NestJS: Redact sensitive fields for queue processor sensitive records

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

Repair the queue processor sensitive records implementation so it redacts configured sensitive fields without mutating unrelated values.

Evidence

Affected surface: NestJS / queue processor.
Observed failure family: redact sensitive fields.
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 easy 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.
