NestJS: Allocate limited capacity for queue processor capacity pool

An operational alert points to a contract bug that appears only under mixed production data. The affected area is queue processor.

Repair the queue processor capacity pool implementation so it allocates limited capacity by priority without exceeding demand or the global limit.

Evidence

Affected surface: NestJS / queue processor.
Observed failure family: allocate limited capacity.
Scope policy: authorized 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 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.
