The capability index is the mean of the three dimensions, each the mean of its domains, each the mean of its groups. Tiers are Pareto layers within each domain; the tier rank orders nations by domains held at Tier 1, then Tier 2, and so on. The goal-weighted score is the score sum unless the experiment sets a goal. The primary objective is the one the experiment is judged on; every other objective is reported beside it.

Against history

Started from a reconstructed 1996 position and played along the pathway and shocks South Korea actually had, then scored against the 2026 ratings. The position is an estimate, so part of any error is the reconstruction's. The calibration summary across all fifty nations is on the cycle's page under Loop.

The history it was played under: shocks and events

  • 1997 · S02 × 1 The won collapsed, banks and chaebols faced insolvency, and South Korea required a US$58 billion IMF-led rescue package.
  • 2008 · S02 × 0.6 The global financial crisis hit Korean banks' external rollovers and exports, but reserves and swap lines cushioned the shock.
  • 2019 · S01 × 0.4 Japan's export controls on semiconductor and display materials struck at critical supply chains.
  • 2020 · S10 × 0.7 COVID-19 caused a public health emergency and export contraction, though K-quarantine limited domestic spread.

Reconstruction notes (deepseek-v4-pro): The 1996 baseline for rapidly changing technology groups is approximate because South Korea stood between developmental-state capacity and the frontier in many domains. Military and security scores are especially uncertain because public data are incomplete and dependent on US alliance capabilities. Financial sector scores reflect known vulnerability before the 1997 crisis.

Report

Written from the simulation record by the loop's narrator. Every figure names the query it came from, in square brackets.

Batch cycle-003. Model 0.2.0, graph 0.2.0, parameters 0.1.1. 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

South Korea played 30 rounds from 1996 under the scripted method, with scripted events, 30 times. Its capability index moved from 13.13 to a median of 12.72 (−0.40), with 90 per cent of simulations between 12.71 and 12.73 [experiment_objectives].

Starting position

In 1996 the nation ranks 21 on the index against the frozen field, holds 0 of nine domains at Tier 1 and has a tier rank of 22. Its base income is 649 credits a year, calibrated so that its 2026 position is affordable with headroom for investment.

What was decided

A simulation spent a median of 1,569 credits on moves. The five groups that took most were Semiconductors & Advanced Computing (build, 284 credits, 18.1 per cent); Connectivity, Cyber & Trust Technologies (build, 155 credits, 9.9 per cent); Trade Policy & Market Access (build, 127 credits, 8.1 per cent); Government Effectiveness & Public Administration (build, 127 credits, 8.1 per cent); Financial Stability & Crisis Management (build, 127 credits, 8.1 per cent) [experiment_decisions_by_group]. By mode: build 100 per cent [experiment_decisions_by_group]. Concentration of spending (HHI) had a median of 0.096, and the most repeated action appeared in 37 per cent of rounds.

The leading domain by period: rounds 1 to 5, Financial Strength; rounds 6 to 10, Critical Technology; rounds 21 to 25, Critical Technology; rounds 26 to 30, Critical Technology [experiment_spend_by_period].

What the world did

A median simulation saw 4 shocks and 0 upside events. The most damaging per firing were S10 (30 firings in 30 simulations, −25.3 points each); S02 (60 firings in 30 simulations, −14.9 points each); S01 (30 firings in 30 simulations, −14.3 points each) [experiment_shocks].

The groups that lost most to shocks, per simulation: Fiscal Capacity & Public Finance −2.25; Investment Attraction & Projection −2.21; Labour & Employment −2.19; Monetary & Currency Capability −2.11 [experiment_shock_damage_by_group].

The edges that carried most change through the graph, per simulation: Connectivity, Cyber & Trust Technologies to Cyber & Electromagnetic Operations (+0.50 points); Financial Regulation & Integrity to Financial Infrastructure (+0.38 points); Fiscal Capacity & Public Finance to Social Infrastructure (−0.42 points) [experiment_propagation_by_edge].

Where it ended

At 2026 the median rank is 23 (5th to 95th percentile 23 to 23), the median count of Tier 1 domains 2 (2 to 2) and the median tier rank 8; the resilient score, the mean score sum over simulations, is 930 [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) [experiment_tiers_by_round].

Why

Without shocks the index ends +1.060 higher on average, so the shocks cost about 1.060 index points [experiment_probe_attribution].

Holding instead of following this method changes the index by −0.840: 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 −0.036 and +0.017, for example 1997 build Financial Stability & Crisis Management (32 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 +0.370 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); tiers are reported, not an objective.

retired_words (warn): e4-kor/report.md: 'simulations' 1 time(s), first near line 39; use 'simulations'.

The simulation furthest from the median (seed 14) ends −0.02 from it, with 4 shocks and 0 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 13.13 the model ends at 12.72, where the 2026 ratings put it at 16.00. Group scores miss by 3.52 points on average, against 2.86 for assuming nothing changed (skill −0.23); the change in each domain has the right sign in 11 per cent of domains. Furthest below history: information and influence (−4.06); furthest above: strategic infrastructure (−2.58) [experiment_against_history]. The starting position is reconstructed, so part of the error is the reconstruction's.

What each decision and shock was worth

Counterfactual probes on the first 10 seeds: the same simulations with one thing changed, paired seed by seed. A removed decision or shock is taken out and the other decisions replayed unchanged, so the difference is that item's worth.

Not a forecast
Every figure is a distribution over the simulations of a structural model, reported to compare methods and test the model. None is a prediction of what a nation will do or become.
Structural parameters
Costs, decay, vulnerability and credits are structural seed values with low or medium confidence, set by domain with single-group exceptions. Five groups have no defensible value in a single-nation model and are flagged in the parameter tables.
Other nations are frozen
One nation is simulated at a time. Every other nation stays at its 2026 rating, so rank and tiers are measured against a still field; where the simulated nation rises past others their own tiers are not re-sorted.
Starting depth and mode are defaults
The position is the National Capability Index ratings. How institutionalised each capability is, and how much was built, bought or partnered, have no data behind them yet and start from structural defaults.
Credits are calibrated, not measured
Each nation’s income is set so that its position is affordable with headroom that rises with its fiscal capacity. It is not yet fiscal capacity as a share of GDP.
