# 02.b-simpleentity-crud-lab implementation record

## Scope

This line is the `SimpleEntity` variant of the base `04-crud` sample.

The first completion target is:

1. one `SimpleEntity`-based CRUD model generates a component
2. one shell-visible component help route works
3. one shell-visible service help route works
4. one shell-visible operation help route works
5. one metadata route explains the generated runtime surface

## Implemented

- sample source under `/Users/asami/src/dev2026/cncf-samples/samples/04.b-simpleentity-crud-lab`
- setup-first command flow
  - `../../bin/setup cozy`
- shell-first runtime commands through `bin/cncf`
  - `command help simple-entity-crud-lab`
  - `command help simple-entity-crud-lab.item`
  - `command help simple-entity-crud-lab.item.create-item`
  - `command simple-entity-crud-lab.meta.describe --format yaml`

## Verified Result

- `sbt --batch clean compile` succeeds
- component help succeeds
- service help succeeds
- operation help succeeds
- metadata describe succeeds
- `run.sh` succeeds
- `cozy` scripted fixture succeeds with `SIMPLEENTITY_CRUD_SURFACE_OK`

## Position

This sample keeps the same CRUD inspection line as `04-crud`, but uses the `SimpleEntity` inheritance variant of the model.

Its generated-surface inspection line is also covered by `cozy` scripted under `simpleentity-crud-surface`.
