Plans scored for everyone they affect.

teleon.dev/docs/council convenes 12 personas for humanity and stakeholder welfare, who score each plan on a Rawlsian-Nash social welfare index with hard harm vetoes. The council is part of the funnel that narrows a trillion scenario combinations to a Pareto frontier.

Three plans before the council

PlanWelfare index

1Plan B: phased rollout74lowest persona score 58Leads

2Plan A: fast rollout66lowest persona score 41

3Plan C: full automation70harm veto from one personaVetoed

Plan B leads because its worst-off persona fares best. Plan C scores higher than A, and a harm veto stops it.

What it does

Twelve personas

Each persona speaks for humanity or one stakeholder group and scores the plan from that view.

A Rawlsian-Nash index

The index counts gains for the worst-off group first, then rewards gains shared across every group.

Hard harm vetoes

A veto stops a plan outright, whatever its index score.

The contract

A council verdict lists each persona's score, the welfare index and every veto with its reason.

Full glossary

Welfare index: One score for how a plan treats everyone it affects. The Rawlsian-Nash form puts the worst-off group first and rewards balanced gains.
Harm veto: A hard stop: one persona can halt a plan that crosses a harm limit, whatever its index score.
Pareto frontier: The set of options where improving one measure, such as cost, would worsen another, such as quality.
