 ## [Unreleased]
 
+### Added
+
+- **Progress in `gob list`**: Running jobs with historical stats now show estimated progress percentage in their status (e.g., `running (73%)`). Requires at least one previous successful run.
+
+### Changed
+
+- **Stats merged into job responses**: Job statistics (run count, success rate, durations) are now included directly in job responses instead of being a separate type. This affects `--json` output from `list`, event payloads, and the `stats` command response.
