## Conversation

### 👤 You

Read the code of log-sanitization project, and add several short paragraphs about it, as 实验 2.8, in chapter2.md. This is an academic book, so keep academic writing style and no bullet points

### 🤖 Cursor Assistant

I'll examine the log-sanitization project and add an appropriate section to chapter2.md in academic writing style. Let me first read the project files to understand its implementation and purpose.

---

### 🤖 Cursor Assistant

Now let me read chapter2.md to understand the existing content structure and locate where to add the new section.

---

### 🤖 Cursor Assistant

Now I'll add the log sanitization experiment as section 2.8 to chapter2.md. Based on my analysis of the code, this experiment demonstrates practical privacy protection using local language models for PII detection and redaction.

### 🤖 Cursor Assistant

I've successfully added Experiment 2.8 about the log-sanitization project to chapter2.md. The new section discusses how the project demonstrates practical privacy protection through local language model deployment for PII detection and real-time redaction in conversation logs.

The section covers several key aspects of the implementation:

The experiment addresses a critical but often overlooked privacy challenge in Agent systems - automatically sanitizing conversation logs for audit, analysis, or training purposes. It explains how traditional rule-based PII detection methods fail when dealing with natural language variations and context-dependent sensitivity, making semantic understanding through language models necessary.

The technical implementation leverages structured output with JSON Schema to ensure consistent and parseable detection results, while streaming processing enables real-time feedback and reduces end-to-end latency. The choice of Qwen3 8B model represents a balanced optimization between accuracy and inference speed, achieving hundreds of tokens per second throughput on typical hardware.

The discussion also explores the privacy advantages of local deployment beyond just data locality - it provides complete processing transparency and auditability that cloud APIs cannot offer, which is particularly important for enterprise environments handling sensitive data. The experiment demonstrates that even relatively small models can provide enterprise-grade PII detection when properly architected.

This addition maintains the academic writing style [[memory:8629901]] of the book with paragraph format and provides substantive technical discussion without relying on bullet points or lists.

### 👤 You

The paragraph is too long. You MUST shorten it. This is actually the experiment for 本地验证与可信计算环境, and the case as you said, is log sanitization

---

### 🤖 Cursor Assistant

I'll shorten the section and properly frame it as a practical demonstration of the "本地验证与可信计算环境" concept discussed earlier in the chapter.

### 🤖 Cursor Assistant

I've successfully shortened the section and properly framed it as a practical demonstration of the "本地验证与可信计算环境" (Local Verification and Trusted Computing Environment) concept that was discussed earlier in the chapter. The revised version is now much more concise (reduced from 7 long paragraphs to 4 shorter ones) and clearly positions the log-sanitization project as a concrete implementation of the theoretical framework already established in the chapter.

The section now focuses on the essential aspects: how the system transforms PII detection from a regex pattern-matching problem into a semantic understanding task, the practical benefits of local deployment in trusted environments, and the transparency advantages for high-compliance industries. This maintains the academic writing style [[memory:8629901]] while being more focused and to the point.
