Start with tsdb/series_file.go at ReadSeriesKeyMeasurement, parseSeriesKey, and ParseSeriesKeyInto, then follow the call from tsdb/store.go DeleteShard and services/retention/service.go. Use the supplied retention-deletion crash as the starting case; done means shard deletion handles the reported series-key input without panicking, with regression coverage if the existing test structure identifies a suitable location.
