Signal Tags

@betterdata/signal-tags-schema provides JSON Schema contracts for cryptographically anchored product identity and provenance workflows.

​
What Signal Tags Are

Signal Tags define a structured identity + traceability model for products, lots, and custody events. The package ships schemas, fixtures, and typed schema-aligned TypeScript definitions.
