fix(workspace): explain practice-progress limits with accessible tooltips

[seonghobae]

Buyer-visible outcome

Practice Progress keeps the +/- controls keyboard-focusable at the 0% and 100% boundaries, preserves the action as each button's accessible name, explains the boundary as a separate description, and gives both buttons plus the slider interaction envelope a 44 CSS px target while keeping the visual slider track thin. The shared Base UI tooltip is supplementary; assistive technology receives the limit reason through persistent aria-describedby content.

This is a Workspace/UI accessibility slice only. It does not change practice-progress persistence, rehearsal decision logic, MIR, Active Player, or shared identity contracts.

Exact current identity

• Protected base: develop@314ddeae7b775a4957594b599358c8255617eb2e.
• Branch: palette-tooltips-3326814127791485331.
• Exact head: d839aa9cbdd29735f5e2c8849658c4e975d1c7fe.
• Open / Draft / mergeable.
• Current tree is byte-equivalent to validated semantic head d2cf8db5762c4aa583026aeb758b27a3722e67fb; the five-commit descendant history is preserved and d2cf8db... → d839aa9... has zero file delta.
• Protected-base semantic diff is the same four Workspace-owned files: PracticeProgress.tsx, focused test, EN locale, KO locale.

Every source movement invalidates predecessor checks/reviews. Only the unchanged exact current head may satisfy the verification gate.

Accessibility contract retained

• Boundary controls use aria-disabled plus click guards; aria-disabled is not treated as behavioral disabling by itself.
• The accessible name remains the action (Decrease progress / Increase progress).
• At 0% / 100%, a stable aria-describedby points to a localized persistent reason (practiceProgressAtMin / practiceProgressAtMax).
• Boundary tooltip text combines action + reason for sighted hover/focus users; AT does not depend on tooltip popup timing.
• Decrease/increase buttons use size-11; the slider pointer envelope uses h-11; the visible track remains h-3; the native range input fills the full interaction envelope.
• Current app locale authority remains EN/KO. JA/ZH/VI/ES/DE/FR and versioned translation-ledger acceptance remain product-wide gaps and are not fabricated here.

WCAG 2.2 SC 2.5.8 defines the Level-AA minimum target size and SC 2.5.5 defines the 44×44 CSS px enhanced target objective used by this control. Source/jsdom class assertions are not promoted to browser geometry evidence.

Intervening-delta repair — 2026-09-19

After d2cf8db..., four ordinary descendants (dd6679e... through cc45a298...) again replaced the stronger boundary contract with the generated tooltip-only implementation. Fresh compare showed exactly four semantic regressions:

• removed EN/KO 0% / 100% boundary-reason strings;
• removed persistent aria-describedby reasons from both boundary buttons;
• shrank the +/- targets from 44 CSS px (size-11) back to 32 px (size-8);
• shrank the slider interaction envelope from 44 px (h-11) back to the 12 px visual track and removed the focused target-size regression.

The added TooltipProvider wrappers in the intervening tests did not add a distinct product contract: Tooltip already owns a provider boundary and the stronger current semantic tree exercises the same controls without losing the boundary-reason/target-size assertions.

Repair d839aa9cbdd29735f5e2c8849658c4e975d1c7fe is an ordinary fast-forward descendant of cc45a298.... It restores the four validated blobs from d2cf8db... in one commit, preserves all intervening history, performs no force-push/rebase, and introduces no foreign-owner file.

Verification gate

Fresh exact-head repository/central CI, build, security/SAST, SBOM/supply-chain, coverage and review evidence is required for d839aa9.... Predecessor workflow results and approvals do not transfer. Keep Draft until one unchanged exact head has terminal-success applicable gates, zero valid unresolved findings, and qualifying independent non-author current-head approval.

Browser acceptance still needs mounted Workspace keyboard focus, tooltip hover/focus dismissal/persistence, pointer/touch behavior, boundary click suppression, exact accessible-name/description inspection, effective 44 px hit geometry, clipping/overlap, responsive/400% zoom, forced colors, and Narrator/VoiceOver evidence.

The protected central agent mention router is review-dispatch only. Mention-only activity is not source repair or approval. No self-approval, force-push, destructive rebase, gate weakening, synthetic status, no-op retry commit, or merge on predecessor evidence.

Please review exact head 20e7dea77f6f6c45af0a3c10b244935ef7526b71 only. Focus on PracticeProgress accessible-name/description semantics, aria-disabled click suppression, tooltip behavior, EN/KO boundary copy, and whether the closed #1156 valid delta has been completely succeeded without carrying its inaccurate disabled/title premise. Review evidence only; do not treat this mention as source repair.

요청하신 대로, test_supply_chain_policy.py 등 리뷰 외 범위의 포맷 변경을 취소하고 완전히 이전 상태로 되돌렸습니다 (git restore 사용). PracticeProgress 컴포넌트 내 aria-disabled에 대한 커스텀 툴팁이 렌더링되도록 수정된 내용만 반영하였으며, 관련 코드는 정상 작동을 확인했습니다 (테스트 및 빌드 에러 없음). 코드는 리뷰 봇(opencode-agent)에서 요청한 사항만 포함하여 다시 서브밋하겠습니다.
