The idea in one minute

Start with meaning, then move to detail.

This lesson explains Codebase Ownership Map as part of Hermes internals and extension points. You will learn what it does, when it matters, and the smallest safe test that proves it works.

If you are new

If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?

For hands-on use

For practice, open the source, choose one section, and write an expected result before changing configuration.

For specialists

For advanced readers, inspect the page structure and linked references, then verify failure modes and version compatibility.

What do you need first?

Know Python, Git, and basic project structure before changing code.

What will you know?

A clear outcome before you read.

  • Understand Codebase Ownership Map without assumed prior knowledge.
  • Separate the source description from what still needs testing in your environment.
  • Write one sentence describing what should change after applying this topic.
Official page description

Which directories belong to which subsystem, and where the right docs entry point lives for each

Topic map

What does the source say, and in what order?

This is a short reference page. Open the source for the final detail and update date.

Try it now

Write one sentence describing what should change after applying this topic.

Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.

Knowledge check

Three decisions before completion.

1. What is the source of truth when “Codebase Ownership Map” changes?
2. What is the best way to apply this lesson?
3. What should happen before a step can modify files or an external account?
