# Task: Enforce basic approval modes

## Feature

`docs/FEATURES/approval-workflow.md`

## Goal

Apply workspace approval mode configuration to the existing single-step approval request flow.

## Scope

- Prevent approval requests when workspace approval mode is `None`.
- Keep the current approval request endpoints as the one-step compatibility flow for `Optional` and `Required`.
- Block manual moves to `Approved` or `Scheduled` for `Required` workspaces until an approval request has an approved decision.
- Leave `Optional` approval non-blocking.
- Apply the saved "schedule posts automatically on approval" option when a final approval decision is recorded.

## Constraints

- Do not implement workflow recalculation in this task.
- Do not implement multi-level step configuration in this task.
- Do not implement locking behavior, reminder jobs, comments, mentions, reopening, or magic links in this task.
- Do not replace the existing approval request data model in this task.

## Done When

- [x] Approval mode `None` does not create approval requests.
- [x] Approval mode `Optional` allows manual approval/scheduling without approval decisions.
- [x] Approval mode `Required` blocks manual approval/scheduling until a completed approval decision exists.
- [x] Approved decisions move content to `Scheduled` when auto-scheduling is enabled and the content item has a planned publish date.
- [x] Backend tests pass.
