Inside the .git folder - Explore the mysterious depths...
summary
Maps every file inside a .git directory to actual commands and bytes: shows commits/trees/blobs as objects with 40‑char hashes (first seven usually enough), explains that blobs are zlib‑compressed and stored under folders named by the first two hex chars (max 256), demonstrates git cat-file (-t/-p), inspects the index file with git ls-files and status, shows git gc creating pack files that store deltas (example: two loose blobs ~70 bytes → pack ~40 bytes) and uses git verify-pack/reflog to prove it.
