title: "Supply Chain"
description: "Shipping-stress composite, carrier and ETF tracking, critical minerals, chokepoint cards, and the Scenario Engine trigger — one command surface."
---

The **Supply Chain** panel (internal id `supply-chain`) is the main entry point for everything supply-chain related: a composite shipping-stress score, carrier and ETF rows with price movement, a minerals concentration view, and — most importantly — the **[Scenario Engine](/scenario-engine)** trigger buttons that let PRO users activate pre-built disruption scenarios across the map and the panel state.

## What the panel shows

Across the composite:

- **Shipping-stress header** — a composite-stress score (0–100) with a tinted gauge, colour-bucketed by level (`critical` / `elevated` / `moderate` / `normal`).
- **Carrier / ETF / index rows** — per-symbol price, per-cent change (`▲`/`▼` arrow with bullish/bearish tint), a compact sparkline, and a type badge (`ETF` / `IDX` / `CARR`).
- **Critical minerals rows** — per-mineral top-3 producer concentration, HHI, and risk rating (`critical` / `high` / `moderate` / `low`).
- **Scenario Engine trigger cards** — per-scenario trigger buttons (`sc-scenario-trigger` / `sc-scenario-btn`) that dispatch a template id to the scenario worker. Free users see the buttons but hit the PRO gate at activation. Scope-all scenario runs use the v1 seeded reporter set (`US`, `CN`, `RU`, `IR`, `IN`, `TW`). See [Scenario Engine](/scenario-engine) for the full workflow.
- **Active-scenario banner** (when a scenario is running) — icon, scenario name, optional params chip (duration + cost bump), top impacted countries, dismiss ×. When template parameters are populated, an additional "Simulating …" tagline renders. Banner construction lives in `renderScenarioBanner()` in `src/components/SupplyChainPanel.ts`.

Panel id is `supply-chain`; canonical component is `src/components/SupplyChainPanel.ts`. Title per variant: "Supply Chain" (full/finance) or "Supply Chain & Logistics" (commodity).

## How you reach it

- **Cmd+K**: type *supply chain*, *shipping*, or *logistics*.
- **Availability by variant**: registered and enabled by default in the **full/geopolitical** (priority 1), **finance** (priority 1), and **commodity** (priority 1) variants. Not present in the tech or happy variants. Source: `'supply-chain'` entries in `FULL_PANELS`, `FINANCE_PANELS`, `COMMODITY_PANELS`. On desktop the full-variant registration additionally layers `premium: 'enhanced'` (`_desktop &&` clause in `src/config/panels.ts`).

## Data sources

The panel and adjacent supply-chain workflows mix generated sebuf REST RPCs, bootstrap/shared-store first paint, and special platform routes. The main Supply Chain panel reads cached bootstrap payloads for composite stress, chokepoints, shipping rates, and minerals when available, then refreshes through the generated `SupplyChainService` RPCs.

Special platform routes used from this surface:

| Surface | Method + route | Feeds |
|---|---|---|
| Scenario activation | `POST /api/scenario/v1/run-scenario` | PRO Scenario Engine trigger buttons dispatch a template id and parameters. |
| Scenario status | `GET /api/scenario/v1/get-scenario-status` | Scenario Engine polling paints the active-scenario banner after worker completion. |

See [Scenarios API](/api-scenarios) for the full async job contract.

## Refresh cadence

Panel reads on mount and on user-triggered refresh. Scenario Engine jobs are async; the panel polls the job status endpoint and paints the banner once the worker writes `status: "done"`.

## Tier & gating

The Supply Chain panel itself is **free** on web (full / finance / commodity variants). On desktop, the full-variant registration layers `premium: 'enhanced'`. **The Scenario Engine activation is PRO** regardless of web vs desktop — free users see the trigger buttons but hit the `scenario-engine` gate on activation.
