+- Idempotent stream startup by preferring saved checkpoint over flags
+- S3 upload retry with `--retry` flag for `baseline` and `rotate` commands
+- Standalone `bintrail upload` command for S3 uploads
+- At-rest encryption for mydumper dump files (`dump --encrypt`)

+- Include `archive_state` data in status restore coverage
+- Add missing Archives section to MCP status tool
+- Emit GTID tracking events to prevent gaps in accumulated GTID set
+- Place `--outputdir` last in mydumper args for Docker wrapper compatibility
+- Skip shell script wrappers when resolving mydumper on PATH
+- Remove `Truncate(time.Hour)` from rotate cutoff so hourly partitions drop correctly
+- Parse mydumper 0.16+ metadata format
+- Replace `UTC_TIMESTAMP()` with `CURRENT_TIMESTAMP` in `archive_state` DDL
+- Show S3 upload progress in rotate output
+- Create partitions from current hour forward
+- Suppress usage output on command errors
