# Requirements: GearBox v2.1 Public Discovery

**Defined:** 2026-04-09
**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.

## v2.1 Requirements

Requirements for Public Discovery milestone. Each maps to roadmap phases.

### Public Access

- [x] **PUBL-01**: User can browse the global item catalog without logging in
- [x] **PUBL-02**: User can view public setups without logging in
- [x] **PUBL-03**: User can view user profiles without logging in
- [x] **PUBL-04**: Anonymous visitors see the landing page without auth spinner or redirect
- [x] **PUBL-05**: Login is only required when user attempts to create/edit/delete their own data

### Discovery

- [x] **DISC-01**: Landing page displays an always-visible catalog search bar at the top
- [x] **DISC-02**: Landing page shows a feed of popular setups below the search
- [x] **DISC-03**: Landing page shows recently added catalog items
- [x] **DISC-04**: Landing page shows trending categories
- [x] **DISC-05**: Authenticated users see a "Go to Collection" entry point from the landing page

### Catalog Enrichment

- [x] **CATL-01**: Global items have attribution fields (sourceUrl, manufacturer, imageCredit, imageSourceUrl)
- [x] **CATL-02**: Global items have a unique constraint on (brand, model) preventing duplicates
- [x] **CATL-03**: Catalog detail pages display image attribution with credit and source link
- [x] **CATL-04**: Bulk import API endpoint accepts multiple catalog items in one request
- [x] **CATL-05**: Bulk import uses upsert semantics (ON CONFLICT update, not fail)

### Agent Seeding Tools

- [x] **SEED-01**: MCP server has a dedicated `upsert_catalog_item` tool that writes to globalItems (not user-scoped)
- [x] **SEED-02**: MCP server has a `bulk_upsert_catalog` tool for batch catalog population
- [x] **SEED-03**: Catalog MCP tools include attribution fields (sourceUrl, manufacturer, imageCredit) as parameters

### Infrastructure

- [x] **INFR-01**: Public API endpoints are rate-limited to prevent abuse
- [x] **INFR-02**: Discovery feed endpoint uses cursor pagination for scalability

## Future Requirements

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

### Personalization

- **PERS-01**: Logged-in users see a feed tuned to their collection categories
- **PERS-02**: Feed algorithm recommends content based on user's hobby interests

### Reviews & Content

- **REVW-01**: Users can write structured reviews on catalog items
- **REVW-02**: Reviews appear in the discovery feed
- **REVW-03**: Curated/linked external reviews surface in feed

### SEO

- **SEO-01**: Catalog pages are crawlable by search engine bots
- **SEO-02**: Catalog pages have proper meta tags and structured data

### Catalog Seeding

- **SEED-04**: Initial seeding run populates 100+ items across key categories via agent swarm

### Reviews & Ratings (from v2.0)

- **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

### Aggregation (from v2.0)

- **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 (from v2.0)

- **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 (from v2.0)

- **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 |
|---------|--------|
| Personalized feed algorithm | Requires usage data and collection analysis — build simple feed first |
| SSR / static prerendering for SEO | Needs dedicated research on approach for TanStack Router — defer to v2.2+ |
| Freeform reviews / comments | No moderation infrastructure yet — structured UGC only |
| Admin role / permission system | Current auth model has no role distinction — API key sufficient for v2.1 |
| Image scraping automation | Legal gray area — agent seeding uses manufacturer-provided images with attribution |
| 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 |
| Price tracking / deal alerts | Requires scraping, fragile, legal gray area |
| Mobile native app | Web-first, responsive design sufficient |
