feat: demo-pmd 样本工程入库 + Windows spawn cmd EINVAL 修复 + 实测报告清理

- data/demo-pmd 全量入库（26 源文件 + pom/mvnw/lib/reports），.gitignore 排除 target/
- 归档 demo-pmd 实测覆盖率报告（279/279 全覆盖）至 reports/
- 删除 4 份覆盖率报告中的后续建议/实测进度总览（全部实测已收官）
- 修复 Windows spawn .cmd/.bat EINVAL（auxClasspath.ts 经 cmd.exe /d /s /c 间接执行）

 2. ✅ 内置配置全覆盖达成（126/126 种规则，零解析错误）
 3. ✅ 「内置配置回退」路径完整验证（工程无配置文件的场景）
 
-**后续建议**（如需继续扩展验证）：
-
-- **其他 3 个工程复测**：`demo-sqlfluff`、`demo-pmd`、`demo-stylelint` 按同样方法（先本地模拟基线 → 实测比对），其中 PMD 注意 Java 版本与 ruleset、SQLFluff 注意 dialect 与 AL06 样例、Stylelint 注意配置优先级。
-- **「工程配置优先」路径补验**（可选）：若后续想验证插件发现工程配置的行为，可在工程根添加 `eslint.config.mjs` 并以工程根为第一个工作区文件夹打开，预期插件改用工程配置（诊断会有差异，属正常）。

+# demo-pmd 插件实测覆盖率报告
+
+> **工程**：`demo-pmd`（PMD 内置规则集形态：`jars/pmd/pmd-java-ruleset.xml` + `pmd-jsp-ruleset.xml`）
+> **测试对象**：插件 PMD 适配器（引擎 PMD 7.26.0，Java 269 条 / JSP 10 条内置规则）
+> **实测日期**：2026-08-26（当日完成含辅助 classpath 的全量复测收官）
+> **比对基线**：插件同版本引擎 + 同规则集独立复现的基线（比对键 = 规则 + 行号；JSP 另含三层架构逐层复现）
+
+---
+
+## 一、核心结论
+
+| 指标 | 结果 | 状态 |
+|---|---|---|
+| 插件行为一致性（vs 基线） | **1813/1813 条逐条一致，零偏差** | ✅ 100% |
+| Java 规则覆盖率 | **269/269 种（100%）** | ✅ 7/7 类满覆盖 |
+| JSP 规则覆盖率 | **10/10 种（100%）** | ✅ 全覆盖 |
+| 规则总覆盖率 | **279/279 种（100%）** | ✅ 全覆盖 |
+| 解析错误 | **0 处** | ✅ |
+| 静态诊断总数 | 1819 条（PMD 1813 + ESLint 6） | — |
+
+**实测完全达成全覆盖基准**：演示工程全部 26 个文件（23 Java + 3 JSP）的插件报告，共 1813 条 PMD 静态诊断与独立基线**规则名、行号逐条完全一致**，零误报、零漏报、零解析错误；Java 269 条与 JSP 10 条内置规则**全部触发**，两类规则集均达 100% 覆盖。**PMD 适配器静态分析链路（规则加载、Java/JSP 双语言路由、scriptlet 包装、诊断映射、辅助 classpath 自动解析）验证通过。**

+
+## 二、逐文件比对（实测 vs 基线）
+
+**Java 23 份**（基线 = PMD 7.26.0 + `pmd-java-ruleset.xml`；★ 为启用辅助 classpath 后复测的文件）：
+
+| 文件 | 实测 | 基线 | 一致性 | 说明 |
+|---|---:|---:|---|---|

+| **Java 合计** | **1769** | **1769** | **✅ 零偏差** | — |
+
+> ★ 三份复测说明：`JUnit4RulesTest` / `JUnit5ArgOrderTest` / `LoggerDemo` 首轮以无 classpath 模式测得 51 / 7 / 10 条（与 noaux 基线逐条一致）；辅助 classpath 生效后复测为 67 / 9 / 11 条（与 aux 基线逐条一致），新增的 19 条全部来自 4 个类型解析规则（见第三节）。两轮均零偏差。
+
+**JSP 3 份**（基线 = 三层架构逐层复现，见第四节）：
+
+| 文件 | PMD 实测 | PMD 基线 | ESLint | 一致性 |

+
+> 比对方法：将插件报告中的每条静态诊断（规则名 + 行号）与基线做多重集合比对；26 个文件全部 `missing = 0`、`extra = 0`。
+
+---
+
+## 三、覆盖率分布与最后 4 条规则的达成
+
+**Java 规则集按类别**（269 条，7 类，全部满覆盖）：
+
+| 类别 | 总数 | 已覆盖 | 覆盖率 |
+|---|---:|---:|---:|
+| Error Prone | 90 | 90 | 100% |
+| Best Practices | 58 | 58 | 100% |
+| Code Style | 57 | 57 | 100% |
+| Design | 29 | 29 | 100% |
+| Performance | 24 | 24 | 100% |
+| Multithreading | 9 | 9 | 100% |
+| Security | 2 | 2 | 100% |
+| **合计** | **269** | **269** | **100%** |
+
+**JSP 规则集**：bestpractices / codestyle / design / errorprone 四类共 10 条全部触发（`JspFix` 贡献 6 种、`DemoJsp` 贡献 6 种，并集 10/10）。
+
+**最后 4 条规则的两阶段达成过程**：
+
+| 规则 | 类别 | 触发依赖 | 达成方式 |
+|---|---|---|---|
+| `UnitTestAssertionsShouldIncludeMessage` | Best Practices | JUnit `assertEquals` 类型解析 | classpath 后 `JUnit4RulesTest` +15、`JUnit5ArgOrderTest` +1 |
+| `SimplifiableTestAssertion` | Best Practices | JUnit 断言 API 类型解析 | classpath 后 `JUnit4RulesTest` +1 |
+| `AssertEqualsArgumentOrder` | Error Prone | JUnit `assertEquals` 签名解析 | classpath 后 `JUnit5ArgOrderTest` +1 |
+| `UseCorrectExceptionLogging` | Error Prone | commons-logging `Logger` 类型解析 | classpath 后 `LoggerDemo` +1 |
+
+该 4 条规则依赖**辅助 classpath 的类型解析**，触发条件是工程根有 `pom.xml`/`build.gradle` 且插件成功解析依赖。演示工程 `pom.xml` 声明了 junit 4.13.2、junit-jupiter-api 5.10.2、commons-logging 1.3.4、slf4j-api 2.0.16（恰为 4 条规则所需），配合 `mvnw` 包装器在复测轮成功解析依赖后全部触发。
+
+---
+
+## 四、JSP 三层架构验证
+
+插件对 `.jsp` 文件采用三层分析（`src/adapters/jsp.ts`），本次全部逐层复现：
+
+1. **层 1 · PMD JSP 规则集**：整文件跑 `pmd-jsp-ruleset.xml`（10 条规则）；
+2. **层 2 · scriptlet 包装**：`<% %>`/`<%! %>`/`<%= %>` 分别按 statement/declaration/expression 三种模板包装成合法 Java 类，跑 Java 规则集，行号经 headerLines 偏移精确映射回原文件（`JspFix` 的 28 条 scriptlet 诊断零行号误差）；
+3. **层 3 · ESLint**：`<script>` 块内容交 ESLint 适配器（`no-var`、`no-unused-vars`、`no-undef`）。
+
+三层合计 50 条诊断（44 PMD + 6 ESLint）与报告完全一致。两层补充验证：
+
+- **AI 审查补位 security 盲区**：`pmd-jsp-ruleset.xml` 未引用 JSP security 分类（`IframeMissingSrcAttribute`、`NoUnsanitizedJSPExpression` 不在规则集内），`SecurityDemo.jsp` 的 8 条 AI 建议恰好覆盖了该盲区（2 条 XSS 转义 + 3 条 iframe 问题）。
+- **超时降级容错**：`MultiPerfSecurity.java`（1750+ 行、190 条诊断）AI 审查 301s 超时后，报告自动降级为纯静态分析并明确标注，静态部分不受影响。
+
+---
+
+## 五、诊断分布统计
+
+**按严重级别**（PMD 静态 1813 条）：
+
+| 级别 | 数量 | 占比 |
+|---|---:|---:|
+| error（🔴） | 288 | 15.9% |
+| warning（🟡） | 1471 | 81.1% |
+| info（🔵） | 54 | 3.0% |
+
+**按语言**：Java 1769 条 · JSP 44 条（另 ESLint 6 条）。
+
+**按文件 Top5**：DesignErrorProne 762 · BestPracticesCodeStyle 517 · MultiPerfSecurity 190 · GodClassDemo 79 · JUnit4RulesTest 67。
+
+> 注：26 份报告另有 AI 审查建议 103 条（平均耗时 155.3s，区间 52.0s~301.2s），属 AI 增强能力，不计入静态规则覆盖口径。
+
+---
+
+## 六、实测环境判定与缺陷修复记录
+
+实测报告的文件路径与预期部署一致（`f:\XunHeCode\演示资料\demo-pmd\src\...`，Java 23 文件 + `src/jsp/` 3 文件，共 26 个源文件全部覆盖、无遗漏）。
+
+**辅助 classpath 两阶段验证**：
+
+1. **首轮（无 classpath 模式）**：插件当时无法解析依赖，26 个文件以无辅助 classpath 模式运行，1794 条诊断与 noaux 基线逐条一致。
+2. **复测轮（classpath 模式）**：依赖解析打通后，3 个 JUnit/日志样例文件复测（67 / 9 / 11 条），与 aux 基线逐条一致；其余 20 个文件经本地 aux 基线逐一核验，诊断数均不变（其代码不含依赖类型解析场景）。
+
+**过程中发现并修复的插件缺陷**（本轮测试的额外收获）：Windows 下插件直接 `spawn` 拉起 `mvnw.cmd` 会抛 `EINVAL`（Node 18.20+/20.12+ 修复 CVE-2024-27980 后，无 shell 执行 `.cmd`/`.bat` 一律被拒绝），导致辅助 classpath 解析**静默失败**且仅 `console.warn` 降级——影响所有 Windows 用户的 Maven/Gradle 依赖解析。已在 `src/services/auxClasspath.ts` 修复（`.cmd`/`.bat` 经 `cmd.exe /d /s /c` 间接执行），编译验证通过并提交（`ab9c386`）。复测轮的 3 份报告即为修复生效后的实测结果。
+
+---
+
+## 七、数据口径说明
+
+| 项 | 说明 |
+|---|---|
+| 覆盖率口径 | Java 269 条 = `pmd-java-ruleset.xml` 经 PMD `RuleSetLoader` API 实际加载数（7 类别引用 + exclude 排除后）；JSP 10 条同法核验；纯规则口径，不含 parse-error |
+| 比对引擎 | PMD 7.26.0（与插件 `jars/pmd` 内置引擎逐字一致），JDK 17 运行 |
+| 基线数据 | noaux 基线：`pmd-baseline-noaux/`（初批 14）、`pmd-batch2-noaux/`（批 2）、`/tmp/*-noaux.json`（批 3+收尾 4）；aux 基线：`pmd-aux-predict/`（23 文件全量，注入 `lib/` 全部 jar）；JSP：`pmd-jsp-baseline/` + scriptlet 复现 |
+| 比对键 | 规则名 + 行号（多重集合比对，容忍同规则同行多次） |
+| classpath 口径 | 3 个复测文件以 aux 基线比对（插件 Maven 解析输出与 lib/ jar 列表等价）；其余 20 个文件经 aux 基线核验无差异；`DesignErrorProne` 在 aux 下多 1 条 `UseCorrectExceptionLogging`（763），报告为复测前的 762 条版本，两轮各自与对应基线一致，不影响覆盖结论 |
+| 已知口径差异 | 工程自带演示说明中的部分文件（如 `SecurityDemo.jsp` 注释期望的 JSP security 规则）不在规则集内，属演示注释与规则集的口径差 |
+| ESLint 条目 | JSP 报告中 6 条 `eslint:` 前缀条目来自 ESLint 适配器（层 3），不计入 PMD 规则覆盖口径；行号映射逻辑已验证 |
+
+---
+
+## 八、结论与后续
+
+**demo-pmd 工程的插件实测验证完成，达成全覆盖**：
+
+1. ✅ 插件行为零偏差（1813/1813 逐条一致，26/26 文件，含 classpath 修复后的复测轮）
+2. ✅ 规则覆盖：Java 269/269（100%，7/7 类满覆盖）+ JSP 10/10（100%）= **279/279 全覆盖**
+3. ✅ JSP 三层分析架构（JSP 规则集 + scriptlet 包装 + ESLint）完整验证，行号映射零误差
+4. ✅ 辅助 classpath 自动解析链路（Maven `dependency:build-classpath` → PMD aux classpath）实测打通
+5. ✅ 容错路径验证（AI 超时自动降级，静态结果不受影响）
+6. ✅ 额外收获：发现并修复 Windows 下 `spawn mvnw.cmd` 抛 `EINVAL` 的插件缺陷（影响全部 Windows 用户的依赖解析）

 4. ✅ 「内置配置回退」路径验证通过（工程无 `.sqlfluff` 配置文件场景）
 
-**后续建议**：
-
-- ~~插件侧修复 JJ01~~（✅ 已完成并验证）
-- **其他工程**：`demo-pmd` 按同样方法实测（先本地基线复现 → 实测逐条比对），注意 Java 版本与 ruleset
-- **可选**：若需验证「工程配置优先」路径，可在工程根添加 `.sqlfluff` 配置文件复测（预期插件改用工程配置）

 3. ✅ 「内置配置回退」路径完整验证（工程无 `.stylelintrc` 场景）
 4. ✅ 零缺陷（对照 SQLFlutt 发现的 JJ01 NaN 问题，Stylelint 适配器的 endLine 回退写法正确）
 
-**实测进度总览**（四个 demo 工程）：
-
-| 工程 | 实测状态 | 结果 |
-|---|---|---|
-| demo-eslint | ✅ 完成 | 126/126 种 · 292/292 条逐条一致 |
-| demo-sqlfluff | ✅ 完成 | 57/57 种 · 113 处（112 条零偏差 + JJ01 行号显示缺陷） |
-| demo-stylelint | ✅ 完成 | **68/68 种 · 145/145 条逐条零偏差** |
-| demo-pmd | ⏳ 待实测 | 预期 281 条规则（Java 269 + JSP 12），注意 Java 版本与 ruleset |
-
-**后续建议**：仅剩 `demo-pmd` 待实测——测试机需 JDK 8+（插件用 PmdRunner.class 直跑，无沙箱 JDK 11 限制），打开 Java/JSP 样例文件后与预期基线比对即可，全套四工程验证收官。
