# Dock is busy

> **Reserved** — this code is approved and frozen, but no production route can emit it yet. It is live today in the sandbox reference implementation — see the `servers` entry and `x-sandbox` extension in the spec.

**Status:** `409`

**`field` member:** never present

**Source:** `route`

Reserved for the future dock-command route (POST /api/v1/docks/`{dockId}`/commands): the dock already has an in-flight command. A 423 (WebDAV Locked) was considered instead — see 'Decisions awaiting sign-off' #6 in README; 409 chosen for HTTP-client-library familiarity. Approved 2026-08-03; born live in the sandbox reference implementation (contracts/openapi.json x-sandbox) — the production route is pending viam task 3.6.
