Step 5/17 av Playground v3-leveransen (Session 2, Wave 2).
5 grouped sections (organization/technology/security/architecture/business)
rendered with Tier 3 .form-progress sidebar and .expansion components per
group. Validation via .error-summary with click-to-focus links.
ONBOARDING_SCHEMA mirrors agents/onboarding-agent.md Phase 1-5 (18 fields
total). commitOnboarding() writes to state.shared.<group>.<field> via
Proxy → throttled IDB/localStorage write. Re-onboard is just navigate
back to onboarding — pre-fills from state automatically.
Verified via vm sandbox: bootstrap auto-routes to onboarding when no
org.name, commitOnboarding produces >=5 keys in shared.organization,
validation catches required-empty (2) and accepts filled (0).
Surface routing: showSurface() toggles [hidden] across data-surface
sections. scheduleRender batches via queueMicrotask. Action router
dispatches data-action attributes to ACTIONS map. README/CLAUDE.md-update
deferred til Step 17 (Session 5).
