Maths, slowly, with sources.
Three teaching instruments make the doctrine auditable: a trade-gravity board, a composite index, and a coupled-oscillator diagram. All coefficients cited; all weights adjustable; all readings descriptive and snapshot-only.
A standing observatory updated per era-week with vendored Tier-A snapshots — never a live ticker, never a forecast, never a tradeable signal.
- Illustrative teaching instruments with cited coefficients.
- Slider-driven so the reader audits sensitivity, not us.
- Snapshot per era-week from public Tier-A datasets.
- A forecast of trade, treaties, or political outcomes.
- A scoring system for MPs, parties, firms, or governments.
- A scraped live feed or a real-time data product.
Tinbergen-style gravity equation with cited Head & Mayer 2014 coefficients. Sliders for each lawful-corridor factor.
Six sub-indices — legal, language, diaspora, treaty, accountability, ocean — composed with auditable weights.
Coupled-oscillator teaching diagram for the UK ↔ Eelam phase-lag through colonial, war and reception eras.
Civilian ocean-science alignment with UN Ocean Decade, UNCLOS Part XIII and UNESCO 2001 UCH. Area-level only.
