Test Slice Task

Problem

A Hanami team needs help with a task in this area:

Test a Hanami slice in isolation — write the test first to verify it fails for the right reason, load only the slice under test with :slice RSpec metadata tag, mock cross-slice dependencies, never reach into another slice's internals, a slice test must NOT depend on another slice booting, test the public interface through action specs with stubbed operations, operation specs with test doubles through constructor, repository specs against a test database, and integration specs across the full slice workflow, and when testing cross-slice interactions, stub the public interface or use shared test helpers rather than instantiating another slice's internals.

The team has asked for a concise implementation artifact that a reviewer can inspect without needing to observe the agent's process.

Output

Create answer.md with:

• a short plan for the work
• the concrete Hanami-oriented artifact or recommendation
• the verification steps or quality gates that should be run
• any assumptions that affect the result
