+# Phase 30 Plan 02: Hardware Detection UI + 3-Step Wizard Summary
+
+**One-liner:** Three-step onboarding wizard with hardware probe display (GPU/Apple Silicon/CPU-only), three-card mode selector, and settings persistence via PATCH /api/nexus/settings.
+
+## What Was Built
+
+### Task 1: API client, hook, ModeSelector, and HardwareSummaryStep
+- `ui/src/api/hardware.ts` — typed fetch wrappers: `fetchHardwareInfo`, `fetchNexusSettings`, `updateNexusSettings`, plus `HardwareInfo`, `HardwareTier`, `NexusMode`, `NexusSettings` types (local copy — not imported from server)
+- `ui/src/hooks/useHardwareInfo.ts` — `useHardwareInfo(enabled)` hook wrapping `useQuery` with 5-minute staleTime and retry: 1
+- `ui/src/lib/queryKeys.ts` — added `hardware: { info: ["hardware", "info"] as const }` key
+- `ui/src/components/onboarding/ModeSelector.tsx` — three vertical cards with `border-primary bg-primary/5` selected state; modes: Personal AI Assistant, Project Builder, Both (recommended)
+- `ui/src/components/onboarding/HardwareSummaryStep.tsx` — skeleton loading (3 rows), error state (non-destructive copy), and success state with tier-appropriate labels (Unified memory for Apple Silicon, GPU VRAM for GPU tier, System RAM for CPU-only), plus privacy frame for local AI tiers
+
+### Task 2: Wire multi-step wizard
+- `ui/src/components/NexusOnboardingWizard.tsx` refactored from single-step to 3-step wizard
+- Step indicator `Step {step} of 3` shown above content
+- Step 1: hardware detection heading changes from "Detecting your hardware..." to "Your hardware" when probe resolves; HardwareSummaryStep displayed; Continue always enabled
+- Step 2: ModeSelector with "both" pre-selected; Continue and Back buttons
+- Step 3: existing root directory form preserved; Back button added; Get Started submit
+- `updateNexusSettings({ mode: selectedMode })` called after company creation, before navigate — wrapped in try/catch (non-blocking)
+- Reset effect expanded to also reset `step` to 1 and `selectedMode` to "both" on wizard close
+
+## Checkpoint: Awaiting Visual Verification
+
+Task 3 is a `checkpoint:human-verify` — see PLAN.md for how-to-verify steps.
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Known Stubs
+
+None — all data paths are wired. `useHardwareInfo` fetches from `/api/system/providers` (implemented in 30-01). `updateNexusSettings` PATCHes `/api/nexus/settings` (implemented in 30-01).
