Swap the inside. Keep the body.
For each organism, we kept the recipient’s visible matter field byte-identical, replaced its spatial hidden channel ratio with the aligned donor age, restored the recipient’s global channel balance, then ran the same zero-net causal-order test.
Late hidden state in early body
The q32 body remains responsive. Change from q32 self: +0.010 [-0.025, +0.046].
Early hidden state in late body
The q48 body is not rescued. Change from q48 self: -0.004 [-0.031, +0.023].
Susceptibility is not a portable hidden substance. The recipient body is the decoder.

Median-pattern organism crystal-form-1335, selected mechanically by closeness to all four cohort cell means.
Rows matter. Columns do not.
Crossing visible body age with hidden donor age gives all four possible combinations. Response remains high across the q32-body row and low across the q48-body row.
Body age
The dominant source of direction-specific readability.
Hidden age
No portable main effect of donor hidden age.
Interaction
Heterogeneous coupling, but not the clean population-level carrier.
The decoder turns between q36 and q44.
The dense scan reproduces clear native readability at q32 and q36. q40 is transitional; q44 retains a direction-specific trace; q48 is broadly closed.
This is not an instant clock tick. It is a developmental transition zone in which the body’s interpretation of the same cause is being rewritten.
Information has no fixed meaning outside the body that reads it.
Relational causality
The same Φ-R direction has different causal effects in different bodily organizations.
Embodied commitment
Maturation changes the system’s decoder even when hidden composition is replaced.
Pattern-space bridge
The body is not merely the output of hidden information; it determines what hidden directions can do next.
This is a stronger bridge to causal emergence than a predictive score alone: macro-organization changes the causal vocabulary available to the underlying state.
The next swing is an address matrix: derive developmental control directions at q12, q32, and q48, then apply each direction to each body age. Does the vocabulary rotate during development—or does causal plasticity truly close?
