 Layer 4 entry point for the workflow engine. The `uwf` binary orchestrates one step per invocation: load thread head from `threads.yaml`, run the moderator, spawn the configured agent CLI, run extract, append a CAS step node, and update the head pointer (or archive when `$END`).
 
+### Four-Layer Architecture
+
+```
+workflow → thread → step → turn
+模板定义   执行实例   单步结果   agent内部交互
+```
+
+- **Workflow** (layer 1): YAML template with roles and routing graph
+- **Thread** (layer 2): Single workflow execution instance
+- **Step** (layer 3): One moderator→agent→extract cycle
+- **Turn** (layer 4): Agent-internal interactions (use `step read` or CAS to inspect)
+
 This package has no library `src/index.ts` — it is consumed as a CLI binary only.
 
 **Dependencies:** `@uncaged/json-cas`, `@uncaged/json-cas-fs`, `@uncaged/workflow-agent-kit`, `@uncaged/workflow-moderator`, `@uncaged/workflow-protocol`, `@uncaged/workflow-util`, `commander`, `dotenv`, `yaml`

+| `uwf thread exec <thread-id> [--agent <cmd>] [-c <count>] [--background]` | Execute one or more moderator→agent→extract cycles |
 | `uwf thread show <thread-id>` | Show thread head pointer |
-| `uwf thread list [--all]` | List active threads (`--all` includes archived) |
-| `uwf thread steps <thread-id>` | List all steps chronologically |
+| `uwf thread list [--status <idle\|running\|completed>]` | List threads, optionally filtered by status |
 | `uwf thread read <thread-id> [--quota N] [--before <hash>] [--start]` | Render thread as readable markdown |

+## Migration Guide
+
+### Breaking Changes (v0.x → v1.x)
+
+The CLI was reorganized to clarify the four-layer architecture. **No backward compatibility** — old commands have been removed.
+
+#### Renamed Commands
+
+| Old Command | New Command | Notes |
+|------------|-------------|-------|
+| `workflow put` | `workflow add` | More intuitive verb |
+| `thread step` | `thread exec` | Eliminates ambiguity with "step" noun |
+| `thread list --all` | `thread list --status completed` | Unified status filtering |
+
+#### Removed Commands (Merged)
+
+| Old Command | New Command | Notes |
+|------------|-------------|-------|
+| `thread running` | `thread list --status running` | Merged into unified list |
+
+#### Removed Commands (Split)
+
+| Old Command | New Commands | Notes |
+|------------|-------------|-------|
+| `thread kill` | `thread stop` or `thread cancel` | `stop` keeps thread active, `cancel` archives it |
+
+#### Moved Commands
+
+| Old Command | New Command | Notes |
+|------------|-------------|-------|
+| `thread steps` | `step list` | Moved to step layer |
+| `thread step-details` | `step show` | Moved to step layer |
+| `thread fork` | `step fork` | Moved to step layer (forks are step-based) |
+
+#### Deprecation Errors
+
+Old commands now show helpful error messages:
+
+```bash
+$ uwf thread step 01ARZ3NDEKTSV4RRFFQ69G5FAV
+Error: Command 'thread step' has been removed.
+Use 'thread exec' instead.
+
+For more information, see: uwf help thread exec
