+# OpenSpec Change: enterprise-react-map
+
+- **Change ID**: enterprise-react-map
+- **Package**: `@suaveplan/react-map`
+- **Category**: react
+- **Target path**: `react/platform/react-map`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/react-map.md`
+

+
+## Summary
+
+Deliver `@suaveplan/react-map` on genesis from scratch at enterprise quality. A headless, provider-agnostic mapping layer: `useMap` hook owns map state (center, zoom, bounds, markers, polygons, clusters); component primitives (`MapView`, `MapContainer`, `Marker`, `MarkerCluster`, `Polygon`) render via a typed `MapAdapter` interface. Genesis adds the first concrete adapters (MapLibre GL + Leaflet), a bundled clustering algorithm, geo math helpers (`haversine`, `boundsUnion`, `pointInPolygon`), Storybook for every component, accessibility (keyboard pan/zoom, `role="application"`), i18n for ARIA labels, and Playwright E2E.

+
+## Current-state audit (genesis)
+
+Package does not exist on genesis — fresh build.
+
+---
+
+## Available workspace deps on genesis
+
+| Package | Role |
+|---|---|
+| `@suaveplan/error` (`workspace:^`) | `MapError` |
+| `@suaveplan/events` (`workspace:^`) | Map event bus |
+| `@suaveplan/react-translate` (`workspace:^`) | i18n for ARIA labels / tooltips |
+| `@opentelemetry/api` (`catalog:observability`) | Spans + counters |
+| `zod` (`catalog:forms`) | Config schemas |
+| `tslib` (`catalog:build`) | TS helpers |
+
+External: `maplibre-gl catalog:maps` (peer/optional), `leaflet catalog:maps` (peer/optional), React 18 peer.

+## Preserved public API surface
+
+```ts
+// Components
+MapView, MapContainer, Marker, MarkerCluster, Polygon
+
+// Hooks
+useMap, useMapContext
+
+// Adapters
+MapAdapter, MapLibreAdapter, LeafletAdapter
+createMapLibreAdapter, createLeafletAdapter
+
+// Utils
+haversine, boundsUnion, pointInPolygon, clusterMarkers, cn
+
+// Types
+LatLng, MapBounds, MapConfig, MapProps, MapContainerProps,
+MarkerData, MarkerProps, MarkerClusterData, MarkerClusterProps,
+PolygonData, PolygonProps, ClusterConfig, MapEventMap,
+UseMapReturn, MapAdapterOptions
+```
+

+
+## New additions for genesis
+
+1. **`MapError`** — codes: `MAP_ADAPTER_INIT_FAILED`, `MAP_RENDER_FAILED`.
+2. **`MapAdapter` interface** — typed contract enabling swap of vendor SDKs.
+3. **`MapLibreAdapter` + `LeafletAdapter`** — first reference implementations; peer-dep gated.
+4. **Clustering algorithm** — `clusterMarkers(markers, config)` grid/supercluster-style in `src/utils/cluster.ts`.
+5. **Geo math** — `haversine`, `boundsUnion`, `pointInPolygon` in `src/utils/geo.ts`.
+6. **Storybook** — stories for `MapView`, `Marker`, `Polygon`, `MarkerCluster`, `MapContainer`, `useMap` playground.
+7. **Accessibility** — keyboard pan/zoom (arrow keys, `+`/`-`), `role="application"`, screen-reader marker descriptions.
+8. **Playwright E2E** — pan, zoom, marker click, cluster expand, polygon draw.
