+## Decisions
+
+- **Domain-specific constants vs Global**: The constants were found specifically within `torch/src/services/memory/`. Therefore, I created `torch/src/services/memory/constants/` rather than a global `src/constants.js`.
+- **Time constants**: Created `time.js` for `SECOND_MS`, `MINUTE_MS`, `HOUR_MS`, `DAY_MS`, `WEEK_MS`, `MONTH_MS`.
+- **Text constants**: Created `text.js` for `MAX_SUMMARY_LENGTH`.
+- **Scoring constants**: Created `scoring.js` for `DEFAULT_IMPORTANCE_SCORE` and `LOW_IMPORTANCE_THRESHOLD`.
+- Replaced literals in `index.js`, `pruner.js`, `retriever.js`, `ingestor.js`, `summarizer.js`, `cache.js`, `scheduler.js`.
