+**Agent Report Summary**
+- **Branch**: maintenance/cleanup-and-todo-refactor
+- **Commit**: 9a97d6132d8f293d9507e857f22ebb65bc7de03f
+- **Diff Summary**: Moved 14 standalone scripts from root `scripts/` to `backend/scripts/` to consolidate python tooling, updating internal relative path logic inside them. Standardized all TODO complexity attributes across `backend/` and `tests/` to use (`Small`, `Medium`, `Large`, `Epic`) instead of the deprecated (`Low`, `Medium`, `High`) values.
+
+**Scan Results**
+- Unused files: []
+- Generated artifacts removed: []
+- Ambiguous files: []
+- Misplaced files moved: [scripts/analyze_churn_plot.py, scripts/debug_import.py, scripts/dev.py, scripts/extract_todos_structured.py, scripts/generate_sample_reports.py, scripts/pruning_plan.py, scripts/test_available_models.py, scripts/test_model_availability.py, scripts/update_active_context.py, scripts/update_all_notebooks.py, scripts/update_models.py, scripts/update_notebook_models_gemini.py, scripts/update_notebooks_gemma3.py, scripts/verify_env.py]
+
+**TODOs**
+- Valid TODOs: 30
+- Stale TODOs: []
+- Ambiguous TODOs: []
+- TODO complexity changes: Changed 22 TODOs from 'Low' to 'Small', and 5 TODOs from 'High' to 'Large'.
+
+**Convention Enforcement**
+- Enforcements applied: Moved backend tooling into `backend/scripts/` per AGENTS memory guidelines; updated `TODO` syntax per new complexity standards.
+- Matched patterns: Python tools logic; TODO complexity schema.
+- Convention adherence score: 100
+
+**Verification**
+- Commands run: `python backend/scripts/extract_todos_structured.py`, `git diff --stat`, `uv run ruff check --fix backend/src/ backend/scripts/`, `uv run pytest tests/`
+- Verification status: pass
+- Failure conditions encountered: []
+
+**Risk Assessment**
+- Risk summary: Low risk. The scripts moved are utility and maintenance scripts not actively invoked by the core runtime. The TODO changes are purely structural string updates inside comments.
+- Files requiring human review: []
+
+**Next Steps**
+- Recommended actions: []
+- Suggested reviewers: []
+- Labels: [cleanup, automated, needs-review]
+
+**Machine Metadata**
