 Unlike GitHub, a job whose steps run on the host (a `host` label without `container:`) starts no service containers, so `job.services` and `job.container` stay empty. Give such a job a `container:` when it needs services.
 
-#### Docker from a job (`GITEA_DOCKER_WORKSPACE`)
-
-A container a job starts through the Docker socket cannot bind-mount the workspace by the job's own path, the daemon does not have it. `GITEA_DOCKER_WORKSPACE` holds the path the daemon sees. Use it as the prefix of workspace binds, with `.` as the fallback for local use, here in a `docker-compose.yaml`:
-
-```yaml
-volumes:
-  - ${GITEA_DOCKER_WORKSPACE:-.}/data:/app/data
-```
-
-Linux container jobs use a Docker proxy when socket sharing and permissions allow it. Other setups use the daemon socket directly. The proxy removes containers, networks and volumes after post steps and the completed hook. Named volumes created through it are job-scoped. To retain resources, mount the daemon socket explicitly in `container.options`. Host jobs use their existing Docker access, where `.` works.
-
 #### Proxy

+# macOS VM executor
+
+The runner can execute a job in an ephemeral macOS VM by registering a
+`macos-vm` label:
+
+```yaml
+runner:
+  labels:
+    - macos-latest:macos-vm://registry.example.com/macos-15.2-xcode-26.1
+```
+
+The VM is created and managed by `runner-executor-macos`, a dedicated Swift
+binary built on Apple Virtualization.framework. The source VM must include the
+runner guest agent.
+
+## Configuration
+
+```yaml
+macos_vm:
+  executor_path: runner-executor-macos
+  workdir_parent: /Users/admin/runner
+  cpu: 0
+  memory: 0
+  boot_timeout: 5m
+```
+
+`workdir_parent` is the guest directory under which job workspaces are created.
+`executor_path` is the binary to invoke; an empty value uses PATH lookup.
+
+## Executor CLI
+
+The runner uses a narrow, runner-oriented command set:
+
+```text
+runner-executor-macos provision <image> <name> [--cpu N] [--memory MB]
+runner-executor-macos start <name> [--no-graphics]
+runner-executor-macos exec <name> [--stdin] <argv...>
+runner-executor-macos stop <name> [--timeout N]
+runner-executor-macos destroy <name>
+runner-executor-macos list --format json
+runner-executor-macos version
+```
+
+`list --format json` returns:
+
+```json
+[
+  {
+    "name": "GITEA-MACOS-VM-<runner-uuid>-...",
+    "state": "stopped",
+    "running": false,
+    "accessed_at": "2026-09-05T12:00:00Z"
+  }
+]
+```
+
+## Integration test
+
+The end-to-end test is opt-in because it provisions and boots a real VM:
+
+```bash
+MACOS_VM_TEST_IMAGE=/path/or/reference \
+  go test -tags macos_vm_integration ./act/container -run '^TestMacOSVMEnvironmentIntegration$' -v
+```
+
+The test skips when `MACOS_VM_TEST_IMAGE` is unset.
+
+## Orphaned VM cleanup
+
+Job VM names start with `GITEA-MACOS-VM-<runner-uuid>-`. While the runner is
+idle, it lists local VMs and destroys the non-running ones whose name has this
+runner's UUID and whose access time is older than
+`runner.workdir_cleanup_age`.
+
+## Service containers
+
+Service containers are intentionally rejected for macOS VM jobs today. Docker
+service containers live on a Docker network and are reached by workflow service
+id, which a macOS VM cannot resolve.
+
+Possible future designs:
+
+1. **Host-published Docker services + guest host mapping** — publish each
+   service port on the runner host and inject `<service-id> -> <host-ip>` into
+   the VM through the guest agent.
+2. **macOS VM services** — run each service as another VM; this requires
+   service discovery and is much heavier than Docker containers.
+3. **Environment-based discovery** — require workflows to read service
+   addresses from env vars instead of hostnames, breaking GitHub Actions
+   compatibility.
+
+Option 1 is the most compatible direction once the guest agent and host network
+configuration are stable.
