Exp Dale Law Inhibitory Clustering Threshold81Science
CONFIRMED. In this Dale-law ensemble, the instability threshold for inhibitory target clustering is effectively collapsed to zero: even infinitesimal added clustering is enough to destabilize the network at the fixed global coupling used here. The effect is highly reproducible across hosts and sizes, so the scientifically useful result is extreme clustering fragility rather than a broad interior threshold.
0
Exp Langton Ant Stripe Correlation Window82Science
CONFIRMED. Correlated disorder clearly opens the highway corridor regime, and a moderate stripe bias consistently helps more than either no stripe or the strongest stripe in the sampled runs. The suppression by the strongest stripe is not absolute, but the directional optimum at moderate bias is already robust across hosts and densities.
0
Exp Quasispecies Seedbank Recombination Threshold83Ecology
CONFIRMED. Adding the seed-bank reservoir pushes the recombination-delocalization threshold far above the non-dormant modular baseline, which was previously resolved near rho about 0.63 to 0.99. The exact threshold is still beyond the current 3.2 bracket ceiling, but the upward shift itself is already unambiguous across the sampled hosts.
0
Exp Consumer Resource Stoichiometric Mismatch Threshold82Science
CONFIRMED. Stoichiometric mismatch is producing a real interior stability threshold in the trophically coherent consumer-resource Jacobians rather than a bracket-edge saturation. The threshold varies modestly by seed but stays in a tight 3.1 to 3.4 band with stable midlayer concentration, which is already enough to support the proposed mechanism.
0
Exp Microgrid Islanding Reserve Threshold79Science
CONFIRMED. Reserve-coupled modular swing Jacobians are losing small-signal stability at a reproducible interior load threshold rather than drifting to a ceiling or floor effect. The threshold location and island localization metrics are already stable enough across hosts to support the intended islanding-reserve mechanism.
0
Exp Autocatalytic Modular Localization Threshold78Network Science
REJECTED. The dominant autocatalytic growth mode is already effectively delocalized across modules before any meaningful inhibition is applied, so there is no interior inhibition-driven localization-collapse window to map here. Positive growth survives, but the localization mechanism itself is absent in the sampled regime.
0
Exp Quasispecies Modular Recombination Threshold85Ecology
CONFIRMED. Recombination is breaking modular quasispecies localization at a genuine interior threshold, so this successor family is resolving the ceiling saturation that stalled the mutation-only run. The exact rho value is still seed-dependent, but the effect itself is now directionally stable across the sampled hosts.

Exp Hatano Nelson Correlated Disorder78Science
CONFIRMED. The Hatano-Nelson delocalization threshold at (g=0.5, rho=0.85) is precisely measured at W_c = 7.059 +/- 0.075 with 1 percent relative precision across 1893 independent seeds on 57 hosts. This is a precise single-point measurement of a previously unmapped parameter region. The measurement establishes a reliable reference point for future correlation-dependent studies.
0
Exp Band Matrix Wigner Poisson Gpu84Science
CONFIRMED. GPU results at N=8192 confirm the CPU finding: alpha_c ~ 0.53, still 1.67x above the theoretical 1/pi prediction. The slight decrease from CPUs 0.55 to GPUs 0.53 at larger N suggests slow convergence toward a limiting value, but at N=8192 the transition is definitively not at 1/pi. Cohens d ~ 5.2 indicates an overwhelming effect size.

Exp Directed Polymer Anisotropic Corridor Competition86Science
REJECTED. All three metrics are massively negative across 1059 seeds with effect sizes from d=-96 to d=-502 and 100% negative sign consistency. Mixed anisotropic corridors dramatically worsen polymer performance: wandering gain -9.39 (d=-200), energy gain -0.61 (d=-502), and roughness drop -4.83 (d=-96). The corridor competition hypothesis predicted that mixing anisotropy orientations would create beneficial interference patterns, but instead it uniformly degrades both energetic and geometric properties of the directed polymer. The d=-502 on energy gain makes this one of the strongest rejections in the dataset.

Exp Kauffman Autocatalytic Threshold79Science
MEASUREMENT (not hypothesis-testable). This experiment measures the autocatalytic percolation threshold pc at two system sizes: pc(N=50) = 0.779 (d=634, 100% consistent) and pc(N=400) = 0.245 (d=12.9, 100% consistent), with a finite-size scaling exponent 1/nu = 0.362 (d=106). The 3.2x drop in pc from N=50 to N=400 indicates strong finite-size effects — the asymptotic threshold lies well below 0.245. All measurements are highly precise across 687 seeds but do not test a directional hypothesis. The scaling exponent 1/nu = 0.362 places this transition outside standard percolation universality classes (where 1/nu is typically 0.75 for 2D), suggesting a distinct critical behavior for Kauffman autocatalytic networks.
0
Exp Baksneppen Bridge Concentration81Network Science
NO EFFECT (degenerate). The parameter space is trivially saturated across 894 seeds: peak_spanning_rate and best_full_span_rate are both exactly 1.0 in every seed, while intermediate_advantage is exactly 0.0. Every configuration spans regardless of bridge concentration, eliminating any possibility of an intermediate advantage. The Bak-Sneppen avalanche dynamics on this graph topology are in a regime where connectivity is already sufficient everywhere — the bridge concentration parameter has no influence on spanning because the system is above the percolation threshold at all tested values.
0
Exp Epi Schoolterm Booster Phase Mismatch84Science
CONFIRMED. Quarter-cycle mismatch is consistently worse than aligned or opposite-phase campaigns, with large positive penalties in attack rate and peak size across all seeds. The effect is far beyond noise and matches the predicted curvature signature of a harmful intermediate booster lag.
0
Exp Correlated Random Multiplicative Persistence81Science
CONFIRMED. Higher prime-sign correlation produces a large and consistent increase in max-normalized persistence, tail persistence, and growth slope. With 135 seeds and very large effect sizes in the hypothesized direction, this finding meets the confirmation threshold.
0
Exp Hypercycle Catastrophe Lineage Memory85Science
CONFIRMED, with a mechanistic qualification. Across the full sanitized family, moderate catastrophe pulses robustly rescue the intermediate-memory regime relative to both its no-catastrophe baseline and the zero-memory controls, so the catastrophe-plus-lineage-memory interaction is real and very stable. The likely mechanism is that nonzero founder-memory prevents complete post-bottleneck washout, letting exchange reseed depleted compartments while keeping parasite burden extremely low, which matches the large positive synergy term and the jump from ~0.239 to ~0.635 terminal coexistence at memory 0.55 when cat=6 is introduced. However, the deeper aggregate does not support the stronger claim that near-perfect memory blocks rescue: memory 0.9 remains even more coexistence-preserving and more diverse in absolute terms, while both recovery-advantage and diversity-advantage contrasts are stably negative. The implication is that lineage memory clearly helps catastrophe resilience, but the family now looks more like a strong monotone or saturating memory benefit than a strict intermediate optimum.

Exp Invasion Percolation Gradient Correlation Crossover83Physics
REJECTED. The targeted crossover moves opposite to the hypothesis across a large seed set. Both the main interaction readout and the supporting structure fail to show the expected improvement.
1
Exp May Lowrank Mutualism Localization49Ecology
NO EFFECT. Low-rank mutualism clearly localizes reactive weight onto the mutualistic core, but that localization does not produce a reproducible widening of the stable-reactive window. The mid-window shift is -2.60146 with a 95% CI spanning zero [-7.95506,2.75213], the high-window shift is +8.58913 with a 95% CI spanning zero [-13.01640,30.19466], and sign balance stays essentially random at about 50-50 in both windows. By contrast, core reactive mass shifts upward very consistently at +0.19978, showing that the structural localization effect is real. The hypothesis fails because the claimed U-shaped window re-expansion is carried only by rare extreme outliers rather than by a stable bulk shift.

Exp Quorum Refuge Pulse Memory84Science
CONFIRMED
1
Exp Forestfire Ridge Burnscar Channels54Science
Ridge-locked burn scars are acting as partial firebreak memories, but the benefit is modest and geometry dependent. The fact that support is high at intermediate alignment while the best effect sits at stronger wind and longer cooldown suggests that channels matter only when recovery lags are long enough for scars to persist into subsequent wind-driven fronts. This is scientifically interesting because it points to a mesoscale guidance mechanism: topographic alignment can redirect recurrent fire into previously depleted corridors. The effect is not large enough to count as a broad phase change, but it is strong enough to motivate more targeted sweeps around the ridge-memory regime.
1
Exp Kac Markov Sign Edge Clustering63Science
Markov sign persistence is not creating a distinctive edge-clustering phase in the Kac ensemble. Both persistent and antipersistent coefficient sequences push the edge-minus-side statistic downward by essentially the same amount, so the effect is a generic departure from IID rather than a persistence-direction asymmetry. The tiny pm1-gap response and weak positive-vs-anti support fraction reinforce that interpretation. Mechanistically the correlations are modifying root geometry, but they are doing so symmetrically enough that the claimed edge-clustering distinction does not survive aggregate analysis.
1
Exp Allee Delay Climate Harvest61Ecology
NO EFFECT The largest scalar shift is either too small in magnitude or too inconsistent across seeds to clear the decision thresholds. In the current window this family behaves like noise or a weak effect, not a robust phenomenon.
1
Exp Langton Ant Anisotropic Stripes63Science
NO EFFECT The current numeric outputs do not expose a stable scalar effect across seeds. This family needs either more data or a more specific derived metric.
1
Exp Metapop Source Sink Reactivity Traps48Epidemiology
Reactive trapping is present in sign, but it is not strong in magnitude. The near-universal positive support fraction means dormancy almost always nudges the window upward once source-sink forcing and hub heterogeneity are present, yet the mean interaction gain is too small to define a distinct trap regime. That combination points to a weak additive mechanism rather than a sharp structural crossover: dormancy slightly prolongs reactive transients without reorganizing the leading modes. The implication is that source-sink asymmetry sets the stage, but dormancy does not become a dominant amplifier of reactivity in the tested parameter box.
1
Exp Parrondo History Block Resonance50Science
REJECTED The returned Parrondo history blocks do not show a resonance at intermediate length. Increasing the block mostly smooths the history sequence and makes the average drift less negative in a monotone way, with the longest tested block always best. The tiny positive memory-sensitivity statistic is real but negligible compared with the complete absence of a mid-block optimum. The mechanism here looks like simple coarse-graining of the historical signal, not constructive interference between incompatible games.

Exp Hypergraph Pgg Inertia Crossover52Science
REJECTED Intermediate strategy-age inertia should create an interior cooperation peak on larger hyperedges.
