Full details: Validation Evidence

Explanation

Required evidence is incomplete for this visible README change. The reviewed diff changes only README.md, README_EN.md, and README_ZH.md; each adds the second <br/>, and the candidate focused test passes 7/7 (node --test test/readme-showcase.test.mjs). The reviewed range also passes git diff --check. However, the PR body provides no Visual evidence section, screenshot, recording, reproducible rendering steps, or separate perceptual review. The focused test checks README integrity and asset freshness, not the rendered sponsor spacing. Public final-head CI is still pending: 10 checks are reported, with test (18), test (20), and webm-artifact in progress; the CodeRabbit status is also pending. No generated or packaged artifact changed, so regeneration is not indicated, but the PR does not state that freshness rationale. In addition, README.md and README_EN.md remove two leading spaces from the changed <td> line, which is not mentioned by the claim of no unrelated changes.

Resolution

Add the template evidence fields. Provide one relevant before/after rendered README screenshot or precise reproducible rendering steps, and report perceptual review separately from automated checks. State that generated-artifact freshness is not applicable because only README source files changed and no generated input changed. Link completed checks for the final head after the pending CI jobs finish. Remove or explain the indentation-only changes in README.md and README_EN.md if the patch is intended to contain only the extra line break.
