The "Known edge case" section covers 32-bit Windows, but psutil dropped 32-bit Linux (i686) wheels on the same boundary — and 32-bit Linux is a platform this package explicitly serves.

Evidence — wheel platform tags on PyPI:

psutil linux i686 wheel win32 wheel
6.1.1 yes yes
7.0.0 yes yes
7.2.2 no no

browserstack/local_binary.py:17,31-34 computes is_64bits = sys.maxsize > 2**32 and downloads BrowserStackLocal-linux-ia32 for 32-bit interpreters, so 32-bit Linux is a first-class target here. Windows, by contrast, has no bitness branch at all (local_binary.py:36 → a single BrowserStackLocal.exe). With the cap removed, a fresh install on a 32-bit Linux interpreter resolves psutil 7.2.2 and must compile it from sdist (gcc + Python headers) where 6.1.1/7.0.0 supplied a wheel — a minimal CI image without a toolchain fails the install outright.

Worth adding the flip side to the description as well: 7.2.2 gains musllinux wheels (x86_64 + aarch64) that 6.1.1 lacked entirely, so Alpine users (local_binary.py:26 → BrowserStackLocal-alpine) go from an sdist build to a wheel. Net wheel coverage improves for a supported platform.

Fix — either extend the documented edge case to win32 + linux i686 and accept it knowingly, or scope the cap to 32-bit so wheel coverage is preserved everywhere:

install_requires=[
    'psutil>=5.6.6',
    'psutil<7; platform_machine in "i686 i386 x86"',
]

On "environment markers cannot reliably detect interpreter bitness" — markers do expose platform_machine, which pip evaluates as i686 on 32-bit Linux and x86 for 32-bit CPython on Windows (a WOW64 process reports PROCESSOR_ARCHITECTURE=x86). I haven't tested that resolution myself, and platform_machine reflects the OS/WOW64 view rather than sys.maxsize, so worth a pip install --dry-run --platform manylinux2014_i686 check before relying on it.

Question for author: was 32-bit Linux considered alongside win32, or did the wheel audit look only at the Windows set (the LOC-7228 customer is on Windows)?

Good catch — answering your direct question first: the wheel audit only diffed the win32 set against 6.1.1/7.0.0 (the LOC-7228 customer was on Windows); i686 was not checked. You're right that it lost wheels on the same boundary, and unlike Windows, 32-bit Linux is a platform local_binary.py explicitly branches for (is_64bits → BrowserStackLocal-linux-ia32).

Re-verified your table against PyPI JSON:

psutil linux i686 wheels win32 wheels musllinux wheels
6.1.1 3 3 0
7.0.0 1 2 0
7.2.2 0 0 2

Going with extending the documented edge case rather than the scoped marker, for the reason you already half-flagged: platform_machine reflects the OS/WOW64 view, so a 32-bit CPython on a 64-bit kernel reports x86_64 and the marker wouldn't fire — while pip's wheel selection still follows interpreter bitness. That's arguably the more common 32-bit scenario today (i386 Docker images without linux32 personality), so the marker gives partial coverage in exchange for permanent resolver complexity on a shrinking platform. The failure mode it would guard is loud (compiler error at install time), not a silent runtime break.

Also folded your flip side into the description: 7.2.2 adds musllinux wheels that 6.1.1 lacked, so Alpine (BrowserStackLocal-alpine, also explicitly served) goes from sdist-build to wheel — net coverage improves for a supported platform.

PR description updated to cover win32 + linux i686 + the Alpine improvement.
