# MVP-TASK-018 — Advance Queued to Preparing

**Status:** Done  
**Parent:** MVP-KDS-002-S01; MVP-HIST-001-S02

## Objective and required behavior

Provide a large-target fast forward operation from `Queued` to `Preparing`, persist it, append its
timestamped transition, and show immediate visible feedback.

## Scope, areas, and non-goals

Expected application transition policy/API/repository/UI card and tests. Exact gesture is
implementation-owned. No later states, backward corrections, or arbitrary state setter.

## Evidence and acceptance

Use both IDs in E2E and database integration. Accept when invalid/racing transitions cannot silently
corrupt state, history and current state agree, traceability/contracts are current, and inherited
DoD passes. Handoff records concurrency and timestamp source.
