Spring: Evaluate feature flags for repository query feature rollout

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

Repair the repository query feature rollout implementation so it evaluates segment constraints and stable rollout buckets.

Evidence

Affected surface: Spring / repository query.
Observed failure family: evaluate feature flags.
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 medium 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.
