llm-signature

Sign agent-assisted work with a machine-generated provenance signature: an Assisted-By git trailer naming the exact model that wrote and orchestrated the change, and an Agent-Stack trailer naming the harness and plugin versions it ran on. Use when committing or writing a PR body in a project that adopts the signature, when asked to sign a commit with the model / add model attribution or an LLM signature, when asked which model or tool stack produced a change, or when replacing Co-Authored-By AI boilerplate with provenance trailers. The signature is rendered by a script from live sources, never typed from memory, and the model is listed only in Assisted-By — never as a commit co-author. Not for human authorship credit (real co-authors keep their Co-Authored-By lines).
