fix(core): confirm read-only git commands when repo config executes programs (#8575) - #8645
Merged
Merged
Conversation
…rograms (#8575) Whitelisted read-only git sub-commands (status, diff, log, show, ...) are auto-approved based purely on command text, but git can execute programs configured in the repository-local config while running them: diff.external, core.fsmonitor, core.pager / pager overrides, diff driver textconv, core.askpass, credential.helper, core.sshCommand, remote proxies, ext:: remote URLs, gpg.program. A planted .git/config could turn an auto-approved command into arbitrary code execution. Add a synchronous repo-local config probe (bounded stat walk + small file reads, fail-closed) shared by the AST and regex classifiers: when a git command would classify as read-only and the repo-local config reachable from the execution cwd contains program-executing keys, the verdict is downgraded so the command requires confirmation. Global/system config is deliberately out of scope (the user's own setup, not a cloned-repo attack surface). All permission entry points (shell tool, monitor tool, permission manager, memory-scoped agent policy) now pass the execution cwd to the classifier. Classifier APIs only gain an optional parameter; behavior without cwd is unchanged.

- Speculation gate now receives the execution cwd: speculated shell calls bypass the permission flow, so evaluateToolCall passes cwd (and the shell directory arg, which takes precedence) into classifyShellCommandSafety. A speculated `git diff` in a repo with diff.external planted now hits the boundary instead of executing. - Probe reads `.git/config.worktree` of the main checkout too — with extensions.worktreeConfig enabled git reads it for the main worktree, so a key planted there no longer bypasses the probe. - plan-mode shell policy passes its effective cwd to the classifier for consistent classification (no execution hole there; consistency). - Document bare repos as out of scope. - Add end-to-end integration test driving the real probe + classifier through ShellToolInvocation.getDefaultPermission (no fs mocking).

Follow-up security audit fixes are pushed in
Verification on the pushed tree: 91 focused tests passed ( @qwen-code /triage |
Round-3 hardening of the config probe, closing bypasses found in local security review (all empirically reachable via attacker-written .git/config): - Section headers the minimal parser cannot interpret (e.g. `]` inside a quoted subsection) now fail closed instead of silently dropping the entries beneath them. - Inline `[section] key = value` lines are parsed instead of discarded. - Unparseable `.git` pointer files fail closed like unreadable ones. - include/includeIf entries are flagged rather than resolved: their targets can live outside `.git` (e.g. tracked working-tree files). - core.gitProxy added to the program-valued keys (git:// transport via whitelisted `git remote show`). - Document the cd-into-another-repo limitation in the module doc. - Add the missing PermissionManager cwd-threading contract test (dirty repo config → ask, clean → allow) and regression tests for each behavior above.

Complementing
Verification on the pushed tree: 1965 tests across the 11 affected suites pass; core typecheck, ESLint, and Prettier clean. Deliberately not done (assessed and rejected): per-call probe memoization (bounded cost, only on the auto-approve path) and a gitdir-pointer path-containment check (the probe reads exactly what git reads, so pointer redirection is not a bypass). @qwen-code /triage 中文说明作为

…8575) Round-4 hardening from the local security/correctness review — each item was empirically demonstrated against the prior head: - Compound commands now track cd/pushd/popd: statically resolvable targets move the probe's base directory (same-repo `cd subdir` stays read-only), unresolvable targets (`cd`, `cd -`, `cd $VAR`, `popd`, quoted/expanded targets) downgrade later git segments. Closes the `cd <dirty-repo> && git status` bypass in both the AST and regex classifiers, including tree-sitter's nested-list chains. - filter.<name>.clean/smudge/process flagged: `git diff` runs worktree content through the configured clean filter with no extra flags. - url.<base>.insteadOf rewrite targets starting with ext:: flagged (combined with protocol.ext.allow in the same file this executes on whitelisted `git remote show`). - Config reads are size-capped at 1 MiB and fail closed above it (DoS guard for the synchronous permission path). - Boolean pager overrides (pager.<cmd> = true/false) no longer flagged. - Added the missing wiring contract tests: PermissionManager config.getCwd() fallback, memory-scoped agent shell policy, plan-mode shell policy (including the directory-param override).

本 PR 引入的 CI 失败：Test (ubuntu-latest, Node 22.x) 红，阻塞合并。
位置
packages/core/src/followup/speculation.ts:302—— 本 PR 新增的config.getTargetDir()。packages/core/src/followup/speculation.test.ts中 6 处 mock config（第 60 / 124 / 184 / 245 / 308 / 371 行）只提供getCwd，全文件getTargetDir出现 0 次。
触发条件
runSpeculativeLoop 处理 functionCalls 时对 mock config 调用 getTargetDir() → TypeError: config.getTargetDir is not a function。异常冒泡到 speculation.ts:187 的 .catch()，在第 190 行把 state.status 置为 'aborted'。
影响
speculation.test.ts 的 7 个用例全部失败，报错形态一致（expected 'aborted' to be 'completed' / 'boundary'）：
FAIL src/followup/speculation.test.ts > startSpeculation > stops at a boundary when the host guard denies a speculative invocation
AssertionError: expected 'aborted' to be 'boundary'
...
Tests 7 failed | 19348 passed | 10 skipped
不是偶发、也不是既有失败：
- 前一个 head
b1ff1e42同样红，7 个用例完全相同（job 92730679338）；当前 head615e2253同样红（job 92744514670）。 main（a3a840be2）的speculation.ts里没有getTargetDir调用，该文件的失败只来自本 PR。
上一轮 autofix 报告里「CI 的 ubuntu 失败是 packages/cli 的 kitty protocol，与本 PR 无关」已不适用于当前 head —— 现在的失败在 packages/core，且由本 PR 这一行直接导致。
修复方向
二选一：
- 给上述 6 处 mock config 补
getTargetDir: vi.fn().mockReturnValue(process.cwd())； - 或在
speculation.ts:302改为config.getTargetDir?.() ?? config.getCwd()，顺带让探针在缺少 target dir 的宿主上不炸。
方案 1 更贴合本 PR 的意图（生产 Config 一定有 getTargetDir）；若选方案 2，仍建议补 mock 以保证探针 cwd 被真正断言到。

…8575) Address review round 1 findings on the repository-local git config execution probe: - Track cd/pushd across every sibling-statement sequence (program, brace group, subshell body), not only `&&` lists; propagate the directory out of brace groups and redirected/negated wrappers. - Respect list-operator semantics: cd state no longer leaks across `||` or `&`, and non-`&&` sequential statements keep the prior directory in the safety equation. - Resolve cd targets strictly: skip flag arguments (`-P`/`-L`/`-e`/`--`), reject flag-only and multi-operand forms, accept only statically unquotable word/string/raw_string targets (no concatenation, ANSI-C quoting, backslash escapes, or expansions), and fail closed when the target is missing or not a directory. - Probe git discovery more faithfully: resolve symlinks (realpath), treat a directory that is itself a git directory (bare repos, submodule storage) as a repo, fail closed when the search-depth budget exhausts, decode config values and subsections the way git does (quoted-segment concatenation, escapes), and add diff.<driver>.command and core.alternateRefsCommand to the program-valued keys. - Scope fixes: fall back to the scoped execution root when the memory agent shell probe has no cwd; resolve compound-command defaults against the full command so a segment rule cannot override the cd-aware verdict; keep sub-commands after a directory change in the confirmation scope for both the shell and monitor tools. - Tests: regression coverage for every fix plus mutation-checked wiring tests; skip the chmod-based EACCES simulation on Windows/root; use a relative submodule gitdir pointer; parametrize filter clean/smudge/process.

Maintainer verification: real local environment, real git, real TUII rebuilt both sides from source and verified this PR end-to-end against real Setup
1. Ground truth: does real git actually execute, and does the classifier agree?For each config vector I planted it in a fresh repo, ran the whitelisted read-only sub-command with real git, and recorded whether the configured program actually ran (marker file). Then I classified the same Every configured program is an executable script file, so git's config-value quoting cannot mangle it.
¹ already downgraded on base — Result: 19/19 vectors that real git actually executes are downgraded; 18 of them were silently auto-approved before this PR. All 6 negative controls still auto-approve — no new friction on clean repos. Both classifier paths (tree-sitter AST and the regex fallback) agree on every case. 2. Adversarial compound commands (the
|
| Command | cwd | Real exec | base AST | PR AST |
|---|---|---|---|---|
cd <dirty> && git diff |
plain | ✅ | allow | ask |
cd <dirty>; git diff |
plain | ✅ | allow | ask |
(cd <dirty> && git diff) |
plain | ✅ | allow | ask |
cd dirty && git diff (relative) |
lab root | ✅ | allow | ask |
cd sub && git diff (same repo) |
dirty | ✅ | allow | ask |
cd <clean> && cd - && git diff |
dirty | ✅ | allow | ask |
{ cd <dirty>; git diff; } |
plain | ✅ | allow | ask |
git status | head -3 |
dirty | ✅ | allow | ask |
echo hi && git diff / false || git diff |
dirty | ✅ | allow | ask |
GIT_DIR=<dirty>/.git … git diff |
clean | ✅ | ask | ask |
GIT_CONFIG_COUNT=1 … git diff |
clean | ✅ | ask | ask |
git -C <dirty> diff / git --git-dir=… diff |
clean | ✅ | ask | ask |
cd <clean> && git diff |
dirty | ❌ | allow | allow ✅ |
cd <plain> && ls -la |
dirty | ❌ | allow | allow ✅ |
cd <dirty> & git diff |
plain | ❌ | allow | allow ✅ |
cd $TARGET && git diff |
plain | ❌ | allow | ask (fail-closed) |
No gaps: every compound that really executed the planted program is downgraded, and the "cd out of a dirty repo into a clean one" case correctly stays auto-approved.
3. End-to-end in the real TUI (default / Ask-permissions mode)
Victim repo with [diff] external = ./evil.sh; identical scripted tool call on both sides.
Base — silently auto-executed, attacker script ran (fatal: external diff died is evil.sh exiting non-zero after dropping its marker):
PR — confirmation required, marker never created:
PR, clean repo — git diff still auto-approves silently (no regression):
PR, dirty repo but a non-git command — ls -la unaffected:
4. AUTO mode (the shipped default) — residual gap worth a follow-up
Same scenario with tools.approvalMode: auto, counting requests to the model server:
| Build | AUTO classifier calls | Outcome |
|---|---|---|
| base | 0 | executed silently, attacker script ran |
| PR, scripted classifier says allow | 1 | executed — attacker script ran |
| PR, scripted classifier says block | 2 | blocked |
So in AUTO mode the probe does not itself stop the attack: it converts a silent auto-approval into a decision by the AUTO LLM classifier. That classifier's prompt carries only the command text and the cwd ({"command":"git diff","cwd":"…"}) — it cannot see that the repo-local config executes a program, which is exactly the information text-side analysis is missing by construction.
Suggestion (follow-up, not a merge blocker): surface the probe's finding into the classifier context (e.g. a note that the repo-local git config contains program-executing keys), or treat probe-downgraded git calls as not auto-approvable in AUTO mode. Right now the protection is decisive in default/plan modes and advisory in AUTO.
5. Tests, performance, false positives
Tests — all 13 touched test files pass on the PR (2264 tests). Full packages/core suite on the PR: 4 failed / 19534 passed.
- 3 of the 4 fail identically on the clean base worktree (
read-file,zoom-image,memoryLifecycle.integration) — pre-existing and environment-specific, exactly as the PR describes. - The 4th,
session-writer-lease, only fails under full-suite load and passes 2/2 in isolation on the PR head; it does not touch the changed code. Load-related flake, unrelated to this PR.
Performance — probe cost per git classification (300 iterations, linked worktree so the probe reads pointer + commondir config):
| Operation | µs/op |
|---|---|
classify git status (no cwd, base behaviour) |
25 |
classify git status (cwd = repo root) |
260 |
classify git status (cwd = deep subdir) |
351 |
classify ls -la (cwd set) |
8 (probe not reached) |
Sub-millisecond, once per shell call — fine.
False positives on real repos — the probe returns false (no new prompt) for my actual working repos, including qwen-code itself which sets core.hooksPath = .husky/_ in .git/config (husky ships no post-index-change/fsmonitor-watchman, so the hooks check correctly stays quiet), and for its linked worktrees. 15 everyday commands (git status, git log, cd packages/core && git status, git status | head, …) classify identically on base and PR.
Repos that will start prompting, all intended by design but worth a release note:
git lfs install --local(writesfilter.lfs.clean/smudge/processinto.git/config) — note plaingit lfs installwrites the global config, which is deliberately not probed;- repo-local
credential.helper; repo-localcore.pager(e.g.less -FRX).
The dialog's "Always allow run 'git …' commands in this project" is a reasonable escape hatch for these.
Fail-closed paths verified for real: unreadable .git/config (chmod 000) → ask; >1 MiB config → ask; unparseable .git pointer file → ask.
Verdict
Behaviour matches the PR description on every point I could test, on both classifier paths, with no false negatives across 46 real-git cases and no measurable friction on clean repos. I'm happy to merge this, and suggest tracking the AUTO-mode delegation in §4 as a follow-up.
中文版本
维护者验证：本地真实环境 + 真实 git + 真实 TUI
我从源码重新构建了 PR 与 base 两套环境，用真实 git 和真实 CLI 做了端到端验证（不只是单测）。结论：漏洞在 base 上复现，修复覆盖了我能真正触发的全部执行向量，没有发现漏判。 AUTO 模式下有一个残留缺口，建议作为后续项跟进（见 §4）。
环境
| 项 | 值 |
|---|---|
| PR head | bb6000ca73（fix/8575-git-config-exec-probe） |
| Base | 63a8ed4338（与 origin/main 的 merge-base） |
| 构建 | 两个 worktree 均 npm ci && npm run build && npm run bundle → 真实 dist/cli.js（已确认探针代码进入 dist/chunks/） |
| 环境 | macOS（Darwin 25.6.0，Apple Silicon），Node v24.18.1，git 2.55.0 |
| 模型 | 脚本化的 OpenAI 兼容 SSE 服务，固定发出一次 run_shell_command 工具调用，保证两侧输入完全一致 |
1. 基准事实：真实 git 到底执不执行，分类器判得对不对
每个配置向量都植入全新仓库，用真实 git 跑对应的只读子命令，记录被配置的程序是否真的执行（标记文件）；再用同一组 (命令, cwd) 在 base 与 PR 上跑两条分类路径。
所有被配置的程序都写成可执行脚本文件，避免 git 配置值的引号解析把命令弄坏。

— | ❌ | 放行 | 放行 ✅ | 放行 ✅ |
¹ base 上本就已降级——--show-signature 在 helper 选项名单里。
² 保守的过度近似，与 PR 描述一致。
结论：真实 git 会执行的 19 个向量全部被降级，其中 18 个在本 PR 之前是静默自动放行的；6 个负控制仍然自动放行——干净仓库没有新增摩擦。 两条分类路径（tree-sitter AST 与正则回退）在每个用例上判定一致。
2. 对抗性复合命令（验证 cd 追踪）
同样方法——先用 bash -c 在给定 cwd 真实执行，再做分类。dirty = 植入 diff.external+core.fsmonitor 的仓库，clean = 普通仓库，plain = 非仓库目录。
| 命令 | cwd | 真实执行 | base AST | PR AST |
|---|---|---|---|---|
cd <dirty> && git diff |
plain | ✅ | 放行 | 确认 |
cd <dirty>; git diff |
plain | ✅ | 放行 | 确认 |
(cd <dirty> && git diff) |
plain | ✅ | 放行 | 确认 |
cd dirty && git diff（相对路径） |
lab 根 | ✅ | 放行 | 确认 |
cd sub && git diff（同仓库） |
dirty | ✅ | 放行 | 确认 |
cd <clean> && cd - && git diff |
dirty | ✅ | 放行 | 确认 |
{ cd <dirty>; git diff; } |
plain | ✅ | 放行 | 确认 |
git status | head -3 |
dirty | ✅ | 放行 | 确认 |
echo hi && git diff / false || git diff |
dirty | ✅ | 放行 | 确认 |
GIT_DIR=<dirty>/.git … git diff |
clean | ✅ | 确认 | 确认 |
GIT_CONFIG_COUNT=1 … git diff |
clean | ✅ | 确认 | 确认 |
git -C <dirty> diff / git --git-dir=… diff |
clean | ✅ | 确认 | 确认 |
cd <clean> && git diff |
dirty | ❌ | 放行 | 放行 ✅ |
cd <plain> && ls -la |
dirty | ❌ | 放行 | 放行 ✅ |
cd <dirty> & git diff |
plain | ❌ | 放行 | 放行 ✅ |
cd $TARGET && git diff |
plain | ❌ | 放行 | 确认（失败即收紧） |
没有缺口：真正执行了植入程序的复合命令全部被降级；"从脏仓库 cd 到干净仓库"的情形正确地保持自动放行。
3. 真实 TUI 端到端（default / 询问权限模式）
受害仓库 .git/config 含 [diff] external = ./evil.sh，两侧的脚本化工具调用完全相同。
Base——静默自动执行，攻击脚本真的跑了（fatal: external diff died 正是 evil.sh 落下标记后非零退出）：
PR——要求确认，标记文件始终没有生成：
PR + 干净仓库——git diff 仍然静默自动放行（无回归）：
PR + 脏仓库但非 git 命令——ls -la 不受影响：
4. AUTO 模式（发布默认值）——值得跟进的残留缺口
同样场景设 tools.approvalMode: auto，统计到模型服务的请求数：
| 构建 | AUTO 分类器调用 | 结果 |
|---|---|---|
| base | 0 | 静默执行，攻击脚本运行 |
| PR，脚本化分类器判 allow | 1 | 执行了——攻击脚本运行 |
| PR，脚本化分类器判 block | 2 | 被拦截 |
也就是说 AUTO 模式下探针本身并不能阻断攻击：它把"静默自动放行"变成了"交给 AUTO LLM 分类器裁决"。而该分类器的提示里只有命令文本和 cwd（{"command":"git diff","cwd":"…"}），看不到仓库本地配置会执行程序——这正是文本侧分析在原理上缺失的信息。
建议（后续项，不阻塞合并）： 把探针结论带进分类器上下文（例如提示"该仓库本地 git 配置含可执行键"），或者让被探针降级的 git 调用在 AUTO 模式下不可自动放行。目前这层防护在 default/plan 模式是决定性的，在 AUTO 模式是提示性的。
5. 测试、性能、误报
测试——PR 上 13 个改动相关测试文件全绿（2264 个用例）。packages/core 全量：4 失败 / 19534 通过。
- 其中 3 个在干净 base worktree 上同样失败（
read-file、zoom-image、memoryLifecycle.integration），是预先存在的环境相关失败，与 PR 描述一致。 - 第 4 个
session-writer-lease只在全量并发下失败，在 PR head 上单独跑 2/2 通过，且不涉及改动代码。属负载相关抖动，与本 PR 无关。
性能——每次 git 分类的探针开销（300 次迭代；这是链接 worktree，探针要读指针 + commondir 配置）：
| 操作 | µs/次 |
|---|---|
分类 git status（不传 cwd，即 base 行为） |
25 |
分类 git status（cwd = 仓库根） |
260 |
分类 git status（cwd = 深层子目录） |
351 |
分类 ls -la（传 cwd） |
8（不触发探针） |
亚毫秒级、每次 shell 调用一次，没问题。
真实仓库误报——对我实际在用的仓库探针都返回 false（不会新增确认框），包括 qwen-code 本身（其 .git/config 设了 core.hooksPath = .husky/_；husky 不提供 post-index-change/fsmonitor-watchman，所以 hooks 检查正确保持沉默），以及它的链接 worktree。15 条日常命令（git status、git log、cd packages/core && git status、git status | head 等）在 base 与 PR 上判定完全一致。
确实会开始弹确认框的仓库（都是设计预期，但值得写进发布说明）：
- 用
git lfs install --local的仓库（会把filter.lfs.clean/smudge/process写进.git/config）——注意普通的git lfs install写的是全局配置，而全局配置是刻意不探测的； - 在仓库本地设了
credential.helper的；仓库本地设了core.pager（如less -FRX）的。
确认框里的"始终允许本项目执行 'git …' 命令"是这些场景合理的豁免出口。
失败即收紧路径均已实测：.git/config 不可读（chmod 000）→ 确认；配置大于 1 MiB → 确认；.git 指针文件无法解析 → 确认。
结论
我能测到的每一点行为都与 PR 描述相符，两条分类路径一致，46 个真实 git 用例无漏判，干净仓库无可测量的摩擦。我同意合并，并建议把 §4 的 AUTO 模式委派作为后续项跟踪。

There was a problem hiding this comment.
Approving — reviewed at 8000fafd7b. C=0 (42/42 Critical and 25/25 Suggestion threads resolved).
Worth stating up front: this is effectively a different PR from the one I approved on c2fc8b3fad, and that approval was correctly dismissed. The diff went from +3897/−111 across 23 files to +349/−24 across 13, and refactor(core): reset git config probe to issue scope is why. My prior verification is void, so this is a fresh pass.
The redesign is the right call, and it deletes a whole bug class
The old approach hand-rolled a 777-line git-config parser. Reviewing that meant verifying escape decoding, subsection \<char> semantics, key case-folding, commondir, gitfile redirects, per-worktree admin dirs, and a search-depth cap that could fail open — I probed 48 such rows last time, and the fact that it took 48 rows is itself the argument against that design.
The new git-config-safety.ts is 84 lines that ask git:
git -C <cwd> config --includes --show-scope --null --get-regexp '^diff\.external$|^core\.fsmonitor$'
Git now owns syntax, escapes, includes, precedence and worktree scope. Every one of those 48 rows becomes git's problem rather than this repo's. That is a strictly better place to put the boundary.
Verified against real git, not assumed
The load-bearing assumption is the wire format, so I checked it on real git 2.50.1 rather than trusting the parse:
local\0core.fsmonitor\nmy-monitor\0local\0diff.external\ntouch /tmp/PWNED\0
split('\0') with fields[i]=scope, fields[i+1]=key\nvalue, stepping i += 2 while i + 1 < length, parses that exactly and correctly ignores the trailing empty field. Exit status is 0 with matches and 1 with none, which matches the status === 1 → NO_RISK branch.
Then end-to-end through getLocalGitConfigRisk against real repos — 20/20 rows correct:
| Case | Result |
|---|---|
diff.external set / core.fsmonitor = program / both |
correctly flagged |
core.fsmonitor = true,false,TRUE,yes,no,on,off,1,0 |
correctly not flagged — a boolean selects git's built-in monitor, not a program |
clean repo, unrelated keys (diff.tool, core.editor), empty diff.external |
correctly not flagged |
| directory that is not a repo, nonexistent path | correctly not flagged |
diff.external via relative [include], absolute [include], and a nested include chain |
all correctly flagged, and git reports scope local for them, so the local/worktree filter genuinely covers includes as the design doc claims |
One correction to my own work: my first pass reported the include case as a miss. That was my fixture — a relative include.path resolves against the including file's directory (.git/), not the worktree, so git itself never saw my include. Placed correctly, all three include shapes are covered.
Fail-closed is right where it matters: PROBE_FAILED = { diffExternal: true, fsmonitor: true } covers a non-zero/non-1 exit, a non-string stdout, and a malformed record with no newline; timeout: 1000 and maxBuffer: 64 KiB land there too.
Integration sites
All seven are the same small shape — thread a directory through to a new *InDirectory variant, falling back to the cwd-less one when none is known: plan-mode-shell-policy (permissionContext.cwd), speculationToolGate (args['directory'] ?? cwd), speculation (config.getTargetDir?.()), memory-scoped-agent-config (ctx.cwd ?? projectRoot), permission-manager, monitor, shell. I read each; nothing surprising.
Note the consequence rather than a defect: where no cwd is available the fallback runs no probe, so a command can still classify read-only in a repo whose config would execute a program. That is unavoidable — you cannot probe a directory you do not know — and it is the pre-PR behaviour on those paths, so it is not a regression. Worth knowing it exists.
Tests
959 pass at this commit — shellAstParser 546, permission-manager 332, monitor 81. Test (ubuntu-latest, Node 22.x) is green on this head. (review-pr shows failure, but that is the review-bot workflow, not a code test.)
One Suggestion: git-config-safety.ts ships 84 lines of security-relevant core logic with no dedicated test file — the 875-line git-config-safety.test.ts went away with the old design and nothing replaced it. Coverage is indirect via shellAstParser.test.ts (+97) and permission-manager.test.ts (+14). The behaviours most worth pinning are exactly the ones I had to establish by hand: the boolean-fsmonitor exclusion, local/worktree-only scoping, and the fail-closed branches. Those are cheap unit tests against a temp repo and they would stop a future edit from silently widening the probe.
中文说明
批准 —— 审查提交 8000fafd7b，C=0（42/42 Critical 与 25/25 Suggestion 均已解决）。
需先说明：这实际上已是与我此前在 c2fc8b3fad 上批准的那个 PR 不同的 PR，且那次批准被正确地 dismiss 了。 差异从 +3897/−111、23 文件缩减到 +349/−24、13 文件，原因是 refactor(core): reset git config probe to issue scope。我先前的验证已失效，故本次为全新审查。
这次重构方向正确，并且消灭了一整类缺陷。 旧做法手写了 777 行 git-config 解析器；审查那份代码意味着要验证转义解码、子节 \<char> 语义、键名大小写折叠、commondir、gitfile 重定向、per-worktree admin 目录，以及一个可能 fail-open 的搜索深度上限——我上次为此跑了 48 个探针用例，而"需要 48 个用例"本身就是反对那种设计的论据。新的 git-config-safety.ts 只有 84 行，改为向 git 提问（git config --includes --show-scope --null --get-regexp …）。语法、转义、include、优先级与 worktree 作用域从此由 git 负责，那 48 行关注点变成了 git 的问题而非本仓库的问题——这是更合适的边界位置。
对真实 git 验证而非假定：承重假设是输出格式，我在真实 git 2.50.1 上核对了 local\0key\nvalue\0 形态，确认按 i += 2、i + 1 < length 的配对解析完全正确且会忽略尾部空字段；有匹配时退出码 0、无匹配时 1，与 status === 1 → NO_RISK 分支一致。
随后针对真实仓库端到端跑 getLocalGitConfigRisk，20/20 全部正确：两个可复现组合被正确标记；core.fsmonitor 取 9 种布尔值（含大写 TRUE）均正确不标记（布尔值选的是 git 内建监视器而非外部程序）；干净仓库、无关键、空值均不标记；非仓库目录与不存在路径均不标记；diff.external 经相对 [include]、绝对 [include]、嵌套 include 链全部正确标记，且 git 对它们报告的 scope 是 local，因此 local/worktree 过滤确实覆盖 include，与设计文档所称一致。
对我自己的一处更正：首轮我把 include 用例报成漏判，那是我的 fixture 错了——相对 include.path 是相对包含它的配置文件所在目录（.git/）解析，而非工作区，故 git 本身就没看见我的 include。放对位置后三种 include 形态都被覆盖。
fail-closed 落在了该落的地方：非 0/1 退出码、stdout 非字符串、记录缺少换行都会走 PROBE_FAILED（两项均为 true）；timeout: 1000 与 64 KiB maxBuffer 也归入该分支。
集成点七处形态一致：把目录透传给新的 *InDirectory 变体，未知时回退到无 cwd 版本。我逐一读过，没有意外。需指出一个后果而非缺陷：无 cwd 可用时回退路径不做探测，因此命令仍可能在一个配置会执行程序的仓库中被判为只读。这无法避免（无法探测未知目录），且是这些路径改动前的既有行为，故不是回归，但值得知晓。
测试：本提交下 959 通过（shellAstParser 546、permission-manager 332、monitor 81）；Test (ubuntu-latest) 在本 head 为绿（review-pr 的失败是评审机器人工作流，非代码测试）。
一条 Suggestion：git-config-safety.ts 带着 84 行与安全相关的 core 逻辑合入，却没有专属测试文件——875 行的 git-config-safety.test.ts 随旧设计一起消失且无替代，覆盖只能间接依赖 shellAstParser.test.ts(+97) 与 permission-manager.test.ts(+14)。最值得钉住的行为恰是我手工建立的那几条：布尔 fsmonitor 排除、仅 local/worktree 作用域、以及各 fail-closed 分支。针对临时仓库写这些单测成本很低，却能阻止未来某次改动静默放宽该探测。

Semantic resolution: main's QwenLM#8645 added the directory-scoped classifyShellCommandSafetyInDirectory consumed by plan-mode-shell-policy and speculationToolGate. Apply this PR's hasShellSubstitution gate to it via a shared internal helper, mirroring isShellCommandReadOnlyInternal, so the QwenLM#8582 downgrade covers both variants.

What this PR does
This PR closes the two repository-local Git configuration execution paths reproduced in #8575:
diff.externalwhen runninggit diff, andcore.fsmonitorwhen runninggit status. Before either command is auto-approved as read-only, the classifier asks native Git for the effective included configuration at the execution directory and downgrades only the matching command/config pair. Probe and parse errors fail closed. A precedingcdorpushdalso requires confirmation instead of introducing a shell cwd simulator.Why it's needed
Command-text analysis cannot see programs selected from repository-local Git configuration. A writable or shared workspace can therefore turn an apparently read-only Git command into program execution. Native
git configis the smallest reliable source of config syntax, include, precedence, scope, and worktree semantics.Reviewer Test Plan

中文说明
本 PR 做了什么
本 PR 修复 #8575 已复现的两个仓库本地 Git 配置执行路径：运行
git diff时的diff.external，以及运行git status时的core.fsmonitor。在这两个命令被自动判为只读之前，分类器会让原生 Git 读取执行目录下包含 include 后的有效配置，并且只降级匹配的命令/配置组合。探针或解析失败时采用失败关闭。前面出现cd或pushd时也会要求确认，而不是引入 shell cwd 模拟器。为什么需要
命令文本分析看不到仓库本地 Git 配置选择的程序。可写或共享工作区因此可能把表面只读的 Git 命令变成程序执行。原生
git config是覆盖配置语法、include、优先级、scope 与 worktree 语义的最小可靠来源。评审测试计划
如何验证
diff.external，确认git diff要求确认，而git status仍为只读。core.fsmonitor设置程序，确认git status要求确认，而git diff仍为只读。core.fsmonitor=false，确认git status仍为只读。cd <其他仓库> && git status会要求确认，而不是探测错误仓库。git diff --check。前后证据
N/A——权限分类器行为由临时仓库测试覆盖。
测试环境
环境（可选）
Node 22、Git 2.39.5 与 core 单元测试环境。
风险与范围
git -C或先切换目录再运行 Git 的命令已经会要求确认。关联 Issue
