Does the first regime change how the second is decoded?
Each body received a prime, sixteen unforced steps, then a test. Prime and test could be absent, 0.5×, or 4×. The full matrix lets us subtract prime alone, test alone, and the untreated future.
none · 0.5× · 4×
no intervention
none · 0.5× · 4×
The nonlinear residue is what neither dose can do alone. Then we compare 0.5→4 against 4→0.5. Both paths carry exactly the same total absolute dose.
One path reaches inward. The other stays near the surface.
The 0.5→4 path creates a direction-specific dense-core synergy of +1.818. The reverse path creates -0.011. At the surface, their ordering flips.
Surface memory
Reversing the dose order reverses the surface-weighted part of the response.
Dense-core memory
Seven of eight family groups carry the inward shift.
Depth separation
The strongest summary: equal total dose, different causal depth.
The body does not merely remember that it was perturbed. It remembers which response regime came first, and expresses the next perturbation at a different physical depth.
Connectivity remembers specifically. Size mostly remembers timing.
Radius also differs between the two paths: native order gives -0.077, but the orthogonal control gives almost the same -0.074. Their direction-specific difference is only -0.003 [-0.067, +0.057].
Information-specific memory
Surface and dense-core connectivity carry the privileged-direction order interaction.
Generic temporal memory
Both native and orthogonal perturbations remember amplitude order similarly.

A fixed illustration from source 01, native cancel-first, release +32. Cream is the largest connected body, cyan a detached component carrying at least 0.25% of field mass, orange a smaller fragment. The statistical result uses all 31 organisms, both causal orders, and the orthogonal direction control.
That distinction matters. The information direction is not just a stronger shove. Its specific history is written into the body’s stratified connectivity.
Ending at the surface opens a daughter-state window.
For immediate entry into a ≥5%-mass secondary-body state, 0.5→4 minus 4→0.5 is -22.9 percentage points [-40.6, -4.2]. In plain words: the path ending in the low topological dose is more likely to enter the daughter-like state than the path ending in the high expansion dose, after removing both single-dose effects.
The same order that leaves the response near the surface also makes transient macroscopic separation more accessible. That is our first direct bridge from information history → density topology → daughter-state entry.
How long does the body remember?
Gap duration
Repeat the equal-dose cross at 0, 16, 32, 64, and 128 unforced steps. Map the decay—or consolidation—of the depth trace.
Read the hidden state
Measure density-shell connectivity immediately before the second pulse and ask which state variable predicts how deep the response will go.
Follow daughters
Track whether surface-biased memory precedes stable mass separation, independent motion, or reintegration.
The bold possibility is no longer abstract: a Flow Lenia organism may carry a short developmental memory in its physical stratification, and that memory may choose whether the next information-geometric event becomes surface remodeling, core reorganization, or fission.
