# Description

**Review ref**: W-4 (Warning)
**Files affected**: `docs/architecture/schemas.md`, `docs/architecture/cost-benefit.md`

The `TaskStatusEnum` values are never explicitly listed — just "same pattern for TaskImpact, TaskLevel, TaskPriority, TaskStatus." Also, `cost-benefit.md` references `includeCompleted: false` but doesn't define which status value(s) constitute "completed."

Define TaskStatusEnum values explicitly. Specify which status(es) the `includeCompleted` option treats as "completed." This blocks implementation of both the schema and the workflowCost function.
