Rosetta Experimental Learning V2 Creation 260109

Rosetta Experimental Learning V2 Skill Creation Output

Timestamp: 2026-01-09 20:07:42 User Request: Create an enhanced V2 version of rosetta-experimental-learning skill

User Requirements

The user requested comprehensive modifications to the original rosetta-experimental-learning skill with the following enhancements:

1. Add “定义核心’句式’” (Identify Core Sentences) Framework

• Purpose: Before entering any field, break it down into basic representative “sentences” or fundamental units
• Cross-domain examples required: Programming languages, business models, databases
• Operation principles: Find bottom-layer logic that once mastered helps understand the whole structure

2. Add “解决什么痛点” (What Pain Point It Solves) to All Answers

• Every layer must answer: What pain point does it solve?
• What happens if this layer doesn’t exist?
• How is it solved?

3. Sentinel Value Tracking Method (哨兵值追踪法)

• Use unique, easily recognizable values: 0xBAB1CAFE, 0xDEADC0DE, 0xCAFEBABE
• Tagging with Sentinel Values for tracking data flow
• Replace generic “tracers” with specific sentinel values in source code

4. Four-Dimension Analysis SOP (四维度分析SOP)

Teach analysis through 4 dimensions:

• Resources & Storage: Variable naming, space usage
• Protocols & Conventions: Parameter passing, cleanup responsibility
• Logic Control: Conditionals, loops, jumps
• Bottom Interaction: System calls, external communication

Key Enhancements Summary

Enhancement 1: Step 0 - Define Core “Sentences” Framework

Added a completely new step at the beginning of the methodology:

### 第零步：定义核心"句式"（Identify Core Sentences）⭐ 新增

**目标**：在进入任何新领域之前，先将该领域拆解为一系列最基础的、具有代表性的"句式"或基本单元。

**核心思想**：
- 每个领域都有其"基本词汇"（原子操作）
- 一旦掌握这些基本单元，就能理解整个系统的结构
- 这些"句式"是理解该领域的钥匙

Cross-domain examples provided:

• Programming Languages (Rust): Variable declaration, function definition, ownership transfer, pattern matching, error handling
• Business Models (SaaS): CAC, retention rate, conversion path, cash flow, LTV
• Databases (MySQL): CREATE TABLE, INSERT, SELECT, CREATE INDEX, transactions

Why this matters:

• 🔑 These “sentences” are the minimum knowledge set for understanding the domain
• 🔑 Mastering them gives you 80% of the core logic
• 🔑 They serve as baseline references for subsequent experiments

Enhancement 2: Step 1 Enhanced with Pain Point Analysis

Original: Simple layer table with name, data form, observability

Enhanced: Added 3 new columns:

Example from skill:

| **层级1** | 源代码层 | .java 文本 | **痛点**：代码改了不生效，不知道是编译问题还是缓存问题。<br>**解决什么**：理解代码如何变成可执行文件 | 无法追踪代码到指令的转换过程 | `javac`编译 | ✅ 编辑器查看 |

Impact: Every layer now clearly explains:

1. What real-world problem it solves
2. What would happen without it
3. How it’s implemented/solved

Enhancement 3: Sentinel Value Tracking Method (哨兵值追踪法)

Completely rewrote Step 4 to use “Sentinel Values” instead of generic “tracers”.

Design Principles:

| 原则 | 说明 | 示例 |
|------|------|------|
| ✅ **独特性** | 一眼就能认出，不会自然出现 | `0xCAFEBABE`, `0xBAB1CAFE`, `0xDEADC0DE` |
| ✅ **语义化** | 让你知道这是你故意放的 | `SENTINEL_VAR_001`, `TRACER_FIELD` |
| ✅ **多类型** | 覆盖数值、字符串、对象 | 整数、浮点数、字符串、数组、对象 |
| ✅ **可搜索** | 在十六进制、字符串中都能搜索到 | `grep -r "DEADBEEF"`, `grep -r "SENTINEL"` |

Recommended Sentinel Values:

// 数值哨兵值（易于在十六进制编辑器中搜索）
0xCAFEBABE      // 经典的Java魔术数字
0xBAB1CAFE      // "Baby Cafe" - 便于记忆
0xDEADC0DE      // "Dead Code" - 明确含义
0xFEEDFACE      // "Feed Face" - 有趣好记
0xFADEBABE      // "Fade Baby" - 发音相近

// 字符串哨兵值（易于在文本中搜索）
"SENTINEL_VAR_001"
"TRACER_FIELD"
"MARKER_TOKEN_ABC123"
"ROSETTA_STONE_SENTINEL"

Core Sentences Baseline Code Example:

public class SentinelTracer {
    // ====== 核心句式1：变量声明 ======
    private static final int SENTINEL_INT = 0xDEADBEEF;

    // ====== 核心句式2：函数定义 ======
    public static int sentinelMethod(int param) {
        int local = SENTINEL_INT + param;
        return local;
    }

    // ====== 核心句式3：条件控制 ======
    public void conditionalBranch(boolean flag) {
        if (flag) {
            System.out.println("SENTINEL_IF_TRUE");
        } else {
            System.out.println("SENTINEL_IF_FALSE");
        }
    }

    // ... more core sentences with sentinel values
}

Enhancement 4: Four-Dimension Analysis SOP (四维度分析SOP)

Added a comprehensive 4-dimension analysis framework:

Dimension 1: Resources & Storage (资源与存储)

Goal: Understand how “variables” are named and their space usage

Analysis Steps:

1. Identify naming conventions (search for sentinel values like 0xDEADBEEF)
2. Measure space usage (how many bytes each variable occupies)
3. Understand storage strategy (stack frame, register, memory layout)

Example Output Table:

Tools: javap -v -p Class, objdump -d binary, wireshark

Dimension 2: Protocols & Conventions (协议与约定)

Goal: Understand how different modules pass information and who’s responsible for cleanup

Analysis Steps:

1. Identify calling conventions (how parameters are passed)
2. Determine caller/callee responsibilities (who saves what)
3. Understand cleanup (how to restore state after function returns)

Example Output Table:

Tools: javap -c -v Class, objdump -d binary, tcpdump, wireshark

Dimension 3: Logic Control (逻辑控制)

Goal: Observe how the system handles conditionals (If/While/For) and jumps

Analysis Steps:

1. Identify conditional branches (search for sentinel value conditionals)
2. Trace loop control (observe loop implementation at bottom layer)
3. Understand jump mechanisms (how jump targets are determined)

Example Output Table:

Tools: javap -c Class, objdump -d binary | less, GDB disassemble / si

Dimension 4: Bottom Interaction (底层交互)

Goal: Find out how the system communicates with the outside world or higher privilege levels

Analysis Steps:

1. Identify system call interfaces (search for sentinel value system calls)
2. Understand parameter passing (how to pass parameters to external systems)
3. Observe return value handling (how external system returns are processed)

Example Output Table:

Tools: javap -c -p Class, -XX:+PrintCompilation, strace, tcpdump, ltrace

Complete Four-Dimension Analysis Example

The skill includes a complete worked example showing how to analyze Java’s conditional statement:

High-level code:

if (SENTINEL_INT == 0xDEADBEEF) {
    System.out.println("SENTINEL_IF_TRUE");
} else {
    System.out.println("SENTINEL_IF_FALSE");
}

Dimension 1 - Resources & Storage:

搜索：grep "SENTINEL_INT" bytecode.txt
找到：#2 = Integer 0xdeadbeef

分析：
- SENTINEL_INT 被编译为常量 #2
- 存储在常量池中（Constant Pool）
- 占用4字节（int类型）
- 使用iconst_0指令加载到操作数栈

Dimension 2 - Protocols & Conventions:

分析：
- Java使用栈式VM，参数通过栈传递
- if_icmpeq执行后，结果留在栈顶
- 跳转目标由字节码偏移量指定

Dimension 3 - Logic Control:

分析：
- if-else编译为条件跳转+goto
- ifeq表示"如果相等"（if equal）
- false分支先执行（跳过true分支）
- true分支后执行（跳过false分支）

Dimension 4 - Bottom Interaction:

分析：
- getstatic：获取静态字段System.out
- ldc：加载字符串常量到操作数栈
- invokevirtual：调用实例方法println
- 最终通过JNI调用native方法写输出

Execution Checklist (Added to Skill)

The skill includes a comprehensive checklist to ensure nothing is missed:

Step 0: Define Core Sentences

• List 5-10 core “sentences” for the domain
• Design example code for each sentence (with sentinel values)
• Ensure each sentence is basic and indispensable
• Organize sentences into documentation

Step 1: Define Layers (Pain Point Driven)

• List all layers data flows through
• Confirm data form at each layer
• Clarify what pain point each layer solves
• Choose easiest layer to start

Step 2: Define Checkpoints

• Find data’s mandatory path
• Confirm checkpoint observability
• Draw horizontal causal chain diagram
• Record checkpoint purpose

Step 3: Deploy Tools

• Select observation tools
• Test tool availability
• Prepare search commands

Step 4: Inject Sentinel Values

• Design unique sentinel values (0xCAFEBABE)
• Embed in baseline code containing core sentences
• Execute transformation
• Search for sentinel value markers
• Perform four-dimension analysis:
  • Dimension 1: Resources & Storage
  • Dimension 2: Protocols & Conventions
  • Dimension 3: Logic Control
  • Dimension 4: Bottom Interaction

Key Principles Highlighted in Skill

1. 主动观测 > 被动阅读

   • 文档告诉你"应该是什么"，实验展示"实际是什么"

2. 哨兵值必须独特

   • ❌ a = 1
   • ✅ a = 0xCAFEBABE
   • ✅ s = "SENTINEL_TOKEN_001"

3. 先定义"句式"，再追踪

   • Don’t skip Step 0, start tracking directly
   • “Sentences” are the keys to understanding the domain

4. 四维度全覆盖

   • Don’t focus on just one dimension
   • Analyze all four dimensions:
     • Resources & Storage
     • Protocols & Conventions
     • Logic Control
     • Bottom Interaction

5. 相信观测，质疑假设

   • If phenomenon conflicts with documentation, trust observation

6. 必须破坏性验证

   • Normal scenarios don’t show boundaries
   • Abnormal scenarios reveal real behavior
