Once the system is framed as states, transitions, and tool boundaries, it becomes easier to reason about:

  1. which stage the request is in,
  2. what context must be preserved,
  3. and what should retry versus hard-stop.

For a personal technical site, the point is not to claim a final answer. The point is to make the reasoning path legible and reusable.
