📝 WalkthroughWalkthroughThe changes add a shared release-asset verifier and harden npm, PyPI, and release-verification workflows. Workflows now require protected ChangesRelease governance and verification
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The updated workflows restrict publication to protected releases and validate package contents, but the verifier still accepts mutable release assets and does not fully bind the manifest to the release's source commit. An authorized actor who can alter release assets could publish a self-consistent but unreviewed npm or PyPI package set, so merge should wait for these controls to be fixed or explicitly accepted.

GitHub immutable releases REST API release immutable field published release can be edited assets tags
💡 Result:
When GitHub immutable releases are enabled, they provide a security mechanism that prevents tampering with release assets and tags after a release is published [1][2]. Key restrictions for immutable releases include: - Assets: Once a release is published as immutable, all attached assets are locked and cannot be added, modified, or deleted [1][2]. - Tags: The associated Git tag is locked to a specific commit. It cannot be moved, deleted, or repurposed while the immutable release exists [1][2]. - Editing: After an immutable release is published, editing is restricted [3][4]. Users can typically only modify non-sensitive metadata, such as the release title and release notes [3][4]. Because of these restrictions, GitHub recommends a best-practice workflow of creating a release as a draft, attaching all necessary assets, and verifying details before final publication [1][3][4]. Once published, the immutable nature of the release ensures that the software remains secure and trustworthy, with the added benefit of automatically generated release attestations for verifying artifact integrity [1][2]. The REST API exposes an immutable boolean field in the release object, which indicates whether a specific release is currently immutable [5][6]. While users with push access can use the REST API to update releases, the immutability enforcement logic remains active, meaning API requests to modify assets or protected tags for an immutable release will be rejected [7][8][1].

Require an immutable release.
Without .immutable == true, the publisher can download a self-consistent but replaced asset set from a mutable release. Add the immutability check before downloading assets.

authoritative npm package.json bin field behavior and Python wheel archive required METADATA WHEEL RECORD files
💡 Result:
The npm package.json bin field and Python wheel archive metadata files serve specific, distinct purposes in their respective ecosystems [1][2][3]. npm package.json bin field The bin field in package.json is used to define executable files that should be installed into the system PATH [1][4]. Behavior and Configuration: - Map or String: You can define it as a map (object) where the key is the command name and the value is the local file path, or as a string if there is a single executable that should use the package name as its command [1][5]. - Installation: When installed globally, npm creates symbolic links or Windows-compatible command files (e.g.,.cmd,.ps1) in the system's global binary directory [1][5]. When installed as a dependency, the files are linked into the node_modules/.bin/ directory [6]. - Execution: Scripts referenced in the bin field should ideally start with a shebang line like #!/usr/bin/env node to ensure they are executed with the correct interpreter [1][4]. - Mutual Exclusion: Specifying both the bin field and the directories.bin configuration is considered an error; use one or the other [1][4]. Python Wheel Archive Metadata A Python wheel (.whl) is a ZIP-format archive that contains a.dist-info directory [7][3]. This directory must contain at minimum three specific files: METADATA, WHEEL, and RECORD [2][8][9]. Required Metadata Files: - METADATA: Contains package metadata, similar to the PKG-INFO file found in source distributions (sdist), following the Metadata format specification (version 1.1 or greater) [2][9]. - WHEEL: Contains metadata specific to the wheel build itself, including the wheel specification version, the generator (the tool that created the wheel), and compatibility tags (e.g., Python version, ABI, platform) [2][8][7]. - RECORD: A mandatory list of (almost) every file contained within the wheel archive [2][9]. - Function: It acts as an integrity check [3]. Each entry typically includes the file path, a secure hash (must be sha256 or better), and the file size [2][8]. - Exceptions: The RECORD file itself is not hashed and therefore not listed in its own content [2][8]. Signature files (like RECORD.jws or RECORD.p7s), which are deprecated but may still appear in older wheels, are also excluded from the RECORD file [2][8][10]. - Verification: During installation, tools must verify the hashes of all files in the archive against the entries in RECORD; if any hash does not match, the installation will fail [2][9][11]. Top Results: [1][2][9][7]

site:packaging.python.org/specifications/binary-distribution-format RECORD required wheel archive WHEEL METADATA exact wording
💡 Result:
The RECORD file in a Python wheel archive is defined as a list of almost all files contained within the wheel, accompanied by their secure hashes [1]. The specification requires that every file in the archive, with the exception of the RECORD file itself, must be included in this list with its hash [1]. Regarding the format, the specification mandates the following: 1. Hash Algorithm: The hash algorithm used must be sha256 or better; md5 and sha1 are explicitly not permitted [1]. 2. Inclusion Requirements: Apart from RECORD, as well as the deprecated files RECORD.jws and RECORD.p7s, installation will fail if any file in the archive is not both mentioned and correctly hashed in the RECORD file [1]. 3. Exclusion: The files INSTALLER and REQUESTED must not be included in the archive, and consequently, they do not appear in the RECORD file [1]. While the technical documentation highlights these requirements, it notes that the RECORD file cannot contain a hash of itself [1]. Installers verify all hashes in the RECORD file against the actual file contents during the extraction process [1].

Create structurally valid package fixtures.
The npm fixture declares bin/coderouter.js, but the archive contains only package/bin-placeholder. The verifier checks only package.json, so it does not test the launcher file. Each wheel contains only METADATA; valid wheels also require WHEEL and RECORD. Add the declared executable with executable mode, complete wheel metadata, and archive-content assertions. Also list all five wheels in the mocked release assets.
