The artifact names its Blueprint version, its generator and the agents behind it.

Recorded at the moment of build

Provenance is captured by the system doing the work, at the time it does it. Nobody fills in a form afterwards, and no side register drifts out of date. The record travels with the artifact instead of living in a wiki beside it.

Enough detail to rebuild

The record holds the Blueprint version, the generator and capability versions, the policy profile and the dependency versions pinned at build time. The Blueprint says what the software must mean; the generator and its target adapter decide what it is built with, and both are named here. Give the same inputs and the same artifact comes back — output does not drift from one run to the next.

Agent contributions are named

Where an agent contributed — architecture, implementation, review, QA — the record names which agent and for what. A reader can confirm that the agent which reviewed a change is not the agent that wrote it, without taking anyone's word for it. The model provider behind each agent is recorded too, so a routing change stays visible months later.
