Flip the hidden pattern. Flip the developmental preference.
The original field favored the expansive direction. The exact negative of that field favored the reciprocal, compactifying direction.
Original field
q128 expansion-over-compactification polarity; 95% CI -0.055 to +1.054.
Sign flipped
The same field multiplied by −1; 95% CI -0.919 to -0.108.
Paired separation
11 of 16 families point in the same signed direction.
At q64 the paired sign separation is already +1.055 [+0.421, +1.841]. The polarity is created by development; it is not visible in the starting body.
One invisible redistribution, eleven geometric versions.
At the intervention instant, every condition has the exact same visible total-mass field, the same global channel balance, and the same perturbation energy. Only the spatial allocation between the two hidden material channels changes.
We compared the original field with its negative, three rigid rotations, two mirrors, and four eight-pixel translations. Each transform was independently energy-matched after it was applied. Maximum visible residual was exactly zero; maximum relative energy residual was 7.66×10⁻⁸.
The field is signed and anisotropic.
Sign
Negation reverses the polarity: +0.489 becomes -0.502. That is the cleanest result in the orbit.
Orientation
A 180° rotation remains positive (+0.352), while quarter-turns are near neutral. The operator has a twofold orientation.
Reflection
Mirror-x reverses the polarity (-0.384); mirror-y does not. The response is axis-sensitive rather than rotation-invariant.
The sign is quiet early, then becomes fate.
At q32 the two signs are still close. By q64 their developmental preferences have separated sharply. The effect softens at q96 and reappears at q128: not a monotone dial, but a signed influence on a nonlinear developmental trajectory.
The visible body begins the same. Its hidden allocation sends it elsewhere.
Expansive developmental direction
Compactifying developmental direction
Representative organism: serene-spiral-0219, source 63, maximize mode. These images show only the visible total-mass morphology at q128; the intervention itself is invisible at q0. The aggregate claims above use all 39 organisms and all 16 families, not this selected illustration.
This looks like an operator, not a texture.
A hidden compositional field can carry directional developmental meaning even when the visible organism, total mass, channel balance, and perturbation energy are held fixed.
What is now solid
The known field06 candidate has a causal signed geometry in this cohort. Sign inversion reverses its developmental bias, and rigid transforms alter that bias systematically.
What remains open
We have not yet shown that field06 is universal in fresh organisms, nor identified the microscopic flow mechanism that reads its orientation. This experiment tells us what kind of object to look for.
Next: put the original, its negative, the 180° survivor, and the mirror-x reversal into genuinely fresh developing organisms. If the signed geometry travels, we have found a reusable developmental coordinate.
