Crime Scene Investigitor
summary
Explains Git internals (commits, trees, blobs, objects in .git/objects) and shows concrete CLI tools to investigate and fix repo crime: using git cat-file and git reflog to recover unreachable commits, binary-searching a regression with git bisect that isolates a single bad commit (B99), and permanently removing secret blobs by rewriting history with git filter-branch (notes git filter-repo as safer) plus the unavoidable step of force pushing all branches and tags.
