# Post Initial Tier Compute

`POST /api/triage/initial-tier/compute`

## Request

- Base URL: `https://app.archangelhealth.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://app.archangelhealth.ai/api/triage/initial-tier/compute`
- Auth: none declared

Stateless preview — no persistence, no events. Pass-4 PRD §3.1
treats `compute` as a clinical write surface (the surgeon's workflow
decision tool), so NP/PA is blocked even though it's read-only at the
storage layer.
