A git commit is a snapshot of the repository state at a point in time. Commits form a directed acyclic graph (DAG) where each commit references its parent(s). Each commit records the author, timestamp, a message describing the change, and a tree object representing the file system state at that moment. Commits are identified by SHA-1 hashes computed from their contents, making them content-addressed and tamper-evident: altering any part of a commit changes its hash, which in turn invalidates all descendant commits. In an Agential Semioverse Repository, commits serve as the provenance mechanism. Each change to the vault state is recorded as a commit with an author and a description, creating an audit trail of how the repository evolved over time.
