+# ClaudeDo.Data
+
+Shared data layer: models, repositories, SQLite infrastructure, and git operations.
+
+## Models
+
+- **TaskEntity** — Id, ListId, Title, Description, Status (Manual|Queued|Running|Done|Failed), ScheduledFor, Result, LogPath, timestamps, CommitType
+- **ListEntity** — Id, Name, WorkingDir, DefaultCommitType, CreatedAt
+- **TagEntity** — Id (autoincrement), Name (unique)
+- **WorktreeEntity** — TaskId (PK, 1:1 with task), Path, BranchName, BaseCommit, HeadCommit, DiffStat, State (Active|Merged|Discarded|Kept)
+
+## Repositories
+
+All repositories use raw parameterized SQL via `Microsoft.Data.Sqlite`. Each method opens its own connection — no Unit of Work.
+
+- **TaskRepository** — CRUD, status transitions (`MarkRunningAsync`, `MarkDoneAsync`, `MarkFailedAsync`), `GetNextQueuedAgentTaskAsync` (queue polling), `GetEffectiveTagsAsync` (union of task + list tags), `FlipAllRunningToFailedAsync`
+- **ListRepository** — CRUD, tag junction management
+- **TagRepository** — `GetOrCreateAsync` (idempotent)
+- **WorktreeRepository** — CRUD, `UpdateHeadAsync`, `SetStateAsync`
+
+## Infrastructure
+
+- **SqliteConnectionFactory** — creates connections, applies WAL mode once, enforces foreign keys via PRAGMA
+- **SchemaInitializer** — applies embedded `schema/schema.sql` idempotently (IF NOT EXISTS, INSERT OR IGNORE)
+- **Paths** — expands `~` and `%USERPROFILE%`, resolves relative paths. App root: `~/.todo-app`
+- **AppSettings** — loads `~/.todo-app/ui.config.json` (DbPath, SignalRUrl)
+
+## Git
+
+- **GitService** — async wrapper around git CLI (ProcessStartInfo, no shell). Operations: worktree add/remove, add all, commit (stdin for message), merge ff-only, rev-parse, diff-stat, has-changes, is-git-repo
+
+## Schema
+
+6 tables: `lists`, `tasks`, `tags`, `list_tags`, `task_tags`, `worktrees`. See `schema/schema.sql`. Seed data: tags "agent" and "manual".
+
+## Conventions
+
+- Enum <-> string mapping via explicit `ToDb()`/`FromDb()` static methods on each enum
+- Primary keys are `init`-only strings (GUIDs assigned at creation)
+- Nullable fields use `DBNull.Value` checks
+- All methods are async with CancellationToken where applicable
