# V1 Block 04 — Backlog and Quick Capture

Status: Planned

Purpose: Support low-friction task capture and a unified backlog/wishlist model.

## Chunk 4.1 — Backlog model and filters

Recommended Codex level: medium

Status: Completed

Tasks:

Implement backlog-friendly task metadata:

- unified backlog storage/state
- filter tags or derived filters for inbox, pushed, critical missed, wishlist, stale, no reward set
- sorting keys for priority, reward vs effort, age, project, times pushed

Rules:

- Do not create separate hard backlog sections.
- Use unified backlog with filters/sorts.
- Do not preserve original schedule/order metadata when moved to backlog.

Acceptance criteria:

- Backlog tasks can be filtered by derived category.
- Moving to backlog clears active schedule placement.
- Tests verify original schedule order is not used to restore backlog items.

Execution notes:

- Added `BacklogView` as a read-only projection over the unified task list.
- Added derived backlog filters for inbox, pushed, critical missed, wishlist, stale, and no reward set.
- Added backlog sort keys for priority, reward vs effort, age, project, and times pushed.
- Added `BacklogTag.wishlist` metadata without creating separate hard backlog sections.
- Verified moving to backlog clears active schedule placement and backlog age sorting does not use original schedule order.
- `dart analyze` and `dart test` passed.

## Chunk 4.2 — Quick capture defaults

Recommended Codex level: medium

Status: Completed

Tasks:

Implement quick capture creation rules:

- Title is required.
- Default destination is backlog.
- Priority defaults to medium.
- Reward defaults to notSet.
- Difficulty may default to notSet or medium depending on model decision.
- Project defaults to Inbox/Unsorted.
- Time can remain unset.

Acceptance criteria:

- Test: minimal quick capture creates backlog task.
- Test: neutral defaults are applied.
- Test: reward notSet is preserved distinctly.

Execution notes:

- Updated `Task.quickCapture` to require a non-empty title.
- Default quick capture destination remains backlog.
- Priority now defaults to `PriorityLevel.medium`.
- Reward defaults to `RewardLevel.notSet` and remains distinct from low reward.
- Difficulty defaults to `DifficultyLevel.notSet`.
- Project defaults to `inbox`, and time remains unset.
- Added tests for title validation and neutral defaults.
- `dart analyze` and `dart test` passed.

## Chunk 4.3 — Quick capture schedule checkbox behavior

Recommended Codex level: high

Status: Completed

Tasks:

Implement behavior for `Add to next available schedule slot`:

- When unchecked, task enters backlog.
- When checked, optional scheduling fields become relevant:
  - duration
  - priority
  - reward
  - project
  - flexibility
- If duration is missing, return a validation result or use a documented default.
- Insert into soonest flexible slot using the scheduling engine.

Acceptance criteria:

- Test: unchecked quick capture goes to backlog.
- Test: checked quick capture with duration schedules into next available slot.
- Test: checked quick capture without required scheduling fields is handled predictably.

Execution notes:

- Added `QuickCaptureRequest`, `QuickCaptureResult`, `QuickCaptureStatus`, and `QuickCaptureService`.
- Unchecked quick capture creates a backlog task and does not invoke scheduling.
- Checked quick capture validates duration and flexibility before scheduling.
- Missing duration returns a validation result while preserving the captured backlog task.
- Checked quick capture with duration inserts into the next available flexible slot through `SchedulingEngine.insertBacklogTaskIntoNextAvailableSlot`.
- Added tests for unchecked backlog capture, checked scheduling, and checked validation behavior.
- `dart analyze` and `dart test` passed.

BREAKPOINT: Stop here. Confirm `high` mode before implementing scheduling integration.

## Chunk 4.4 — Backlog staleness marker calculation

Recommended Codex level: low

Tasks:

Implement age/staleness calculation for backlog display:

- Green: 0–7 days by default.
- Blue: 8–30 days by default.
- Purple: 31+ days by default.
- Thresholds must be configurable constants/settings model, not hardcoded everywhere.
- No automatic prompts per stale task.

Acceptance criteria:

- Tests cover fresh, aging, stale, and configurable thresholds.
