feat: add rsigma fields subcommand for field catalog#65
Merged
Conversation
List all fields referenced by Sigma rules, correlations, and filters. Extracts field names from detection items, correlation group-by/condition fields, alias mappings, filter detections, and rule metadata. Optionally applies pipelines to show post-mapping field names. Flags: -r/--rules (required), -p/--pipeline (repeatable), --no-filters, --json. Table output sends data to stdout and stats to stderr. Pipeline field mapping summary included when pipelines are applied. 16 integration tests with insta inline snapshots covering detection, correlation, value_count condition fields, alias mappings, filters, --no-filters exclusion, pipeline transforms, JSON output, directory loading, keyword-only rules, and error cases.
