Adds
--check-licensesas an opt-in flag that detects copyleft (LC001) and unknown (LC002) licenses across a project's dependency tree, surfaced inline with the CVE scan in the same pass.LC001 flags copyleft licenses (GPL-2.0/3.0, AGPL-3.0, LGPL-2.x/3.0, EUPL, OSL, CDDL, CPL, EPL). LC002 flags dependencies with no declared license. npm gets the full tree via lockfile metadata; pnpm/Yarn/Bun scan direct dependencies only via packument fetch (transitive license data is not available without install). Findings are informational - they appear in the output but do not affect exit code or
--fail-on.Surfaces in terminal (compact and verbose), JSON (
licenseFindings), SARIF, single-folder HTML report, and multi-folder HTML report. The GitHub Action gains acheck-licensesinput (default"false") following the same pattern ascheck-overridesandcheck-maintenance.Closes #1058
