Crime Scene InvestiGITor
summary
Covers Git internals (commits, trees, blobs under .git/objects) and concrete CLI workflows: git cat-file and git rev-list to inspect objects, using reflog to recover unreachable commits, checkout/reset/revert modes to time‑travel safely, and a binary search with git bisect that finds the first bad commit in a few test runs. Explains secret removal with a copy‑paste git filter-branch pipeline, warns about garbage collection, and notes the need to force‑push rewritten history.
