commitid
commitid refers to the unique identifier assigned to a specific commit in a version‑control repository. In distributed systems such as Git it is a cryptographic hash generated from the commit’s contents, metadata, and its parent commit identifiers, ensuring that any change to the commit alters the value.

The commitid serves several practical purposes. It is the canonical reference used when pulling, cherry‑picking, or
Different version‑control systems represent commit identifiers in varying ways. Subversion uses sequential revision numbers that are
Best practices for working with commitids include using short, deterministic prefixes when referencing commits in conversation,
