## TL;DR

Git is the change-control substrate for AI coding agents. It records the object graph, branch pointers, commits, and merges that make automated code changes reviewable and reversible.

## Core Explanation

Git stores repository content as objects. Branches point to commits, commits are created from staged content and metadata, and merges combine development histories. These mechanics matter because an agent should work in small patches, preserve user changes, and leave a clear recovery path.

## Detailed Analysis

For AI-assisted development, Git is not just a deployment tool. It is evidence: what changed, when it changed, which tests were run before commit, and whether generated files or secrets were excluded. Agents should inspect status before editing, stage only intended files, commit after successful gates, and avoid destructive history operations unless explicitly requested.
