+# Phase 18 Plan 01: Schema Foundations Summary
+
+**Global items table, item-global links, user profile columns, setup visibility, Zod schemas, and 18-item bikepacking seed catalog**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-04-05T10:57:03Z
+- **Completed:** 2026-04-05T10:59:44Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- Added globalItems and itemGlobalLinks tables to Postgres schema with proper FK constraints
+- Extended users table with displayName, avatarUrl, bio profile fields
+- Extended setups table with isPublic boolean for public sharing
+- Created Zod validation schemas and TypeScript types for all new entities
+- Built 18-item bikepacking gear seed catalog with real product data
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Schema tables and column additions** - `8265703` (feat)
+2. **Task 2: Zod schemas, types, and seed data** - `81b70a7` (feat)
+
+## Files Created/Modified
+- `src/db/schema.ts` - Added boolean import, globalItems table, itemGlobalLinks table, users profile columns, setups isPublic
+- `src/shared/schemas.ts` - Added searchGlobalItemsSchema, linkItemSchema, updateProfileSchema; updated setup schemas with isPublic
+- `src/shared/types.ts` - Added GlobalItem, ItemGlobalLink, SearchGlobalItems, LinkItem, UpdateProfile types
+- `src/db/global-items-seed.json` - 18 bikepacking gear items across bags, shelters, sleep systems, cooking, hydration, lighting, racks, accessories
+- `drizzle-pg/0001_tough_boomerang.sql` - Migration for all schema changes
+
+## Decisions Made
+- Global items category stored as text (not FK to categories) since global items are hobby-agnostic and not user-scoped
+- itemGlobalLinks uses unique constraint on itemId ensuring one-to-one mapping from user item to global item
+- Seed data uses real product names and approximate specs for realistic development/testing
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Schema foundation complete for all Phase 18 plans
+- Plan 18-02 (global items service/routes) can proceed with globalItems table and search schema
+- Plan 18-03 (profiles/visibility) can proceed with user profile columns and updateProfileSchema
+- Migration file ready for deployment
