The NodeSecure project introduces its hidden capability called mama (ManifestManager), designed to manage and load npm manifests efficiently. This utility package provides essential functionalities for handling package.json files across the Scanner monorepo backend. Key features include integrity verification through hash extraction, module type detection inspired by node-modules-inspector, recursive entry file extraction using Node.js exports field, and parsing of the author field into a structured Contact interface.

The package also supports parsing package specifications and detecting local lockfiles. These capabilities are crucial for ensuring consistency between package manifests and registry uploads, helping identify potential security discrepancies known as manifest confusion. By offering utilities like integrity checking and module type analysis, mama contributes to safer and more reliable npm package scanning.
