# The Xcode each macOS runner pool builds with, keyed by the runner's macOS
# major version (`sw_vers -productVersion`).
#
# scripts/select-ci-xcode.sh reads this file when a job does not pin an Xcode
# itself, so a job selects by the pool it actually landed on rather than by the
# lane it was routed through. Every version here must have the major named in
# .xcode-version; tests/test_ci_macos_xcode_selection.py enforces that.
#
# The macOS 15 pool carries Xcode 26.3 at most; the macOS 26 pool defaults to
# 26.6. macOS 27 hosts (the AWS M4 Pro workers after their in-place upgrade)
# carry Xcode 26.6 for CI next to Xcode 27, because every pin keeps the
# .xcode-version major. Bump a line only after the pool's image carries that
# Xcode.
