name: Windows Free Tests

# Curated subset of the free test suite that runs on windows-latest.
#
# Codex's v1.18.0.0 review flagged that the existing evals.yml workflow uses
# a Linux container, so a windows-latest matrix entry there isn't a drop-in.
# This workflow is non-container, runs the curated Windows-safe subset, plus
# targeted resolver tests that exercise the Bun.which-based claude binary
# resolution + the GSTACK_CLAUDE_BIN override path on Windows.
#
# What this DOES NOT do (out of scope for v1.18.0.0):
#   - Run the full free suite on Windows. The 24 tests that hardcode /bin/sh,
#     spawn('sh',...), or raw /tmp/ paths are excluded by scripts/test-free-shards.ts
#     --windows-only. They need POSIX-bound surfaces to be ported off shell
#     primitives before they can run on Windows. Tracked as a follow-up TODO.
#   - Run Playwright/browser-backed tests. Browse server bring-up on Windows is
#     a separate concern (PR #1238 windows-pty-bun-pty-fix is in flight).
