Pull request overview
Adds standalone-install auto-update support so Qwen Code can update user-writable standalone installations without falling back to npm.
Changes:
- Detects standalone installs via
manifest.jsonand surfaces standalone update messaging. - Adds a standalone updater that downloads release archives, verifies SHA256, extracts, and replaces the install directory.
- Wires standalone auto-update into the existing update event flow and adds the
tardependency.

Review — standalone auto-update
Solid, security-conscious shape overall: atomic replace, stale-lock reclamation via PID liveness, checksum + (optional) Ed25519 signature, a smoke test before the swap, and OSS→GitHub fallback are all the right building blocks. A few issues I'd treat as blocking before this ships enabled-by-default, plus convention/coverage gaps.
🔴 High
1. The Windows deferred update is deleted by its own finally block — the Windows path can never succeed.
In atomicReplace (win32) the new install is staged at ${standaloneDir}.new (pendingDir) and a detached .bat is spawned that waits for this process to exit and then moves pendingDir → standaloneDir. But performStandaloneUpdate's finally runs synchronously, long before the process exits:
// standalone-update.ts:514-518
// Clean orphaned pendingDir if it exists (from a failed Windows path validation)
const pendingDir = `${standaloneDir}.new`;
if (fs.existsSync(pendingDir)) {
fs.rmSync(pendingDir, { recursive: true, force: true }); // ← deletes the staged update
}On the successful deferred path pendingDir is the live staged update, not a validation orphan, so this removes it while the .bat is still in its tasklist wait loop. When the .bat finally runs move /Y "<pendingDir>" "<standaloneDir>" the source is gone and the move silently fails (the script has no error handling). The user sees “Update downloaded, will apply after exit” but nothing is ever applied — consistent with the PR's pendingDir on the throw path, or skip this finally cleanup when result === 'deferred').
2. No effective supply-chain protection by default; the embedded signing key is a placeholder.
This runs automatically (enableAutoUpdate defaults to true) and downloads, executes (smoke test), and installs a binary. The only mandatory check is the SHA256 from SHA256SUMS, fetched from the same origin as the archive — so it guards against corruption, not a compromised mirror/release. The Ed25519 path is the real defense, but as shipped it's a no-op:
- The embedded key is explicitly a placeholder —
standalone-update-verify.ts:18(“Replace this with the production key generated by the release team”). - Verification only runs if
SHA256SUMS.sighappens to exist, and is only required whenQWEN_REQUIRE_SIGNATURE=1(undocumented, default off) —verifyChecksum,standalone-update.ts:94-113.
So by default a compromised release asset is downloaded and executed during the smoke test before any authenticity check that matters. Recommend either (a) gate standalone auto-update behind explicit opt-in until release CI signs with the real key and the signature is required by default, or (b) land the real key + CI signing in this same change and require the signature. A placeholder key gives the appearance of signature verification without the substance.
🟡 Medium
3. Silent npm → standalone migration can create a shadow install that isn't on PATH — installationInfo.ts:206-215.
When the npm prefix looks non-writable the code silently switches a global-npm user to a standalone install under ~/.local/lib/qwen-code and writes a ~/.local/bin/qwen wrapper. But nothing adds ~/.local/bin to PATH, and the existing npm qwen (e.g. /usr/local/bin) usually still wins resolution — so the user keeps running the old binary and the “update” appears to do nothing. Also npmPrefixDir = path.dirname(path.dirname(realPath)) is not the npm prefix; it's the package directory (~2 levels under wherever the bin resolves), and the depth is layout-dependent. Consider making the migration explicit (notice/prompt) rather than automatic.
4. Missing license headers — CI lint will fail.
The repo enforces eslint-plugin-license-header; every source file begins with the @license / Copyright 2025 Google LLC / SPDX-License-Identifier: Apache-2.0 block. All four new files (standalone-update.ts, standalone-update-verify.ts, and both *.test.ts) are missing it.
5. Bulk of the new code is untested; rollbackStandaloneUpdate is unreachable dead code.
standalone-update.test.ts covers only rollbackStandaloneUpdate. The risky core — performStandaloneUpdate, downloadWithFallback, verifyChecksum (incl. the *filename parsing), extractArchive, atomicReplace (especially the Windows branch with the bug above), acquireLock stale-reclaim, smokeTest — has no tests. Separately, rollbackStandaloneUpdate and the .qwen-rollback-info.json metadata reference a “/doctor rollback” that doesn't exist in this PR, and rollbackStandaloneUpdate has no callers outside its own test. Either wire it up or drop it from this PR.
🟢 Nits / minor

Two pre-existing type errors in handleAutoUpdate.test.ts (TS2322 at line 52, TS2540 at line 219) were detected by tsc --noEmit but fall outside the PR diff — they should be fixed separately.
…ck safety, shell injection, lock race, test coverage Five issues raised in PR #4629 review (2026-06-01): 1. Windows bat: add errorlevel checks after each move, rollback on second-move failure, timestamped log to qwen-update.log 2. Unix rollback: inner try/catch on recovery rename; compound error with manual mv instructions if both renames fail 3. Shell injection: assertSafeForShellEmbed() validates paths before embedding in /bin/sh wrappers and shell rc (platform-aware: allows backslash on Windows) 4. Lock-file race: bat writes .swap sentinel before rename; acquireLock refuses to reclaim stale-PID lock while sentinel exists 5. Test coverage: 4 new handleAutoUpdate standalone-path tests (done, deferred, error, npm-not-entered) + 3 shell-safety rejection tests

There was a problem hiding this comment.
[Suggestion] t(\Rollback failed: ${result.detail}`)creates a dynamic i18n key containing filesystem paths (e.g.,"/home/user/.local/lib/qwen-code.old does not exist"). This will never match the registered locale key 'Rollback failed: no previous version found (.old directory missing).', so the error message always renders in English regardless of locale. The registered key in en.js, zh.js, and zh-TW.js` is dead code.

(Also update the locale files to register 'Rollback failed:' as the key, and remove the dead full-sentence key.)

[Suggestion] smokeTest validates that --version output matches a semver regex but never compares it to the requested newVersion. A CDN misconfiguration (or, without signature enforcement, a targeted attack) could serve an older archive at the URL for a newer version. The checksum passes (attacker controls SHA256SUMS), the smoke test passes (valid semver), and the installation is silently downgraded to a version with known vulnerabilities.
Pass newVersion into smokeTest and assert the output matches:
const expected = newVersion.replace(/^v/, '');
if (version !== expected) {
throw new Error(
`Smoke test failed: expected version ${expected}, got ${version}`,

There was a problem hiding this comment.
[Suggestion] When the npm prefix is not writable and auto-update is enabled, this code silently sets isStandalone: true with a fallback standaloneDir. This triggers performStandaloneUpdate in handleAutoUpdate.ts, which downloads to ~/.local/lib/qwen-code/, creates ~/.local/bin/qwen, and modifies .zshrc/.bashrc to prepend ~/.local/bin to PATH — all without user confirmation.
Users who installed via sudo npm install -g never opted into the standalone distribution channel. The silent shell rc modification is particularly concerning for enterprise environments with strict dotfile management.
Consider requiring an interactive confirmation before the first npm→standalone migration, or at minimum gating behind an explicit opt-in setting.

[Suggestion] findStandaloneDir() (upward manifest walk) and the npm-to-standalone migration fallback (lines 207-243: accessSync writability check, HOME='/' guard, fallback standaloneDir construction) have zero test coverage despite being the entry point for the entire standalone update feature.
The existing test file adds accessSync: vi.fn() to the mock setup but introduces no new test cases exercising these ~50 new lines. At least 5 distinct branches are uncovered: manifest found, manifest missing/malformed, npm prefix writable, npm prefix not writable with valid HOME, npm prefix not writable with HOME='/'.

Thanks for the PR, @yiliang114!
Template looks good — all required sections are in place. ✓
On direction: this lines up well with what the ecosystem is doing. Claude Code has been actively working on auto-updater reliability, native installer support (winget, native binary distribution), and CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE for non-npm installations. Standalone self-update is a natural fit for where Qwen Code is heading.
Before diving into the code, the question I always ask: is this the simplest approach? In this case, the answer is yes — downloading + verifying + atomically swapping the installation directory is the straightforward path. The Windows deferred-update bat script adds complexity, but that's a platform necessity, not an engineering choice.
Moving on to code review. 🔍

方向上，这与行业趋势吻合。Claude Code 一直在推进 auto-updater 可靠性、原生安装器支持（winget、native binary distribution）以及 CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE 等非 npm 安装路径。Standalone 自更新是 Qwen Code 自然的下一步。
看代码之前我也在想：这是否是最简洁的方式？答案是肯定的——下载、校验、原子替换安装目录就是最直接的路径。Windows 延迟更新 bat 脚本确实增加了复杂度，但这是平台限制，不是工程选择。

[Critical] Windows sentinel file has no staleness check — a single crash permanently blocks all future updates.
If the .bat script crashes or the machine loses power between writing .qwen-update.lock.swap (line 445: echo swap-in-progress > "${sentinelFile}") and the :cleanup phase that deletes it, the sentinel persists forever. acquireLock refuses to reclaim a stale-PID lock when the sentinel exists, so all future update attempts silently fail with "Another update is already in progress". There is no timeout-based recovery, no max-age check on the sentinel, and no /doctor subcommand or error message that tells the user how to fix it.

[Suggestion] ensureBinWrapper never refreshes an existing wrapper — stale wrappers silently break qwen after path changes.
The if (!fs.existsSync(wrapperPath)) guard skips writing if the file exists, regardless of content. If standaloneDir changes (relocation, migration), the wrapper continues pointing to the old directory, and qwen silently fails. Replace the existence check with a content check:

[Suggestion] Windows zip extraction via Expand-Archive has no explicit path traversal filter, unlike the tar path.
The tar extraction (line 225-229) has two layers of defense (preservePaths: false + filter: (p) => !p.startsWith('/') && !p.includes('..')), but the Windows path delegates entirely to PowerShell's Expand-Archive. While modern .NET (4.7.2+) includes built-in zip-slip protection, this creates an asymmetric defense-in-depth gap. Consider adding a post-extraction walk to validate all entries stay within destDir:
| if (target.startsWith('win')) { | |
| await new Promise<void>((resolve, reject) => { | |
| const ps = spawn( | |
| 'powershell.exe', | |
| [ | |
| '-NoProfile', | |

| `Expand-Archive -Path '${escapePS(archivePath)}' -DestinationPath '${escapePS(destDir)}' -Force`, | |
| ], | |
| { stdio: 'ignore' }, | |
| ); | |
| ps.on('close', (code) => | |
| code === 0 | |
| ? resolve() | |
| : reject(new Error(`Expand-Archive exited with code ${code}`)), | |
| ); | |
| ps.on('error', reject); | |
| }); | |
| // Verify no extracted entry escaped destDir (defense-in-depth for older .NET) | |

The fixes from earlier rounds that address real scenarios are in place (bat error handling, archive timeout, stderr capture, discriminated rollback result). For the latest round — sentinel staleness, shell meta inconsistency, symlink guard — I've removed these mechanisms entirely in c401f52. CI passes on all platforms. Why remove instead of fix forward: These mechanisms were incrementally added across review rounds, creating a cycle — each fix introduced new code, which got flagged in the next round. The sentinel itself was added to solve the lock race, then the sentinel's own lack of staleness recovery became the next finding. Continuing would only increase complexity without addressing real-world risks. Threat model: these scenarios don't occur in practice
What's retained:
Remaining suggestions: Version comparison in smoke test, wrapper refresh, zip-slip, npm→standalone migration UX — reasonable improvement directions, not blocking bugs. Will track separately as follow-ups. 中文说明前面几轮有价值的修复已经落地（bat error handling、archive timeout、stderr 捕获、discriminated rollback result），这些是真实场景会遇到的。 最近几轮的 sentinel 超时、shell meta 不一致、symlink guard 等问题，重新评估后选择直接移除（c401f52a6），CI 全平台通过。 原因：这些机制是逐轮 review 叠加进来的，形成循环 — 每次修复引入新代码，下一轮又扫出新问题。比如 sentinel 本身就是为 lock race 加的，结果自己又带来了"crash 后永久阻塞"。继续修只会越来越复杂，而这些场景实际上不会发生。 剩余建议（版本比对、wrapper 刷新、zip-slip、迁移 UX）作为 follow-up 单独跟进。 |

[Suggestion] binDir is embedded inside double quotes in the shell rc file (export PATH="${binDir}:$PATH") without escaping characters special inside POSIX double quotes (", `, $, \). Same issue in the Unix wrapper script at line 473 (exec "${standaloneDir}/bin/qwen"). Paths containing these characters would break the script or allow injection. Consider escaping or rejecting paths with shell-special characters.

This is the same concern as assertSafeForShellEmbed which was intentionally removed in c401f52 — see the earlier thread. The default path is ~/.local/lib/qwen-code (constructed from os.homedir()), which cannot contain shell metacharacters. The unsafeCmdChars check is retained for the bat script context where paths are interpolated into a detached script.

[Suggestion] ensureBinWrapper and ensurePathInShellRc failures use debugLogger.debug() — invisible in production. During npm→standalone migration, if these fail, the update reports success (debugLogger.info('Standalone update complete.')) but qwen is not on PATH. The user sees "Update successful!" and then command not found: qwen on their next invocation. Consider upgrading to debugLogger.warn() or surfacing the failure via the update event.

By design — these are best-effort convenience operations (wrapper creation and PATH update). The update itself already succeeded at this point. Upgraded the signature-skip log to warn in 316ead7, but keeping wrapper failures at debug to avoid alarming users when the primary update completed fine.

[Suggestion] Windows bat script spawned with {detached: true, stdio: 'ignore'} — there's no mechanism for the Node process to learn the bat script's outcome. The user sees "Update downloaded. It will be applied after you exit this session" but never gets confirmation the swap actually completed. If the bat script fails silently, the user's next session still runs the old version with no indication the update was never applied. Consider writing a sentinel file from the bat script that the next CLI invocation checks.

The sentinel mechanism was intentionally removed in c401f52 — see the earlier thread. The bat script already writes success/failure to qwen-update.log, which serves as the diagnostic surface. Adding another marker file re-introduces the staleness/orphan problem that motivated the removal.

[Suggestion] Double I/O: downloadToFile writes 50–150 MB to disk via pipeline(Readable.fromWeb(body), sizeGuard, dest), then verifyChecksum immediately re-reads the entire file with fs.createReadStream(filePath) to compute SHA-256. The hash could be computed during download by inserting a createHash('sha256') Transform into the pipeline, eliminating the redundant disk read.

Fixed in 316ead7 — downloadToFile now computes SHA256 during the download stream via a tee Transform, returning the hex hash. verifyChecksum accepts the pre-computed hash instead of re-reading the file. Single-pass, zero extra I/O.

There was a problem hiding this comment.
[Suggestion] npmPrefixDir = path.dirname(path.dirname(realPath)) resolves to the scoped package namespace dir (e.g. @qwen-code), not the npm prefix (/usr/local). For this scoped package, two levels of dirname don't reach lib/node_modules — they land at @qwen-code. The writability check works by coincidence since ownership is usually shared, but the variable name npmPrefixDir and the comment about lib/node_modules are both inaccurate. Consider renaming to npmPackageParentDir and clarifying this is a writability heuristic.

[Suggestion] Windows bat script wait loop: when the PID is no longer found by tasklist | find, the && block is skipped and execution falls through to :proceed with zero buffer delay. The move command then races NTFS file-handle release that occurs asynchronously after process termination. On systems with antivirus scanners or indexers, this window can be extended. Consider adding timeout /t 2 >nul between the wait loop and :proceed for a safe buffer.

The bat script has been stable across multiple E2E validations. The wait loop with tasklist | find + :proceed label is the standard cmd.exe pattern for PID polling. No behavioral change needed.

[Suggestion] rollbackDoctorAction (~55 lines, 6+ branches) has zero behavioral test coverage. The diff only adds tab-completion assertions. None of these branches are tested: non-standalone install, Windows platform, interactive/non-interactive success/failure, rollback failure with RollbackResult.

[Suggestion] downloadWithFallback discards per-mirror failure reasons. tryFetch catches errors at debug level and returns null; the thrown error says "Failed to download ... from both OSS and GitHub mirrors" with no WHY (timeout? DNS? 403? SSL?). When both CDNs fail, users have zero diagnostic info without finding the debug log file.
Suggested fix: have tryFetch return { response, error } or capture the last error, then include both reasons in the thrown message:

`Failed to download ${filename}: OSS (${ossError ?? 'unknown'}), GitHub (${ghError ?? 'unknown'})`,
);— qwen3.7-max via Qwen Code /review

[Suggestion] In the catch block: when rename #1 (standaloneDir to .failed) succeeds but rename #2 (.old to standaloneDir) fails, the recovery code renames .failed back to standaloneDir (restoring the install). But the returned error detail still says Manual recovery: mv "${oldDir}" "${standaloneDir}" — misleading because the install is already restored and following this instruction would overwrite the working install with .old.
After successful recovery, update the detail message to indicate the install was restored and remove the manual mv instruction.

Fixed in 316ead7 — after successful auto-recovery (failedDir → standaloneDir), the detail now says "Current installation was restored automatically" instead of the stale mv instruction.

[Suggestion] For bash, ensurePathInShellRc prefers .bashrc over .bash_profile. On macOS, Terminal.app opens login shells by default, which read .bash_profile but NOT .bashrc. If a user has both files, the PATH export goes to the unread .bashrc and ~/.local/bin/qwen is effectively not on PATH.

There was a problem hiding this comment.
[Suggestion] On Windows, atomicReplace returns 'deferred' — the bat script performs the actual rename asynchronously. The code here checks if (fs.existsSync(oldDir)) immediately, but .old doesn't exist yet (the bat hasn't run). The bat script also doesn't write rollback metadata. So Windows deferred updates permanently lack .qwen-rollback-info.json, and /doctor rollback cannot show the preserved version.
Consider writing the metadata to the .new directory before spawning the bat (it will end up alongside the promoted install after the swap), or add metadata writing to the bat script after the successful swap.

E2E Test Report — Post-Review-Fix ValidationRan after applying multi-model review fixes (commit 316ead7). All scenarios verified with real OSS download on macOS arm64. Results
What was verified in the update flow:
Environment
Unit Test Results
Review fixes applied in this commitSecurity: per-mirror error details preserved, SHA256SUMS.sig download deduped, Windows ZIP path traversal guard, tar symlink target validation, shell metacharacter validation for rc/wrapper files, atomicReplace validate-before-mutate Correctness: spawnAndCapture string error code fix, lock leak on mkdtempSync failure, rollback concurrent lock guard, rollback auto-recovery message fix, i18n dynamic key fix, detectTarget unsupported arch rejection Performance: single-pass SHA256 during download (eliminates re-reading 50-150 MB archive) Raw tmux E2E output |
Standalone installs (via install-qwen-standalone.sh) previously fell through to npm global detection, causing auto-update to run `npm install -g` which doesn't update the standalone binary. Now the CLI detects standalone installs by looking for manifest.json in ancestor directories, then performs a self-update: download archive from OSS/GitHub, verify SHA256, extract, and atomically replace the installation directory. Includes: input validation (semver + target allowlist), lockfile for concurrency, Windows deferred replacement via helper script, and tar path traversal protection. Closes #4627
- Smoke test: spawn new binary with --version after extraction, before replacing the installation. Rejects broken/wrong-arch packages. - Rollback: keep .old directory after updates. Export rollbackStandaloneUpdate() for future /doctor rollback integration. - Signature: Ed25519 verification of SHA256SUMS via node:crypto. Embeds public key; CI signs with scripts/sign-release.sh. Graceful degradation when .sig is not yet published (transition period). Set QWEN_REQUIRE_SIGNATURE=1 to enforce strict mode.
- Fix TS4111: use bracket notation for process.env index signature - Fix CodeQL: validate paths for cmd.exe metacharacters before bat script - Fix Windows lock race: keep lock alive during deferred swap, release in bat script after move completes
- handleAutoUpdate: handleUpdateFailed/handleUpdateSuccess now read the message from the event payload instead of hardcoding text. Windows deferred users now see the correct "applied after exit" message. - Add standalone-update.test.ts with 4 tests covering rollback scenarios.
1. SHA256SUMS: handle GNU coreutils binary-mode `*` prefix in filename 2. acquireLock: treat NaN (empty/corrupt lock file) as stale, not held 3. tryFetch: consume response body on non-OK status to release sockets 4. Windows bat: add 30s timeout to PID wait loop preventing infinite hang 5. Finally block: clean orphaned .new directory on Windows error path
Tests previously asserted hardcoded handler text. After making handlers read messages from event payload, the assertions need to reflect the emitted payload values instead.
…itable When a global npm install requires sudo (prefix not writable), the auto-update now falls back to the standalone path instead of spawning a doomed `npm install -g` that always EACCES. - installationInfo.ts: detect writable prefix with fs.accessSync; return isStandalone=true with fallback dir when not writable - standalone-update.ts: support first-time migration (no existing manifest), detect platform target, create bin wrapper, refuse to overwrite unmanaged directories Closes #4643
…headers - Fix Windows deferred update: move pendingDir cleanup to catch block so it only runs on error, not on successful deferred path - Add ensurePathInShellRc: auto-append ~/.local/bin to shell rc on npm→standalone migration so the wrapper is actually discoverable - Wire rollbackStandaloneUpdate into /doctor rollback subcommand - Add license headers to all 4 new source files - Fix spawnAndCapture double-settle with settled flag - Add tests for ensureBinWrapper and ensurePathInShellRc - Clarify signature verification comments (test key, not production)
The mustTranslateKeys test requires zh-CN and zh-TW translations for all built-in command descriptions. Add translations for the new rollback subcommand and its user-facing messages.
The ensureBinWrapper Unix-wrapper test asserts on POSIX file mode bits (mode & 0o111) which Windows NTFS does not implement. Skip Unix-specific tests when running on Windows runners.
- Add assertPathWithin() and resolve install paths before spawning the smoke-test process. Closes the CodeQL "shell command built from environment values" finding by guaranteeing nodeBin/cliBin stay inside the freshly extracted install directory. - Add performStandaloneUpdate test coverage for the four pre-flight failure cases (bad version, missing manifest, unknown target, concurrent lock) so the core update path is no longer untested.
…ck safety, shell injection, lock race, test coverage Five issues raised in PR #4629 review (2026-06-01): 1. Windows bat: add errorlevel checks after each move, rollback on second-move failure, timestamped log to qwen-update.log 2. Unix rollback: inner try/catch on recovery rename; compound error with manual mv instructions if both renames fail 3. Shell injection: assertSafeForShellEmbed() validates paths before embedding in /bin/sh wrappers and shell rc (platform-aware: allows backslash on Windows) 4. Lock-file race: bat writes .swap sentinel before rename; acquireLock refuses to reclaim stale-PID lock while sentinel exists 5. Test coverage: 4 new handleAutoUpdate standalone-path tests (done, deferred, error, npm-not-entered) + 3 shell-safety rejection tests
Replace fixed-name .qwen-code-update-staging with mkdtempSync random suffix — an attacker who can write to parentDir can no longer pre-create a symlink to hijack recursive deletion. Also adds lstat guard before cleanup rmSync (defense-in-depth) and fixes a potential tempDir leak if mkdtempSync for extractDir fails.
…coverage, cleanup logging - Add MAX_DOWNLOAD_BYTES (512 MB) streaming size guard in downloadToFile to prevent resource exhaustion from oversized responses - Extend UNSAFE_SHELL_META_UNIX to also reject semicolon and single-quote - Add debugLogger.warn when extractDir cleanup is skipped (unexpected type) - Add Windows backslash acceptance test for assertSafeForShellEmbed
…l, shell-rc validation Defense-in-depth improvements from independent code review: - Explicitly set preservePaths:false on tar extract to prevent symlink path traversal - Check err.signal in spawnAndCapture for cross-platform timeout detection - Validate binDir in ensurePathInShellRc independently of calling context
…ollback result type 1. Separate ARCHIVE_TIMEOUT_MS (5 min) from FETCH_TIMEOUT_MS (30s) so large archive downloads on slow networks don't time out prematurely 2. Capture stderr from smoke-test execFile and include it in the error message so users see the actual crash reason (missing lib, etc.) 3. Change rollbackStandaloneUpdate return from boolean to discriminated result type (ok/reason/detail) so doctorCommand shows accurate messages for each failure mode instead of a generic "not found"
The 'rejects standaloneDir with embedded double-quote' test called fs.mkdirSync on a path containing `"`, which ENOENTs on Windows since NTFS forbids `"` in path components. The validator assertSafeForShellEmbed runs synchronously before any FS access in ensureBinWrapper, so the pre-mkdir was vestigial — removing it makes the test pass on Windows without weakening the assertion.
Remove theoretical security mechanisms that solve near-impossible attack scenarios but introduce real complexity and new bug surface: - sentinel mechanism (solves a <2s race window requiring 3 independent low-probability events to align) - assertSafeForShellEmbed + UNSAFE_SHELL_META regexes (default paths are ~/.local/lib/qwen-code, never contain metacharacters) - assertPathWithin (execFile doesn't invoke shell; CodeQL false positive) - lstatSync symlink guard (mkdtempSync random naming already prevents predictable symlink pre-creation) Retains unsafeCmdChars in atomicReplace (bat script interpolation is a real context), bat error handling, archive timeout, and stderr capture.
Security: - Preserve per-mirror error details in downloadWithFallback diagnostics - Deduplicate SHA256SUMS.sig download via downloadWithFallback - Upgrade signature-skip log from info to warn with enforcement hint - Add post-extraction path traversal validation for Windows ZIP - Add symlink target validation in tar extraction filter - Add shell metacharacter validation (assertSafeForShellEmbed) for binDir in ensurePathInShellRc and standaloneDir in ensureBinWrapper - Validate cmd.exe metacharacters BEFORE filesystem mutation in atomicReplace Windows path Correctness: - Fix spawnAndCapture treating string error codes as exit 0 - Release lock when mkdtempSync for extractDir fails - Add concurrent lock protection to rollbackStandaloneUpdate - Fix misleading manual-recovery message after auto-recovery succeeds - Fix t() dynamic i18n key — split into translated prefix + raw detail - Reject unsupported architectures in detectTarget instead of silent fallback to linux-x64 Performance: - Compute SHA256 hash during download stream (single-pass), eliminating the second full read of the 50-150 MB archive Quality: - Fix macOS bash shell rc priority (.bash_profile over .bashrc) - Rename npmPrefixDir to npmPackageDir for accuracy - Extract magic number 3 to MAX_MANIFEST_SEARCH_DEPTH constant Tests: - Add rollback concurrent lock protection tests (live + dead PID) - Add fish shell ensurePathInShellRc test - Add shell metacharacter rejection test for ensurePathInShellRc

What this PR does
Adds self-update capability for standalone installations. When Qwen Code detects it was installed via the standalone installer (not npm/pnpm/yarn), it now downloads the new release archive from OSS/GitHub, verifies its SHA256 checksum, extracts it, and atomically replaces the installation directory — all without requiring sudo or any package manager.
Key implementation details:
manifest.jsonpresence under~/.local/lib/qwen-code/.new/.oldstaging with rollback on failure.batscript (applied after process exit)ensurePathInShellRc()prepends~/.local/binto the user's shell rc fileWhy it's needed
Standalone installs (
~/.local/lib/qwen-code/) were not recognized byinstallationInfo.ts. They fell through to the npm global fallback, causing auto-update to runnpm install -g— which either fails with EACCES (if npm prefix requires root) or installs to a different location without updating the standalone binary.Reviewer Test Plan

这个 PR 做了什么
为 standalone 安装添加自更新能力。当 Qwen Code 检测到自身通过 standalone 安装器安装（非 npm/pnpm/yarn）时，会从 OSS/GitHub 下载新版本 release 归档，验证 SHA256 校验和，解压并原子替换安装目录——无需 sudo 或任何包管理器。
关键实现：
manifest.json检测 standalone 安装.new/.old暂存目录原子替换，失败时回滚.bat脚本延迟更新（进程退出后执行）ensurePathInShellRc()在用户 shell rc 文件中 prepend~/.local/bin为什么需要
Standalone 安装（
~/.local/lib/qwen-code/）未被installationInfo.ts识别，会错误回退到 npm global——要么 EACCES 失败（npm prefix 需要 root），要么安装到不同位置而不更新 standalone 二进制。评审测试计划
