# Model Card Contract

Each human-readable model card in `cards/` must include the sections below.

Section contents should be Chinese when the source material is Chinese. English may appear in IDs, aliases, source terms, and field labels.

## Required Sections

## 模型名称

The human-readable model name.

## 模型 ID

The stable machine ID used by model JSON, source excerpts, regression cases, selector rules, and indexes.

## 一句话定义

One concise sentence explaining what the model does.

## 模型类型

The model type, aligned with `schemas/model_card.schema.json`.

## 所在流程位置

Where the model belongs in the processing pipeline.

## 来源文章

Source article IDs and titles.

## 来源证据片段

Evidence excerpt IDs and what each excerpt supports.

## 核心问题

The core question this model answers.

## 核心机制

The reusable mechanism or operating logic of the model.

## 输入类型

Inputs the model can accept.

## 输出类型

Outputs the model should produce.

## 适用场景

When the model should be called.

## 不适用场景

When the model should not be called.

## 调用关键词

Trigger keywords or expressions that suggest the model may apply.

## 负向触发条件

Expressions, task types, or contexts that should suppress the model.

## 相关模型

Models that can be called before, after, or alongside this model.

## 冲突模型

Models or flows that should not be used together without arbitration.

## 学科底座关联

Disciplines, theories, or knowledge bases that anchor the model.

## 常见误用

Common misuse patterns.

## 失败信号

Signals that the model was called incorrectly or produced unstable output.

## 可信度等级

The current confidence level and why.

## 稳固性状态

The current stability level and whether stabilization is still required.

## 稳定性评估

Assessment across concept clarity, mechanism stability, boundary clarity, source evidence quality, and regression performance.

## 回归测试状态

Regression status and current coverage.

## 示例输入

Representative inputs.

## 示例输出

Representative outputs.

## 输出契约

The expected structure or elements of model output.

## 深度控制

Depth limits, stop conditions, or overuse warnings.

## 产品化建议

Notes for selector, workflow, product integration, or future stabilization.

## 版本信息

Version, last updated date, and draft/stability status.

## Additional Sections

Cards may include additional explanatory sections after the required sections.

Required sections may contain `无` only when the model genuinely has no value for that field, and the reason must be clear.
