15-15: Import of new interface looks good.
The addition of the IUser interface is consistent with the need to pass the optional user parameter for filtered tasks.

20-20: Ensure the optional user prop behaves as intended.
Declaring the user parameter as optional with user?: IUser is appropriate. Be mindful that subsequent code correctly handles the case when user is undefined or null.

13-13: Good introduction of the IUser import.

This import properly sets up type definitions for the new user-based filtering logic.

18-26: New user prop in component signature is clear.

Allowing an optional user prop is a clean solution for user-based filtering. However, ensure that any consumer of <PastTasks> properly handles the case when user is undefined.

30-30: State initialization looks good.

Using _pastPlans from the hook to set the initial component state is consistent with existing patterns. No issues here.

51-51: Check for potential infinite re-render in useEffect.

The effect depends on pastPlans and calls setPastPlans, which might produce a new array reference each time. Confirm that the filtering step is idempotent or that the equality check prevents unnecessary renders.

55-55: Conditional rendering for empty pastPlans looks good.

The fallback to <EmptyPlans> clarifies the UI experience when there are no tasks.

56-56: Drag-and-drop context is well-integrated.

Passing setPastPlans to the handleDragAndDrop callback is consistent with the rest of the daily plan flows.

62-62: Mapping through pastPlans is straightforward.

Generating an <AccordionItem> for each plan and rendering tasks is an idiomatic approach that maintains readability.

2-2: Adding IUser import looks correct.
No issues noticed with importing IUser alongside IDailyPlan.

50-63: Validate task filtering logic & consider potential performance improvements.
The logic correctly filters tasks by user membership. However, if any step in the pipeline (e.g., plan.tasks, plan.tasks?.filter(...)) is large, this could become costly. If applicable, consider optimizing by short-circuiting or partial loading of tasks.

11-11: IUser import is consistent with the new user-based filtering.
No issues with the new import.

16-16: Optional user prop enhances flexibility.
Including user?: IUser is a good approach for optional filtering.

18-18: Prop destructuring is straightforward.
Well done on passing user as a prop.

23-28: Implement fallback or defensive checks on user tasks.
The filtering is correct, but you might consider an additional null check to handle unexpected data or missing members gracefully.

12-13: useEffect and IUser import introduced.
Looks good. The useEffect is presumably used for re-filtering tasks when user changes.

17-17: Optional user prop addition.
Using the same pattern as in the other files for user-based filtering.

19-23: Initialize local plans state from outstandingPlans.
No immediate concerns; just ensure plans is always in sync with outstandingPlans if future logic calls for updates.

42-49: Rendering logic with plans?.length > 0
No issues found. Logic for handling empty vs. filtered state is good.

129-129: Passing user to UserProfileTask
Good approach to ensure user-specific tasks are displayed. Verify that member?.employee?.user is not undefined.

29-29: Import usage approved.

Bringing in the IUser interface here is consistent with the new feature requiring user-based filtering.

58-60: New interface definition looks good.

Defining IUserProfilePlansProps with an optional user?: IUser; is a clean approach to handling user-based filtering.

62-62: Function signature updated properly.

Explicitly accepting props implementing IUserProfilePlansProps ensures type safety and clarity in usage.

65-65: Destructuring the user object.

Assigning user from props is straightforward. Ensure any function calls within this component take into account when user may be undefined.

85-86: Unified approach to outstanding tasks.

Passing the user prop to <OutstandingAll> and <OutstandingFilterDate> ensures consistent user filtering in outstanding tasks.

89-92: Ensuring user-based filtering across tabs.

All daily plan tab components now accept user for filtering tasks. This aligns with the objective to show only tasks belonging to the correct user.

303-311: AllPlans function signature updated.

Including an optional user prop aligns this function with the rest of the user-specific filtering architecture. Great job maintaining consistent types.

11-11: Import referencing also looks good.

Importing IUser allows passing the user object for more granular task filtering.

17-17: Optional user prop.

Declaring user?: IUser; in Props ensures backward compatibility for components that do not require user-based filtering.

25-25: Enhanced function signature.

Adding user to UserProfileTask parameters aligns with the new feature, enabling user-bound task filtering logic.

98-98: Passing user object to the daily plan.

Connecting user ensures the daily plan displays the correct tasks, addressing the PR’s main objective of removing cross-user task duplication.
