 ### Decisions
 
 Key decisions made during v2.0 planning:
+
 - Platform pivot: single-user to multi-user with discovery-first approach
 - External auth provider (self-hosted, open-source) — Logto vs Authentik OPEN decision
 - SQLite to Postgres migration — required by auth provider and multi-user concurrency
 - Structured UGC only — ratings and predefined fields, no freeform text until moderation
 - Separate globalItems table — not a flag on user items table
 - Single-user SQLite mode diverges at v2.0 boundary

+# Phase 18 Plan 05: User Profiles & Public Sharing Client Summary
+
+**Profile edit UI in settings with avatar upload, public profile page with setup listing, and setup visibility toggle with globe icon**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-04-05T11:15:08Z
+- **Completed:** 2026-04-05T11:19:47Z
+- **Tasks:** 3 (2 auto + 1 checkpoint auto-approved)
+- **Files modified:** 9
+
+## What Was Built
+
+### Task 1: Profile hooks and profile edit UI
+- Created `usePublicProfile` hook for fetching public profile data and `useUpdateProfile` mutation hook
+- Created `ProfileSection` component with avatar upload (reuses existing /api/images endpoint), display name input (max 100 chars), bio textarea with character counter (max 500 chars), and save button
+- Added ProfileSection to settings page as first section (visible when authenticated)
+
+### Task 2: Public profile page and setup visibility toggle
+- Created public profile page at `/users/$userId` with avatar, display name (falls back to "User #id"), bio, and grid of public setups
+- Created `PublicSetupCard` component showing setup name and formatted creation date
+- Added isPublic toggle button with globe icon in setup detail action bar
+- Added "Public" badge to SetupCard in list view
+- Updated `useSetups` interfaces and `useUpdateSetup` mutation to support `isPublic` field
+
+### Task 3: Verification (auto-approved)
+- Build succeeds, lint passes
+
+## Commits
+
+| Task | Commit | Message |
+|------|--------|---------|
+| 1 | f120d17 | feat(18-05): add profile hooks and profile edit UI in settings |
+| 2 | a995668 | feat(18-05): add public profile page and setup visibility toggle |
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing] Profile data loading strategy**
+- **Found during:** Task 1
+- **Issue:** Plan suggested reading profile from `auth?.user?.displayName` but /auth/me only returns `{ id }`, not profile fields
+- **Fix:** Used `usePublicProfile(userId)` to fetch profile data separately, with useEffect for form initialization
+- **Files modified:** src/client/components/ProfileSection.tsx
+
+## Known Stubs
+
+None -- all components are wired to real API endpoints.
+
+## Self-Check: PASSED
