Experiments

Every sweep of the research programme, with the share of finished runs the transition detector flagged: a compress_ratio collapse that held. A flagged run is not by itself a replicator census — see the findings.

Sweep	Substrate	Status	Runs done	Transition rate	Finding
Asymmetric execution	soup	finished	360 / 360	3%	Does complexity keep rising when only one partner's code runs?
BFF positive control	soup	finished	6 / 6	100%	Does the engine reproduce BFF emergence at all?
Environmental structure	soup	finished	210 / 210	5%	Does complexity keep rising?
From an emerged world	soup	finished	216 / 216	—	Under an energy economy, the dominant replicator copies itself faster From an emerged start, an energy economy does not keep complexity rising
Genes rise	soup	finished	120 / 120	—	—
Host–parasite economy	soup	finished	1800 / 1800	2%	Does complexity keep rising when energy is contested?
Instruction cost	soup	finished	120 / 120	7%	Does complexity keep rising?
Instruction set ablations	soup	finished	60 / 60	7%	—
Lineage diversity	soup	finished	360 / 360	17%	After emergence, one lineage takes the world at every reach
Locality and emergence	soup	finished	630 / 630	15%	Emergence peaks at an intermediate reach
Logic	soup	finished	162 / 162	—	Given a NAND, paid replicators climb every logic task that reads its inputs once, and none that needs one twice
Max steps per interaction	soup	finished	40 / 40	5%	More compute per interaction is not more life
Metabolism	soup	finished	108 / 108	—	Paid to compute, replicators take the one-step tasks and stop there
Meta-stack	soup	finished	162 / 162	—	With a stack NAND on a metabolism tape, paid parts assemble the logic rungs that need an input twice, in a sixth of the worlds
Mutation rate	soup	finished	100 / 100	5%	Life emerged, but the mutation-rate window did not
Mutation rate, long runs	soup	finished	40 / 40	20%	Emergence is rare, and half of it happens after epoch 20 000
Neighbourhood radius	soup	finished	40 / 40	15%	Does spatial locality buy emergence?
Out-compute	soup	finished	216 / 216	—	—
Reach with room to grow	soup	finished	270 / 270	63%	On growable tapes, a reach of 4 emerges more than ten times as often as radius 1
Room to grow	soup	finished	240 / 240	18%	Does complexity keep rising?
Topless rise	soup	finished	162 / 162	—	Paid for depth, the soup jumps once and stands: no late rise on a ladder without a near top
World size	soup	finished	40 / 40	10%	Does time to emergence scale with the number of cells?
