🎨 Palette: [접근성] 빈 상태의 버튼 비활성화 시 네이티브 disabled 속성 적용

[seonghobae]

Buyer-visible outcome

When a project has no tasks, CSV export and Gantt actions are natively disabled, removed from the interaction order, and explained through persistent visible help plus a polite live region. The explanation tells the customer exactly how to recover: add a new top-level task or import a project. When the first task is added, both actions return to their normal enabled state.

Accessibility and UX contract

• initial HTML is already disabled before hydration, closing the pre-hydration activation window;
• native disabled is the interaction-order authority for unavailable task-dependent actions;
• aria-disabled remains synchronized as explicit state metadata;
• unavailable actions retain aria-describedby to the persistent visible recovery explanation;
• an always-present polite status region announces availability transitions to assistive technology;
• the active state removes the unavailable-description association while preserving normal action behavior;
• browser regressions cover keyboard reachability, recovery after adding a task, initial markup, live-region persistence, and bottom-action-bar geometry.

All currently listed inline review threads are resolved. Historical COMMENTED/model/bot reviews are supplementary only and do not satisfy the independent approval requirement.

Exact current identity

• protected base: develop@2c328875e00e86537df3e965170be80532571cad;
• exact contributor head: f705a9589e64ddf4919157ebccce9d897f8ac744;
• exact head tree: 4a5e0f5d6fff0ff4fbf32cf373806cb9ba234195;
• effective diff: .jules/palette.md, app.js, index.html, styles.css, tests/e2e/scopeweave.spec.js, tests/e2e/toast-accessibility.spec.js, tests/unit/toast-accessibility.test.mjs.

Any base or contributor-head movement invalidates exact-head evidence until freshly revalidated. This body is traceability, not merge authority.

Design-system / Storybook / Figma evidence

A fresh current-tree repository search exposes no Figma reference, no Storybook reference, and the current package.json has no Storybook dependency or script. The implementation therefore does not claim paired Figma ↔ Storybook design-authority parity. Under the CWL design-centered commercial policy this UI PR remains non-mergeable until an authoritative paired design surface is linked or established and the current disabled/enabled, focus, screen-reader, responsive, loading/error/empty-state behavior is reconciled against it. Existing CSS and accessibility contracts are preserved rather than inventing a detached design authority inside this PR.

Exact-head hosted evidence

Repository-owned exact-head workflows currently observed as terminal-success include OSV Scanner, SAST Semgrep, Fuzz, Dependency Review, Security Scan and Server Tests, alongside the current accessibility/browser regressions already incorporated into the branch.

Current non-passing evidence is kept explicit rather than folded into green status:

• opencode-review is failure on exact head f705a9589e64ddf4919157ebccce9d897f8ac744 because no authenticated opencode-agent APPROVED or CHANGES_REQUESTED formal review exists for that exact SHA; predecessor or synthetic evidence is not accepted;
• strix is failure on this exact head because the central scan exhausted its provider path with STRIX_PROVIDER_UNAVAILABLE/HTTP 500 and produced no vulnerability report; this is an infrastructure/provider failure, not a source-code pass or source-code finding, and the active central workflow repair lane must not be raced;
• there is no qualifying independent human approval on the current head; and
• queued, skipped, neutral, stale, predecessor-head, author-only, bot/model-only or synthetic evidence remains non-passing wherever applicable.

The live organization ruleset requires one qualifying approving review, stale-review dismissal after push, resolved review threads, and the current central required workflows. OrganizationAdmin bypass exists technically but must not be used.

Merge gate

Do not merge or enable auto-merge until the unchanged exact contributor head is freshly reconciled to protected develop, paired Figma/Storybook design authority is available and reconciled for this UI flow, every applicable repository and organization-required gate is substantively terminal-passing on this exact head, valid current-head findings are zero, and live protection is satisfied by a qualifying independent approval. Do not self-approve, substitute predecessor evidence, count provider-unavailable failures as success, or bypass branch protections.

📝 Walkthrough

Walkthrough

작업이 없으면 내보내기와 간트 차트 버튼을 네이티브 disabled로 설정합니다. 안내 문단과 aria-live 상태 영역을 추가합니다. 클릭 핸들러의 비활성 상태 검사를 제거하고, 빈 상태와 작업 삭제 후의 접근성 동작을 검증합니다.

Changes

작업 의존 액션 접근성 상태

Layer / File(s)	Summary
접근성 계약 및 안내 마크업 .jules/palette.md, index.html, styles.css	aria-disabled와 네이티브 disabled의 사용 기준을 조건별로 갱신했습니다. 작업 의존 액션 도움말과 화면 낭독기용 상태 영역을 추가했습니다.
액션 실행 및 런타임 상태 app.js	작업이 없으면 두 버튼을 네이티브 disabled로 설정하고 도움말을 연결합니다. 작업이 있으면 상태와 연결을 제거합니다. 활성 버튼의 클릭 핸들러는 대상 함수를 직접 호출합니다.
접근성 상태 및 포커스 검증 tests/e2e/toast-accessibility.spec.js, tests/unit/toast-accessibility.test.mjs	빈 상태, 활성 상태, 마지막 작업 삭제 후의 버튼 상태, 안내 문구, live region, 포커스 이동을 검증합니다.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 0d686

The PR adds native disabled behavior for empty-state actions, but the current head does not consistently synchronize the related accessibility guidance, which can fail the accessibility check; a separate concern also remains that numeric zero values may be rendered as empty strings. Merge should wait for these bounded correctness issues to be fixed or explicitly accepted.

Re-check the exact current diff and the buyer-visible empty-state accessibility contract: native disabled plus synchronized aria-disabled, visible recovery helper, aria-describedby linkage, always-in-tree polite status region, focus recovery, and the latest browser-test corrections. Bind any verdict to this exact head/live base. Do not treat predecessor-head, model-only, synthetic-merge, skipped/neutral/status-only evidence as approval, and do not mutate the branch.

@opencode-agent Please review exact current head f705a9589e64ddf4919157ebccce9d897f8ac744 after the accessibility contract reconciliation. Use the authenticated OpenCode dispatch with NVIDIA_NIM_API_KEY; do not use COPILOT_GITHUB_TOKEN, deterministic fallback approval, predecessor-head evidence, or synthetic/model-only approval. Verify native disabled/tab-order behavior, persistent visible recovery copy, aria-describedby, the always-present polite status region, enabled-state transition, responsive empty-state/action-bar geometry, and the current seven-file bounded diff. Publish an APPROVED or CHANGES_REQUESTED formal review explicitly anchored to this exact SHA.

네, 현재 최신 HEAD(f52d093)를 가져와 검증을 완료했습니다. 요구된 빈 상태의 네이티브 disabled, aria-disabled 동기화, 복구 도움말 표시 유지, 라이브 리전 전환 및 초기 상태 처리 등이 모두 정상적으로 동작하며, 최신 modulepreload 추가도 시맨틱이나 성능 회귀 없이 안전하게 처리되었음을 E2E 및 단위 테스트를 통해 최종 확인했습니다.
