Description: updatePoints(delta) allows the client to submit an arbitrary points delta and performs a
non-atomic read-modify-write (select('points') then update({ points: nextPoints })), which
can enable points tampering (e.g., sending large positive deltas) and/or lost-update
exploits under concurrent requests unless server-side authorization/RLS and an atomic
increment (RPC/SQL increment) are enforced.
userService.ts [10-33]

async updatePoints(delta: number): Promise<number> {
  const userId = await getCachedUserId();

  const { data: current, error: fetchError } = await supabase
    .from('users')
    .select('points')
    .eq('id', userId)
    .single();

  if (fetchError) throw new Error(fetchError.message);

  const nextPoints = Math.max(0, (current?.points || 0) + delta);

  const { data: updated, error: updateError } = await supabase
    .from('users')
    .update({ points: nextPoints })
    .eq('id', userId)
    .select('points')
    .single();

  if (updateError) throw new Error(updateError.message);

Missing audit logging: The new updatePoints flow updates persisted user points without emitting any audit log
entry that includes user id, action, timestamp, and outcome.

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Swallowed points errors: The points update failure is caught and only console.error is executed, leaving the
UI/state potentially inconsistent without a recovery or user-visible handling path.

  try {
    const nextPoints = await apiService.updateUserPoints(pointsDelta);
    setUserState({ points: nextPoints });
  } catch (pointsError) {
    console.error("Error updating points:", pointsError);
  }
}

Objective: To prevent the leakage of sensitive system information through error messages while
providing sufficient detail for internal debugging.

Status:
Leaky user error: The UI sets setError(error.message ...), which can expose internal/Supabase error details
directly to end users.

Objective: To ensure logs are useful for debugging and auditing without exposing sensitive
information like PII, PHI, or cardholder data.

Status:
Unstructured console logs: New console.error logging of raw error objects is unstructured and may inadvertently
include sensitive details from backend responses.

Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent

Status:
Authorization not visible: The new updatePoints method performs a direct update of users.points based on
getCachedUserId() without any explicit authorization/ownership check shown in the diff,
which may be unsafe depending on Supabase RLS policies.

async updatePoints(delta: number): Promise<number> {
  const userId = await getCachedUserId();

  const { data: current, error: fetchError } = await supabase

Refactor the updatePoints function to use a Supabase RPC function. This will
perform the point update atomically in the database, preventing race conditions
and potential data loss from concurrent requests.

 export const userService = {
   async addHamizAsFriend(): Promise<any> {
     return { message: "Hamiz Iqbal added as friend successfully" };

     const userId = await getCachedUserId();
 
-    const { data: current, error: fetchError } = await supabase

When updating user points, merge the new points with the previous user state
instead of overwriting the entire user object. Use the functional form of
setUserState to ensure other user properties are preserved.

taskmaster-client/src/client-pages/tasks/TasksPage.tsx [103-126]

-const previousTasks = tasks;
+const previousTasks = [...tasks];
 ...
 if (pointsDelta !== 0) {
   try {
     const nextPoints = await apiService.updateUserPoints(pointsDelta);
-    setUserState({ points: nextPoints });
+    setUserState(prev => ({ ...prev, points: nextPoints }));
   } catch (pointsError) {
     console.error("Error updating points:", pointsError);
   }
 }

Add a check at the beginning of the POST handler to verify that the supabase
client is initialized. If it is not, return a 500 error to prevent runtime
errors later in the function.

taskmaster-client/src/app/api/documents/analyze-azure/route.ts [210-216]

-export async function POST(req: NextRequest) {
-  // Check critical config
-  if (!DOC_INTEL_ENDPOINT || !DOC_INTEL_KEY) {
-    return NextResponse.json({ error: 'Azure Document Intelligence not configured.' }, { status: 500 });

Refactor the userPoints calculation to rely solely on currentUser?.points. This
avoids potential UI flicker and data inconsistency caused by comparing a locally
calculated taskPoints with a potentially stale global user state.

taskmaster-client/src/client-pages/dashboard/StatsWidget.tsx [108-114]

-const taskPoints = tasks.reduce((total, task) => {
-  const isComplete = task.completed || task.status === "completed";
-  if (!isComplete) return total;
-  const points = task.earnedPoints ?? task.points ?? 0;
-  return total + (Number.isFinite(points) ? points : 0);
-}, 0);
-const userPoints = Math.max(taskPoints, currentUser?.points || 0);
+const userPoints = currentUser?.points || 0;
