# Requirements: GearBox v2.0 Platform Foundation

**Defined:** 2026-04-03
**Core Value:** Help people make better gear decisions — discover what others use, compare real-world data, and see how a potential buy affects your setup before committing.

## v2.0 Requirements

Requirements for this milestone. Each maps to roadmap phases.

### Database Migration

- [ ] **DB-01**: Application runs on PostgreSQL instead of SQLite
- [ ] **DB-02**: All service functions use async database operations
- [ ] **DB-03**: Test infrastructure uses PGlite instead of bun:sqlite in-memory databases
- [ ] **DB-04**: Existing SQLite data can be migrated to Postgres via a one-time script
- [ ] **DB-05**: Docker Compose provides Postgres for local development

### Authentication

- [ ] **AUTH-01**: User can register an account via external OIDC auth provider
- [ ] **AUTH-02**: User can log in via external auth provider and access their data
- [ ] **AUTH-03**: API keys remain functional for programmatic access (MCP, scripts)
- [ ] **AUTH-04**: Auth provider runs self-hosted alongside the application
- [ ] **AUTH-05**: E2E tests authenticate via API keys without depending on the auth provider

### Multi-User Data Model

- [ ] **MULTI-01**: Every item, category, thread, and setup is owned by a specific user
- [ ] **MULTI-02**: User can only see and modify their own data (cross-user isolation)
- [ ] **MULTI-03**: Categories use composite unique constraint (userId + name)
- [ ] **MULTI-04**: Existing data is assigned to the original user during migration
- [ ] **MULTI-05**: MCP tools operate within the authenticated user's scope
- [ ] **MULTI-06**: Settings are per-user rather than global

### Image Storage

- [ ] **IMG-01**: Images are stored in MinIO (S3-compatible) instead of local filesystem
- [ ] **IMG-02**: Existing uploaded images are migrated to MinIO
- [ ] **IMG-03**: Image upload and retrieval work through the new storage layer
- [ ] **IMG-04**: Docker Compose provides MinIO for local development

### Global Item Database

- [x] **GLOB-01**: A global item catalog exists with brand, model, category, manufacturer specs, and image
- [x] **GLOB-02**: Global catalog is seeded with initial items from manufacturer data
- [x] **GLOB-03**: User can search the global catalog by name or brand
- [x] **GLOB-04**: User can link a personal collection item to a global catalog entry
- [x] **GLOB-05**: Global item pages show basic info and owner count

### User Profiles & Sharing

- [ ] **PROF-01**: User has a profile with display name, avatar, and bio
- [ ] **PROF-02**: User can view their own public profile page
- [ ] **PROF-03**: User can set a setup as public or private
- [ ] **PROF-04**: Public setups are viewable by anyone without authentication
- [ ] **PROF-05**: Public profile page lists the user's public setups

## Future Requirements

Deferred to future milestones. Tracked but not in current roadmap.

### Reviews & Ratings

- **REV-01**: User can rate a global item with an overall star rating
- **REV-02**: User can rate a global item on predefined dimensions (durability, value, etc.)
- **REV-03**: Item detail pages show average ratings from all reviewers

### Discovery

- **DISC-01**: User can browse recently shared public setups
- **DISC-02**: User can browse recently reviewed items
- **DISC-03**: User can browse popular gear by owner count

### Aggregation

- **AGG-01**: Item detail pages show crowd-verified specs (manufacturer vs community-measured weight)
- **AGG-02**: Item detail pages show which setups include this item
- **AGG-03**: Setup composition insights ("commonly paired with")

### Social

- **SOCL-01**: User can fork/copy a public setup as a template
- **SOCL-02**: Planning thread candidates can link to global items for auto-populated specs
- **SOCL-03**: User can follow other users
- **SOCL-04**: User can view an activity feed of followed users' content

### Content Moderation

- **MOD-01**: User can submit freeform text reviews
- **MOD-02**: User can report inappropriate content
- **MOD-03**: Admin can review and act on reported content

## Out of Scope

Explicitly excluded. Documented to prevent scope creep.

| Feature | Reason |
|---------|--------|
| Freeform text reviews | Requires moderation infrastructure not yet built |
| Comments on setups | Moderation burden, notification system needed |
| User-to-user messaging | High moderation burden, not core to discovery |
| Wiki-style open item editing | Quality control risk; structured contributions only |
| Marketplace / buy-sell | Payment processing, fraud, legal liability |
| AI gear recommendations | Training data requirements, hallucination risk |
| Gamification (badges, points) | Incentivizes quantity over quality |
| Instagram-style infinite scroll | Engagement-maximizing conflicts with utility focus |
| Price tracking / deal alerts | Requires scraping, fragile, legal gray area |
| Mobile native app | Web-first, responsive design sufficient |
| Real-time collaborative setups | WebSocket complexity for niche use case |
| Maintaining SQLite single-user mode | Platform features irrelevant for solo use; diverged at v2.0 |
| Redis infrastructure | Not needed at v2.0 scale; auth provider (Logto) doesn't require it |
