"""Tests for .opencode/tools/project-status.ts — the project_status custom tool.

Mirrors ``tests/test_spec_status_tool.py``: exercises the tool's
``execute()`` function via ``tests/_ts_loader.mjs`` (a node CommonJS
sandbox that strips TS-only syntax, stubs ``@opencode-ai/plugin``, and
replaces ``import.meta.dir`` with the real ``.opencode/tools`` directory).

The loader is parameterized via the ``TS_FILE`` env var. These tests set
``TS_FILE=.opencode/tools/project-status.ts``. ``buildExecArgs`` was
extended in ``_ts_loader.mjs`` to support the multi-arg boolean tool
(``check`` + ``fast``): the raw value is split on ``|`` and each part is
mapped to a boolean via ``/^true$/i``.

Modes used:
- ``load`` — sanity-check that the tool loads and has ``check`` + ``fast`` args.
- ``exec_stub`` — call execute with a stubbed spawnSync to verify:
  (a) ``--check`` / ``--fast`` flags added to argv correctly,
  (b) stdout is trimmed on success,
  (c) non-zero exit without ``check`` returns an actionable error message,
  (d) non-zero exit WITH ``check`` returns the trimmed stdout (strict mode),
  (e) ``cwd`` is propagated from ``context.worktree`` (ADR-023).
- ``exec_real`` — call execute against the real project-status.py
  (integration test, non-blocking so always exit 0 in this repo).
