Severity Scoring Formula

严重程度评分公式

text

Page Score = 100 - (sum of weighted findings)

Weights:
  Critical (high confidence, both sources):  -15 points
  Critical (high confidence, single source): -10 points
  Critical (medium confidence):               -7 points
  Critical (low confidence):                  -3 points
  Serious (high confidence):                  -7 points
  Serious (medium confidence):                -5 points
  Serious (low confidence):                   -2 points
  Moderate (high confidence):                 -3 points
  Moderate (medium confidence):               -2 points
  Moderate (low confidence):                  -1 point
  Minor:                                      -1 point

Floor: 0 (minimum score)

Score Grades

评分等级

Score	Grade	Meaning
90-100	A	Excellent - minor or no issues, meets WCAG AA
75-89	B	Good - some issues, mostly meets WCAG AA
50-74	C	Needs Work - multiple issues, partial WCAG AA compliance
25-49	D	Poor - significant accessibility barriers
0-24	F	Failing - critical barriers, likely unusable with AT

分数	等级	含义
90-100	A	优秀 - 仅有轻微问题或无问题，符合WCAG AA标准
75-89	B	良好 - 存在少量问题，基本符合WCAG AA标准
50-74	C	有待改进 - 存在多个问题，部分符合WCAG AA合规要求
25-49	D	较差 - 存在显著无障碍障碍
0-24	F	未通过 - 存在致命障碍，使用AT很可能无法正常访问

Confidence Levels

置信度等级

Level	Weight	When to Use
High	100%	Confirmed by axe-core + agent, or definitively structural (missing alt, no labels, no lang)
Medium	70%	Found by one source, likely issue (heading edge cases, questionable ARIA, possible keyboard traps)
Low	30%	Possible issue, needs human review (alt text quality, reading order, context-dependent link text)

等级	权重	适用场景
高	100%	由axe-core + Agent共同确认，或明确属于结构性问题（缺失alt属性、无标签、无lang属性）
中	70%	由单一来源发现，大概率是问题（标题边缘情况、有疑问的ARIA、可能存在键盘陷阱）
低	30%	可能存在问题，需要人工审核（alt文本质量、阅读顺序、依赖上下文的链接文本）

Source Correlation

来源相关性

Issues found by both axe-core AND agent review are automatically upgraded to high confidence regardless of individual confidence ratings.

同时被axe-core和Agent审核发现的问题，无论单独的置信度评级如何，都会自动升级为高置信度。

Cross-Page Pattern Classification

跨页面模式分类

Pattern Type	Definition	Remediation ROI
Systemic	Same issue on every audited page	Highest - usually layout/nav, fix once
Template	Same issue on pages sharing a component	High - fix the shared component
Page-specific	Unique to one page	Normal - fix individually

模式类型	定义	修复投资回报率
系统性	所有被审计页面都存在相同问题	最高 - 通常是布局/导航问题，修复一次即可
模板级	共享同一组件的页面存在相同问题	高 - 修复共享组件即可
页面专属	仅单个页面存在的独特问题	普通 - 单独修复即可

Change Classification

变更分类

Status	Definition
Fixed	Issue was in previous report but no longer present
New	Issue not in previous report, appears now
Persistent	Issue remains from previous report
Regressed	Issue was previously fixed but has returned

状态	定义
已修复	上一次报告中存在的问题现已不存在
新增	上一次报告中不存在，本次新出现的问题
持续存在	上一次报告中存在的问题本次仍存在
回退	之前已修复的问题再次出现

Progress Metrics

进度指标

Issue reduction:
```
(fixed / previous_total) * 100
```
Score change:
```
current_score - previous_score
```
Pages improved: count of pages with higher scores than previous audit
Trend: improving (score up 5+), stable (within 5), declining (score down 5+)

问题减少率：
```
(fixed / previous_total) * 100
```
分数变化：
```
current_score - previous_score
```
页面改进数： 分数高于上一次审计的页面数量
趋势： 提升（分数上涨5分及以上）、稳定（波动在5分以内）、下降（分数下跌5分及以上）
