🎨 Palette: [HTML 테이블 행 헤더 접근성 개선]

[seonghobae]

💡 What: calibration_report_html.py와 validation_report_html.py 내부 테이블 렌더링 시 첫 번째 식별자 열에 row_header_column=0 파라미터를 추가했습니다.
🎯 Why: 기존에는 데이터 행의 첫 번째 식별자 열(Task ID, Engine ID, Metric 등)이 <td>로 렌더링되어 스크린 리더 사용자가 표 안의 데이터를 읽을 때 어떤 행의 데이터인지 인지하기 어려웠습니다.
📸 Before/After: 시각적 디자인은 유지하면서 <th>와 scope="row"가 적용되도록 하였습니다. (접근성 트리 상의 구조 개선)
♿ Accessibility: scope="row"를 통해 행 헤더 시맨틱이 부여되므로, 스크린 리더 사용자가 데이터 표를 논리적으로 탐색하고 이해하기 편해집니다.

📝 Walkthrough

Walkthrough

The report renderers now mark the first column of each table as a row header. The HTML test also checks focus-visible styling for scrollable tables and preformatted content.

Changes

HTML report accessibility

Layer / File(s)	Summary
Row headers and focus styling python/fast_mlsirm/scoring/essay/calibration_report_html.py, python/fast_mlsirm/scoring/essay/validation_report_html.py, tests/test_scoring_essay_report_html.py	Calibration and validation tables pass row_header_column=0. The report test checks :focus-visible styling for .table-scroll and pre elements.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to de473

This is a localized accessibility improvement to HTML table semantics with no supplied evidence of correctness, runtime, deployment, or availability risk; it is merge-ready after normal checks, and no actionable merge-blocking risk remains.

📝 Info: Threshold table row header is not an identifier column

The thresholds table marks its 'Lower category' column as the row header via row_header_column=0, unlike the other tables whose first column is a unique identifier (Task/Engine/Respondent ID). The evidence table in python/fast_mlsirm/scoring/essay/report_html.py:297-309 deliberately omits row_header_column because its first column repeats. Worth confirming lower-category values are unique enough to serve as row headers.

113-113: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add a direct regression check for row headers.

Line 113 checks only the focus-visible CSS. It does not detect removal of row_header_column=0 from either report renderer. Add an assertion for <th scope="row"> in the rendered calibration and validation tables, or confirm that another test covers both _render_html implementations.

Closing this as a duplicate/superseded accessibility lane. Live PR #997 already owns these exact essay-report files and the same row_header_column=0 production changes for facets-calibration and validation tables, with a dedicated regression suite that asserts <th scope="row"> semantics for both renderers. #997 also carries the related pointer-focus/print accessibility work and governed documentation. This PR additionally contains an unrelated uv.lock regeneration, so landing it separately would create a competing writer and mix packaging churn into the accessibility slice. No code from this PR needs to land independently.

Understood. Acknowledging that this work is now superseded by #997 and stopping work on this task.
