🧾 PR Checklist

• Target branch is dev

📌 Note: PRs must be raised against dev. Do not commit directly to main.

📁 File Hygiene & Output Handling

• No unintended files (e.g., logs, cache, temp files, pycache, output folders) are committed

📝 Comments & Communication

• Proper inline comments are added to explain important or non-obvious changes

• PR title and description clearly state what the PR does and why

• Related issues (if any) are properly referenced (Fixes #, Related to #, etc.)

• Problem summary

  • run-mlperf-inference-submission-checker is shared by inference and automotive.
  • Version selection needed to move away from top-level versions and into version variations to support both tracks cleanly.

• What changed

  • Meta refactor (single file):
    • script/run-mlperf-inference-submission-checker/meta.yaml
    • Removed top-level version mapping usage (default_version + populated versions block), keeping versions: {}.
    • Converted version handling to variation-based mapping.
    • Applied reviewer feedback to make metadata concise using version.#.
    • Kept explicit overrides where behavior differs:
      • version.master (default) → master
      • version.r6.0 → master

• Representative snippet

  variations:
    version.master:
      default: true
      group: version
      adr:
        submission-checker-src:
          version: master
  
    version.#:
      group: version
      adr:
        submission-checker-src:
          version: '#'
  
    version.r6.0:
      group: version
      adr:
        submission-checker-src:
          version: master
  
  versions: {}

🛡️ Safety & Security

• No secrets or credentials are committed
• Paths, shell commands, and environment handling are safe and portable

@copilot can't we use version.# here to make the meta concise?

[Copilot]

Done in cc3bde4. I switched to a concise version.# variation and kept explicit overrides only where behavior differs (version.master default and version.r6.0 mapping to master).
