- Missing packages/files: No explicit missing package/file errors shown; issue is due to version mismatches (Ruby and Bundler) rather than missing dependencies.
- Version mismatch info:
  - Ruby version: image reports 3.4.9 vs Gemfile specifying 3.4.8
  - Bundler/lockfile: lockfile generated with Bundler 2.4.6, while Bundler 4.0.8 is running; installer attempts Bundler 2.4.6 to rebuild using that version.
- Key Bundler/Ruby messages:
  - Bundler 4.0.8 is running, but lockfile was generated with 2.4.6; installing Bundler 2.4.6 and restarting using that version.
  - Your Ruby version is 3.4.9, but your Gemfile specified 3.4.8
- Recommendations (actionable):
  - Align Ruby: use Gemfile-specified 3.4.8 in the base image or update Gemfile to 3.4.9.
  - Align Bundler: regenerate the lockfile with the Bundler version you intend to use (either install Bundler 2.4.6 and run bundle install, or upgrade to Bundler 4.x consistently).
  - Verify the base image tag exists or switch to a supported Ruby Alpine tag that matches your Gemfile.

  - Failing subcommand: thor docs:download --all

- Missing packages or files mentioned:
  - The error indicates a missing Thor subcommand ("docs"), i.e., the docs:download task is not available. This implies the Thor command "docs" is not provided by the installed gems or not defined in the Thorfile.

- Version mismatch information:
  - Base image: ruby:3.4.8-alpine3.23
  - Bundler installed: 2.4.6
  - Thor installed: 1.4.0
  - No explicit version mismatch reported; the failure is due to the missing Thor "docs" command rather than a version incompatibility.

  - The command failed during thor docs:download --all (docs command not found by Thor)

- Missing packages or files mentioned
  - No missing OS packages or files were reported. The error relates to a missing Thor command (docs) rather than a missing package. Specifically: Could not find command "docs".

- Version mismatch info
  - No explicit version mismatch reported. Base image used: ruby:3.4.8-alpine3.23. Bundler 2.4.6 was installed. Post-install messages include typical deprecation notices (e.g., Ruby Sass), but none indicate a version mismatch causing the failure.
