Add requirements specification v2.1 - production-ready version
...
This v2.1 represents comprehensive engineering improvements based on
three expert reviews and technical feasibility research (2026 latest tech stack).
Major improvements over v2.0:
**Data Consistency** ⭐
- wrong_count completely driven by attempts (no manual updates)
- Enforced rule: any "correct/wrong/unknown" action must create an attempt
- Provides rebuild_wrong_counts repair tool
**Offline Architecture Clarification** ⭐
- Online: PostgreSQL FTS + pg_jieba
- Offline: SQLite FTS5 + trigram tokenization
- Event Sourcing sync strategy (incremental action logs)
- Outbox queue + idempotency + conflict resolution
**FSRS Replaces SM-2** ⭐
- Using dart-fsrs v2.0.0 (official package)
- More scientific than SM-2 (adopted by Anki)
- Boundary conditions: ease_factor[1.3,2.8], max_interval=90 days
- Anti-gaming mechanisms (prevent same-day double attempts)
**Multi-question Segmentation Strategy** ⭐
- P0 (MVP): Manual box selection + intelligent hints (stable)
- P1 (Week 5-8): Auto-segmentation via PP-DocLayoutV3
- "Puzzle-style adjustment": drag boundaries with auto-snap
- Significantly reduces MVP risk (4-week delivery)
**Strict KPI Metrics** ⭐
- Cohort definition: Week 1 questions tracked to Week 4
- "Second review" definition: ≥24 hours interval, review_mode='daily_review'
- "Heavy wrong" definition: attempts wrong ≥3 on different dates
- All metrics aggregatable from attempts/review_sessions tables
**Latest Tech Stack (2026)** ⭐
- PP-OCRv5 (May 2025, +13% accuracy)
- PP-FormulaNet_plus-M (Chinese formula BLEU 89.76%)
- PP-DocLayoutV3 (Jan 2026, non-planar document support)
- PostgreSQL + pg_jieba (online FTS)
- SQLite FTS5 (offline FTS)
- FSRS via dart-fsrs v2.0.0
- pHash image fingerprinting + TF-IDF text similarity
**UX Optimizations** ⭐
- Anti-cheating: 3-second delay or key value input for "Got it" button
- Anti-frustration: Show hints/tips before full answer on "Don't know"
- Puzzle-style adjustment for manual question segmentation
- pHash first-pass deduplication (instant, OCR-error proof)
**Gamification Prep** ⭐
- Database schema reserves: points, current_streak, longest_streak
- badges and user_badges tables
- P2 implementation ready
**MVP Degradation Paths** ⭐
- Every P0 feature has minimum viable standard defined
- Clear fallback options if auto-features fail
- 4-week delivery risk significantly reduced
Addresses all critical feedback from:
- Expert Review 1 (S-grade): UX details, sync strategy, gamification
- Expert Review 2 (Tech feasibility): Data consistency, offline arch, MVP scope
- Expert Review 3 (Tech research): Latest 2026 tech stack

Add requirements specification v2.0 based on expert reviews
...
This v2.0 version represents a major architectural redesign based on
comprehensive reviews from Claude Opus 4.6, ChatGPT 5.2 Pro, and Gemini 3 Pro.
Key improvements:
- Core philosophy shift from "error management tool" to "learning efficiency improvement system"
- Added spaced repetition system (SuperMemo SM-2 algorithm) as P0 priority
- Added practice/self-test mode with retrieval practice
- Added structured error cause taxonomy system
- Technical stack optimizations (Elasticsearch → PostgreSQL FTS for MVP)
- New database tables: attempts, error_tags, review_sessions
- Learning effectiveness KPIs and acceptance criteria
- Comprehensive exception handling section
- Risk mitigation strategies
Addresses all critical feedback regarding learning efficiency mechanisms,
behavioral change support, and MVP scope optimization.
