Summary

Describe the bug, fix, or feature clearly and briefly.

What Changed

• List the main code changes.
• List any API or behavior changes.
• List any follow-up work that is intentionally out of scope.

Tests

Every working PR must include at least one new simple, fast, targeted unit test when the change affects behavior, a bug fix, or a regression path.

• I added a new simple/fast unit test for this change, or documented why that is not applicable.
• I ran the new targeted test locally before opening this PR.
• I ran any other directly relevant local tests.

Paste the exact test commands and results here:

Review Requirements

AI-assisted code is welcome.

Every changed file must still be properly reviewed by a human before the PR is opened as ready for review.

We will not accept PRs that are effectively unreviewed AI output. Non-human-reviewed changes often introduce obscure structure, mismatched APIs, project-inconsistent code patterns, or unnecessary monkeypatching instead of a correct fix or clean feature expansion.

• I personally reviewed every file in this diff.
• I checked that the code matches existing project structure, APIs, and conventions.
• I avoided unnecessary monkeypatching and used the project's normal extension points where possible.
