Onboarding workspace [UI]

# Onboarding workspace `[UI]`

The domain-genesis surface: a full-screen workspace with a progress sidebar and a center step container. Six steps carry a *constellation of drafts* from an idea to extracted, maintained Domains. Two steps (Capture, Maintain) let you move between drafts in any order; the rest are linear.

- **The sidebar is the spine.** `ONBOARDING_STEPS` drives the numbered rail (step *n* of 6); Capture and Maintain expose a **per-draft switcher** below it because both operate over every draft Domain, in any order. The delete control tears down the whole onboarding (answers, Graph, corpus).
- **Capture is a split-pane.** An interview chat on one side, the accumulating corpus review on the other — the two expandable panels track focus per draft. This is the ideal grounding path: paid Research (public) + interview (private) → corpus → accept → expert corpus.
- **Build is background + resumable.** Creating the Constellation and extracting each accepted corpus runs in the background — you can leave and return. Deleting a Constellation/Domain elsewhere makes the step offer to rebuild it.
- **The whole flow is also drivable headless.** The same steps are a Tier-2 op family, so a chat can run all six (build/automation execute immediately).

**Where it lives:** `src/features/onboarding/` — `OnboardingWorkspaceView.tsx` · `OnboardingSidebar.tsx` · `OnboardingSteps.tsx` · `steps/{IdeaStep,CaptureStep,GraphStep}.tsx` · `SynthesisStep.tsx` · `GraphStudio.tsx`. Step model: `src/types/domain/onboarding.ts` + `src/lib/core/onboarding.ts`. Background runner: [onboarding](../flows/onboarding.md) flow · [extraction-pipeline](../flows/extraction-pipeline.md).
