Android / Kotlin: Merge layered configuration for ViewModel state runtime configuration

A device lifecycle boundary exposes stale data when network and local state disagree. The affected area is ViewModel state.

Repair the ViewModel state runtime configuration implementation so it applies documented precedence and reports unsupported keys.

Evidence

Affected surface: Android / Kotlin / ViewModel state.
Observed failure family: merge layered configuration.
Scope policy: tenantId must equal tenant-primary.

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.
