Architecture
A defensive interface organizes scenario evidence, explanations, and human acceptance without autonomous enforcement.
Data flow
Reviewed input -> typed boundary -> tool mechanism -> reviewable artifact -> human decision
Provenance
Record the repository commit, configuration, input identifiers, execution command, output location, and validation result. A screenshot alone is not a reproducible artifact.
Failure behavior
Missing configuration, unavailable dependencies, invalid input, and failed tests must remain visible. The tool must not replace a failure with invented success.
