# OpenSpec Change: enterprise-react-port-tracking

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

---

## Summary

Deliver `@suaveplan/react-port-tracking` on genesis from scratch at enterprise quality. React surface for `@suaveplan/ports`: composite components (`PortMap`, `VesselTracker`, `ShippingLaneOverlay`, `PortMarker`, `ETAPanel`, `PortInfoCard`) and hooks (`usePortSearch`, `useShippingLanes`, `useETAEstimate`, `useVesselTracking`). Genesis closes test gaps for `PortMap`, `ShippingLaneOverlay`, `VesselTracker`, `useVesselTracking`, and `portIconPaths` (all missing from main branch), aligns `PortMap` on top of `@suaveplan/react-map` primitives, adds i18n via `@suaveplan/react-translate`, Storybook for every component, and Playwright E2E for live vessel tracking.

## Current-state audit (genesis)

Package does not exist on genesis — fresh build.

## New additions for genesis

1. **`PortTrackingError`** — codes: `PORT_SEARCH_FAILED`, `VESSEL_TRACK_FAILED`, `ETA_ESTIMATE_FAILED`.
2. **`PortMap` on `react-map` primitives** — aligned on `MapView`, `Marker`, `Polygon` from `@suaveplan/react-map`.
3. **i18n** — `@suaveplan/react-translate` for ETA labels ("Arriving", "Delayed"), facility lists, all ARIA strings.
4. **Missing tests** — `PortMap`, `ShippingLaneOverlay`, `VesselTracker`, `useVesselTracking`, `portIconPaths` all fully covered.
5. **Storybook** — stories for every component + hooks playground.
6. **Playwright E2E** — live vessel stream, marker updates, ETA panel.
