Advanced Git: Rebase, Recovery & Branching Strategies

Go beyond the basics: interactive rebase for history sculpting, cherry-pick extraction, deep 3-way merge conflict resolution, reflog disaster recovery, annotated tags for releases, git bisect for regression hunting, worktrees for parallel development, and GitFlow vs trunk-based branching strategies.

The AI Era Demands More

Become the Engineer Who Supervises AI

As AI generates more code, understanding what that code does becomes more valuable, not less. Someone must verify AI output, debug failures, and make architectural decisions.

Build Your Architectural Edge

You run Git commands every day without seeing what they do to your commit graph.

The gap between knowing commands and understanding Git

You've run git rebase -i and hoped nothing broke. You've lost commits to a git reset --hard with no idea how to get them back. You've stared at merge conflicts, guessing which side to keep because you couldn't identify the merge base. AI suggests Git commands too, and you accept them because the alternative is decoding man pages for half an hour. Every one of these moments comes down to the same root cause: you can't see what Git does to parent pointers, hashes, and branch references when a command runs. Without that visibility, you can't predict outcomes or recover when things break.

See Git's invisible mechanics in real-time

Interactive simulations that make commit graph operations visible and predictable.

Watch rebases rewrite history

Step through an interactive rebase and see parent pointers change, new cryptographic hashes generate, and old commits become unreachable on a visual commit graph.

Trace recovery paths through the reflog

Follow chronological HEAD movements, see how orphaned commits remain accessible through reflog entries, and practice restoring lost work after hard resets and deleted branches.

Step through binary search debugging

Watch git bisect narrow a regression to one commit, seeing each midpoint checkout and how the algorithm eliminates half the remaining history at every step.

What's Covered

Eight lessons covering history rewriting, conflict resolution, disaster recovery, debugging, and team branching architecture.

History Sculpting

Rewrite, reorder, squash, and cherry-pick commits to shape a clean, intentional timeline before sharing your work with the team.

Merge Mechanics & Conflict Resolution

Understand 3-way merge algorithms, identify the merge base in criss-cross topologies, and resolve multi-file architectural conflicts using diff3 format.

Disaster Recovery & Debugging

Recover orphaned commits through the reflog after hard resets, deleted branches, and botched rebases. Isolate regression bugs to a single commit with git bisect.

Team Workflows & Release Management

Choose between GitFlow and Trunk-Based Development for your team, manage releases with annotated tags and SemVer, and run parallel workstreams using git worktree.

The Curriculum

Comprehensive Lessons! Each with theory, interactive simulation, and quiz.

Interactive Rebase: Sculpting Local History

The git rebase -i interface and its interactive todo list. Squash minor fixes, reword commit messages, and reorder history before sharing. See how rewriting commits generates new cryptographic hashes and rewrites parent pointers across the modified chain.

Surgical Extraction: Git Cherry-Pick

Isolate and extract specific commits from divergent branches using git cherry-pick. Target commits by hash, understand how diff patches are duplicated and applied onto your current HEAD, and resolve conflicts when the target branch lacks the necessary foundational context.

Deep Dive: 3-Way Merges and Complex Conflicts

The mechanics of 3-way merge resolution. Identify the closest common ancestor (merge base), navigate criss-cross topological histories, interpret diff3 format output, and safely integrate divergent multi-file architectural changes.

Disaster Recovery and the Git Reflog

The reflog as Git's local, time-stamped journal of every HEAD movement. Track chronological pointer changes, recover unreachable commits lost to accidental hard resets, deleted branches, or botched rebases, and decode reflog syntax to restore orphaned data.

Release Management with Annotated Tags

Lightweight tags (simple pointers) versus annotated tags (full Git objects with author metadata, dates, and cryptographic signatures). Attach tags, push them to remotes, trigger CI/CD pipelines from tag events, and integrate Semantic Versioning (SemVer) into your project graph.

Archaeological Debugging: Git Bisect

Automate regression bug hunting with git bisect. Define good and bad endpoints, let binary search check out midpoint commits automatically, and isolate the exact cryptographic snapshot that introduced a bug with mathematical efficiency.

Parallel Architecture: Git Worktrees

Check out multiple branches simultaneously into separate physical directories using git worktree. Understand how a shared .git folder powers isolated working trees, and manage the full lifecycle of linked worktrees from creation to cleanup.

Branching Strategies: Trunk-Based vs. GitFlow

Compare GitFlow's long-lived branches (feature, develop, release, main) with Trunk-Based Development's short-lived feature branches and feature flags. Understand the mechanics, tradeoffs, and team dynamics behind each workflow architecture.

Git confidence built on seeing what actually happens

After this Deep Dive, you'll rebase local history, recover orphaned commits, resolve complex merge conflicts, and architect team branching strategies with full visibility into what Git does to your commit graph at every step. You become the engineer your team calls when the history breaks.
