v0.3.0 — Phase β-2 Study-Loop
Voller Lern-Flow mit Web-Parität: fällige Karten via /reviews/due laden, flip + rate (4 Buttons + Haptic), Grades via Offline-Queue ans Server-FSRS schicken. - Card/Review/DueReview DTOs mit snake_case + camelCase-deckId- Sonderfall im embedded card-Subobjekt - CardType-Enum (alle 7 Typen), Rating-Enum mit deutschen Labels - Cloze-Helper 1:1-Port aus cards-domain (extractClusterIds, subIndexCount, clusterId, renderPrompt/Answer, hint) - CardsAPI.dueReviews(deckId:) + gradeReview(cardId,subIndex,rating,reviewedAt) - PendingGrade SwiftData-Model + GradeQueue (FIFO-Drain, originaler Timestamp bleibt, bei Netzfehler in Queue, Retry beim nächsten Drain) - StudySession @Observable State-Machine - CardRenderer für basic, basic-reverse, cloze; Placeholder für image-occlusion/audio-front/typing/multiple-choice (β-3/β-4) - RatingBar mit UIImpactFeedbackGenerator (medium/heavy) - StudySessionView per NavigationLink aus DeckListView - 9 neue Tests (Cloze: 8, Review-Decoding: 3), insgesamt 17 grün Server-authoritative FSRS bleibt — kein ts-fsrs-Port. Endurance-Test auf realem Gerät steht aus (siehe PLAN.md). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
