Exp Ballistic Annihilation Domain Correlations82Science
Long same-sign domains robustly create a survivor window in ballistic annihilation. The effect survives across the full occupancy range, so it is not a single-density artifact, and the optimum remains pinned to the strongest tested correlation scale. The front-drop reduction shows the mechanism directly: correlated initials remove many immediate opposite-velocity interfaces, delaying early annihilation bursts and preserving a much larger survivor population. Because the gain is both large and narrow in parameter space, the experiment points to interface density, not bulk occupancy, as the dominant control variable for late-time survival.

Exp Markov Branching Rescue Correlation88Science
CONFIRMED Rescue immigration coupled to good phases preserves a strong interior-persistence structure, while bad-phase rescue almost completely flattens it. The key mechanism is not just higher raw survival: anti-correlated rescue keeps populations alive in bad epochs and therefore erases the persistence-sensitive contrast between good and bad stretches. Good-correlated rescue does the opposite, reinforcing long favorable runs and producing a pronounced phase-survival asymmetry that peaks at intermediate persistence. The result shows that rescue timing relative to environmental state is a first-order control parameter for near-critical branching, not a small perturbation.

Exp Forestfire Patchy Moisture Memory71Science
CONFIRMED. Patchy moisture memory produces a consistent and significant improvement in fire suppression, with the best spanning gain at +0.025 (d=10.92, 100% sign consistency across 280 results on 19 hosts). Spatial memory of previous moisture patterns creates natural firebreaks that persist across burning cycles.

Exp Quasispecies Seedbank Reactivation Leak Threshold Gpu Gpu78Ecology
CONFIRMED. In the live GPU runs, the seed-bank localization advantage is not destroyed immediately by infinitesimal reactivation leak; it survives up to a reproducible nonzero leak threshold near 1.1. That is the core hypothesis of this successor family, and the sampled hosts already show the threshold as an interior effect rather than a zero-leak collapse or a ceiling-saturated bound.

Exp Nasch Incident Cluster Anticipation90Science
Anticipation reliably improves throughput in incident-rich traffic, and the best summaries overwhelmingly favor the densest tested road together with the highest anticipation fraction. In the reconstructed condition grid, moving from 35% to 70% anticipatory drivers roughly doubles the flow gain while sharply reducing jam fractions. The advantage remains positive from unclustered to strongly clustered incidents, so the effect is not confined to one persistence regime. The likely mechanism is earlier braking and gap management near incident zones, which damps stop-and-go wave growth before localized disruptions spread into network-scale jams.

Exp Metapop Seedbank Corridor Correlation88Epidemiology
The seed bank is acting as a true catastrophe-memory buffer rather than just adding a small demographic cushion. When disturbances are spatially broad, dispersal alone cannot outrun simultaneous losses, and the no-bank system nearly always collapses; dormant storage reverses that regime completely. The strongest rescue appears when immediate movement is allowed, implying that corridor flow and temporal storage are complementary rather than substitutable. The effect weakens but remains large at higher thresholds, which is consistent with delayed dispersal sacrificing recolonization speed after correlated shocks.

Exp Hypergraph Pgg Fixation77Population Genetics
CONFIRMED. Frequency-dependent public-goods benefits partially reverse the known suppressor-of-selection behavior of random hypergraphs, but only once the multiplication factor clears a hyperedge-size-dependent threshold near r approximately 2.6 to 2.8. Small hyperedges amplify a single cooperator most strongly because local contributions are less diluted, so the payoff advantage survives weak-selection averaging and produces fixation rates roughly double neutral at k=2, r=8. As hyperedges grow, the same contribution is spread across more neighbors, which pushes the system back toward neutral or mildly suppressive behavior and explains why the critical threshold rises slightly with k while the attainable max fixation ratio falls. The right-skewed condition-level distributions indicate occasional very strong amplification realizations rather than a narrow deterministic shift, which fits a mechanism where random hypergraph membership sometimes creates unusually favorable cooperative exposure patterns. Scientifically, this means hypergraph structure alone does not universally suppress selection once payoffs are endogenous: game-induced synergy can overcome structural suppression, but the required synergy grows with interaction group size.

Exp Branching Overdispersion Environment Resonance75Science
CONFIRMED. The interior resonance is not a fragile single-parameter artifact: every amplitude-dispersion block retains a finite-memory peak in extinction-time heterogeneity, with the ensemble peak locked near p_stay approximately 0.66. Raising environmental amplitude shifts the preferred persistence lower, from about 0.70 at amplitude 0.14 to about 0.61 at amplitude 0.28, which is consistent with stronger environmental swings requiring less temporal memory to maximize lineage-to-lineage timing spread. Moderate offspring overdispersion is the strongest amplifier, with k=1 producing the largest interior-peak excess at both amplitudes, while heavier overdispersion gradually damps but does not erase the effect. The mechanism is a burstiness-memory coupling: negative-binomial offspring variability broadens extinction-time distributions most when environmental runs are long enough to create coherent good and bad stretches, but not so long that trajectories collapse into near-deterministic fast-die or long-survive regimes.

Exp Littlewood Block Realroot Crossover84Science
REJECTED. The data reject a monotone claim that stronger block persistence pushes Littlewood real roots toward the edges at x=+/-1. What the experiment robustly shows instead is a crossover in root-count suppression: once block length reaches about 1.27*sqrt(degree), the expected number of real roots is cut roughly in half. Edge localization is nonmonotone, with moderate persistence lengths (blocks 4 to 8) increasing near-edge mass slightly, but the longest blocks lowering edge mass below the iid baseline. The likely mechanism is that short-range sign persistence removes some high-frequency cancellations and temporarily favors edge-adjacent roots, whereas long constant-sign stretches suppress sign changes so strongly that they eliminate real roots faster than they concentrate the survivors near the endpoints.

Exp Minority Game Delay Memory Interaction72Science
REJECTED. Shared delay amplifies volatility in the bimodal-memory population instead of creating the predicted intermediate-delay minimum. The aggregate mid-delay volatility gain is -0.47529 with a 95% CI of [-0.48150,-0.46907], and 99.4% of sanitized runs have the wrong sign. Bimodal memory also remains substantially noisier than the best uniform-memory control, with a mid-delay gap of -2.18882, while its per-condition volatility rises from 2.42585 at delay 0 to 3.50661 at delay 16. The data therefore indicate that delayed common information drives larger synchronized overshoots rather than stabilizing crowd behavior.

Exp Directed Polymer Kpz Exponent72Science
REJECTED. The measured wandering exponent (0.704) is more than double the exact KPZ prediction (1/3 = 0.333), stable across 1206 seeds with d=17.2 and 100% sign consistency. The tight cross-distribution spread (0.017) rules out noise — the estimate is consistently wrong, not noisy. This systematic upward bias points to finite-size contamination: at the system lengths reached by the iterative deepening budget, the polymer hasn’t entered the asymptotic KPZ scaling regime where chi converges to 1/3. A much larger system (or longer polymer) would be needed to see the crossover, making this a problem where the current compute budget is genuinely insufficient rather than a hypothesis failure.

Exp Logistic Benford Deviation74Statistics
CONFIRMED. Deviations from Benford's law in logistic map iterates are strongly correlated with the Lyapunov exponent (r=-0.83, d=5.47) and the periodic-to-chaotic orbit ratio is highly reproducible across 776 seeds (d=136.83, 100% sign consistency). This establishes a quantitative link between digit-distribution anomalies and dynamical regime, confirming that Benford violations serve as a reliable proxy for the onset of chaos in discrete maps.

Exp Nasch Incident Memory Heterogeneity82Science
Memory heterogeneity is a genuinely large traffic-control effect in this incident setting. The striking result is that the best gain does not require anticipatory drivers; even with anticipation fixed at zero, a finite memory window sharply improves throughput and suppresses jams. That points to history-dependent local adaptation, not lookahead, as the dominant mechanism: drivers with heterogeneous memory smooth recurrent incident bottlenecks by retaining useful responses across events. Because the effect survives across incident durations with minimal variance, it looks like a robust operational lever rather than a brittle corner case.

Exp Trophic Pulse Layer Filtering76Ecology
The food-web response is genuinely layer selective. Mid-layer pulsing behaves like a band-pass filter: it preserves or enlarges response area while also improving retention, whereas top-layer forcing over-attenuates the signal and collapses area. The strong noise dependence suggests that intermediate coherence is needed for the middle trophic layer to redistribute pulses without simply dissipating them. The implication is that trophic position, not just pulse magnitude, determines whether perturbations are filtered, amplified, or lost as they propagate through the stack.

Exp Kuramoto Partial Overlap Anticorrelation79Science
Anticorrelated shared frequencies strongly frustrate interlayer locking on the overlap set. The clearest signal is not a simple drop in bulk coherence, but a collapse in the fraction of shared oscillators that remain phase-locked together with a large increase in interlayer phase separation. Positive correlation restores locking at the same overlap and coupling, which ties the effect to the sign structure of the shared frequencies rather than overlap alone. Mechanistically, the shared nodes behave like persistent sources of phase mismatch that propagate frustration across both layers.

Exp Spacing Ratio Crossover83Science
This is a clean finite-size scaling result. The low CV of lambda_c*sqrt(N) shows that the crossover is governed by the expected sqrt(N) rescaling rather than by unrelated matrix-size effects. The condition table indicates that once the rescaled control variable is large enough, spacing statistics collapse rapidly onto the GOE plateau across sizes. The implication is that the crossover is controlled by a single emergent scaling combination, making it a robust benchmark for universality tests in related spectral ensembles.

Exp Standard Map Anticorrelated Kicks72Science
Anticorrelated kicks do suppress transport in the narrow pair, but they do so by quenching the dynamics rather than by making them more intermittent. The negative intermittency-excess statistic means antipersistence reduces FTLE-window variability even while it increases quiet episodes, so the original burstiness narrative is backwards. The broad pair comparison also undermines the claimed narrow-pair specificity, since the transport penalty does not become uniquely stronger there. The implication is a weak anti-transport effect tied to temporal smoothing, not a distinctive intermittency-driven crossover.
1
Exp Parrondo History Boundary80Science
The history-dependent Parrondo boundary is a stable codimension-one object in parameter space, not a noisy mosaic. The small variability in crossing count means the alternating-game winning region has a reproducible topology even when the precise drift values fluctuate. That matters because it supports a genuine boundary interpretation: sign changes in mean drift occur along a narrow structured curve rather than being scattered by sampling noise. The implication is that history dependence creates a robust winning wedge that can be tracked and potentially optimized by boundary-following methods.

Exp May Heterogeneity Reactivity Localization86Ecology
CONFIRMED. Species-level interaction heterogeneity simultaneously widens the stable-but-reactive window (from 0.35 to 4.31) and localizes reactive modes onto a shrinking subset of species (IPR rises from 0.05 to 0.34), with correlation r=0.82 between the two effects. This bridges May's stability theory with Anderson-style localization: stronger heterogeneity creates communities that are linearly stable yet highly vulnerable to amplified transients through a few concentrated state-space directions.

Exp Hypercycle Compartment Pulse Inheritance68Science
CONFIRMED. The data support a real lineage-level synergy between migration pulses and inheritance, even though bulk occupancy does not improve. The best synergy gain is +0.02602 with a tight 95% CI of [0.02512,0.02692] and 100.0% positive sign consistency, whereas the best occupancy gain stays slightly negative at -0.00304. Baseline controls have exactly zero synergy, and pulse-only conditions raise rescue rates into the 0.19090-0.25578 range while still incurring occupancy losses. This points to a selective reseeding-and-memory mechanism that preserves favorable catalyst composition across bottlenecks rather than increasing overall compartment filling.
