The C\nsource for git v2.47.0 is at `/home/workspace/git-src/` — read it, understand it, and\nrewrite it. Your binary must behave identically to the real `git` — same CLI\ninterface, same output formats, same exit codes.\n\nYour workspace is `/home/workspace/zig-port/` with a build scaffold that already compiles\nand links zlib. `zig build` produces `zig-out/bin/git`. The system `git` is\ninstalled — use it to test your implementation as you go.\n\nNo internet. Do not compile or link the C source or wrap around the existing git binary — write Zig.\nWork autonomously, do not ask user for input.\n"
