# 04.a-designed-sync-command-lab Checklist

## Purpose

Deliver a lab that shows a command designed for synchronous execution as part of the application contract.

Stage Status:
- Current status: `DONE`
- Owner: `Codex + human`
- Update rule: `Update this block whenever a checklist item changes state.`

## Focus

- designed-sync command
- immediate command result
- difference from job-backed command execution

## Step

- Add a follow-up lab to `06-cqrs` for a command that is synchronous by design.

## Checklist

- [x] The lab is clearly separate from `06-cqrs`
- [x] The lab is clearly separate from future test-only sync execution work
- [x] One command is synchronous by design
- [x] The immediate command result is verified
- [x] `samples/06.a-designed-sync-command-lab/README.md` is updated to match the implementation

## Exit Criteria

- [x] Build succeeds
- [x] CLI execution works
- [x] Designed-sync command behavior is confirmed
- [x] README is complete
