Uneven profile — 30-point spread from Economy to Institutional Integrity. No archetype rule matches that shape. This is a reading of the sourced stats — not a data gap.
SourceDerivedMethodRule-based classificationConfDeterministic✓ ReconstructableⓘArchetypes are derived automatically from the leadership stat profile — not hand-assigned. "No distinct archetype" means no classification rule matched; profile shape is assessed separately from the best-to-worst spread. A leader lacking enough sourced stats reads as "No data". A secondary archetype is added only when a stat scores exceptionally high.

ⓘLegacy Rating is the completed-tenure rating derived from sourced leadership dimensions and the recorded conditions of that tenure — on the published scale a score near 60 means the country broadly matched the benchmark trajectory over the mandate.

Source: World Bank + derived·Method: Contribution·✓ ReconstructableⓘEach dimension measures change under the leader relative to global trends — how the indicator moved over their tenure, net of the world's move over the same window — not the country's absolute level. A score near 60 means performance broadly matched the benchmark trajectory; above = improved the country's standing, below = declined. Governance / Economy / Politics / Institutional Integrity from World Bank WGI, WDI and V-Dem trajectories; Vision from the country's innovation rank (WIPO patents + UNESCO tertiary), former leaders only (patents lag ~3 years); Crisis Response (World Bank + UCDP + WGI, an absolute response-quality scale) and Communication (GDELT) from tenure signals; Diplomacy (Diplomatic Conduct) is active-only. A tenure under six months, or an indicator whose series hasn't reached the term, shows as no data. Full model on the Methodology page.

Source: World Bank WGI + V-Dem + derived·Method: Stewardship·✓ ReconstructableⓘMeasures whether strong institutions inherited at the start of the tenure were preserved, improved or eroded. It does not reward the leader for inheriting a strong country. A metric qualifies only when the inherited baseline was at least 75 on its normalized scale; the score is the world-net change over the tenure on the single public scale (60 = preserved relative to global movement). Requires two or more eligible sourced groups, the six-month tenure floor and a post-tenure-start observation — otherwise No data, never a zero. Weights mirror the current-form groups (gov 0.17 · pol 0.15 · int 0.08 · vis 0.09), renormalized over what is eligible and sourced.
