomplete causal state.
Two states can be visually identical and globally composition-matched, yet have systematically different futures because their internal organization differs.
What we now know
Hidden composition is not decorative bookkeeping. It is a causal substrate that stores developmental alternatives before those alternatives are visible in morphology.
What becomes possible
Instead of asking whether one imported Φ-derived field predicts one event, we can search for the organism-specific hidden direction along which its future repertoire opens, closes, branches, or commits.
Learn each organism's own developmental tangent—then push with it or against it.
Observe a short untouched prefix. Infer the hidden compositional direction the organism is naturally moving. At q40, apply equal invisible doses along that direction, against it, orthogonal to it, and through a phase-scrambled decoy.
Along
Does development accelerate, open more futures, or cross a morphological transition earlier?
Against
Does the organism stall, reverse, lose identity, or fall into a different basin?
Orthogonal
Does arbitrary hidden motion merely perturb, while the native tangent carries specific developmental meaning?
That is the direct route back to the Levin question: detect an information-geometric direction in an early state, intervene on it before the organism changes shape, and see whether it controls the emergence of future organization.
