Build a mental model of unfamiliar code: what it does, how it's structured, and why.
Why it works: Telling the model your background calibrates the altitude of the explanation; asking what to read next turns one answer into a map.

I’m trying to understand the following code. Help me build a mental model of it.
Code:
My background with this codebase: [e.g. “brand new to it”, “familiar with the domain but not this service”, etc.]
What I’m trying to understand: [e.g. “the overall flow”, “why this data structure was chosen”, “what happens when X”]
Please explain:
- What it does: the purpose and high-level behavior
- How it’s structured: key components and how they relate
- Why it works the way it does: any non-obvious design decisions or constraints
- What to read next: if there are likely entry points or related areas worth looking at, point them out
