Round 3 of windows-free-tests fixes. Round 2 (LF gitattributes + server-node.mjs
build) cleared shard 1 entirely (skill-collision-sentinel and tab-isolation
green). Shard 2 surfaced two more issues:
1. browse/test/claude-bin.test.ts:50 — the "PATH-resolvable override" test
creates a fake binary 'fake-claude-cli' (no extension) and expects
Bun.which to find it. On Windows, Bun.which probes PATHEXT extensions
(.cmd, .exe, .bat) — a bare-name file is not discoverable. Production
behavior is correct; the test was Mac/Linux-shaped.
Fix: branch on process.platform. On Windows, write 'fake-claude-cli.cmd'
with a Windows batch payload instead of a POSIX shebang script.
2. test/gstack-question-log.test.ts (and 18 sibling tests) — spawn a bash
shebang script via spawnSync(BIN, args). Git Bash on Windows can run
`bash /path/to/script` but spawnSync invokes CreateProcess directly,
which doesn't parse #!/usr/bin/env bash. All these tests are
Windows-fragile and can't run as-is.
Fix: extend WINDOWS_FRAGILE_PATTERNS with `path.join(.., 'bin', ..)`
detector. Curates 19 additional tests (benchmark-cli, brain-sync,
builder-profile, explain-level-config, gbrain-*, gstack-question-*,
hook-scripts, learnings, plan-tune, review-log, secret-sink-harness,
taste-engine, telemetry, timeline, uninstall).
Curated Windows subset: 95 → 76 tests (~59% of free suite). Still
meaningful Windows coverage. The 52 excluded tests are tracked as a
follow-up TODO for full Windows parity (shebang-bin spawns + POSIX file
modes + raw /tmp/ etc).
