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).

      # The Windows job verifies the new portability work this PR delivers,
      # not the entire free suite. After v1.20.0.0 ships, full-suite Windows
      # parity is a P4 follow-up TODO that depends on porting many tests off
      # POSIX-bound surfaces (raw /tmp paths, /bin/bash hardcodes, bash
      # shebang spawns, mode-bit assertions, deleted v1.14 sidebar refs, etc).
      #
      # The curated subset enumeration in scripts/test-free-shards.ts is
      # retained for future expansion — `bun run test:windows --list` gives
      # contributors a starting point to grow Windows coverage incrementally.
      #
      # What we verify here is exactly the new code paths v1.20.0.0 ships:
      #  - bin/gstack-paths state-root resolution (test/gstack-paths.test.ts)
      #  - browse/src/claude-bin.ts Bun.which wrapper + override + arg-prefix
      #    resolution including the GSTACK_CLAUDE_BIN=wsl PATHEXT path
      #    (browse/test/claude-bin.test.ts)
      #  - scripts/test-free-shards.ts curation logic itself
      #    (test/test-free-shards.test.ts)
