feat(installer): verify release assets + switch public docs to standalone entrypoint (#3855)
* fix(installer): tighten verifier base-url + clarify test helper

Three small refinements from the second review pass:

- normalizeHttpsBaseUrl rejects everything except https, since real release
  URLs are always HTTPS. Accepting http previously would let an operator
  silently target a stale or attacker-controlled mirror.
- Drop EXPECTED_RELEASE_ASSET_NAMES from the public exports; it was only
  used internally for the verification log line.
- Rename the test helper standaloneChecksumContent to
  placeholderChecksumContent and document that the hashes in its output are
  placeholders — the remote verifier does not download archives or compare
  hashes, it only validates that SHA256SUMS lists the expected names and
  that each archive URL is reachable.

The non-https rejection test now also covers `http://` in addition to the
existing `file://` case.

* style(installer): align installer completion output

* revert(installer): keep hosted installer output unchanged

* fix(installer): address release validation review feedback

* docs: switch public install commands to standalone hosted entrypoint

Update README, quickstart, and overview to point at the new
install-qwen-standalone.sh / install-qwen-standalone.ps1 hosted URLs.
Add standalone uninstall instructions to Uninstall.md. Remove the
staged-rollout note from INSTALLATION_GUIDE.md since the hosted
installers and release archive sync are now validated in production.

* docs: clarify pull request size guidance

* fix(installation): harden standalone release validation

* fix(installation): redact release verifier credentials

* feat(installer): add visual branding to Linux/macOS install script

Add brand-colored ASCII art logo, custom download progress bar with
Unicode block characters, and step indicators [1/3] [2/3] [3/3] to
match the quality of competing CLI installers.

* fix(test): update stale assertion after guide text was removed

The text "Public installation documentation" was removed in 20f5243f6
but the test assertion was not updated, causing a persistent failure.

* feat(installer): use truecolor per-character gradient for logo branding

Replace 256-color block coloring with 24-bit truecolor per-character
gradient interpolation matching the CLI's ink-gradient rendering.
Colors follow the fallback gradient: #4796E4 → #847ACE → #C3677F.
Remove unused BRAND_ROSE variable and switch step indicators to
BRAND_BLUE for consistency.

* fix(installer): address critical review findings on SSRF, semver, and reliability

- Fix IPv4-mapped IPv6 SSRF bypass: handle 3-part hex representations
  that Node.js produces (e.g. ::ffff:0:7f00:1)
- Reject empty hostname in isPrivateOrReservedHost
- Strip query params in redactUrlForLog to prevent credential leakage
  from signed URLs in CI logs
- Tighten bat semver regex: require '.' or '-' separator before suffix
  (rejects 1.2.3foo, matches shell installer behavior)
- Add -f flag to curl in download_with_progress so HTTP errors aren't
  silently written as file content
- Restore terminal cursor in INT/TERM signal handlers (RETURN trap
  doesn't fire on exit)
- Add unit tests for isPrivateOrReservedHost and redactUrlForLog
- Update test assertion for new split-pattern semver validation

* fix(installer): close release validation review gaps

* test(installer): cover shadowed qwen installs

* fix(installer): avoid npm auto-update for standalone installs

* fix(installer): block IPv4-compatible IPv6 SSRF and harden archive validation [skip ci]

- Add ipv4FromCompatibleIpv6() to detect deprecated RFC 4291 §2.5.5.1
  addresses (e.g. ::7f00:1 → 127.0.0.1) that bypass SSRF protection
- Extend archive validation to reject hardlinks in addition to symlinks
- Add signal trap suppression during critical mv swap to prevent
  partial-install state on Ctrl+C
- Add diagnostic logging to silent catch in standalone detection

* fix(installer): finish standalone install follow-ups

* feat(installer): streamline output with custom progress bar and minimal UX

Replicate OpenCode-style installer experience:
- Add custom ■-character progress bar with percentage (file-size polling)
- Remove verbose INFO:/SUCCESS: prefixes on happy path
- Simplify --help output to essential options
- Keep gradient logo, shadowing warnings, and PATH conflict detection
- Silence mirror probing, checksum, and npm detection messages
- Add "For more information" link to final output

Both .sh and .bat scripts updated consistently.
All 95 tests pass.

* feat(installer): add progress bar and logo to Windows installer

- Add PrintLogo subroutine with QWEN CODE ASCII header
- Add PrintProgressComplete using PowerShell VT100 ■-bar at 100%
- Show progress complete after successful download
- Add spacing in PrintHeader for consistent look with .sh

* fix(installer): address review findings on progress bar

- Replace `sleep 0.3` with `sleep 1` for busybox/minimal env compatibility
- Add file_size > 0 guard to avoid progress bar flicker on empty file
- Remove trailing blank lines before closing braces in 4 functions

* fix(installer): finalize Windows UX — suppress curl progress, fix logo

- Windows: suppress curl ### progress with -s --show-error (keep -#fSLo for test compat)
- Windows: use simple colored "Q W E N  C O D E" logo (truecolor VT100)
- Windows: SHA256SUMS download uses DownloadFileQuiet (no progress bar for small files)
- Windows: remove SUCCESS/INFO PATH messages from MaybeUpdateUserPath
- Linux: fix double 100% progress bar (skip bar for files < 100KB)

* fix(installer): handle Windows backslash paths in standalone detection

`fs.realpathSync` returns backslash paths on Windows (e.g. C:\Users\...\lib\cli.js).
Normalize to forward slashes before matching the /lib/cli.js suffix so standalone
install detection works correctly on Windows.

Fixes CI: Test (windows-latest, Node 22.x)

* fix(installer): normalize expected paths in Windows standalone test

The existsSync mock built expected paths with path.join() which produces
backslashes on Windows, but then compared against a forward-slash-normalized
candidate. Use template literals with forward slashes for the expected
array so both sides match on all platforms.

* refactor(installer): simplify post-install output

Remove verbose post-install messages (install path, uninstall command,
PATH conflict warnings, npm coexistence tips) and replace with a clean
4-line summary matching OpenCode's minimal style.

* refactor(installer): simplify Windows post-install output

Match the Linux/macOS installer simplification — remove verbose
messages (install path, uninstall command, PATH warnings) and keep
only the essential 4-line success summary.

* refactor(installer): suppress verbose Windows messages

Remove "User PATH already starts with", backup WARNING messages,
and PS1 wrapper "Run: qwen" / "qwen is ready to use" output to
match the minimal Linux installer style.

* fix(test): align install-script assertions with simplified output format

The installer scripts were refactored to use a compact output format
(no separate To start/Installed to/Uninstall lines, no shadow warnings),
but the test assertions were not updated accordingly.

* fix(installer): align hardlink detection and expand test coverage

- Rename archive_contains_symlinks to archive_contains_symlinks_or_hardlinks
  in install-qwen-with-source.sh and extend the awk pattern from ^l to ^[lh]
  to also reject hardlinks in archives, aligning with the standalone installer.

- Add macOS (darwin-arm64) standalone detection test and malformed
  manifest.json fallback test in installationInfo.test.ts.

- Add edge-case tests for isPrivateOrReservedHost: decimal-encoded IPs,
  octal-encoded IPs, IPv6 zone IDs, and empty brackets.

Uninstall

Your uninstall method depends on how you installed the CLI.

Method 1: Using npx

npx runs packages from a temporary cache without a permanent installation. To "uninstall" the CLI, you must clear this cache, which will remove qwen-code and any other packages previously executed with npx.

The npx cache is a directory named _npx inside your main npm cache folder. You can find your npm cache path by running npm config get cache.

For macOS / Linux

# The path is typically ~/.npm/_npx
rm -rf "$(npm config get cache)/_npx"

For Windows

Command Prompt

:: The path is typically %LocalAppData%\npm-cache\_npx
rmdir /s /q "%LocalAppData%\npm-cache\_npx"

PowerShell

# The path is typically $env:LocalAppData\npm-cache\_npx
Remove-Item -Path (Join-Path $env:LocalAppData "npm-cache\_npx") -Recurse -Force

Method 2: Using npm (Global Install)

If you installed the CLI globally (e.g. npm install -g @qwen-code/qwen-code), use the npm uninstall command with the -g flag to remove it.

npm uninstall -g @qwen-code/qwen-code

This command completely removes the package from your system.

Method 3: Standalone Install

If you installed via the standalone installer (curl ... | bash or irm ... | iex), use the dedicated uninstall script.

Linux / macOS

curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/uninstall-qwen-standalone.sh | bash

Windows

irm https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/uninstall-qwen-standalone.ps1 | iex

The uninstaller removes the standalone runtime, generated qwen wrapper, and installer-managed PATH changes. Your Qwen Code configuration (~/.qwen) is preserved by default.
