Batch cycle-001. Model 0.1.0, graph 0.2.0, parameters 0.1.0. 100 simulations, seeds 1 to 100; probes on 20. Every figure is a distribution over simulations of a structural model with seed parameter values; it shows what the model implies under these settings, not what will happen. Other nations are frozen at their 2026 ratings. No reconstructed historical data is used in this experiment.
Headline
Kenya played 20 rounds from 2026 under the greedy marginal method, with stochastic events, 100 times. Its capability index moved from 7.18 to a median of 7.38 (+0.20), with 90 per cent of simulations between 5.45 and 8.19 [experiment_objectives].
Starting position
In 2026 the nation ranks 79 on the index against the frozen field, holds 0 of nine domains at Tier 1 and has a tier rank of 91. Its base income is 143 credits a year, calibrated so that its 2026 position is affordable with headroom for investment.
What was decided
A simulation spent a median of 539 credits on moves. The five groups that took most were Semiconductors & Advanced Computing (buy, 64 credits, 11.6 per cent); Connectivity, Cyber & Trust Technologies (buy, 46 credits, 8.4 per cent); Technical & Vocational Skills (build, 41 credits, 7.5 per cent); Development Cooperation & Global Assistance (buy, 33 credits, 6.2 per cent); Artificial Intelligence (buy, 31 credits, 5.8 per cent) [experiment_decisions_by_group]. By mode: buy 55 per cent, partner 30 per cent, build 15 per cent [experiment_decisions_by_group]. Concentration of spending (HHI) had a median of 0.063, and the most repeated action appeared in 50 per cent of rounds.
The leading domain by period: rounds 1 to 5, Human Capital; rounds 6 to 10, Critical Technology; rounds 11 to 15, Critical Technology; rounds 16 to 20, Critical Technology [experiment_spend_by_period].
The method's chosen action was within 5 per cent of its best alternative in 94 per cent of moves and ahead by more than 25 per cent in 0 per cent [experiment_decision_margins].
What the world did
A median simulation saw 2 shocks and 0 upside events. The most damaging per firing were S06 (32 firings in 28 simulations, −59.1 points each); S03 (33 firings in 31 simulations, −48.2 points each); S05 (9 firings in 9 simulations, −38.6 points each) [experiment_shocks]. Upside events fired 51 times across all simulations [experiment_shocks].
The groups that lost most to shocks, per simulation: Fiscal Capacity & Public Finance −2.10; Trade Facilitation & Logistics −1.86; Monetary & Currency Capability −1.65; Economic Leverage & Dependence −1.60 [experiment_shock_damage_by_group].
The edges that carried most change through the graph, per simulation: Semiconductors & Advanced Computing to Artificial Intelligence (+1.38 points); Semiconductors & Advanced Computing to Economic Leverage & Dependence (+0.50 points); Connectivity, Cyber & Trust Technologies to Cyber & Electromagnetic Operations (+0.47 points) [experiment_propagation_by_edge].
Where it ended
At 2046 the median rank is 76 (5th to 95th percentile 65 to 111), the median count of Tier 1 domains 0 (0 to 0) and the median tier rank 72; the resilient score, the mean score sum over simulations, is 503 [experiment_objectives].
Why
Without shocks the index ends +1.361 higher on average, so the shocks cost about 1.361 index points [experiment_probe_attribution].
Holding instead of following this method changes the index by −0.994: that is the method's worth against doing nothing [experiment_probe_attribution].
Removing any single one of the five largest actions changes the index by between −0.015 and −0.011, for example 2039 partner Fiscal Capacity & Public Finance (8 credits) [experiment_probe_attribution]. The largest actions by credits come late, when income is highest, and are rarely the most valuable.
Removing the largest shock of a simulation raises the index by +0.767 on average [experiment_probe_attribution].
The replay probe reproduces the simulations exactly (index change 0.000000), so the attributions are clean [experiment_probe_attribution].
Surprises
tier_jump (warn): largest gain in one domain within five years: 4 tiers (96 simulations above 2).
retired_words (warn): e3-ken-greedy-marginal/report.md: 'simulations' 1 time(s), first near line 39; use 'simulations'.
The simulation furthest from the median (seed 33) ends −4.31 from it, with 7 shocks and 0 upside events [experiment_outlier_simulations].
Comparison
Against the hold experiment for the same nation (e3-ken-hold), the median index is +0.98 points apart, the median rank 76 against 91, and Tier 1 domains 0 against 0 [experiment_against_hold].
No backcast comparison: this experiment does not start from a historical position [experiment_against_history].
