Architecture

The whole stack

One conversation repairs a disrupted trip and prosecutes the aftermath.

APIs where they exist. Phone calls where they don’t. Sabre and PayPal are called directly where they expose an API; the claim counterparty is phone-only, so Winston places a live agent-to-agent call instead. Click any node — or let the tour drive.
