Rails Service Object Patterns

Analyze and recommend patterns for extracting and organizing business logic in Rails applications.

Resolve the axis first

This skill forks on Axis A — logic placement. Before recommending where logic goes:

1. If the axes are already resolved this session, use them.
2. Otherwise resolve via rails-stack-profiles (Axis A only — native or extracted).
3. Then read the matching extraction guide:
   • native → extraction.native.md
   • extracted → extraction.extracted.md

If the axis cannot be resolved, default to native and state the assumption.

Everything else in this file is invariant — it holds regardless of axis.
