During May 2026, contributed to the pnpm/pnpm repository by developing a regression test that enforces minimumReleaseAge filtering within the pnpm outdated command. This work focused on ensuring that immature package versions are not suggested as upgrades when policy-driven maturity requirements are in place. Leveraging TypeScript, JavaScript, and Node.js, the test was anchored to the policyViolation-based maturity flow and integrated with the resolved getManifest logic. The approach enhanced upgrade accuracy, reduced false positives, and strengthened continuous integration coverage for dependency resolution. Documentation was provided to clarify the test’s role as a regression gate, supporting long-term durability of this behavior.
