Fix main's red CI: macOS Composer on PHP 8.4 and the setup-php pin comment - #1102

Conversation
Since 2026-10-07 23:51Z every Composer compatibility run has failed
its macOS 2.10.3 / PHP 8.5 cell in "Setup PHP": setup-php 2.37.2
cannot install PHP 8.5 from Homebrew now that PHP 8.6 has shipped
("php: command not found", "Could not setup PHP 8.5"). This keeps
main red on every push.
Run that cell on PHP 8.4, which Composer 2.10.3 supports. Ubuntu and
Windows keep the 2.10.3 / PHP 8.5 cell, so 8.5 is still covered.

The upstream v2 tag moved off f3e473d1, so zizmor's ref-version-mismatch audit now fails every merge group that touches workflows. f3e473d1 is 2.37.2, the label composer-compatibility.yml already uses. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Problem
Every Composer compatibility run since 2026-10-07 23:51Z fails its macOS
composer 2.10.3 / php 8.5cell in "Setup PHP". The 10 most recent runs all failed there, on main and on PRs (e.g. main run 37712459222):On 10-07, Homebrew's PHP formulas were reshuffled when PHP 8.6 was published (shivammathur/homebrew-php). Since then, setup-php 2.37.2 (our pinned version, the latest stable) can't install PHP 8.5 on macOS. The other macOS cells (PHP 8.1 and 8.3) still pass.
Fix
Run the macOS 2.10.3 cell on PHP 8.4, which Composer 2.10.3 supports. Ubuntu and Windows keep the
2.10.3 / 8.5cell, so PHP 8.5 is still covered. The macOS row indocs/testing/composer-compatibility.mdis updated to match.Validation
The macOS legs no longer run on PRs (#1093), so I dispatched the workflow on this branch: run 37715262908 (result in a follow-up comment).
Also: zizmor
ref-version-mismatchonci.ymlThe org's Audit GHA Workflows check now fails any merge group that touches workflows (for example #1050, run 37749840803). It flags
ci.yml:1400,shivammathur/setup-php@f3e473d1 # v2: the upstreamv2tag has moved off that commit.f3e473d1is tag2.37.2(verified with the GitHub API), so the comment now says# 2.37.2, matchingcomposer-compatibility.yml. The pin itself is unchanged. #1058 has the same one-line fix, but it is a much larger PR.🤖 Generated with Claude Code

Overview
Fixes failing macOS Composer compatibility CI after Homebrew/setup-php stopped providing PHP 8.5 once PHP 8.6 landed (Setup PHP step:
php: command not found).The
native-macosmatrix cell for Composer 2.10.3 now runs on PHP 8.4 instead of 8.5, with an inline comment documenting the setup-php limitation. Ubuntu and Windows still use 2.10.3 / 8.5, so PHP 8.5 coverage is unchanged overall. The macOS row indocs/testing/composer-compatibility.mdis updated to 2.10.3 (8.4).Reviewed by Cursor Bugbot for commit b4cba52. Configure here.
