Thanks for adding beginner-facing messages to these advanced OOP checks. I validated the implementation itself: all 11 assertions now have non-empty messages, the reference-solution test passes, the full suite on this branch passes, and the passing curriculum verifies successfully.

I cannot approve this PR in its current state for the following reasons:

1. The PR targets main. Contributor feature and fix PRs must target dev; main is reserved for verified release promotion from dev.
2. The branch is currently 19 commits behind dev and does not report the project CI matrix.
3. All six edited files were converted from LF to CRLF. git diff --check reports trailing whitespace on every changed line. Please preserve LF line endings and make git diff --check pass.
4. The PR description does not follow the repository template or record all required validation.
5. The exact six-file scope for curriculum: add actionable assertion messages to advanced OOP checks (batch 2 of 2) #108 is also covered by fix(curriculum): add actionable advanced OOP assertion messages #142, which targets dev and currently has green CI. Please coordinate there to avoid merging duplicate implementations. Given that overlap, closing this PR as superseded by fix(curriculum): add actionable advanced OOP assertion messages #142 is likely the cleanest path.

Validation performed here:

• python -m pytest tests/integration/test_solution_verify.py -q — 1 passed
• python -m pytest -q — 190 passed on this older branch
• python -m pythonlings --root tests/fixtures/passing_curriculum verify — passed
• AST audit — all 11 assertions have non-empty messages
• git diff --check — failed because of the CRLF conversion

[abhiksark]

The assertion changes are functionally sound, but this cannot merge as submitted: it targets main instead of dev, is 19 commits behind dev, has no project CI matrix, and converts all six files to CRLF so git diff --check fails. It also duplicates #142 for #108. Please close as superseded, or retarget/update the branch, restore LF endings, complete the PR template, and coordinate the duplicate scope before requesting another review.
