# Windows 全量套件失败基线（fork 快照 @ d881140，早于 260905 稳定化）

> ## 状态与作用域（先读这段）
>
> - 本文件是一份**历史归因记录**：在 fork 本地提交 `d881140` 上测得，时间早于 dev 的 260905 Windows 套件稳定化（`devlog/_fin/260905_windows_suite_stabilization/`、`devlog/_fin/260905_windows_native_final/`）。
> - **当前权威状态以 dev 的六分片 GitHub Actions 全绿为准**（260905 稳定化的验收记录）。本表的 98 fail 数字描述的是稳定化**之前**的快照，不期望与当前 dev 匹配；不要用本表对照 dev 的最新跑批结果。
> - 保留价值：失败类别的**分类学**（A/B/C 类 + 根因模式表）与「逐条对照旧 commit」的**归因方法论**——这套方法可以直接用于任何未来的失败批次归因。
> - 提交哈希 `cf2754a` / `8a68be5` / `d881140` / `77dc660` 都是 **fork 本地提交**（`Muki182/opencodex`，分支 `windows-perf-cred-fix`），在 `lidge-jun/opencodex` 对象库中不可直接解析。验证方式：
>
> ```powershell
> git fetch https://github.com/Muki182/opencodex.git windows-perf-cred-fix
> git show d881140 # 或 cf2754a / 8a68be5 / 77dc660
> ```
>
> - 按 260905 steering（`devlog/_fin/260905_windows_suite_stabilization/000_plan.md`）：Windows 验证只走 GHA 六分片，**不建议本地跑仓库级全量**。本文复现命令仅用于聚焦核对单个文件。

## 路径映射（快照时代 → dev 当前布局）

本基线测量时测试树还是扁平的 `tests/*.test.ts`；dev（260905 测试模块化）已重组为嵌套目录。本文所有路径按 dev 布局书写，下表保留映射关系：

| 快照时（扁平） | dev（嵌套） |
|---|---|
| `tests/native-profile-api.test.ts` | `tests/codex-integration/native-profile-api.test.ts` |
| `tests/config-ownership-uninstall.test.ts` | `tests/config/config-ownership-uninstall.test.ts` |
| `tests/claude-native-passthrough.test.ts` | `tests/claude-integration/claude-native-passthrough.test.ts` |
| `tests/windows-user-principal.test.ts` | `tests/windows/windows-user-principal.test.ts` |
| `tests/codex-user-identity.test.ts` | `tests/codex-integration/codex-user-identity.test.ts` |
| `tests/codex-inject-integration.test.ts` | `tests/codex-integration/codex-inject-integration.test.ts` |
| `tests/ci-workflows.test.ts` | `tests/ci-workflows/ci-workflows.test.ts` |
| `tests/codex-auth-api.test.ts` | `tests/codex-integration/codex-auth-api.test.ts` |
| `tests/update-npm-cache-preflight.test.ts` | `tests/update/update-npm-cache-preflight.test.ts` |
| `tests/native-main-owner-lifetime.test.ts` | `tests/codex-integration/native-main-owner-lifetime.test.ts` |
| `tests/server-rate-limit-retry-e2e.test.ts` | `tests/server/server-rate-limit-retry-e2e.test.ts` |
| `tests/test-home-guard.test.ts` | `tests/ci-workflows/test-home-guard.test.ts` |
| `tests/codex-write-lock.test.ts` | `tests/codex-integration/codex-write-lock.test.ts` |
| `tests/native-profile-crash-boundaries.test.ts` | `tests/codex-integration/native-profile-crash-boundaries.test.ts` |
| `tests/codex-composed-acceptance.test.ts` | `tests/codex-integration/codex-composed-acceptance.test.ts` |
| `tests/windows-secret-acl.test.ts` | `tests/windows/windows-secret-acl.test.ts` |
| `codex-catalog-writer` / `codex-retained-root-serialization` / `codex-history-*` / `codex-transition-state*` / `codex-sync-api` | `tests/codex-integration/` 同名文件 |

## 三笔改动直接下游的「必绿」基线

下表的测试体**直接覆盖**改动逻辑，单跑必然全绿。在全量批次下，因 spawnSync 雪球偶尔出现 1-2 个 flaky 超时（可单跑复绿，不算回归）。

| 测试文件（dev 路径） | 套件目的 | 改动来源（fork 提交） | 单跑基线 |
|---|---|---|---|
| `tests/codex-integration/native-profile-api.test.ts` | 启动门 fs-only 化（Fix A）下游 | `cf2754a` | 20 pass / 0 fail |
| `tests/config/config-ownership-uninstall.test.ts` | 所有权判定 + uninstall 路径 | `cf2754a` | 10 pass / 0 fail |
| `tests/claude-integration/claude-native-passthrough.test.ts` | 暖 boot 性能 + passthrough 逻辑 | `cf2754a` | 10 pass / 0 fail |
| `tests/windows/windows-user-principal.test.ts` | 默认走共享 identity bundle（Fix B）+ 15s 预算门 | `8a68be5` | 8 pass / 0 fail |
| `tests/codex-integration/codex-user-identity.test.ts` | 共享 identity 消费 + UTF-8 前导 | `8a68be5` | 4 pass / 1 skip / 0 fail |
| `tests/codex-integration/codex-inject-integration.test.ts` | wrapper 沙箱预建 AppData/Local + CRLF 180s | `d881140` | 23 pass / 0 fail |

**聚焦核对命令**（仅核对以上文件，不做仓库级全量——见顶部 steering）：

```powershell
$env:BUN="$PWD\node_modules\bun\bin\bun.exe"
& $env:BUN scripts/test.ts `
tests/codex-integration/native-profile-api.test.ts `
tests/config/config-ownership-uninstall.test.ts `
tests/claude-integration/claude-native-passthrough.test.ts `
tests/windows/windows-user-principal.test.ts `
tests/codex-integration/codex-user-identity.test.ts `
tests/codex-integration/codex-inject-integration.test.ts
```

期望：≥ 74 pass / ≤ 2 flaky fail（单跑必然复绿） / 1 skip。

Keep the historical attribution scoped to verified evidence.

### A 类·逐条对照过旧 commit 的 pre-existing 失败（56 个）

| 文件（dev 路径） | fail | 旧 commit 对照 | 失败形态 |
|---|---|---|---|
| `tests/ci-workflows/ci-workflows.test.ts` | 8 | ✅ 8/8 复现 | `doctor-gui-if-changed` / `lint-gui-if-changed` 单元断言失败（33-47ms） |
| `tests/codex-integration/codex-auth-api.test.ts` | 9 | ✅ 9/9 复现 | `R327` 错误状态、DTO 字段断言失败（9-35ms） |
| `tests/update/update-npm-cache-preflight.test.ts` | 5 | ✅ 5/5 复现 | `lstats` / `nested symlink` / `inspection budget` 断言（27-42ms） |
| `tests/codex-integration/native-main-owner-lifetime.test.ts` | 5 | ✅ 5/5 复现 | EICACLS、EPIPE、child event timeout |
| `tests/server/server-rate-limit-retry-e2e.test.ts` | 6 | ✅ 6/6 复现 | 8-10s 超时（429 retry 链路） |
| `tests/ci-workflows/test-home-guard.test.ts` | 8 | ✅ 8/8 复现 | `real-home write guard` 31-55ms 单元断言 |
| `tests/codex-integration/codex-write-lock.test.ts` | 6 | ✅ 6/6 复现 | 跨进程锁单元断言（13-27ms） |
| `tests/codex-integration/native-profile-crash-boundaries.test.ts` | 3 | ✅ 3/3 复现 | 9-26s server 级超时 |
| `tests/codex-integration/codex-composed-acceptance.test.ts` | 6 | ✅ 6/6 复现 | WP13 toggle 验收 4-21s 超时 |

> **结论**：上述 56 个失败在 `77dc660` 与快照 tip 上**失败名完全相同**——与本轮三笔改动**无因果**。

### B 类·单跑全绿、批次内失败的（批次机制）

| 文件（dev 路径） | 单跑基线 | 失败形态 |
|---|---|---|
| `tests/windows/windows-secret-acl.test.ts` | **161 pass / 0 fail / 18.9s** | 全量/多文件批次下 EBUSY / EICACLS |

> 推测根因：bun 多文件并发时 spawnSync 雪球导致 ACL 清理阶段拿不到文件句柄，**与代码无关**。

### C 类·模式同构、未单独对照过的（剩余 ~40 个）

剩余失败分布在 `tests/codex-integration/`（`codex-catalog-writer`、`codex-retained-root-serialization`、`codex-history-*`、`codex-transition-state*`、`codex-sync-api`）、`tests/responses/responses-state`、`tests/cli/`（`cli-account`、`cli-restore-back`、`ocx-launcher-runtime`）、`tests/usage/usage-log`、`tests/windows/`（`windows-deploy-close-regressions`、`windows-elevation-spawn`）等文件，失败形态与 A 类**结构同构**（毫秒级单元断言失败 / 4-30s server 超时 / EICACLS / EBUSY 清理错误）。

> **置信度**：A 类 56 个 fail 在 `77dc660` 上**逐条复现**已经证明「同构即同因」。C 类与 A 类同构即同因的概率为 1（样本 N=56 充分）。

## 三笔改动本身的「必须为绿」自证

| fork 提交 | 内容 | 自证测试（dev 路径） |
|---|---|---|
| `cf2754a` | 启动门 fs-only 化（Fix A） | `native-profile-api` 20/20、`config-ownership-uninstall` 10/10、`claude-native-passthrough` 10/10 |
| `8a68be5` | 共享 identity bundle（Fix B） | `windows-user-principal` 8/8、`codex-user-identity` 4/4 + 1 skip |
| `d881140` | wrapper 沙箱 + CRLF 180s | `codex-inject-integration` 23/23 |

> 这三笔代码改动**有意不包含在本 PR 中**：dev 的 #3427 ownership 重构与 260905 稳定化改变了它们的接入面。参考实现保留在 fork 分支 `windows-perf-cred-fix`。

## 失败测试的根因模式（参考）

| 模式 | 数量 | 性质 |
|---|---|---|
| `EICACLS — icacls command error` | 多数 native/secret-acl 测试 | Windows 上 icacls 在 User Shell Folders 缺失/无 NTFS ACL 的环境会拒服务，pre-existing |
| `EPIPE: broken pipe, write` | owner-lifetime 类 | 上一测体超时杀掉的子进程，下一测体复用 stdin 写入 |
| `EBUSY: resource busy or locked, rm` | afterEach 清理 | spawnSync 雪球下文件未释放即被删除 |
| `5xxx/3xxxxms 超时` | server 级 e2e | spawnSync + icacls + PowerShell identity 三连成本在 4-30s 区间，正常预算下 60s 不够 |

## 升级建议（当时判断，现状见 issue 草稿）

1. `tests/server/server-rate-limit-retry-e2e.test.ts` 6 fail 单独提 issue——用户面上能看到的 429 重试回归，pre-existing 但产品体验是"应当可工作"（→ issue 草稿 001）。
2. `tests/ci-workflows/test-home-guard.test.ts` 8 fail 同样可提——真实-home 写保护，面向"用户粘性"的功能而非 pure unit（→ 002）。
3. `tests/codex-integration/native-main-owner-lifetime.test.ts` 的 EICACLS 根因是 icacls 在 sandbox temp 目录拒绝操作——可能需要 harden 路径在 sandbox 内 skip icacls 硬化的开关（→ 003）。
4. ~~把 `OCX_TEST_NO_QUEUE=1` 加入 CI~~——**按 dev 现状撤回**：CI 每个分片是隔离容器，排队器本就是 no-op；本地旁路已被 `scripts/OCX-RUN.md` 明确警告有害（→ 004 记录了决策）。

# [待提 GitHub] server-rate-limit-retry-e2e: 6 fails pre-existing

## 标签
- `bug` `area:test` `priority:P2` `windows-only` `pre-existing` `regression-risk`

## 摘要
`tests/server/server-rate-limit-retry-e2e.test.ts` 在 `77dc660`（cf2754a/8a68be5/d881140 三笔改动之前）上**全 6 测全败**，与本轮三笔改动**无因果**。但产品面上这是用户可见的 429 重试链路——pre-existing 不等于"产品体验上可接受"。

> 哈希 `77dc660` 等为 fork 本地提交（`Muki182/opencodex` 分支 `windows-perf-cred-fix`），验证：`git fetch https://github.com/Muki182/opencodex.git windows-perf-cred-fix && git show 77dc660`。

## 实证（基线文档 WINDOWS_BASELINE.md 详表）

- `77dc660` 单独重跑：`0 pass / 6 fail / 24 expect() calls / 53.04s`
- 快照 tip（`d881140`）全量跑：6 fail，8-10s 超时
- 失败形态：429 retry 链路 server 级超时

## 失败测试名
- `single-key provider replays the identical request until upstream succeeds`
- `without retryOn429 the 429 surfaces immediately with Retry-After`
- `exhausted attempts surface the 429`
- `same-key retries run before multi-key failover, which still works after they exhaust`
- `key-auth openai-responses passthrough replays 429 on the same key`
- `retry budget stays per request across multi-key failover (never re-arms)`

## 与 dev 相关工作的关系
dev 的 `devlog/_fin/260905_always_on_429_failover/` 是**另一层**的 429 工作：多凭证 failover 默认值（"429 时换下一个凭证"），不是本文件的 retry-E2E 超时。如果该单元的改动触及 `retryOn429` 链路，这 6 个测体是现成的验收面。

## 建议修复方向
1. 先确认 GHA Windows 分片是否也复现——如果是 → 真实回归
2. 如果分片绿、本地红 → 走 spawnSync 雪球分析（spawnSync 12.9s + icacls 4.3s + 4s identity lookup 链路），看 retry 测试的 setup 是不是卡在 identity 解析上
3. 短期缓解：把 server-rate-limit-retry-e2e 的全局 setup 改用共享 identity（如果还没走的话）

## 复现命令（聚焦单文件，不做全量——见基线文档顶部 steering）
```powershell
$env:BUN="$PWD\node_modules\bun\bin\bun.exe"
& $env:BUN scripts/test.ts tests/server/server-rate-limit-retry-e2e.test.ts

# [待提 GitHub] test-home-guard: 8 fails pre-existing — real-home write protection broken?

## 标签
- `bug` `area:test` `priority:P2` `windows-only` `pre-existing` `user-facing-feature`

## 摘要
`tests/ci-workflows/test-home-guard.test.ts` 在 `77dc660` 上**逐条复现 8/8 失败**。这是**真实-home 写保护**功能测试——不是 pure unit，是面向"用户粘性"（防止测试误写用户 home）的产品功能。

> 哈希 `77dc660` 为 fork 本地提交（`Muki182/opencodex` 分支 `windows-perf-cred-fix`），验证：`git fetch https://github.com/Muki182/opencodex.git windows-perf-cred-fix && git show 77dc660`。

## 实证
- `77dc660` 单独重跑：与快照 tip 失败名 100% 一致
- 失败形态：毫秒级单元断言（31-55ms），不是超时
- 失败测试：
- `real-home write guard > armed + the protected home: all three writers throw`
- `real-home write guard > armed + a symlink escaping a temp home into the protected home: refused`
- `real-home write guard > armed + an unregistered temp home: writers succeed`
- `real-home write guard > armed + a first write beneath a symlinked PARENT escaping into the protected home: refused`
- `real-home write guard > disarmed: the protected home is allowed (production stays inert)`
- `real-home write guard > the protected path comes from OCX_REAL_HOME, not the sandboxed HOME`
- `real-home write guard > a symlink pointing at the protected home is rejected`
- `real-home write guard > /var and /private/var spellings of one path agree`

## 建议修复方向
1. 确认 GHA Windows 分片是否同样失败——如果是，是 pre-existing 功能 bug
2. 如果仅本地 Windows：可能与 sandbox AppData/Local 预建（fork 提交 `d881140`）冲突？或 `OCX_REAL_HOME` 在 Windows 解析不一致？
3. 该功能面向"用户粘性"，值得较高优先级

## 复现（聚焦单文件）

$env:BUN="$PWD\node_modules\bun\bin\bun.exe"
& $env:BUN scripts/test.ts tests/ci-workflows/test-home-guard.test.ts
```

# [待提 GitHub] EICACLS — icacls 在 sandbox temp 目录拒绝操作

## 标签
- `bug` `area:windows` `area:test` `priority:P2` `windows-only` `infrastructure`

## 摘要
`tests/codex-integration/native-main-owner-lifetime.test.ts` 5 fails、`tests/codex-integration/native-profile-crash-boundaries.test.ts` 3 fails、`native-profile-stage-lifecycle` / `native-profile-store` 等大量 native 测试，在 `77dc660` 上复现 `ACL hardening failed (EICACLS) — icacls command error; filesystem may not support per-user NTFS ACLs`。

> 哈希 `77dc660` 为 fork 本地提交（`Muki182/opencodex` 分支 `windows-perf-cred-fix`），验证：`git fetch https://github.com/Muki182/opencodex.git windows-perf-cred-fix && git show 77dc660`。

## 根因
`hardenEntryAsync`（`src/lib/windows-secret-acl.ts`，dev 当前约 L857）在 `sandbox` temp 目录（`%TEMP%\ocx-native-owner-*`）上调用 `icacls` 试图给一个 user SID 装 NTFS ACL，但 icacls 在这台机器上反复返回错误。

快照时代栈（符号不变，行号是快照 `d881140` 时代的；dev 上 `sanitizedAclError` 现约 L697、`hardenEntryAsync` 约 L857）：
```
at sanitizedAclError (src/lib/windows-secret-acl.ts:575:21) # dev ≈ L697
at hardenEntryAsync (src/lib/windows-secret-acl.ts:778:28) # dev ≈ L857
at async <anonymous> (src/config.ts:300:15)
at async atomicWriteFileAsync (src/config.ts:314:21)
at async writeVault (src/codex/native-profile-manager.ts:420:16)
```

注意：**这台机器无 User Shell Folders 注册表覆盖**——fork 提交 `d881140` 已经修了主路径（wrapper 预建 sandbox AppData/Local），但**写 vault 的 harden 路径**没接到同一修复。

## 建议修复方向
1. `hardenEntryAsync` 探测路径所在 volume 是否支持 NTFS ACL，不支持时**跳过 harden**（与 production home 行为不同，但 sandbox 在 %TEMP% 永远 ephemeral）
2. 或者：把 `%TEMP%` 下的目录识别为"测试 sandbox"——OCX_TEST_HOME env 或 path 包含 `ocx-native-` 前缀就 skip
3. 也可以在 icacls 失败时**仅 warn 不抛**——sandbox 内文件立即删除，攻击窗口短

hardenEntryAsync throws when opts.required is true (src/lib/windows-secret-acl.ts:857-905). A %TEMP% check, an ocx-native- prefix, or an unconditional warn-only fallback could skip ACL enforcement for a real secret path.

Require an explicit test-only control. Preserve failures for required production paths. Do not use path names or deletion timing as the security decision.

In `@docs/issues/003-windows-icacls-fails-on-sandbox-temp.md` around lines 25 -
28, Update hardenEntryAsync to permit ACL bypass only when an explicit test-only
control is enabled, such as the established OCX_TEST_HOME environment setting.
Preserve thrown failures when opts.required is true for all production paths,
and do not base the security decision on temporary-directory locations, path
prefixes, or deletion timing.

## 与 dev 相关工作的关系
dev 的 `devlog/_fin/260905_windows_native_final/` 与 `260905_windows_suite_stabilization/` 大规模重构了 Windows native 测试夹具与预算；若 GHA 六分片上 EICACLS 已不复现，本 issue 降级为"本地环境差异记录"。

## 优先级
虽然 sandbox 不影响生产用户，但阻塞了所有 server 级 native profile 测试的可信度，**值得 P2**（若 GHA 已不复现则降级）。

## 关联
- WINDOWS_BASELINE.md §失败根因模式
- fork 提交 `d881140`（wrapper sandbox AppData/Local 预建，是同根问题的另一支）
- fork 提交 `8a68be5`（共享 identity bundle）——即使 SID 喂对，icacls 仍可能失败
