+
+### Fixed
+- **Wear Leveling / Percentage Used showing raw write count instead of percentage** — ATA wear-related attributes (`Media_Wearout_Indicator`, `SSD_Life_Left`, `Percent_Lifetime_Remain`, etc.) were reading the `RAW_VALUE` column from smartctl, which contains a vendor-specific counter (e.g., 1569 total writes). Now reads the normalized `VALUE` column (0–100), which is the actual percentage remaining. Fixes drives incorrectly showing values like "1,568%" instead of "100%". ([#7](https://github.com/DAB-LABS/smart-sniffer/issues/7))
+
+### Changed
+- **README: scan interval documentation** — agent configuration section now documents Go duration syntax (`30s`, `5m`, `1h`, `24h`) and notes that each poll wakes spun-down drives
+- **README: roadmap additions** — per-drive scan intervals, standby-aware polling, and YAML-based attribute definitions added to roadmap
