# A 入口与边界层

## 1. Scope

```text
layer_id: A
function: de-label the entry phenomenon and define the boundary
primary_nodes: A1, A1-a
```

本层处理 `失望性情感隔离` 的入口问题：它可以作为经验命名，但不能直接偷渡病因、诊断或干预方案。

## 2. Main Claims

```text
- “失望性情感隔离”不是最终理论中心，而是入口现象。
- 心理学自媒体容易制造专业感，但缺少严肃知识所需的边界、证据、限定条件和反例意识。
- 原生家庭可能是近场高权重系统，但不能被道德化为万能归因。
- 正确处理方式是先区分现象、病因、解释模型、干预模型。
```

## 3. Source Material Layer

Primary blocks:

| block_id | role |
| --- | --- |
| R01-B001 | entry framing |
| R01-B002 | article label and user skepticism |
| R01-B003 | symptom/state vs diagnosis boundary |
| R01-B005 | psychology-media knowledge imitation |
| R01-B006 | corrected stance |

Cross-links:

```text
B1: single-cause attribution critique
B2: relationship prediction and isolation mechanism
```

## 4. Distortion Guard

Do not turn this layer into a psychology-label explainer. Its function is to prevent the whole discussion from being captured by the label.

## 5. Material Extraction

| material_id | source_blocks | type | extracted material | downstream use |
| --- | --- | --- | --- | --- |
| A-M01 | R01-B002, R01-B003 | concept boundary | `失望性情感隔离` should be treated as an entry description of a state, not as a diagnosis or causal conclusion. | article opening; anti-labeling rule |
| A-M02 | R01-B003 | clinical caution | Emotional numbness / detachment may relate to pressure, trauma, depression, medication effects, anxiety exhaustion, or other factors; the source rejects a single childhood-love explanation. | model guardrail; source-faithful caveat |
| A-M03 | R01-B005 | media critique | Psychology-media content creates authority through terminology, but often omits evidence, scope, counterexamples, and intervention boundaries. | critique section; knowledge-quality rubric |
| A-M04 | R01-B004, R01-B006 | reframing move | The correct move is not to ask “which label is this,” but to ask what mechanism, scope, and governance problem this state reveals. | transition into B/C layers |

## 6. Reusable Claims

```text
- A psychological label is useful only as an entrance if it does not smuggle in a cause.
- Naming pain is not the same as explaining it, and explaining it is not the same as knowing how to intervene.
- The first governance act is to rescue the experience from a low-quality label.
```

## 7. Open Use Notes

This layer is suitable for article introduction and for a future `knowledge-quality` checklist. It should not become the main model layer.
