I have already done a preliminary review for you, and I hope to help you do a better job.
Summary:

This pull request aims to improve the efficiency of fetching files from artifacts by not pulling all files but just the needed file. To achieve this goal, the PR adds a new function called fetch_file_from_oci_artifact(). The function retrieves the file blob digest and downloads the file from the OCI artifact.

Potential problems:

1. The fetch_file_from_oci_artifact() function is not tested, which can lead to bugs in the future.
2. The build_and_push_images() function in build-package-images.sh.tmpl still has the old code that pulls all files from OCI repositories. It should be removed to avoid confusion.

Suggestions:

1. Add unit tests to the fetch_file_from_oci_artifact() function to ensure its reliability.
2. Remove the old code that pulls all files from OCI repositories in build_and_push_images().

Overall, the changes in this pull request look good, but it would be better to address the above-mentioned issues before merging it.

I have already done a preliminary review for you, and I hope to help you do a better job.
Summary:

• The pull request aims to improve the efficiency of fetching files from artifacts.
• The changes include a new function fetch_file_from_oci_artifact, which is used to get the specific file blob digest and download the file from the OCI repository.
• The oras pull command is replaced with fetch_file_from_oci_artifact in the archive() and compose_artifact() functions.

Potential problems:

• The pull request does not include any tests to ensure that the new function works as expected.
• The build_and_push_images() function in build-package-images.sh.tmpl has a new assertion that len $ociFiles should be 0, which seems unrelated to the changes made in this pull request. This assertion should be moved to a separate pull request.

Fixing suggestions:

• Add tests to validate the new fetch_file_from_oci_artifact function.
• Move the assertion in build_and_push_images() to a separate pull request.
• Consider refactoring the function names to make them more descriptive and consistent with the project's naming conventions.
