Express: Allocate limited capacity for search endpoint capacity pool

A production request path returns inconsistent decisions during retries and concurrent updates. The affected area is search endpoint.

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

Evidence

Affected surface: Express / search endpoint.
Observed failure family: allocate limited capacity.
Scope policy: cohort must equal stable.

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.
