From a1f77800d3e81ddd8a23de5ac744cf1276c188c3 Mon Sep 17 00:00:00 2001 From: Reiase Date: Sun, 18 Jan 2026 21:42:37 +0800 Subject: [PATCH 01/24] Update README and documentation to reflect changes in actor command structure and remove deprecated features - Updated README files to clarify the usage of the `pulsing actor` command, now requiring full class paths for actor types. - Enhanced documentation for starting actors, including examples for the new Router and worker classes. - Removed references to the deprecated `pulsing actor list` command, replacing it with `pulsing inspect` for actor system observation. - Updated various examples and guides to align with the new command structure and improve user understanding. --- README.md | 8 +- README.zh.md | 8 +- docs/actor-list-guide.md | 128 ------------ docs/actor-list-implementation.md | 254 ------------------------ docs/mkdocs.yml | 2 + docs/overrides/home.html | 6 +- docs/src/api_reference.md | 32 ++- docs/src/api_reference.zh.md | 32 ++- docs/src/examples/llm_inference.md | 4 +- docs/src/examples/llm_inference.zh.md | 4 +- docs/src/guide/operations.md | 20 +- docs/src/guide/operations.zh.md | 20 +- docs/src/guide/style.md | 69 +++++++ docs/src/guide/style.zh.md | 69 +++++++ docs/src/quickstart/llm_inference.md | 18 +- docs/src/quickstart/llm_inference.zh.md | 18 +- examples/bash/README.md | 87 ++------ examples/bash/demo_actor_list.sh | 155 --------------- examples/bash/demo_actor_list_remote.sh | 145 -------------- examples/inspect/demo_service.py | 22 +- python/pulsing/actor/helpers.py | 28 +-- python/pulsing/actors/__init__.py | 3 +- python/pulsing/actors/router.py | 119 ++++++++++- python/pulsing/cli/__main__.py | 16 +- test_actor_list_integration.py | 73 ------- test_actor_list_same_process.py | 61 ------ test_actor_system.py | 45 ----- 27 files changed, 424 insertions(+), 1022 deletions(-) delete mode 100644 docs/actor-list-guide.md delete mode 100644 docs/actor-list-implementation.md create mode 100644 docs/src/guide/style.md create mode 100644 docs/src/guide/style.zh.md delete mode 100755 examples/bash/demo_actor_list.sh delete mode 100644 examples/bash/demo_actor_list_remote.sh delete mode 100644 test_actor_list_integration.py delete mode 100644 test_actor_list_same_process.py delete mode 100644 test_actor_system.py diff --git a/README.md b/README.md index 27444117f..12367a7cb 100644 --- a/README.md +++ b/README.md @@ -10,9 +10,13 @@ **Lightweight distributed framework designed for high-performance AI applications.** 🚀 **Zero Dependencies** — Pure Rust + Tokio, no NATS/etcd/Redis + 🌐 **Auto Discovery** — Built-in Gossip protocol for cluster management + 🔀 **Location Transparent** — Same API for local and remote Actors + ⚡ **Streaming Ready** — Native support for LLM streaming responses + 🤖 **Agent Friendly** — Integrates with AutoGen, LangGraph out of the box ## 🚀 Get Started in 5 Minutes @@ -129,10 +133,10 @@ Out-of-the-box GPU cluster inference: ```bash # Start Router (OpenAI-compatible API) -pulsing actor router --addr 0.0.0.0:8000 --http_port 8080 --model_name my-llm +pulsing actor pulsing.actors.Router --addr 0.0.0.0:8000 --http_port 8080 --model_name my-llm # Start vLLM Worker (can have multiple) -pulsing actor vllm --model Qwen/Qwen2.5-0.5B --addr 0.0.0.0:8002 --seeds 127.0.0.1:8000 +pulsing actor pulsing.actors.VllmWorker --model Qwen/Qwen2.5-0.5B --addr 0.0.0.0:8002 --seeds 127.0.0.1:8000 # Test curl http://localhost:8080/v1/chat/completions \ diff --git a/README.zh.md b/README.zh.md index daab762e0..634427498 100644 --- a/README.zh.md +++ b/README.zh.md @@ -10,9 +10,13 @@ **轻量级分布式框架，专为高性能 AI 应用设计。** 🚀 **零外部依赖** — 纯 Rust + Tokio，无需 NATS/etcd/Redis + 🌐 **自动发现** — 内置 Gossip 协议管理集群 + 🔀 **位置透明** — 本地和远程 Actor 使用相同 API + ⚡ **流式支持** — 原生支持 LLM 流式响应 + 🤖 **Agent 友好** — 开箱即用集成 AutoGen、LangGraph ## 🚀 5分钟快速体验 @@ -129,10 +133,10 @@ async with runtime(addr="0.0.0.0:8002", seeds=["node1:8001"]): ```bash # 启动 Router（OpenAI 兼容 API） -pulsing actor router --addr 0.0.0.0:8000 --http_port 8080 --model_name my-llm +pulsing actor pulsing.actors.Router --addr 0.0.0.0:8000 --http_port 8080 --model_name my-llm # 启动 vLLM Worker（可多个） -pulsing actor vllm --model Qwen/Qwen2.5-0.5B --addr 0.0.0.0:8002 --seeds 127.0.0.1:8000 +pulsing actor pulsing.actors.VllmWorker --model Qwen/Qwen2.5-0.5B --addr 0.0.0.0:8002 --seeds 127.0.0.1:8000 # 测试 curl http://localhost:8080/v1/chat/completions \ diff --git a/docs/actor-list-guide.md b/docs/actor-list-guide.md deleted file mode 100644 index 9817b4a4d..000000000 --- a/docs/actor-list-guide.md +++ /dev/null @@ -1,128 +0,0 @@ -# Actor List 命令使用指南 -

+# Terminology & Style Guide
+
+This page defines terminology and style conventions for Pulsing documentation and code to ensure consistency.
+
+## Core Terminology
+
+| Term | Usage | Description |
+|------|-------|-------------|
+| `ActorSystem` | Code symbol | Rust/Python class name, use in code references |
+| actor system | Conceptual | General description, lowercase |
+| `Actor` | Code symbol | Base class name |
+| actor | Conceptual | General description |
+| `ActorRef` | Code symbol | Low-level actor reference |
+| `ActorProxy` | Code symbol | High-level proxy returned by `@remote` decorator |
+
+## Component Naming
+
+| Component | CLI Actor Class Path | Description |
+|-----------|---------------------|-------------|
+| Router | `pulsing.actors.Router` | OpenAI-compatible HTTP router |
+| TransformersWorker | `pulsing.actors.TransformersWorker` | Transformers inference worker |
+| VllmWorker | `pulsing.actors.VllmWorker` | vLLM inference worker |
+
+**Note**: When documentation mentions "Router", it typically refers to the HTTP routing component for LLM inference services. Example code requiring task dispatch logic should use names like `Dispatcher` to avoid confusion.
+
+## CLI Command Format
+
+### Starting Actors
+
+```bash
+pulsing actor  [options]
+
+# Examples
+pulsing actor pulsing.actors.Router --http_port 8080 --model_name my-llm
+pulsing actor pulsing.actors.TransformersWorker --model_name gpt2 --device cpu
+```
+
+### Inspect Commands (Observer Mode)
+
+`pulsing inspect` uses a subcommand structure:
+
+```bash
+# Cluster status
+pulsing inspect cluster --seeds 

+
+# Actor distribution
+pulsing inspect actors --seeds 
 [--top N] [--filter ...]
+pulsing inspect actors --endpoint 
 [--detailed]
+
+# Metrics
+pulsing inspect metrics --seeds 
 [--raw]
+
+# Live watch
+pulsing inspect watch --seeds 
 [--interval ...] [--kind ...]
+```
+
+**Removed**: `pulsing actor list` → Use `pulsing inspect actors` instead
+
+## Code Style
+
+- **Python**: Follow PEP 8, prefer type annotations
+- **Rust**: Use `cargo fmt` and `cargo clippy`
+- **Documentation**: Bilingual (`.zh.md` suffix for Chinese)
+
+## Documentation References
+
+- Use backticks for code symbols: `` `ActorSystem` ``
+- Use code blocks for commands
+- Use backticks for file paths: `` `python/pulsing/actor/` ``

+# 术语与风格约定
+
+本页定义 Pulsing 文档和代码中的术语与风格规范，确保一致性。
+
+## 核心术语
+
+| 术语 | 用法 | 说明 |
+|------|------|------|
+| `ActorSystem` | 代码符号 | Rust/Python 类名，用于代码引用 |
+| actor system | 概念描述 | 一般性描述时使用小写 |
+| `Actor` | 代码符号 | 基类名 |
+| actor | 概念描述 | 一般性描述 |
+| `ActorRef` | 代码符号 | 底层 actor 引用 |
+| `ActorProxy` | 代码符号 | `@remote` 装饰器返回的高级代理 |
+
+## 组件命名
+
+| 组件 | CLI actor 类路径 | 说明 |
+|------|------------------|------|
+| Router | `pulsing.actors.Router` | OpenAI 兼容 HTTP 路由 |
+| TransformersWorker | `pulsing.actors.TransformersWorker` | Transformers 推理 Worker |
+| VllmWorker | `pulsing.actors.VllmWorker` | vLLM 推理 Worker |
+
+**注意**：文档中提到"Router"时，通常指 LLM 推理服务的 HTTP 路由组件。示例代码中若需要任务分发逻辑，应使用 `Dispatcher` 等名称以避免混淆。
+
+## CLI 命令格式
+
+### 启动 Actor
+
+```bash
+pulsing actor <完整类路径> [选项]
+
+# 示例
+pulsing actor pulsing.actors.Router --http_port 8080 --model_name my-llm
+pulsing actor pulsing.actors.TransformersWorker --model_name gpt2 --device cpu
+```
+
+### 检查命令（观察者模式）
+
+`pulsing inspect` 使用子命令结构：
+
+```bash
+# 集群状态
+pulsing inspect cluster --seeds <地址>
+
+# Actor 分布
+pulsing inspect actors --seeds <地址> [--top N] [--filter ...]
+pulsing inspect actors --endpoint <地址> [--detailed]
+
+# 指标
+pulsing inspect metrics --seeds <地址> [--raw]
+
+# 实时监视
+pulsing inspect watch --seeds <地址> [--interval ...] [--kind ...]
+```
+
+**已移除**：`pulsing actor list` → 请使用 `pulsing inspect actors`
+
+## 代码风格
+
+- **Python**：遵循 PEP 8，优先使用类型注解
+- **Rust**：使用 `cargo fmt` 和 `cargo clippy`
+- **文档**：中英双语（`.zh.md` 为中文版）
+
+## 文档引用
+
+- 代码符号使用反引号：`` `ActorSystem` ``
+- 命令使用代码块
+- 文件路径使用反引号：`` `python/pulsing/actor/` ``

-
-Total: 3 actor(s)
-
-...
-```
-
-**重要说明：**
-
-`pulsing actor list` 是设计用于在**运行中的应用进程内**调用的管理功能，而不是独立的命令行工具。这是因为：
-
-1. Actor system 是进程本地的，需要在同一进程中才能访问
-2. 这种设计更适合集成到应用的管理接口中
-3. 对于外部查看远程集群，应使用 `pulsing inspect --seeds 
`
-
-**在应用中集成：**
-
-```python
-from pulsing.actor import init, get_system
-from pulsing.cli.actor_list import list_actors_impl
-
-await init()
-# ... 创建 actors ...
-
-# 在管理端点或 REPL 中调用
-await list_actors_impl(all_actors=False, output_format='table')
-```
+更多 CLI 用法参见 [CLI 命令文档](../../docs/src/guide/operations.zh.md)。

Subject: [PATCH 02/24] Add pulsing examples for multi-agent workflows and
 chaos-proof functionality

- Introduced `pulsing_pingpong.py` demonstrating a simple ping-pong interaction using the @remote decorator.
- Added `pulsing_research.py` showcasing a multi-agent research workflow with Researcher, Analyst, and Reporter agents.
- Created `chaos_proof.py` to illustrate actor resilience with automatic restarts on failure, simulating task completion despite crashes.
- Implemented `function_to_fleet.py` to demonstrate scaling functions into a fleet of workers for improved throughput.
- Updated README with new examples and usage instructions for enhanced clarity and user guidance.

+## ⚡ 进阶示例
+
+### 示例 3: Function → Fleet（横向扩展）
+
+**一行代码把函数变成可横向扩展的服务**——同一份代码，workers 从 1→N，吞吐线性提升：
+
+```bash
+# 8 个 worker 处理 200 个任务
+python examples/quickstart/function_to_fleet.py
+
+# 调整 worker 数量
+WORKERS=16 ITEMS=500 python examples/quickstart/function_to_fleet.py
+```
+
+输出：
+```
+==================================================
+⚡ Function → Fleet Result
+==================================================
+   Workers:     8
+   Tasks:       200
+   Duration:    0.52s
+   Throughput:  384.6 qps
+==================================================
+✅ Same code, more workers = higher throughput
+==================================================
+```
+
+**核心代码**（仅 27 行）：
+```python
+@remote
+class Worker:
+    async def run(self, x: int) -> int:
+        await asyncio.sleep(0.02)  # simulate I/O
+        return x * x
+
+async with runtime():
+    ws = [await Worker.spawn(name=f"w{i}") for i in range(n)]
+    res = await asyncio.gather(*(ws[i % n].run(i) for i in range(m)))
+```
+
+### 示例 4: Chaos-proof（故障自愈）
+
+**Actor 崩溃后自动重启**——30% 崩溃率下，任务仍然全部完成：
+
+```bash
+python examples/quickstart/chaos_proof.py
+```
+
+输出：
+```
+==================================================
+🛡️  Chaos-proof Result
+==================================================
+   Total tasks:   50
+   Succeeded:     50
+   Retries:       23
+   Crash rate:    30%
+==================================================
+✅ All succeeded! Actor auto-restarted on crash.
+==================================================
+```
+
+**核心代码**：
+```python
+@remote(restart_policy="on-failure", max_restarts=50)
+class FlakyWorker:
+    def work(self, x: int) -> int:
+        if random.random() < 0.3:  # 30% 概率崩溃
+            raise RuntimeError("boom")
+        return x + 1
+```
+
+**亮点**：30% 崩溃率，框架自动重启 Actor，调用方简单重试，最终 100% 完成。
+

Subject: [PATCH 03/24] Refactor actor spawning to improve clarity and
 consistency

- Updated actor spawning calls across multiple files to use named parameters for better readability, ensuring the actor name is explicitly defined.
- Adjusted print statements in various examples to enhance formatting consistency.
- Enhanced the `spawn` method in the actor system to support anonymous actors and custom options, improving flexibility in actor management.
- Refactored tests to align with the new actor spawning structure, ensuring comprehensive coverage and reliability in functionality.

Subject: [PATCH 04/24] Add LLMs binding documentation and update API
 references

- Introduced a new documentation file `llms.binding.md` detailing the Pulsing API reference for LLMs, including Python interface examples for Actor System and queue operations.
- Updated existing API reference documentation (`api_reference.md` and `api_reference.zh.md`) to reflect the new `pul.actor_system` usage and provide clearer examples.
- Revised example scripts for distributed counter and ping-pong interactions to align with the new API structure, enhancing clarity and usability.
- Refactored queue documentation to standardize the usage of `system.queue.write` and `system.queue.read` methods, improving consistency across examples and guides.
- Enhanced the README files to include updated usage instructions and examples for the new queue API, ensuring comprehensive user guidance.

+
+## Overview
+
+`Pulsing`是一款分布式系统通信框架，可以作为任意分布式系统的通信骨架，以方便快速搭建分布式系统和应用。
+
+## Python 接口
+
+### Actor System风格接口
+

+) -> ActorRef
+

+await writer.put({"user_id": "u1", "data": "hello"})
+

+```
+
+### Ray风格异步接口
+
+```python
+import pulsing as pul
+

+
+# 发送消息并等待响应

+result = await counter.incr()  # 返回 ActorProxy，直接调用方法
+
+# 使用方式2：通过 resolve 解析已有 actor
+proxy = await Counter.resolve("counter")
+result = await proxy.incr()
+
+```
+
+### Ray风格兼容接口
+
+```python
+from pulsing.compat import ray
+
+# 初始化（同步接口，内部使用异步）
+ray.init(
+    address: str | None = None,
+    *,
+    ignore_reinit_error: bool = False,

+    def __init__(self, ...): ...
+    def method(self, ...): ...
+
+# 创建 Actor（同步接口）
+actor_handle = MyActor.remote(...) -> _ActorHandle
+
+# 调用方法（返回 ObjectRef）
+result_ref = actor_handle.method.remote(...) -> ObjectRef
+
+# 获取结果（同步接口）
+result = ray.get(result_ref, timeout: float | None = None) -> Any
+
+# 关闭系统
+ray.shutdown() -> None

Subject: [PATCH 05/24] Refactor actor system initialization to use
 pul.actor_system

- Replaced instances of create_actor_system with pul.actor_system across multiple benchmark and test files for consistency.
- Updated actor system configuration to utilize named parameters for address and seed nodes, enhancing clarity in system setup.
- Improved documentation and test cases to reflect the new actor system initialization method, ensuring comprehensive coverage and usability.

Subject: [PATCH 06/24] Add new API methods and enhance documentation in
 llms.binding.md

- Introduced `ray.shutdown()` to close the system gracefully.
- Added `ray.is_initialized()` to check if the system is initialized.
- Updated `ray.get()` to support both single and list ObjectRefs for result retrieval.
- Introduced `ray.put()` for wrapping values as ObjectRefs for API compatibility.
- Added `ray.wait()` to wait for multiple ObjectRefs to complete, enhancing functionality and usability.

Subject: [PATCH 07/24] Enhance ActorClass API and add comprehensive tests

- Added a `public` parameter to the `ActorClass` methods for actor visibility control.
- Updated method signatures and documentation to reflect the new `public` argument.
- Introduced new test files for API coverage, including tests for actor system creation, spawning, and resolving.
- Created tests for both Ray-compatible and Ray-like APIs, ensuring robust functionality and compatibility.
- Added fixtures and comprehensive test cases to validate actor behavior and interactions.

 ```
+
+### Actor 行为
+
+#### 基础 Actor（使用 `receive` 方法）
+
+```python
+from pulsing.actor import Actor
+
+class EchoActor(Actor):
+    """receive 方法 - 同步或异步均可，框架自动检测"""
+    
+    # 方式1：同步方法
+    def receive(self, msg):
+        return msg
+    
+    # 方式2：异步方法（需要 await 时使用）
+    async def receive(self, msg):
+        result = await some_async_operation()
+        return result
+
+class FireAndForget(Actor):
+    """无返回值（适合 tell 调用）"""
+    def receive(self, msg):
+        print(f"Received: {msg}")
+        # 无返回值
+```
+
+**注意：** `receive` 方法可以是 `def` 或 `async def`，Pulsing 会自动检测并正确处理。
+只有当方法内部需要 `await` 其他协程时，才需要使用 `async def`。
+
+#### @pul.remote 装饰器（推荐）
+
+```python
+import pulsing as pul
+
+@pul.remote
+class Counter:
+    def __init__(self, init=0):
+        self.value = init
+    
+    # 同步方法 - 阻塞处理，请求按顺序执行
+    # 适合：快速计算、状态修改
+    def incr(self):
+        self.value += 1
+        return self.value
+    
+    # 异步方法 - 非阻塞，可并发处理多个请求
+    # 适合：IO 密集型操作（网络请求、数据库查询）
+    async def fetch_and_add(self, url):
+        data = await http_get(url)  # 等待期间可处理其他请求
+        self.value += data
+        return self.value
+    
+    # 无返回值方法 - 适合 tell() 调用
+    def reset(self):
+        self.value = 0
+
+# 同步 vs 异步方法的并发行为：
+# - def method():     阻塞 Actor，请求排队顺序执行
+# - async def method(): 非阻塞，await 期间可处理其他请求（并发）
+
+# 使用
+counter = await Counter.spawn(name="counter")
+result = await counter.incr()      # ask 模式，等待返回
+await counter.reset()              # 无返回值，但仍等待完成
+```
+
+#### 消息传递模式
+
+```python
+# ask - 发送消息并等待响应
+response = await actorref.ask({"action": "get"})
+
+# tell - 发送消息，不等待响应（fire-and-forget）
+await actorref.tell({"action": "log", "data": "hello"})
+```
+
+#### Actor 生命周期
+
+```python
+from pulsing.actor import Actor, ActorId
+
+class MyActor(Actor):
+    def on_start(self, actor_id: ActorId):
+        """Actor 启动时调用"""
+        print(f"Started: {actor_id}")
+    
+    def on_stop(self):
+        """Actor 停止时调用"""
+        print("Stopping...")
+    
+    def metadata(self) -> dict[str, str]:
+        """返回 Actor 元数据（用于诊断）"""
+        return {"type": "worker", "version": "1.0"}
+    
+    async def receive(self, msg):
+        return msg
+```
+
+#### 监督与重启策略
+
+```python
+@pul.remote(
+    restart_policy="on_failure",  # "never" | "on_failure" | "always"
+    max_restarts=3,               # 最大重启次数
+    min_backoff=0.1,              # 最小退避时间（秒）
+    max_backoff=30.0,             # 最大退避时间（秒）
+)
+class ResilientWorker:
+    def process(self, data):
+        # 如果抛出异常，Actor 会自动重启
+        return heavy_computation(data)
+```
+
+#### 流式响应
+
+```python
+@pul.remote
+class StreamingService:
+    # 直接返回 generator，Pulsing 自动处理为流式响应
+    async def generate_stream(self, n):
+        for i in range(n):
+            yield f"chunk_{i}"
+    
+    # 同步 generator 也支持
+    def sync_stream(self, n):
+        for i in range(n):
+            yield f"item_{i}"
+
+# 使用
+service = await StreamingService.spawn()
+
+# 客户端消费流
+async for chunk in service.generate_stream(10):
+    print(chunk)  # chunk_0, chunk_1, ...
+```
+
+**注意：** 对于 `@pul.remote` 类，直接返回 generator（同步或异步）即可，Pulsing 会自动检测并按流式响应处理。

Subject: [PATCH 09/24] Add generator support to PyActorResponse for streaming
 values

- Introduced a new `Generator` variant in `PyActorResponse` to handle both synchronous and asynchronous Python generators.
- Implemented logic to iterate over generators in the `Actor` trait, utilizing channels for streaming values.
- Enhanced error handling for generator iteration, including checks for `StopIteration` and `StopAsyncIteration`.
- Updated the actor's response handling to accommodate the new generator functionality, improving the API's versatility.

Subject: [PATCH 10/24] Implement synchronous and asynchronous generator
 support in Actor API

- Added `_SyncGeneratorStreamReader` to handle synchronous generator responses in the Actor framework.
- Enhanced `_MethodCaller` to recognize stream messages and return appropriate stream readers.
- Introduced `_handle_generator_result` method in `_WrappedActor` to manage generator results and provide streaming responses.
- Removed outdated test files and added new tests for actor behavior, including comprehensive coverage for synchronous and asynchronous methods, message passing, and actor lifecycle management.
- Updated documentation to reflect changes in actor behavior and streaming capabilities.

Subject: [PATCH 11/24] Refactor Actor classes to remove dependency on Actor
 base class

- Converted WorkerActor, DispatcherActor, CacheActor, and EchoActor to standalone classes, eliminating the need for the Actor base class.
- Updated message handling to use dictionaries instead of Message objects for improved simplicity and clarity.
- Enhanced the receive methods to support action-based message processing, allowing for more flexible interactions.
- Adjusted example scripts to reflect the new class structures and message patterns, ensuring consistency across the codebase.

Subject: [PATCH 12/24] Update documentation and examples to reflect changes in
 actor resolution and API usage

- Removed references to `resolve()` in favor of `ClassName.resolve()` for clarity and consistency across documentation.
- Updated example scripts to demonstrate the new actor resolution method, ensuring users can easily find and interact with existing actors.
- Enhanced README and guide sections to provide clearer instructions on using the `@remote` decorator and actor spawning.
- Adjusted code snippets to reflect the latest API changes, improving overall usability and understanding of the Pulsing framework.

 ### ActorRef
 
-Low-level reference to an actor (local or remote). Usually not used directly; prefer `ActorProxy`.

-High-level proxy wrapper for actors, returned by `@remote` decorator's `spawn()` and `resolve()`.
-**Recommended: use ActorProxy to call methods directly**, no need to manually construct `Message`.
+High-level proxy for `@remote` classes. Call methods directly.

+    # Call methods directly:
     # result = await proxy.my_method(arg1, arg2)
 ```
 
-**ActorProxy vs ActorRef comparison**:
-
-| Scenario | Recommendation |
-|----------|----------------|
-| Call `@remote` class methods | `ActorProxy`: `await proxy.method()` |
-| Need low-level ask/tell | `ActorRef`: `await proxy.ref.ask(msg)` |
-| Need actor_id | `ActorRef`: `proxy.ref.actor_id` |
-
 ## Decorators
 
-### @remote
+### @remote / @pul.remote
 
-Convert a class into an Actor automatically.
+Convert a class into a distributed Actor.
 
 ```python
-from pulsing.actor import init, shutdown, remote
+import pulsing as pul
 
-@remote
-class MyActor:
-    def __init__(self, value: int):
-        self.value = value
+@pul.remote
+class Counter:
+    def __init__(self, init_value: int = 0):
+        self.value = init_value
 
-    def get(self) -> int:
+    # Sync method - sequential execution
+    def incr(self) -> int:
+        self.value += 1
         return self.value
 
-    async def process(self, data: str) -> dict:
-        return {"result": data.upper()}
-
-async def main():
-    await init()
-    actor = await MyActor.spawn(value=10)
-    print(await actor.get())  # 10
-    await shutdown()
-```
-
-#### Supervision (actor-level restarts)
+    # Async method - concurrent execution during await
+    async def fetch_and_add(self, url: str) -> int:
+        data = await http_get(url)
+        self.value += data
+        return self.value
 
-`@remote` supports **actor-level restarts** via optional parameters:
+    # Generator - automatic streaming
+    async def stream(self):
+        for i in range(10):
+            yield {"count": i}
 
-- `restart_policy`: `"never"` (default), `"always"`, `"on-failure"`
-- `max_restarts`: maximum number of restarts (default: `3`)
-- `min_backoff` / `max_backoff`: backoff bounds in seconds
+# Create actor
+counter = await Counter.spawn(name="counter")
 
-Example:
+# Call methods directly
+result = await counter.incr()
 
-```python
-from pulsing.actor import remote
+# Streaming
+async for chunk in counter.stream():
+    print(chunk)
 
-@remote(restart_policy="on-failure", max_restarts=5, min_backoff=0.2, max_backoff=10.0)
-class Worker:
-    def work(self, x: int) -> int:
-        return 100 // x
+# Resolve existing actor
+proxy = await Counter.resolve("counter")
 ```
 
-Notes:
+**Supervision parameters:**
 
-- This is **not** a supervision tree.
-- Restarts do **not** imply exactly-once semantics; design idempotent handlers.
-
-## Helpers
+```python
+@pul.remote(
+    restart_policy="on_failure",  # "never" | "on_failure" | "always"
+    max_restarts=3,
+    min_backoff=0.1,
+    max_backoff=30.0,
+)
+class ResilientWorker:
+    def work(self, data): ...
+```
 
-### ask_with_timeout
+## Base Actor
 
-Convenience wrapper around `ActorRef.ask()` with timeout support:
+For low-level control, inherit from Actor base class.
 
 ```python
-from pulsing.actor import ask_with_timeout
-
-result = await ask_with_timeout(ref, {"op": "compute"}, timeout=10.0)
-```
-
+class MyActor:
+    def __init__(self):
+        self.value = 0
 
-After decoration, the class provides:
+    def on_start(self, actor_id):
+        """Called when actor starts."""
+        print(f"Started: {actor_id}")
 
-- `spawn(**kwargs) -> ActorProxy`: Create actor and return proxy (uses global system from `init()`)
-- `local(system, **kwargs) -> ActorProxy`: Create actor on specified system
-- `resolve(name) -> ActorProxy`: Resolve an existing actor by name
+    async def receive(self, msg):
+        """Handle incoming messages."""
+        if msg.get("action") == "add":

+            return {"value": self.value}
+        return {"error": "unknown action"}
 
-**Recommended**: Use the returned `ActorProxy` to call methods directly; use `proxy.ref` for low-level `ask/tell`
+# Spawn
+system = await pul.actor_system()
+actor = await system.spawn(MyActor(), name="my_actor")
 
-## Functions
+# Communicate via ask/tell
+response = await actor.ask({"action": "add", "n": 10})
+```
 
-### pul.actor_system (Recommended)
+## Queue API
 
-Create a new Actor System instance with simple parameters.
+Distributed queue for data pipelines.
 
 ```python
-import pulsing as pul
-
-system = await pul.actor_system(
-    addr: str | None = None,      # Bind address, None for standalone
-    *,
-    seeds: list[str] | None = None,  # Seed nodes for cluster
-    passphrase: str | None = None,   # TLS passphrase
-) -> ActorSystem
+# Write

+await writer.flush()
+
+# Read
+reader = await system.queue.read("my_queue")
+records = await reader.get(limit=100)
 ```
 
-**Example:**
+## Ray Compatibility
 
-```python
-# Standalone mode
-system = await pul.actor_system()
+Drop-in replacement for Ray.
 
-# Cluster mode

 ```
 
-**ActorProxy vs ActorRef 对比**：
-
-| 场景 | 推荐 |
-|------|------|
-| 调用 `@remote` 类的方法 | `ActorProxy`：`await proxy.method()` |
-| 需要底层 ask/tell | `ActorRef`：`await proxy.ref.ask(msg)` |
-| 需要 actor_id | `ActorRef`：`proxy.ref.actor_id` |
-
 ## 装饰器
 
-### @remote
+### @remote / @pul.remote
 
-自动将类转换为 Actor。
+将类转换为分布式 Actor。

-`@remote` 支持通过可选参数配置 **actor 级别重启**：
+    # Generator - 自动流式传输
+    async def stream(self):
+        for i in range(10):
+            yield {"count": i}

-- `min_backoff` / `max_backoff`：退避时间下限/上限（单位秒）
+# 创建 actor
+counter = await Counter.spawn(name="counter")
 
-示例：
+# 直接调用方法

 ```
 
-说明：
+**监督参数：**
 
-- 这**不是** supervision tree。
-- 重启也**不等于** exactly-once；业务逻辑需要幂等与去重。

-### ask_with_timeout
+## 基础 Actor
 
-为 `ActorRef.ask()` 提供一个带超时的便捷封装：
+需要底层控制时，可使用基础 Actor 类。
 
 ```python
-from pulsing.actor import ask_with_timeout
-
-result = await ask_with_timeout(ref, {"op": "compute"}, timeout=10.0)
-```
-
+class MyActor:

+        print(f"Started: {actor_id}")
 
-- `spawn(**kwargs) -> ActorProxy`: 创建 actor 并返回代理（使用 `init()` 初始化的全局系统）
-- `local(system, **kwargs) -> ActorProxy`: 在指定 system 上创建 actor

+            return {"value": self.value}
+        return {"error": "unknown action"}
 
-**推荐**：直接使用返回的 `ActorProxy` 调用方法；如需底层 `ask/tell`，使用 `proxy.ref`
+# 生成

+actor = await system.spawn(MyActor(), name="my_actor")
 
-## 函数
+# 通过 ask/tell 通信

 ```python
-import pulsing as pul
-

-    *,
-    seeds: list[str] | None = None,  # 集群种子节点

+await writer.flush()
+
+# 读取
+reader = await system.queue.read("my_queue")

 ```
 
-**示例：**
+## Ray 兼容
 
-```python

 Complete API documentation for Pulsing Actor Framework.
 
+## Contract & Semantics (Derived from `llms.binding.md`)
+
+This section is the **user-facing contract** for Pulsing's Python API. It is **derived from** the repository document **`llms.binding.md`**.
+
+- **Source of truth**: `llms.binding.md` is the canonical contract.
+- **This page**: API reference + explicit semantics (concurrency, errors, trust boundaries).
+- **If there's a mismatch**: treat `llms.binding.md` as authoritative; please open an issue/PR to sync docs.
+
+### Concurrency model for `@pulsing.remote`
+
+For a `@pulsing.remote` class, method calls are translated into actor messages.
+
+- **Sync method (`def method`)**
+  - Executed **serially** (one request at a time) in the actor.
+  - Recommended for fast CPU work and state mutation.
+- **Async method (`async def method`)**
+  - The call uses **stream-backed execution** and is scheduled as a background task on the actor side.
+  - While the method is awaiting, the actor can continue receiving other messages (**non-blocking** behavior).
+  - You can either:
+    - `await proxy.async_method(...)` to get the final value, or
+    - `async for chunk in proxy.async_method(...): ...` to consume streamed yields.
+- **Generators (sync/async)**
+  - Returning a generator (sync or async) is treated as a **streaming response**.
+
+### Streaming & cancellation
+
+- Streaming is implemented via Pulsing stream messages; cancellation is **best-effort**.
+- If a caller cancels the local await/iteration, the remote side may or may not stop immediately, depending on transport-level cancellation propagation.
+
+### `ask` vs `tell`
+
+- **`ask(msg)`**: request/response. Returns a value (or raises).
+- **`tell(msg)`**: fire-and-forget. No response is awaited.
+
+### Error model (current behavior)
+
+- Actor-side exceptions are transported back and typically raised as **`RuntimeError(str(e))`** on the caller side.
+- Timeout helpers (where used) raise **`asyncio.TimeoutError`**.
+
+Note: error *type information and remote stack traces* are not guaranteed to be preserved.
+
+### Trust boundary & security notes
+
+- **Pickle-based payloads (Python ↔ Python)**:
+  - Python-to-Python payloads are transported as **pickle** by default for convenience.
+  - **Risk**: unpickling untrusted data can lead to arbitrary code execution (RCE).
+  - **Guideline**: only use pickle payloads inside a **trusted network / trusted cluster** boundary.
+- **Transport security (TLS)**:
+  - For production deployments, always enable TLS and treat the cluster as an authenticated trust boundary.
+
+### Queue semantics (distributed queue)
+
+- **Bucketing**:
+  - Writer uses `bucket_column` + `num_buckets` to partition records into buckets.
+  - Readers must use a consistent `num_buckets` (and backend) with writers.
+- **Ownership**:
+  - Bucket ownership is computed by hashing over live cluster members; requests may be redirected to the owning node.
+- **Backends**:
+  - Default backend is in-memory; persistence depends on the selected backend.
+

 Pulsing Actor 框架的完整 API 文档。
 
+## 契约与语义（由 `llms.binding.md` 派生）
+
+本节是 Pulsing Python API 的**面向用户契约**，内容**派生自**仓库根目录的 **`llms.binding.md`**。
+
+- **权威来源**：`llms.binding.md` 是对外契约源文件。
+- **本文档**：API 参考 + 显式语义声明（并发、错误、信任边界）。
+- **若两者不一致**：以 `llms.binding.md` 为准，并请提 Issue/PR 同步。
+
+### `@pulsing.remote` 的并发语义
+
+对 `@pulsing.remote` 类，方法调用会被翻译为 actor 消息并在 actor 内执行。
+
+- **同步方法（`def method`）**
+  - 在 actor 内**串行执行**（一次处理一个请求）。
+  - 适合：快速计算、状态修改。
+- **异步方法（`async def method`）**
+  - 调用走**基于流（stream）的执行路径**，在 actor 侧以后台任务调度。
+  - 当方法处于 `await` 等待期间，actor 仍可继续处理其他消息（即“非阻塞 actor”语义）。
+  - 你既可以：
+    - `await proxy.async_method(...)` 获取最终返回值；也可以
+    - `async for chunk in proxy.async_method(...): ...` 消费中间 `yield`。
+- **生成器（同步/异步）**
+  - 返回 generator（sync/async）会被当作**流式响应**。
+
+### 流式与取消（cancellation）
+
+- 流式响应通过 Pulsing stream message 实现；取消传播属于 **best-effort**。
+- 调用方取消本地 `await/async for` 时，远端是否立即停止取决于传输层取消传播。
+
+### `ask` 与 `tell`
+
+- **`ask(msg)`**：请求-响应，返回值或抛异常。
+- **`tell(msg)`**：fire-and-forget，不等待返回。
+
+### 错误模型（当前行为）
+
+- actor 内抛出的异常通常会在调用方表现为 **`RuntimeError(str(e))`**。
+- 若使用超时封装（如 `asyncio.wait_for`），超时会抛 **`asyncio.TimeoutError`**。
+
+注意：错误类型信息与远端堆栈不保证完整保留。
+
+### 信任边界与安全声明
+
+- **Python ↔ Python 默认使用 Pickle**：
+  - 为了易用性，Python↔Python 对象载荷默认使用 **pickle**。
+  - **风险**：对不可信数据 unpickle 可能导致任意代码执行（RCE）。
+  - **建议**：仅在**可信网络/可信集群边界**内使用。
+- **传输层安全（TLS）**：
+  - 生产环境建议启用 TLS/mTLS，并把集群内部通信视为经过认证的信任边界。
+
+### 队列语义（Distributed Queue）
+
+- **分桶**：
+  - 写端使用 `bucket_column` + `num_buckets` 决定 record 落到哪个 bucket。
+  - 读端必须与写端保持一致的 `num_buckets`（以及 backend）。
+- **归属（owner）**：
+  - bucket 的 owner 基于集群成员一致性哈希计算；请求可能被重定向到 owner 节点。
+- **后端**：
+  - 默认内存后端；是否持久化取决于 backend。
+

+// =============================================================================
+// Core Trait: Spawn + Resolve (Primary API)
+// =============================================================================
+
+/// Core API for spawning and resolving actors.
+///
+/// This trait defines the primary interface for creating and locating actors.
+/// It is automatically implemented for `Arc` and re-exported in prelude.
+///
+/// # Spawn Methods
+/// - [`spawn`](Self::spawn) - Spawn an actor with a local name
+/// - [`spawn_with_options`](Self::spawn_with_options) - Spawn with custom options
+/// - [`spawn_named`](Self::spawn_named) - Spawn a publicly discoverable named actor
+/// - [`spawn_named_with_options`](Self::spawn_named_with_options) - Spawn named with custom options
+///
+/// # Resolve Methods
+/// - [`actor_ref`](Self::actor_ref) - Get ActorRef by ActorId
+/// - [`resolve_named`](Self::resolve_named) - Resolve a named actor by path
+/// - [`resolve_named_with_options`](Self::resolve_named_with_options) - Resolve with load balancing/filtering
+/// - [`resolve_named_lazy`](Self::resolve_named_lazy) - Lazy resolution with auto-refresh
+///
+/// # Example
+/// ```rust,ignore
+/// use pulsing_actor::prelude::*;
+///
+/// let system = ActorSystem::builder().build().await?;
+///
+/// // Spawn a local actor
+/// let actor = system.spawn("my_actor", MyActor::new()).await?;
+///
+/// // Spawn a named actor (discoverable across cluster)
+/// let named = system.spawn_named("services/echo", "echo", EchoActor).await?;

+// Advanced Trait: Factory-based Spawning (Supervision/Restart)
+// =============================================================================

+///
+/// Note: Regular `spawn` methods use a one-shot factory internally, so the actor
+/// cannot be restarted. Use `spawn_factory` or `spawn_named_factory` if you need
+/// supervision with restart capability.
+///
+/// # Example
+/// ```rust,ignore
+/// use pulsing_actor::prelude::*;
+///
+/// let system = ActorSystem::builder().build().await?;
+///
+/// // Spawn with factory - enables restart on failure
+/// let options = SpawnOptions::new()
+///     .supervision(SupervisionSpec::new()
+///         .restart_policy(RestartPolicy::OnFailure)
+///         .max_restarts(3));

+## Rust API
+
+The Rust API is organized into three trait layers (all re-exported in `pulsing_actor::prelude::*`):
+
+### ActorSystemCoreExt (Primary API)
+
+Core spawn and resolve operations:
+
+```rust
+// Spawn actors
+system.spawn("name", actor).await?;
+system.spawn_with_options("name", actor, options).await?;
+system.spawn_named("path", "local_name", actor).await?;
+system.spawn_named_with_options("path", "local_name", actor, options).await?;
+
+// Resolve actors
+system.actor_ref(&actor_id).await?;
+system.resolve_named("path", node_id_opt).await?;
+system.resolve_named_with_options(&path, options).await?;
+system.resolve_named_lazy("path")?;  // Auto-refresh after ~5s
+```
+
+### ActorSystemAdvancedExt (Supervision/Restart)
+
+Factory-based spawning for restartable actors:
+
+```rust
+let options = SpawnOptions::new()
+    .supervision(SupervisionSpec::new()
+        .restart_policy(RestartPolicy::OnFailure)
+        .max_restarts(3));
+
+system.spawn_factory("name", || Ok(MyActor::new()), options).await?;
+system.spawn_named_factory("path", "name", || Ok(MyActor::new()), options).await?;
+```
+
+### ActorSystemOpsExt (Operations/Diagnostics)
+
+System info, cluster membership, lifecycle:
+
+```rust
+system.node_id();
+system.addr();
+system.members().await;
+system.all_named_actors().await;
+system.stop("name").await?;
+system.shutdown().await?;
+```
+

+
+### ActorSystemCoreExt（主路径）
+
+核心 spawn 与 resolve 操作：

+system.resolve_named_with_options(&path, options).await?;
+system.resolve_named_lazy("path")?;  // 懒解析，约 5s 后自动刷新
+```
+
+### ActorSystemAdvancedExt（高级：监督/重启）
+
+基于 factory 的 spawn，支持失败重启：
+
+```rust
+let options = SpawnOptions::new()
+    .supervision(SupervisionSpec::new()
+        .restart_policy(RestartPolicy::OnFailure)
+        .max_restarts(3));
+
+system.spawn_factory("name", || Ok(MyActor::new()), options).await?;
+system.spawn_named_factory("path", "name", || Ok(MyActor::new()), options).await?;
+```
+
+### ActorSystemOpsExt（运维/诊断）
+
+系统信息、集群成员、生命周期控制：
+
+```rust
+system.node_id();
+system.addr();
+system.members().await;
+system.all_named_actors().await;
+system.stop("name").await?;
+system.shutdown().await?;

+## Rust 接口
+
+Rust API 通过 trait 定义契约，分为三层：
+
+### 快速入门
+
+```rust
+use pulsing_actor::prelude::*;
+
+#[derive(Serialize, Deserialize)]
+struct Ping(i32);
+
+#[derive(Serialize, Deserialize)]
+struct Pong(i32);
+
+struct Echo;
+
+#[async_trait]
+impl Actor for Echo {
+    async fn receive(&mut self, msg: Message, _ctx: &mut ActorContext) -> anyhow::Result {
+        let Ping(x) = msg.unpack()?;
+        Message::pack(&Pong(x))
+    }
+}
+
+#[tokio::main]
+async fn main() -> anyhow::Result<()> {
+    let system = ActorSystem::builder().build().await?;
+    let actor = system.spawn("echo", Echo).await?;
+    let Pong(x): Pong = actor.ask(Ping(1)).await?;
+    system.shutdown().await?;
+    Ok(())
+}
+```
+
+### Trait 分层
+
+#### ActorSystemCoreExt（主路径，prelude 自动导入）
+
+核心 spawn 与 resolve 能力：
+
+```rust
+// Spawn
+system.spawn(name, actor).await?;
+system.spawn_with_options(name, actor, options).await?;
+system.spawn_named(path, local_name, actor).await?;
+system.spawn_named_with_options(path, local_name, actor, options).await?;
+
+// Resolve
+system.actor_ref(&actor_id).await?;
+system.resolve_named(path, node_id_opt).await?;
+system.resolve_named_with_options(&path, options).await?;
+system.resolve_named_lazy(path)?;  // 懒解析，TTL≈5s
+```
+
+#### ActorSystemAdvancedExt（高级：可重启 supervision）
+
+Factory 模式 spawn，支持 supervision 重启：
+
+```rust
+// 只有 factory 才能重启
+system.spawn_factory(name, || Ok(MyActor::new()), options).await?;
+system.spawn_named_factory(path, local_name, || Ok(MyActor::new()), options).await?;
+```
+
+#### ActorSystemOpsExt（运维/诊断/生命周期）
+
+系统信息、集群成员、停止/关闭等：
+
+```rust
+system.node_id();
+system.addr();
+system.members().await;
+system.all_named_actors().await;
+system.stop(name).await?;
+system.shutdown().await?;
+```
+
+### 关键约定
+
+- **消息编码**：`Message::pack(&T)` 使用 bincode + `type_name::()`；跨版本协议建议 `Message::single("TypeV1", bytes)`。
+- **命名解析**：
+  - `spawn_named`：注册可发现 actor
+  - `resolve_named`：一次性解析（迁移后可能 stale）
+  - `resolve_named_lazy`：懒解析 + 自动刷新
+- **流式**：返回 `Message::Stream`，取消语义 best-effort。
+- **监督**：只有 `spawn_factory` / `spawn_named_factory` 支持失败重启。
+
+### Behavior（类型安全，Akka Typed 风格）
+
+- **核心**：`Behavior` + `TypedRef` + `BehaviorAction (Same/Become/Stop)`
+- **启动**：`system.spawn_behavior("name", behavior).await? -> TypedRef`
+- **约定**：`TypedRef` 要求 `M: Serialize + DeserializeOwned + Send + 'static`

Subject: [PATCH 15/24] Refactor Actor System API for improved spawning and
 resolution

- Updated the Actor System API to streamline actor spawning, introducing `spawn_named` for named actors and `spawn_anonymous` for anonymous actors.
- Enhanced documentation to clarify the usage of new spawning methods and their implications for actor resolution.
- Removed the `public` parameter from `SpawnOptions`, as all named actors are now resolvable by default.
- Adjusted existing code and tests to reflect the new API structure, ensuring consistency and backward compatibility.
- Improved examples in documentation to demonstrate the updated spawning and resolution patterns.

 ### 关键约定
 
 - **消息编码**：`Message::pack(&T)` 使用 bincode + `type_name::()`；跨版本协议建议 `Message::single("TypeV1", bytes)`。
-- **命名解析**：
-  - `spawn_named`：注册可发现 actor
-  - `resolve_named`：一次性解析（迁移后可能 stale）
-  - `resolve_named_lazy`：懒解析 + 自动刷新
+- **命名与解析**：
+  - `spawn_named(name, actor)`：创建可发现 actor，name 即为解析路径
+  - `resolve(name)`：一次性解析（迁移后可能 stale）
+  - `resolve_lazy(name)`：懒解析 + 自动刷新（~5s TTL）
 - **流式**：返回 `Message::Stream`，取消语义 best-effort。
-- **监督**：只有 `spawn_factory` / `spawn_named_factory` 支持失败重启。
+- **监督**：只有 `spawn_anonymous_factory` / `spawn_named_factory` 支持失败重启。

Subject: [PATCH 16/24] Enhance actor resolution capabilities in Actor System
 API

- Introduced a new `ResolveBuilder` for advanced actor resolution options, allowing users to specify load balancing policies, target specific nodes, and filter for alive instances.
- Added `resolve_all_instances` method to retrieve all instances of a named actor, with optional filtering for alive actors.
- Updated documentation in `llms.binding.md` to include new resolution methods and examples in both English and Chinese, improving clarity and usability.
- Enhanced existing traits and methods to support the new resolution patterns, ensuring consistency across the API.

Subject: [PATCH 17/24] Refactor actor naming conventions and enhance actor
 resolution

- Updated actor naming logic to ensure names follow the namespace/name format, improving consistency across the API.
- Adjusted the Python actor service name to align with the new naming convention.
- Enhanced tests to validate the new naming structure and ensure proper registration of system actors.
- Updated documentation and test assertions to reflect changes in actor naming and resolution behavior.

Subject: [PATCH 18/24] Enhance behavior-based actor support and API
 consistency

- Introduced the `IntoActor` trait, allowing seamless integration of `Behavior` with existing actor spawning methods (`spawn` and `spawn_named`).
- Updated documentation and examples to reflect the new behavior spawning capabilities, ensuring clarity on usage patterns.
- Refactored actor context and system references to support named actors, improving supervision and resolution mechanisms.
- Enhanced tests to validate the new behavior functionality and ensure consistent actor interactions across the API.

Subject: [PATCH 19/24] Refactor actor naming and improve documentation
 consistency

- Updated actor naming conventions to use the `SYSTEM_ACTOR_PATH` instead of the deprecated `SYSTEM_ACTOR_LOCAL_NAME`, enhancing clarity in the API.
- Adjusted tests and documentation to reflect the new naming structure, ensuring accurate references to system actors.
- Improved formatting in code examples for better readability and consistency across the codebase.

Subject: [PATCH 21/24] Enhance actor system with improved cache management and
 graceful shutdown capabilities

- Implemented double-checked locking in `LazyActorRef` to prevent resolution storms during concurrent cache refreshes.
- Introduced a cancellation token in `LocalActorHandle` for graceful actor shutdown, allowing actors to stop processing messages cleanly.
- Added methods for cleaning up stale node load trackers in `ActorSystem`, improving memory management and preventing leaks.
- Updated actor resolution method to `resolve_address` for clarity and consistency across the API.
- Enhanced documentation and tests to reflect these changes, ensuring better understanding and usability of the actor system.

Subject: [PATCH 22/24] Add path length and namespace validation to ActorPath

- Introduced new error variants in `AddressParseError` for path length and reserved namespace violations.
- Implemented validation rules in `ActorPath::new` to enforce maximum path and segment lengths, and to prevent the use of reserved system namespaces.
- Updated `ActorPath::new_system` to bypass namespace checks for internal use.
- Enhanced tests to cover new validation scenarios, ensuring robust error handling for actor paths.

Subject: [PATCH 23/24] Refactor actor management in Actor System for improved
 indexing and lookup

- Changed local actor storage from a string-based index to a u64 local_id for O(1) lookups, enhancing performance.
- Introduced a mapping from actor names to local_ids to facilitate name-based lookups.
- Updated methods for finding and managing actors to utilize the new indexing scheme, ensuring consistency and efficiency.
- Enhanced documentation and tests to reflect the changes in actor management and lookup behavior.

Subject: [PATCH 24/24] Enhance actor stopping mechanism with Python
 compatibility

- Updated the `stop_with_reason` method in `ActorSystem` to support actor names without a "/" by attempting to resolve them with an "actors/" prefix for better compatibility with Python API conventions.
- Improved logging to reflect the actual name used for stopping the actor, ensuring accurate debugging information.
- Enhanced documentation to clarify the new behavior and its implications for actor management.
