Summary

• Default CLI output is compact, official TOON with content-first home view, aggregates, empty states, truncation, and contextual help.
• Explicit --json preserves the versioned Sophon-compatible review protocol; --full expands bounded TOON records.
• Packed lifecycle coverage validates TOON parsing, structured errors, stale approval, end state, and a 75% representative output-size reduction.

Validation

• npm run check
• npm run test:e2e
