- CLI entry point with yargs parsing for speckl-compile <file> --output-dir --bom-format
- TypeScript parser with AST types for all SpeckDL primitives
- Generator for PROV-O JSON-LD provenance graphs
- Generator for CycloneDX v1.6 BOMs
- Generator for SPDX 3.0.1 BOMs
- E2E test verifying RetryHandler.speck parsing and all output formats

All tests pass.
