-| Plan exists and reachable? | ✅ | `docs/superpowers/plans/2025-11-01-espiritismo-rag-system.md` |
-| Spec exists and reachable? | ✅ | `docs/superpowers/specs/2025-11-01-espiritismo-rag-system-design.md` |
-| Global Constraints present? | ✅ | CPU-only, 8GB RAM, ~5GB storage, Docker, etc. |
-| Tasks independent? | ⚠️ | Many tasks touch common code (embedding, PDF processing) - use batching for small same-shape work |
-| Worktree isolated? | ✅ | Using existing workspace at `lab/espiritismo` |
-
-**Rulings:**
-- Ruling: Use batching for small same-shape work (Tasks 2, 4, 6, 7) — they touch common utilities and can be dispatched together to avoid context pollution. Costs: additional coordination but keeps context clean. Correctness: reduces context churn and improves parallelization.
