Walkthrough process (deep review)

Core intent

Use this skill to produce a high-context walkthrough for a reader who is new to the repo.

Default mode is process walkthrough:

• explain how a named function/module/flow works
• show where it sits in the larger system
• trace entrypoint -> internal steps -> successful outcome

Branch-change walkthroughs are supported, but all change-specific instructions are isolated in Branch change mode (only when requested) near the end of this file.
