## Validation Rules

| Rule | Check | Error |
|------|-------|-------|
| Unique IDs | No duplicate `id` values | "Duplicate task ID: {id}" |
| Valid deps | All dep IDs exist in tasks | "Unknown dependency: {dep_id}" |
| No self-deps | Task cannot depend on itself | "Self-dependency: {id}" |
| No circular deps | Topological sort completes | "Circular dependency detected" |
| exec_mode valid | Value is `csv-wave` or `interactive` | "Invalid exec_mode: {value}" |
| Role valid | role ∈ {explorer, scanner, diagnoser, designer, implementer, tester} | "Invalid role: {role}" |
