Quick notes and actionables

• Prefer explicit test setup when clarity matters, especially in larger suites.

• Use Time or Rails time helpers to avoid subtle timezone bugs.

• SolidQueue is a good fit when you want background jobs without extra infrastructure.

• create_with helps keep defaults consistent across find or create flows.

• Smart retry strategies reduce noise, protect external APIs, and improve reliability.

Just sharing a few reads I found useful. If one of these sparks something, I’d love to hear what you build or how you adapt the ideas.
