CRAP (Change Risk Anti-Patterns) combines cyclomatic complexity with test coverage: cc^2 * (1 - cov)^3 + cc. It is computed at output time from the existing complexity and coverage data, so no analysis types change. - JSON: metrics.crap is a number with coverage data and null without it, so consumers can parse the key unconditionally. - Terminal and LLM markdown output show it next to coverage. - [crap].coverage_source selects direct (default) or transitive coverage.

V3 schemas reject the new field. The terminal coverage line and the LLM markdown section now show a score when one is present.
