# Phase 2 Planning Summary
|
|
|
|
## Overview
|
|
Phase 2: Household Creation & Invites - Enable multi-user collaboration through invitation-based household management.
|
|
|
|
## Phase Analysis
|
|
|
|
### Requirements Coverage
|
|
- **SHARE-01:** User can create a household with a name → Plan 01 (Data Models) + Plan 04 (Create UI)
|
|
- **SHARE-02:** User can generate invite codes for household members → Plan 01 (Models) + Plan 03 (Use Cases) + Plan 04 (Invite Dialog)
|
|
- **SHARE-03:** User can join existing household via invite code → Plan 01 (Models) + Plan 03 (Use Cases) + Plan 05 (Join Page)
|
|
- **SHARE-04:** User can choose to merge inventories, keep separate, or use invitee's inventory when joining → Addressed in Plan 01 (Business Logic) - inventory merging logic deferred to Phase 4 when inventory system exists
|
|
- **SHARE-05:** Items with same name but different expiration dates from merged inventories are tracked separately → Database schema in Plan 02 supports this through unique constraints on household_id + item_id
|
|
|
|
### Technical Challenges Addressed
|
|
1. **Multi-tenant isolation** via Row-Level Security policies (Plan 02)
|
|
2. **Real-time synchronization** through Supabase Realtime triggers (Plan 02)
|
|
3. **Invite code generation** with collision detection and 30-day expiry (Plan 01 + 03)
|
|
4. **Optimistic locking** for concurrent household operations (Plan 02 RLS)
|
|
5. **State management** integration with existing auth system (Plan 03 + 06)
|
|
|
|
## Wave Structure
|
|
|
|
| Wave | Plans | Focus | Parallel Execution |
|
|
|------|-------|--------|-------------------|
|
|
| 1 | 01, 02 | Foundation: Data models + Database schema | ✅ Parallel (independent concerns) |
|
|
| 2 | 03 | Business logic and state management | 🔄 Sequential (depends on 01, 02) |
|
|
| 3 | 04, 05 | UI components and pages | ✅ Parallel (different UI flows) |
|
|
| 4 | 06 | Integration with navigation and auth | 🔄 Sequential (depends on UI ready) |
|
|
|
|

|
|
- Consistent error handling and loading states
|
|
|
|
### Plan 05: Household Management UI

|
|
**Focus:** Complete household management experience
|
|
**Key Deliverables:**
|
|

|
|
- Household list page as management hub
|
|
- Empty states and navigation flows
|

|
## Quality Gates
|
|
|
|
### Must-Haves Verification
|
|
✅ **Truths Derived:** All 5 success criteria mapped to observable behaviors
|
|
✅ **Artifacts Identified:** 23 specific files with clear purposes
|
|
✅ **Key Connections Mapped:** 12 critical integration points documented
|
|
✅ **Dependencies Correct:** Database → Repository → Use Cases → UI → Integration
|
|
✅ **Autonomy Maintained:** Only Plan 06 has user interaction checkpoints
|
|
|
|
### Scope Estimation
|
|
✅ **Context Budget:** Each plan targets 40-50% context usage
|
|
✅ **Task Sizing:** 2-3 tasks per plan, 15-60 minutes each
|
|
✅ **Wave Optimization:** Maximum parallelism where dependencies allow
|
|
✅ **No Scope Creep:** Focused strictly on SHARE-01 through SHARE-05
|
|
|
|
## Integration Points
|
|
|
|
### Critical Dependencies
|
|
- **Plan 01 → Plan 03:** Repository interface required for use cases
|
|
- **Plan 02 → Plan 03:** Database schema required for repository implementation
|
|
- **Plan 04 → Plan 05:** UI components required for management pages
|
|
- **Plan 05 → Plan 06:** Complete UI required for navigation integration
|
|
|
|
### Research Integration
|
|
✅ **Multi-tenant isolation:** RLS policies per research recommendations
|
|
✅ **Real-time sync:** Supabase Realtime triggers implemented
|
|
✅ **Invite code security:** 8-character codes with collision detection
|
|
✅ **Error handling:** Comprehensive exception hierarchy per research findings
|
|
|
|
## Post-Planning Notes
|
|
|
|
### Technical Decisions Made
|
|
1. **Clean Architecture:** Following Phase 1 patterns for consistency
|
|
2. **Riverpod State Management:** Reusing auth provider patterns
|
|
3. **RLS at Database Layer:** Research-validated approach for multi-tenant security
|
|
4. **8-Character Invite Codes:** Balances usability with collision probability
|
|
5. **Database Functions:** Efficient invite validation and household operations
|
|
|
|
### Future Phase Implications
|
|
- **Phase 3 (Barcode):** Household context will be available for item creation
|
|
- **Phase 4 (Manual Entry):** Inventory merging logic will be implemented
|
|
- **Phase 8 (Usage):** Household membership data supports analytics
|
|
- **Phase 11 (Web App):** Household isolation supports multi-platform sync
|
|
|
|
### Risk Mitigations
|
|
- **Invite Code Collisions:** Database function handles collision detection
|
|
- **Concurrent Joins:** Unique constraints and RLS prevent conflicts
|
|
- **State Synchronization:** Provider integration ensures auth ↔ household sync
|
|
- **Navigation Complexity:** Route guards handle all household states
|
|
|
|
