name: Windows Smoke

# The required Windows check under minimal support (docs/support-tiers.md):
# with a default Git for Windows install, ./setup installs and the core skills
# start. One windows-latest job, under 5 minutes:
#   1. ./setup --host claude into an isolated HOME under Git Bash, with
#      gstack's own browser (Playwright Chromium).
#   2. The core skills start: gstack-skill-start for /ship, /review,
#      /qa-only, /investigate and /browse answers SKILL_START_PROTO: 1.
#   3. /browse on gstack's own browser: the installed browse runs a piped
#      chain flow against a local page from an unrelated directory.
#   4. The fastest Windows-safe free tests for those paths (list below).
# The full curated Windows suite is windows-free-tests.yml: nightly on main
# and on dispatch, never a PR gate.
#
# No bun install cache: a cold install took 16-17 s on windows-latest, a
# restore of the ~450 MB cache 33-42 s (GSTA-203 PR 1 A/B, 3 runs per arm).
