+
+# [H] Handover — Package DD-XXX and Hand Off to BMad
+
+**Goal:** Package a complete testable flow into a Design Delivery and hand off to development.
+
+**When to use:** A scenario flow is fully designed, all specifications exist, and you are ready to hand off to BMad for implementation.
+
+---
+
+## INITIALIZATION
+
+Read design log at `{output_folder}/_progress/00-design-log.md` before starting.
+
+---
+
+## STEPS
+
+Execute steps in `./steps-h/`:
+
+| Step | File | Purpose |
+|------|------|---------|
+| 01 | step-01-detect-completion.md | Verify flow is complete and testable |
+| 02 | step-02-create-delivery.md | Package into DD-XXX Design Delivery |
+| 03 | step-03-create-test-scenario.md | Define validation tests |
+| 04 | step-04-handoff-dialog.md | Structured handoff conversation with BMad |
+| 05 | step-05-hand-off.md | Official handoff to BMad |
+| 06 | step-06-continue.md | Return to design or next flow |
+
+**Reference data:**
+- `./data/delivery-templates.md`
+- `./data/handoff-dialog-scripts.md`
+- `./data/design-deliveries-guide.md`
+
+---
+
+## AFTER COMPLETION
+
+1. Append a progress entry to `{output_folder}/_progress/00-design-log.md` under `## Progress`:
+   `### [date] — Design Delivery: [what was packaged]`
+2. Suggest next action: Phase 5 prototyping or next scenario
