- Shared SQLite plumbing: PRAGMAs (WAL/NORMAL/foreign_keys) and user_version migrations with typed SchemaVersionException - Workspace folder: .ykanban initialization, empty schema with DDL-level constraints, preset column seeding (ResX-driven), exclusive lock file with holder diagnostics - AppData folder: app.db workspace registry (injectable clock), app.json config store with kebab-case JSON names via explicit [JsonProperty]/[EnumMember], nested sections, corrupt-file backup - ResX infrastructure under Assets/Locales (en + zh-Hans) with MSBuild strongly-typed public Resources class - 54 unit tests: DDL constraints, migrations, PRAGMAs, lock exclusivity, config degradation, culture-aware presets
