fix: revert output protocol changes from #385

Agent CLI outputs plain CAS hash (not JSON), engine parses plain hash.
StepOutput no longer carries sessionId — session info is already in CAS detail.
Keeps the valuable parts of #385: sessionId in AgentRunResult (process-internal),
continue support, and frontmatter retry loop.

 ## Project Overview
 
-This monorepo implements a workflow engine that executes single-file ESM bundles. Each workflow is a self-contained `.esm.js` file with an XXH64 hash as its version identifier. Shared types live in `@uncaged/workflow-protocol`; bundle authors typically depend on `@uncaged/workflow-runtime`.
+This monorepo implements a stateless workflow engine driven by a single-step CLI (`uwf`). Workflows are **YAML definitions** stored as CAS nodes; threads are immutable chains of CAS-linked step nodes. No daemon — each `uwf thread step` invocation runs one moderator→agent→extract cycle and exits.
 
 ### Key Terms
 
 | Concept | What it is |
 |---------|-----------|
-| **Workflow** | A single-file ESM module that exports `run` (workflow function) and `descriptor` (metadata). Identified by its XXH64 hash (Crockford Base32). |
-| **Bundle** | The physical `.esm.js` file stored in `~/.uncaged/workflow/bundles/`. |
-| **Thread** | A single execution of a workflow, identified by a ULID. State lives in CAS (linked nodes); active threads indexed in `threads.json`; completed rows in `history/*.jsonl`. Debug logs use `.info.jsonl`. |
-| **Role** | A named actor within a workflow. Each role produces output with typed `meta`. |
-| **Registry** | `workflow.yaml` — maps workflow names to current/historical bundle hashes. |
+| **Workflow** | A YAML definition (`WorkflowPayload`) with roles, conditions, and a routing graph. Stored as a CAS node, identified by its XXH64 hash. |
+| **Thread** | A single execution of a workflow, identified by a ULID. State is an immutable CAS chain; active threads indexed in `threads.yaml`; completed threads in `history.jsonl`. |
+| **Role** | A named actor within a workflow. Each role has a system prompt and a JSON Schema `outputSchema`. |
+| **Moderator** | JSONata-based graph evaluator — determines the next role (or `$END`) with zero LLM cost. |
+| **Agent** | An external CLI command (`uwf-hermes`, etc.) spawned by `uwf thread step`. Produces frontmatter markdown output. |
+| **CAS** | Content-Addressed Storage via `@uncaged/json-cas` — all workflow definitions, thread nodes, and outputs are immutable CAS nodes. |
+| **Registry** | `~/.uncaged/workflow/registry.yaml` — maps workflow names to current CAS hashes. |

-A workflow engine that executes single-file ESM bundles. Each workflow is a self-contained `.esm.js` file identified by its XXH64 hash (Crockford Base32).
+A stateless workflow engine driven by a single-step CLI. Workflows are YAML definitions with roles, JSONata routing conditions, and a directed graph. Threads are immutable CAS-linked chains — each `uwf thread step` runs one moderator→agent→extract cycle and exits.
 
-## Core Concepts
+## Package Map
 
-| Concept | Description |
-|---------|-------------|
-| **Workflow** | A single-file ESM module exporting `run` (workflow function) and `descriptor` (metadata). Identified by its XXH64 hash. |
-| **Bundle** | The physical `.esm.js` file stored in `~/.uncaged/workflow/bundles/`. |
-| **Thread** | A single execution of a workflow, identified by a ULID. CAS-backed chain plus `threads.json` / `history/*.jsonl`; `.info.jsonl` for debug logs. |
-| **Role** | A named actor within a workflow. Each role produces output with typed `meta`. Roles live inside template packages (`src/roles/`). |
-| **Registry** | `workflow.yaml` — maps workflow names to current/historical bundle hashes. |
-| **CAS** | Content-Addressed Storage — bundles are immutable and addressed by hash. |
+| Package | npm | Role |
+|---------|-----|------|
+| `cli-workflow` | `@uncaged/cli-workflow` | `uwf` CLI binary — thread lifecycle, workflow registry, CAS inspection, setup |
+| `workflow-protocol` | `@uncaged/workflow-protocol` | Shared TypeScript types (`WorkflowPayload`, `StepNodePayload`, `WorkflowConfig`, etc.) |
+| `workflow-moderator` | `@uncaged/workflow-moderator` | JSONata graph evaluator — determines next role or `$END` |
+| `workflow-agent-kit` | `@uncaged/workflow-agent-kit` | `createAgent` factory, context builder, two-layer extract pipeline |
+| `workflow-agent-hermes` | `@uncaged/workflow-agent-hermes` | `uwf-hermes` agent — spawns Hermes chat, captures session |
+| `workflow-util` | `@uncaged/workflow-util` | Crockford Base32, ULID, logger, frontmatter parsing |

 ## Overview
 
-A workflow engine that executes single-file ESM bundles. Each workflow is a self-contained `.esm.js` file identified by its XXH64 hash (Crockford Base32). No daemon — processes start on demand and exit when done.
+A stateless workflow engine driven by a single-step CLI. Workflows are YAML definitions stored as CAS nodes; threads are immutable chains of CAS-linked step nodes. No daemon — each `uwf thread step` invocation runs one moderator→agent→extract cycle and exits.
 
-The implementation lives in **15** Bun workspace packages under `packages/`, using the `workspace:*` protocol.
+The implementation lives in **6** active packages under `packages/`, plus two external CAS packages (`@uncaged/json-cas`, `@uncaged/json-cas-fs`). Legacy packages reside in `legacy-packages/` and are not part of the active stack.

+Workflows are **YAML files** (not ESM bundles). `uwf workflow put <file.yaml>` parses the YAML, registers output schemas as JSON Schema CAS nodes, and stores the `WorkflowPayload` as a CAS node.
 
-## Package roles (detail)
+Example (`examples/solve-issue.yaml`):
 
-- **`workflow-protocol`** — Pure types (`WorkflowFn`, contexts, `CasStore` interface, descriptor shapes), `START` / `END`, `ok` / `err`. Depends only on peer `zod` for schema-related types in signatures.
-- **`workflow-runtime`** — Workflow author surface: `createWorkflow` from `src/create-workflow.js`, re-exports protocol types/constants used when authoring bundles.
-- **`workflow-util`** — Cross-cutting utilities: Crockford Base32, ULID, `createLogger`, `getDefaultWorkflowStorageRoot`, `getGlobalCasDir`, ref normalization; re-exports `ok`/`err` from protocol.
-- **`workflow-cas`** — Filesystem CAS (`createCasStore`), `hashString` / `hashWorkflowBundleBytes`, Merkle node serialization and helpers (`merkle.js`).
-- **`workflow-register`** — Bundle pipeline (`validateWorkflowBundle`, `extractBundleExports`, descriptor builders), registry YAML read/write, `resolveModel` / `splitProviderModelRef`.
-- **`workflow-execute`** — `executeThread`, supervisor/worker wiring (`engine/`), fork/GC/pause gate, `createExtract` + LLM extract helpers (`extract/`), `workflowAsAgent`. Imports `@uncaged/workflow-reactor` for LLM-backed extract/supervisor paths (`extract-fn.ts`, `supervisor.ts`).
-- **`workflow-reactor`** — `createLlmFn`, `createThreadReactor`, and thread tool-invocation types — consumed by `workflow-execute`.
-- **`cli-workflow`** — CLI commands and HTTP/dashboard-related wiring (`hono`, `yaml`); composes register + execute + CAS + util.
-- **`workflow-agent-*`** — Replaceable `AgentFn` implementations (Cursor / Hermes CLIs, or HTTP LLM).
-- **`workflow-util-agent`** — Shared prompt assembly and subprocess spawning for CLI agents.
-- **`workflow-template-*`** — Concrete `WorkflowDefinition` graphs + Zod role schemas + descriptor builders for publishing bundles.
-- **`workflow-dashboard`** — Standalone React UI; no published library entry matching `src/index.ts`.

+
+Key properties:
+
+- **`roles`** — inline role definitions; each `meta` is a JSON Schema (stored as its own CAS node on registration)
+- **`conditions`** — named JSONata expressions evaluated against the `ModeratorContext`
+- **`graph`** — `Record<Role | "$START", Transition[]>` — first matching transition wins; `condition: null` = fallback
+- **No agent binding** — agent selection is a deployment concern, configured in `config.yaml`
+- **No Zod** — all schemas are JSON Schema, validated through `@uncaged/json-cas`
 
 ## Three-phase engine loop
 
-Each role round is implemented in `packages/workflow-runtime/src/create-workflow.ts` (`advanceOneRound`): moderator → agent → extractor, with progressive context types from `@uncaged/workflow-protocol`.
+Each `uwf thread step` runs exactly one cycle: moderator → agent → extract. The CLI orchestrates this in `packages/cli-workflow/src/commands/thread.ts` (`cmdThreadStep`).
 
 ```

-│   Context: ModeratorContext { threadId, depth, start, steps }
-│   Action:  moderator(ctx) → role name | END
+│   Input:  WorkflowPayload + ModeratorContext { start, steps[] }
+│   Engine: JSONata conditions evaluated against the graph
+│   Output: next role name | $END

 ```
 
-### Context types (progressive)
+### Context types
 
 Defined in `packages/workflow-protocol/src/types.ts`:
 
 ```typescript
-type ModeratorContext<M> = ThreadContext<M>;
-type AgentContext<M> = ModeratorContext<M> & {
-  currentRole: { name: string; systemPrompt: string };
+type StepContext = {
+  role: string;
+  output: unknown;    // CAS node payload, expanded (not hash)
+  detail: CasRef;
+  agent: string;
+};
+
+type ModeratorContext = {
+  start: StartNodePayload;  // { workflow: CasRef, prompt: string }
+  steps: StepContext[];     // chronological, oldest first
+};
+
+type AgentContext = ModeratorContext & {
+  threadId: ThreadId;
+  role: string;
+  store: Store;
+  workflow: WorkflowPayload;
+  outputFormatInstruction: string;
 };
-type ExtractContext<M> = AgentContext<M> & { agentContent: string };
 ```
 
 ### Key properties
 
-- **Moderator is synchronous and pure** — no I/O, no state mutation inside `createWorkflow`’s moderator call path.
-- **Agent receives `AgentContext`** — reads `ctx.currentRole.systemPrompt`; raw output becomes `agentContent` for extract.
-- **Extractor is `WorkflowRuntime.extract`** — supplied by the engine from registry-resolved LLM config (`workflow-execute`); stores agent body in CAS and yields `contentHash` + `refs` on each step (`create-workflow.ts`).
-- **`extractPrompt` is a call parameter** on `RoleDefinition`, not implicit context state.
+- **Moderator** — pure JSONata evaluation; no LLM call, no I/O beyond CAS reads. Evaluates `workflow.graph[currentRole]` transitions in order, returns first match.
+- **Agent** — receives `AgentContext` with thread history + role system prompt + output format instruction. Raw output is frontmatter markdown.
+- **Extractor** — two-layer: tries frontmatter fast-path first (zero LLM cost), falls back to LLM extract if frontmatter is absent or invalid.
+- **Stateless** — each `uwf thread step` is an atomic, self-contained operation. No in-memory state between steps.
 
-## Agent information sources
+## Agent CLI protocol
 
-An agent has exactly three information sources:
+Each agent is an external command invoked by `uwf thread step`:
 
-1. **Prior knowledge** — LLM training, agent memory, agent skills
-2. **Thread context** — `AgentContext` (`start`, `steps`, `currentRole`)
-3. **Derived information** — from 1 & 2 (e.g. tool calls, shell commands)
-
-No hidden environment parameters. If an agent needs something (like a workspace path), it obtains it via `ExtractFn` (e.g. Cursor agent).
-
-## Bundle contract
-
-A workflow bundle is a single `.esm.js` file with two named exports (see `WorkflowFn` / `WorkflowDescriptor` in `packages/workflow-protocol/src/types.ts`):
-
-```typescript
-export const descriptor: WorkflowDescriptor;
-export const run: WorkflowFn;
-
-type WorkflowFn = (
-  thread: ThreadContext,
-  runtime: WorkflowRuntime,
-) => AsyncGenerator<RoleOutput, WorkflowCompletion>;
+```bash
+<agent-cmd> <thread-id> <role>
 ```
 
-`RoleOutput` carries `contentHash`, `meta`, and `refs` (agent text lives in CAS, addressed by hash).
+Contract:
+1. `uwf thread step` determines the next role via the moderator
+2. Agent CLI is spawned with `(thread-id, role)` as positional args
+3. `workflow-agent-kit` (`createAgent`) handles the boilerplate:
+   - Parses argv
+   - Loads `.env` from storage root
+   - Builds `AgentContext` by walking the CAS chain from `threads.yaml` head
+   - Resolves the role's `meta` schema and builds `outputFormatInstruction`
+   - Calls the agent's `run` function
+   - Runs two-layer extract on the raw output
+   - Writes `StepNode` to CAS (output + detail + prev link)
+   - Prints the new `StepNode` CAS hash to stdout
+4. `uwf thread step` reads stdout, updates `threads.yaml` head pointer, re-evaluates moderator for `done`
+5. Exit 0 = success, non-zero = failure
 
-### Constraints
+Agent resolution priority: `--agent` CLI override → `config.yaml` per-workflow/role override → `config.yaml` `defaultAgent`.
 
-- Single `.esm.js` file
-- No dynamic `import()` in bundles (loader exempt in engine)
-- Portable bundle static imports are constrained by validation in `@uncaged/workflow-register` (`validateWorkflowBundle`)
-- XXH64 hash (Crockford Base32) = version ID
+## Agent output format: frontmatter markdown (RFC #351)
 
-### Why AsyncGenerator?
+Agents produce **frontmatter markdown** — YAML frontmatter for structured meta, followed by a markdown body for content:
 
-- Each `yield` lets `workflow-execute` persist state, CAS rows, and enforce pause/abort
-- `return` supplies `WorkflowCompletion`
-- Fork replays historical steps into a new thread context
-- Bundle does not import the engine — only protocol/runtime types at build time
+```markdown
+---
+status: done
+next: reviewer
+confidence: 0.9
+artifacts:
+  - src/auth.ts
+scope: role
+---
+
+## Implementation
+
+Fixed the login redirect by updating the auth middleware...
+```
+
+The `outputFormatInstruction` (built by `buildOutputFormatInstruction` in `workflow-agent-kit`) is prepended to the role's system prompt, so the deliverable format is the first thing the agent sees. It lists the expected frontmatter fields derived from the role's `meta` JSON Schema.
+
+## Two-layer extract
+
+Structured output extraction uses a two-layer strategy (`workflow-agent-kit`):
+
+### Layer 1: frontmatter fast path (`frontmatter.ts`)
+
+1. Parse YAML frontmatter from raw agent output (`parseFrontmatterMarkdown`)
+2. Validate required fields (`validateFrontmatter`)
+3. Build a candidate object from frontmatter fields (`status`, `next`, `confidence`, `artifacts`, `scope`)
+4. `store.put()` the candidate against the role's `meta` schema
+5. Validate with `json-cas` schema validation
+6. If valid → return `outputHash` (zero LLM cost)
+
+### Layer 2: LLM extract fallback (`extract.ts`)
+
+If the fast path returns `null` (no frontmatter, invalid, or doesn't satisfy schema):
+
+1. Resolve extract model alias from config (`modelOverrides.extract` → `models.extract` → `defaultModel`)
+2. Call OpenAI-compatible chat completion with JSON mode
+3. System prompt: "Extract structured data matching this JSON Schema: ..."
+4. User message: the raw agent output
+5. Parse response, `store.put()`, validate
+6. Return `outputHash`
+
+## Prompt injection
+
+`workflow-agent-kit` prepends two pieces of context to the agent's system prompt:
+
+1. **Deliverable format instruction** — generated from the role's `meta` schema, tells the agent exactly what frontmatter fields to produce and the expected format
+2. **Scope constraint** — "Focus exclusively on YOUR role's deliverable. Do not perform actions outside your role's scope."
+
+This ensures agents produce parseable frontmatter output without requiring per-agent format knowledge.

+### Mutable state
+
+Only three files carry mutable state:
+
+| File | Contents |
+|------|----------|
+| `threads.yaml` | `Record<ThreadId, CasRef>` — maps active thread IDs to head node hash |
+| `history.jsonl` | Append-only log of completed threads (`thread`, `workflow`, `head`, `completedAt`) |
+| `registry.yaml` | Workflow name → current CAS hash |
+
+Everything else is immutable CAS content.
+
 ### ID encoding: Crockford Base32
 
 - Case-insensitive, filesystem-safe, no ambiguous chars (0/O, 1/I/L)
-- Bundle hash: XXH64 → 13-char
-- Thread ID: ULID → 26-char (10 timestamp + 16 random)
+- CAS hash: XXH64 → 13-char Crockford Base32
+- Thread ID: ULID → 26-char Crockford Base32 (10 timestamp + 16 random)
 
-### Registry (`workflow.yaml`)
+### Config (`config.yaml`)
 
-Managed by `@uncaged/workflow-register` (`readWorkflowRegistry`, `writeWorkflowRegistry`, …). Shape includes workflow entries and a top-level `config` section used for extract/supervisor model resolution.
+```yaml
+providers:
+  openrouter:
+    baseUrl: "https://openrouter.ai/api/v1"
+    apiKeyEnv: "OPENROUTER_API_KEY"
 
-### Thread storage (CAS + index)
+models:
+  sonnet:
+    provider: "openrouter"
+    name: "anthropic/claude-sonnet-4"
+  gpt4o-mini:
+    provider: "openai"
+    name: "gpt-4o-mini"
 
-Thread execution state is a chain of immutable CAS nodes (`StartNode`, `StateNode`, content Merkle blobs). Per bundle:
+agents:
+  hermes:
+    command: "uwf-hermes"
+    args: []
+  cursor:
+    command: "uwf-cursor"
+    args: []
 
-- **`threads.json`** — only in-flight threads (`head`, `start`, `updatedAt`).
-- **`history/{YYYY-MM-DD}.jsonl`** — completed threads (`threadId`, `head`, `start`, `completedAt`).
-- **CAS (`cas/`)** — payloads and refs for replay, GC, and fork sharing.
+defaultAgent: "hermes"
+agentOverrides:
+  solve-issue:
+    developer: "cursor"
 
-**`.info.jsonl`** — Structured debug log via `@uncaged/workflow-util` `createLogger`:
-
-```jsonc
-{ "tag": "4KNMR2PX", "content": "Loading bundle...", "timestamp": ... }
+defaultModel: "sonnet"
+modelOverrides:
+  extract: "gpt4o-mini"
 ```
 
-Tags are 8-char Crockford Base32 (40-bit random), one per call site. `grep "4KNMR2PX"` → code location.
-
-## Execution model
-
-- **No daemon.** `uncaged-workflow run <name>` starts a worker process (`workflow-execute` worker entry via `getWorkerHostScriptPath`)
-- Threads share bundle-scoped workers as implemented in CLI/engine
-- Pause/resume/abort via engine IPC and pause gate (`createThreadPauseGate`)
-

 ## Design decisions
 
 | Decision | Rationale |
 |----------|-----------|
-| **Role = pure data** | Decouples definition from execution; same role with different agents |
-| **Agent bound at runtime** | `WorkflowDefinition` is reusable; agent choice is deployment concern |
-| **Three-phase context** | Each phase sees only what it needs; types live in `workflow-protocol` |
-| **`WorkflowRuntime.extract` + CAS `contentHash`** | Large agent bodies deduplicated globally; Merkle roots summarize threads |
-| **`workflow-reactor` split** | LLM tool-calling loop isolated from filesystem/registry concerns |
-| **Single-file ESM** | Hash = version, self-contained bundle |
-| **No daemon** | OS handles process lifecycle |
-| **Crockford Base32** | Filesystem-safe, readable, compact |
-| **15-package split** | Clear boundaries: protocol ↔ runtime author API ↔ util/CAS/register ↔ execute ↔ CLI ↔ agents/templates/UI |
+| **YAML workflow definitions** | Human-readable, versionable, no build step required. JSON Schema inline in YAML, registered as CAS nodes on `workflow put`. |
+| **Stateless single-step CLI** | Each `uwf thread step` is atomic — no in-memory state, no daemon, no long-running process. OS handles lifecycle. |
+| **CAS-backed thread state** | Immutable linked nodes enable fork, replay, and GC without copying data. Content-addressed deduplication across threads. |
+| **JSONata moderator** | Declarative condition expressions evaluated against thread history. No LLM cost for routing decisions. |
+| **Frontmatter markdown output** | Agents produce structured meta (YAML frontmatter) alongside free-form content (markdown body). Enables zero-cost extraction when frontmatter is well-formed. |
+| **Two-layer extract** | Fast path avoids LLM calls when agents follow the format; LLM fallback handles messy output gracefully. |
+| **Prompt injection for format** | Output format instruction prepended to system prompt ensures agents produce parseable output without per-agent configuration. |
+| **JSON Schema (not Zod)** | Schemas are CAS-native data — storable, hashable, validatable through `json-cas`. No code generation, no runtime library dependency. |
+| **Agent as external command** | Agents are independent CLI binaries (`uwf-hermes`, `uwf-cursor`). Swappable per workflow/role via config. No tight coupling to the engine. |
+| **No daemon** | Process starts, does one step, exits. Simpler failure model, no connection management. |
+| **Crockford Base32** | Filesystem-safe, case-insensitive, readable, compact. |

+# 设计文档：office-agent 文档生成/编辑 Workflow 体系
+
+**日期：** 2026-05-18
+
+---
+
+## 概述
+
+在 monorepo 中新增三个包，实现通过 `office-agent` CLI 生成或编辑 Word 文档的完整 workflow 体系。
+
+| 包 | npm name | 职责 |
+|---|---|---|
+| `workflow-template-document` | `@uncaged/workflow-template-document` | 纯结构：角色定义、meta schema、调度表、descriptor |
+| `workflow-agent-office` | `@uncaged/workflow-agent-office` | writer 角色执行器：调用 `office-agent` CLI |
+| `workflow-agent-docx-diff` | `@uncaged/workflow-agent-docx-diff` | differ 角色执行器：调用 `docx-diff` CLI |
+
+Template 只定义结构，不含执行逻辑。执行器与 template 解耦。
+
+---
+
+## 一、`workflow-template-document`
+
+### Thread 启动输入
+
+```typescript
+// src/types.ts
+type DocumentStartInput = {
+  prompt: string;           // 用户指令
+  inputDocx: string | null; // null = 生成模式；本机绝对路径 = 编辑模式
+};
+```
+
+start.content 为 JSON `{ prompt, inputDocx }` 或纯文本（fallback：generate 模式，整段作为 prompt）。
+
+### 角色与 Meta
+
+`WriterMeta` 使用 discriminated union，在 schema 层区分两种模式：
+
+```typescript
+const writerMetaSchema = z.discriminatedUnion("mode", [
+  z.object({
+    mode: z.literal("generate"),
+    outputDocx: z.string(),   // 生成产物绝对路径
+    sourceDocx: z.null(),
+  }),
+  z.object({
+    mode: z.literal("edit"),
+    outputDocx: z.string(),   // 修改后产物：<outputDir>/modified.docx
+    sourceDocx: z.string(),   // 原始副本：<outputDir>/original.docx
+  }),
+]);
+type WriterMeta = z.infer<typeof writerMetaSchema>;
+
+// differ：仅编辑模式执行
+const differMetaSchema = z.object({
+  sourceDocx: z.string(),
+  modifiedDocx: z.string(),
+  diffDocx: z.string(),
+});
+type DifferMeta = z.infer<typeof differMetaSchema>;
+```
+
+两个角色的 `systemPrompt` 均为 `""`。
+
+### 调度表
+
+```
+START → writer ──(mode = "edit")──→ differ → END
+               ↘(mode = "generate")→ END
+```
+
+### 公开导出
+
+template 导出两个对象供消费方使用：
+
+- `documentWorkflowDefinition: WorkflowDefinition<DocumentMeta>` — 传入 `createWorkflow` 的 `def` 参数
+- `buildDocumentDescriptor(): WorkflowDescriptor` — bundle 导出用
+
+```typescript
+// bundle 侧用法
+export const descriptor = buildDocumentDescriptor();
+export const run = createWorkflow(documentWorkflowDefinition, { adapter, overrides });
+```
+
+### 包文件结构
+
+```
+packages/workflow-template-document/
+  src/
+    types.ts           # DocumentStartInput
+    roles/
+      writer.ts        # writerMetaSchema, WriterMeta, writerRole
+      differ.ts        # differMetaSchema, DifferMeta, differRole
+      index.ts
+    roles.ts           # DocumentMeta, documentRoles
+    moderator.ts       # writerIsEditMode condition + documentTable
+    definition.ts      # documentWorkflowDefinition
+    descriptor.ts      # buildDocumentDescriptor()
+    index.ts
+  __tests__/
+    moderator.test.ts
+  package.json
+  tsconfig.json
+```
+
+### 依赖
+
+```json
+{
+  "@uncaged/workflow-protocol": "workspace:^",
+  "@uncaged/workflow-runtime": "workspace:^",
+  "@uncaged/workflow-register": "workspace:^",
+  "zod": "^4.0.0"
+}
+```
+
+---
+
+## 二、`workflow-agent-office`
+
+### office-agent CLI 接口
+
+```bash
+# 生成模式：在 CWD 生成 output.docx
+office-agent create "<prompt>" -o output.docx
+
+# 编辑模式：在 CWD 对 modified.docx 进行修改（覆写）
+office-agent edit modified.docx "<instruction>"
+```
+
+- 两个命令均为阻塞调用（CLI 内部消费 SSE，退出即完成）
+- 输出文件落到调用方设定的 CWD
+- 退出码 0 = 成功，非零 = 失败
+
+### 文件命名约定
+
+| 模式 | 文件 | 路径 |
+|---|---|---|
+| generate | 输出 | `<outputDir>/output.docx` |
+| edit | 原始副本（workflow-owned 快照） | `<outputDir>/original.docx` |
+| edit | 修改后产物 | `<outputDir>/modified.docx` |
+
+edit 模式先将 `inputDocx` 复制为 `original.docx`（不可变快照），再复制为 `modified.docx`，对 `modified.docx` 调用 CLI。agent 覆写 `modified.docx`，`original.docx` 保持不变。differ 对比这两个 workflow-owned 文件，不依赖用户原始路径。
+
+### 执行流程
+
+**生成模式（`inputDocx = null`）：**
+1. `mkdir -p <outputDir>`（`<config.outputDir>/<ctx.threadId>`）
+2. `const command = config.command ?? "office-agent"`
+3. `spawnCli(command, ["create", prompt, "-o", "output.docx"], { cwd: outputDir, timeoutMs })`
+4. 验证 `outputDir/output.docx` 存在
+5. 返回 `JSON.stringify({ mode: "generate", outputDocx, sourceDocx: null })`
+
+**编辑模式（`inputDocx ≠ null`）：**
+1. `mkdir -p <outputDir>`
+2. `copyFile(inputDocx, <outputDir>/original.docx)`
+3. `copyFile(inputDocx, <outputDir>/modified.docx)`
+4. `const command = config.command ?? "office-agent"`
+5. `spawnCli(command, ["edit", "modified.docx", prompt], { cwd: outputDir, timeoutMs })`
+6. 验证 `outputDir/modified.docx` 存在
+7. 返回 `JSON.stringify({ mode: "edit", outputDocx: modifiedPath, sourceDocx: originalPath })`
+
+### AdapterFn 实现（直接实现，不经过 runtime.extract）
+
+CLI 产出确定性 JSON，直接 `schema.parse(JSON.parse(raw))` 跳过 LLM extraction：
+
+```typescript
+export function createOfficeAgent(config: OfficeAgentConfig): AdapterFn {
+  return <T>(_systemPrompt: string, schema: z.ZodType<T>) =>
+    async (ctx: ThreadContext, _runtime: WorkflowRuntime): Promise<RoleResult<T>> => {
+      const { prompt, inputDocx } = parseStartInput(ctx.start.content);
+      const raw = await runOfficeAgent(config, ctx.threadId, prompt, inputDocx);
+      const meta = schema.parse(JSON.parse(raw)) as T;
+      return { meta, childThread: null };
+    };
+}
+```
+
+`_systemPrompt` 为 writer 角色的 systemPrompt（空字符串），实际指令从 `ctx.start.content` 解析。
+
+### 配置
+

+
+## 三、`workflow-agent-docx-diff`
+
+`differ` 角色专用执行器。从 `ctx.steps` 读取 `WriterMeta`，调用本地 `docx-diff` CLI。
+
+### docx-diff 退出码约定
+
+| 退出码 | 含义 | runner 处理 |
+|---|---|---|
+| 0 | 无差异 | 正常，验证 diffDocx 存在 |
+| 1 | 有差异 | 正常（显式处理为成功），验证 diffDocx 存在 |
+| 2+ | 错误 | throw |
+
+runner 收到 `SpawnCliError { kind: "non_zero_exit", exitCode: 1 }` 时视为成功，验证文件后继续；`exitCode >= 2` 才 throw。
+
+### 执行流程
+
+```
+1. 从 ctx.steps 找到 writer 步骤，读取 WriterMeta
+2. 验证 mode === "edit"（否则 throw）
+3. diffDocx = join(dirname(writer.outputDocx), "diff.docx")
+4. const command = config.command ?? "docx-diff"
+5. spawnCli(command,
+     [writer.sourceDocx, writer.outputDocx, "--output", "docx", "--out-file", diffDocx],
+     { cwd: null, timeoutMs: null })
+   exit 0 或 1 → 验证 diffDocx 存在
+   exit 2+ → throw
+6. 返回 JSON.stringify({ sourceDocx, modifiedDocx: writer.outputDocx, diffDocx })
+```
+
+### AdapterFn 实现（直接实现，不经过 runtime.extract）
+
+```typescript
+export function createDocxDiffAgent(config: DocxDiffAgentConfig = { command: null }): AdapterFn {
+  return <T>(_prompt: string, schema: z.ZodType<T>) =>
+    async (ctx: ThreadContext, _runtime: WorkflowRuntime): Promise<RoleResult<T>> => {
+      const writerStep = ctx.steps.find(s => s.role === "writer");
+      if (!writerStep) throw new Error("differ: no writer step found");
+      const writerMeta = writerStep.meta as WriterMeta;
+      if (writerMeta.mode !== "edit")
+        throw new Error("differ: writer did not run in edit mode");
+      const raw = await runDocxDiff(config, writerMeta);
+      const meta = schema.parse(JSON.parse(raw)) as T;
+      return { meta, childThread: null };
+    };
+}
+```
+
+### 配置
+
+```typescript
+type DocxDiffAgentConfig = {
+  command: string | null;   // null → runner 内 resolve 为 "docx-diff"
+};
+```
+
+### packageDescriptor

+    properties: {
+      command: { anyOf: [{ type: "string" }, { type: "null" }], description: "Path to docx-diff CLI; null uses PATH." },
+    },
+    additionalProperties: false,
+  },
+};
+```

+# `uwf` — Stateless Workflow CLI
+
+> 将 workflow 引擎降维为无状态单步 CLI。Workflow 是纯数据（CAS 节点），执行是单步原子操作，agent 是可插拔外部命令。
+
+---
+
+## 1. CLI Design
+
+### 1.1 命令总览
+
+```
+# thread 组
+uwf thread start <workflow> -p <prompt>     # 创建 thread，不执行
+uwf thread step  <thread-id> [--agent]      # 单步执行
+uwf thread show  <thread-id>                # thread-id → head 查询
+uwf thread list  [--all]                    # 列出活跃 threads（--all 含已归档）
+uwf thread kill  <thread-id>                # 终结 thread，归档
+
+# workflow 组
+uwf workflow put   <file.yaml>              # 注册 workflow（YAML → CAS）
+uwf workflow show  <workflow-id>            # 查看 workflow 定义
+uwf workflow list                           # 列出已注册 workflows
+```
+
+两组对称，各 3-4 个子命令。CAS 操作交给 `json-cas` CLI，不在 `uwf` 中重复。
+
+### 1.2 `uwf thread start`
+
+```bash
+uwf thread start <workflow> -p "Fix the login bug described in issue #42"
+```
+
+- `<workflow>` — workflow 名或 CAS hash
+- `-p` — 用户 prompt（必填）
+
+**输出（JSON to stdout）：**
+
+```jsonc
+{
+  "workflow": "4KNM2PXR3B1QW",   // workflow CAS hash (XXH64, 13-char Crockford Base32)
+  "thread": "01J7K9M2XNPQR5VWBCDF8G3H4T"      // ULID
+}
+```
+
+**做的事：**
+1. 解析 workflow（名字查 registry → CAS hash）
+2. 生成 thread ULID
+3. 写 StartNode 到 CAS
+4. 在 threads.yaml 中记录链头 → StartNode hash
+5. 输出 JSON
+
+### 1.3 `uwf thread step`
+
+```bash
+uwf thread step 01J7K9M2XNPQR5VWBCDF8G3H4T
+uwf thread step 01J7K9M2XNPQR5VWBCDF8G3H4T --agent "bunx uwf-cursor"
+```
+
+**输出（JSON to stdout）：**
+
+```jsonc
+{
+  "workflow": "4KNM2PXR3B1QW",
+  "thread": "01J7K9M2XNPQR5VWBCDF8G3H4T",
+  "head": "8FWKR3TN5V1QA",       // 新链头 StepNode 的 CAS hash
+  "done": false                    // true = moderator 返回 END，thread 已归档
+}
+```
+
+`done: true` 时 head 仍然有值（最后一个 StepNode），但 thread 已从 threads.yaml 移除。
+对已结束或不存在的 thread 调用 step 会报错（非 active thread）。
+
+详细信息通过 `uwf thread show <thread-id>` 或 `json-cas get <head>` 查看。
+
+**做的事：**
+1. 读链头 → 当前 StepNode（或 StartNode）
+2. 收集 thread 历史（遍历链）
+3. 调 moderator：评估 JSONata conditions → 得到下一个 role（或 END）
+4. 若 END → 归档 thread，输出最后链头，退出
+5. 确定 agent command（`--agent` override > config.yaml per-workflow/role > config.yaml defaultAgent）
+6. 调用：`<agent-cmd> <thread-id> <role>`，捕获 stdout 得到新 StepNode hash
+7. 更新链头指针
+8. 再次调 moderator（基于新 StepNode）判断 done
+9. 输出 JSON
+
+### 1.4 `uwf thread show`
+
+```bash
+uwf thread show 01J7K9M2XNPQR5VWBCDF8G3H4T
+```
+
+**输出（JSON to stdout）：**
+
+```jsonc
+{
+  "workflow": "4KNM2PXR3B1QW",
+  "thread": "01J7K9M2XNPQR5VWBCDF8G3H4T",
+  "head": "8FWKR3TN5V1QA",
+  "done": false
+}
+```
+
+纯 thread-id → head 查询。详细内容用 `json-cas get <head>` 或 `json-cas walk <head>` 查看。
+
+### 1.5 Agent CLI 协议
+
+每个 agent 是一个命令，接受 thread-id 和 role 两个参数：
+
+```bash
+uwf-hermes <thread-id> <role>
+```
+
+**约定：**
+- `uwf step` 负责 moderator 决策，将 role 传给 agent CLI
+- agent-kit 根据 thread + role 从 CAS 读 goal / capabilities / procedure / output / meta
+- agent-kit 组装完整 prompt（role goal/capabilities/procedure/output + thread context + user prompt from StartNode）
+- agent 执行实际逻辑，agent-kit 负责 extract
+- agent 将 StepNode 写入 CAS（含 output、detail、agent、prev），但**不挪链头指针**
+- stdout 输出新 StepNode 的 CAS hash（纯文本，一行）
+- 所有配置从环境变量读（LLM model、API key、extractor config）
+- exit 0 = 成功，非 0 = 失败
+
+**stdout 输出：**
+
+```
+8FWKR3TN5V1QA
+```
+
+`uwf step` 拿到这个 hash 后更新链头指针、判断 done。
+
+---
+
+## 2. CAS 结构定义
+
+### 2.1 类型层级
+
+沿用 json-cas 的三层：bootstrap meta-schema → JSON Schema nodes → data nodes。
+
+下面所有 CAS 节点都遵循 `{ type: cas_ref, payload: T, timestamp: number }` 的标准格式。
+`cas_ref` 类型的字符串字段在 json-cas 中已内置支持，不需要额外的 `$ref` 包装。
+
+### 2.2 数据节点
+
+#### `Workflow`
+
+Roles 和 moderator 内联在 Workflow 中，只有 meta 独立为 CAS 节点（方便 json-cas 校验）。
+
+```yaml
+type: <workflow-schema-hash>
+payload:
+  name: "solve-issue"
+  description: "End-to-end issue resolution"
+  roles:
+    planner:
+      description: "Creates implementation plan"
+      goal: "You are a planning agent..."
+      capabilities: [planning, issue-analysis]
+      procedure: "Analyze the issue and create a plan."
+      output: "Output the plan summary."
+      meta: "5GWKR8TN1V3JA"    # cas_ref → JSON Schema 节点（json-cas 内置）
+    developer:
+      description: "Implements code changes"
+      goal: "You are a developer agent..."
+      capabilities: [file-edit, shell]
+      procedure: "Implement the plan."
+      output: "List all files changed."
+      meta: "8CNWT4KR6D1HV"    # cas_ref → JSON Schema 节点
+    reviewer:
+      description: "Reviews code changes"
+      goal: "You are a code reviewer..."
+      capabilities: [code-review]
+      procedure: "Review the implementation."
+      output: "Approve or reject with comments."
+      meta: "1VPBG9SM5E7WK"    # cas_ref → JSON Schema 节点
+  conditions:
+    needsClarification:
+      description: "Planner requests clarification from user"
+      expression: "$exists(steps[-1].output.needsClarification)"
+    notApproved:
+      description: "Reviewer rejected the implementation"
+      expression: "steps[-1].output.approved = false"
+  graph:
+    $START:
+      - role: "planner"
+        condition: null                  # 无条件（fallback）
+    planner:
+      - role: "developer"
+        condition: "needsClarification"
+      - role: "$END"
+        condition: null
+    developer:
+      - role: "reviewer"
+        condition: null
+    reviewer:
+      - role: "developer"
+        condition: "notApproved"
+      - role: "$END"
+        condition: null
+```
+
+- `roles` — 内联定义，每个 role 的 `meta` 是独立的 cas_ref（指向 json-cas 内置 JSON Schema 节点）
+- `conditions` — `Record<Name, JSONata>`，命名条件，方便画图描述
+- `graph` — `Record<Role | "$START", Transition[]>`，每个 Transition = `{ role, condition }`
+- `condition` 引用 conditions 中的 key，`null` = fallback
+- 按数组顺序求值，第一个匹配的 transition 胜出
+- 不含 agent binding — agent 配置在 `~/.uncaged/workflow/config.yaml` 中管理
+
+JSONata 表达式的求值上下文：
+
+```jsonc
+{
+  "start": {                          // StartNode 信息
+    "workflow": "4KNM2PXR3B1QW",
+    "prompt": "Fix the login bug..."
+  },
+  "steps": [                          // 所有已完成 steps，从旧到新
+    { "role": "planner", "output": { "phases": [...] }, "detail": "7BQST3VW9F2MA", "agent": "uwf-hermes" },
+    { "role": "developer", "output": { "filesChanged": ["src/auth.ts"], "summary": "Fixed redirect" }, "detail": "9KRVW3TN5F1QA", "agent": "uwf-cursor" },
+    { "role": "reviewer", "output": { "approved": false }, "detail": "2MXBG6PN4A8JR", "agent": "uwf-hermes" }
+  ]
+}
+```
+
+注：`output` 在上下文中会被自动展开为实际的 CAS 节点内容（而非 hash），方便 JSONata 表达式直接访问字段。
+
+#### `StartNode`（Thread 起点）
+
+```yaml
+type: <start-node-schema-hash>
+payload:
+  workflow: "4KNM2PXR3B1QW"        # cas_ref → Workflow
+  prompt: "Fix the login bug..."
+```
+
+- 没有 thread-id — thread-id 是索引层面的事，不进 CAS 内容
+- 没有 agent binding — 运行时从 config.yaml 解析
+
+#### `StepNode`（Thread 每一步）
+
+```yaml
+type: <step-node-schema-hash>
+payload:
+  start: "4TNVW8KR2B3MA"          # cas_ref → StartNode（每个 step 都引用）
+  prev: "2MXBG6PN4A8JR"           # cas_ref → 前一个 StepNode，第一步为 null
+  role: "developer"
+  output: "9KRVW3TN5F1QA"         # cas_ref → 结构化输出节点（符合 role 的 meta schema）
+  detail: "7BQST3VW9F2MA"         # cas_ref → 执行详情（content node / 子 workflow terminal StepNode / ...）
+  agent: "uwf-cursor"              # 实际使用的 agent 命令（纯字符串）
+```
+
+- `start` — 每个 StepNode 都直接引用 StartNode，方便随机访问
+- `prev` — 前一个 StepNode 的 cas_ref，第一步为 `null`（不指向 StartNode）
+- `output` — cas_ref，指向符合 role meta schema 的 CAS 节点，可用 json-cas 校验
+- `detail` — cas_ref，指向执行详情。可以是原始 agent 输出（content node），也可以是子 workflow thread 的 terminal StepNode（workflowAsAgent 场景）
+- `agent` — 纯字符串，不是 CAS 节点
+

+JSONata 求值上下文本质上是 thread 链表的线性化表达。StepNode payload 和上下文中的 step 共享大量字段，提取为公共类型。
+
+### 4.1 公共类型
+
+```typescript
+/** CAS hash — XXH64, 13-char Crockford Base32 */
+type CasRef = string;
+
+/** Thread ID — ULID, 26-char Crockford Base32 */
+type ThreadId = string;
+
+/** 一个 step 的核心数据，被 StepNode payload 和 JSONata 上下文共享 */
+type StepRecord = {
+  role: string;
+  output: CasRef;                    // cas_ref → 结构化输出节点（符合 role meta schema）
+  detail: CasRef;                    // cas_ref → 执行详情（content node / 子 workflow terminal StepNode）
+  agent: string;                     // 实际使用的 agent 命令（纯字符串）
+};
+```
+
+### 4.2 Workflow 定义
+
+```typescript
+type RoleDefinition = {
+  description: string;
+  goal: string;
+  capabilities: string[];
+  procedure: string;
+  output: string;
+  meta: CasRef;                      // cas_ref → json-cas 内置 JSON Schema 节点
+};
+
+type Transition = {
+  role: string;                      // 目标 role 名 或 "$END"
+  condition: string | null;          // 引用 conditions 中的 key，null = fallback
+};
+
+type ConditionDefinition = {
+  description: string;
+  expression: string;                           // JSONata expression
+};
+
+type WorkflowPayload = {
+  name: string;
+  description: string;
+  roles: Record<string, RoleDefinition>;
+  conditions: Record<string, ConditionDefinition>;
+  graph: Record<string, Transition[]>;          // Record<Role | "$START", Transition[]>
+};
+```
+
+### 4.3 Thread 节点
+
+```typescript
+type StartNodePayload = {
+  workflow: CasRef;                  // cas_ref → Workflow
+  prompt: string;
+};
+
+type StepNodePayload = StepRecord & {
+  start: CasRef;                     // cas_ref → StartNode（每个 step 都引用）
+  prev: CasRef | null;               // cas_ref → 前一个 StepNode，第一步为 null
+};
+```
+
+### 4.4 JSONata 求值上下文
+
+Thread 链表的线性化。`steps[n]` 的字段和 `StepRecord` 一致，但 `output` 被展开为实际内容。
+
+```typescript
+/** JSONata 上下文中的 step — output 被展开 */
+type StepContext = Omit<StepRecord, "output"> & {
+  output: unknown;                   // 展开后的 CAS 节点内容，非 hash
+};
+
+type ModeratorContext = {
+  start: StartNodePayload;
+  steps: StepContext[];              // 从旧到新
+};
+```
+
+### 4.5 CLI 输出
+
+```typescript
+/** uwf thread start */
+type StartOutput = {
+  workflow: CasRef;
+  thread: ThreadId;
+};
+
+/** uwf thread step / uwf thread show */
+type StepOutput = {
+  workflow: CasRef;
+  thread: ThreadId;
+  head: CasRef;
+  done: boolean;
+};
+
+/** uwf thread list */
+type ThreadListItem = {
+  thread: ThreadId;
+  workflow: CasRef;
+  head: CasRef;
+};
+```
+
+### 4.6 配置
+
+```typescript
+/** Alias types for config references */
+type AgentAlias = string;
+type ModelAlias = string;
+type ProviderAlias = string;
+type WorkflowName = string;
+type RoleName = string;
+type Scenario = string;              // e.g. "extract"
+
+type ProviderConfig = {
+  baseUrl: string;
+  apiKeyEnv: string;                 // env var name to read API key from
+};
+
+type ModelConfig = {
+  provider: ProviderAlias;
+  name: string;                      // e.g. "anthropic/claude-sonnet-4", "gpt-4o-mini"
+};
+
+type AgentConfig = {
+  command: string;
+  args: string[];
+};
+
+/** ~/.uncaged/workflow/config.yaml */
+type WorkflowConfig = {
+  providers: Record<ProviderAlias, ProviderConfig>;
+  models: Record<ModelAlias, ModelConfig>;
+  agents: Record<AgentAlias, AgentConfig>;
+  defaultAgent: AgentAlias;
+  agentOverrides: Record<WorkflowName, Record<RoleName, AgentAlias>> | null;
+  defaultModel: ModelAlias;
+  modelOverrides: Record<Scenario, ModelAlias> | null;
+};
+
+/** ~/.uncaged/workflow/threads.yaml */
+type ThreadsIndex = Record<ThreadId, CasRef>;
+//                         ^ thread-id  ^ head StepNode/StartNode hash
