dsl-lite-preset-dev

Develop, modify, and improve DSL Lite data ingestion presets — YAML-based declarative ETL pipelines that transform raw security logs through Bronze/Silver/Gold layers into OCSF-normalized tables. Use when working with preset.yaml files, adding gold tables, mapping events to OCSF classes, adding lookup joins, creating new data sources, or modifying any file under pipelines/. Also use when the user mentions presets, data ingestion, OCSF mapping, gold tables, silver transforms, bronze layer, or preset.yaml.
