Vue: Sessionize event activity for composable request activity stream

A high-traffic UI flow produces inconsistent ordering between initial load and refresh. The affected area is composable request.

Repair the composable request activity stream implementation so it splits activity after the configured inactivity gap and counts sessions per actor.

Evidence

Affected surface: Vue / composable request.
Observed failure family: sessionize event activity.
Scope policy: region must equal eu-west.

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 hard 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.
