| ## What it does |
|
|
| Vessels is the maritime intelligence domain pack for the SZL Holdings platform. It gives fleet operators, risk managers, and compliance teams a single command surface that correlates AIS telemetry, voyage economics, sanctions exposure, and AI-generated alerts — all governed by the same Proof Chain and Covenant Policy infrastructure that runs every SZL Holdings product. |
|
|
| Every anomaly surfaces a recommended action. Every sanctioned-entity match triggers an approval workflow. Every voyage P&L projection is traceable back to the signal that prompted it. |
|
|
| ## Run locally |
|
|
| ```bash |
| # From the monorepo root |
| pnpm install |
| pnpm --filter @workspace/api-server dev # Start the API server first |
| pnpm --filter @workspace/vessels dev |
| ``` |
|
|
| **Primary route:** `/vessels/` |
|
|
| > **Note:** AIS telemetry is simulated. Live AIS requires a paid provider subscription (~$15–40K/year). See [`docs/operations/known-gaps.md`](../../docs/operations/known-gaps.md). |
|
|
