_⚠️ Potential issue_ | _🟡 Minor_

**Verify fallback import path exists before inserting into `sys.path`.**

This prevents accidental path pollution and aligns with path‑existence requirements.

 except ImportError:
     import sys
-    sys.path.insert(0, os.path.join(os.path.dirname(__file__), '..', 'packages', 'core', 'ai_content_pipeline'))

```
In `@tests/test_project_structure.py` around lines 31 - 34, The fallback import
block unconditionally inserts a constructed path into sys.path which may not
exist; before modifying sys.path in the except ImportError handler, verify the
fallback directory exists (os.path.join(os.path.dirname(__file__), '..',
'packages', 'core', 'ai_content_pipeline')) and only insert it if
os.path.isdir(...) is True, otherwise raise a clear ImportError mentioning the
missing fallback so ai_content_pipeline.project_structure is not referenced when
the path is absent.
