Adds a precompute script (build_permanence_risk.mjs) that summarizes per-state reversal risk from the committed series into a small permanence_risk.json (49 states), and a self-contained CONUS choropleth (PermanenceMap.jsx) that shades each state by how far its disturbance- exposed reserve falls below the passive reserve at horizon. Click a state to load it. Wired into the Permanence tab above the per-state panel. Build verified; values cross-checked (ME 66%, IN 84%, GA 48%).
Stress test found NV's reversal at -179% (disturbance-exposed median above passive) because its forested carbon base is tiny (15 Tg sparse woodland) — the known NV edge case. Precompute now marks states with a small base or negative shortfall reliable:false; the choropleth grays them out instead of mis-coloring them low-risk, and the per-state view shows a 'not characterized' note. NV and RI flagged. Build verified.

What
Follow-up to #75. Adds the CONUS choropleth promised in the roadmap.
scripts/build_permanence_risk.mjsprecomputes a small per-state reversal-risk summary (public/api/permanence_risk.json, 49 states) from the committed series, so the map reads one ~10 KB file instead of loading 48 state series in the browser.src/PermanenceMap.jsxis a self-contained CONUS choropleth (Albers projection mirrored from SVGMap) that shades each state by the disturbance-exposed reserve shortfall vs the passive reserve at horizon; click a state to load it.Base
Stacked on
feat/permanence-reversal-risk(#75) so the diff here is just the map + data. Merge #75 first, then this.Risk
npm run buildpasses; the precompute is reproducible vianode scripts/build_permanence_risk.mjs.Opened for review — not auto-merged.
