Cloud-native full-stack: Choose a safe refactoring boundary for deployment control module boundary

A distributed workflow needs a localized repair without weakening observability or rollback safety. The affected area is deployment control.

Repair the deployment control module boundary implementation so it ranks change-prone modules, preserves ownership boundaries, and identifies where characterization tests are required before extraction.

Evidence

Affected surface: Cloud-native full-stack / deployment control.
Observed failure family: choose a safe refactoring boundary.
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.
