Use YYLO artifact Records

Treat Ledger as the source of truth for artifact identity and metadata. Use yy ledger in a YYLO controller or yylo-ledger standalone.

A Ledger Artifact Record is durable evidence, not an npm/Python release artifact and not an implicit request to publish or deploy.

• report: a generated human- or machine-readable result;
• receipt: evidence binding an operation and its inputs/outcome.

Choose payload mode deliberately:
