Summary

Adds 8 integration tests in est/cli/team-root-resolution.test.ts verifying SQUAD_TEAM_ROOT env-var resolution across all scenarios:

Tests added

getSquadStartDir() env-var handling (3 tests)

• Returns SQUAD_TEAM_ROOT when env var is set
• Falls back to process.cwd() when unset
• Falls back to process.cwd() when empty string

resolveSquad() integration (3 tests)

• Finds .squad/ when SQUAD_TEAM_ROOT points to a valid project
• Finds .squad/ even when cwd is elsewhere (Copilot CLI bang-command scenario)
• Returns null when SQUAD_TEAM_ROOT is unset and cwd has no .squad/

Invalid SQUAD_TEAM_ROOT path (2 tests)

• Returns null for a non-existent path
• Returns null for a dir without .squad/

Context

PR #763 added \getSquadStartDir()\ + 2 tests in
ap-subprocess.test.ts, but there were no tests verifying SQUAD_TEAM_ROOT works across all resolution scenarios, and no tests simulating the Copilot CLI bang-command subprocess scenario where cwd differs from the interactive shell.

Test-only PR — no product code changes.

Closes #836

Pull request overview

Adds an integration-style Vitest suite to validate SQUAD_TEAM_ROOT start-directory behavior (including the Copilot CLI bang-command “cwd differs” scenario) by exercising getSquadStartDir()-equivalent logic and resolveSquad() results.

Changes:

• Adds coverage for SQUAD_TEAM_ROOT set / unset / empty-string behavior.
• Adds resolveSquad() scenarios for valid team roots, mismatched cwd, and invalid/non-existent roots.

[Copilot]

This test assumes fakePath does not exist, but join(tmpdir(), 'squad-nonexistent-' + Date.now()) can collide with an existing directory/file (e.g., leftover from a prior run), making the test flaky. Consider generating a guaranteed-nonexistent path (e.g., create a temp dir with mkdtempSync and immediately remove it, or append a random suffix and expect(existsSync(fakePath)).toBe(false) before calling resolveSquad).

[tamirdresher]

✅ LGTM — Solid integration tests for SQUAD_TEAM_ROOT resolution. Proper temp dir setup/teardown.
