Overview

Executor encapsulates the full execution pipeline for an action. It owns all the wrapper logic that was previously spread across instance methods, reducing the number of methods injected into user classes.

The execution pipeline has two zones separated by the exception boundary:

**Outside zone** (result settled, must not raise):

  • nesting_tracking: manages the axn stack

  • tracing: reads result.outcome, result.elapsed_time, result.exception

  • logging: reads result.ok?, result.outcome, result.elapsed_time

Boundary:

  • exception_handling: catches exceptions, sets result state, dispatches callbacks

**Inside zone** (can raise fail!/done!):

  • timing: sets elapsed_time via ensure

  • contract: validates inputs/outputs, applies defaults/preprocessing

  • hooks: user before/after/around hooks
