The gate stays open.
One strong early intervention—followed mostly by restraint—held Flow Lenia’s causal-developmental degrees of freedom open for eight passages after release.
Hit early. Then get out of the way.
At every passage, the controller tried five spatial pulse sizes and asked which future preserved the greatest separation between alternative causal histories. It was free to keep forcing. It usually chose not to.
Mean chosen dose by passage
The asymmetric recipe
Open: 25 of 39 organisms chose the full pulse at passage 1. Then 28, 32, and 28 chose zero at passages 2–4.
Close: only one chose full strength at passage 1. Later, heavy doses dominated.
The controlled difference survived after control ended.
Passage 4 is the score the controller directly optimized. Passages 6, 8, and 12 were untouched futures. The open and closed worlds remained apart throughout.
Open minus closed: causal-history separation
Eight passages later
95% interval [0.013, 0.023]. The direction was positive in 34 of 39 organisms.
The cumulative post-release difference across passages 6, 8, and 12 was +0.075, interval [0.059, 0.090].
Blindly hammering the system did the opposite.
The full-strength pulse applied at every passage did not hold the gate open. It pushed causal-history separation below the untouched world. The adaptive controller beat blind full forcing at every measured age—including eight passages after release.
The causal worlds diverged while coarse field displacement stayed almost identical.
Open and closed branches were both far from the untouched state. But their distance from untouched was nearly the same—the mean open-minus-closed field-distance contrast stayed near zero.
This is not simply “one controller moved more pixels.” The intervention changed what the state could still become under alternative histories.
Open minus closed field displacement
P4: -0.000 while causal separation was +0.037
P6: +0.013 while causal separation was +0.029
P8: +0.012 while causal separation was +0.027
P12: +0.000 while causal separation was +0.018
Developmental commitment is now something we can control.
In plain words: early Flow Lenia development contains a controllable gate. A correctly timed pulse can place the same material into a state that remains more responsive to its later causal history. Repeated brute-force correction closes that gate instead.
This was not one lucky creature.
Use the open gate to rewrite what organism forms.
Freeze each organism’s discovered pulse sequence, perturb its trajectory slightly, then compare blind replay with fresh feedback. This tells us whether the controller learned a transferable recipe or genuinely tracks a moving developmental state.
First place the system in the open or closed regime. Then deliver the same second intervention to both. If the open regime produces a broader or different future repertoire, we have direct control over developmental possibility—not merely a metric.
Visible transition timing did not yet separate cleanly: open minus closed advance +4.3 steps, interval [-8.8, 18.1]. That is the next frontier, not a reason to shrink the present finding.
