# 03-operation Plan

- date: 2026-04-01
- status: in_progress

## Purpose

Prepare a sample track for operation contract modeling in CML.

This lab is intended to exercise:

- `OPERATION`
- `INPUT`
- `OUTPUT`
- `TYPE`
- `SUMMARY`
- `DESCRIPTION`

## Current Status

The first line sample is:

- `SERVICE > OPERATION`
- `INPUT > TYPE`
- `OUTPUT > TYPE`
- `SUMMARY`
- `DESCRIPTION`
- query-only `greeting(name) -> message`

Remaining:

- nested `VALUE` under `INPUT` / `OUTPUT`
- `SERVICE > OPERATION` verification
- command pattern lab
- entity-integrated lab
