Description
Add power index overlay to folk-trust-sankey.ts right-column nodes.
What
Right-column delegate nodes currently show rank badge + received weight %. Add a second bar showing Banzhaf power %, creating a visual comparison: raw weight vs actual coalitional power.
Primitive
- Fetch power indices once on authority change:
GET /rnetwork/api/power-indices?space={space}&authority={authority}
- Build
Map<did, { banzhaf, shapleyShubik }> lookup
- Right-column nodes get dual horizontal bars:
- Top bar (gray): raw received weight %
- Bottom bar (authority color): Banzhaf power %
- Nodes where power >> weight glow red (disproportionate influence)
Implementation
folk-trust-sankey.ts: Add powerMap field, fetch in loadData()- Modify
renderRightNodes() to draw second bar below weight bar
- Add CSS for
.power-bar with transition animation
- ~60 lines, one fetch, zero new files
Acceptance Criteria
