The same intervention axis reveals two morphogenetic grammars.
EXPANSION LANGUAGE
Intact pattern to full phase scramble. Fine-only: +0.056. Smooth σ4: +0.537. Smooth σ8: +0.608.
COMPACTIFICATION LANGUAGE
Intact pattern to full phase scramble. Fine-only: +0.379. The direction survives destruction that erases expansion.
These are reciprocal futures of the same organisms, under exactly matched perturbation energy. The asymmetry is in the developmental code itself.
Destroy relational phase and expansion disappears.
At 75% phase disruption, expansion falls to +0.041 and is -0.251 below intact [-0.491, -0.016]. Compactification remains +0.567.
Each dose uses an independent deterministic phase realization, so this is a dose-by-distribution curve rather than a single path to one scrambled endpoint. Its direction is nevertheless striking: expansion erodes; compactification does not.
Expansion lives broadly. Compactification also survives in the fine structure.
COARSE EXPANSION
Smoothing to σ4 or σ8 retains—and on average amplifies—the expansive direction. Fine-only is +0.056, -0.236 below intact [-0.461, -0.066].
MULTISCALE COMPACTIFICATION
Fine-only remains +0.379 [+0.021, +0.725]. Compactification can be carried without the broad phase-aligned map expansion needs.
The receiver reads direction and orientation too.
Compactification tolerates vertical displacement but weakens under horizontal shifts. Expansion is fragile to 180° rotation and several translations. The hidden map is interpreted relative to the body’s own geometry.
Pooled across both developmental directions, translations still carry +0.188 and rotations +0.186 donor-directed motion. But both are roughly half the intact +0.369 effect: pose matters even when energy is identical.
A hidden field can encode different transformations with different spatial grammars.
EXPANSION
A phase-coherent, broad spatial relation. Destroy phase or isolate fine structure and the instruction fades.
COMPACTIFICATION
A more redundant, multiscale instruction. It survives full phase scramble and fine-only isolation.
THE RECEIVER
Pose sensitivity shows the map is not read in isolation. Meaning emerges from map × body geometry.
This is no longer just a precursor score. It is a causal syntax: hidden spatial arrangements of equal strength can tell the same visible body to develop differently.
Test whether the language is shared between organisms.
Transplant energy-matched syntax across unrelated bodies. If expansive coarse-phase maps generalize, Flow Lenia has a shared morphogenetic vocabulary. If they only work inside paired lineages, the code is organism-specific memory.
The phase-dose arm should also be repeated as a single coherent interpolation to one fixed scrambled endpoint. That will turn the present distributional dose curve into a clean within-state topology path.
