 ### Phase 3: TodoWrite Generation
 **Applies to**: Both normal and resume modes (resume mode entry point)
 
+**Step 0: Update Session Status to Active**
+Before generating TodoWrite, update session status from "planning" to "active":
+```bash
+# Update session status (idempotent - safe to run if already active)
+jq '.status = "active" | .execution_started_at = (.execution_started_at // now | todate)' \
+  .workflow/active/${sessionId}/workflow-session.json > tmp.json && \
+  mv tmp.json .workflow/active/${sessionId}/workflow-session.json
+```
+This ensures the dashboard shows the session as "ACTIVE" during execution.
+
 **Process**:
 1. **Create TodoWrite List**: Generate task list from TODO_LIST.md (not from task JSONs)
    - Parse TODO_LIST.md to extract all tasks with current statuses
