Put a term list at the top of the document in table form (
```
| Term | Description |
```
). Every specialised term used in the body must be defined in this list at first occurrence.
A term-list entry defines what the term is in one or two sentences. The functional or behavioural detail goes in the body, not in the term list.
Even widely recognised proper nouns (industry-standard product names, infrastructure components, etc.) get defined here. Assume the reader does not know them.
When defining a compound term, define the constituent words too. If the compound has three words, give all three their own entries — readers cannot be expected to infer one from another.

在文档顶部以表格形式（
```
| Term | Description |
```
）放置术语列表。正文中使用的每个专业术语都必须在首次出现时在此列表中定义。
术语列表中的条目需用一两句话定义该术语是什么。功能或行为细节应放在正文中，而非术语列表里。
即便是广为人知的专有名词（行业标准产品名称、基础设施组件等）也需在此定义。假设读者不了解这些术语。
定义复合术语时，也需定义其组成词汇。如果复合术语包含三个单词，需为这三个单词分别创建条目——不能假设读者可以通过其中一个推断出另一个。

Use Mermaid for diagrams. Do not use ASCII art.
Every node label is a term that exists in the term list. Do not introduce a new term inside a diagram.
Do not put
```
<br/>
```
inside a Mermaid node. Many renderers display the literal HTML tag. If a line break is needed, separate with
```
/
```
or shorten the text to fit one line.
For diagrams with four or more nodes, or where any label is long, use
```
graph TD
```
(top-down).
```
graph LR
```
(left-right) collapses long-label graphs into an unreadable horizontal strip.

Do not gloss details with vague language. Subjects, objects, and verbs must be explicit.
A phrase like "A uses B to do X" must specify what A is and why A is needed for X.
Avoid vague verbs like "receives" or "passes". Spell out who does what to bring the state about (e.g. "receives the address" → "the platform allocates the address automatically").
Do not require the reader to make a leap between steps. Every step's causal connection to the next is explicit.
Describe the mechanism in its general form first; tie it to specific named instances afterwards as "in case X, ...". Do not anchor the whole description to a single proper-noun example.
