🎨 Palette: Update empty state ARIA semantics to use div

[seonghobae]

💡 What: Changed <p> to <div> for empty-state containers in python/fast_mlsirm/scoring/essay/validation_report_html.py.
🎯 Why: Screen readers may skip <p> tags with ARIA live region roles in dynamic or conditionally rendered areas. Using <div> ensures assistive technologies correctly announce missing data.
📸 Before/After: Code-only change in HTML output.
♿ Accessibility: Ensures empty state status messages are robustly announced by assistive technology.

📝 Walkthrough

Walkthrough

The empty identifier state in the essay validation HTML report now uses a <div> with status semantics. The related test expectation and accessibility guidance were updated.

Changes

Accessible empty-state rendering

Layer / File(s)	Summary
Empty-state markup and validation python/fast_mlsirm/scoring/essay/validation_report_html.py, tests/test_scoring_essay_validation_report_html.py, .Jules/palette.md	The empty identifier state now uses a <div> with preserved role="status", aria-atomic="true", and escaped message content. The test and guidance describe the updated markup.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 7e42d1cd601b4bb78a5049cb402a0700da8f2042.

Closing unmerged after exact-current review. Protected main already exposes the bounded accessibility contract in docs/doctoring/essay_validation_empty_state_accessibility.md: role="status" supplies the advisory live-region semantics, explicit aria-atomic="true" preserves whole-message atomicity, and the documentation deliberately does not claim a cross-screen-reader or initial-render announcement guarantee.

The proposed <p> → <div> swap has no standards-backed accessibility requirement on its own. The current W3C ARIA-in-HTML Recommendation explicitly permits Any role on a p element (p has implicit paragraph semantics), and WAI-ARIA defines the live behavior on the explicit status role itself (aria-live="polite", aria-atomic="true"). Therefore the added .Jules/palette.md claims that <p> may be ignored and that <div role="status"> ensures/triggers announcement overstate the available evidence. Main's existing <p role="status" aria-atomic="true"> is conforming and more accurately documented.

Current product CI, Security Scan, and SAST are green on this head, but the exact-head OpenCode review is also CHANGES_REQUESTED because central coverage evidence failed on a trusted-uv archive HTTP bootstrap; that central control-plane failure is independent of this product conclusion and is not a reason to churn the product branch.

No useful unique product behavior remains to preserve here, so this PR is closed as not justified rather than merged or rewritten. Standards consulted: W3C ARIA in HTML Recommendation (2026-04-15), WAI-ARIA 1.2 status, and ARIA22.
