iOS / Swift: Allocate limited capacity for deep link router capacity pool

A state restoration path produces a user-visible duplicate after an interrupted session. The affected area is deep link router.

Repair the deep link router capacity pool implementation so it allocates limited capacity by priority without exceeding demand or the global limit.

Evidence

Affected surface: iOS / Swift / deep link router.
Observed failure family: allocate limited capacity.
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 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.
