I used Claude Fable 5.1 to generate the fix and reviewed it manually.

If multiple resources have a SHA mismatch, the error was not naming the resource, only stating Resource reports different checksum, one example I encountered:

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Checksum mismatch reports now identify the downloadable by its displayed name, making it clearer which item failed verification.
  • The report continues to show the expected and actual checksum values alongside the checksum label.

Checksum-mismatch reports in serial and parallel fetch paths now use downloadable.download_queue_message to label the reported checksum. The tests check the label in both modes and check the checksum output on stdout in serial mode.

Changes: Checksum mismatch reporting

Layer / File(s)	Summary
Use downloadable messages in checksum reports Library/Homebrew/download_queue.rb, Library/Homebrew/test/download_queue_spec.rb	Both fetch paths pass the downloadable message to the alignment helper. Tests check the Bottle testball label in stderr and, in serial mode, the downloaded-file checksum in stdout.

Priority: Low

Full details: Title check

Explanation

The title names the change: checksum mismatch errors in the download queue now name the download. This matches the raw summary, which says the labels now use the downloadable's message, and the PR objectives, which say the resource name is added to each error. The title is specific and concise.

Full details: Description check

Explanation

The description explains the problem and the intended result. When several resources fail SHA-256 verification, the error does not name the resource. It gives an example output and shows the corrected output with the resource name. This matches the changes to the download queue and its spec file.
