Android / Kotlin: Aggregate grouped totals for permission request reporting metrics

A device lifecycle boundary exposes stale data when network and local state disagree. The affected area is permission request.

Repair the permission request reporting metrics implementation so it groups records once and returns accurate counts and totals.

Evidence

Affected surface: Android / Kotlin / permission request.
Observed failure family: aggregate grouped totals.
Scope policy: retained must equal true.

What this task practices

This coding (platform) exercise trains the same sequence expected in an interview: understand the prompt, make assumptions explicit, produce a concrete answer, and explain the decisions behind it. The task is marked easy difficulty. The private workspace adds the tools required by this round, such as recording, code execution, diagrams, evidence panels, or structured notes. It also preserves the attempt so later feedback can be compared with previous work. Evaluation is based on task-specific criteria and the candidate seniority selected in the preparation path. Public pages never expose the reference solution, hidden tests, evaluator instructions, or another candidate’s work.
