Code walkthrough

Follow a real flow through real source.

Steps

1. Choose the question and entry point: a request, command, event, or screen. Inspect repository structure and identify the actual files before explaining.

2. Follow that path in execution order: inputs, transformations, dependencies, outputs, and error handling. Link each step to a file and symbol or line reference.

3. Extract short snippets from the source rather than recreating code from memory. Distinguish observed implementation from inferred intent or uninspected dependencies.

4. Include one concrete example through the flow and identify tests that exercise it. Do not claim the code was run unless it was; keep static analysis separate from runtime evidence.

5. Finish with a small map, important invariants, and the next file to read. Match depth to the learner rather than narrating every file alphabetically.

Output

Flow map | source references/snippets | example trace | key invariants | unknowns.
