   2   * Mocked Tests for Architect Agent
   3   *
   4   * Uses mock.module() to replace LLM-dependent modules, enabling coverage of:
   5   * - updateDocumentation (LLM path)
   6   * - createDesignProposal (LLM path)
   7   * - reviewImplementationPlan (LLM approved and needs_changes paths)
   8   * - identifyAffectedDocs env var detection (lines 1721-1727) via mocked fs/promises
   9   * - checkBranchHealth inner catch blocks (lines 1474-1478, 1520-1524)
  10   * - checkBranchHealth stale branch detection (lines 1503-1517)
  11   * - summarizeChanges diff path (lines 1758-1759)
  12   * - profilePerformance outer catch (lines 1643-1649)
  13   *
  14   * CRITICAL: mock.module() calls must appear BEFORE any import of architect.js.
  15   * The module under test is loaded via dynamic await import() after mocks are set up.
