# ClaudeDo.Data

Shared data layer: models, repositories, SQLite infrastructure, and git operations.

## Models

- **TaskEntity** — Id, ListId, Title, Description, Status (`Idle|Queued|Running|WaitingForChildren|WaitingForReview|Done|Failed|Cancelled`), PlanningPhase (`None|Active|Finalized` — parent-only), BlockedByTaskId (nullable FK to predecessor in a chain), ScheduledFor, Result, ReviewFeedback (nullable; reviewer's rejection comment, consumed and cleared by the runner on the next re-run), LogPath, timestamps, CommitType, Model / SystemPrompt / AgentPath / MaxTurns (nullable overrides), IsStarred, IsMyDay, Notes, ParentTaskId, PlanningSessionId, PlanningSessionToken, PlanningFinalizedAt, CreatedBy. Legacy values `Manual`/`Planning`/`Planned`/`Draft`/`Waiting` were retired; existing rows backfill automatically via the `RetireLegacyTaskStatus` migration.
- **ListEntity** — Id, Name, WorkingDir, DefaultCommitType, CreatedAt
- **ListConfigEntity** — ListId (PK, 1:1 with list), Model, SystemPrompt, AgentPath, MaxTurns (all nullable)
- **WorktreeEntity** — TaskId (PK, 1:1 with task), Path, BranchName, BaseCommit, HeadCommit, DiffStat, State (Active|Merged|Discarded|Kept)
- **TaskRunEntity** — per-run record (session_id, tokens, turns, result, structured output, exit code, log path)
- **PrimeScheduleEntity** — Id, Days (`[Flags] PrimeDays` weekday bitmask, stored as `days_of_week` int), TimeOfDay, Enabled, LastRunAt, PromptOverride, CreatedAt. Recurs on the selected weekdays; no date range.
- **DailyNoteEntity** — Id, Date (DateOnly), Text, SortOrder, CreatedAt → table `daily_notes`
- **WeekReportEntity** — Id, StartDate/EndDate (DateOnly), Markdown, GeneratedAt → table `week_reports`, unique index on (start_date, end_date)
- **TaskAttachmentEntity** — Id, TaskId (FK to tasks, ON DELETE CASCADE), FileName, ByteSize, CreatedAt → table `task_attachments`
- **AppSettingsEntity** also carries `ReportExcludedPaths` (string?, JSON array of excluded path prefixes, column `report_excluded_paths`), `StandupWeekday` (int DayOfWeek, default Wednesday, column `standup_weekday`), and `DailyPrepMaxTasks` (int, default 5, column `daily_prep_max_tasks` — hard cap on how many open tasks the daily-prep / "Prime Claude" feature may place in MyDay)
- **SubtaskEntity**, **AppSettingsEntity**, **AgentInfo** — existing helpers / settings / record for scanned agent files

## Repositories

All repositories use EF Core LINQ queries via `ClaudeDoDbContext`. The atomic `Queued -> Running` claim lives in the Worker's `QueuePicker` (uses `FromSqlRaw`), not here.

- **TaskRepository** — CRUD, planning helpers (`CreateChildAsync`, `SetPlanningStartedAsync`, `DiscardPlanningAsync`, `UpdateChildAsync`), `UpdateAgentSettingsAsync` (model / system-prompt / agent-path overrides). Status-mutation primitives `MarkRunningAsync` / `MarkDoneAsync` / `MarkFailedAsync` / `FlipAllRunningToFailedAsync` are `internal` and called only by `TaskStateService` in the worker. `CreateChildAsync` produces children with `Status=Idle, PlanningPhase=None`; once their parent's `PlanningPhase` becomes `Finalized`, the chain coordinator queues them.
- **ListRepository** — CRUD, `GetConfigAsync` / `SetConfigAsync` (upsert) / `DeleteConfigAsync` for `list_config`
- **WorktreeRepository** — CRUD, `UpdateHeadAsync`, `SetStateAsync`
- **TaskRunRepository**, **SubtaskRepository**, **AppSettingsRepository**
- **DailyNoteRepository** — `ListByDayAsync`, `ListBetweenAsync`, `AddAsync`, `UpdateAsync`, `DeleteAsync`
- **WeekReportRepository** — `GetByRangeAsync`, `UpsertAsync`
- **TaskAttachmentRepository** — `AddAsync`, `UpdateAsync`, `GetAsync(taskId, fileName)`, `ListByTaskIdAsync`, `DeleteAsync(taskId, fileName)`, `DeleteAllForTaskAsync`

## Infrastructure

- **ClaudeDoDbContext** — EF Core DbContext; configured with WAL mode and foreign keys via `UseSqlite` options
- **IDbContextFactory<ClaudeDoDbContext>** — registered in DI; used by singleton consumers (e.g. Worker hosted service)
- **Paths** — expands `~` and `%USERPROFILE%`, resolves relative paths. App root: `~/.todo-app`
- **AppSettings** — loads `~/.todo-app/ui.config.json` (DbPath, SignalRUrl)
- **AttachmentStore** — dependency-free file store; default root `~/.todo-app/attachments/<taskId>/`. `SaveAsync` enforces a 5 MB cap and path-traversal/containment guard. Also exposes `DeleteFile`, `DeleteTaskDir`, `TaskDir`, `Root`, and `EnumerateTaskIds` (used by the worker orphan sweep). Attachment files live outside git worktrees intentionally.

## Git

- **GitService** — async wrapper around git CLI (ProcessStartInfo, no shell). Worktree ops (add — serialized to avoid a commondir race —, remove, prune, list paths for branch), branch ops (current, list local, checkout, delete), staging/commit (status porcelain, add-all, add-path, commit via stdin), diffs (working tree, branch vs base, commit range `base..head` — used to show a merged task's diff after the worktree is gone —, per-file, diff-stat, committed files, has-changes), merge (ff-only, no-ff, abort, mid-merge detection, conflicted files), `PreviewMergeAsync` (non-destructive mergeability check via `git merge-tree --write-tree`), `CountChangedFilesAsync`, rev-parse, is-git-repo

## Schema

Tables: `lists`, `tasks`, `worktrees`, `list_config`, `task_runs`, `subtasks`, `app_settings`, `prime_schedules`, `daily_notes`, `week_reports`, `task_attachments`. Managed by EF Core migrations in the `Migrations/` folder. The `tasks` table holds `status`, `planning_phase` (default `none`), and `blocked_by_task_id` (FK to `tasks.id`, `ON DELETE SET NULL`). Migration `WeeklyReport` added `daily_notes`, `week_reports`, and the two new `app_settings` columns. Migration `DailyPrepMaxTasks` added the `daily_prep_max_tasks` column to `app_settings` (no new tables). Migration `AddTaskAttachments` created the `task_attachments` table. `TaskRepository.DeleteAsync` and `ListRepository.DeleteAsync` also delete the on-disk attachment dir(s) via an optional `AttachmentStore` ctor param (defaults to the production store).

## Conventions

- Enum <-> string mapping via EF Core `ValueConverter` (configured in `IEntityTypeConfiguration<T>`)
- Entity configurations live in the `Configuration/` folder
- Primary keys are `init`-only strings (GUIDs assigned at creation)
- All methods are async with CancellationToken where applicable
