# 11.f-subsystem-parameter-lab Checklist

## Purpose

Deliver a lab that demonstrates startup from a subsystem descriptor provided directly as a parameter.

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

## Focus

- Descriptor-direct startup
- Explicit subsystem without SAR
- Development/test control

## Step

- Show that a subsystem descriptor can be supplied directly on the CLI and resolved with an external packaged component directory.

## Checklist

- [x] Descriptor-direct startup is implemented
- [x] The README explains the role of the descriptor parameter
- [x] `samples/11.f-subsystem-parameter-lab/README.md` is updated to match the implementation

## Exit Criteria

- [x] Build succeeds
- [x] CLI execution works
- [x] Descriptor-direct subsystem behavior is confirmed
