Git Branch
A Git branch is a named pointer that can move from one commit to the next. When new commits are made on that checked-out branch, the pointer moves forward.
Another example
main points to commit A when a developer creates invoice-export. Two new commits move invoice-export forward while main stays at A until the work is combined. A branch is a pointer, not a full copy of all files or a separate deployment environment.
Main parts
- 01branch ref
- 02target commit
- 03commit graph
Use it when
Use this term for a named, movable line of work in the Git commit graph.
Do not use it when
Do not assume a branch gives runtime isolation, access control, backup, or history apart from commits and references.

Before publishing, check the exact repository, branch, target, and diff. Keep unpublished work. Pass review and CI checks. Record conflict and data-loss risks, release order, traceability, recovery, and rollback.
Outcome: Use Git Branch to release or recover the change safely, with a clear record. User context: main points to commit A when a developer creates invoice-export. Two new commits move invoice-export forward while main stays at A until the work is combined. A branch is a pointer, not a full copy of all files or a separate deployment environment. Delivery concept or operation: Git Branch. Why it fits: Use this term for a named, movable line of work in the Git commit graph. Do not use it when: Do not assume a branch gives runtime isolation, access control, backup, or history apart from commits and references. Delivery requirements: Name the code repository and target. List preconditions, changes, review and CI checks, conflict and data-loss risks, release order, and the rollback or recovery command. Repository safeguards: Keep unpublished work and a clear history. Do not run destructive steps without an explicit backup. Check the exact code diff and remote target before publishing. Acceptance criteria: Review the intended diff and pass all required checks. Keep the target version traceable. Practice failure recovery and keep published history clear. Evidence and limits (evidence boundary): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Repository, branch, team activity, release environment, approval owner, protected checks, and rollback target.
