+## 5) Validation Results
+
+### Baseline validated state (before cleanup)
+
+- `python -m pytest -q` -> 822 passed, 0 failed, 40 skipped
+- `python scripts/validate_stft_reference.py` -> 3 passed
+
+### Final verification (after cleanup)
+
+- `python -m pytest -q` -> 822 passed, 0 failed, 40 skipped, 996 warnings
+- `python scripts/validate_stft_reference.py` -> 3 passed, 13 warnings
+
+## 6) Semantic Summary
+
+- `density.py`: Python 3.9 annotation compatibility fix (`from __future__ import annotations`).
+- `compile_metrics.py`: log density adjusted to `log10(1 + sum(A))`; explicit `power_sum` debug basis preserves `Power_raw`.
+- `metrics_dictionary.json`: repaired `quantity_type` values and `derived_from` references.
+- Fixtures: deterministic benchmark audio fixtures and clean external-validation sample fixtures were added.
+
+## 7) Readiness Statement
+
+This folder is cleanup-complete, validated after cleanup, and ready to be used as the source for applying changes to a clean Git clone.
