Correct the parse() API description.
NpmMetadataAdapter.parse() parses an npm-view package object. A package-lock root object has no package name, so this method returns None. State that parse_lockfile() handles package-lock v2 and v3 files.

Use npm’s --json option for metadata retrieval.
npm view treats json as a field selector. The adapter can therefore receive empty output and return None.
Change the command, test expectation, and changelog entry to use --json.

Validate the decoded lockfile shape before reading it.
A valid JSON value such as [] reaches Line 419 and raises AttributeError because lists have no get(). A dictionary with "packages": [] later raises on items(). Return [] unless both the root value and packages are dictionaries.

Extract the package name from the final node_modules segment.
When an npm lockfile entry omits info["name"], path.replace("node_modules/", "") maps node_modules/a/node_modules/b to a/b, so the adapter returns a instead of b. Use path.rsplit("node_modules/", 1)[-1] before splitting scoped and unscoped names.

Homebrew brew info --json=v2 formulae casks response format official
💡 Result:
The Homebrew brew info --json=v2 command provides a JSON representation of Homebrew formulae and casks [1][2]. Unlike the deprecated v1 format, which only supports formulae, v2 is designed to return data for both formulae and casks [2][3]. Key characteristics of the v2 response format include: Structure: The top-level element of the JSON output is an array (or a dictionary containing "formulae" and "casks" keys, depending on the specific implementation context) [1][3]. Schema Stability: While fields may be added to the schema as needed without incrementing the version number, any significant breaking changes will result in a new schema version [1][4]. Usage: You can execute this via command line as brew info --json=v2 [formula|cask]. If run without arguments (e.g., brew info --json=v2 --eval-all), it can return information for all available packages [3][5]. Documentation: Homebrew does not maintain a static, external document detailing every field in the v2 JSON schema [1][4]. Instead, the schema is defined by the internal Ruby code (specifically formula.rb and the info command implementation) that generates it [4][3]. For those integrating with Homebrew data, the official Homebrew JSON API documentation provides examples of the data structure for individual formulae and casks [6]. Users are advised that the exact output format may vary between Homebrew versions, and it is recommended to use standard JSON parsing tools like jq to handle the data [1][7]. If you need a stable, long-term API for integration, the public JSON API at formulae.brew.sh is the official, documented alternative [4][6].

🌐 Web query:
site:docs.brew.sh/Querying-Brew "brew info --json=v2" "formulae"
💡 Result:
The command brew info --json=v2 is used in the Homebrew package manager to output information about available packages in a machine-readable JSON format [1]. While the default schema version, v1, only provides information about formulae, the v2 schema explicitly includes both formulae and casks in its output [1]. This JSON output is designed to be parsed by external tools or scripts, and while Homebrew may add new fields to the schema as needed, significant breaking changes are reserved for major schema version increments [1].
Citations:
Handle the Homebrew v2 wrapper response.
brew info --json=v2 can return a top-level object with formulae and casks. BrewMetadataAdapter.fetch() accepts only lists, so it returns None for this response. BrewMetadataAdapter.parse() treats the wrapper as the package and produces empty metadata. Update the adapter to extract the requested formula or cask before parsing, and update the Brew fixtures to cover the wrapper shape.
