high-commitment descendants scored above their low-commitment siblings before any long future existed.
01 · The causal question
Can one state be pushed toward commitment?
Each organism starts from one q32 ancestor. Eight equal first actions create eight descendants. At q36, before the visible transition, the portable commitment coordinate selects the most- and least-committed descendant. Only then do both receive the same continuation plus eight second actions.
02 · The manipulation
The sibling states really separated.
The high branch exceeded the low branch in all 30 ancestors. The mean coordinate gap was 0.563 portable percentile units; the smallest was 0.270.
Both high and low selections used varied first-action identities across ancestors. The effect is not one fixed lucky action.
03 · The result
The microscopic causal repertoire contracted.
Under the same eight later actions, the high-commitment descendant produced a mean pairwise final-field repertoire 0.0078 Hellinger units narrower than its low-commitment sibling. The paired 95% interval is [-0.0152, -0.0008].
individual ancestors narrowed; the mean remains negative after leaving out every ancestor.
organic organism groups point in the contraction direction.
A local action did not merely change a score. It changed the set of later outcomes that other actions could reach.
04 · Across scales
Microscopic contraction is clear. Timing begins to follow.
The high branch also had a transition-time repertoire 2.57 steps narrower on average. But that interval [-6.67, +1.00] still reaches zero. The current action reliably moved microscopic causal breadth; macroscopic event timing is a directional lead.
Commitment may begin below the visible event: first the response repertoire contracts, then the macroscopic transition becomes canalized.
05 · Breadth
Seven of eight organism groups contract.
The effect is not uniform—living-like systems rarely are—but it is distributed across the cohort rather than confined to one morphology family.
06 · The actual descendants
Same ancestor. Different causal reach.
The strongest contraction and the strongest timing reversal show both the power and the remaining heterogeneity of the intervention.
strongest timing contraction
crystal-pattern-1464
Coordinate gap 0.486. Timing repertoire: low 78 steps → high 40.
strongest timing reversal
radiant-blob-1636
Coordinate gap 0.545. Timing repertoire: low 19 steps → high 35.
07 · The next swing
Turn a nudge into a regime change.
Does a longer or repeated commitment-directed pulse amplify the microscopic contraction into robust macroscopic timing control, and does release reveal hysteresis?
Compare one, two, and four commitment-directed pulses. Ask whether repertoire contraction scales with dose and duration.
Stop driving, replay the same action sequence open-loop, and measure whether the state remembers having crossed the commitment boundary.
We can now forecast causal commitment and perturb the later possibility space. The next question is whether repeated information-directed action can lock in a new developmental regime.
