Refactor: $ARGUMENTS

Follow Daniel Okoye's architecture standards:

1. Baseline: Run the test and type-check commands (see project config) BEFORE making any changes. If either fails, fix existing issues first — never refactor on a broken baseline.

2. Analyze: Read the code to be refactored and all its callers

   • Map the dependency graph: who imports/calls this code?
   • Identify the layer: Core → Service → API
   • Check for test coverage of current behavior

3. Refactor rules:

   • Preserve the public API — same function signatures, same return types
   • If renaming, update ALL callers and tests in the same commit
   • Maintain layer boundaries (see Layers in project config) — never reverse dependency flow
   • Keep route handlers thin — if moving logic, move it INTO service layer, not out
   • All service access still via DI injection (see stack concepts) — no direct imports in API layer
   • Keep future annotations pattern in every file (see stack concepts)
   • No new untyped/any types — use explicit types

4. If splitting files:

   • Update __init__.py exports if needed
   • Ensure no circular imports between layers
   • Each new file follows the future annotations pattern (see stack concepts)
