- `role="status"`를 사용하여 비어있는 상태(empty-state)가 스크린 리더에서 올바르게 읽히도록 개선
- 숫자 데이터 가독성 향상을 위해 테이블 셀에 `font-variant-numeric: tabular-nums;` 적용
- 테이블 행(row)에 대한 hover 격리(isolation) 및 트랜지션 적용으로 시각적 피드백 제공
- 사용자의 OS 애니메이션 줄이기 설정(prefers-reduced-motion)을 지원하는 미디어 쿼리 추가
- 키보드 내비게이션 사용자를 위한 `main` 태그의 focus outline 처리 및 skip-link의 `focus-visible` 개선

 ## 2026-08-04 - Focus Visible For Scrollable Code Blocks
 **Learning:** Code blocks (`<pre>`) that contain wide text (like JSON or CSV exports) require horizontal scrolling, but by default they cannot receive keyboard focus, locking keyboard-only users out of viewing the full content.
 **Action:** Always add `tabindex="0"`, `role="region"`, `aria-label`, and a `:focus-visible` outline to scrollable `<pre>` or code containers to ensure full keyboard navigability and clear visual focus feedback.
+## 2026-08-05 - ARIA Live Regions and Tabular Nums for Diagnostics
+**Learning:** Empty states in dynamically generated reports using basic `<p>` tags are often skipped by screen readers. Furthermore, displaying financial or statistical data without aligned decimals can cause extreme eye strain and layout shifting for the users.
+**Action:** Used `<div class="empty-state" role="status">` for any dynamic empty message sections so that screen readers correctly announce the lack of data to users without vision. Used `font-variant-numeric: tabular-nums;` in all report table cells to naturally align metric statistics.

 - Added `render_essay_score_report_html`, which replay-verifies one governed `EssayScoreReport` and emits a deterministic, source-text-free, script-free standalone HTML audit artifact.
 - The artifact exposes exact report, assessment, rubric, task-revision, engine, request, result, observation, criterion, trigger, and evidence-reference identities through semantic landmarks, keyboard-accessible exact-value tables, and canonical JSON.
+- Empty states use explicit status semantics, numeric table cells use tabular numerals, skip links remain visible for any received focus, and motion-sensitive users receive a reduced-motion override without dimming non-hovered report rows.
 - A restrictive meta-delivered Content Security Policy and output encoding reduce content-injection impact. Review routing remains an audit signal only and does not establish scoring validity, fairness, reliability, interchangeability, accessibility conformance, security certification, or authorization for consequential deployment.

+## 2026-08-05 - Status Semantics and Numeric Alignment for Reports
+**Learning:** Explicit status semantics can make conditionally rendered empty states easier to discover with assistive technology, while tabular numerals improve visual comparison of metric columns. Focus-reveal behavior must not depend only on `:focus-visible`, and hover styling must not reduce the contrast of unrelated rows.
+**Action:** Use `role="status"` for genuine conditionally rendered status messages, apply `font-variant-numeric: tabular-nums` to numeric report tables, reveal skip links on `:focus`, retain a visible `:focus-visible` indicator, and avoid opacity-based dimming of non-hovered content.

 - Added `render_essay_score_report_html`, which replay-verifies one governed `EssayScoreReport` and emits a deterministic, source-text-free, script-free standalone HTML audit artifact.
 - The artifact exposes exact report, assessment, rubric, task-revision, engine, request, result, observation, criterion, trigger, and evidence-reference identities through semantic landmarks, keyboard-accessible exact-value tables, and canonical JSON.
+- Empty states use explicit status semantics, numeric table cells use tabular numerals, skip links remain visible for any received focus, and motion-sensitive users receive a reduced-motion override without dimming non-hovered report rows.
 - A restrictive meta-delivered Content Security Policy and output encoding reduce content-injection impact. Review routing remains an audit signal only and does not establish scoring validity, fairness, reliability, interchangeability, accessibility conformance, security certification, or authorization for consequential deployment.

 ## 2026-08-04 - Focus Visible For Scrollable Code Blocks
 **Learning:** Code blocks (`<pre>`) that contain wide text (like JSON or CSV exports) require horizontal scrolling, but by default they cannot receive keyboard focus, locking keyboard-only users out of viewing the full content.
 **Action:** Always add `tabindex="0"`, `role="region"`, `aria-label`, and a `:focus-visible` outline to scrollable `<pre>` or code containers to ensure full keyboard navigability and clear visual focus feedback.
-## 2026-08-05 - Status Semantics and Numeric Alignment for Reports
+## 2026-08-04 - Status Semantics and Numeric Alignment for Reports
 **Learning:** Explicit status semantics can make conditionally rendered empty states easier to discover with assistive technology, while tabular numerals improve visual comparison of metric columns. Focus-reveal behavior must not depend only on `:focus-visible`, and hover styling must not reduce the contrast of unrelated rows.
 **Action:** Use `role="status"` for genuine conditionally rendered status messages, apply `font-variant-numeric: tabular-nums` to numeric report tables, reveal skip links on `:focus`, retain a visible `:focus-visible` indicator, and avoid opacity-based dimming of non-hovered content.
