fix: remove duplicate users table definition in schema

The users table was defined twice with conflicting field orderings
(timestamp vs boolean for emailVerified, different default placements).
Kept the cleaner definition and removed the duplicate.

+# ComparAIson v0.2–v0.4 Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Replace all mock data with real API-backed pages, wire auth into the comparison flow, and add search + management features.
+
+**Architecture:** Next.js App Router API routes backed by existing Drizzle ORM schema. Server actions for simple reads, REST endpoints for complex queries. Better Auth sessions for user identity.
+
+**Tech Stack:** Next.js 15, Drizzle ORM, PostgreSQL, Better Auth, shadcn/ui, Recharts

+## Phase 1: v0.2 — Feed & Profile (Milestone #5)
+
+### Task 1.1: Create GET /api/comparisons route (#1)
+
+**Objective:** Paginated public feed API endpoint.
+
+**Files:**
+- Create: `src/app/api/comparisons/route.ts`
+
+**Step 1: Create the route file**
+
+```typescript
+// src/app/api/comparisons/route.ts
+import { db } from "@/lib/db";
+import { comparisons, comparisonItems } from "@/lib/db/schema";
+import { eq, and, ilike, desc, sql } from "drizzle-orm";

+### Task 1.3: Wire Explore page (#3)
+
+**Objective:** Replace mock data with real API calls.
+
+**Files:**
+- Modify: `src/app/(main)/explore/page.tsx`
+
+**Step 1: Replace mock data with fetch logic**
+
+Replace the entire `allComparisons` array and `categories` with:
+
+```typescript
+"use client"
+
+import { useState, useEffect, useCallback } from "react"
+// ... existing imports ...
+
+interface ExploreComparison {
+  id: string
+  title: string
+  summary: string
+  slug: string
+  tags: string[]
+  items: string[]
+  viewCount: number
+  createdAt: string
+}
+
+export default function ExplorePage() {
+  const [searchQuery, setSearchQuery] = useState("")
+  const [comparisons, setComparisons] = useState<ExploreComparison[]>([])
+  const [total, setTotal] = useState(0)
+  const [page, setPage] = useState(1)
+  const [loading, setLoading] = useState(true)
+  const [error, setError] = useState<string | null>(null)
+  const limit = 20
+
+  const fetchComparisons = useCallback(async (search: string, pageNum: number) => {
+    setLoading(true)
+    setError(null)
+    try {
+      const params = new URLSearchParams({
+        page: String(pageNum),
+        limit: String(limit),
+      })
+      if (search) params.set("search", search)
+      const res = await fetch(`/api/comparisons?${params}`)
+      if (!res.ok) throw new Error("Failed to fetch")
+      const data = await res.json()
+      if (pageNum === 1) {
+        setComparisons(data.comparisons)
+      } else {
+        setComparisons((prev) => [...prev, ...data.comparisons])
+      }
+      setTotal(data.total)
+    } catch (err) {
+      setError(err instanceof Error ? err.message : "Failed to load comparisons")
+    } finally {
+      setLoading(false)
+    }
+  }, [])
+
+  // Debounced search
+  useEffect(() => {
+    const timer = setTimeout(() => {
+      setPage(1)
+      fetchComparisons(searchQuery, 1)
+    }, 300)
+    return () => clearTimeout(timer)
+  }, [searchQuery, fetchComparisons])
+
+  // Initial load
+  useEffect(() => {
+    fetchComparisons("", 1)
+  }, [fetchComparisons])
+
+  // Extract unique tags from loaded comparisons
+  const categories = ["All", ...new Set(comparisons.flatMap((c) => c.tags))]
+  const [selectedCategory, setSelectedCategory] = useState("All")
+
+  const filtered = selectedCategory === "All"
+    ? comparisons
+    : comparisons.filter((c) => c.tags.includes(selectedCategory))
+
+  const hasMore = comparisons.length < total
+
+  // ... render (replace allComparisons references with `filtered`)
+  // Change Link href from `/compare/${comparison.id}` to `/compare/${comparison.slug}`
+}
+```
+
+**Step 2: Update "Load More" button**
+
+```tsx
+<Button 
+  variant="outline" 
+  className="gap-2"
+  onClick={() => {
+    const nextPage = page + 1
+    setPage(nextPage)
+    fetchComparisons(searchQuery, nextPage)
+  }}
+  disabled={loading || !hasMore}
+>
+  {loading ? "Loading..." : "Load More"}
+</Button>
+```

+
+### Task 1.4: Wire Profile page (#4)
+
+**Objective:** Replace mock data with real user data.
+
+**Files:**
+- Modify: `src/app/(main)/profile/page.tsx`
+
+Similar pattern to Explore — replace mock arrays with `useEffect` + `fetch` to `/api/user/comparisons` and `/api/user/stats`. Show sign-in CTA if no session.
+
+---
+
+## Phase 2: v0.3 — Auth Integration (Milestone #6)
+
+### Task 2.1: Associate comparisons with users (#5)
+
+**Objective:** Set userId on comparison creation.
+
+**Files:**
+- Modify: `src/app/api/compare/route.ts`
+- Modify: `src/app/actions/comparison.ts`
+
+Read auth session from headers, extract userId, pass to insert. Add auth check to compare page.
+
+---
+
+## Phase 3: v0.4 — Search & Polish (Milestone #7)
+
+### Task 3.1: Functional search (#6)
+
+Navigate header search to `/explore?search=...`. Read URL params in Explore page.
+
+### Task 3.2: Delete/toggle visibility (#7)
+
+Add `DELETE` and `PATCH` routes. Add dropdown menus to profile comparison cards.
+
+### Task 3.3: Loading/error states (#8)
+
+Add error rendering in compare page, error boundary, toast notifications.
