"""Tests for .opencode/scripts/pipeline-status.py — mandatory project map.

Verifies the deterministic check_project_map: docs/project-map/README.md is
required for every pipeline-driven PR (ADR-028). Loaded under a unique module
name (``pipeline_status_project_map``) so it does not collide with other test
modules that load the same script as ``pipeline_status``.
