+# todo-api
+
+A minimal zero-dependency in-memory todo list library for Node.js.
+
+## API
+
+```js
+import { TodoStore } from './src/todo.js';
+
+const store = new TodoStore();
+
+const id = store.add('buy milk');   // returns numeric id
+store.list();                        // returns [{ id, text, done }]
+store.remove(id);                    // deletes item
+store.complete(id);                  // NOT IMPLEMENTED — marks item done
+```
+
+## Status
+
+The `complete(id)` method is **missing**. The test suite in `src/todo.test.js` covers it and currently fails:
+
+```
+node --test src/todo.test.js
+# → TypeError: store.complete is not a function
+```
+
+## Task
+
+Implement `complete(id)` on `TodoStore` in `src/todo.js` so that it:
+
+1. Finds the item with the given `id`.
+2. Sets `item.done = true`.
+3. Does not throw if `id` is not found (silent no-op).
+
+All five tests in `src/todo.test.js` should pass after the fix.
