Capability index by round

Rank by index, by round

Every objective at the position and at the horizon
Objective	2026	10th percentile	Median	90th percentile	Better
Capability indexprimary	11.69	11.11	12.04	12.57	higher
Rank by index	30	25	29	35	lower
Tier rank	33	22	31	34	lower

Goal-weighted score	843.9	806.6	870.6	907.8	higher
Resilient score	843.9	864.5 (mean score sum over the simulations)			higher

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.

Credits

What each round’s credits went on in the median simulation. Across all simulations, build took 36 per cent, buy took 27 per cent, partner took 37 per cent of the 1,021 credits a simulation spent on actions.

Report

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

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

Brazil played 20 rounds from 2026 under the random method, with stochastic events, 100 times. Its capability index moved from 11.69 to a median of 12.04 (+0.35), with 90 per cent of simulations between 10.93 and 12.61 [experiment_objectives].

Starting position

In 2026 the nation ranks 30 on the index against the frozen field, holds 0 of nine domains at Tier 1 and has a tier rank of 33. Its base income is 386 credits a year, calibrated so that its 2026 position is affordable with headroom for investment.

What was decided

A simulation spent a median of 1,023 credits on moves. The five groups that took most were Labour & Employment (build, 16 credits, 0.6 per cent); Joint Command, Projection & Sustainment (build, 16 credits, 0.7 per cent); Space Operations (partner, 16 credits, 0.6 per cent); Sovereign Capital & External Financial Power (build, 16 credits, 0.6 per cent); Energy Infrastructure (partner, 16 credits, 0.5 per cent) [experiment_decisions_by_group]. By mode: build 36 per cent, partner 36 per cent, buy 27 per cent [experiment_decisions_by_group]. Concentration of spending (HHI) had a median of 0.027, and the most repeated action appeared in 15 per cent of rounds.

The leading domain by period: rounds 1 to 5, National Security; rounds 6 to 10, Strategic Infrastructure; rounds 11 to 15, Critical Technology; rounds 16 to 20, Critical Technology [experiment_spend_by_period].

What the world did

A median simulation saw 2 shocks and 1 upside events. The most damaging per firing were S09 (9 firings in 9 simulations, −32.8 points each); S10 (3 firings in 3 simulations, −30.7 points each); S08 (33 firings in 29 simulations, −29.0 points each) [experiment_shocks]. Upside events fired 92 times across all simulations [experiment_shocks].

The groups that lost most to shocks, per simulation: Fiscal Capacity & Public Finance −1.10; Information Environment & Strategic Communication −0.97; Digital & Services Trade −0.93; Trade Facilitation & Logistics −0.90 [experiment_shock_damage_by_group].

The edges that carried most change through the graph, per simulation: Semiconductors & Advanced Computing to Artificial Intelligence (+0.06 points); Economic Output & Productivity to Fiscal Capacity & Public Finance (+0.03 points); Fiscal Capacity & Public Finance to Social Infrastructure (−0.09 points) [experiment_propagation_by_edge].

Where it ended

At 2046 the median rank is 29 (5th to 95th percentile 25 to 35), the median count of Tier 1 domains 0 (0 to 0) and the median tier rank 31; the resilient score, the mean score sum over simulations, is 864 [experiment_objectives].

Why

Without shocks the index ends +0.847 higher on average, so the shocks cost about 0.847 index points [experiment_probe_attribution].

Holding instead of following this method changes the index by −0.778: 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 −0.017 and −0.013, for example 2039 build Strategic Strike & Missile Defence (20 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 +0.455 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 (32 simulations above 2).

retired_words (warn): e3-bra-random/report.md: 'simulations' 1 time(s), first near line 38; use 'simulations'.

The simulation furthest from the median (seed 33) ends −1.92 from it, with 7 shocks and 0 upside events [experiment_outlier_simulations].

Comparison

Against the hold experiment for the same nation (e3-bra-hold), the median index is +0.81 points apart, the median rank 29 against 34, 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].

What each decision and shock was worth

Counterfactual probes on the first 20 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.

Probe	Index	Score sum	For example
Hold instead of the method	−0.778	−56.7
No shocks	+0.847	+59.5
Replay of the recorded actions (must change nothing)	0.000	0.0

Settings and versions

Experiment cycle-001.e3-bra-random. Every simulation records the model, graph and parameter versions, the scenario, the method and its seed, so it can be reproduced exactly.

Nation: Brazil (BRA)
Position: The 2026 ratings of the National Capability Index
Method: Random. Five actions a round, each a random open group and mode and a random chunk of income.
Scenario: The shock and upside library, drawn at random each round
Objective: Capability index, the primary objective the experiment is judged on; every other objective is reported beside it
Horizon: 20 rounds, 2026 to 2046
Simulations: 100 seeds, 1 to 100. Every method in the batch faces the same draws for the same seed.
Graph elasticities: Drawn for each simulation, uniformly within each edge’s bracket
Income: Base credits 386.4 a round, moving with the economic groups
Versions: Model 0.1.0, Capability Dependency Graph 0.2.0, parameters 0.1.0
Batch: Improvement cycle (cycle-001), cycle 1 of the improvement loop
Runtime: 7.0 seconds in all; 1045 microseconds a round

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.
