fix: include quantity in getAllItems select, createItem values, and updateItem type

Quantity was missing from three places in item.service.ts: - getAllItems didn't select it (API returned undefined) - createItem didn't pass it to insert (always used DB default of 1) - updateItem type didn't include it (silently stripped from updates) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
fix: show Add Candidate button in comparison view

+# Authentication
+
+GearBox uses a public-read, authenticated-write model. All GET endpoints are publicly accessible with no credentials required. Any request that modifies data (POST, PUT, PATCH, DELETE) requires authentication.
+
+This is a single-user app. There is exactly one admin account.
+
+## Table of Contents
+
+- [First-Time Setup](#first-time-setup)
+- [Web UI Authentication](#web-ui-authentication)
+- [API Keys](#api-keys)
+- [Auth Middleware Behavior](#auth-middleware-behavior)
+- [Auth API Reference](#auth-api-reference)
+- [Frontend Behavior](#frontend-behavior)
+
+---
+
+## First-Time Setup
+
+When no users exist, all write endpoints return `403` with `{ "error": "setup_required" }`. To create the admin account, visit `/login` in the browser and complete the setup form, or call the setup endpoint directly:
+
+```http
+POST /api/auth/setup
+Content-Type: application/json
+
+{
+  "username": "admin",
+  "password": "yourpassword"
+}
+```
+
+Requirements:
+- `username`: any non-empty string
+- `password`: minimum 6 characters
+
+This endpoint only works when no users exist. Subsequent calls return `403 { "error": "Setup already completed" }`.
+
+On success, a session cookie is set and `201` is returned:
+
+```json
+{ "username": "admin" }
+```
+
+---
+
+## Web UI Authentication
+
+Sessions use an `httpOnly` cookie named `gearbox_session`.
+
+| Property   | Value              |
+|------------|--------------------|
+| Cookie name | `gearbox_session` |
+| httpOnly   | true               |
+| sameSite   | Lax                |
+| path       | /                  |
+| Max age    | 30 days            |
+
+The session expiry is **automatically refreshed** on each authenticated request. As long as the app is used at least once every 30 days, the session stays active.
+
+Passwords are hashed with **argon2** via `Bun.password`.
+
+### Changing Your Password
+
+Requires an active session cookie.
+
+```http
+PUT /api/auth/password
+Content-Type: application/json
+
+{
+  "currentPassword": "oldpassword",
+  "newPassword": "newpassword"
+}
+```
+
+---
+
+## API Keys
+
+API keys are intended for programmatic access (scripts, MCP clients, integrations). They are managed under **Settings > API Keys** in the web UI, or via the API endpoints listed below.
+
+### Key behavior
+
+- Keys are shown **once** at creation time. Store them securely.
+- Keys are stored as an argon2 hash. Only the 8-character prefix is stored in plaintext for display and lookup purposes.
+- Pass the key via the `X-API-Key` request header on any write request.
+
+```http
+POST /api/items
+X-API-Key: gbk_a1b2c3d4...
+Content-Type: application/json
+
+{ "name": "Revelate Tangle", "categoryId": 2 }
+```
+
+If both a session cookie and an `X-API-Key` header are present, the API key is checked first.
+
+---
+
+## Auth Middleware Behavior
+
+The middleware applied to `/api/*` (excluding `/api/auth/*`) follows these rules:
+
+1. `GET` requests — always allowed, no auth check.
+2. No users exist — returns `403 { "error": "setup_required" }`.
+3. `X-API-Key` header present — verified against stored hashes; `401` on failure.
+4. `gearbox_session` cookie present — verified against sessions table; refreshed on success; `401` on failure.
+5. Neither credential present — returns `401 { "error": "Authentication required" }`.
+
+The `/api/auth/*` routes handle their own auth logic and are excluded from the global middleware.
+
+---
+
+## Auth API Reference
+
+### `GET /api/auth/me`
+
+Returns the current session state. Always public.
+
+**Response when logged in:**
+```json
+{
+  "user": { "id": 1 },
+  "setupRequired": false
+}
+```
+
+**Response when logged out, setup complete:**
+```json
+{
+  "user": null,
+  "setupRequired": false
+}
+```
+
+**Response when no users exist:**
+```json
+{
+  "user": null,
+  "setupRequired": true
+}
+```
+
+---
+
+### `POST /api/auth/setup`
+
+Create the first admin account. Only works when no users exist.
+
+**Request:**
+```json
+{
+  "username": "admin",
+  "password": "yourpassword"
+}
+```
+
+**Response:** `201`
+```json
+{ "username": "admin" }
+```
+
+Sets `gearbox_session` cookie.
+
+---
+
+### `POST /api/auth/login`
+
+Log in with username and password.
+
+**Request:**
+```json
+{
+  "username": "admin",
+  "password": "yourpassword"
+}
+```
+
+**Response:** `200`
+```json
+{ "username": "admin" }
+```
+
+Sets `gearbox_session` cookie. Returns `401` on invalid credentials.
+
+---
+
+### `POST /api/auth/logout`
+
+Clear the current session. No request body needed.
+
+**Response:**
+```json
+{ "ok": true }
+```
+
+Clears the `gearbox_session` cookie and deletes the session from the database.
+
+---
+
+### `PUT /api/auth/password`
+
+Change the admin password. Requires an active session cookie (not API key).
+
+**Request:**
+```json
+{
+  "currentPassword": "oldpassword",
+  "newPassword": "newpassword"
+}
+```
+
+**Response:**
+```json
+{ "ok": true }
+```
+
+Returns `401` if `currentPassword` is incorrect.
+
+---
+
+### `GET /api/auth/keys`
+
+List all API keys. Returns name, prefix, and creation timestamp — never the full key.
+
+Requires auth.
+
+**Response:**
+```json
+[
+  {
+    "id": 1,
+    "name": "Claude Code",
+    "prefix": "gbk_a1b2",
+    "createdAt": "2025-03-01T10:00:00.000Z"
+  }
+]
+```
+
+---
+
+### `POST /api/auth/keys`
+
+Create a new API key. The full key is returned **once** and cannot be retrieved again.
+
+Requires auth.
+
+**Request:**
+```json
+{ "name": "Claude Code" }
+```
+
+**Response:** `201`
+```json
+{
+  "id": 1,
+  "name": "Claude Code",
+  "key": "gbk_a1b2c3d4e5f6g7h8i9j0...",
+  "prefix": "gbk_a1b2"
+}
+```
+
+---
+
+### `DELETE /api/auth/keys/:id`
+
+Revoke an API key by ID. Requires auth.
+
+**Response:**
+```json
+{ "ok": true }
+```
+
+---
+
+## Frontend Behavior
+
+- A login button is shown in the top-right corner of the UI (Gitea-style).
+- The floating action button (FAB) for adding items is hidden when not logged in.
+- Edit and delete actions on items, threads, and setups require auth. Unauthenticated users see read-only views.
+- When `setupRequired` is true, the UI redirects to the setup flow.

+# MCP Server
+
+GearBox includes a built-in MCP (Model Context Protocol) server that exposes your gear collection to AI assistants. It runs inside the Hono process — no separate service is needed.
+
+The MCP server implements the [Streamable HTTP transport](https://modelcontextprotocol.io/specification) from `@modelcontextprotocol/sdk` and is mounted at `/mcp`.

+
+## Enabling and Disabling
+
+The MCP server is **enabled by default**. To disable it, set the environment variable:
+
+```bash
+GEARBOX_MCP=false bun run dev:server
+```
+
+Or in your environment file:
+
+```bash
+GEARBOX_MCP=false
+```
+
+When disabled, the `/mcp` route is not registered and any requests to it return 404.
+
+---
+
+## Authentication
+
+The MCP server requires an API key when the app has been set up (i.e., at least one user exists). Pass the key via the `X-API-Key` header in your MCP client configuration.
+
+To create an API key:
+1. Log in to the web UI.
+2. Go to **Settings > API Keys**.
+3. Click **New Key**, give it a name, and copy the full key shown.
+
+The full key is only shown once. Store it in your client configuration immediately.
+
+See [authentication.md](authentication.md) for full API key documentation.

+## Connecting an AI Client
+
+### Claude Code
+
+Add the MCP server to `.claude/settings.json` in your project or globally at `~/.claude/settings.json`:
+
+```json
+{
+  "mcpServers": {
+    "gearbox": {
+      "type": "streamable-http",
+      "url": "http://localhost:3000/mcp",
+      "headers": {
+        "X-API-Key": "your-api-key-here"
+      }
+    }
+  }
+}
+```
+
+### Claude Desktop
+
+Add the server to `claude_desktop_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "gearbox": {
+      "type": "streamable-http",
+      "url": "http://localhost:3000/mcp",
+      "headers": {
+        "X-API-Key": "your-api-key-here"
+      }
+    }
+  }
+}
+```
+
+On macOS, the config file is at `~/Library/Application Support/Claude/claude_desktop_config.json`.
+
+After updating the config, restart Claude Desktop (or reload the window in Claude Code) for the server to connect.
+
+---
+
+## Tools
+
+The MCP server exposes 18 tools across five categories.
+
+### Items
+
+| Tool           | Description                                                                                                |
+|----------------|------------------------------------------------------------------------------------------------------------|
+| `list_items`   | List all items in the gear collection, optionally filtered by `categoryId`.                               |
+| `get_item`     | Get a single item by ID with all details.                                                                  |

+
+### Candidates
+
+| Tool               | Description                                                           |

+
+| Tool            | Description                                                                                           |
+|-----------------|-------------------------------------------------------------------------------------------------------|
+| `list_setups`   | List all gear setups with item counts and weight/cost totals.                                        |
+| `get_setup`     | Get a setup with all its items and details.                                                          |
+| `create_setup`  | Create a new gear setup (e.g., "Bikepacking weekend").                                              |

+|-------------------------|--------------------------------------------------------------------------------------------------|
+| `upload_image_from_url` | Fetch an image from a URL and save it locally. Returns a `filename` to use with items or candidates. |
+
+---
+
+## Resources
+
+### `gearbox://collection/summary`
+
+Returns a JSON overview of the entire gear collection, including:
+- Total item count, weight, and cost
+- Per-category breakdowns
+- Active research thread count
+
+Read this resource first to orient yourself before running queries or making changes.
+
+---
+
+## Recommended Workflow
+
+Tool descriptions are written to guide AI assistants toward the research thread workflow rather than creating items directly. The intended flow for evaluating a new piece of gear is:
+
+1. **`create_thread`** — open a research thread for the gear slot (e.g., "Handlebar bag")
+2. **`add_candidate`** — add options with prices, weights, pros, and cons
+3. **`get_thread`** — review all candidates side by side
+4. **`resolve_thread`** — pick the winner; it becomes a new item in the collection automatically
+
+Use `create_item` directly only when you already know exactly what you're adding and no research is needed.
+
+---
+
+## Example Session
+
+The following illustrates a typical assistant interaction via the MCP server.
+
+**User:** "I need a new handlebar bag. Can you research some options and add them?"
+
+**Assistant actions:**
+
+```
+1. list_categories
+   -> finds "Bags" category (id: 2)
+
+2. create_thread { name: "Handlebar bag", categoryId: 2 }
+   -> thread id: 7
+
+3. upload_image_from_url { url: "https://revelatedesigns.com/sweetroll.jpg" }
+   -> filename: "1710000000000-uuid.jpg"
+
+4. add_candidate {
+     threadId: 7,
+     name: "Revelate Sweetroll",
+     categoryId: 2,
+     weightGrams: 290,
+     priceCents: 13500,
+     productUrl: "https://revelatedesigns.com/...",
+     imageFilename: "1710000000000-uuid.jpg",
+     pros: "Waterproof, 16L, fits most drop bars",
+     cons: "Expensive, bulky profile"
+   }
+
+5. add_candidate {
+     threadId: 7,
+     name: "Apidura Backcountry Handlebar Pack",
+     categoryId: 2,
+     weightGrams: 230,
+     priceCents: 11000,
+     pros: "Lighter, packable, good attachment system",
+     cons: "Smaller capacity"
+   }
+
+6. add_candidate { ... }
+
+7. get_thread { id: 7 }
+   -> presents comparison to user
+
+8. resolve_thread { threadId: 7, candidateId: 14 }
+   -> Revelate Sweetroll added to collection as item id: 42
+```
+
+---
+
+## Implementation Structure
+
+The MCP server source lives under `src/server/mcp/`:
+
+```
+src/server/mcp/
+  index.ts              # Server factory, transport handling, auth middleware, Hono route registration
+  tools/
+    items.ts            # list_items, get_item, create_item, update_item, delete_item
+    categories.ts       # list_categories, create_category
+    threads.ts          # list_threads, get_thread, create_thread, resolve_thread,
+                        # add_candidate, update_candidate, remove_candidate
+    setups.ts           # list_setups, get_setup, create_setup, update_setup
+    images.ts           # upload_image_from_url
+  resources/
+    collection.ts       # gearbox://collection/summary resource handler
+```
+
+Each tool file exports a `*ToolDefinitions` array (name, description, inputSchema) and a `register*Tools(db)` factory function that returns handler implementations. The server in `index.ts` iterates over definitions and registers each handler with the MCP `McpServer` instance.
+
+Session management uses the `WebStandardStreamableHTTPServerTransport` with UUID-based session IDs tracked in an in-memory `Map`. Sessions are cleaned up when the transport closes.

+# Codebase Improvements Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Harden the server (explicit DB context, param validation, error handling, rate limiting), add client error boundaries, split the oversized collection route into focused components, and fix stale docs.
+
+**Architecture:** Server changes are middleware-level (DB context, error handler, rate limiter) plus a small utility for param parsing. Client changes are a TanStack Router error boundary on the root route and extracting three tab components from the 634-line collection route. Docs change is a one-line fix in PROJECT.md.
+
+**Tech Stack:** Hono middleware, TanStack Router errorComponent, React, TypeScript
+
+---
+
+### Task 1: Explicit DB Context Middleware
+
+**Files:**
+- Modify: `src/server/index.ts:1-59`
+- Modify: `src/server/routes/settings.ts:3,12` (remove prodDb fallback)
+
+- [ ] **Step 1: Add DB import and middleware to server index**
+
+In `src/server/index.ts`, add the import for the production database at the top, alongside existing imports:
+
+```ts
+import { db as prodDb } from "../db/index.ts";
+```
+
+Then add a middleware **before** the auth middleware (before line 26) that sets the DB on every API request:
+
+```ts
+// Inject production database into request context
+app.use("/api/*", async (c, next) => {
+	c.set("db", prodDb);
+	return next();
+});
+```
+
+- [ ] **Step 2: Fix auth middleware comment**
+
+In the same file, update the comment on the auth middleware from:
+
+```ts
+// Auth middleware for write operations (POST/PUT/DELETE) on non-auth routes
+```
+
+to:
+
+```ts
+// Auth middleware for write operations (POST/PUT/PATCH/DELETE) on non-auth routes
+```
+
+- [ ] **Step 3: Remove prodDb fallback from settings route**
+
+In `src/server/routes/settings.ts`, remove the `prodDb` import and fallback. Change:
+
+```ts
+import { db as prodDb } from "../../db/index.ts";
+```
+
+Remove this import entirely.
+
+Change both occurrences of:
+```ts
+const database = c.get("db") ?? prodDb;
+```
+to:
+```ts
+const database = c.get("db");
+```
+
+- [ ] **Step 4: Run tests**
+
+Run: `bun test`
+Expected: All 183 tests pass. Tests already set `c.set("db", testDb)` so this change doesn't affect them.
+
+- [ ] **Step 5: Run lint**
+
+Run: `bun run lint`
+Expected: No errors.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/server/index.ts src/server/routes/settings.ts
+git commit -m "fix: add explicit DB context middleware for all API routes"
+```
+
+---
+
+### Task 2: Route Parameter Validation
+
+**Files:**
+- Create: `src/server/lib/params.ts`
+- Modify: `src/server/routes/items.ts`
+- Modify: `src/server/routes/categories.ts`
+- Modify: `src/server/routes/threads.ts`
+- Modify: `src/server/routes/setups.ts`
+- Modify: `src/server/routes/auth.ts:187-189`
+
+- [ ] **Step 1: Create parseId helper**
+
+Create `src/server/lib/params.ts`:
+
+```ts
+/**
+ * Parse a route parameter as a positive integer ID.
+ * Returns the number if valid, or null if the string is not a positive integer.
+ */
+export function parseId(raw: string): number | null {
+	const id = Number(raw);
+	if (!Number.isInteger(id) || id <= 0) return null;
+	return id;
+}
+```
+
+- [ ] **Step 2: Update items routes**
+
+In `src/server/routes/items.ts`, add the import:
+
+```ts
+import { parseId } from "../lib/params.ts";
+```
+
+Replace all `Number(c.req.param("id"))` patterns. For each route that uses an ID param, add validation. Example for `GET /:id`:
+
+```ts
+app.get("/:id", (c) => {
+	const db = c.get("db");
+	const id = parseId(c.req.param("id"));
+	if (!id) return c.json({ error: "Invalid item ID" }, 400);
+	const item = getItemById(db, id);
+	if (!item) return c.json({ error: "Item not found" }, 404);
+	return c.json(item);
+});
+```
+
+Apply the same pattern to `PUT /:id` and `DELETE /:id`. In each case, add `const id = parseId(...)` + the null check returning 400 right after.
+
+- [ ] **Step 3: Update categories routes**
+
+In `src/server/routes/categories.ts`, add the import:
+
+```ts
+import { parseId } from "../lib/params.ts";
+```
+
+Replace `Number(c.req.param("id"))` with `parseId(c.req.param("id"))` in `PUT /:id` and `DELETE /:id`, adding the null check:
+
+```ts
+const id = parseId(c.req.param("id"));
+if (!id) return c.json({ error: "Invalid category ID" }, 400);
+```
+
+- [ ] **Step 4: Update threads routes**
+
+In `src/server/routes/threads.ts`, add the import:
+
+```ts
+import { parseId } from "../lib/params.ts";
+```
+
+Replace all `Number(c.req.param(...))` calls. There are 8 occurrences across these handlers:
+- `GET /:id` — `const id = parseId(c.req.param("id"))`
+- `PUT /:id` — same
+- `DELETE /:id` — same
+- `POST /:id/candidates` — `const threadId = parseId(c.req.param("id"))`
+- `PUT /:threadId/candidates/:candidateId` — `const candidateId = parseId(c.req.param("candidateId"))`
+- `DELETE /:threadId/candidates/:candidateId` — same
+- `PATCH /:id/candidates/reorder` — `const threadId = parseId(c.req.param("id"))`
+- `POST /:id/resolve` — `const threadId = parseId(c.req.param("id"))`
+
+For each, add the null check returning 400 with a descriptive message like `"Invalid thread ID"` or `"Invalid candidate ID"`.
+
+- [ ] **Step 5: Update setups routes**
+
+In `src/server/routes/setups.ts`, add the import:
+
+```ts
+import { parseId } from "../lib/params.ts";
+```
+
+Replace all `Number(c.req.param(...))` calls. There are 6 occurrences:
+- `GET /:id` — `const id = parseId(c.req.param("id"))`
+- `PUT /:id` — same
+- `DELETE /:id` — same
+- `PUT /:id/items` — same
+- `PATCH /:id/items/:itemId/classification` — both `setupId` and `itemId`
+- `DELETE /:id/items/:itemId` — both `setupId` and `itemId`
+
+For the classification and item removal routes with two params:
+
+```ts
+const setupId = parseId(c.req.param("id"));
+const itemId = parseId(c.req.param("itemId"));
+if (!setupId || !itemId) return c.json({ error: "Invalid ID" }, 400);
+```
+
+- [ ] **Step 6: Update auth routes**
+
+In `src/server/routes/auth.ts`, add the import:
+
+```ts
+import { parseId } from "../lib/params.ts";
+```
+
+Update `DELETE /keys/:id` (line 187-189):
+
+```ts
+app.delete("/keys/:id", requireAuth, (c) => {
+	const db = c.get("db");
+	const id = parseId(c.req.param("id"));
+	if (!id) return c.json({ error: "Invalid key ID" }, 400);
+	deleteApiKey(db, id);
+	return c.json({ ok: true });
+});
+```
+
+- [ ] **Step 7: Run tests**
+
+Run: `bun test`
+Expected: All 183 tests pass. Existing tests use valid integer IDs so no breakage.
+
+- [ ] **Step 8: Run lint**
+
+Run: `bun run lint`
+Expected: No errors.
+
+- [ ] **Step 9: Commit**
+
+```bash
+git add src/server/lib/params.ts src/server/routes/items.ts src/server/routes/categories.ts src/server/routes/threads.ts src/server/routes/setups.ts src/server/routes/auth.ts
+git commit -m "fix: validate route ID parameters, return 400 for invalid IDs"
+```
+
+---
+
+### Task 3: Centralized Error Handler
+
+**Files:**
+- Modify: `src/server/index.ts`
+
+- [ ] **Step 1: Add onError handler**
+
+In `src/server/index.ts`, add the error handler after the app is created (after `const app = new Hono()`) but before any routes:
+
+```ts
+// Centralized error handler
+app.onError((err, c) => {
+	console.error(`[${c.req.method}] ${c.req.path}:`, err);
+	const message =
+		process.env.NODE_ENV === "production"
+			? "Internal server error"
+			: err.message || "Internal server error";
+	return c.json({ error: message }, 500);
+});
+```
+
+- [ ] **Step 2: Run tests**
+
+Run: `bun test`
+Expected: All 183 tests pass.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/server/index.ts
+git commit -m "fix: add centralized error handler for unhandled exceptions"
+```
+
+---
+
+### Task 4: Rate Limiting on Auth Endpoints
+
+**Files:**
+- Create: `src/server/middleware/rateLimit.ts`
+- Modify: `src/server/routes/auth.ts`
+
+- [ ] **Step 1: Create rate limiter middleware**
+
+Create `src/server/middleware/rateLimit.ts`:
+
+```ts
+import type { Context, Next } from "hono";
+
+interface RateLimitEntry {
+	count: number;
+	resetAt: number;
+}
+
+const store = new Map<string, RateLimitEntry>();
+
+const MAX_ATTEMPTS = 5;
+const WINDOW_MS = 15 * 60 * 1000; // 15 minutes
+
+function getClientIp(c: Context): string {
+	return c.req.header("x-forwarded-for")?.split(",")[0]?.trim() || "unknown";
+}
+
+function cleanup() {
+	const now = Date.now();
+	for (const [key, entry] of store) {
+		if (now >= entry.resetAt) {
+			store.delete(key);
+		}
+	}
+}
+
+export async function rateLimit(c: Context, next: Next) {
+	cleanup();
+
+	const ip = getClientIp(c);
+	const key = `${ip}:${c.req.path}`;
+	const now = Date.now();
+
+	const entry = store.get(key);
+
+	if (!entry || now >= entry.resetAt) {
+		store.set(key, { count: 1, resetAt: now + WINDOW_MS });
+		return next();
+	}
+
+	if (entry.count >= MAX_ATTEMPTS) {
+		const retryAfter = Math.ceil((entry.resetAt - now) / 1000);
+		c.header("Retry-After", String(retryAfter));
+		return c.json({ error: "Too many attempts. Try again later." }, 429);
+	}
+
+	entry.count++;
+	return next();
+}
+```
+
+- [ ] **Step 2: Apply rate limiter to auth routes**
+
+In `src/server/routes/auth.ts`, add the import:
+
+```ts
+import { rateLimit } from "../middleware/rateLimit.ts";
+```
+
+Update the `POST /setup` handler to include the rate limiter:
+
+```ts
+app.post("/setup", rateLimit, zValidator("json", setupSchema), async (c) => {
+```
+
+Update the `POST /login` handler to include the rate limiter:
+
+```ts
+app.post("/login", rateLimit, zValidator("json", loginSchema), async (c) => {
+```
+
+- [ ] **Step 3: Run tests**
+
+Run: `bun test`
+Expected: All 183 tests pass. Auth tests make fewer than 5 requests per endpoint so rate limiting won't trigger.
+
+- [ ] **Step 4: Run lint**
+
+Run: `bun run lint`
+Expected: No errors.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/server/middleware/rateLimit.ts src/server/routes/auth.ts
+git commit -m "feat: add rate limiting on login and setup endpoints"
+```
+
+---
+
+### Task 5: Client Error Boundary
+
+**Files:**
+- Modify: `src/client/routes/__root.tsx`
+
+- [ ] **Step 1: Add error boundary component and wire it up**
+
+In `src/client/routes/__root.tsx`, add the import for `useRouter` at the top (add to existing import from `@tanstack/react-router`):
+
+```ts
+import {
+	createRootRoute,
+	Outlet,
+	useMatchRoute,
+	useNavigate,
+	useRouter,
+	type ErrorComponentProps,
+} from "@tanstack/react-router";
+```
+
+Add the `errorComponent` to the route definition:
+
+```ts
+export const Route = createRootRoute({
+	component: RootLayout,
+	errorComponent: RootErrorBoundary,
+});
+```
+
+Add the `RootErrorBoundary` function before `RootLayout`:
+
+```tsx
+function RootErrorBoundary({ error, reset }: ErrorComponentProps) {
+	const router = useRouter();
+
+	return (
+		<div className="min-h-screen bg-gray-50 flex items-center justify-center">
+			<div className="max-w-md mx-auto text-center px-4">
+				<div className="w-12 h-12 bg-red-100 rounded-full flex items-center justify-center mx-auto mb-4">
+					<svg
+						className="w-6 h-6 text-red-600"
+						fill="none"
+						stroke="currentColor"
+						viewBox="0 0 24 24"
+					>
+						<path
+							strokeLinecap="round"

+### Task 6: Split Collection Route into Tab Components
+
+**Files:**
+- Create: `src/client/components/CollectionView.tsx`
+- Create: `src/client/components/PlanningView.tsx`
+- Create: `src/client/components/SetupsView.tsx`
+- Modify: `src/client/routes/collection/index.tsx`
+
+- [ ] **Step 1: Create CollectionView component**
+
+Create `src/client/components/CollectionView.tsx` with the `CollectionView` function extracted from `collection/index.tsx` (lines 72-334). The component needs these imports:
+
+```tsx
+import { useMemo, useState } from "react";
+import { CategoryFilterDropdown } from "./CategoryFilterDropdown";
+import { CategoryHeader } from "./CategoryHeader";
+import { ItemCard } from "./ItemCard";
+import { useCategories } from "../hooks/useCategories";
+import { useCurrency } from "../hooks/useCurrency";
+import { useItems } from "../hooks/useItems";
+import { useTotals } from "../hooks/useTotals";
+import { useWeightUnit } from "../hooks/useWeightUnit";
+import { formatPrice, formatWeight } from "../lib/formatters";
+import { LucideIcon } from "../lib/iconData";
+import { useUIStore } from "../stores/uiStore";
+
+export function CollectionView() {
+	// ... exact same function body as lines 73-334 of collection/index.tsx
+}
+```
+
+Copy the entire `CollectionView` function body as-is. No logic changes.
+
+- [ ] **Step 2: Create PlanningView component**
+
+Create `src/client/components/PlanningView.tsx` with the `PlanningView` function extracted from `collection/index.tsx` (lines 337-523):
+
+```tsx
+import { useState } from "react";
+import { CategoryFilterDropdown } from "./CategoryFilterDropdown";
+import { CreateThreadModal } from "./CreateThreadModal";
+import { ThreadCard } from "./ThreadCard";
+import { useCategories } from "../hooks/useCategories";
+import { useThreads } from "../hooks/useThreads";
+import { useUIStore } from "../stores/uiStore";
+
+export function PlanningView() {
+	// ... exact same function body as lines 338-523 of collection/index.tsx
+}
+```
+
+Copy the entire `PlanningView` function body as-is. No logic changes.
+
+- [ ] **Step 3: Create SetupsView component**
+
+Create `src/client/components/SetupsView.tsx` with the `SetupsView` function extracted from `collection/index.tsx` (lines 526-633):
+
+```tsx
+import { useState } from "react";
+import { SetupCard } from "./SetupCard";
+import { useCreateSetup, useSetups } from "../hooks/useSetups";
+
+export function SetupsView() {
+	// ... exact same function body as lines 527-633 of collection/index.tsx
+}
+```
+
+Copy the entire `SetupsView` function body as-is. No logic changes.
+
+- [ ] **Step 4: Update collection/index.tsx**
+
+Replace the entire file content. Keep only the route definition, tab switching logic, animation constants, and imports from the new components:
+
+```tsx
+import { createFileRoute } from "@tanstack/react-router";
+import { AnimatePresence, motion } from "framer-motion";
+import { useRef } from "react";
+import { z } from "zod";
+import { CollectionView } from "../../components/CollectionView";
+import { PlanningView } from "../../components/PlanningView";
+import { SetupsView } from "../../components/SetupsView";
+
+const searchSchema = z.object({
+	tab: z.enum(["gear", "planning", "setups"]).catch("gear"),
+});
+
+export const Route = createFileRoute("/collection/")({
+	validateSearch: searchSchema,
+	component: CollectionPage,
+});
+
+const TAB_ORDER = ["gear", "planning", "setups"] as const;
+
+const slideVariants = {
+	enter: (dir: number) => ({ x: `${dir * 15}%`, opacity: 0 }),
+	center: { x: 0, opacity: 1 },
+	exit: (dir: number) => ({ x: `${dir * -15}%`, opacity: 0 }),
+};
+
+function CollectionPage() {
+	const { tab } = Route.useSearch();
+	const prevTab = useRef(tab);
+
+	const direction =
+		TAB_ORDER.indexOf(tab) >= TAB_ORDER.indexOf(prevTab.current) ? 1 : -1;
+	prevTab.current = tab;
+
+	return (
+		<div className="max-w-7xl mx-auto px-4 sm:px-6 lg:px-8 py-6 overflow-x-hidden">
+			<AnimatePresence mode="wait" initial={false} custom={direction}>
+				<motion.div
+					key={tab}
+					custom={direction}
+					variants={slideVariants}
+					initial="enter"
+					animate="center"
+					exit="exit"
+					transition={{ duration: 0.12, ease: "easeInOut" }}
+				>
+					{tab === "gear" ? (
+						<CollectionView />
+					) : tab === "planning" ? (
+						<PlanningView />
+					) : (
+						<SetupsView />
+					)}
+				</motion.div>
+			</AnimatePresence>
+		</div>
+	);
+}
+```
+

+### Task 7: Docs Cleanup
+
+**Files:**
+- Modify: `.planning/PROJECT.md:84`
+
+- [ ] **Step 1: Update stale constraint**
+
+In `.planning/PROJECT.md`, change line 84 from:

+```
+- **Scope**: No auth, single user for v1
+```
+
+to:
+
+```
+- **Scope**: Single user with cookie/API key auth

+# Testing Improvements Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add unit tests for new server code (parseId, rate limiter, param validation routes), set up Playwright E2E testing with a seeded database, and write E2E tests covering dashboard, collection, threads, auth, and error handling.
+
+**Architecture:** Unit tests use existing Bun test runner + Hono `app.request()` pattern. E2E tests use Playwright against a real server with a pre-seeded SQLite database. A global-setup script creates the test DB using Drizzle migrations + direct inserts before Playwright runs.
+
+**Tech Stack:** Bun test runner, Playwright (Chromium only), Drizzle ORM migrations, Hono

+# Code Quality Improvements (Round 2) Design
+
+**Date:** 2026-04-03
+**Scope:** Combined formatters hook, test helper schema generation, stale todo cleanup
+
+## 1. useFormatters Combined Hook
+
+**Problem:** 14 component files import the same 3-4 lines: `useWeightUnit`, `useCurrency`, `formatWeight`, `formatPrice`. This is repetitive boilerplate.
+
+**Solution:** Create `src/client/hooks/useFormatters.ts` that returns pre-bound formatting functions:
+
+```ts
+export function useFormatters() {
+  const unit = useWeightUnit();
+  const currency = useCurrency();
+  return {
+    weight: (grams: number | null) => formatWeight(grams, unit),
+    price: (cents: number | null) => formatPrice(cents, currency),
+    unit,
+    currency,
+  };
+}
+```
+
+**Consumer files to update (14):**
+- CollectionView.tsx
+- setups/$setupId.tsx
+- routes/index.tsx
+- WeightSummaryCard.tsx
+- TotalsBar.tsx
+- settings.tsx
+- ThreadCard.tsx
+- SetupCard.tsx
+- ItemPicker.tsx
+- ItemCard.tsx
+- ComparisonTable.tsx
+- CandidateCard.tsx
+- CandidateListItem.tsx
+- CategoryHeader.tsx
+
+Each file replaces 3-4 imports + 2 hook calls with 1 import + 1 destructured hook call. Components that need raw `unit` or `currency` (e.g., WeightSummaryCard uses `unit` as a type, TotalsBar has a unit toggle) get them from the return object.
+
+## 2. Test Helper Schema Generation
+
+**Problem:** `tests/helpers/db.ts` has 120 lines of hand-written CREATE TABLE SQL that must manually mirror `src/db/schema.ts`. Any schema change requires updating both files — a known source of `SqliteError: no such column` failures.
+
+**Solution:** Replace hand-written SQL with Drizzle's migration runner:
+
+```ts
+import { migrate } from "drizzle-orm/bun-sqlite/migrator";
+
+export function createTestDb() {
+  const sqlite = new Database(":memory:");
+  sqlite.run("PRAGMA foreign_keys = ON");
+  const db = drizzle(sqlite, { schema });
+  migrate(db, { migrationsFolder: "./drizzle" });
+  db.insert(schema.categories).values({ name: "Uncategorized", icon: "package" }).run();
+  return db;
+}
+```
+
+This reduces the file from ~128 lines to ~15 lines and eliminates all future manual sync.
+
+## 3. Stale Todo Cleanup
+
+**Problem:** Pending todo "Replace planning category filter select with icon-aware dropdown" from 2026-03-15 is already resolved — `PlanningView.tsx` uses `<CategoryFilterDropdown>` which renders Lucide icons.
+
+**Solution:** Move the todo file from `pending/` to `done/`.
+
+## Commit Strategy
+
+1. **useFormatters hook** — create hook + update all 14 consumer files
+2. **Test helper migration** — replace hand-written SQL with migrate()
+3. **Todo cleanup** — move stale todo to done

+# Codebase Improvements Design
+
+**Date:** 2026-04--03
+**Scope:** General code quality, error handling, resilience, and maintainability improvements
+
+## 1. Server Hardening
+
+### 1a. Explicit DB Context Middleware
+
+**File:** `src/server/index.ts`
+
+Add middleware that explicitly sets `c.set("db", prodDb)` for all API routes. Currently routes call `c.get("db")` but nothing sets it in production — services silently fall back to `prodDb` via default parameters. This makes production behavior match the test pattern.
+
+```ts
+import { db as prodDb } from "../db/index.ts";
+
+app.use("/api/*", async (c, next) => {
+  c.set("db", prodDb);
+  return next();
+});
+```
+
+Place this **before** the auth middleware so `db` is available when auth checks run.
+
+### 1b. Route Parameter Validation
+
+**New file:** `src/server/lib/params.ts`
+
+Create a helper that validates numeric route params:
+
+```ts
+export function parseId(raw: string): number | null {
+  const id = Number(raw);
+  if (!Number.isInteger(id) || id <= 0) return null;
+  return id;
+}
+```
+
+Update all route files (`items.ts`, `threads.ts`, `categories.ts`, `setups.ts`) to replace `Number(c.req.param("id"))` with `parseId()`, returning 400 for invalid IDs.
+
+### 1c. Centralized Error Handling
+
+**File:** `src/server/index.ts`
+
+Add Hono's `onError` handler:
+
+```ts
+app.onError((err, c) => {
+  console.error(`[${c.req.method}] ${c.req.path}:`, err);
+  const status = err instanceof HTTPException ? err.status : 500;
+  const message = process.env.NODE_ENV === "production"
+    ? "Internal server error"
+    : err.message;
+  return c.json({ error: message }, status);
+});
+```
+
+### 1d. Auth Comment Fix
+
+**File:** `src/server/index.ts`
+
+Change comment from:
+```
+// Auth middleware for write operations (POST/PUT/DELETE) on non-auth routes
+```
+To:
+```
+// Auth middleware for write operations (POST/PUT/PATCH/DELETE) on non-auth routes
+```
+
+### 1e. Rate Limiting on Auth Endpoints
+
+**New file:** `src/server/middleware/rateLimit.ts`
+
+In-memory rate limiter using a `Map<string, { count: number; resetAt: number }>`:
+
+- Tracks by IP (`c.req.header("x-forwarded-for") || "unknown"`)
+- 5 attempts per 15-minute window
+- Returns 429 with `{ error: "Too many attempts. Try again later." }` and `Retry-After` header
+- Stale entries cleaned on each check
+- Applied to `POST /api/auth/login` and `POST /api/auth/setup`
+
+## 2. Client Resilience
+
+### Error Boundary
+
+**File:** `src/client/routes/__root.tsx`
+
+Add `errorComponent` to the root route definition:
+
+```ts
+export const Route = createRootRoute({
+  component: RootLayout,
+  errorComponent: RootErrorBoundary,
+});
+```
+
+`RootErrorBoundary` renders a centered error message with:
+- "Something went wrong" heading
+- Error message in dev mode
+- "Try again" button that calls `router.invalidate()` + `reset()`
+
+Uses TanStack Router's `ErrorComponentProps` which provides `error` and `reset`.
+
+## 3. Client Refactor
+
+### Split collection/index.tsx
+
+Extract the three tab-level functions into separate component files:
+
+| Source function | New file | Approx lines |
+|----------------|----------|-------------|
+| `CollectionView()` | `src/client/components/CollectionView.tsx` | ~260 |
+| `PlanningView()` | `src/client/components/PlanningView.tsx` | ~190 |
+| `SetupsView()` | `src/client/components/SetupsView.tsx` | ~110 |
+
+`collection/index.tsx` keeps:
+- Route definition with `searchSchema` and `validateSearch`
+- `CollectionPage` function (tab switcher + AnimatePresence)
+- `TAB_ORDER` and `slideVariants` constants
+- Imports from the three new component files
+
+Each extracted component is a named export, self-contained with its own hooks and local state.
+
+## 4. Docs Cleanup
+
+### PROJECT.md
+
+**File:** `.planning/PROJECT.md`
+
+Update Constraints section line:
+```
+- **Scope**: No auth, single user for v1
+```
+To:
+```
+- **Scope**: Single user with cookie/API key auth
+```
+
+## Commit Strategy
+
+Group into 3-4 commits by area:
+1. **Server hardening**: DB middleware, param validation, error handler, rate limiter, comment fix
+2. **Client resilience + refactor**: Error boundary, split collection route
+3. **Docs cleanup**: PROJECT.md update
+
+## Testing
+
+- All 183 existing tests must continue to pass
+- Rate limiter: manual verification (no automated test needed for in-memory rate limiting in a single-user app)
+- Error boundary: manual verification by triggering a render error
+- Param validation: existing route tests cover happy paths; invalid IDs are a new edge case but won't break existing tests

+# Testing Improvements Design
+
+**Date:** 2026-04-03
+**Scope:** Unit tests for new server code + Playwright E2E test setup with seeded database
+
+## Part 1: Unit/Integration Tests (Bun test runner)
+
+### tests/lib/params.test.ts
+
+Tests for `parseId` helper in `src/server/lib/params.ts`:
+- Valid positive integers (1, 42, 999) return the number
+- Zero returns null
+- Negative numbers (-1, -100) return null
+- Decimals (1.5, 3.14) return null
+- Non-numeric strings ("abc", "", "hello") return null
+- NaN-producing values return null
+
+### tests/middleware/rateLimit.test.ts
+
+Tests for rate limiter in `src/server/middleware/rateLimit.ts`:
+- First request passes through (200)
+- 5 requests succeed, 6th returns 429
+- 429 response includes `Retry-After` header
+- Different IPs tracked independently
+- After window expires, requests succeed again
+
+Since the rate limiter uses a module-level `Map`, tests need to either:
+- Reset the store between tests (export a `resetStore` for testing), OR
+- Use unique paths/IPs per test to avoid interference
+
+Recommended: export a `_resetForTesting()` function from rateLimit.ts that clears the store. Only used in tests.
+
+### tests/routes/params.test.ts
+
+Route-level integration tests verifying 400 responses for invalid IDs:
+- `GET /api/items/abc` → 400
+- `GET /api/items/-1` → 400
+- `GET /api/items/0` → 400
+- `DELETE /api/categories/notanumber` → 400
+- `GET /api/threads/abc` → 400
+- `GET /api/setups/abc` → 400
+
+Uses existing test app pattern with in-memory DB.
+
+## Part 2: Playwright E2E Setup
+
+### Installation
+
+- `bun add -d @playwright/test`
+- `bunx playwright install chromium` (only Chromium needed)
+
+### Configuration: playwright.config.ts
+
+```ts
+export default defineConfig({
+  testDir: "./e2e",
+  webServer: {
+    command: "DATABASE_PATH=./e2e/test.db bun run dev:server",
+    port: 3000,
+    reuseExistingServer: !process.env.CI,
+  },
+  use: {
+    baseURL: "http://localhost:3000",
+  },
+  projects: [{ name: "chromium", use: { ...devices["Desktop Chrome"] } }],
+});
+```
+
+### Database Seeding: e2e/seed.ts
+
+Script that creates `e2e/test.db` with:
+- Run Drizzle migrations against the file
+- Seed data:
+  - 1 user (username: "admin", password: "password123")
+  - 3 categories: Shelter, Sleep System, Cook Kit
+  - 6 items across categories with realistic weights/prices
+  - 1 active thread with 3 candidates (with pros/cons, sort_order)
+  - 1 resolved thread
+  - 1 setup with 4 items (mixed classifications)
+  - Settings: weightUnit=g, currency=USD, onboardingComplete=true

+# v1.4 Collection Tools Design
+
+**Date:** 2026-04-03
+**Milestone:** v1.4 Collection Tools
+**Scope:** Setup impact preview, item quantity, CSV import/export, item duplication
+
+## Feature 1: Setup Impact Preview
+
+Already fully designed in `.planning/phases/13-setup-impact-preview/`. Two plans exist:
+- **13-01**: Pure `computeImpactDeltas` function + `useImpactDeltas` hook + uiStore state (TDD)
+- **13-02**: `SetupImpactSelector` + `ImpactDeltaBadge` components wired into thread detail
+
+Execute the existing plans as-is. No design changes needed.
+
+## Feature 2: Item Quantity
+
+### Schema
+
+Add `quantity INTEGER NOT NULL DEFAULT 1` to `items` table via Drizzle migration.
+
+```ts
+quantity: integer("quantity").notNull().default(1),
+```
+
+### Validation
+
+Add to `createItemSchema` in `src/shared/schemas.ts`:
+```ts
+quantity: z.number().int().positive().optional(),
+```
+
+Flows to `updateItemSchema` via `.partial()` automatically.
+
+### Service Layer
+
+No special business logic — quantity is a stored field.
+
+**Totals computation changes:**
+- `totals.service.ts`: `getCategoryTotals()` and `getGlobalTotals()` must multiply `weightGrams * quantity` and `priceCents * quantity` in their SQL SUM aggregations.
+- `setup.service.ts`: `getSetupWithItems()` and `getAllSetups()` — when computing setup totals, multiply item weight/price by the item's quantity.
+
+### UI
+
+- **ItemForm**: Number input for quantity (min=1), placed below price field. Defaults to 1.
+- **ItemCard**: Show "x2" badge next to item name when quantity > 1. No badge when quantity is 1.
+- **Totals**: Already computed server-side with the quantity multiplication. No client-side changes for totals.
+- **Setup weight/cost**: The item's quantity determines its weight/cost contribution when included in a setup (one `setup_items` row, but totals reflect quantity).
+
+### Thread Resolution
+
+When a thread is resolved and a candidate is copied to an item, the new item gets `quantity: 1` (default). No special handling needed.
+
+## Feature 3: CSV Import/Export
+
+### Export
+
+**Endpoint:** `GET /api/items/export`
+- Returns CSV with headers: `name,quantity,weightGrams,priceCents,category,notes,productUrl`
+- `Content-Type: text/csv`
+- `Content-Disposition: attachment; filename="gearbox-export.csv"`
+- Weight in grams, price in cents (raw values, no formatting)
+- Category column contains category name (not ID)
+
+**Service:** `exportItemsCsv(db)` returns a CSV string. Joins items with categories for name lookup.
+
+### Import
+
+**Endpoint:** `POST /api/items/import`
+- Accepts multipart form upload (CSV file)
+- Parses rows, validates required fields (name is required, others optional)
+- Category matching: looks up by name (case-insensitive). Creates new category if not found.
+- Quantity defaults to 1 if not present in CSV
+- Returns `{ imported: number, created_categories: string[], errors: string[] }`
+- Skips rows with errors, continues processing remaining rows
+
+**Service:** `importItemsCsv(db, csvContent: string)` parses and inserts items.
+
+### UI
+
+Settings page gets an "Import/Export" section:
+- "Export CSV" button — triggers download via `GET /api/items/export`
+- "Import CSV" file input — accepts .csv files, shows count of parsed rows, confirm button to upload
+- Success/error feedback after import completes
+
+## Feature 4: Item Duplication
+
+### API
+
+**Endpoint:** `POST /api/items/:id/duplicate`
+- Copies all fields from source item: name, weightGrams, priceCents, categoryId, notes, productUrl, imageFilename, imageSourceUrl, quantity
+- Appends " (copy)" to the name
+- New `createdAt`/`updatedAt` timestamps
+- Returns the new item
+
+**Service:** `duplicateItem(db, id)` — fetches source item, inserts copy, returns new item.
+
+### UI
+
+- Add "Duplicate" action to ItemCard (alongside existing edit/delete actions)
+- Duplicating opens the edit panel pre-filled with the new item so the user can rename or adjust
+
+## Phase Ordering
+
+1. **Item Quantity** — schema change first since CSV import/export and totals depend on it
+2. **Setup Impact Preview** — execute existing Phase 13 plans
+3. **Item Duplication** — small, self-contained
+4. **CSV Import/Export** — depends on quantity field existing in schema
+
+## Out of Scope
+
+- Quantity per setup (setup_items.quantity) — items table quantity is sufficient for v1.4
+- CSV export with formatted weights/prices — raw values are more portable
+- Image export/import via CSV — images are local files, not CSV-compatible
+- Bulk edit from CSV preview — import creates, doesn't update existing items

Jean-Luc Makiola	fb925a9dce	fix: include quantity in getAllItems select, createItem values, and updateItem type All checks were successful CI / ci (push) Successful in 24s Details CI / ci (pull_request) Successful in 25s Details CI / e2e (push) Successful in 1m3s Details CI / e2e (pull_request) Successful in 1m1s Details Quantity was missing from three places in item.service.ts: - getAllItems didn't select it (API returned undefined) - createItem didn't pass it to insert (always used DB default of 1) - updateItem type didn't include it (silently stripped from updates) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-03 19:57:25 +02:00

Jean-Luc Makiola	33f735af67	fix: remove scale/shadow whileDrag effect that stuck after release Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-03 18:50:49 +02:00
Jean-Luc Makiola	f8a1a00e0a	fix: prevent snap-back after drag and click-opens-edit during drag Two fixes: - Remove onSettled clearing tempItems before refetch completes, let useEffect clear it when fresh server data arrives - Track isDragging ref to suppress edit panel click after drag - Remove layout="position" which interfered with reorder detection Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-03 18:49:39 +02:00
Jean-Luc Makiola	27c36b6b9a	fix: make entire candidate row draggable instead of handle-only Remove dragControls/dragListener pattern which prevented onReorder from firing. The whole row is now the drag target with visual feedback (scale + shadow). Grip icon remains as a visual indicator. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-03 18:46:52 +02:00
Jean-Luc Makiola	684cfd3789	fix: stabilize drag-to-reorder with layout animation fixes - Remove transition-all from list items (fights framer-motion layout) - Add layout="position" to Reorder.Item for proper sibling tracking - Replace CSS gap with marginBottom (gap confuses layout engine) - Add explicit short transition duration for snappy reorder Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-03 18:44:39 +02:00
Jean-Luc Makiola	52751ae9d4	fix: use onDragEnd on Reorder.Item instead of onPointerUp on Group The previous approach used onPointerUp on the Reorder.Group which fired unreliably — triggering on non-drag clicks and sometimes not at all after a drag. Moving to onDragEnd on each Reorder.Item gives clean, predictable drag-to-reorder behavior. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-03 18:42:16 +02:00
