> Standardizing User ID Access & Fixing Task Fetching

# February 6th, 2026

**Critical Fixes: Identity Standardization & Data Fetching**

Today involved a major refactor to align our API endpoints with the updated authentication middleware and fix a critical data fetching bug that was hiding commitments in the native app.

***

## 🛠️ Major Backend Refactor

We standardized how User IDs are accessed across the backend to ensure consistency and security.

### Backend Changes (`convex/tasks.ts`)

* **Standardized ID Access**: Updated `delete` and `update` commitment mutations to correctly access `user._id` from the authenticated context.
* **Strict Typing**: Replaced legacy usage of `user.id` and `user.subject` to match the strict `Doc<"users">` type definition injected by the auth middleware.
* **Consistency**: Ensured consistent property access across the entire commitments API module.

## 📱 Frontend Fixes

### Task List Regression (`commits.tsx`)

A regression was identified where the task list query was passing a hardcoded `"user_id"` string, causing the list to appear empty.

* **Fixed Regression**: Updated the query to use the actual authenticated user's ID.
* **Conditional Querying**: Implemented proper session-based conditional querying. The `list.byAssignee` query now waits for a valid `session.user.id` before firing (using the "skip" pattern).

```typescript theme={null}
// Old (Bugged)
const tasks = useQuery(api.tasks.list, { userId: "user_id" });

// New (Fixed)
const userId = session?.user?.id;
const tasks = useQuery(
  api.tasks.list, 
  userId ? { userId } : "skip"
);
```

## ✅ Result

This resolves the critical issue where created commitments were not appearing in the main list view. The app now correctly fetches and displays tasks for the logged-in user immediately after creation.
