## A

* **Async Execution** — Running operations without waiting for completion. Use `wait=false` and poll with `get_operation` or `wait_operations`.

## D

* **Directory State** — A snapshot of local files synced with `rsync`. Identified by `directory_state_id`.
* **Disposable** — When `disposable=true` (default), filesystem changes are discarded after command execution.

## I

* **Image** — An immutable filesystem snapshot. Identified by UUID.
* **Image Lineage** — The parent-child relationships between images. View with `contree://image/{uuid}/lineage`.

## M

* **MCP (Model Context Protocol)** — The protocol used for AI agent tool communication.
* **MicroVM** — A lightweight virtual machine used for isolated command execution.

## O

* **Operation** — A running or completed task (command execution or image import). Identified by `operation_id`.

## R

* **Result Image** — The image UUID returned when running with `disposable=false` and filesystem changes occur.
* **Root Image** — An image imported from a container registry, with no parent.

## T

* **Tag** — A human-readable name for an image (e.g., `python:3.11`). Tags can point to different UUIDs over time.

## U
