Why it exists

Agent-assisted commits lose context fast.

Traditional audit trails can show that a workstation pushed a commit, but not whether an agent, model, CI task, or vendor tool produced the change. Matrix Scroll turns that gap into a signed commit envelope anyone can verify offline.

The protocol stays intentionally small: canonicalize the manifest, exclude the signature block, sign the bytes, publish the public key, and let anyone verify the result.
