Architecture

Cross-cutting architecture decisions and patterns that don’t fit a single feature. See ../overview/architecture.md for the system-level architecture.

• auth/ – Auth subsystem: JWT, rotating refresh tokens, password reset, per-platform token storage, 401 → refresh → retry
• navigation.md – Navigation infrastructure for the shared UI
• build-flavors.md – Android product flavors, composeApp Gradle-property flavors, server env-var modes
• design-system-conventions.md – Token-consumption rules and design-system contract
• offline-and-sync.md – Offline-first / sync architecture (current strategy)
• plan-patterns-and-tradeoffs.md – Draft: patterns and trade-offs reference
• sync-algorithm-design.md – Earlier sync algorithm design (superseded; kept for reference)
