Batch cycle-002. Model 0.1.0, graph 0.2.0, parameters 0.1.0. 30 simulations, seeds 1 to 30; probes on 10. 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
Hungary played 30 rounds from 1996 under the scripted method, with scripted events, 30 times. Its capability index moved from 10.85 to a median of 11.04 (+0.19), with 90 per cent of simulations between 11.03 and 11.06 [experiment_objectives].
Starting position
In 1996 the nation ranks 36 on the index against the frozen field, holds 0 of nine domains at Tier 1 and has a tier rank of 39. Its base income is 312 credits a year, calibrated so that its 2026 position is affordable with headroom for investment.
What was decided
A simulation spent a median of 1,612 credits on moves. The five groups that took most were Trade Policy & Market Access (partner, 158 credits, 9.8 per cent); Fiscal Capacity & Public Finance (partner, 131 credits, 8.1 per cent); Transport Infrastructure (partner, 131 credits, 8.1 per cent); Government Effectiveness & Public Administration (partner, 131 credits, 8.1 per cent); Alliances & Security Cooperation (partner, 131 credits, 8.1 per cent) [experiment_decisions_by_group]. By mode: build 51 per cent, partner 49 per cent [experiment_decisions_by_group]. Concentration of spending (HHI) had a median of 0.087, and the most repeated action appeared in 43 per cent of rounds.
The leading domain by period: rounds 1 to 5, Trade & Investment; rounds 6 to 10, Strategic Infrastructure; rounds 11 to 15, Strategic Infrastructure; rounds 16 to 20, Financial Strength; rounds 21 to 25, Human Capital; rounds 26 to 30, Human Capital [experiment_spend_by_period].
What the world did
A median simulation saw 3 shocks and 1 upside events. The most damaging per firing were S10 (30 firings in 30 simulations, −36.5 points each); S02 (30 firings in 30 simulations, −26.2 points each); S01 (30 firings in 30 simulations, −26.2 points each) [experiment_shocks]. Upside events fired 30 times across all simulations [experiment_shocks].
The groups that lost most to shocks, per simulation: Fiscal Capacity & Public Finance −2.65; Labour & Employment −2.50; Monetary & Currency Capability −2.43; Investment Attraction & Projection −2.27 [experiment_shock_damage_by_group].
The edges that carried most change through the graph, per simulation: Fiscal Capacity & Public Finance to Social Infrastructure (+0.91 points); Fiscal Capacity & Public Finance to Force Generation & Mobilisation (+0.65 points); Transport Infrastructure to Trade Facilitation & Logistics (+0.91 points) [experiment_propagation_by_edge].
Where it ended
At 2026 the median rank is 36 (5th to 95th percentile 36 to 36), the median count of Tier 1 domains 3 (3 to 3) and the median tier rank 5; the resilient score, the mean score sum over simulations, is 797 [experiment_objectives].
Tier 1 probability changed most in: governance and integrity (0 to 100 per cent of simulations); strategic infrastructure (0 to 100 per cent of simulations); trade and investment (0 to 100 per cent of simulations) [experiment_tiers_by_round].
Why
Without shocks the index ends +1.426 higher on average, so the shocks cost about 1.426 index points [experiment_probe_attribution].
Holding instead of following this method changes the index by −1.298: 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 −0.020 and −0.004, for example 2021 build Population Health (19 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 +0.587 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: 6 tiers (30 simulations above 2).
saturation_low (warn): 100% of simulations end with a group at 0 that did not start there (median 1 groups).
retired_words (warn): e4-hun/report.md: 'simulations' 2 time(s), first near line 39; use 'simulations'.
The simulation furthest from the median (seed 18) ends −0.03 from it, with 3 shocks and 1 upside events [experiment_outlier_simulations].
Comparison
This is the baseline (hold) experiment, or there is none for this nation in the batch.
Against history: from a reconstructed index of 10.85 the model ends at 11.05, where the 2026 ratings put it at 10.51. Group scores miss by 1.76 points on average, against 0.92 for assuming nothing changed (skill −0.90); the change in each domain has the right sign in 33 per cent of domains. Furthest below history: financial strength (−1.03); furthest above: governance and integrity (+2.02) [experiment_against_history]. The starting position is reconstructed, so part of the error is the reconstruction's.
